News about my SVX.
 

Ok, I recently went down to fernly, finally, and found out just how slow my car really is up in this elevation. I almost ran an even 16 on my best run but I was as high as 16.2.

The supercharger setup is still not here yet which has me beyond frustration since I probably wont get it until its in winter and it will be un-usable. But since I have been waiting I have been giving some serious thought to what else needs to be done to the car. I have been looking into my options wheel wise, with brake upgrades in mind, and I have settled on one fo two wheels. Most likely I am going to end up going with superleggaras unless by some act of God I find watanabe cyclones in the US for a half decent price. I am also going to be taking out more of the interior for the meantime before I completly redo the inside. I have decided I am going to go with a sparco pro 2000 seat which I will have to have custom brackets and mounting for it made. Do you guys know of anywhere special I should go for that? I need to also see about having a piece of lexan put in for my back window, for several reasons, do we know anywhere for that in or around town?

Pretty soon I would like to switch over to a new lightweight battery, and in the process move it to the trunk. Is there anyway any of you could help a brother out with that? I am also looking to have a custom box made to keep it encloused in the trunk since I will probably be using a battery that doesnt produce gas.

And finally, I am still unsure of what route to go with my transmission. Ideally I would like an automatic tranny that can hold gobs of horsepower, be streetable, and have somewhere around a 50/50 split. I don't know if such a thing even exists, or if such a thing could be custom made. But getting an sti 6 speed and then having to build it to withstand the horsepower I will be running just doesnt sound too good. After all, I have a budget.

Fern-tucky isn't the best place to get your car timed. Take it to fallon - a real track.

I didn't want to go that far. My time truly doesn't matter to me much I just needed something to base a before and after on.

Friend at IVM helped a customer swap an automatic 6 speed into his SVX last year. Not sure who the customer was, or if the same swap would suit your needs. Maybe someone with more experience knows...

An STi 6 speed can easily hold double what the stock STi puts down. I think it will be perfect for you. With a controller like Sperry uses, you can adjust the torque split too. Here's what Andrewtech charges to rebuild gears 1-4 of a WRX 5 speed:
If you drag, the stock 6 speed ratios aren't the best. so you may want to consider the 5 speed. You can choose what ratios you want.

I know you said you want an automatic, but I can't help you there.

I use an Odyssey battery. You can mount it upside down in a sealed container if you want, it works in Reno winters, and it's about $100 shipped with posts. Lots of Suby owners are using them and no failures have been seen yet.

Well before I do my engine rebuild I will be putting out 415 or more at the crank. After the engine rebuild I will be putting out well over 600. I need something that will be able to hold the power without a question of if it will actually hold. Although I am more than a year away from rebuilding the engine...I don't want to ever have to touch the tranny again (hopefully).

Thanks for the help so far, if you have anymore ideas shoot them my way.

P.S. I work on the nights meets are held >_>. New jobs for the lose.

A bone stock 6 speed will hold your 600 hp, but you'd want an Exedy twin plate or equivalent clutch. They hyper single will hold the power, but it not especially street friendly. I would not recommend relocating the battery; the cables you have to run cancel out the weight savings of the smaler battery, it's more of a handling mod which, frankly, isn't going to be noticeable in such a heavy car, stripped interior or no.

Im mainly relocating the battery to creat space under the hood for a few things I would like to do, not for weight savings.

Doesn't this thread already exist somewhere?

The 6MT will hold over 500 ftlbs of torque, assuming an adequate clutch. I know you think w/ your 600 hp build you might be maxing that out, but I can pretty much guarentee you'll never be making enough torque to break the 6MT unless you abuse the tranny. I'm pretty sure we went over all this, but if you really think your going to eventually make 600 hp, well you need to order a new block, new EM, new *everything*, have it all custom build by a professional drag or sand-rail place, and then you'll have a motor that can run maybe 1000 hours before needing to be scrapped and rebuilt... The motor you've got, the supercharger you've ordered, neither will ever get you into the 600 hp range. We've been over this before... you have totally unrealistic numbers in your head. For christ's sake, a Formula 1 motor only makes about 700 to 800 hp. You really think you can get 600 from an SVX block that was designed almost 20 years ago?

Anyway, if you build the motor you've got, you might make that 415 hp at the crank... which an STI 6MT will easily handle. Unless you're looking for something specific w/ the gearing, going w/ the STI tranny is all you need to do. But don't forget the custom axles, driveshaft, hubs, brakes, suspension and wheels you'll need to make it work.

