Sean you have to understand that you (and I) are BARELY in a GT30's real efficiency range. The 24/18 is on the end of it on high boost. Lets say you turn your turbos up to 1.7 or 1.8 bar the difference will REALLY shine. The 24/18 will not make the power like that on that amount of boost.

Yes Chris, there is 105 hp difference between 1.2 bars and 1.5 w/ my GT 30's. I know that 1.6 would give me 35 more hp but I am afraid my stock bottom end would not like that.
However I am still unconvinced that the 28's will produce more power than the 24/18's.

i'll dig up some of the 28 dynos
this one is actually a smaller gt28 variant, the turbine wheel is much smaller than a standard 53.8mm gt28 turbine wheel, and also has a smaller compressor wheel (this was on an Audi S4....i'm still digging for the 996 dyno's)

Ditto Doc and as far as I'm concerned I am rather attached to my engine staying in one piece. So I'm not interested in pushing 1.4 or more bar.

i've been told they work very well, only thing you need to change out are turbos (obviously you need the supporting mods)

what are the highest #'s you've seen from a K24/18g car?

Boost doesn't directly = cylinder pressure.
Boost doesn't directly = detonation.
Boost doesn't directly = engine failure.
Running 1.4 bar of boost daily, on pump gas and for a very long time....is very possible.

I have never heard of any 28 ever making anywhere close to that kind of power even on full out kill mode. I don't buy it.

Yeah I think Chris is at 701 or something like that. He's running a E85 setup on his 18g.
