MAP Tubular Manifold Dyno Testing - EvoX
 

Caveots: I don't work for MAP; this is an unbiased review by a car guy that wants nothing more than to make his car faster.

I let MAP borrow my car for a few days for their lil-welder that could (Chris is amazing) to fab up a prototype for their tubular exhaust manifold for the Evo X. I'll be beating the piss out of the car and just generally making sure the thing works so that the product is as good as it can be. There may be some minor revisions but the manifold you see here will be available either cleaned up or ceramic coated.

The thing is really a work of art, I will get more pics of it. The flanges used are amazing CNC pieces and the welding is out of this world. There's not much to say about the product itself other than its built right here in the USA and the quality is nothing short of world-class.

We kept the testing *extremely* simple on this. My X was tuned only a few weeks ago and the tune was untouched throughout the entire process. The car put down 4-5 good baseline pulls before we yanked the stock manifold to get the prototype on. After it was locked and loaded, guess what? We made more dyno pulls! I made them do several to be sure but the results consistent and correct.

Holy crap that can't be right! We poured over the numbers and other dyno plots. The truth was right there in front of us. The car lost about 400rpm in spool. I was a bit disappointed by this to be honest but I feel like it could be helped with some tuning. This manifold utilizes 1.25" runners to avoid being too laggy.

Power. From 6500-8000 the car gained 35+whp. From 7000-8000rpm the car is up a solid 40whp! I was absolutely in shock, this couldn't be possible! But it was...it SO was!

Now, the awesome part. Projects like this can take some time, but I told the guys at MAP that I was going to the drag strip this Saturday come hell or high water. Things ran late as they always do, but they made good on their promise. Friday night at 7pm the car was on the rollers for this test and then I went home to get ready for the trip to the track the next day.

Driveability. The car honestly doesn't feel any laggier, maybe a bit in 2nd gear but cruising around the car feels the same, until you are WOT and in the upper rpm. The car feels SO much better now, its still just as smooth and fun but damn it just rips up top! The car is starting to make enough power now that you start to get that floating feeling when staying in the powerband.

Reliability. I have honestly been the eternal skeptic on tubular manifolds. They all crack, it's easy to just say that. I'll update this thread down the road and let you know how it hangs in there. My hopes are *very* high that it will last for years to come!

*edit* current power mods:
aFe intake w/ perrin inlet
custom 2.5" UICP
custom 3" pte core fmic (not much bigger than stock)
MAP tubular header
CBRD BBX Turbo
MAP O2 Elim Downpipe
Megan Testpipe
Magnaflow Catback
hallman mbc
dw 800cc injectors (BP 93oct)

WOW, nice numbers!

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Wow nice gains! Looks very nice as well, are you going to be having yours ceramic coated?

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Yup I'm going to run it for a few weeks then inspect it for quality control, then it'll get coated and (hopefully) I can find a way to convince them to let me keep it. Whatever they are charging for this thing, it's worth it. I'm low on modding cash right now but if they offered me a deal on it I will probably have to find a way to make sure it stays on my car; its too damn fun!

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Yeah, I expect mine to crack after a few years but all of the good shops have lifetime warranties. That's why I didn't hesitate to buy from Full Race. Go with a company that has a reputation to maintain and has been around for a while. I'm sure this would be a good buy.

I'll give you a piece of DEI cool tape for that sensor on the driver's back side of the motor. I think only the ETS comes close enough to melt it but it costs next to nothing to add some safety.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Thanks man! That was going to be on my todo list; it comes close but not *too* close.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

This beater of yours is coming together way too quick, the Hemi is going to need some upgrades too keep up at this pace.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Very nice

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Thanks for the review sir, and letting us borrow your beater! ;)

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Any chance on a smaller runner design for this mani? And any chance on pricing, maybe in a PM?

This is something I will be looking to do over winter while my car is sitting around the garage.

I am just worried about increasing lag another 300-500 rpms on my setup as it will probably already be nice and laggy.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

This design uses the smaller 1.25" runner instead of 1.5", can't go any smaller sir :( We will be releasing pricing and more information soon :)

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Nice review. Any thoughts on why spool is slower?

Awesome on the power increase!! Any shots of the collector area at all?

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

We're thinking its due to the longer runners, no shots of the collector due to time constraints, but we're building another one this week for pictures, etc :)

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Pick me pick me ;)

Nice, can't wait to see it.

Are you making changes from Scheides version?

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Its for Hollywood actually sir, but we can certainly get you in line next ;) And besides some finish work like polishing or coating we don't plan on any changes.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

If I had any money, I would do it for sure...I am dry already.

He is doing a back to back with a stock mani, your ported mani and the tubular one right?

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

I believe so yes.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

He's a smart cookie so that'll make for some interesting results.

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

Looks really good guys, happy to see you're still developing awesome new products.

Scheides... you and I need to do another roll, maybe this Wed ;)

Re: MAP Tubular Manifold Dyno Testing - EvoX
 

What little increase in lag you might get from a mani like this you'll make up in power gains.
