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

Build Summary

The license plate on this Evo says it all, Evil AWD. We had two goals for this build and as far as I can tell we were successful in both regards. The first goal was to fulfill our customer's request which was to take his daily driver and make it into a monster that he could still drive on a daily basis. Thanks to Kasey's time and effort in regards to tuning combined with the proper components we have accomplished just that. Our second goal was to utilize this opportunity (we rarely see builds like this in Minnesota, even though they seem to be so prevalent in other parts of the country) and break some records. Drag racing in February just isn't possible here in Minnesota, so for now dyno numbers will have to suffice ;)

New Stock ECU Horsepower Record as of February 5th, 2010

As far as we can tell 814whp beats the previous stock ECU horsepower record by over 40whp! As you can see below we were also able to reach 806whp at just 38psi, which leads us to believe that there is room to grow :) Look for updates in the near future as we get to spend more and more time in our dyno room with this monster!

Fuel Injector Clinic BlueMax 2150cc Injectors

We just can't say enough about these fuel injectors as they have quite honestly changed the game in regards to power output and driveability. Clearly, they are able to support well over 800whp on E85. The part that you can't see from these dyno charts is the driveability. Here in Minnesota we frequently dip below zero degrees and rarely get above freezing in January / February. With that said, this car starts like a dream! Part throttle and cruise characteristics are similar to what was once only achievable with injectors smaller than 1000cc. Finally, you can have your cake and eat it too when it comes to fuel injectors for the Evo platform!

Special Thanks

We would like to take a moment and thank all of the stock ECU gurus for their time and effort, without their innovation and ambition none of this would be possible! We would also like to thank JestrTuning and JohnBradley for their collaboration efforts during this project!

Dyno Charts

Please note that we have included both STD and SAE correction to keep everyone happy ;) Yes it is cold outside up here in Minnesota, but our dyno room draws air from our 65 degree workshop. Either way, the correction factor takes temperature into consideration.

Heard of this last night..congrats!!!!

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

Badass, but why only k272's and wtf@maf-t? Speed density suckas, dooo it!

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

Badass, Congrats

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

dayum. pretty nice stuff guys

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

Hahaha gm Maf ftw! Awesome numbers!

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

Looks like a sick build. I knew there was a reason I went back to the stock ecu.

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

Thanks for the kind words guys!

In regards to the cams this is an honest to goodness daily driver, did you catch the fact that it has a stock ported intake manifold? We've put 700 miles or so on it at the customer's request and it handles Minnesota winter like a champ!

In regards to the MAFT you would have to speak with Kasey on that one. I believe he chose to stick with what he knows for now so there weren't any variables to prevent us from reaching these goals. However, speed density is definitely going to be a part of our repertoire in the future!

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

Awesome, congrats!

I have to admit, first time I've heard of a MAF-T used on an Evo. With speed density being as easy to set up and reliable as it is I don't understand why that wasn't used.

You don't build an 800WHP+ car to be streetable, put bigger cams in it and make more power. :)

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

This build has been in the works for quite some time to be honest. Speed density was relatively new when we were in the planning stages and we just don't have enough Evo's in the area to get accustomed to the intricacies of speed density :( We have three Evo owners at the shop, but one is down for upgrades, another is trying to sell, and the third is my daily driver! lol

Also, Kasey used this combo the last time he broke the stock ECU record ;)

Kid tested, mother approved.

By that, I mean all the openecu dudes (including JohnBradley) signed off on this...your DD is an 05 isn't it? You need to try this, srsly. I'm working on the IX one next, stay tuned :)

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

Congrats, our car scene is better than you think.

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

Yes, 2005 MR. I realize more and more people are going speed density, and I'm not knocking it at all as it appears to be the future of Evo tuning. It was just one less thing for us to worry about for the time being, and clearly the MAFT combination works ;)

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

I think it mostly has to do with winter as most anyone considering a build like this would have to drive something else 6 months out of the year lol. It just makes me a little bit sad that the first big Evo project to come through my facility was from North Carolina! :lol:

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

Fixed:lol:

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

That thing spools really good. Sweet shit.

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

Watch out, I'll show that to JohnBradley/Aaron@ER, IDK if he'll think that's very funny ;)

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

Good work guys. I agree that a MASS sensor was a good choice for this project. Customer wanted a daily driver with repeatable and dependable results, why not use a MASS sensor over calculations, IAT, and map sensors. Speed density rocks, but you can get a car PERFECT with a MASS when it comes to drive-ability and idle.

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

Ok, I know SD is a big hype right now, but no one has really proven it to be better than using a GM MAF. We are using a 3inch upper IC pipe with a 3.5 GM Maf and I will bet you the restriction is not hurting the power at all or spool for that matter.:beach:

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

And for the time it takes to get SD right (for driveability, not just dyno numbers), you could've spent that time on things that would actually give you gains.
