hello everyone,
A few weeks ago i contact with a local dyno, Adams Automotive, about setting up time to get the car on his dyno to compare the Kinetix Velocity Manifold vs a Stock Plenum with a 5/16 Plenum Spacer.

Well today was the day...

Sorry i don't have a lot of pictures I did how ever data log every single pull so if you want to go in and dissect whats going on more power to you. For those who don't know my car is a DE with 11:1, BC Stg 2 Cams, OBX Longtubes, OBX Dual's, MD 5/16 Plenum Spacer, Injen Long Ram Intake 3" tapering down to 2.5", Stock Throttle Body and a Haltech Redbox. This car made 288whp 268wtq at a 1.07 CF a few months ago.

It took about about 3 hours start to finish. We had some problems with the dyno initially with some wheel spin and not correctly calculation engine RPM. Once all of that was figured out we started our tests
.
So the Stock manifold made and average peak of 274whp and 210wtq with an average of 159hp and 188wtq through the pulls. with a 1.00 CF. This was an average of 3 runs. So i was making a little more than than i did but its also 30* cooler than when i initially got tuned.

Now the big surprise of the day the Kinetix numbers 276whp and 218wtq with an average of 172whp and 203wtq through the pull.

Crazy right?

The Kinetix stomps the crap out of the stock through the midrange. Here are the pics i took.

This was the first run for each of the two.



Closest peak runs between the two.




Comparing the under the curve power, look at that difference Dark Blue is Stock manifold and Light Blue is Kinetix

If I had to just make a guess I'd say that large difference was probably due to the cams not liking the stock manifold.

A comparison of those two manifolds with the STOCK cams the numbers are much closer, that difference you posted is HUGE though, +50 tq at 3500 rpm...

All of a sudden I'm rethinking my plan to use stock cams for a daily driver lol.

 

I know your kidding about the swapping out the cams but for those who don't know its quite a chore to change out the cams and you WILL NOT see these results solely on changing the cams.

I'm not sure how the Kinetix makes that kind of power difference but for me i would say in my situation its worth the $700, considering when i boost it that midrange will carry over and be amplified.
