but one thing i don't get:
why ams exhaust manifolds? why not msp exhaust manifolds? lots of controversy about ams' copying mike smith's design, using cheap parts, etc.
I'm shooting for mid-high 600's on pump. 2871r cars are putting down 630's on pump gas. As for manifolds, I don't care about controversy. There have been no issues with any AMS manifolds just like no issues with Mike Smith's. Everyone copies a design, that's what makes the capitalistic system and that's what makes competition to produce a better cheaper product. Technically Mike Smith copies stock manifolds. The AMS manifolds are not exactly like MS. There are only so many ways to do (make) one particular thing (log manifold). But like I said, I'm staying out of the debate. I have nothing against either Mike or AMS. When I first bought them I was making half of what I make now and the AMS manifolds were $475 while MS manifolds were over $1000.
this is a review of the ams manifolds by specialty-z:
MS was having the manifolds poured at the same foundry in L.A. that use to do Garrett's exhaust housings.
They closed and MS has been working with a couple other local foundries that are overloaded due to other foundry closing.
Mike of MSP is extremely detailed and has been having trouble getting the quality he demands. He is suppose to have new samples ready this week.
In the past Mike did all the finish machining to the manifolds himself because what he was getting still was not up to his standards.
Something you might find interesting is I saw the AMS manifolds for the first time this week....I was amazed as they are not even machined at all, simply the raw castings. They also had very large obstructions just inside the manifolds head ports on a few of the runners that were just left there and not machined smooth. They did not look anything like a finished product. The ports were not even either.
What I am saying is MS=worth the wait.
i'm not mike smith, so it's nothing personal for me against ams. imitation is the sincerest form of flattery, i guess.
but copying isn't capitalism, it's actually anti-capitalism as there's no incentive to innovate if somebody is just gonna copy you and put out a product that's a lot cheaper.
innovation is capitalism. don't you think there's a reason msp exhaust manifolds cost twice as much? besides the r&d investment.
this is a recent tune by specialty-z, 566rwhp, granted on 91 octane.

isn't the 3076 considerably bigger than the 2871r?
the 2871r, ideally, puts out 800hp to the crank...let's say 20% power loss, that's 640rwhp? i'm not greg & seb over at specialty-z or harry over at ztuner, but it seems like there are these little gremlins that rob you of power.
if the 3076, which ideally puts out 1,000hp to the crank results in 566rwhp (with an unbelievable set-up that most people don't run)...how will you get mid-high-600's?
not questioning you, just doing a small build and looking to learn.
