Mamo ported FAST Vs Mamo ported MSD

I really wish they would. I think there's a market for them. I really want the mid-length runners for my FAST 102. You've seen my dyno graph and have followed my thread regarding the top end loss when I switched to the 1 7/8" headers. I think the mid -length runners would really help out my situation, more so than the normal runners they put in the FAST 102.

Very similar....the gains would just be amplified but the trend would be the same. I think with the insane amount of air you're pushing however the crossover point would happen alot sooner. Lets face it.....you giving up a little TQ for HP is really a good thing anyway!
Hope all is well!

This is quite interesting. I had my hands on probably the first or second cathedral port MSD, but mine is being fed by a F1A on a 416ci motor. I couldn't get the tires to hook up once I hit 700ft/lbs of torque at 4000rpm, so I never got a true torque number. Then once the tires did hook up, I was getting belt slip on the blower since I had the idler pulley in the wrong position, and the spring loaded tensioner had bottomed out.
One thing that I like about the MSD, that I didn't see with the FAST, is the strength and rigidity, and reinforcement for boost. I pressurized mine up to 30psi, and zero leaks.
Tony, do you have any before/after dynos of just the MSD stock vs ported? I'm curious to see the differences.

Very cool write-up. So the MSD is best for big cubes and/or high rpm builds. The FAST is for stock cube and/or torque production builds. And if you are having trouble hooking up, switching from a Fast to the MSD may help. All of this is very good to know. I'm glad there is finally some more options. Thanks for the information.

It would be a better choice than a Super Vic for numerous reasons.....equal length runners (versus staggered in the single plane)....lightweight material that better resists heat (cool to the touch.....lower IAT's is always more power).....and a straighter shot to the intake port....much straighter than a single plane and air (and fluids) never like to turn!
The only reason to run a single plane IMO is you want the classic "look" of a single plane. While I haven't actually tested them back to back, the ported MSD should just make more power everywhere IMO.
Stock this intake is not a good choice.....consider this....it was independently tested during that big 21 manifold shootout Richard Holdener did and it made less power than a stock unported FAST (both of them out of the box versus out of the box).
My test featured in this thread pits my ported MSD against a ported FAST and it beats it up pretty good upstairs.....had I tested it against a stock FAST the gains would have been even greater obviously so the MSD is picking up a big chunk of power from all the porting work I did.
And it's not a surprise on this end.....I take a retarded amount of plastic out of that manifold and increase the cross section of that manifold in a big way....it is without a doubt the most involved and time consuming of any composite intake I have worked on but the results justify the cost and time involved assuming the application makes sense.
Hope this helps guys!

I bought a used MSD from a member here and had it shipped to hio. For one thing the upper shell gasket was effed. But hio sent me a bunch of pics of it and it looks like it's really choked down near the head port. I think this will be a good performing intake up top with some loving in the runners
