Thread: If you could make your own intake manifold

any thing made by hypertune is designed very well

perfect injector placement
u want your injectors placed as close to the cylinder head ports as u can get it
u want the injectors to be spray fuel directly into the intake port so its aiming at the back of the intake valve ( u wont want the injectors to be spraying into the runner walls )
u want the inlet of the plenum camber ( throttle body ) to flow air into the tops of trumpets NOT THE SIDE OF THEM

i remember seeing a picture posted on here where the member had a custom inlet manifold made and he had the trumpets sticking up so far into the plenum camber that the inlet was flowing air into the sides of the trumpets
very very bad design

That design is the only way to achieve proper length to make power for an NA application.
That design made 6whp over a flush stack manifold that was 2-1/2 inches shorter.
Making close to 14whp over stock on a stock VE is huge in my book.

With the space in the FWD chassis there is nothing else you can do for a plenum based manifold. Not to mention not even having enough room for a large enough TB.

Having small engine bays suck. Its really one of the biggest downfalls of our chassis.

i would much rather lose length in runner and gain better flow into the tops of the trumpets

in a rear wheel drive setup its the same

this is the clearance issues i had

And make dog shit for power.

Been there and proved this already.

Jamie has tried both, the longer runner made more power. Same trumpets from what he said, one being flush on the bottom of the plenum 2 1/2" shorter runner lengths and the other 2 1/2" longer sticking into upper part of the plenum. In an N/A application, not turbo, it made more power with the longer runner.

N/A and turbo runners and designs are by far two different ball games. Smoother flow into the stacks is better for turbo by far than protruding stacks. N/A, getting proper runner length is more important. Perfect would be proper runner lengths with a good flow into the stacks. But its very hard to do on our fwd chassis.

update: Yes there's endcaps on it...no copying.

Going to try and center mount your TB?
