Just got back from the dyno session at AEM. The car made 340 at the wheels at 13.5 psi with no ignition issues. We didnt get any breaking up till we got to 28 psi. At that point Jason Siebels of AEM did the mod to the circuit board that fixes the ignition issues some were having at high boost levels. All it involves is clipping off two little electronical thingys (actual technical term yes) on the board. That got us to 32 psi. We got a little more ignition break up at that point so I took out the stock plugs with the stock gap that had 9,500 miles on them. Put in some B8EVs gapped at .025" and it ran clean at 32 psi. 519.5 hp to the wheels fine.


If you have an early box, contact AEM (you may even need to use a [gasp] telephone [/gasp] to do it. They will take care of you.

Most notably:
Stock coils, stock ignition, stock plug wires, stock ignitor.

Damn, I am now more convinced than ever to get the AEM EMS!

Looking at the dyno charts you seem to be spinning the engine up to 8K RPM. Does the stock valve train seem to be working well with the HKS 272's at that RPM?

Thanks,

Keith <----RRE head on GVR-4...for sale!

 

Yes, 8k rpm on dead stock valve train. We've been doing that on DSMs for years. I'll try 8.5k after the LA Auto Show. I have to get it cleaned up, pimped out and drop off the car at MMSA on Friday.

Is that only a 2 wheel dyno i see?

 

Mike,

Nice numbers, very impressive.

 

Yes, yes it is. How many wheel dyno did you want to see?

I can use the 2WD dyno fo free. Takes about 2 hrs to switch the car to 2WD so for extended dyno testing it is cheaper by far.

Unfortunately by dynoing in 2WD on a Dynojet we can only compare numbers with virtually every other dyno chart in the free world. To compare numbers on some of the AWD dynos out there, subtract 40 to 200 hp depending on the dyno I guess :-P

[img]that 2 wheel dyno stuff has proven to be bs make that power on a 4 wheel dyno

 

This is a tuner forum, not a "my dick is bigger than yours on this dyno, so you used the wrong one" thread!

The point of the thread was that AEM is supporting the EMS and listening to the problems people were having with the ignition on the stock coils.

In other words, swing on some other tuners nuts all you want but I will NOT stand for anyone bad mouthing RRE on these boards.

Now screw off and leave the conversation to the adults.

Yup, I know you can do it with the DSM valve train...but I was wondering about ours in the EVO since Dave Buschur measured the valve spring streangth and they are much weaker than DSM valve springs....but our valves are so much lighter than DSM valves so that works out, just wondering how it works at higher RPM than stock with higher lift cams....looks like it works out to at least 8K

Have you had a chance to get ahold of some EVO rods for testing yet? From what I hear they look exactly the same as 2G rods but are forged instead of cast so should be much stronger. I am thinking EVO rods will be the new standard in rod upgrades for 7 bolt motors if they can be sourced cheap enough.

i made 290 at da wheelz on dis same car with only a three inch exhaust and a filter and an intercooler and a boost controller on a awd dyno dynamics dyno with no tuning or punctuation but if you drink the koolaide and it bugs u then just do like i said and subtract 40 to 200 hp from the 2wd dynojet numbers depending on who turns what knob and stuff

Hi Mike, good to hear

Nice job Mike,

What turbo are you using? BTW I see the sequential shifter made it into the EVO!

Martin

 

I'm assuming that's JN (the AEM tech).

I have to say I'm pretty shocked you use a 2w dyno too, but hey...whatever works, right?

And since I hadn't noticed you'd joined up, welcome to the forums!

(I'm assuming you don't remember me, but I'm the guy on the AEM Power tech forums you helped with the Lancer EMS. Thanks again.)

 

What kind of injector duty cycle are you running on those 660cc injectors? My goals are 400 HP on pump gas and between 500 and 550 HP on race fuel and I was wondering if 660's would be a good choice.

Thanks,

Keith

 

HEY MIKE : are you selling this AEM EMS? and if so how much for on this website?
