The seals are good for 13 PSI safely. What was the last factory spec for the 3rd gen, 12? We are running 6-7 PSI right now. So, time will only tell....

For me, I'm going this route: Racing Beat Intake, Headers, Rotary Performance Super CAT Midpipe, Racing Beat Catback Exhaust. Then, I will have a mild street port done. The runners are in terrible shape, and we are getting 15 RWHP currently, but a little more work could reveal close to 50 RWHP out of porting alone.

Summary:
JDM Original RX8 247HP at the crank (Assume 20% loss = 197 RWHP)
USDM RX8 238HP at the crank (Assume 20% loss = 190 RWHP)
RX8Club Member RX8's make 210-220 HP at the crank (Assumine 20% loss = 168-176 RWHP)

Intake +2-5 RWHP
Header +2-5 RWHP
Street Legal Mid Pipe/CAT +5-7 RWHP
Offroad Race Mide Pipe +8-9 RWHP
CAT Back Exhaust +3-4 RWHP
Flywheel +2-8 RWHP*
Under Drive Pulleys +5-8 RWHP
Grounding Wires +0-1 RWHP
Street Porting +10-15 RWHP
Piggy Back ECU +20-40 RWHP
Turbocharger +50-60 RWHP (GReddy Dynoed @ 240 RWHP)
Supercharger +30-50 RWHP
Nitrous +50-75 RWHP

I dynoed 187 RWHP uncorrected the other day, and 180.5 SAE corrected. All I had was the Racing Beat Catback on the car. Now I have more mods, so back to the dyno for me...

Ray Wilson of PFS has already done so with Ryans E-manage. I must say the stock tuning on that E-manage did not run very good. Lots of break up at 6k under boost. As I mentioned though Ray already erased the stock maps and reprogrammed the unit with his own maps. I think they still have a little fine tuning to go but Rays first map was a world of differnec over the greddy maps. The RX8 felt very strong on a basic PFS tune at spring rate.

Real easy solution here guys...........Stand alone engine mgmt.!! Tec 3 or whatever. Just eliminate the stock ecu and your done.

the stock ecu controls too many things on the car

You don't know much about stand alone's then.........A good stand alone will control everything your standard ecu does, but twice as well and twice the features, hense the reason people run them....lol.....

you don't know much about the RX-8's PCM then.......

I seriously don't see the need though when all you really need is to take your car to someone who actually knows what they are doing like Ray Wilson of PFS.

Uh, no. That would be me, not Ray.

Ryan is running one of my maps at the moment. We played around with for a while on Wednesday again, but we think his persistant CAT CEL is an indication of what is f-ing with the tuning.
The OEM PCM is pulling a lot of LONGTFT (-17% or more), which is making it lean under load. This seems to be related to what the PCM sees as a rich condition due to the NBO2S never making it into the proper range under closed loop.
The Greddy kit has some sort of dongle spliced into the harness that is supposed to kick it out of closed loop at some throttle setting or something similar. I haven't had a warm, well lit moment to spy on it yet, so I don't really know what is up.
We will (hopefully) get it on the dyno later today (Friday) and I can give it a poke with a sharp stick.

I guarantee Ray could make it perfect in half the time with the Tec3.

I guarantee I could make it make it perfect in half the time with a Tec3.

However, that is way out of the budget at the moment. When Ryan wants to spend the extra $2700 or so to replace the E-Manage, I'm sure he will jump right on it.

I know I would love to use the Tec3 on my car also. However, the fact is that my car is running perfectly at the moment - and I'm running even more boost - so a stand-alone would be superflous for my application.

So, the goal is to learn what is impeding Ryan's setup from working perfectly and fix it. I'm not the type to throw the baby out with the bath water.

I have been amazed at the deals I get on used gear. Guys who can't get something to work and get frustrated, then sell it for junk to buy a more expensive toy they hope will solve their problem.
I guess electronics are cheaper than talent.

The RX-s's ECU is just way to involved in this car is part of the problem. Its more smart then its own being. A factor t olook at is this car can not be dynod or should I say properly without a stand alone manager. The ECU retards the timing if all 4 wheels are not spinning and at a certain speed differenchal. I balive it is 15 degrees. So your HP rating will be way off on the dyno. There was more but ben a wile I stoped folling with my 8 and demoded it back to stock. The K&N intake is horse **** caused my ignition to miss but yea I was modding when there was no exsisting upgrades realy. I wanted to go with the Blitz SC kit. To mod this car right you need a stand alone!

This is actually a myth that began when people were getting low dyno numbers and wanted an answer that wasn't the truth - the power is just plain low.

The DSC/TCS system will throw a light if the wheels are spinning at different rates, but the ECU will not pull any throttle or timing or dump any fuel as long as the TCS/DSC is turned off.
Max WOT timing is around 30° on or off the dyno.
