No, we make them for both the P11 and the P12/20V.

.................
Maybe you can help me with this question. What valve springs do you run with the P11 head for turbo? 115? or 138? I remember a few years ago Mazworxs warned about using the 138's because they were showing abnormal wear on the cams? I just don't want to spit a shim out if I bounce off the limiter @9k with N1 cams.

The Factory P11 springs are actually stiffer than the P12 springs. Cam profiles, particularly ramp profiles play a large role in what spring rates are necessary too. This page has a list of valve spring seat pressures. http://pulsar.org.au/forums/showthre...l-advise/page3

I assume some of you guys are using aftermarket throttle bodies. Are any of you guys using the one Mazworx provides or a different brand?

I have a q45 90mm one, but I'd love to have a ross or something that was cleaner and shinier.

kind of off topic but i figure this is where the guys with the most power hang out so would be the best place to ask
is the comp clutch white bunny 6 puck good for 400ish whp? or is there anything better out there in the same price range?

I preferred the RPS Max Street clutch. You can get it in a 6puck, I ran it with a full face disk at 360whp. Multiple passes at the drag strip, 30k miles of daily abuse. Sold it with plenty of life left on it.

Don't get the stiffest Supertechs, you will destroy shims.

The Sr20/Sr22vet thread
Without almost any details about your setup, I'm guessing you don't have one quite yet so I'll just say that the motor can easily hold 1.3 bar from a EFR7670...or at least mine and everyone else's in here can which really doesn't mean anything.

Would be happy to put, say, 450hp to 500hp Currently running on stock turbo at the moment, looking to upgrade to a 7670, hence I'm asking around. Thank you for your time! |

The Sr20/Sr22vet thread
Yeah, then just depending on how high the dyno you use reads, you should be able to make between 450-500. As for the boost control strategy, I guess it depends on how simple or complex you want to be, but if you put a 1.3bar spring in, you're keeping things simple as long as the WG is plumbed effectively.

I've been keeping an eye on the build threads and this one and I'm starting up my first vet build. I'm looking to make a car to have fun with on the streets as far as some racing. My question is that I'm going to sleeve the block 9:1 87mm full supertech valve train on e85 1200cc injectors. Is that power goal realistic without having to increase the stoke of the bottom end with the right turbo/manifold set up?

When it comes to sleeving blocks power level is only one thing to consider, another is what the engine will be used for. For example, someone who's building a 300hp weekend toy would be fine on stock sleeves vs an engine that's being built specifically for road course racing where you see a lot more heat cycling for that I'd definitely recommend to sleeve, even if it's only for 300hp.

Great info to know ahead of time about the injectors. I'm curious about your dyno numbers on your setup since I'm going for a really similar build as yours. Is your turbo just about maxing out already?

It comes from the cylinders being thin and having lots of heat thrown at them.

7163 owner here. P12 head with N1 cams. 404whp/338ftlbs at only 20psi and 6500rpm on a Mustang Dyno. Was blowing out spark anywhere above that. Have since put in IGN-1A coils and going back for 25-30psi/8-9k. Should pull 500whp/400ftlbs no prob and spools great with the mixed flow TiAl wheel.

I'm running a 7670 twin scroll on my 2.2 vvl with n1 cams. Making around 360whp on 14 psi. Need to switch out to a high boost actuator. I am liking the response so far.

From what I am seeing, I am going to forgo the P12 and go straight to N1 cams on my setup |

Just keep in mind the N1s have a lot of overlap which becomes a problem with large backpressure and a 2.2 is going to generate more backpressure than a 2.0 assuming everything else is the same. I'm actually concerned a bit that the N1s are going to limit me when I shoot for 30psi. I may adjust the cams to reduce the overlap a bit.
