How much boost pressure can a built VQ37VHR withstand?

My Built 4.5L has already seen 30+ PSI... Then again my motor costs more than a new Z...

The Stock intake manifold is going to start to be questionable around 800rwhp... Also boost is going to be relative to each build the turbos on the build and supporting mods.

However, if you are comparing block to block I know the regular built GTM Motors and ones built by Speed 4 Sale have handled deep into the 20+ psi range.

If you go with one of the more built motors like mine then you will need to be looking at other supporting mods to truly take full advantage of their capabilities. for example I run a GTR intake Manifold, I have built Heads and etc...

yea you have to know what you want out of your car
track car
drag car
drift car
street car

For me its all about the street car life and 600-700rwhp will have me killing most cars i come across on the street

i do the drag strip maybe 3times a year and this car is my summer car so that hp level will work great for me.

small example last weekend i pulled on a 2013 gtr in 4th gear having him only jump pass me as i shifted into 5th gear (paddle shift wtw)

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..

BBRSpeedWorks · 11-04-2014, 05:04 AM

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

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