Yes Cab,I do but don't use it yet. I have an MSD programmable so my timing curve I set manually,,,,,for now.When I get on a chassis dyno where I can see it at work then I will mix it in.Still trying to keep it simple 'till a get a good grip!

[quote=camastomcat]2 questions; 1 where is the burn on the ground strap, I can't see it in the picture 2 if it is really reading 11.7 on A/F, that's way rich Can I see inside the plug on the porcelain towards the bottom with a flashlight? [/quote The above screenshot is going over the stripe.I am still experimenting with the 2nd gear RPM as it comes so fast I have been over 7500 I need to verify my O/2 is reading properly.Over the weekend We will check it in another car with a Big Stuff 3 to see if the calibration is off.I'm buying 2 new ones anyway but want to know where I am! This vid shows plugs from several passes. https://www.youtube.com/watch?v=NwN1Ra8fb3c

camastomcat,This car is mostly street driven with 4 lbs of boost burning pump gas.E85 is great but not available everywhere so besides needing a 20 or 25 gallon cell I would need to carry a few 5 gal gas cans.E85 also has it's limits of octane requirement. I a believing more and more it was just poor weather and the tune was off.It came off the hit pretty good,,,,jsta didn't have the top end charge I'm used to.

Itis, Honestly, from my recollection of that day, at the hit, your car seemed a little stressed out as far as RPM's. You just might be going through the converter as mentioned above. The car almost sounded Funny car-ish as far as RPM's. Also, remember the weather was a bit sticky and no oxygen even though it wasn't too HOT,HOT as far as temps. I don't know what the Barometer readings were.

I personally write conditions on every time slip I get.

I agree with camastomcat. The only thing I'm not sure about is heat range. If that's an NGK plug, in that picture it's a bit hot...maybe 1 range. If it's a champion it's 2 ranges too hot. With blower stuff I don't like blowing the cement off the shell all the way around. 3/4 around is better. But you are on E85 so it may like a bit more heat.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Best pass to date is a 9.3 @ 137 with 6lbs through the exhaust. Any changes to the combo since then? Better track? Better air?
