That's how I understood it, hence my comment.

Close no doubt, but 2psi can make 20hp difference at your power level.

And we (MAP) didn't touch a laptop throughout the entire process, can you imagine that? We did turn up the heat in the shop to approximately 150 degrees during the FID testing though

Yea I was sweating like a pig for those runs..

MAP's Evo X Exhaust Manifold Testing / Dyno Results

FattyBoomBatty · 03-24-2011

I like how the test was performed, and I believe you guys (MAP and Dave). But can we get some pictures? I especially want to see the old style long runner and revised versions right next to each other. I want to see what made a 10hp difference.

**Murlo26** · 03-24-2011

Like I said, I didn't take any pictures of either manifold, Chris would have to take these pics. They still have these manifolds.

**v8klla** · 03-25-2011

I will have some up shortly.

**Murlo26** · 03-25-2011

Picked up the car today from MAP.

The car doesn't really feel any laggier and spool doesn't feel any worse really, the car still feels peppy.

Can't wait for a full retune to see what it can do now!

**goodhart** · 03-25-2011

So which manifold is on the car right now?

**Murlo26** · 03-25-2011

Scheides' old one, the original MAP long Runner one. That's why we tested it last because that was actually mine.

turbotalon1g · 03-25-2011

Are you tune up your street tune? or F&F mode race tune?

**Murlo26** · 03-25-2011

I am confused, are you asking which tune the test was on or which tune am I going to get re-tuned?

Excuse him, he's ESL.

MAP Long Runner at the bottom, followed by our Revised Long Runner and then FID moving upwards.

Looks good!

**Murlo26** · 03-29-2011

Well...been starting to beat on the car a little bit really watching for knock...had to stop this pull at lunch due to a bit of knock (spool up) but you can still see the street spool on the MAP mani...seems to of taken about 400-500rpms of spool out on the setup and it is quite noticeable on the street. Top end seems more scary now though which is good and what I was going for but I am hoping some mivec tuning can pep up the midrange again.

It was cold out so boost seems to be up too...

**v8klla** · 03-29-2011

If you look closely at the graphs spool did suffer on the long runners (including FID) but on the dyno the horespower and torque did not, perhaps better efficiency creating the same power at lower boost levels?
