    high boost pump gas + low % meth datalog...

    ... I'm addicted to meth. I finally had time to finish up the install and do some testing tonight and god is it awesome.

    Right now I'm running a low % meth mixture because I had a bunch of water left over in the tank from when I was testing/priming it. I poured in some 50/50 mix so I'm probably around 40% meth / 60% water. I'd like to eventually run 70/30 especially after seeing how nice the logs look

    this datalog was the LAST datalog after doing a bunch of pulls for about 10-15 minutes on the highway... it just goes to show how consistent meth/water keeps things.


    Pump 93 + 40%meth/60%water.... peak boost of around 20.5psi. 3rd - 4th gear.

    you like 20 psi huh Click here to enlarge

    IAT's start to climb again when doing longer pulls, what size nozzle? Timing looks like it can get better in 4th as well, im sure 70/30 mix will bring that up though.

    Sure is fun thoug eh Click here to enlarge

    Yeah timing will improve with the higher % meth mixture, i'm definitely impressed with the logs on pump as and this lower % mixture though. I can't wait to run 70/30!

    I think the best thing of all is the consistency, this was after a tonnnn of pulls. Meth rules


    M7 nozzle if I remember correctly?

    it feels GREAT, definitely a nice combination. The best part of all is how consistent it is even running 20psi

    nice....i guess for the 3 of us we need the new MAF sensors and fueling and we will be able to boost ALOT more than that huh?

    It's all very uncharted territory at this point, i'll be sticking around 20psi on pump+meth.... i'll see how the logs look once i get a better meth mixture going on.

    i said that at one point too Click here to enlarge

    if upping your % doesnt help, stay w/70-30 and jump to an m10 and try that. If that doesnt work, which im sure it will, then go back to m7 and try 80/20, and repeat.

    The convertible 335i is 400lbs+ heavier than the 335i... that is a huge difference. You're going to need more than the same exact mods he has to stay with him.

    im guessing im gonna be about 3-4 mph faster, at same power/mod-wise, wich will be about 3-4 cars, depending on how far we go.

    maybe some lightweight wheels? CF seats, if you find some to fit in..

    - oh damn.. more OT



    JP. after looking at your iat's again, you may have a flow issue.. it rise just a bit too fast in 3rd, and then way to fast in 4th

    **edit** never mind, its in C* yes, thats ok,BUT you should be seeing lower, much lower than ambient temps.. which again, may be a flow issue
