There is something else I'd like to point out. The stock RX does not make power beyond 5800rpm or so. Remember the severe drop in power/torque just before 6000rpm with the stock header and exhaust piping on a couple people's cars? How can this car run all the way up to 6500rpm?

I own a 1988 RX turbo and it has been dyno'd on an AWD dyno. Unless my ECU is 'bad', it does not make the same numbers as this high strung 'stock' on that Will posted about. So the 1988 ECU thing can be tossed to the wind.

Nice video! Great sound! What rpm do you shift at going from 2nd to 3rd gear? 2nd gear seems mighty short.

Between 2500 and 3500, what was his air/fuel ratio like? Air fuel ratios in the 14 -15 to 1 range can make a spike like that. I'm surprised he was able to start dynoing at 1000rpm. ??

I have a theory. If his intake is stock, stock timing, stock boost checked with gauge and stock exhaust with no excessive leaks....then he's making power by (Drumroll) He has excessive carbon built up in one or more of his pistons. Excessive carbon buid up will raise cylinder temps and pressure and make more power than stock. However, this will push him closer to his detonation threshold once he begains to raise the boost. His compression is higher due to the extra carbon built up. That's my take on this. I'll take it a step further and say this may even be causing his dyno chart not to be that smooth up high. See how funky the lines are? This is the same thing your dyno (Will) was doing when you increase the boost in your past dyno charts. Detonation/Pinging/Knocking.....one of those. I dunno! Just a thought.

Late model RX turbos = Teh Heavy!

Why not me? I want a turbo 6. me, Me, Me, ME, ME!!! I posted this quote at the XT6.net site. Do you peeps think the math holds true? "Speaking of possibilities (bringing back an old post), there is a dyno put up today by a guy named Will at USMB. He dyno'd an EA82T with an intake, TWE header/downpipe, boost controller and intercooler. Here is his result: http://consumer.inkfrog.com/pix/WJM/rx_all_runs.jpg At 14psi he got 142.08hp and 182.20lb-ft of torque. At 15psi he got 161.68hp and 205.63lbs-ft of torque. This is with an assumed drivetrain loss of 30%. If this is the case, then at 15psi he's making approximately 230hp and 293lb-ft of torque at the crank. Not bad at all. Fast forward to us turbocharing our XT6s with the same stock compression ratio as the EA82T engine (7.7:1). Take (230hp/4)*6 and (293lb-ft/4) * 6. See what I'm getting at? 345hp and 440lb-ft of torque at the crank. Just something for us to ponder over and dream about."

Dyno charts, Oooohhh! You should post that in it's own thread. Air-Water intercooler dyno tested. I really like your air/fuel ratio. How did you establish that so even and rich across the rev range? Did you do something to add fuel or is that stock setting? Also, what's the hiccup at 5900rpm?

1st gear, *Scratching underarms* 2nd gear, *Yaaawwwwnnnn* 3rd gear, *ZZZZZZZZzzzzzzzzzzz*

If it is as slow as mine, you can wait. Lol! I just dragged mine this past Sunday. SLOW!!!! http://xt6.net/forum/viewtopic.php?t=4746

I was wondering what happened to the DYNO information you were supposed to post. Seriously! What's going on? ?????

Your rocco had a nice amount of torque down low.

Matt said earlier....

Nice clip! I never heard of any Subarus sounding like that. I thought it was another car until I played it the second time. My RX turbo has a totally different sound to it.

I'm always interested in dyno numbers. I'm betting you will put down around 50hp tops if your car is healthy. At least it is a start and you can monitor how much hp and torque you put down after doing any modifications. What are your plans after the dyno runs?

J/K How much does that wagon weigh stock? An EJ25 into a 2400lbs Scooby would be REALLY nice. This is still a significant gain in hp/torque though.

Forizzle! Dat Doohickey got to Bloody Crackin' -N- Crushin'.

Where's your water tank for the water? Looks like a hose coming off of the water pump. Is it going directly back into the cooling system?

Very Very interesting Will. I would not be surprised if that gain is on the low end. I'll take a stab and say it is just before and just after 3000rpm. Am I right? **Crossing Fingers*** Oh yeah, I got the version 2 you want in my garage. I took this pic last week. Muhahahaha! Now where are those Dyno charts damn it! I hate waiting for those things. I'm a dyno chart junkie.

Thanks for the updates Matty. I for one have been looking forward to see how you and another person is doing on here (Turbo something). Very nice times! I want to join in the fun soooo bad but my driving skills suck with a manual (like how can u suck with an auto right?). Anyways, keep us updated as to what broke. Oh yeah, what happened on your first run? You had a great 60ft time but a slower trap speed. Why?

So if you change to a lighter weight pulley on a dyno and measure more power after the change, it is not a physical reality that you have more hp to use? You mean, even if this difference it measureable on the dragstrip as well, you do not have more power available to use? Note: I didn't say more horsepower but more power that is available to use (to accelerate the car).

Ultimate all-around or ultimate in certain areas like straight line or around cones? Straight line should be easy to pick as that would be who has the fastest RX at the dragstrip. Who is it at the moment? On this board anyways? I'll never be, at least not in my manual trannied RX. I baby it too much off the line in fear of tearing up my tranny. I wouldn't be worried about this in an automatic.

U r no longer playin' the EA82T game? Damn! Another one bites the dust.

A lightweight pulley will allow more power to turn the wheels instead of turning the crank pulley. Having more power available to accelerate the wheels rather than the crank pulley is useful. The 2nd advantage to having a lightweight crank pulley is that it eliminates the rubber bushing thingamajigga that fails on the stock crank pulleys on a lot of the XT6s. I haven't experienced a failure of an XT6 crank pulley since I luckily got an aftermarket crank pulley from two different companies but I have read about it from posts from other XT6 owners. $$$ spent on having more power available to the wheels and added reliability is a double plus. Here is a thread I started on an aftermarket crank pulley and the difference between the stock and aftermarket one. http://xt6.net/forum/viewtopic.php?t=2958&postdays=0&postorder=asc&start=0 Here are some pics of the weight difference between the two. Stock XT6 crank pulley weight: ProECM XT6 Pulley weight: Sorry for getting off the turbo XT6 topic. I am with you on this one though. I've been wanting to turbo my XT6 for years. I'm awaiting Gary or someone else to complete it first. I get passionate about it for a few weeks, then it dies down and comes back again. Good luck!

I don't understand this question? You mean in a wreck? Where did this come from.
