Now you can put up comparisons :)

T3 .63/.60 CFM?
T3/TO4E .63/ 60 trim CFM?
Hi-Boost IHI Turbo CFM?

Etc... ;)

It isn't a map for "our" particular turbo, just a range of T series turbos. There has been no posting of an application specific compressor map to date.

Yeah and 140kw is about 190HP......so this isn't our map.

10-12-2003, 06:14 PM
Not to mention 190 hp is assuming alot about th eengine being fed.

the .ar size and all that.
Do you know how many people ask me about it. Now i know what to tell them!! :)
1sty
10-12-2003, 09:04 PM
And what exactly does that tell you thats useful?
KyRaceFan
10-12-2003, 09:17 PM
useful? i guess nothing.. but it is nice to know how big and how much the turbo can flow.
I just said thanks for the info, not thanks for the useful info.
Is knowing your paint color useful? No.. but its nice to tell people you have a black mica car, and not just a black car..

Paint color is useful if you need to know what color to paint something.

How much a turbo can flow is only useful if you know other info too, like how much you need to flow for a certain engine to achieve a certain power. Also how much of that flow is considered effecient.

So, does anyone know the inlet and outlet sizes ? I rally dont feel like ripping off my intake hose, and charge pipe hose, to find out. :D

I'll measure it if I take my Injen off this weekend. I believe its around 1.5 to 1.75" inlet ID.
