    550whp 91 no meth. (thats a guess and might be 100hp high/low)
    FBIS's single made 550whp on 93 not 91 no meth
    Were using straight 91 only.

    I expect the twins to hit full boost around the same rpm as a single of similar flow capability. Better would just be icing on the cake.
    i'm going to guess better. i HOPE better. a bit more midrange possibly?

    if it's not better.. well for now it's easier to tune, yes, but if it has similar spool, threshold, boost, flow, power... in future a single will just be SO MUCH easier. probably cheaper too.

    I think the single was 519whp on 91. On pump, hybreds are good for 50whp over stock, singles/V3 worth about 150whp? 525whp on 91 and 550whp on 93?

    This is correct. His car was shipped to us (in CA) with a full tank of 93oct. But his was also the second single N54 we've every tuned. And in the year since then, we have made some improvements in the mapping. We are making the same, if not a little bit more, power now with 91oct. Granted, we've never tried to make a lot of power on pump gas since the idea of pushing big power on low octane gas isn't appealing. We also never expected anyone ponying up for a big single turbo conversion to run on pump gas alone. The 62mm turbo doesn't start singing on the n54 until you go well above 20psi. So running the single at 18-19psi always seemed like a waste of money. And potentially dangerous.

    Regarding midrange torque, this is simply a matter of boost level. In the single turbo mapping, we "limit" boost/torque in the midrange to make the car drive better and to induce less stress on the engine/drivetrain. I'm sure if were to run 22+psi of boost at 4000rpm, we'd see some big torque numbers. But at this level, making power isn't the hard part. It's doing it in a way that you balance risk with reward.

    I really like how linear the singles power curve looks. Huge low end grunt nice, but too much stress on the drive train and less fun when the tq drops to fast up the rpms and "feels" less powerful.

    91 oct with big twins / single will be < 600whp with stock engine. I'd keep the torque < 550 as I'm not a big fan of upgrading the drivetrain parts. Keeping the torque stable is healthy for the car and saves big time in parts, such as half shafts, lock down kit etc. LSD is a must though. Stable torque is good for traction and at the end of the day it is whp that matters, so no need to get crazy with the torque.

    What power and torque levels are you going with?

    Probably the most he can safely achieve.... They way it should be if you're a Beta tester.

    Honestly, if you're gonna spend a couple G's on a turbo kit & "tone it down" to keep the suspension/drivetrain happy, then perhaps you should stay with the Vargas Stage 1s. The drivetrain is "happy" (let alone handling that power that well) when we go FBO with Meth and/or E85, so what makes you think it'll respond better to any turbo upgrade

    It'll make whatever it makes as long as the logs are clean. If the engine likes 520whp/540wtq but the suspension/drive train doesn't... Well that's that's just too bad for the suspension.

    So you would be ok limiting yourself to lower torque figures than what I suggested.

    Vargas stage 1 just doesn't deliver the power we want. I said keeping the torque at around 550 lb ft, so the idea is not to limit the power. 800whp is just fine but 700 lb ft is not. This is for the drivetrain longevity. I don't know what you can break in the suspension.

    No, those are figures that are possible with those turbos. In that scenario the only limiting factor is the snails.If I was installing turbos that could make 800ftlbs then I would tune them to make what they make. If something breaks i would replace it with something stronger.

    Aggressive TQ heavy launches will pummel your Drivetrain (Drive Shafts, LSD /E-Diff, Drive Axles, Gearbox) and Suspension (specifically Rear Springs, Coilovers, Toe Arms) if they're not set up properly.

    94, which was a lie it was 91+100+racefuel, which is not "94"

    Most likely why he said 10-16. We charge a flat rate of $1500 for install. That is 12 hours of shop time for us. But we take our time and always drop the sub frame make sure everything is done right. Trying to rush through these and leave the sub frame in a recipe for poor install IMO.
    Do you have a flat rate for the Stage 3's too?
