    It's due to the fact that we only run up to 23psi, which doesn't seem to be enough to take advantage of the new billet wheels. I'll bet you'll see some good numbers at 30+psi

    I dont' think so, I think it'd just prove that you 60'd and drove the car better. I've seen some MKIV's that have gone 9's on a 67 and as slow as 11's.

    Same car.. same driver. Only difference will be a new turbo, ProEFI, E85 and some Tial BOV's instead of the HKS's. So if I go out and pop a 10 second pass on my first try.. I would say that would be more to do with my planning and the changes made.. than my driving skill.Click here to enlarge

    I have a Sony HDR AX2000 and 2 GoPro's so you can be sure it will be caught in full 1080/60i HD goodness. hehe..
    I think the problem is the chassis and transmission more than the turbo.

    Of course it is, I was preaching that a long time ago. Some people even called me dumb.. so all the more important to have a power band that works better with the chassis and transmission. Since it's not feasible to change the chassis and gearing, the obvious change should then be the power band. I came to the conclusion people were going about it ass backwards. Trying to make X work with Y and Z.. Why? Isn't it easier to simply change X?

    Give it some thought...

    The reason we're all hitting low 11's regardless of 600rwhp or 900rwhp is the 60ft.. noones put proper wheels/tires on the car yet, and noones tuned the suspension/etc for the strip. My car was having all sorts of issues, idling, boost leaks, etc and on some ancient drag radials on the first (and only) pass we did 11.3x @ 135.. in 100 degree heat with a high DA and that was with the foot off the gas for the last 1/2 a second being we werent' actually trying to run the car.. we were dialing in traction control/etc. We got the boot regardless and didn't get to try again. The same run on a 75 degree day with the pedal through the finish would have netted a high 10..

    If you go run your car with the exact suspension/tire setup as you did at MFest with this smaller turbo and left orientated power band I'm willing to bet you'll net a higher time..

    The topic has been beaten to death but its not the engine, its not the powerband, supras had the same issue (and still do, with the exception of those who took it seriously).. its the traction, the launch and the driver.

    Its also partially the components as our driveline is just weaksauce. :\


    Edit: I also believe the gearing plays a part.. but i'm not overly confident as the guy from sweeden lowered his gears to something like 2.97 from the stock 3.73? (or is it 3.62) and had massive slicks on it and ran a high 10. If he'd had run it with the oem gears then swaped and ran it again that would have been awesome data to know.

    I really didn't notice a traction issue much at MFest. My car simply felt weak leaving the line and the power didn't seem to come on until midway through the RPM range. Then it would sling shot. It just didn't impress me leaving the line. For awhile I was thinking it was the lag, or spool time. But the more I thought about it, I started looking more closely at the actual power band itself.

    The fastest ET here in the U.S. is still held by Rob at 11:00. Take a good look at his power band... You see that large, broad power at the top? With our gearing, we need a broad power band.. not a narrow one. I'm pretty confident the power band is a contributing role.

    I just think the E46 is a $#@! to drag race in general.

    For the amount of money you've spent on this all I would have kept the HPF setup. If the power band wasn't to your liking I would have gone with a Tractive RD906 and gearing that matches the power band. You keep saying "you need a 3k rpm power band" but what you're forgetting is that gearing can be changed.

    I would much rather have a Holinger than a Tractive. I will most likely go to a 4:10 R&P too. I can sell the Pt71, so it's not like I'm spending that much more money.

    Well I'd much rather have an F22 Raptor than a Cesna but since I don't have either....

    Point is - if you're building a dedicated race car and you talk about specific power goals, then make the power and put the gears in that range. Why do you think new cars have 7 and 8 speed transmissions? Hint: Its not because it's "cool".

    It's a lot easier to just play with setups and say "Ah well I liked this setup but... it just wasn't ideal... and this other setup... yeah it was good but I didn't like that either..."

    Are you building a race car or not? Gearing it is easy.

    Q: Is the E30 chasis (djborya's) better than a E46 M3 chasis? I dont think so.
    E46 M3 chasis is better.

    Supra and M3 trasmissions are similar, not identical, so we should not focus on the trans.

    Tire/wheel combination
    Wheel alignment
    Power band
    Amount of max power
    Max engine speed
    Anti lag
    Driver skills

    Someone out there will play around these variables and come up with 8 s runs.

    Noone has played "enough" with these variables yet.
    E36 M3 Euro TT 60-130 mph 4.49 s
    E46 M3 3.6L TT 60-130 mph 4.22 s
    All Wheel drive M3 Twin Turbo
    997 TT

    def E30 has better chassis for DRAG RACING.

    Look at you posting again. This is quite the system, eh? Unpredictable.

    Not yet, but I'm working towards that end. Eventually I will put the entire drive train into a gutted race prepped car. I'm also going back to DIY.. no more shops for me after ProEFI.

    I think plans change based on what he is doing. Nothing wrong with brainstorming various approaches.
