so in all of those graphs the msd just gets killed?
even upstairs
so different from the graphs that matt posted at the beginning of this post...
what are those graphs of exactly?
I guess the msd is just a HUGE waste of money?

I think the conclusion here is that the ported MSD with bigger throttle body is worth it if you are doing H/C and will make more power than a ported stock intake with H/C. If not doing H/C, stick with the ported stock stuff. Is that accurate?

[PRAY]

The difference is the stock stuff being ported vs not.

On a full tilt bolt on car the ported MSD/95mm will be marginally quicker. Roughly .1 and 1 mph in the 1/4 maybe. On the street things seem to ven out a little more.

On a H/C car it's a killer. Except no substitute. No matter what though, get your MSD ported. I have been saying this for over 2 years now. Where you spend your money is up to you.

H/C stands for heads and cam

What is H/C?

Stock ported manifold and throttle body are about equal to ported MSD and 95mm throttle body on a bolt on car. Once you go to heads and cam, probably just a cam even, the ported MSD and 95mm throttle body will have a huge advantage.

Yes it will do something, like add some horsepower, but you will want tuning to get the best out of it in my opinion. Not just ECM tuning, but TCM too, if your car has an A8. My stock TCM was only reaching about 5800 or 5900 rpm in 1st gear with drag radials. When it was doing that, I wasn't really noticing a gain from the MSD on the dragstrip at first (still had 87 tb then and stock airbox), likely because it was not enough rpm to make proper use of the manifold's characteristics. Now that HPT can unlock 2017+ TCMs, with some tuning, it is doing something for sure. My bolt-on SS now has a non-ported 95 tb on the non-ported MSD. Using those parts, along with a CAI, E85 tune, drag pack, and a little weight reduction, it ran 10.88 on the dragstrip. Car has a completely stock exhaust system, stock torque converter, stock rear gears, no underdrive pulley, no carbon driveshaft, and no lightweight drag brakes, just to let you know the mod level.

If you're not into drag racing, the short version of my point is, the engine needs to be run in the proper rpm range where the parts work their best if you want to get what they have to offer.

TCM tuning is a most no matter what.

Here is what a stock ported IM/TB is capable of. Stock brakes, DS, converter, gears, blah, blah, blah.



And if you are M6 then the ported Stock IM/TB works just as well. This is the record M6 car. RF dry, Headers, E85, my tuning. Stock clutch, DS, brakes, seats, blah, blah, blah.

so how does a ported msd stack up against ported stock manifold, do you still lose out downstairs...

and I was wondering if matt could chime in here since this is his thread and according to his dyno the msd killed the stock manifold all the way through the rev range...

[PRAY]

I haven't paid a lick of attention to whose thread it was. My bad Matt. I am out.

Point is, these cars will get into the 10's Bolt-on only with the stock IM/TB with the right porting and tuning. How much deeper into the 10's, if any, will they get with PRAY ported MSD/95mm? I'll let you know.

That is really amazing considering the DA and little river (raced there many many many times), can have spotty track prep

You're right oldman, these cars are amazing and Little River is always a crap shoot (and a bit scary I might add), but that night she was good to me.

I have not done a dyno session with a ported stock manifold vs a ported MSD manifold here in house. The only dyno comparison I have to offer that we performed ourselves is the one that I posted at the start of the thread. The MSD did make more power everywhere out of the box vs a stock manifold. Then we did the swap to the 95mm TB and it picked up everywhere again.

I'm not gonna lie, I don't race my 6th gen because I have another car that I race. I got my car just for making products and dyno testing. Plus they are badass cars to cruise and drive. I have have been working on something new for the MSD manifold and I have not been able to test it yet. I hope to have something to show from my absence in a few months.

[Ventmaster]

Thanks Matt, its good to hear from you and the reassurance is appreciated.

[biker2k]

thanx matt..
I knew I wasn't crazy ..
I've seen many dyno runs where the msd is equivalent to stock and really shines upstairs... as far as ported vs ported I guess I haven't seen too much on that, I am assuming ported msd is the way to go... especially with long tubes and even more so with cam and heads..