You may think they are unrealistic expectatins but 415 is on the stock block, if you think I need a rebuild you are sadly mistaken because I don't. Not only will the power be reliable and streetable...but it is a very conservative tune. I am sorry you have no faith in my car whatsoever. But mark my words, I WILL make you eat your words when it comes to this. Just because you think I can't make the power doesn't mean its not possible. People used to think making the kind of power you guys make from a 4 banger was impossible. So I say the hell with your idea of impossible because I already know what kind of power I will be making as of the moment the supercharger is in. I have some amazing people lined up to do some work on the car, including dynamic in town. If you have any doubts as to what I am capable of or what my car is capable keep them to yourself until I fail. Once I fail you have evewry right to tell me how stupid, unrealistic, and foolish I was but until I do fail, please kindly STFU.

I have nothing but respect for you and all other members on this board. But please, step down from your high horse and treat me like a human being and not a piece of dirt. I treat you with respect, please try and return it. As far as the motor being 20 years old...go down to dynamic and test drive one of their cobras. My personal friend owns the one with the largest engine in it. An engine that was designed for longer than 20 years ago, that happens to be putting out 654 HP and 623 torque NA. You are a great driver but you act as if you are the absolute authority on every aspect of motorsports when you speak to me. You are just plain ignorant in bashing me in MY thread when frankly you don't know dick about what is and is not possible with the car. You have vast amounts of knowledge about cars and far more than I, but you don't and never will have the authority to say my project won't work, until the day it doesn't. I don't know if you have a problem with me personally, but whatever it may be...the way you treat me here is sub-human. I like you and understand that you don't think this is possible. Then grant me a hypothetical situation view on the situation. I currently have no one who I trust when it comes to the tranny aspect of my project and that is why I come here for help. I have nothing against you Scott, hope its the same towards me.

To those of you who are willing to help, thank you. I have contacted Andrew and I am currently waiting for a response. Sorry if I sound angry, but it is because I am personally offended despite the fact that I don't take posts on the internet all that serious.

To those of you helping me, I VERY much appreciate it

I'm sorry if I've offended you. I've got no problem with you personally. In fact, I enjoy your posts for the most part. I'm by no means attempting to demean you, or treat you "sub-humanly".

But, the fact remains, you have unrealistic expectations. You will not make 600 hp on that motor. It's not possible, not without a fresh block and tens of thousands of dollars in work. This has nothing to do w/ what I think about you personally. It has everything to do with the laws of physics. I've got an SVX, I've done research about what's possible with them. The sand rail guys are getting 600hp out of the EZ33, but to get there involves tons of work, most of which can't easily be packaged under the SVX's hood or used on the street (like massive turbos, alcohol fuels, etc). As the owner of a 400hp WRX that cost about $20,000, I can attest, getting to 600 hp w/ the EG33 in the SVX is going to be a $100,000 project. When you start talking about stuff like that, I can only believe it when I see it.

Again, don't take this personally, I respect you, and I admire your gumption when it comes to this project. But frankly, your expectations are unrealistic. How long's it been since you ordered that supercharger? I know that delay isn't your fault, but it speaks volumes to the difficulties in building reliable power adders for the SVX. If those fellas out in Florida that have been working on these things for over a decade can't get it working in 2 years +, how are you and the people you've got lined up here in Reno going to go so much further than them w/ no specific SVX experience?

I'm not saying give up, I'm not saying you're crazy, I'm not trying to insult you, I'm just saying get yourself some realistic goals and some attainable milestones. If you think you're going to build a 600 hp, 11 second SVX on your first (or even second, third or fourth) go at it, you're going to be disapointed, especially if you get your ego so wrapped up in the project.

Back on the topic, as I said earlier, an STI 6MT will easily hold the power that car will make on the supercharger kit you've got coming. But don't forget how much more work and fabrication is involved w/ the 6MT in the SVX.

Perrin "only" got 430whp from the Tribeca H6 and that was with GT35R Turbo, water injection, forged pistons and all the fixins. They've got a couple WRX's that will be even crazier though. I don't really have a point, but damn that's cool.

The bigger the engine you add a given turbo or supercharger to, the *less* horsepower it will make, although peak torque should be similar. This is because a bigger motor spools a turbo faster, and then the turbo runs out of efficiency sooner, and of course, RPM is part of the horsepower equation. In otherwords, a 550 whp turbo on a 2.5 liter motor is a 430 whp turbo on a 3.3 liter motor. Same for duckie's supercharger- it won't make 600 hp because it will make peak torque at lower engine speeds. 600 horsepower out of a 3.3 liter engine means a compressor that peaks its airflow at 5500-6000 rpm on that motor, or higher. Using an online turbo calculator, you'll see how nailing a horsepower goal is tougher with larger engines, because turbos get bigger very rapidly as you go past the GT30/32 range. It's probably exactly as easy and almost exactly as espensive to build a 1000 hp SVX as it is 600... except for the part where you have to make said engine actualy fit under the hood, as Scott mentioned. Moving the battery to make more room under there does make sense now. And seriously, nobody here has anything against you at all, but you do have pretty unrealistic expectations for this project, at least the way you have explained that you will go about it. Remind me again, what blower is used for the kit you are getting?

