95 Spyder on the Dyno

[Jimvr4]

SoCal 3S arranged a Dyno day down in Montclair CA. Three were dozens of 3S cars and a Supra and NSX. I had the opportunity to have my car checked on on their all wheel drive dyno. Here's the car strapped down and ready to run:



My car is running a BPU setup with an AVC-R boost controller set for 1.0 bar. K&N intake, stock exhaust, stock fuel system, stock turbos, and stock engine management. The car made 278 AWHP on the best of three runs. Taking drive train losses of 30% (very rough estimate), the car is making about 390 BHP at the flywheel:



I also ran logs using Evoscan for all three runs. Each run had about 25 counts of knock between 4800 and 6500 RPM. The injector duty cycle shows that the fuel system was maxed out so I really need to turn down the boost a little until the knock goes away. Either that or upgrade the fuel system with bigger injectors and fuel management.

You definitely need to turn the boost down. 25 is way way too high.

I probably would have pissed myself after seeing the 25 counts of knock.

Got any pics of the NSX?

I was going to say... those dyno sheets look like crap... then I read your knock counts. Great googily moogily!!! Definitely turn that boost down!! It looks like it's running really lean. Time for a fuel pump upgrade if you haven't already.

Ya, i dont see a 255 in his mod list, time to get a fuel pump upgrade. Great looking car, bet its a blast with the top down.

DO NOT damage that car!!!!!

(let the non Spyder guys do that....)

drivetrain loss is more like 18-20%.

Hey Jim, glad you had a great time at the event! It was great meeting you.

The NSX is owned by our beloved Jojo!

Here are some pics.

very nice! Ground Zero Performance will be doing an entire engine build and swap for me after Thanksgiving. Hans has a fully buillt long block for me and we'll be adding 550's, 16t turbos, fuel pump w/hard kit, fmic,and all the goodies that go along with it! Can't wait to see the numbers come back on this monster!!!!

Damn, I love NSX's! I don't blame him for moving on.
