I must be doing it wrong. Went to track yesterday. Added 5 gallons 98 to about 6 gallons of 91. Went to station and added another 2 gallons to help mix it. Drove 100 miles on freeway to the track.
first run 93 mph 1/8 and 120 1/4 ☹️ Second run 97 mph 1/8 and 122.5 mph 1/4. Third and final run 99.5 1/8 and 127.7 1/4.
eforce with 3.25 pulley.
probably would have been even faster with a few more runs. Dead hooks. Final run chirped 2-3 shift.

Any ideas ?
Race gas itself doesn't make you run faster. What it does do is let you run more ignition timing without engine knock which means you need to have tuned for it.

understood. I need higher than 91 octane to keep car from getting KR. Increase of 8 mph from first to third run really shows how much power I’m losing through out a run without the extra octane.
I have a 3 inch pulley , alky control kit and wideband in my garage waiting to go in.
I think part of the problem here is we have two gas tanks for all we know all of the race gas was in the passenger side tank. Then you went to drivers side when is it got low or vise versa.

. I hadn’t thought of that. I think I’ll mix the gas in my five gallon jug next time. Run the car super low then put that in 🤷♂️
I see you've made threads about it before, but I agree that your quarter mile times are extremely low considering your location. You shouldn't need race gas to trap 128mph. Did you ever get the car to a tuner? And what were your IATs?

I don’t think I have made threads about race gas before but I’m getting old and it’s possible lol.
I was pretty happy with 11.11 @128 personally. I’d be happier with a 10 sec slip of course.
I have a remote tune. I have not installed a wideband yet to allow him to fine tune it. I imagine it’s still a conservative tune. I did go from 11.48@123 mph with canned eforce tune to 11.1 @128 with the new tune so I can’t complain too much.
Once I install my alky control kit , wideband and 3 inch pulley we will be dialing in the tune properly.
not bad times without some parts... the meth helps with the lost octane and it's cheap, so you'll love it. I run E85 (74%e) and only spray in full boost (A&A 3.6 pulley)... so it's not constant. install that kit and see when you are spraying, if it's the whole RPM range, you are definitely octane starved.

you can spray e85 ? I was convinced to go 100% by Julio. Was telling me how you get much not even distribution to each cylinder since the meth instantly vaporizes. E85 would be pretty sweet though.

NO no, sorry.
1. Julio is tight, alky meth is sick and i love my setup. I spray meth... I use VP M1... i used locally produced methanol from the pump (we have a refinery close) and that meth had a 0.1% +- that contained water, whereas M1 doesn't... I saw detonation at high boost high RPM with the **** methanol... also M1 is cheap as all get out, it's dumb not to buy the good stuff.
2. I mean I am flex fuel, so I primarily run e85 so my detonation is already lower, my meth spraying is at a minimum... when I mix with pump gas or run totally pump gas, I spray a lot more meth consistently to compensate for the lacking octane... that's what I meant!

I'm glad you like the 11.1@128, but the reality is that the numbers you're talking about on race gas are what should be expected just from pump gas. To put it in perspective: I had faster trap speeds in a 540whp GTO with a procharger, which weighs a good 700-800lbs more than the C6, on pump gas (121-122mph). You should not have to use race gas to be trapping 128mph with an E-Force C6.
Hence I suggested the tuner ASAP, because you're seeing quite a bit of timing retard (possibly among other things) to be losing 8mph, to the point where you're running numbers closer to a headers-only C6.

I'm guessing your 60' time sucks, since i run 2-3 tenths quicker, a couple mph less, and with just bolt-ons. I'd suggest a 2800 or 3200 stall converter before you get the rest of the mods and your final tune.

for stock stall and gears it’s not terrible was a 1.70. Pretty certain I can get a 1.6 leaving harder. Only three runs so not much practice. Spoke with several stall manufacturers and even they thought a stall would only give me maybe 1/10th because of my PD blower setup. Atleast they were being honest.
will see what happens this coming wed. Will have race gas premixed this time. Last time I added it when I was at half tank. I didn’t realize it would go over to the passenger tank. Car really needs the methanol kit. 3.25 pulley was too small on 91 octane.
wideband kit and tune I should be In Really good shape.

well to be fair my tuner wanted me to install the wideband to tune it properly. Still a safe tune. Canned eforce tune was running 11.4-11.5 @ 122 mph.
headers only c6 run 128 mph ? Wow I guess I should have just removed the blower and leave the headers on. 🙃.
I can agree there is a lot left on the table. Wide band and alky control kit should be going on shortly.
yours is a really high trap. Must be running a lot of boost , nice. Similar setups to mine with more boost and proper tune are in the 134-137 mph range and mid 10s. I’d be happy with that.
Properly adding race gas ?
