Tony Mamo, Peak speed, Vengeance Racing, anybody else?
And is the Msd intake better than the Fast 102?

I have one that's ported by hioSSilver. Hard to get a much better job IMO

And the MSD is superior to a fast 102 if you want to be shifting over 7000 rpm

Still debating if i want to get one or not, probably won't shift hardly any higher than 7000. Not sure if its worth it over my ported fast 102.

Same engine — fast 102 vs msd both Mamo ported. Below 6400, fast better. Above 6400, msd better. Out of the box, fast is better. Msd needs a lot of material removed. Properly ported, I prefer msd. Esp with larger cam

Ported MSD if you are spinning the motor north of 7k. Ported Fast for anything else.

Thanks mang

Pm me if you want nmass. Love to help ya make that thing go better.

After looking at that dyno graph im not gonna get the msd. Its not gonna make the most average power where i need it unless i shift at 7500 or so. By then the cam will be way out of its power band. If it made more power from 6000 on up or lower I would be on board with it. Ill see what the fast 102 will do with a cam and maybe in the future look at the msd again or maybe something better will be out. Thanks for the help!!!

MSD is great in its application but not in all applications. Wish fast would nut up and make cathedral mid length runners

nmass399

Exactly, maybe they will get their heads out of their butts and get it done. When they came out with the one's for the ls3 i thought that they would have them for ls1 and ls7 also.

Vengeance racing. I ordered a fast 92 and got a free port job

FWIW I went from 234/242 to 242/248 cam with my already installed Mamo FAST 102 and didn't go any faster, actually a little slower. Then added Mamo MSD and still didn't go any quicker and just a touch more mph. Shift around 7500 on max effort LS1.

I'm gonna switch the cam back and see if it will go quicker. The FAST is hard to beat on most cathedral applications. Altho the MSD does feel stronger revving out it just did not make much of a difference at the track.

BTW I am keeping the MSD for turbocharging next year. It "looks" like it can hand boost a little better than the FAST. We'll see

You running stock throttle body? Stock is good till 450hp. I'm waiting to get my heads and Intake put on. Need throttle body and gonna get roller rockers. My cam specs are .601/.605 113lsa

I seen a guy go from a ls6 intake to a ported fast 92 and gained 20whp. He was returned also.

I went from a ported ls6 to a ported fast 90 and pick up 14whp. So i could see a stock ls6 vs a ported fast picking up 20whp.

BigDZ28

I have 243 heads that lingenfelter cnc ported waiting for roller rockers. Should easily break past 450whp

Nick I also say stay with the 102 if your not going to rev past 7k. I take it no more 12 OH index?

Here is my question.For the substantial investment in these manifolds,how much ET is in 14 or 20 hp? I would make the move from my LS6 but I would be pretty disappointed if I only picked up .05.
