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

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

**Kracka** · 03-24-2011

LOL exact opposite when we were doing the IM testing on my IX way back...damn that day was cold.

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.

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

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.

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?

True, the torque was barely lower, only for a few hundred rpms at most, so it shouldn't be too noticeable.

I did a few 2nd gear pulls that felt great. I think the car could be dancing on some different load cells perhaps, tough to know. It's really cold out too which seems to do weird things on my car...like one pull will be awesome then it will seem to fall on its face. This wasn't the best example as I started a bit high for rpms and also stopped short with some knock counts popping up.

I think it will feel awesome once the tune is adjusted for the manifold, then a way better comparison will be had.

This was my dd tune on the graph...I think it was spiking cause of the cold.

So this morning everything was going great. Got up early for cars and coffee meet...was way hung over but had a good time last night... (I was trying to make a silly face...but I think I was pretty drunk too )

Then got in the car to go to the meet and some guy was driving like a tool so this:

Then went to the meet, all was going well, car was running super strong as you can see...then I downshifted into 3rd to race this lexus that wouldn't stop honking at me and right when I engaged third a very very very bad noise happened. So I put it back into 5th and it seemed fine no noise. Then cruised a bit further and the noise came back very faintly and started getting a bit worse but nothing like 3rd gear was so I thought maybe the tranny crapped out...was bound to happen.

So pulled over and then this:

Got the car home and my mechanic buddy listened as I turned the car on and the noise was back very audible and he said shut it off. He said sounds like rod knock from cylinder 2 or 3...

Seriously, WTF! I don't even know what to do now.

**Halon** · 04-02-2011

Ouch, horrible news. You now how the saying goes, you gotta pay to play. Sounds like you're learning the hard way, and really quickly.

Good luck, and us Blainian's like to stick together, so let us know if you need a hand with anything.
