I won't be doing most of this 'til the spring (gotta save up some cash first), but what do you guys seriously think about this setup? Both in terms of how much power it might make and the overall "goodness" of it. All thoughts/comments welcome.

Ported Head
78lb Valve Springs
Valves

Ported M62
Ported Throttle-body

2.7" or 2.8" pulley (haven't decided yet)
60lb Injectors

H/E
Dual Pass w/ Option B

Spec Stage 2+ Clutch
Fidenza Flywheel

Tune

I currently have the Vibrant header/dp with the GMPP Performance exhaust, but I would upgrade to (probably) the Hahn 3" catback or CTI 3" catback.

 

3" is overkill. Stick with 2.5" all the way back. And if you go with a 2.7 u'll prob need meth.

 

Yea that's why I'm thinking I'll probably go with the 2.8" for now, I don't want to run meth right now because I don't feel like having to always watch it and fill it, I want to be able to go and not worry about it. Although it is awesome

 

just go 2.7 no need to go 2.8 then say oh i want 2.7 later...it will happen

and you don't need meth for it

 

i love meth

 

Yea I was thinking with dual pass/option B and if I get ZZP's stage 3 h/e I probably would be okay with a 2.7" on there.

 

Ross, run the hub, youll be okay

 

A little 2.7 action?

 

i did when i had the m62 still on there, no biggie, a little meth and h/e she was golden

 

i ran 60's and a 2.7 for awhile, and I was fine. Just a h/e and i was good.

 

Good to know guys. What were your IAT2's at?

Btw, Glen, put your car back in your sig, it's one of my fav's on here.

 

skip 60, go 80lbs on a 2.7 tuned on e85

 

I would love to run E85, but NJ is lacking

 

I agree. Then you dont have to run meth

 

damn. the heb 5 mins from me got it

yep true

 

x3

 

Skip these things.

Valves, Ported M62, Ported Throttle-body

The stock valves are fine as is, there really isn't much of a reason to waste money on getting the supercharger ported, if you want more power from the TB area go with the ls4 throttle body. Also the 3 inch exhaust is a good idea because it will lower your boost, I also recommend the 2.8 pulley so your not over spinning the blower.

 

Thoughts on valve springs everyone?

 

nice set up there ross but i do hope u r gonna get some meth later

 

Valve springs aren't necessarily a bad idea, but the question is whether or not they are worth it.

Some people will argue that stock valve springs are good to 7500 rpms, I personally think they are 100% stable up to 7200 rpms and that they can run up to 7400 rpm without to to much abuse being taken. So the question is whether or not a few hundred rpm's more is worth the extra money. Staying in your power band longer is a great thing, but with stock cams your not going to keep producing power all the way up to 8 grand. However the longer you are in your power band the better. All in all valve springs are great, it's just whether or not they are worth it for you.

 

never knew what my IAT's were cause I never had a wideband. I tried to datalog with a buddie's copy of HPT, but I just couldn't get it to work. All I can give you is the numbers that ZZP has for their "stg 2 h/e", since that's what I was running.

As for valve springs, the OEM's are good. If you're thinking about porting the s/c, you should consider porting the intake manifold as well. Just make sure you know what you're doing, or take it to someone that knows what they're doing. A guy from this forum (i think it's ebristol) does pretty good job.
