The reason it cracked was due to the way it was put together,and nothing to do with it being stainless, that has been resolved on our end, mild steel will hold up just as good, as the stainless. I just hope they are using the right coating or it will come off in very little time.

I had to spin my secondaries around to the Manifold side as well....but I never tried that with the primaries.....maybe I should. Keith was supposed to have sent me some connectors that work since the ones I have don't work.



I am hoping to have it running in a week or so....but I need some sort of a base map to even start my car up with. I think you know my mods. Do you have anything that would at least allow me to drive my car so I can break it in?



I honestly don't know near enough about SS vs. MS so I will not argue with you...I only know what Ivan told me.

Kit looks nice, regardless who makes it!

 

You got that right.

 

Yeah Scott. We can set you up with a "1000 mile" map. After that, the map expires!

 

The squabbling over this "kit" is very amusing. Everyone claiming they "improved" it, but the biggest problem is still there.



BTW, mild steel expands less than stainless steel, and therefore is generally less likely to crack, particularily if by stainless steel you mean plain old 304SS.

 

Before we became RPM's outlet for this kit in the US, they used SS manifolds and DP on all their kits. They had some problems actually cracking the SS manifolds while making numerous dyno pulls during testing, and have since changed to a thicker mild steel setup w/ ceramic coat...we have yet to hear back from anybody who has cracked the MS manifold, and we have sold 7 kits this year and know of 4 that have been installed and dynoed(all of which were MS). It's really up to the consumer if they want SS or MS, but I know I'm going with MS when I have the kit on my FC. I'm not trying to start a war against who's kit is better, and everybody is entitled to their own opinion. Trust who you will, but we'll keep making the kit how we make it, and Aspec can make theirs how they make it....

 

The problem they had we took a pretty good look at and thought of two things, one was the way they were attching the wastgate tube to the manifold so we changed that, the other was due to excessive back pressure at higher boost levels due to flow issues, we resolved that by smoothing out flow through the downpipe and through the dumpipe, we are still making some improvements on that as well. People will start to see the differences when they put a kit I made two weeks ago versus a kit I made yesterday next to each other.



Thanks,Sean

 

Hey A-Spec



What type of SS is that and also what thickness/gauge?

 

The MS shouldn't rust. Most manufacturers coat inside and out. Jet-Hot can do this for anyone. (there is a coating that withsatnds 2000 degrees, but is a dull grey)
