VQ37VHR Max HP/Torque

TKomodo · 02-03-2014, 11:00 AM

What seems to be the max HP and torque for the VQ37VHR before internals need to be upgraded? I'm sure there are a few variables but just looking for a guesstimate.

Thanks

Based on you posting this in the FI section...
500WHP/450-500tq

Well... FI just pushed it to 632whp/589tq without built internals. Who knows how reliable that is though.

To be reliable without built internals. 500WHP/450-500tq

I highly doubt the car will be driven on the street at those #s

So you're telling me keeping the car under 500WHP/450WTQ has seen long term reliability? On SC or Turbocharger? Single or Dual? Headwork? Supporting mods?

Look up "phunk"

Torque is the number you need to pay attention to. I'd be hesitant to run higher than 500 lbft.

I would try to keep WTQ to about 400ft-lbs

My tuner doesn't feel comfortable over 400 lbft for a daily driver. A weekend toy would be higher than that, but for a vehicle that I need to get me to work every day without fail, that's where he wanted to stop.

phunk is one of the longest running FI cars on stock internals and he is not easy on his car. he has however limited TQ to around 400, which is the key to long term reliability on stock rods.

Who is your tuner chuck?

I went with Kosmic. They came very highly recommended from the shop that installed my kit.

They are getting mine once the BP kit is installed

What they said, and 500WHP usually translates to a number under 400 for torque. But even things fail at lower power if your not careful with installation work, its probably the number one cause of engine failures here.
