- any richer between 3700 and 5200, torque went down by some 10's of Nm - in fact, I think that we put the car on the dyno since the video, and have it at AFR 13, and that gained a bit of torque
- at Spa, we ran with a max boost pressure of 15-16 psi, and EGT values of around 1620 Fahrenheit.
- we did another run at Spa with around 30% Xylene added, and we could easily run 18 psi with similar EGT
Was this the data you were looking for?

What did you measure AFR on the dyno with?
MAx torque in a 951 At 13:1 runs contrary to 100's of my dyno runs and wideband datalogger.
I get max at 11.5-11.8.

That's interesting - when we tried going richer in that area, we actually lost some torque. Hmm.
Our issue is now that we can keep up with the earlier GT3's (just), but the later model (the ones with the 390-420+ engines) get away from us - on the straights, that is. If only there were a good and affordable supply of racing gas here... however, at around $30 per gallon, this becomes a serious buget factor for a racing weekend (I was completely jealous when I was over at Lagina, and saw they have a pump there with 106 at $7/gallon - is that what you call "pump gass"

We run in the "Racing" class, have great fun there, and prove that it does not take a GT3 to be quick around Spa (especially the double-lefthander called Pouhon, no P-car keeps up with our car's exit speed....).
Don't hesitate to ask further details of the car, and if you are planning on visiting the Porsche days, don't hesitate to swing by, and take a passenger ride with us - we like the 44, and together with Hans' efforts, we appear to have created some new enthousiasm for 944 racing in the Netherlands: there are plenty of S2's, 951's, 968's prepped for racing - and that's not even counting the 944 "basic" cup that is running very succesfully here.
Kind regards

Anyway that was some nice film footage of that car on the track! And I did go to your site, but it's not in English, and photos only get you so far!
And about the site being in Dutch - we'll be happy to offer you courses in one of the more important languages of the world, spoken by at least 20 million people in the world, namely Dutch - you will of course have to offer a ride in your car when it is finished!
kind regards
Ron
