Billet Engine Block

He will have a way better engine management program the. 99% of any VHR owners. He has been through the entire motor, his heads will hold. It’s a similar process of how soho did the heads.

That doesn't matter. GTR's go billet aluminum rods above 1200-1300whp.

We going to find out. I said the same thing. Why not just go billet crank and aluminum rods at that point. Who knows it may last for a couple runs. My buddy ran 1700whp and didn’t use aluminum rods in his GTR. Never blew a motor.

He better have deep pockets. He is going to break a ton of parts.

Elmo370z

What we spent on our entire build, he has that in the motor lol.

Spooler

Ah, not mine. He is going to need a couple of them. He just doesn't know it yet.

Elmo370z

Trust me.

I wouldn't use aluminum rods in a street motor. Only in a drag motor. They have a limited service life because of definite metal fatigue life. In a drag motor. You normal tear it down at least once during the season to inspect everything inside. That includes measuring rod stretch. With using aluminum rods. You have to watch your deck height. Normally you set your piston below the deck because of stretch. For the street. I would be using Carrillo rods. Have used them before in my 572ci big block Mopar.

That's why nobody uses aluminum rods on the street. They have a limited life and require maintenance and replacement. Why do folks over 1200-1300whp use them on a GTR? To prolong the life of the crank and rod bearings. The V6 design is hard on cranks. Why the guy above didn't get a Bryant crank is beyond me. They will break above 1200whp. When you get above 200hp per cylinder is the problem area. RealStreet did a video on it.
