Im hoping 750cc will do part of the trick. Im hoping for mid 300s till I get the other items done...

 

off the wall question but boost can only be turned up and held at that boost level as good as its boost controller & w/g spring? can a manual boost controller do the trick or does it have to be electronic?

 

i used a manual on my setup, it works fine. its recommended that u only double the WG spring. so if your boosting 20psi, try to get a hold of at least a 10psi spring....not sure what your running now? or are u running no boost controller just the WG spring right now?

 

right now I have a tial w/g 35mm , 7psi spring. I do have a manual boost controller from hanh racecraft I think? were did you get your 10 psi spring from?

 

yeah i wouldnt push 20psi on the 7psi spring, any tial dealer should be able to get u a spring for your WG. many shops keep them in stock if they do a lot of tuning. when i got my car tuned we messed around with a few different springs.

 

so holding 18psi depends on the boost controller? Probably better to upgrade the wastegate spring?

 

What turbo are you running?

My setup:

9:1 wiseco pistons
Eagle Rods
Edelbrock victor X intake manifold
stock throttle body
Full race exhaust manifold
Turbonetics T3/T4 62-1
3"DP
3" cold side piping
2.5" hot side piping
Dynoed at 353whp and 254ft trq on 12 psi and LS tranny (LS tranny blew after Dyno )

 

what does your post have anything to do with what he needs to make 400whp? not to mention he already said what turbo hes running.

 

glad you caught that. hey I take it with that set-up its drag car?

 

daily driven, will be getting some track time in the spring, didnt get a chance to get it out this season since i just finished it.

 

holy *****!!! that thing must be a monster from light to light & worse on the highway! And I'm only looking for your TQ numbers as my HP!!!

 

HAHA light to light not so much but on the highway definately a monster. not much traction first 3 gears
