I bet a Mamo ported LSXrt would outperform the MSD intake. I wish you could get one of them to fit a 4th gen without having to cut it up.

The title did not specify the 102 but thank you.

Awesome thread Tony! You told me about this the other day but it went past me. I thought you were talking of something else lol.

That's is definitely impressive from the msd intake. Great work as always tony.

It will be interesting to see how the mid and short runners compare if and when FAST finally releases them.

They're not doing it for cathedral heads.

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.

Looks like we need to start calling them. They get 3-4 request a week hopefully they will take notice

Great read, thanks for the info Tony. Still hoping Vararam throws their hat in the ring one of these days..

Thanks for the write up Tony! A llsr would work well with that Mamo MSD!

Hmm.....wonder how the MSD would preform vs the FAST when you add forced induction.

Tony @ Mamo Motorsports

I agree....a short travel hyd build or an LLSR is certainly the way to go with the MSD to get the most benefit from the swap

What took you so long....LOL

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.

Not to highjack the thread but what about a Super Vic?

I have an LS6, Darton Sleeved 447 with a 4.125 crank, big heads, big cam, etc, etc....
Would the Super Vic be the best choice for this application?

Great write up Tony!

Kind of depends on how high you plan to spin it. What are the specs of the cam? I know most cam guys will spec a cam differently based on if you're running a composite intake like a MSD, FAST, LS6, etc. versus a single plane intake.

DavidBoren

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.

Tony @ Mamo Motorsports

Honestly the ported MSD is the manifold of choice if you're willing to spin the engine (and have the valve control to do so) in an effort to go horsepower hunting.

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!

So what gains would you expect from a stock to ported MSD for those of us who already have a cathedral msd on our cars?

big hammer

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
