Oh yea mine is on 91 octane also. I know yours is 93 octane with meth so thats a lot of timing there. I guess getting 19 degrees is pretty good on 91 octane then.

no, i run 91 octane with meth lol, 91 octane is all i can get where i live, its harder in canada. i used to run 94 where i lived before.

the methanol makes the octane levels over 100 in the chamber when its spraying... but yeah 19 degrees is decent for sure.

Matty are you running your water/meth in the winter? Doesnt the pump freeze?

i unplugged the pump for winter, and no it shouldnt, i run a 80/20 mix, so its almost pure alcohol, it doesnt freeze easily.

where i live i cant open it up this time of year, so the only time i need it spraying is like in fifth gear when i floor it at 60 mph and 2400 rpm i was seeing like 4.5 degrees pull, but i installed 2 step colder plugs as well and it dropped by 2.5 degrees roughly.

and denny you must be using husky/mohawk 94 with ethenol hey?

I make 16-16.4psi of boost.

you must be limiting your boost like you did when you had the revitup stage 1 right?

Nope my car is tuned with hptuners the boost isn't being limited. I think it may be the 3" exhaust. The only reason I say that is because my friend that tuned it he has almost the same mods but has an intake isnstead of exhaust and he sees 17lbs.

yeap that's normal the engine is more efficient at pumping out the waste now with the new exhaust.

yeah the liquid is not going to freeze I was thinking more of the pump freezing up. Weird how I see knock in 5th gear too...

yeap .sunoco ultra 94.

yeah the knock it from the emence pressure, and low rpm/exit pressure , it causes added pressure creating mild knock, the car stock will see it from time to time, especially in canadian climates.

Korax, I have 3 different tunes. On 91 octane I run 15 degrees of timing, on 101 I run 23.5, and on my 101 track tune I run 25.5 degrees.

Only 15 degrees??? Wow that sucks I wonder how much you would dyno @ set up like that. A professional dyno tune would problably help you out a lot for your street tune.

I'm not really worried about my street tune. I spent like an hour setting it up, I just have so I can go WOT without blowing the motor and thats it. My race gas tunes on the other hand have like 15-20 hours of development in them :twothumbs

Blown4-banger, really put a lot of work into his race tunes, and he lays down some undeniable power with them too.

His pump tune like he said is just to drive to work and school.

His race tune, well that's for winning.
