yeah, .2363 is about 6mm. So 82mm?

BTW, If you are changing your crossover, down pipe and discharge tube why not put a t6 housing turbo on it? Just curious. Food for thought. stuff like that. lol

limitation on the pt88 is the compressor housing, not the t4. i need not go larger. remind me of the post next spring, eh? :rofl:

Which borg is that and what are the specs? Were can I get one? haha sorry for the slight tread jack

Borg warner s480 base t6 flange 1.32 hotside. Billet 82mm compressor upgrade. Flows up to 132lb/min so approx 1400hp.

Retail price is $2400

That one is for sale for $2000

if it were me I would have went t6 as well seeing that the hotside is getting redone.

A properly sized t6 will far out perform a stretched t4. Seeing that a promod 88 is built upon a t6 flange and is rated to 1600hp... seems that might be a little backawards. Wonder what the back pressure ratio would be once you get to 20-25psi with a t4 hotsided 88mm turbo... just food for thought

At the party last night a few of us were trying to talk Dan into a t6 some more. Explaining the back pressure, pressure ratios, turbine wheel leverage, etc. But he is really resisting us. hahaha
