I’ll have an interesting side by side look soon to compare a mamo ported MSD vs a mamo ported MSD short runner version by one of the CF members on here. Should be fun to see that is ONCE I get all my other issues ironed out....

MSD runner I believe is around 9.5, probably going to move somewhere between 7.75 - 8.25. Would like motor to peak around 7100-7200, rev to 7500 - 7600.

Not my favorite look, but I don't find it overly offensive either. Definitely its 1 of those looks though that you better be able to back it up because it screams "I'm fast" haha

Sic,

What's up! Exactly, on my own combination with one of my modified Short Runner MSDs, one of my Cams ("The War Stick") and GG ported castings: 665RW @ 73xx RPM, still making 659RWHP at 7750RPMs with over 600RWHP as early as 55xx RPMs. All with 21* deg of timing and E85.

The dyno tuning was not finalized, the the tuner feels that there is 10-15RWHP left on the combination.

This is 100% SBE.

If you had a Mamo intake it would probably equal (or narrow the high end gap) the high ram but still have better bottom end. The other manifolds are basically tunnel rams.


This is on an Engine Dyno, so roughly 10-12% losses when compared to a DynoJet. So, somewhere around an estimated 663-674RW on a dynojet.

Thats what I’m talking about! If all goes well, I “should” have a dyno sheet to send you late this week to give you an idea of what power we’re making at what peak on the stock runner MSD. Tony is coming up to NorCal in a few days to help me get this car straight, so hopefully I’ll have some good data to send your way so we can get started on the Manifold I sent you in January lol...

This would be sweet if this would turn into someone producing different length runners for the MSD like the Fast 102.

I can modify to the runner length to match your H/C, compression, and exhaust. Not a cookie cutter approach but a custom length.
