Read a little on it last nite but really didn't find much. I was wondering if this cam is too much for a boost setup? I got these on a good deal brand new but forgot they were stage 2 and i really only seen people run the pro 1s in a boosted setup. If its too much what came should i run? Car should be a 750-800whp car imo.

 

Bump nobody?

 

This is one of those things that would warrant a hell of a lot more details about your setup. A lot of people would say Pro 1's only and others to mix and match Pro 1 and Pro 2 intake and exhaust. More about your setup is needed to go any further. And really at your power level you should know most of this already haha.

 

for a 700whp car, the pro2 st2 is ok

 

Go with the Pro 1's a lot of guys in SFWD have had great success. Can't beat it for the money.

 

Setup is a
Css 81mm b18a1
Wiesco 10:1 pistons
Manley turbo tuff rods
Acl race bearings
Oem main bolts
B16a head
Supertech springs 85lbs
Ferrea 6000 series valves
Skunk2 proseries stage 2 cams
T4 topmount
Dual 38s
Billet borg Warner s366
S300
1600cc fic injectors
Full race intake manifold
75mm tb
Arp head studs
Skunk2 cam gears
Ge 8an fuel rail
12gal fuel cell
A1000 fuel pump
8an feed and 8 return
Etc etc...

 

I already have pro 2s. That's why I'm trying to see if i need to ditch these and go with something different.

 

Try 'em out first at this point...

 

Yeah I'mthinking uunless someone else gives me reason not too.

 

stage 2 uses same lift and more duration than stage 1, so a 0.02 milling (CR 10.5:1) will help em to run better...

 

You think ill be fine running pro 2s?

 

yeah i think with your set up, they are ok...even without milling the head..

also i dont think they re gonna offer sg better than the stage 1, except little more power above 6000 rpms...

 

You guys keep using Pro and Stage series cams like the terms are interchangeable. For Pro series cams the "stage" is actually Pro 1+, Pro 2+, Pro 3+. For Tuner series cams the "stage" is actually Stage 1, Stage 2, Stage 3. So when you keep saying stage 2 are you talking Pro series like the original post or Tuner series like has been repeated on the second page?

I will assume you are still talking about the Pro 2+ cams since that is what the title says before Stage. Since you seem to be set on using them then try them out, I would say you are on the tipping point between Pro1's and Pro2's. Just be sure to take your time and get all relevant measurements to be able to adjust them quite a bit on the dyno to find the sweet spot for your setup.

 

you re right.

its just that pro1, pro2, etc nomenclature that is difficult to digest...

esspecialy when all other cam tuners use stages...

 

It's gonna take a shitload of work to hit your power on an 81mm motor.

 

And without a ported head it'll be even harder.

me personally I wouldn't run a CSS block at that power level. it's nothing more than a glorified block guard and the stock sleeves are a definite weak link.

do you want to destroy a nearly 20k dollar motor because you didn't spend a couple hundred more for a proper block?
I wouldn't trust stock anything at 800hp much less a stock sleeve. with the CSS process you'll no longer crack the top of the sleeve, you'll blow out the center of the sleeve and destroy everything.

 

SpeedFactory is using Pro2's in James car right now. That is my understanding. I have no experience personally, but that is a lot of cam for an 81mm setup and stock ports.

 

I hear you. Ill have to see how it goes. If i can't find the time to put the car together by next month i might just wait until winter time, save cash and do a Benson or ge sleeved block. I honestly do trust the css process though for some reason.

 

It's been gasket matched. Runners and stuff is smooth but not race race stuff.
