How much boost pressure can a built VQ37VHR withstand?

KratikosG37 · 11-06-2014, 10:16 AM

What happen to the build and what's the dyno chart like?

Here you go. Those DE engines were only good for about 425whp before they let go. So instead of building that engine and putting on a smaller pulley and turning up the boost...I just sold both kits, the car, and bought the VHR.

BUT...Were we just speaking of 400tq at 4K. I had 411 by 3250...Lol..

Idk y everybody think singles spool slow....I'm just wondering if I'm going to be laggy after my built motor goes in...

What are you dropping the compression down to?

I don't think that. It all depends on kit, tune, and engine set up.

Most single turbos don't spool as fast as twins. That's my point when you said, "I don't spin".

TopgunZ · 11-06-2014, 11:11 AM

A properly sized turbo (like the 6266) will not be laggy. Singles get a bad rep as being that way because guys in Evo's and STI's are running giant turbos and are going for 800whp out of a 4 cyclinder engine. Those things are laggy as hell.

The fact that we have 3.7 liters of displacement makes us singles comparable to twins. Twins will still spool the fastest though. Now if they weren't just so damn hard to install.......

i'll be 100% specific in future posts to avoid any confusion.

It's ok.

IMO VQ is VQ but I see the major different between DE/VHR

Yes, but DE we're TQ monsters if built.

Yes yes you made you're point.
