Billet Engine Block

I think you can still give up a nut......

It’s letting students cut your big toe off and re-attaching it. Well two people are going to test how strong the VHR blocks are. One is soho using aluminum rod set and the other is in my opinion a proper drag set using steel rods both aiming fro around 14-1700 whp.

Steel rods over 1200whp are a recipe for a broken crank if the dang headgaskets will hold.

Elmo370z

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.

Spooler

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

Spooler

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.

Elmo370z

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.

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.

Mr.Squeeze

There are plenty of GTR's making over 1300whp with steal Rods. Manley makes a Tri beam 300m Rods that are used In GTR'S well above that.

I am sure some folks do just like anything else. There was a video posted in my thread from one of the guys at T1. For a reliable build, one that the motor doesn't need to come out but every 2-3 years to be refreshed, they use steal rods. Anything above that and they recommend aluminum rods. Those have a limited life span and require much more service to be done on the engine regularly.

Unfortunately, we don't have the development money being spent on our platform like the GTR guys have. We only have SOHO and a couple of people pushing the platform along as best as we can.
