Engine/Transmission (1994 - 1998) turbo CFM

[jkh]

I just found out a stock turbo flows 500 CFM and a PDR35 flows 620 CFM.

Anybody know what a HTT 62/12 or an II 62/12 flows?

When is the flow measured?Is it at wide open throttle,or is that max under perfect conditions?will different exhaust housings make a difference?

trying to learn what I can from you guys before I buy.

thanks.

will different exhaust housings make a difference?

Yes, they will. In both flow, and spoolup. Same goes for the compressor wheel you get.



Since you have 3. 54 gears, I'd probably go with the 12 housing. If you had 4. 10s, I'd probably go with a 14 housing, so it won't be as restrictive in the upper RPMs. Both the II and HTT turbos have dual wastegates, which really helps on top when they are open.



I have 4. 10s, and can spool my 64/14 pretty good, but there are times I wished I had the 12. Their new SS 13 housing might be a nice middle ground. As well as a great looker under the hood.
