Well sort of a carry over from the other poll If I can get these made in steam pipe and track prove that they dont crack would there be interest in an external gate compliant Zed Racing Evolution manifold. Prelim costs would be between 1.5 and 2k made locally or talking to overseas suppliers for manufacture then import them directly. What do you think
Like I said in the other post, waste of time and money. You cant guarantee they arent going to crack with steam pipe. Who would pay $1500 to $2k when you can get proven cast iron manifolds documented to flow almost better than anything on the market for $1500? Better to just group buy the MS is my opinion.
If they flowed as well as the Pentroof ones do, didn't crack and were made with the choice of internal/external gate and different flanges i'd buy a set.
Hmm, seams a little too much for something you really can't see, and being there is a risk of cracking I would have to say no. The cast MS manifolds are so much like stock ones which never seam to have a problem I'd be more than willing to shell out for them instead and never have to worry about cracked manifolds agai.... hang on, I don't now. I'd only start if I put on welded ones
would the manifolds really make that much difference when you have the huge restriction of the turbo directly on their outlet? has anyone looked at running 2 exhaust cylinder outlets into the turbo and bypassing the turbo with the 3rd outlet or would that take too much pressure away from the exhaust turbine?, i think it might be an interesting experiment,
Stay away from the back of the shed dude, hanging out there is starting to mess with your head But if I have to bite, then think of what the turbo sees.... Pulse, pulse, nothing(slows down) pulse pulse nothing. Great for reducing boost by slowing down a turbo.
Yes it does. Basically almost everything done to improve engine performance is to increase flow through the engine. Intakes, larger valves, cams and cam timing, porting and port matching etc etc. Manifolds are one of the biggest restrictions. Sure you can make good power with some big turbos and using stock or extrude honed manifolds but your missing out on a lot by bottle necking your flow at this point. Yes it all stops when it hits the turbos, but the more flow and velocity that hits that turbo the faster it spins.
To be honest, no. I don't think there is a market that exists between the price of the MSP manifolds and the price of the Pentroofs. MSP manifolds will flow enough for all but the most pedantic of power freaks, and to those power freaks, they are going to want the best and will pay for it (Pentroof). Just IMHO.
