Are you stock now? If so this difference will be astounding! You got to be stoked.

With your comprehensive list of mods, you should be around 660-700 whp with that E85 (or blend) / meth combo. Dyno won’t mean a whole lot without a baseline done during similar DA conditions, I recommend spending $170 or whatever a Dragy costs now to get some meaningful measurements.

I’m only stage 2 OTS E85, full bolt on S8 without meth/cooling and doing 0-60 in 2.77 on the street with normal tire PSI, so your mods you’ll likely eclipse that, although IDK how the compression ratio differences between A8 and S8 engine will impact results. Enjoy!

Yes stock with a V3 sprint-booster throttle controller always on Race #9.

Just order a draggy $ 179.00

Compression ratio A8L 10.1 : 1
S8 9.3 : 1
