I spoke at length with the crew at Motordyne today and got a whole bunch of questions I had answered. First, it makes more power at all points of the hp and torque curves even with the longer runners which are not as long as the VQ manifold but longer than the stock VHR runners. No matter how I asked, they would not speculate the power output as they will only show the results after independent dyno tests which is smart but at the same time I wish that all dynos will be done on the same rollers to keep the calibrations similar.

In for dyno results!

So $700 for a modified crappy stock plastic manifold. That's a pretty penny for some R&D.

I like what MotorDyne does, but they should have had the manifold re-cast in aluminum with a price point at $1200.

I perosnally would rather it be cheaper for the same amount of power gain. I could care less how it looks.

In comparision, a new VR38 intake collector runs around $650. Then factor in the cost of a retrofit kit... none of us know what the benefits are besides eye candy :)

In for results!

In for dyno sheets.

In for results.

Plastic will not heatsoak like aluminum will, this is probably a result of some R&D but an aluminum manifold would look awefully pretty!

would like to see the data, as with everyone else... and PLEASE don't give us a before and after where the after includes a new exhaust intake and/or tune... just with and without manifold under various conditions all other factors equal, por favor

I think it would be better to leave it composite and cheaper for the wallet and heat soak. If some day down the road they find there is a forced induction limit to how much boost the composite will take, and there is a demand they maybe they could do metal. Then it may not matter as much anyway (intercoolers).

In for results too.

Yup, will do a before dyno with installed mods listed below. The car will come off the dyno and I'll install the manifold...and back on the dyno it will go for the post dyno. Then I'll have the UpRev tune done.

I don't see how it can make more power at all points of the curve. If they are lengthening the runners then theoretically they are giving up a little in the top end in order to get a fatter mid-section. Overall it may be faster but the peak power number won't necessarily read higher. Interested to see the independent dyno comparison.

Subscribed.

Chris is correct on this one. Unless they somehow altered the flow characteristics of the manifold itself and made it better flowing, a difference in the runner length won't produce gains in the powerband without producing power loss in another.

^^ it sounded like they said it switches between long and short runners, RPM depending, to maximize the low and high powerbands.
