I am going single, maybe the gt35/40. My motor was rebuilt about 5k miles ago and is running great.

Should I pull the motor and have it street ported now, or wait until I put some miles on the engine with the single?

 

wait

 

Agreed,

wait

 

wait

 

Thanks for the response everyone. I'll wait. I'm ordering my injectors,fuel pump and hoses now....Step #1!

 

FYI:

My car has a stock motor, XS T04S, PFC and 1300 Sec and made 361RWHP @ 14 PSI

A friend of mine has a KD streetport, XS T04S, PFC and 1600Sec and made 362RWHP @14psi

Both were tuned by XS and KD Rotary....Just wait! These isnt a big difference here...

 

I am definitely excited to add another 80 - 100 HP, no doubt.

 

no comment to rotary93

 

I think thats pretty Damn good!

 

VOSKO - Why? do you disagree? or are you the one with the streetport and same hp #'s?

 

umm i have a different turbo, different porting, different engine management. i'm just saying if two guys one ported and one with stock engine get the same #'s almost that must mean something is up with the porting.......unless there is something wrong with the ported car who knows???? know rotary93 and the other guy

 

Does the lack of porting add stress to the motor at higher rpm? or just limit the amount of boost you can run? or both.

 

Anything that adds more power is going to cause more stress, not just on the engine but the drivetrain. So to answer your question, no it just limits air flow. Honestly in most cases the turbo is a much bigger air restriction than the ports. I personnaly have never seen a case where porting alone caused a significant HP difference especially on a turbo engine.

 

with a street port should see more than 1rwhp gain. supposed to get 10%.......

 

10% sounds more like it. Obviously, the comparison before that netted 1 rwhp difference had many variables that could have made a huge difference (tuning, fuel, air temps, etc.).

All I know is I need to close a few more deals so I can buy my turbo!!!!

 

there are many variables but two cars from the same tuner.....
