Yea definaltly smoothes out the onset of a hard hitting turbo! I really enjoy the long runner design over the short but mainly because I try not to rev the hell out of my shit and am not making huge numbers.

I come from a land down under
I played around with runner's as well :)

40mm to I believe 160mm long from memory, had quite an effect on the torque curve and I juggled the 2 to come up with an intake that suited my combination.

It was an interesting exercise but very time consuming and if I had to pay it would have been expensive as well.

In the real world there wasn't enough difference to make custom/tailor made combinations viable.

Well I have had the drawings and designs in the works for a long time and finally spent the money to have the parts machined to build a true fully custom long runner manifold.

Features:
-Manifold is fully custom from the head flange up
-CNC cut head flange
-1.75" mandrel bent runners
-near perfect ports
-near perftectly smooth runners
-NO core!

It is my standard long runner housing design and has basically the same angles and runner lengths as the stock manifold. And for those who are curious the runner volume difference is under .05 cubic inches. The manifold will sit exactly as my normal long runner manifolds do.

So let me know what you guys think!:
Porting:
(also you can see the warp plate I had machined to ensure the head flange would not warp!)

Good work seth.

I see that you have a small 7M plate right next to it, where does that one go:sarcasm:

IJ and Sethron - have either of you attempted to match calculated intake runner harmonics with dyno charts?

Hey Seth how much are these going for and will you sell just the alt bracket . I hate the way the oil line is pinched by the alt.


Matt, I have a bracket you can have...it's one of the older versions that I don't make anymore

it just all wasy to me look cheesy

Well if you were to CNC one it would have to be out of large solid block and cost a lot! I have looked at it and it just isn't worth the extra cost IMO.

Matt I will PM you some information.

Ron thanks for the compliment.....

I had one made and Seth, you are right, that kit was a one time deal only. It was not worth the money. I wonder who has that now?

Hey Seth, does your long runner require the alternator to drop down to where the ac compressor would normally sit?
