Well testing is all done.

I think Jordan said he'd put the graphs together tomorrow but it was pretty interesting to say the least.

The most interesting part of the manifold that is staying on my car was that my track tune which dyno'd last october at 570whp/455wtq made 562whp/465wtq...but last time it was at like 37psi and this time was at like 32psi...5 psi less and close to the same power and more torque...

Once the tunes are tweaked I think this manifold should be worth some solid gains!

Damn you, more info! MAP long-runner?

Yes, I currently have the MAP long runner on there.

We tested 4 total...I will let Chris release some results tomorrow on the dyno graphs...but I guess if anyone has questions I will answer them. I don't think they have anything to hide.

In for long runner info.

Here is a little info....it's an overlay of boost logs from my car. One is from last October on the stock ported mani, one is from last night with the long runner. Both are my "track tune". The numbers should be pretty close as the baselines were spot on for my regular tune with the stock mani this week vs last october (within 1hp).

Numbers for stock ported were - 564whp/464wtq.
Numbers for long runner were - 562whp/465wtq.

So basically the same damn numbers at way way less boost...next step...bring the boost back up :)

LOL

So how did the MAP long-runner compare vs. the FiD and MAP short-runner?

I could post boost plots of all of them if you want. I don't have all the dyno graphs yet though so it will be tough to say numbers wise.

The FID did provide the least amount of gain over any of the manifolds on the normal tune. But boost was a tad lower. still not near as low as the long runner though.

FWIW when we were tuning my car on the first pull made almost the exact same power as it did last summer, ~340whp, but at only 20psi vs the 28psi it ran last summer. When we turned the boost back up the car hit 400, but with more taper i.e. more to go.

High hopes for this retune are certainly worth having!

So basically exactly what I am seeing ;)

I might be trying your MBC/3 port setup to reduce wastegate duty cycle up top to see if we can get more outta it. I asked Shane what he thought was the best option, MBC, Forge wga (which i know he hates, but has a 25psi spring) or cranking down my blouch one more on the preload as it has lots of thread for preloading.

well here are general spool numbers. I don't have the numbers to go with each of these runs so its hard to say anything conclusively, but here are the rough spool numbers. (I kinda chose them at random from the groups of runs).
