1/3 tank. If I plug my time into one of those DA correction calculators it says my corrected time is 11.6@121. idk how much I believe that, but what trap speed would you expect for my car?

Well, first of all you are about 70 lbs lighter with only a 1/3 of tank of gas or about 120 lbs lighter with a drag pack than your curb weight. That alone is worth a tenth and 1 mph . With 462 rear wheel horse and 469 torque and lets say in 600 to 1000 DA I would expect a trap speed in the 122 mph range.

Gotcha, well I'll have to go during a better day then. But also I'm unable to get true E85 like they had on the dyno. Best I've found at gas stations it's typically E60-70. Idk how much that makes a difference but I'm sure some.

That is all I run, pump E85 which is E65 to E70 around here. My dyno tune gave me 440 hp and 445 torque on E70. I am guessing my run weight is at most 150 lbs less than you and I have trapped 123.6mph in about 1500 DA.

I have no headers, all cats and mid pipe in place, a borla touring axle back only , stock air box, and a LT2 intake. You are where I should be with headers and high flow cats. Your ARH system uses its own mid pipe and cat set up right?

This is the system I got:

i would guess all you need is some seat time to run the car to its potential. shifting is everything in an m6 car and is frequently reflected by the trap speed. that car would easily be 2 mph slower on the stock wheels, putting you around 116 mph. which in my opinion is hardly faster than a stock one. mine went 115 when it was completely stock in 2600' da.

i never raced my car at the dragstrip on the factory wheels, but i made some dragy hits just for something to do. 4 things to consider: the car made 441 whp at this time, was 2 mph faster on those drag wheels you are using, i had a 175 lb passenger in the car and the da was a lot closer to 3000'. mid july in central indiana is terrible. the car always picked up 26+ mph on the back half. i frequently saw 27+ on those race stars.

my opinion: your car should be 120+ mph as it sat. hard to say if it's in the tune, driving, or both. et ultimately tbd by 60'.
