Car = 92 Civic DX
Motor = USDM GSR, freshly rebuilt
Kit = Peakboost kit
Injectors = 550cc
MAP sensor = 2.5 bar Motorola MPX4250A
Mangement = Crome, tuned by me.
Boost controller = Greddy Profec B spec 2



The early torque peak was due to the gain being set a little too high - was spiking to ~12.8psi before settling down to 10.8-11.1psi for the remainder of the run. Ran out of time on the dyno, but turned it down a couple percent and checked that it stopped spiking on the street. Car drives awesome. High 10s/low 11s AFRs at full boost, 93 octane pump gas.

The owner, Nichole was pretty happy to have the car done. The first motor in it got killed my a MBC malfunction, and she was really relucatant to push this one hard. She'd done almost all the work aside from tuning on the car herself, and deserves mad props for that.

 

Very nice man.

She gets mad props from me.

 

nice numbers, on a mustang dyno!

email us or give me a call monday morning with yours and the customers shipping info, so we can get you some of the new PeakBoost t-shirts that just came in!

Nice man....good to see a little bit of cincy representation. Isn't high 10's AFR a tad bit too rich though??

 

nice work Dave... :thumbup That cars def gonna rip.

 

y so rich blundar? high 10's/low11s a/f ratio?

I'm guessing he tuned it very conservative since he said she was worried cause the last motor went pop. Still, running rich it still made 303 on 11 psi.

bingo. 303 on a mustang dyno really isn't too shabby.

I'd rather crank up the boost to 11psi and run 10.8-11.2 AFRs at full boost than run a more aggressive 12-12.5:1 AFR timing ridden tune at 8 or 9 psi to make the same power. The last motor went kaboom in a very big way, and I wasn't willing to see the same thing happen to this one. Plus, it's a daily driver. Plus it's going to spend essentially its whole life on pump gas, not race gas. Plus it's a stock bottom end (with ARP headstuds). Plus with it rich, the IAT correction won't make things dangerous. Car was good for probably another 10-15 whp at this level with nothing except more aggressive tuning - hell, just raising the revlimiter above 8250 would increase horsepower, but who wants to do that with a stock GSR valvetrain?

I'm chicken. I'll admit it.

 

its not being chicken, its being smart, and caring about peoples stuff. good looking out

 

nice...

 

i'm surprised you trust a profec b over a manual boost controller.

i wouldn't trust a profec b on any motor i cared about...

 

Nice work dave
Sounds like the owner is gonna have plenty of fun driving it.

Honestly, I've had really good luck with the Profec Bs... Take a little playing with to get the spikes to go away, but it worked awesome once dialed in. 11% set, 21% gain, 75 set gain I think with a 7psi spring...

I had a boostcut on the motor around 1psi above target boost anyways so if it acted up, we just hit the boost cut.

 

Nice stuff

 

Great job.
-PHiZ

 

Peakboost and crome

 

Chicks that work on their own cars rock
Those are some pretty good #'s too

 

good job dave
glad to see another happy customer with a PGMFI tune and making decent power

 

Awsesome...

 

Very nice. Mad props

 

awesome

 

any 1/4 mile times yet?

imagine the #'s on a dynojet