Sorry, I blew up on ya =/. Really you hit the nail on the head without trying to. My source of the frustration is the guy in Florida, this setup should have been done a long time ago and several members including myself (from the SVX network) have been working privately with him to try and change a few flaws we saw with the system and although he has fixed them...it has taken ages to do so. I unjustly took my fustration out on you and as you can tell I am super super defensive about this project, mainly because of the personal time and money I have invested in it.

The reason I have faith in the guys I am working with in Reno is pretty simple actually. Over the years I have known them they have repeatedly done the "impossible". They took all motor hondas too unthought of levels in the 80's, they were one of the first to drop a small block into a 944 porsche with amazing results, and at the moment they are most well known for building the most amazing cobras and GT40's in the nation. They also are the only north American dealers of Noble Kit cars along with the real deal(Some guy sells Nobles on the east coast now but his liscenc3e is up next year). One man in particular there, steven, consistantly blows my mind on every project I see him work on. I consider him a genious on getting things to work that by the laws of logic defy.

In no way do I want to come off as saying my car is going to be running 600 crank by next year. I will probably be well on my way to 30 before this project is done. What I am trying to find out now, is if I can afford to do the tranny only once, and not have to touch it for 5 years then it would be ideal. But if I end up only to have enough money to take it to a lvl where it can handle my current build then so be it. Scott, you may be interested to know that an incredibly affordable big brake kit is now available for the svx, its under 700 bucks and has amazing stopping power. It can be used with any wheel 17 and above, to my knowledge width is not a factor nor is the offset (any wheel that fits normally would fit the kit under it). It is going to be my temporary solution until I get to big power, but for a stock or nearly stock SVX the kit is more than overkill and should be PERFECT for you.

I am still trying to track down 18 inch Watanabe cyclone wheels. If ANY of you have some crazy ass JDM hook up guy, now is the time to tell me. If the wheels can be had for udner 3k, it will be where I go with wheels, otherwise its going to be some tired out played out wheel that everyone has which I will use ;).

Cody, the h6 in the tribeca IMO is a junk motor. By junk I mean average. I have followed every H6 project whether it be tribecas block or the EG33 and I can tell you that the EG33 is capabble of making more power, all be it a costly route. There are now several confirmed EG33 blocks making, sometimes, even more power than I am aiming to make on fairly reasonable budgets (read 50 grand). To my knowledge the EG33 is the ONLY approved engine for kit planes and it is amazingly bullet proof. When we started this project we thought 7 pounds of boost was all that was going to be possible on stock internals, low and behold it could take about 15 but the tranny could only tolerate 12 =). The problem with the tribeca engine is that it is a high interference engine and was a HUGE roadblock for perrin, and the few others who have taken it upon themselves to mess with it. Although the EG33 is not closed decked just like the Tribeca...it can, so far, withstand some pretty amazing shit that we have put it through.

Things for the SVX have never looked better, we finally have figured out ideal cams to be made for teh car which is a start and we obviously have much more to go if we want my dream to happen. Luckily, I have a large group of incredibly passionate people behind me when it comes to the project and thank God I am not working alone.

Major re aranging underneath my hood needs to occur before my next build. I am trying to source out a set of ragular, non ABS brakes to replace my curent ones to open up an important part underneath my hood. Battery is also at another crucial spot, out my washer tank will also go. Steven is really going to be a crucial part in getting everything to fit in the car but I have faith in him.

I am going to be using a 1600ax twin screw for some very specific reasons. Actually you hit the nose on the head when it comes to making power on a large engine by using turbos...there is a reason I did not go the turbo route and the reason why I went with a positive displacement supercharger as uposed to its brother. I may have to change to a larger model depending on how the next few years goes, but I may NOT have to. I have been talking with lysholm over in Sweden as far as how exactly this model works, what it is capable of and if there would ever be a need to use a larger model. They told me they garuantee I could make 500 easily without switching models...however they don't know past that although I won't bore you guys with specifics about the model...if you want to go look it up just google 1600ax whipple.

Oh, one more thing I totally forgot to add is that I will never have to have a stand alone EM system unless I want the ability to run more than one map. That is the ONLY thing I would gain though, the JECS ECU is capable of adjusting anything a stand alone can all be it not as easily done. Anything can be adjusted to any values you want it to be. Whether it be valve timing, AFR, whatever. So unless I get to the point where I am no longer streetable, or I need to run racing fuel to hit my goals, then I don't see me ever wanting an EM system.

Sounds expensive. Props for originality though.

I would give my left nut for that torque curve!

Just making sure one of my questions didn't possibly get lost in my posts.

Do we know of anywhere that could do some custom brakets and sliders to get my seats to fit here in Reno?

Maybe C&C could help you out there.
