Hi fellas,
My build finally finished and the RB25/30 block will be in the car in a few days. I will be running:
1) GT35R 0.86 A/R with Tial 38mm external waste gate
2)256 inlet 264 exhaust cams with adjustable gears,
3) plazmaman plennum,
4) 3.5" turbo back exhaust with high flow cat
5) power FC
+ all the other usual mods I.e. front mount, 040 fuel pump, 555 nismo injectors etc etc.
Anyways, I know that my power output should be around the 350 - 370 rwkw. Now, I know screamer pipes don't make any difference under 250 rwkw if the exhaust is not restricted.
However, with around 360 rwkw, I am begining to think that if I have the screamer plumbed into the exhaust, it will restrict it alot.
I am not in it for the sound, actually, I think it sounds quite shit, but anyway, thats my opinion. However, if I am going to lose power by not having a screamer, I think I will put it on.
I need some opinions from people in this power range or people that have had experience with such things, screamer or no screamer? WIll I lose power if I plumb it back at this power range with a 3.5" straight through exhaust with a high flow cat?????
Cheers fellas!
