Thread: Big turbo and HP guys (cam related)

Hi

I just one a little review on what cams and turbos (boost if you can ) are you using
I got pretty much and idea on what cam Im going to get..but more opinions would be great.
Thanks.

from what ive personally read, all hail the s4's for turbo, although i run them in my NA application they still make good power over stock

^^ True Fred Casey run S4's in his low 10's SER.

tomei cams are the what the big boys run like Mazworx in there s14. For a t3 turbo S4s will work out great but a 280* cam will help out too. What is your set up?

^^^yup, have to agree, and the biggest reason why people use S4's is because you dont have to change the valvesprings and retainers. HKS stage 3s, tomei's, BC stage 3's, JWT C series, are all the big cams for big turbos and/or ported heads.

S4s and call it a day

I am pretty sure he is going to like 500+ HP. So BIG turbo cams but I think he wants a list of what you used along with Horsepower made.

I've heard the stock sr cams don't become much of a restriction till over 400whp. I know they make gains but there was someone on the old forum that made over 500 on stock cams...

Big duration cams are great, but you don't need them for turbo. A 12.5mm lift cam with 270* duration is overkill for most goals.

62mm turbo 1,15 turbine housing with a 67mm exducer wheel .
Im planing to rev to 8000 rpm I was thinking jwt c2 ( 7750 now) my power band its over 450whp from 6000 rpm to 7750.
Back pressure its lower than boost right now
Im on stock cams Coheed with my turbo setup at 25 lbs Im getting pretty much 500 whp , my last dyno was at 23 lbs adn 470+whp.
S4 will do the job right I know that but I like to try somethig different
I think Andreas can help me here he have been building high hp car for a long time...9 sec car etc.
thanks for your opinions guys .

Invest in a standalone and you'll make the power you want. ie. aem, megasquirt, big stuff.
