Right on.
Anyone looking at borgs new fmw 72mm. They are difficult to come by but supposedly flow 100 lbs/min wuth the 87/81 turbine and 1.25 a/r

Then there is fleeces new 72mm billet.
iirc the new 72 is 105 exducer same as the 76 cast. Now the old 71 and 75 both shared tge 100mm exducer size.

Sorry to hijack but we have a big group of 472 owners here

Is the exducer on my regular 472 the same as the 75mm wheel? I measured it last night @ 101mm. I thought the 75 had a 101mm exducer. If there the same then that makes is mucho easy to convert it.

72 and 75 have the same exducer. 80 is bigger and would require matching the backplate.

Was it the FMW's that people were having trouble with making them live at the pressure ratios we need to run them?

So far no ups guy. Sucks, I have to hit the sack right now or else I will be dead at work tonight. I left a note on my door and told him to leave the package...

Hopefully I atleast hear my door bell and it wakes me up.

Guess we will see here around 7:30 tonight if anything shows up.
