Turbo Size for V8 Engine

[neal1980]

Hi I have a 4.6 Rover V8 and plan to use a single turbo. I have bought a brand new turbo Schwitzer and its bloody massive I think it has a 1.40 exhaust housing. Would this be usable?? Only looking for around 7-8psi. Just done a deal on another for literally peanuts, Brand new still in box.

Looks like they might be from a truck of some kind. Will look good on the mantel piece though if can not be used

Already have megasquirt to control fuel and ignition.

You need to determine how much power you want, then air required etc. Then look at some flow charts for that turbo to see if it's to big.

Without more details on the unit...impossible to say, but 1.4 does sound like a huge turbine housing....although its all relative.

I'd personally go for an HX40 (Holset) with a 16cm turbine housing- brand new for £450 and capable of more power than you're likely to make.

If you want really quick spooling go for the HX35 with a 12cm housing.

Bear in mind though, that these turbos really get into their stride at around 15psi (although they're still pretty good below that).

I use a pair of GT2860RS garretts on an AJP 4.5 V8 but it is a fairly hi revving flatplane V8 (up to about 6500RPM)

[off topic]That's quite a nice collection of cars you've got there, Jon. Have you got a gallery or something so I can have a perv? [/offtopic]
