I want to know what's the best manifold between cast iron or stanless steel. Cast iron looks like cheap if you look at the full race manifold. So tell me if I'm doing a good choice if a buy a cast iron manifold.

Cast Iron log manifolds are the cheap/restrictive manifolds, tubular mani's are what you will need to acheive your power goal of 400.

water to air eat exchangers are the most efficent, but 99% of us are using regular intercoolers. Aftercoolers is the cool catch phrase for the SC peeps, technically our intercoolers are really aftercoolers but in the turbo world we all call them intercoolers.

I thought he was calling the full race manifold a cheap cast iron manifold, was about to say wth.

Go with a nice manifold like full race.

Water to air are smaller than big FMIC and less pipings. I will maybe go with watercooler

Sorry for my english writing, I live in Quebec :p

But if it's more good, why not
more expensive and more complicated..

and unless ur running a ton of boost i dont THINK it yields very aggressive gains.

someone correct me if im wrong.

the way SSA does it helps the response and spool alot because it is literally turbo to waterintercooler to intake manifold in a pretty straight fashion.

thats why it has its own mini radiator, to cool it down. water is more efficent at removing heat. you can't even buy an aircooled car anymore(old veedubs and porsches)

lol? water has a lower cooling capacity and efficiency than air? think again buddy.

as far as the question goes, if you want to be able to keep making power all the way to redline you need the tubular mani. you could effectively use a cast iron log if you wanted quick turbo spool but a huge loss of flow up top

When water heats up. sorry I didnt spell it out for you. :wavey:

thats why there is a seperate "radiator" for a heat exchanger, and no its not going to get as hot as the radiator, it will be right at ambient dude.
