Just got the new "sledgehammer". Dyno testing next week - looking for 500 RWHP, on the dynojet. Even I am not cocky enough to say 500 on the Mustang.....yet.

Any interested 951 guys more than welcome to come along and watch the dyno

I am looking forward to seeing this as well as all of the other well sorted Vitesse products

Cannot wait to see the results!

Looks interesting, but out of curiousity what's the cost difference between that and simply (sorta' tongue-in-cheek) going to a 16v head setup?

Holy crap, thats a massive valve. Any worries about high-rpm problems with the bigger (heavier?) valves? Can you run a stock cam with that? I imagine you could, but you probably wouldn't realize the ultimate benefits without a more agressive cam profile, would you?

Nice, one way or another, Very nice!

Now, make a ITB intake manifold John!

Jim,
You're crazy.

Can't wait to see the results!!
I'm curious to see how it changes the torque curve and spool up.
I'm thinking of getting his stage 1 big valve head.

I'd like to know specs to, that is of course, if they are public. You can see the porting and large valves. Looks like new valve springs and i would assume Ti valve retainers. You daring enough to mill it?
What kind of compression ratio are you running? I'm trying to decide if a 9.0:1 2.7 or 2.8 (sleeved with new cylinders, possible with deck plate) is possible, or a grenade. (20 psi, 91 octane water)Trying to plan my build right now. As a matter of fact, can I contact you with some questions?
You could convert the intake side to studs, i like my head a lot better that way, instead of messing with the gaskets and such. if you do that, dont put in the studs in front of the holes for the head studs, those three have to go in after the head is installed. If you want more info on that, let me know, i have specs and pics and whatnot, but it ain't hard.

I have a Lindsey stage 3 head (similarly huge valves) which I intend to use with a standard cam?! I'm told there is definately a good gain to be had in both performance and general feel (no experience yet myself) but certainly I expect you'd get even more from it with an aftermarket cam.

Cost?

How hard is it to change over to 16V head?

MR951

Dammit, now I've have that tune in my head all day *lol*.

special tool,
very nice. what cam are you running with that?

That is one big valve. What's the stock MM for the intake?
