IS38 on E30 vs C7 Vette

Dyno'd my car today on pump gas, made 367whp SAE dynojet. After that went to the only place around that sells E85, tested it (was E74) and blended to an E30 mix.

Reflashed the car and jumped on the highway to head home.

Before even the first datalog on the E30 base map, I ended up playing with an automagic C7, had a catback, not sure if anything else.

He had the jump from 70mph. I was waiting in 3rd and hit it when i heard his car downshift. He put about a car on me off the hit and i stopped his pull. Thats where we stayed all the way into 6th gear.

I couldn't reel him in, he couldn't walk away. We let out at 150+mph, not sure exactly but i needed 6th gear so we were rolling. I'm sure the guy was a bit dumbfounded about a VW hatchback having a dogfight with his Vette. I was pumped, it's really rare to have a close race with a random person...and this one was quite a bit different from my last C7 encounter (when stage 2).

We exchanged thumbs up and went our separate ways. Best part was the guy was about 70 years old!

After the pull i glanced at my AP, 27.4psi peak boost and 1-2 degrees of max knock...guess the base map was safe lol.

I haven't datalogged it, but seeing the little knock i had with how much load i put on it, there should be a little more in it!

Yes, it's a pain in the ass but i don't really like the "ethanol content" sensors.

Once it goes to full E85 i know i won't have to test again until the fall. We've been using this pump for years...its dead consistent all summer long, but until they make the switch ill be testing.


Some of your posts are gold :D

I have a test tube also. Haven't used it yet, I have to make the 130 mile round trip to fill up my 55 gallon drum then I'll test and see what we got. I hate not have a single station here with it. I just read an article that the big auto makers met with "the board" about standardizing the octane to a flat 95 which would be amazing

91 oct US, 95 by Europe standards

So they’re just saying 91 oct as the replacement for 87 oct as the lowest pump gas option in US

My old man has my c7. It would still take my GTI for now. I’m ok with that. No existential crisis here. :). But, good to know is38 on corn does the trick. Get on cam??
