AF: 12-13
Tuner: Bubba

 

Nice Is the exhaust 3" all the way back? It's a pretty smooth curve you have there.

 

3in all the way back but the muffler is 2 1/2 ..ill be changing it this weekend and geting it tuned on c16

 

Just came back from the dyno and made 553 whp @25 psi with a new gt35r turbo on c16..

have some kinda of boost leak at peak power,losing boost pressure
checked everthing and it all seems find..

 

thats cool PV = nRT is chemistry for you. Just learned it this Year

 

Nice numbers. That's a bit lean though, I would ask him to richen it up a bit.

 

u sure he tuned it to 12-13A/F? i highly doubt that.


that turbo is huge. pretty laggy. turn the boost up and see what that turbo can really do.

i made the exact same power at 10 psi on my GT35R. good numbers, but turn up that boost!

 

how much bigger are the 62-1's compared to the 35R's w/ 63ar?

in for the 35r dyno chart. i want to see how it spools in comparison to that 62-1 on that setup.

how much was boost dropping off?

 

NICE numbers!

Exactly.

 

with your boost drop off, how are you regulating boost? manual boost controller on dyno?

 

im very impressed with my stock bottom end GSR @10psi making 285/225......but i have traction issues with my stock open diff, i wouldnt wanna make any more power at this point....i cant hook up until i get a closed diff

for a very laggy turbo and 12-13 A/F is not to safe.

 

leaner is meaner but ask bubba to make it a lil safer, somewhere like mid to high 11-12, i know with mine he made it really rich, but it was a stock motor, so i can see why, g00d numbers bubba is a good tuner
