Brent and his "200whp club" have been loyal customers for quite awhile. After having gone through the full build with his 1G Eclipse and seeing the car grow, an unfortunate traffic accident left him with a need to build a new car. Brent was a little further along in life this time so a 2011 Evo X GSR was located and the mod strategy began-

It had to be quiet

It had to make over 450whp

It had to be on pumpgas

Since this left us alot of room to build we came up with the following mod list-

2011GSR

ETS 3582R (non-hta) turbo kit with downpipe
ETS 4" intercooler with piping
ETS Testpipe
FIC 900cc injectors
ER testpipe dump
ER double pumper
ER 4" intake with 4" K&N filter
Stock Evo X Catback

The end result looks something like this-



So it was time for the dyno. I did a few baseline pulls with the MAF and got a strong result with a stock MAF-



The stock MAF housing maxed out at 5v around 7600 and 27psi and threw a code. Something needed to be done so it was time to experiment with full SD and the engine bay was switched to full SD as pictured above.

Here is the comparison almost boost for boost-



Of course I can't take credit for the SD programming, that was all Tephra from almost a year ago. After a few attempts back last March, I just couldnt get it to work the way I wanted and then forgot about it until recently. When Brent decided to bring the car back for some suspension work we decided to give it a go. Its sad really because the SD was flawless I just had other issues that I didnt realise until later. A few weeks turned into almost 6 months before I learned how to benchflash cars and decided that returning to SD was in the cards.

I am looking forward to seeing how this will work on other X's in our stable.

way too laggy, look at the lack of torque under 4000 rpms, i would hate to drive this on the street and have to constantly downshift to move. this isnt a high compression honda motor, it needs the boost down low!

 

I should have known someone would comment on that . On the street or in 4th on the dyno the car will make 19psi at 4200. You dont notice the lag on the street, but then again I drive completely different than most people. Driving around at low speed and 3500rpm isnt that annoying and grabbing a gear fast is pretty easy.

You should know better by now. I'm sure some other online specialist will throw another E rock shortly.....

 

has over 3000rpm of powerband. looks good to me.

 

i was reading about this the other day. guys are disabling the map sensor at idle and using the MAF for vacuum and idling.

so just disable the MAF alltogether, tap the maf wires into a IAT sensor or maybe the evo X has something similar to the evo 8/9 with fuel temp sensor that can be utilized instead of maf signal wires for IAT.

use map for tuning and done. i laugh everytime i see a huge turbo sucking through a maf aka straw, when it can be sucking through a pipe.

 

This is all electronic. It does require the MAF to be left plugged in for the time being but it can be out of the air stream and isnt used for calculations from what I can see.

 

ok. going to pm you instead.

 

Aaron, not sure how many of these have you tried before but many of the cars that started as "full SD" have since converted. Jon (bakaunchi) has mine tuned with anything below ~120 load as using the MAF calculations then anything above using straight SD, it works awesome.

Most people found the idle and cruise to be much more stable doing it this way and people got drivability issues doing full SD.

Also with the Evo X we have hotwire MAF's so I don't think they are really a restriction on the intake.

 

Murlo-

They arent much of a restriction but this had been a stock MAF housing as well. Its pure SD with no apparent issues. Cold start, idle, cruise, WOT are all exactly what I would expect and demand from an 8/9. I did play with the MAP tables below 100kpa a little to smooth things out but it wasnt crazy.

 

Yea I can't comment too much, it could be because many of us have 3" or even 3.5" (like me) MAF housings, but I just know many people eventually saw some sort of adverse effects to all SD. I'd have to ask Jon again what he saw because he tried full SD a while back with Tephra then starting doing the hybrid system.

Either way, glad it worked well on this car, its awesome when stuff is nice and smooth!

 

Nice work Aaron! Cool vid as well.

 

nice powa for sure

 

whats the point of putting such a big turbo 35r on a stock low compression 2.0 engine? i dont get it

 

its really not a huge turbo. 3586 maybe. its so you can make 500 on pump gas and have room for more if needed
