How does 785/711 with 22psi 11.8A/F and 21*..........on E85
That's conservative for E85
That's on a hot engine.
It's stroker 4.6 DOHC, cams ported heads with a 3.4 Whipple with a return style fuel system
2600 rpms to 6400rpm all above 600 ft/lbs and 1900 rpms of over 700 ft/lbs in that range.
Hp never dropped off.
It would make 800 on a cold engine

Nice daily driver, huh?:rock::rock:

thats nasty, how much more fuel do you have to add to even every thing out? i heard that you have to run it richer to make it work right?

Roughly 30%
This is a return system. The a/f was very flat before on the break in tune, so just added 28% across the board. We did bump the baseline fuel pressure to 50psi on the fuel pressure regulator. It was trending leaner at 5700.
Keep in mind, this is on winter fuel. It's actually E70 or so right now for cold start ease. It will have to be retuned for E85 once it switches over in April here.
It will also make a bit more HP on the summer with the same timing and should be able to run a degree more safely. At 11.8, the a/f is conservative. Mainly for slight differences in fuel quality out there.

It still shows up the same a/f on the wideband.

So what do you think I will be running with a built block and a 3.4 on 91 Bill? Curious what my weak factors will be at this stage. Build sounds badass!

I don't see much of a problem of meeting your goal with a 3.4. The best thing is that your IAT2 numbers will be lower and stay lower over the long run VS the KB. This guys numbers stayed low all afternoon tuning and the supercharger never got hot. The iron block did retain a lot of heat though. I took the car out for a test drive with the owner and the dang car is so much more nasty, it's totally unreal!
His next mod will be the Crusher with the slot MAF. As this car sits and at the same level of tune, I have no doubt that it would make over 830..............well over 830:rock:
