gt35r

[p5150]

so if someone were to want 500+whp on pump gas (91), and upwards of 600 on C16, the GT4067R would be the best bet in terms of lag time in comparison to power goals, or am I still slightly unedjumacated?

I dont want to sound like a know it all, but I think you might have the nomenclature of the GT40 a bit mixed.

In your nomenclature, you refer to it as the GT4067. Everywhere else that I have seen refers to the GT40 as either an 82 or 88 mm wheel. IE: GT4082 or GT4088. Are you referencing a different part of the impeller? Are you using the "67" to refer to the AR of the turbine housing?

It goes gt40>gt3540R>gt40R>gt4067>gt42

As gay as quoting your self is

4067 is a hybrid with a 67mm inducer instead of the usual 40's 63mm one.

OK I see. You are measuring the front of the impeller instead of the aft portion. Im willing to bet that the back of the 67 measures 88mm. Otherwise known as the GT4088

4088 inducer is 64mm

Been trying to pin down some exact info on this but it's like the 3040 nightmare all over again!

4082 = 58mm inducer
3540R = 61mm inducer
4088 = 64mm inducer
40R = 65mm inducer
4067R = 67mm inducer

Add to this a lot of Exducer sizes and you get many different combinations as I mentioned the 4067R in theory is a great match for the 7M if it's let rev.

I havent seen any 40r turbos. Every web vendor that sells "temporarially out of stock"

Yep they're a bit rare but so was the 4067R before it became popular!

I'm waiting for KwNate to sort a few bugs then get back to me with some spool data on his 4067.
