Review: Motordyne M370 Manifold w/ Comparisons

OP, 5th gear is 1:1 for the m6. I don't know guys, I'm still not sold. In the OP's case you're looking at the cost of the part, the install, and the retune. I'd estimated you're looking at anywhere between $800-$1000 and you're actually losing a few ponies. Granted the loss is up top but it still seems like a a lot for ~12lbs/tq in a limited window of the powerband...

I'm kinda with you on this one... seems like for something an intake manifold to be worth that much you should gain significant power throughout the entire band. For that price you shouldn't lose anything, anywhere.

I'm not bashing Motordyne at all, I tip my hat to this, it's really interesting that it works like it does, but you'd think it would be a little more significant for the price.

Has anyone cut open the stock intake manifold? I'm sure there has to be some room for improvement over the VQ37 one... instead of reverting back.

5th gear loses power on the dyno, so no 4th gear is closer 1:1

Automatic guys run 5th gear in DS mode which is 1:1.

I still think you're wrong, I did my first dyno run in 4th and it was the lowest reading. All subsequent runs were done in 5th, the only thing that people would want to look out for is to keep from having power cut once the car hits 155mph on the dyno, other then that, 5th gear is a 1:1 ratio.

Gear Ratios (Manual)
1st 3.794
2nd 2.324
3rd 1.624
4th 1.271
5th 1.000
6th 0.794
Reverse 3.446
Final Drive 3.692

You should have to worry about hitting the limiter unless they failed to remove it during the UPRev tune.

He has a g37. maybe its diff in that car.

No, you're right IT IS 1:1 in 5th gear. What I should have said was, I made more power in 4th gear then 5th. For some reason, every dyno I have been to I made 15-20 more whp in 4th gear then 5th.

You're right about hitting the speed limiter in 5th.

Now that I'm dong the analysis, I noticed what looks like a slight RPM calibration issue on the dyno. The car is run to redline but the plots show only 7300~7400 RPM.

...fairly typical dynajet RPM calibration behavior. Maybe the tire size wasn't entered in exactly correct?
The pre/post results are measured the same way so its all good.
