The sole completed car was sold to an American collector and two more were constructed for two prominent Ferrari clients. All three cars were sold under the condition that they were never to be raced in anger. Three further tubs were constructed, but according to Ferrari these were later destroyed."

And as for me, I need to post more so I can catch up to you. It make take me 20 years, but I'll catch up.

Hope that wasn’t too technical.

No - the ONLY time you get tire slippage on the dyno is when you WANT it - to show off, by not properly tightening the straps.
This has happened to me at only 500 FT/LBS torque - we simply re-tightened.
That ex-vit-termini-verga guy loves to pull this stunt with the Skylines to impress all the Honda children.

Ooopps, I screwed up. John Carmack's F40 is only lightly modded. I was thinking of his Testarossa when I posted that. His Testarossa was Norwood built and puts out 1000rwhp.
Regardless of what anyone says, that F40 is most definitely not stock.
Hey Tool, so now you are talking down about the Exvitermini guy??? The guy ran a best of 8.27 at 162mph in the 1/4mi and makes ~1350hp plus there are vids on his website to prove what it does. He has done and accomplished more with his drivetrain then you have or ever will, so have some respect and don't talk about him like he's a scam artist.
Rolex, the F50 GT1 was created to run in the '95-'96 Lemans, however Ferrari ended the program before it begun, and after the cars had been built. From what I remember, I think one of the 3 was totalled and only 2 remain in existence.

You've missed my point again, son.
I am trying to figure out if you are shallow, or obtuse.
I am not really fond of you to begin with. We ALL know that you bought Joe's Vitesse turbo STRICTLY to publicize the specs to get attention - just like something a little boy would do.
And you had the ***** to complain when you couldn't sell it.
Why don't YOU PESONALLY accomplish something with your own car????
Instead of riding everyone's nut sack, boy.

Finally, you have no clue idea what you are talking about with the GT1. Sorry, wrong! It was never designed to go to LeMans. Ferrari was sticking with IMSA GTP, they werent going to go into WSC in Eurpoe. You clearly didn't read that detailed explanation I gave above, sorry Charlie.

Dude,you are getting in trouble, don't you know that pukephile and losermagnifico are the rennlist dynamic duo.

All of what you said is OT and has nothing to do with this post, so just let it go. Lets just agree to disagree and leave it at that. The tone of your post gave me the impression that you were considering the Exvitermini guy or his car to be a joke or ricer, etc etc which couldn't be farther from the truth. If I misunderstood, I apologize, but that's the way it sounded.
I'm trying to accomplish something with my car, though it's tough juggling 2 project cars (trying to fully build both at the same time) and a job that takes 150% of my time. I just purchased a Gt35r from Tim @ SFR, so I'm headed in the right direction.
Rolex, I didn't read your post before posting myself. You're right about the Gt1. I was basing my info off of some, now obviously, ill-informed websites. I entirely agree about the Norwood stuff. I've heard alot of horror stories. John Carmack has a Blog and he's even complained numerous times about how much trouble he's had with Norwood and keeping his cars together. I never said they were God's gift or anything.
Lart, you b@stard!

When it comes to auto manufacturers, there is also the question of sampling techniques (which cars to select).
SAE has recognized all of this and has come up with a Power Certification program with associated standards, mentioned here: http://www.sae.org/certifiedpower/details.htm
To answer your question which gear to use, then it is true that it does make a difference (if the resistance on the dyno isn’t adjusted for gear used) especially on our cars with a turbo lag.
For our cars 4th gear seems to be high enough to prevent slipping (except at very high torque). 5th gear could be used with the same or maybe slightly better results, but the dyno equipment will be spinning pretty fast, lots of stored energy, which in case of failure could be quite nasty.
As ST mentioned strapping the car down can eliminate slippage. For that purpose there should really be vertical straps, since the vertical force component is the one needed.
Judged by the rear end lift of the F40, there was not much of a vertical tie-down on that car, hence the need for a higher gear.
Laust
PS As to being technical: Throwing complicated formulae around will not help on the pitfalls above.

Good luck with the turbo from Tim too. He is an "awesome" fabricator and is currently making my Stage 2 968 Headers and SFR Intake too.
