Another AWD dyno in Sac (Driving Ambition) - Subaru Enthusiasts Car Club of the Sierras

knucklesplitter · 2009-05-13, 05:46 PM

Driving Ambition is near Rancho Cordova. They have a Dynapack AWD dyno. Shad comes from a IMSA/ CART/Honda/Acura racing background, but he wants to do more with Subarus. I am headed down there tomorrow (5/14) to help him with the Kaminari car (Ray Cunningham's). I will report back my impressions.

Good point...

Anyway, a very nice clean and professional shop. About 6 NSX's there, including one supercharged and one or two with turbos. Evidently people ship NSX's in from all over the country to have them prepped at this shop. Couple S2000's too including a supercharged one.

The dyno is a Dynapack and it is very portable. It only needs low-amp 120Vac service - simple plug-in anywhere, and water from a hose. Shad said he could bring it up here for a Saturday dyno day if there was enough interest. He is doing that in Grass Valley on Saturday for some club.

Didn't get around to much tuning because we spent a lot of time trying to get the Cobb software to do what we wanted and getting the AccessPort married to the car. Had to load the stock map back in (vs. the open source starter map) in order for the Cobb to marry up. The car did make 420awhp at 17psi on initial pulls. This dyno definitely reads much higher than a Mustang.

Going back on Tuesday to finish up.

Went back yesterday and got Ray's car finished on 91 octane. It has forged pistons, Cozzy heads, APS SR56 turbo, APS FMIC, KSTech 83mm CAI, TGV Deletes, PE 850cc injectors, 3" turbo-back exhaust. It did 450awhp on 91oct. at 20psi and 11:1afr. That dyno reads high, but this is still good power. The big injectors were hitting 90% duty cycle and power was still climbing at redline. Race gas tuning should add 50+whp. He is going to take it to Thunder Hill in 2 weeks and run 100-ish octane on the 91 tune for a margin of safety during its shakedown cruise. It is not street-registered.

I would keep it down to the 93-95 octane range if you're running the 91 map personally.

We will prolly mix 100 to get it to that range.

I used to top off a tank of 91oct with 5 gal of 100oct when I was running a 91 map at the track. That should be right around 94 effective octane.
