turbo spool

[IanS13]

what are some of the factors that make a turbo spool faster.seems like this turbo spools at like 2000rpm

[:: orion ::]

Technically, it's the exhaust gas expanding that drives the turbine wheel, but...

But higher static compresson ratio helps, as does a little more timing advance, etc...there are a TON of factors.

But the main thing that determines spool is the turbine wheel size and the turbine housing A/R.

What are the specs on yours?

t3 turbine .48 it's a 50 trim turbo.

heat/energy, exhaust volume, manifold design, turbine size, richer a/f ratio, backpressure, . . . I'm sure theres more.

[:: orion ::]

Yeah...a .48 T3 turbine is like a T28 on an SR...takes very little throttle input to make it spool up.

Even a .63 A/R T3 turbine spools by 2500 on a KA!!! (Z31 turbo, specifically)

It's no wonder yours starts to spool at 2000...it's too small.

to small of a turbo what does this mean will it not work right or does that mean less power.

it means you get quickass spool. but will lose power in the high end.

too big of a turbo ..takes a while to spool and great power in high end
