Ah, I misunderstood your direction then.

A pretty good question, I'm not very tollerant of stepping on the skinny pedal and watching the boost build. What I'd consider "lag" would depend on the application though to be fair.

In the case of a track car, I don't even want it to be detectable really. Something so responsive you hardly know if it's turbo or not is a great setup IMO. When I stomp on my throttle above 5k there's just a fraction of a second between nothing and full boost and that's of course the way we'd all prefer it. Essentially if I roll the throttle on mid corner I don't want to have to slowly back off the throttle continuously through the corner because the turbo continues to spool harder. If it does function that way it's taking away from my driving focus that'd be better spent elsewhere.

In a drag queen I understand a full second plus anywhere in the range to get to full boost, though you know as well as I do what it's like to drive a car like this around on the street or on the track.

Exactly my thoughts.


It hardly even feels turbo at that point and that's what I'd shoot for.

05TurboS2k

Well.... I mean sure but that's true of most any setup. If I stomp it at 3k it doesn't reach full boost in a fraction of a second....though that'd be great.

Yeah I'd really love that. Whats the max the gt28rs turbos can put out for our cars? Or similar sized turbo? Could those still achieve 400+whp? I would imagine they would hit full boost VERY early in the rpm range.

05TurboS2k

I looked into a 28rs for our cars. I HEARD or numbers around high 300's but the highest I ever personally saw with a dynosheet to prove for 350whp, that was a few years ago though.

I figure it'd be amazing on track, even at 350whp it'd be a highly effective 350whp and tons of torque nice and early in the rpm band meaning gear selection wouldn't be very picky, you could probably roll the throttle on at 3000rpm and casually pull away from a stock s2000.

Ahh, had to read it a second time to see what you were saying.

I'm on a SC34-BB right now which is good for around 550bhp. I built my motor for 800 and always planned on around 650-700 range at least in the near future so I was considering perhaps a GT35R or something similar.

HOWEVER, I'm now seriously considering a GTX3076 in large trim (.82) perhaps and shooting for 600whp not being upset if I show up a little short. The tough part with this is my stock turbo is good for about that so it is perhaps a little silly to trade it for another that does the same thing nearly but the spool would surely be sooner and the top end possibly a little higher even. I'm curious to see what the real limit of the GTX3076 with a great manifold could achieve before it starts choking up so bad I start with heat problems. I would imagine it'd make incredible torque numbers, be a blessing on the street for daily and a monster on the track. Perhaps I could sell my turbo for some decent $$ and make the upgrade, mines water cooled and around $1250 new, I wonder if I'd be dreaming to ask for 900 for it if I rebuilt it for the next owner.

Yeah that would be perfect IMO. Would have almost instant boost like the Greddy kit but actually make nice power to redline!

^ Exactly what I was telling a buddy who had the greddy kit but removed it because he was unhappy with the results such as limited power/ boost creep/ etc. I told him go 28RS and he'd be in love with his car again.
