building motor help needed

[dee242]

hooked up my hand controller for the power fc and its knocking on idle now I tried upping the fuel pressure but that didn't help next will be checking base timing and then re map I guess

[dee242]

I got it running right and i got it mapped today but i think my cas shit the bed. I am getting flooding hard to start and misfiring  

[dee242]

So i got the car tuned it made 363 @7450rpm and 18lbs of boost on 94 octane  and 411whp on meth at 24 psi but boost began to fall off after 7700 rpm due to a cracked manifold i believe.  I am currently reving to 8000rpm and will post dyno sheets shortly after i get a new manifold installed and final numbers.

What manifold did you use?

[dee242]

this is the one I cracked 

[dee242]

This is what I ordered for the mean while  I'm going to get this one ceramic coated and see if it holds up if not I will probably get one built

Looks like that will  crack too. That's what the cheap stainless manifolds do. They crack.

Ive got a friend running the same one and it's held up for him so far this is only temporary tho i will either be getting a custom one made or mod this one for twin gates if it doesnt crack
