ITS STOCK

Well I finally got a chance to put on my Mamo msd and get a tune. The gains were pretty impressive over the ported fast I had on there. The car just pulls like a raped ape now all the way to 7k. After the tune we went straight to Cecil to try and get some passes in made one pass off the trailer babying out of the whole to test the prep out and car went 10.22 at 140mph with a slight miss up top. Every pass after that the miss up top got worse and worse. I did some messing around and think I fixed the miss (valve float). Now just to get back to the track and get that 9 second pass. I'm pretty confident the car will go 142-143mph on motor in some good air.

What all is done to your Z06??

ITS STOCK

It's got rpm heads and cam package, arh 2" longtubes, haltech cf112, udp, mantic twin, and Mamo msd

Very nice gains and the Results speak for themselves.

ITS STOCK

Thank you sir can't wait to give it another try

What was the TB on the FAST? Same for MSD?

ITS STOCK

It was a nw 102 on both

26rwhp over a ported fast is amazing. How much did you pick up in the 1320?

ITS STOCK

I don't really want to say since I was never able to get a clean pass with the fast due to bad track prep but it did go 10.41 at 139mph and it just barely hit 139. The 140mph with the msd was with a slight miss so I'm pretty confident it would have gone at a bare minimum 141mph. Later in the night when the air started getting good it probably would have gone 142-143

That's amazing. Proof is in the pudding. Guess we now have an answer on the ported fast vs ported mamo msd.

...still need the stock MSD vs Ported MSD.

There is the pudding.

NachosZO6

Point well taken. But for people with ported Fasts, this is something they'll need to consider now.

Da Z06

I agree.

The thing is that we all know that the MSD will outshine the FAST and obviously the stock intake but still have not seen the stock MSD vs ported MSD. Personally, that is the only way to justify the $$$ for a port job on the MSD.

NachosZO6

Very intriguing because I know of a very well respected shop/vendor on here who doesn't touch the MSD intakes and are still making great numbers.

Da Z06

Correct. I personally run the MSD with a NW102, MF108, stock TSP ported heads, middle of the pack cam (about the same as the K501) and was good for 593RW on 93 octane. So yes, as "cast" the MSD is a power making machine.

Congrats on a well sorted combination. Any N/A LS7 trapping 140+ is definitely working!

B3 cam?

Solid gains!

Tony @ Mamo Motorsports

Awesome results!!

Once you get the miss sorted out and a little more track time I suspect you will bump your previous PB by 2+ MPH which takes a good bump in power at this level as most of you that spend some time at the track already know.

I helped another customer recently that also tested against a ported FAST and he picked very similar gains moving to one of my ported MSD intakes

I have been telling folks inquiring that I estimated a 20+ RWHP gain from a ported FAST to my ported MSD which is significant. Especially knowing a ported FAST is easily 10-15 over a stock intake if done properly.

Here are the results from that test.....please excuse the fact I had to print two pages and overlay them and take a picture. I was sent the information in two halves and wanted the results to be easier for you guys to quickly glance at. I dont know the exact specifics of the rest of his mods but this is a Mamo ported FAST versus a Mamo ported MSD ....a gain of about 24 RWHP




So the OP's results now represent the 2nd independent dyno test that back and validate my thoughts that a properly ported MSD is worth 20+ more than a ported FAST. I believe you guys will see a handful more soon.....don't know what the results will be but I suspect something similar.

Oh....here is a good test done by a shop most of you know and respect showing a stock MSD not nearly looking as strong.....and there are many other stock MSD tests that looked similar only showing modest gains in general if you take the time to look

The right approach to the porting clearly helps these intakes perform....as it does in just about every other high performance internal combustion engine. Better more optimized heads make more power.....better more optimized intake manifolds make more power....it wont be different next week, next year, or in the next decade. An engine is an air pump that converts oxygen and fuel into cylinder pressure.....the more optimized you make the flow paths the more power your going to ultimately produce.

Wow.. Great results!!
