One question, you mentioned the AFR being good in the in car guage. Does this differ from what's shown on the dyno? I can't see clearly. A little clarification may help. Would be beneficial to know if the in car guage or dyno is more accurate to judge these kinds of things (for everyone).
First guy to break that 700 mark, correct?
Nik, good points but both IMG and I have been doing the VT3 in stages, not unlike what most companies do when they develop a product, we didn't start with high boost, but instead we have gradually been increasing it, so things need to be kept into context for each stage. This block is not sleeved, but it's absolutely strong enough to handle this boost level, as long as the tune is solid, and the octane level is sufficient. Now I can't run 91 only with this much boost, but the car made over 600whp on 91 only, you can't do that on a stock motor, so things need to be presented in context, not just what the the highest result is!
Fair question on the AFR, it's a little lean up top according to the sniffer, but it looks like the sniffer reads .5 - 1 leaner than my gauge does, which is pretty common. The car had a race gas blend, with a few gallons of E85 so you can run it a little leaner than you would with just pump. We did another run right after with an adjustment and made 699whp, with a little richer AFR. We'll look at the dyno's and adjust where need be but with the race gas I'm not as concerned as I would be if it was pump only.
I think I'm the second, IMG hit 709WHP.
