Hey guys... pretty familiar with ls1's I've had one for years, but i'm pretty retarded when it comes to the boosted world of ls1's. Anyways, I have an 01 c5 with 1-7/8 long tubes and a fast 90mm. I scored a good deal on a used a&a head unit (v2 t trim) and brackets (8 rib). I also just scored a cold side kit with the front mount ram air intercooler. Now, heres where my questions come into play.

Goals for the car :: I want around 550whp or under ( to keep the motor from blowing right away)

Question 1: What pulley size should I get to obtain that power goal (my kit came with a 3.125 which is wayyy to small. I'm figuring a 4" should do the trick and give me around 8-9 psi... any suggestions?!

Question 2: I have 60 lb injectors, I need to do a fuel pump. I'm figuring a walbro 340 lph with racetronix hot wiring kit. A) Will this support around 600+ to the tire B) Any problems with this kit ( I have read some installation problems and read that it wasnt any better then the walbro 225 c) I've read a different couple versions of this pump, which one would I need... PARTS NUMBERS PLEASE

Question 3:: I've got a friend that bought a d1 for his camaro and said he needed the ATI damper. ( i have no idea what these even do) but i do know I need a crank pin kit. Do I NEEED a damper? and if so, which one the ATI super damper?


Anyways... I have a mess of questions on here, hopefully I can get a help with a few of them, thanks guys!

 

1. 3.8 is the biggest 8 rib a&a sells. I would run the 3.8
3. Yes you need to pin the crank and you need a 8 rib balancer the best is innovators west. You also need 8 rib ps, alt, idler pulley or direct drive

 

Why is Innovators West better than ATI?

 

Hmm.. So what makes it an 8 rib kit that I bought?! I know it comes with brackets n some tensioner pulleys n such.. So what you're saying is I need a new power steering pulley, alternator pulley and crank pulley (ati damper)?!

 

On Corvettes stock all the pullies are 6 rib. So everything you don't have will need to get converted to 8 rib unless you run a direct drive/flip drive/secondary drive
