skunk2 pro2's in boost

[Grunny]

Anyone running skunk2 pro2's in there boost setup. Just curious cuz i have a set in my built lsv and plans have changed goin for boost, but im unsure if the cams have to much duration and valve over lap. Post up ur setup if your running them. Other wise i might sell my cams for some pro1's or itr and ctr setup.

[hanson12b]

I obviously am not running them but I heard they work really well with a boosted application. I think it all depends on the tuning

[hanson12b]

And if they will work in a b16a i might be interested lol

[SlowEGG]

They are too big for a stock compression b16. They'd work good for your boosted setup nate(slowcivic) is using them in his car with great results.

[Grunny]

if its a stock b16 there goin to be to big, bump your compression up then run them.

[SlowEGG]

Obviously tuning is key here.

i saw that nate is runnin them but im not goin that crazy with my setup this year only running 8 to 10 lbs, but my setup is kind of diffrent i takin my all motor lsv and boostin it, hence why im running low boost.

My question should be, are pro2's goin to hurt my setup more than improve it.

[hanson12b]

Well damn, im not touching the pistons other than rings this year, just getting the head built

So you're gonna boost your high comp setup? To be honest I think you'll be fine. If I recall correctly he saw gains everywhere.

[Grunny]

my comp is about 12 to 1 so not to high. Just tryin out a diffrent style. I think im just gunna run them and see what happens on the dyno if i dont like the numbers ill change the cams

[AlexD]

Its like I was telling ya earlier, these cams are aggressive and good for boost with the right application.

I believe because of the backpressure theyll generate, the shorter runners of log manifolds will hinder the performance theyll give you.

To fully utilize these cams an equal length manifold would be preferable, like what nate is running (custom sidewinder i believe). Ram horns, top mounts and sidewinders will help bring out the full potential of those cams in a boosted setup.

[Grunny]

i would rather change me cams then change me manifold i want to keep my full rad

[AlexD]

youll get good money for them, just go with ITR, proven over and over again to do great for boost.

[Grunny]

I would like to c what kind of number my setup makes first

[AlexD]

youll hit your goal no problem with stock b16 cams and E85

[Grunny]

ya and i have a set of those in my box so i can alwasy swap them but if i was gunne change cams i would get a set of pro 1's or itr/ctr setup

x2!!

[Grunny]

probly just gunna dyno it and see what happens

[Whispering Eye]

cams are too big for your setup IMO

[Grunny]

c thats what i was thinkin. I put these in and never drove the car kinda wish i would have

[Whispering Eye]

lol i may be intrested.

[jdm91teg]

sorry to budge in on your thread but does anyone know what would be better for my stock b16a boosted. my head is composed of supertech valve stem seals and guides and port n polish and 3 angle with arp blox intake mani with hondata intake mani gasket. i was thinking 8-12lbs at most prob just 10...

[SlowEGG]

Pro 2s are supposed to be used with atleast 12:1 on an all motor setup. I'm almost positive this will help more than hurt.

[Grunny]

why did nate see such a gain over the turbo cams

[SlowEGG]

I couldn't give you a solid explanation because I really dont know. I don't even want to guess lol. But its been proven that N/A cams make power on turbo builds. Maybe due to boost upping the dynamic compression ratio thus yielding enough comp to justify the power? :lolhit: I really don't know. I'd rather see you try as opposed to swapping them out never knowing how well they may or may not have worked. You should still figure your car is still an all motor car with a turbo stuck to it.

[Grunny]

I like the way you think im gunna run them and see what kind of number i produce if they hold me back then ill change them put until then the head stays the way it is.

[SlowEGG]

and you shouldn't have a problem unloading those things. Pro2's sell like hot cakes lol

[Grunny]

im just not sure what cam i would go with if i dont run these

[SlowEGG]

itr's? how much power are you looking for?

[Grunny]

on this block im only goin to run 8 to 10 lbs so what ever number that produces ill live with and next winter im gunna build a diffrent block

[AlexD]

pro 2's are overkill for this setup, go stock or itr, will be perfect.

"N/A" cams don't create back pressure. They would have increased over lap over a stock cam. This is why you could see negative results when using a poor flowing manifold design like a log. As the increased back pressure form the manifold/turbo would be pushing back into the chambers. ( hint: diesel guys go on and on about drive pressure and there want for 1:1 pressure ratio.) This explains how pressure in the exhaust manifold is directly related to over lap and cam selection. So by going to a very free flowing manifold/turbine allows the use of very large cams.

Most if not all "turbo" cams were designed back when there were crap 8v or 12v factory turbo cars running around. It wasn't until just a few years ago that people started trying to use n/a cams and surprisingly they worked well when you didn't have a cyl head i could out flow by blowing through a straw.:scared:

Very knowledgeable post, sir. I will be sure to direct all inquires to your private messaging box, so that I may have the proper answer.

i see, thanks for clearing that up

[slowcivic]

I think I've said this a few times but pro2s are the baddest bitch for the price!!!!!

[Grunny]

im in no rush to sell i kinda wana run them just to see how they do if they sell they sell.
