Re: thinking about a turbo

ya, unless you somehow do a sh!t ton of custom fab stuff and a lot of money later, it's still not worth it, nor will ever be worth it. the only thing twin turbos really do (someone correct me if I'm wrong) is sort of eliminate turbo lag

Re: thinking about a turbo

Why do you need twin turbos? You could set up a sequential turbo system similar to the Audi Bi-Turbo system (or even the 13B-REW on the late model RX-7s) where the small turbo spools up pretty much from idle, and by the time that one runs out of puff the larger turbo has spooled up.

However this requires a very complicated valving and wastegate arrangement and is very hard to get right. Subaru for example didn't get it right on the Liberty/Legacy B4 from the early part of this decade and the result was a sudden loss of accelleration at around 4-4700RPM. Regardless of how much peak power you've got, if you're having a red hot go on a track (or even just a spirited drive up your favourite windind road) there's nothing worse than shifting into a hole where there's no torque.

For what it's worth, a twin turbo system is too bloody hard for a Prelude. If you're worried about turbo lag, then your better options would be to select a turbo that's more bottom end friendly, or you could use Nitrous Oxide as an anti-lag. I've seen setups like this on WRXs, and the Nitrous is totally de-activated by the time the turbo has spooled up, and the whole package tricks the driver into thinking it's just a larger displacement engine, rather than a turbocharged one.

Re: thinking about a turbo

I actually just took the turbo out of a big rig and stuck it in my engine. running 160 psi at 1k rpm through to 17k rpm. im making about 15000 lbs of torque. it works really well, i recommend it

well there's two different forms of twin turbos; there's the sequential twin turbo found on supras (and maybe rx7's, E will confirm it) where its a tiny turbo that spools mad early and is fed into the second, bigger turbo, which virtually eliminates turbo lag.

then there's also twin turbos on like V8's, where each bank of cylinders has its only turbo.


neither of these options are cost-effective, easy, nor efficient for our cars what-so-ever.

Affirmative.

It's only the 3rd gen RX7 though, for those who don't know. 1993-1995 in the US. 1993-2001 in Japan.

Re: thinking about a turbo

if you want that kind of power get a low profile super charger for low end and grab a turbo as well, the gas miles will suck......but the super charger as i said for low end and the turbo for mid-high.. this set up is only for drag and if you did drag then you would have twin turbos but if your not going to drag then dont get a super charger or twin turbo! stick to your t3/t4 turbos xP

I think he means sequential turbos... that's what most people misconceive as twin turbos....

L M F A O. First I thought 160psi was a typo, then I stopped skimming the thread and actually read it.
