A little of this, a little of that....500+ pump again
John Brewer came in today from the great state of Tennessee for a re-tune after changing some parts on his car.
The last time he was in he had 1,000 cc injectors a standard AMS turbo kit with a normal GT35r and 5 bolt .63 a/r turbine housing, HKS cams on the car.
The car on 93 octane made 416 whp and 362 ft lbs.
The car on 110 octane made 528 whp with 479 ft lbs.
The car has a self built 2.3 liter engine in it
BR Race FMIC
HKS Twin power
AMS header/02 housing/downpipe
JDM style catback (not sure what brand it was)
AMS VSR intake
BR Stage 3 head
AEM EMS
The changes to the car since the last time he was here were the following:
BR 272 cams
HTA35R with the same 5 bolt .63 a/r turbine housing
Full Blown double pumper
5 bar map sensor
1200 cc injectors
BR dual stage boost controller
I tuned the car on 93 octane first. I started having problems with the car after having the car very close to being dialed in. The car was misfiring and would not rev. I thought at first it was a fuel pressure line blown off, a quick check of that showed that was fine. I then checked the fuel gauge and it showed the car had about 3/8th of a tank of fuel. As I was talking to John about the problem the car was having it quit running. It ran out of gas..........very odd. My conclusion is either the fuel pumps were not all the way down to the bottom of the tank or there was a problem with the float/sending unit. John is going to look into the problem later, more than likely a simple installation error.
Once we added some more gas the final pump gas pull was made and the put down 508 whp and 417 ft lbs of torque at 30 psi. Very impressive gain of 92 whp and 55 ft lbs of torque over the last time it was tuned here.
I did a race gas tune next and ran it as high as 38 psi. The top end power with the .63 housing and 35r wheel on a stroker didn't shine as nicely as the pump gas but still managed to make 557 whp and 486 ft lbs of torque. A 29 whp gain and 7 ft lb increase.
We then put up a few dyno charts against his for comparison and the low end power of the car is rediculous compared to some others we layed over it. It was a very interesting comparison actually. Power under the curve was just excellent on this car but sacrificed some uptop.
Here are the dyno sheets of the car now. Pump gas is run #1 and race gas was run #2.
