GTM Performance Engineering: VQ37VHR Engine Build 700HP Power Package

SAM@GTM · 06-01-2012, 03:04 PM

As this platform gets more mature, more and more people go with forced induction. So far, there has been a lot of success and we know that boost becomes very addictive very fast. Usually the natural progression is to build the engine and extract more power out of the car. Arguably, the VQ37VHR engine has proven itself to be a fairly reliable engine and even though we don't require an engine build when customers go FI, it is the natural thing to do when going for big power.

We intend to share this build thread to document what it takes to bring your force fed car to the next level. In this thread, we will be discussing and sharing what is involved in doing so and the supporting mods needed to make 700HP reliably. Stay tuned and enjoy the show.

The Patient

This vehicle we will be using as a case study is a little unique since the engine failed while 100% naturally aspirated with some mild breathing mods. The customer contacted us to do our 700hp package which involves building the engine and installing a twin turbo setup. By using this car as an example it shows that even with simple breathing mods you can still have catastrophic failure.

Equipment on the car at its arrival

Stillen Underdrive Pulley
Stillen Gen3 Intakes
Fast Intention HFC's
Fast Intentions Long Tube Headers
Custom 2.5" cat-back exhaust

GTM 700HP Power Package Components

GTM Stage 2 Twin Turbo Kit
GTM Stage 1 Short Block
GTM Stage 1 Cylinder Heads
Aeromotive 340lph Fuel Pump
Bosch EV14 760cc/min Injectors
GTM Test Pipes
GTM Upgraded MAF Sensors 1000HP
OS Giken Twin Disk Clutch
Heavy Duty Concentric Slave Cylinder for OS Giken
HKS EVC VI Electronic Boost Controller
GTM Custom Dyno Tune

Phase 1: Engine Removal

Since we are doing a twin turbo and an engine build at the same time, it makes good sense to drop the engine. After pulling the motor, we saw that it was completely unsalvageable. It is truly amazing how much damage that a catasrophic engine failure can cause. The block was completely destroyed, the starter was bent in half and the flywheel bolts were completely sheared off. Remember, this was an NA engine with breathing mods only.

Here are some pics of the aftermath.

Was the car tuned? Maybe poor tuning led to its demise?

Any ideas on what happened? That is a lot of damage to happen to an untuned car with just bolt-ons. Seems like there is some info missing.
