The EMS does not know what gear the car is in so it just supplies an amount of fuel based on RPM and load. If these conditions are met, then the car should get richer as the temps get hotter because it know no different.

There are modifiers in the EMS to compensate for these conditions. You could set a modifier to pull x% of fuel out as air temps rise. This would allow you to keep the A/F more consistent through each gear.
I never noticed this effect myself, but that is probably because I have O2 feedback turned on. The O2 feedback with the AEM EMS is fast enough responding and accurate enough for use at WOT heavy load.... I love this system

Seth,

No, the set up in the white car is using the HKS 280 cams.

The difference in AFR's as the gears go up is not from air temp. You can test that by making a pull just in one of the higher gears, you'll find the AFR's are the same as if you did all the gears first.

Ported intake manifold, $75
BR 65mm throttle body, $300
Ported exhaust manifold, 02 housing and turbine housing, $300.

This is what is making the power in the car, total is $6505.
On the website, the ported exhaust manifold, the ported O2 housing and the ported turbine housing are $225 each, so $675 rather than $300. Which one is right?

Yes, $225 each if they are ported and coated. If you just want them ported it is $300.

For now the RS is finished, finally, on the dyno. The car has over 450 dyno pulls on it. I was at 396 when the dyno computer crashed. I have used two laptops and one other desktop to run the dyno since then. I will have to add up exactly how many runs I have now.

Beautiful things. The engine is as good as it was when I started. The head gasket is as good as it was when I started. In 450 pulls I have yet to hurt a single thing on this car. The head, shortblock, all fasteners including the stock head bolts are in it and they have never been re-torqued.

The car has over 200, 370+ whp pulls on it. I have tried to tweak the stock combination as far as I SAFELY can. I would not be afraid to give the AEM EMS tune I am running to any customer that is running 94 octane in their personal EVO with this same set up.

Knock voltages are below 1.7 volts. For those of you tuning and logging that you understand how safe it still it.

The car has seen 30 psi of boost on pump gas and has never had ANY race fuel in it at all. I have no intention of running race gas in this RS, ever, at this point. Easy additional horsepower if I did. The timing is set to 0 anything over 25 psi, another indication to how safe this car is tuned. Also explains why I have managed to run it completely unhurt for so many runs.

I ended with a best of 393 whp and just over 380 ft lbs of torque being the best.

I have found NO difference in swapping compressor housings on this car. The TME and standard EVO seem to be the same to me.

The 10.5 housings found on the TME and on the MR are the same as far as performance goes. No difference. No difference in boost control that I can see either, even with the different design on the wastegates. The 10.5, with additional tuning is worth some extra HP. I am going to say possibly as much as 15-20. You would have to tune to get this though. A car that was set up with a flash that was seeing some timing being pulled because of knock might benefit from these housings too, as I believe the timing would not be pulled as much or at all running these 10.5's.

COMBINATION. That is what I have to say about these 44 pages of testing. COMBINATION. You can throw parts at a car and tons of money. I have always said we build parts that work and work together. This dyno thread has proven this. I think I have also shown I won't just sell a part if it doesn't work to make money. I have pissed off some other vendors with this thread and have been left with stock on my own shelves because of it. I have also benefited greatly from this and all of you that have read it and bought from us because of it. COMBINATION. You guys have to get things that work together to get the best results.

The stock turbo/engine is extremely hard to beat on pump gas for a daily driver. We are talking WHP numbers here that should be able to run 11.50's in the 1/4 mile on PUMP gas and have instant spool up. That is freaking respectable.

The car ended up having the following parts on it to make the WHP that it has:

Our complete Stage 4 kit, including 680 cc injectors, HKS 280 camshafts, BR lightweight muffler and offroad pipe, deluxe upper i/c pipe, deluxe FMIC and Tial BOV.

Our ported intake manifold and 65 mm throttle body.

Our ported and ceramic coated turbine housing (10.5), O2 housing and exhaust manifold.

AEM EMS.

Exedy clutch.

That's it. All of these things are available through us and as I said there have been no tricks. This should be able to be duplicated on any EVO on the same quality pump gas and tune.

Actually, if you guys remember this particular RS started out weaker than our Red EVO. The RS started and remained about 20 whp behind, with 236 whp compared to 256 on the red car. This makes me believe this package can be duplicated on a typical EVO even more.

Tomorrow the car goes back to AWD and gets the brakes and suspension done on it for this Friday's race and Car and Driver testing to begin. I can't wait to drive this on the street!!

Take care and enjoy your cars.

wanted a clarification... cuz it basically looks like all this power on the stock turbo is great... but the limiting factor is prolly still the compressor wheel.

so... are you headed down the path of offering the old 20g wtih a new br cast mani (different flange) or are the 20g wheels going to be cast for the reverse scroll in ti/al like we're all excited for?

and a quick kicker question... with the 20g we should see less problems holding boost right? so that could mean less wastegate tinkering/hassles ?

crap you answered in the other thread... my bad....

Was this with the 264/264 cams?
You forgot labor (unless you can do all that stuff yourself, including tuning the AEM EMS).

Someone correct me if I'm wrong, but I think labor is included on a lot of that. I think $2400 for the AEM EMS does include tuning.

These prices do not include labor. But the $2400 for the AEM EMS does include tuning. One part this is missing is the Exedy Clutch, its $1500. With that kind of power a new clutch would probably be in order.

HOLY SHEEEET! This car is bad. I can't wait to see what it runs on Friday. The spool up on this car is crazy.

We found a boost leak when we were putting the car back to AWD. There was a stripped bolt in the compressor housing flange. I was seeing up to 24 psi spikes to try and get the boost to hold 18 psi on the dyno. On the street even with the leak fixed the boost still will not hold over 18 psi at 7500 but damn does this car pull hard.

I will be very surprised if it doesn't run mid 11's on pump gas tomorrow at the shootout.

Also after a year and half of fighting our red shop car and a mysterious misfire that has been in it I believe we have finally found it and it is running well. Maybe we can finally drop it into the 10's where it should have been running long ago.

Conquest made record power too.

I am praying for a good weekend for your shop. Those of you that can make it down for the race on Friday or the show on Saturday should really try to come.

BTW, the prices I posted did not include labor, other than the AEM EMS which includes tuning. I also did not put in a clutch as there are some other options out there that will work too that are less expensive than what I chose in my car.
