How much boost pressure can a built VQ37VHR withstand?

BBRSpeedWorks · 11-03-2014, 07:52 PM

I'm hoping to hit 18-20 on pump and maybe 25 on e85 or race gas

TopgunZ · 11-03-2014, 08:07 PM

I could be wrong but I dont see this turbo going over 21psi.

BBRSpeedWorks · 11-03-2014, 08:08 PM

This turbo did 36 psi on supra it should be able to do 25..

BBRSpeedWorks · 11-03-2014, 08:19 PM

Sasha would be the one to ask as he has done the research with the turbo. I can only go off of what persicion tells me..

TopgunZ · 11-03-2014, 11:08 PM

Mine maxed out around 20.

BBRSpeedWorks · 11-04-2014, 04:10 AM

Well I guess I be building twins for my self then to...lol..

Did I read that right you made 570ish on 20 psi

Nissan370 · 11-04-2014, 05:51 AM

max out at 20psi you should be making over 650 at 20 psi
on a 6266 ???

from what i hear the 6266 turbo does not even wake up til 15+ and should be good til 30 or so

My tuners Mustang read 13-15% low. I've seen some that read as much as 20% low.

Not all mustangs are set up the same. Some read lower than others.

BBRSpeedWorks · 11-04-2014, 07:45 AM

I wonder if he means maxed on pump gas. That would make more since as far as max out the turbo...but idk. I know they read different. But if it's pump I understand but e 85 I don't him should able to push more psi with race gas or e85. My talons on e85..
