Haha, unless you have inside information.

Holy shit!!!!!!!! If I hit those numbers, dude, I'll double it to $1000 just for that guess. Wait, can't break my own rules. Those numbers are crazy tho. I can dream. Full disclosure, Matt told me I won't be seeing 800 hp so, I'd revise your guess. If my own tuner says I'm not going to hit the 800 mark, then I trust that I won't. But, then again, we've been low on all our guesses and the numbers have come about a tick higher than expected. I just don't see a 80 hp jump on E85 in 65 degree temps. Humidity is low tho. If we were dynoing in 35 degree weather, we might hit that number, but even still. We are looking at IAT's on our last pull in the 40's. IAT's should be in the 80's this run depending if it's a cold run or hot run. But, I forget the Meth, so that should bring them down to the mid 60's on the IAT's. On a cold run.

You already made awesome numbers for just bolt ons/no opening of the engine. No doubt in part with the radical overdrive you have on your car and the air temps of that pull. Meth is your bandaid for the over drive right now, and E85 will help even more. However, I'm going to bet you're not going to pick up much, you may dyno right at about the same numbers if you figure a 20-30 RWHP pickup but a temp pickup as well. I'm going to say 730/650.

Another note, your car is definitely the first LT4 I've seen with those torque numbers. Usually the LT4 makes just as much TQ as HP or even more TQ than HP. Probably has something to do with timing for those pulleys? Matt is good at what he does, I trust him and it may be easily explainable. I'm just saying it's the first time I've seen a LT4 do that, because usually the numbers are very similar due to the instant high torque of the 1.7L eaton (Advantage to that small size is quick torque).

He's already at 722/643... if he can't pick up more than 8hp/7ftlbs, I'd be questioning the tuner...

Yea, realistically, I think you are more in line. Prob a 20-30 hp/tq gain. Yea, my tq numbers are low. Always have been, even on my base line. I have no idea why but. Whatever. They should be more in line. My Z06 were damn nearly identical. I was 786hp/744 tq.

But, as everyone says. Different dynos. Different days. Different tuners.

Did you forget the temp increase 35 degrees vs 60-70? And the fact that just E85 alone and Meth alone are worth about the same but combining them doesn't double the numbers, they sort of cancel out for the most part, usually a gain of about 20-30 RWHP is the norm with a car already tuned on one or the other and adding the other.

I could be way off, he may make 750+ RWHP and 700+ RWTQ. What I said is just my guess. Tell Matt to summon them bald eagles.

Well, too many variables tho as mentioned before. Air temps alone are gonna kill the numbers honestly. My last pull as mentioned was in cheat air. 35 degrees, running 18lbs of boost. We won't see that today. So, we very well could only get a small bump.

But, I say a good 20-30 should be the range. We shall see. If he pulls a 800 hp pull out his ass, I'm literally going to buy Matt's shop and invest in his business. haha.

No, you are right. I just quoted that below. The air temps alone are going to kill the #'s down a bit from where they were last time. I'm not sure how much cooler the E85 makes it run, but that's on the fuel side, not the air side. My IAT's on Meth should be in the low 60's, high 50's. But, I don't know if it's going to be a cold pull or hot pull.

I'd imagine hot as he's tuning for different %'s of E85. So, I'm sure he's going to be doing a good 4 or 5 hard pulls today. If that's the case, IAT's are going to be prob in the 80's, if not maybe in the 90's. Ah, it's so fun tho. It's amazing the changes in your dyno numbers in slight changes to fuel and air. It's crazy to think it's that delicate.

Hey, all good luck to you man. (Btw, I was referring to a different poster, other than you, in the post you quoted).

Maybe you'll own Matt's shop by tomorrow.
