your only 7hp off the mark of 240 so I would say your running good it might just be elevation........if you really want more power($$$$) there are things you could do, but from what I read you are happy with the cars current setup? sounds like a fun ride :D

Where do I get that, and how does it fit?

Well 1st, sell the WRX and buy a 5.0L Mustang. :lol:

Then call Ramsey Raceing Engineering at (813)885-5913 and get a gigantor turbo and what looks like completely custom fabed intake manifold and exhaust headers, as well as several thousand dollars worth of supporting parts. :lol:

I just realized that thing's got dual blow off valves and no intercooler. :shock: That must be an insane drag motor!

I was totally gonna say that... :lol:

Is that dyno tuned? If so, you can't write it off to altitude or gas (although Reno gas is the same as Bay Area gas anyway). And I never said it wasn't fast. ;) It's quite possible that your car is just slightly knock prone at high RPMs. What spark plugs are you using, and how many miles did they have when you dyno'd? What was the gap?

I was joking. It is plenty fast for me. Yes that was dyno tuned by Shiv. I think you are correct though. I never even thought of the plugs (duh!). They were the stock plugs, I never checked the gap. The car had about 8,000 miles on it when it was dyno tuned. Shiv commented that some cars are just knock prone. He made no mention of changing plugs, but that is certainly worth a try and another dyno tune. My car has been acting a little odd at highway speeds, so I may be going back to Vishnu this summer anyways. At WOT the boost oscilates (sp?) between 12-14 psi. It is not noticeable in lower gears, but in 4th you can feel the power fluctuate. I'll post a new topic on that subject and see if anyone else has the similar issue.

It's detecting knock (or you have a bad boost solenoid). The correct plugs may indeed correct the probl;em. Otherwise, Shiv is likely right in that you either have a knock-prone car, or it thinks it's detecting knock, which has the same effect. :)

I am hopefully going to S-Squared on Saturday. Nate is going to have a look and dyno tune. I hope it is not a knock prone car. We are going to try the new plugs.

Hey Ban Suvs, thanks for sending me (at least I think you did) to S-Squared. I just got back. Spent a few hours on the dyno. Nate fixed the problem. He had to re-flash, but man what a difference. The power delivery is smoother than ever. My car ran 230.4 whp @ 7000 rpm and 213.5 Ft-lbs @ 4750 on the Mustang Dyno. The car pulls so much harder at higher speeds now. I must say, I am very impressed with their shop and staff. So what is my car now? An S-Squared stage 2?

They gave me plenty of suggustions for more power...he he he.

Dean, if you want to update my numbers and dyno, feel free.

Glad it worked out for you. I'm not sure if it was me primarily that got you into the shop, but I'm glad you did. Nate's going to be doing most of the work on my turbo conversion, whenever I get around to it. :)

Just returned from s-squared
 

I saw this post a week or two back, and now that I have some numbers I thought I'd thow 'em up. I'm actually pretty happy with them, although, with injectors I could do a lot better.

Mods: k&n intake, BPM uppipe, MRT turboback, VF30@14.5 psi

Before ecutek: 189.3 whp@6000 173.6 ft-lb@4750
After ecutek: 220.8 whp@6750 190.8 ft-lb@5500

I'm pretty happy about my before and after numbers.

I wonder what 18 psi would be like....

Re: Just returned from s-squared
 

Before and After numbers are great...

If you want them added to the first post, please provide the following information...

Name:
Car: (Yr Model)
Mods: (Power Mods)
Wheel HP: (XXX) @ (YYYY) RPM
Wheel Torque: (TTT) @ (ZZZZ) RPM
Dyno: (type @ Company Date Time)

Please specify if any changes other than flash from before to after.

See the first post for examples.

Thanks

OK, correctly formatted this time:

---Before Ecutek---

Wheel Torque: (173.6) @ (4750) RPM

---After Ecutek---
Wheel HP: (220.8) @ (6750) RPM
Wheel Torque: (190.8) @ (5500) RPM

Dyno: (Mustang @ s-squared 6/1/04)

Wow! Great Numbers.

Great... Any idea what peak or target boost before and after was, and I'll put that in as well.

those are some nice gains Congrats!
:shock: :D

Well I was running stock boost before (maybe a hair less) the reflash, and 14.5 psi after.

See you all at Reno Fernley

Was this the same map you had in at Cobb? If not, can you describe what was different?

Yes, it is the same map. When I got home, I compared the two graphs. On my cobb printout it has stock vs the modified version. The stock version has a lot of bumps and dips in the torque curve, but the modified version is a lot smoother and flatter, and the torque comes on a lot earlier.

When I look at the s-squared printout, the shape of the torque curve has gone back to be the same as the stock one. I am guessing that the ECU has relearned itself back into the old shape or something. I am quite happy with my max Hp number, but I think I could use more torque across the middle of the rpm range. Scott's car, which admittedly has a lot more modifications than mine and did spend 5 hours on a dyno being tuned, made 20+ ft-lbs of torque more that mine right across the midrange. I wonder if the off the shelf cobb map is not exactly right for my car, I might need a custom map. Unfortunately I don't want to spend anymore money on it, plus now that I have gone down the accessport road I would probably have to go back to utah to get it done :(

How is this possible? As someone that is waiting for their cobb accessport and is looking forward to it's benefits, I am alarmed by this report.
