    Thumbs up HPF RHD Dyno Results In - Video and commentary

    We finished dyno tuning the HPF "Right Hand Drive" (RHD) turbo system with some great results. Each turbo system we produce is designed for a specific application. The RHD application was designed for the track / autocross / daily driver and required the use of twin turbos as opposed to one larger turbo as the factory steering shaft and A/C was retained. These GT22 turbos spool so fast that the benefits result from high torque results at very low rpm. The downside is with the smaller turbos, peak horsepower is less than with a comparable larger turbo. On the pump gas map, the twin GT22 turbos slaughter our HPF stage 1 LHD kit with the PT67 as the area under the curve is drastically different. However, with race fuel, the PT67 LHD kit makes significantly more power than the RHD twins as the twin turbos are out of breath at 500rwhp. So all in all, the HPF RHD twin turbo system is great for guys that want to track their car and have immediate power all the time whereas the HPF LHD turbo systems are great for freeway pulls and track events with longer straights.

    Could we get a dyno overlay with a Stage I single turbo?

    Second to last graph, now that is a great power band for the track! Very close to what I'm trying to achieve. I wonder how E85 would impact things.

    Maybe I'm wrong here but the RHD has no meth, right? So I wanted to see no meth vs. no meth or maybe meth wasn't run on the pump gas pulls?

    i find it very interesting that with the single the torque band remains close to the stock s54 band (just higher) yet when going twins the band changes: more torque earlier, (due to faster spooling) but there is a steep torque drop as you approach redline... this is all much more apparent on the racegas comparisons.

    I want to see this graph compared to a N54 RB turbo equiped car. See how much improvement there is from the "superior" M3 engine.
    Are GT22's about the same size as RB enhanced Turbo's?

    If the GT22 are the larger of the two available the compressor wheel is around the same size as the RB. On the turbine side not sure but the RB's have slightly smaller exhaust housings. The graph looks rather similar but would be nice to have a vs rpm graph instead of mph.
    I hope HPF works on a more powerful version of this kit as at the moment it pays me to rather keep my RB equipped 335 than switch over to a car with similar power output.

    Its too bad they do not have an N54 application, I am guessing one is not likely forthcoming if they are still messing around with the S54.

    Well it's sticky who always says the N54 is inferior to its M3 equivalent. But we can clearly see now that the N54 can produce same numbers , even tough the head flows much less than the S54 head.They also always say the N54 makes no top end cause of the head that doesn't flow as much and the small turbo housing. But now we can see that even with a good flowing head and GT22's the power drops off significant after a certain rpm.

    Because of the turbo size, not because of the valvetrain, cams, or headflow limitations. The S54 will always outflow the N54, period.

    singles doesn't take forever and its streetable....you just need alot more room than you do with smaller turbos that max out early. Click here to enlarge
    i like the shift to the left with the TT but no top end is boo boo.
    i'm starting to consider the 6265/6262 more and more everyday.
    theres a balance out there, just have to find it.

    HPF - have you guys considered/postulated what sort of increase in earlier spool a smaller single would net?

    E85 would probably be more than Racegas...

    It will probably also have a 30-40wtq increase in spool.. Thats what we see atleast

    Alot of people forget that increase spool = a ton more tq down low = more traction issues....

    Not if your running an EMS with wheel speed differential traction based control like the ProEFI. It can be managed.
