S472 vs danville 72

[hondarider552]

Theres the info we lookin for!

:secret:

 

[jkholder09]

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.

 

[DMAXchris]

My truck makes 50 psi with a billet 75mm comp. 87mm turbine. .90 A/R Stock heads with springs, Hamilton 2.6 cam, 3" piping, stock I/C, 40% inj. Max EGT is 1300º at the traps

Tracking updated again and says out for delivery. Hopefully she comes today...so I can too

I am 99% sure they are the same exducer all the way to a S480.

Sweet! Maybe I will have to snag an 80 cover and wheel just for fun:woott:

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?

 

[JDub]

Are you possibly thinking of the EFR turbos?

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.

What is the maximum boost pressure you guys with the s472's making?
Cams, porting, or stock engine?

from mobile

50 psi on stock engine and fuel

 

[jkholder09]

Are you fella's measuring boost before or after the intercooler?

 

[hondarider552]

After. In my Y bridge.

 

[SSchmi5519]

In the bridge also, 45psi #2 only, 50-55psi on spray. :baby:

Stock heads n shizzz

 

[mike diesel]

No package.

 

[jkholder09]

Mike where in the F&*% is the package.
I have never in my life seen anyone have this much trouble getting a turbo piping kit.

 

[jkholder09]

Have you guys tapped the hot side to look at pressure drop across the ic?

 

[hondarider552]

I barely look at my tach/speedo :roflmao:

 

[mike diesel]

I have mine tapped in on the hot side usually. But the new y bridge has ports in it so I will probably do it there this time.
