E85 and max power on stock ring gap Well fellas, I have been doing homework to find an answer to this. So far, I have not had a lot of good feedback or luck with my search knowledge on this subject, but it seems my buddy, who owns my old gray coupe will be happy to find out.
We both picked up a LY6 from the junkyard. Both going in to coupes. My old 80 and my new 89. So far he has been onboard ordering everything I order. With the exception of cam. I went with the junkyard dog, and he was asking about the titan king. After talking to Speedtigger he and I both decided it would be fine for the 9.6 compression since we will throw a 4500 converter behind it.
So far I have one guy say he has hit his with a 300 hit. That is a lot of steam from a SBE factory gap. This was with E85. Inusually will limit to 250 on stock ring gap with gasoline.
So, of the boosted guys can make 1000 Hp to the wheels on corn, I am confident we will have plenty of safe tuning window to see where the E85 will take us on the dope.
I will be going to 200-225 on gas for now. I have everything to do it and don't want the car taking any longer to build. He needs everything. So he will need fuel system and carb. His will go corn from the start of things and this will be the fastest he has ever been at the strip with my help. He has a 900 RWHP C5 corvette, but it is useless till the top of 4th gear.
So, I will keep you guys in the loop on this as much as possible.

my sbe 6.0 saw 300 hits and never had a problem as long as timing and fuel was right. FI.
now I'm carbed and switched to E85 and the tuning window is a lot safer. I switched because I use to run a stand alone (FI) and put race gas for the nitrous and 93 in tank. but tune had to be perfect.
example last night I accidentally forgot to retard timing (not wired up yet in MSD box) I ran 36* and 150 when I realized what I did. Also running TR6 plugs, I checked my plugs and looked perfect lol. Now my old setup I would have melted a few plugs and who knows what else. and that would have been at 28* FI as comparison.
E85 is so much better. I went with PRO Systems carb and worked right out of the box, amazing. The shop I use to help me says that's the only carbs to use and work great out of the box as long as your truthful on your spec sheet lol.

Yea, I have never gone past 250 on a stock ring gap with 93 in the tank and a stand alone feeding 110 for nitrous activation.
The E85 should have us going beyond 250 with no problem from what I can figure. Just really hard finding info for E85 and nitrous on the stock ring gaps. One guy confirmed 300.

I don't think 300 will be a problem at all since I hit it a few times on fi and just gas. Just right now reading plugs is a learning curve. Plugs looked brand new still. E85 doesn't color the same as reg fuel. Timing marks are there though. Some have said you don't have to go up a heat range on e85. So a 7 becomes a 6, a 8 becomes a 7 NGK. And timing doesn't have to be pulled as much. After last night I'm starting to believe it. 36* and 150 shot and nothing melted lol.

Pretty sure youll be fine Zones. The E85 can DEF take a lot more timing than pump. My tuner buddy sprayed 300 on a cam only SBE 5.3 well into the mid 9s multiple times with zero issues on pump93/race standalone. Im using E85 in my boosted setup and love it. I would call Kevin at CSU, he is Extremely knowledgeable in E85 and also does a lot of nitrous stuff as well, not just boosted stuff.
