Message I received a customers parts today and proceeded to inspect them and noticed that there is a small issue with the clearance between the new cast manifolds he purchased and the new SZ turbo kit he received.

Has anyone had any problems like this? From what I gathered I'll need to grind some clearance between the manifold and turbo however before I do that I will try and rotate the comp. housing a little more to see if that clears the manifold. In any regard I believe that the manifold is too close to the comp housing and will soak up radiant heat from the manifold making the intake temps excessive. I can add a heat barrier between the turbo and manifold but again Im not sure how much clearance will come up after I try to clock the turbo more or grind clearance off both the manifold and the turbo.


I did do some investigating on the manifolds (AMS) and noticed that between runners there's an average of .050" difference between each port from left to right. I know core shift is something that is extremely hard to fix and keep tamed however inconsistencies do become a problem with flow as well as out come of a finalized part. One other thing is that from looking at the AMS manifold they do not debur or roll edge any of the flanges on the manifold which is important in a production part. Cuts down on customer injury due to minor cuts/scrapes and it also helps the overall appearance of the part.


I don't remember the measurements that I saw a few months ago that Vuk had posted about his differences between the MSP and his manifolds but I did measurements of my own and as I stated above they were a little inconsistent.

Needless to say...quality overall is good..just some things I hope both SZ and AMS pick up on...since the AMS manifold is cheaper many of the community is leaning towards purchasing those than the MSP part...to each their own though. I've seen both and think both offer just as good performance as the other. I figured that maybe SZ and AMS may want to collaborate or maybe look a little closer into this.

Just my findings..that's all.


On a side note...Here is what came off the dyno in the back. Gotta love Pro Mod Drag Boats 2100HP bullet on the water. Hoping to have a VG motor up on the dyno soon enough!
