Why did you take off the radiator hose?

 

I wanted to get a good shot at the front cover to use rtv, get the crank seal and get the gear puller on. It made everything very easy once they were out of the way.

 

I really don't expect that changing exhaust manifolds would bump horsepower much but I do need to get a handle on egt's. This set up isn't afraid to hit 1600+ degrees in a quarter mile. Reducing drive pressure has to improve something. I just mentioned the four hundred horsepower because of the advertising. I would like to know what set up HTT was using to get those numbers.

 

Iam running a hx40w with water/meth & nitrous only 1300 degrees at end of 1/4 mile without nitrous 1550 degrees @40lbs boost

 

I'm just saying I wouldn't waste 4 bills on an exhaust manifold. Unless you're stock one is cracked or shrunk a lot. Put it towards a turbo that will move some air, with a bigger exhaust side, and that will lower you're egt's.

 

Well, I am all for saving money. I'll do it.

 

I think their setup included a calculator and a bunch of equations. That would determine how much power u can get from the amount of air it can push.
