Anyone running a head ported by MAPerformance? Curious as to the quality, results (flow bench, dyno, etc.)... Did a search and didn't find anything. Thanks in advance.

I have a 2.3L MAP built stroker, MAP ported and polished head, and Rev2 intake... The quality is superb.







E85 tune tomorrow... look for dyno graphs/pics/mod list in a later post.

For the price, quality, and service, you really cannot go wrong with MAPerformance! Top Notch.

Thanks to AQ Motorsports/Harman Motive in Torrance, CA for the final build!

 

Thank you for the kind words sir! I'll see if I can dig up some more reviews for you but this should get you started

MAPerformance / First to break 800whp barrier on stock ECU!

 

I've been running one since last year and I LOVE it!

I've recommended them to my friends, tramendous bang/buck. We just put one on MattD's car too.

Good stuff, worth every (value-oriented) penny!

 

also check out Head Games,.. they port theres a good bit more, what im going with.

No offense to head games as I've heard nothing by good things, but you're mistaken if you think they "port theres a good bit more." We offer 5 different stages to suit just about any application including our record breaking 4g64 in my signature. Back to back testing on this kind of stuff is hard to find and/or pursue but I would be willing to put our cylinder head porting up against anyone in the industry

 

Guaranteed as death and taxes is anyone can take a Dremel to a stock head, give it a cleanup, sharpen some edges, and push it out the door as a 'ported head'. Someone will buy it, flash a few photos showing smooth surfaces, run it, and go around saying, "wowiee, it works great!" Rest assured that some here have received exactly that without realizing it. Even a stock head can be pushed to 1000whp (it's been done), so hp figures don't mean much, unless of course it's a back-to-back dyno test.

When it comes to an EVO head, I'd consider two things - (1)Actual flow data/testing, and (2) hardware. IMO, the Cosworth head was revealed to be an expensive dud in both of these departments. How many were suckered into one of these, and at what cost?

My personal advice for the masses is the same for any similar situation. If one is going to throw any money at it, where available, get a proven CNC port job. By proven, I mean one that is supported by actual before/after flow data and/or dyno testing. With this, one can best be assured that there is no difference between what's advertised and what is delivered ... something that cannot be repeated with comparable accuracy when the work is done by a human hand.

It's your money, your choice.

 

Thanks

 

wow i think that sumarized it right there TedB.

 

Once again TedB has cut straight through all of the mumbo-jumbo right down to the bone!

 

WOW, as i was. just checked out MAPs website. Might end up going with the stage 5 along with rev3 intake mani!

 

The pics do look good though.....another fine looking product from MAP....

 

Thank you for the kind words Although I do agree with Ted B to an extent there is one thing that was not mentioned that plays a big part in CNC portwork, casting shift. You may think that we're splitting hairs but we've seen some pretty big discrepancies from one cylinder head to another that a computer program may or may not be able to recognize and compensate for. We've looked into our own CNC program in the past, and inspected some of the most popular offerings on the market, but we're still doing it by hand as we feel it yields the best final product. In regards to research and development we have done before and after flow testing on several of the stages we offer and there are so many cross sections in Bob's office that it makes me cringe when I think of the value of those cylinder heads if they were complete
