    No i'm on a p1sc...kicking myself I didn't spend the extra $200 for a p1x when I placed the order. :(

    You put the p1 back on or go with a smaller pulley on the d1?

    Folks have been 9.40s on a p1sc in a s550. Your goal faster than that? Not sure why one would want a big blower and turn it down when a smaller blower at full tilt yields the same result.

    Why not turn up the D1? Put a 4.0 on it and take the wastegate off. Way cheaper than swapping to TT.

    The D1 stops making steam just over 900whp. To even consider playing at TX2K I need to be above 1k. Twins come into play when I build a short block. D1SC just won’t get me there.

    I’m not running the Wastgate right now. Making plenty of steam on just the 4.63 And E85. Once my converter gets here I’ll be able to make some passes to get where it’s really at; built trans is sitting waiting for it.

    There is this pesky guy in Dallas @Black Dog that keeps giving me crap about how his TT setup will rape my D1... pretty sure he is right...

    No def not looking to be at like a 9.50, I don’t have a set goal in mind. I just want the car to feel good in the mid range, like hitting the pedal at 3k roughly. Doing that in third gear right now doesn’t feel all that amazing. This also is a street car 99.9% of the time so I’m not spending a lot of time past 5k.

    With a 4.75 on pump you are probably making 570whp, so yea not that amazing in a heavy car. My car went 9.80 at 141 on pump with a 4.0 fyi

    yeah that's hauling the mail, for sure. anything over 130 in the 1/4 and i think i'd be happy. the car just feels a tad lazy in the mid range, hopefully a 4.25 will liven that up. worst case scenario i pulley down to a 3.85 and do a torque booster next year.

    All mods are in my sig. Can't see it from mobile device tho. Basically circle d converter, full exhaust and 2018 intake. It's all about optimization. Most folks never get the most out of their combo. I eek out all it's got. Fore fuel system, e85 and 3.7 pulley track times soon. I'm looking to be the quickest with a p1sc. No wastegate, letting it eat.

    yeah the auto def helping you get that awesome e/t and the exhaust and 18 intake like you said helping you extract the most power out of your setup. any reason you didn't go p1x when you picked up your kit? for $200 i regret not doing that upgrade.

    I bought this car with the p1sc already on it. U won't max out the p1sc, why have regrets not buying a bigger unit?

    I thought the p1x powerband came on stronger and pulled harder...maybe I'm wrong, in which case I have no regrets.

    P1x is gross. “Midrange” on command, but my converter flashes instant to at least 41-4200. The whole 3,000 midrange is just silly. Coyotes want to breathe at 7500+. I start seeing positive boost about that 4000 mark if I force it to lock the converter lower than that on like a 3rd gear data log pull.
