That XT6 does sound nice. Nice videos!

Nice work Will!

I didn't take into consideration that our cars are boosted. The bypass wouldn't work because boost pressure would blow out of the bypass tube. Hrrmm, I'll think further on this.

At SVX Network Site: http://www.subaru-svx.net/forum/showthread.php?t=29386&page=1 Thoughts, comments? Perhaps a valve can be installed in the line to regulate how much air gets bypassed. I would only recommend this if you had an EGT gauge, dyno tuning time and/or a wideband. Of course you'd need a way to add more fuel to keep things in check.

Thanks for posting this up WJM.

Nah, I screwed up.

Here is the Field Hyper SFC fuel controller turned on vs it being turned off testing on the dyno. Turned on caused the XT6 to go lean on all geards from 1st to gear the higher the rpm went in that gear. With the SFC turned off, I was testing the affect of fuel pressure being raised/lowered so that is why the two identical lines are red and blue. One setting had a higher fuel pressure than another setting. Fuel was controlled much better with fuel pressure than the SFC.

Now this is making sense to me. I'm thinking the XT6 has the 1-12V (or 1-10V) setup as well. I installed an SAFC on my XT6 a while back and reported to the XT6 folks. The car went WAY lean on the top end. This not only happened with my Apexi SAFC but also with my Simple Field Hyper SFC as well. I'll post a dyno plot with Field Hyper fuel controller turned on and turned off in a moment. The Apexi SAFC unit was printed out and not in a .drf dyno file format so I do not have that to show the results. I was tuning my FWD XT6 at a dragstrip (Cecil County Raceway) that just happened to have a mobile dyno there that night. The results were printed out and those papers are gone. Edit...actually found my old runs I did with the SAFC at the dragstrip. I scanned the pics and posted them up at XT6.net a while back.

Subarutex, Why is it when I ask about the Sensor Calc and Sensor Number setting of the SAFC, you never disclose it?

Patrick, I have one of those gizmos in my garage. Worked great on my Outback Sport when it was turbocharged. Can you post installation instructions once you complete it? I'm interested in seeing how it turns out. I know it is in my basement or garage somewhere.

Has anyone tried this yet?

Interesting! I'll be looking forward to the charts. This is inspiring. can't wait to piggyback off of your findings...my lazy arse.

No, don't make this a MegaSquirt thread. Keep up with the updates on the Emanage.

This does not include the laptop.

I've no luck with Deltacams as far as power goes. Very little gain up high, noticable loss down low (even more so than the gains up high). Top speed will be increased slightly in 1/4 mile. Throttle response will seem somewhat laggy or slower take-off in general.

These threads always turn into a Megasquirt thread. If there is anyone in the Delaware Valley that can install and tune a Megasquirt so I would not have to tinker with it again (unless I change my modifications), then I would go for it. Otherwise, for a low tech person like me, this route would be a complicated and frustrating process. As for the SAFC, those people that have gotten it to run, I have two questions..... 1) What is your Sensor Calc set for?, 2) What is your Sensor Number set for? These where the only problems I had with trying to set an SAFC up for my XT6. It was a complete failure because I could not find the correct settings so I had to remove it. SubaruTex, can you help with an answer to those settings please?

EJ turboing? The EAs seem just fine for that. Boost it up as long as you have enough fuel.

Are you sure about this? Not to go off-topic but an ER27 engine with 2 less cylinders is just about equal to an EA82 N/A engine. 1987 Subaru Horsepower: 97 at 5200 RPM Torque: 103 at 3200 RPM 1989 XT6 Horsepower: 145 @ 5200 rpm Torque: 156 @ 4000 rpm (145/6) * 4 = 97hp (156/6) * 4 = 104lb-ft You didn't say they enlarged the ports to make power though but I figured if they did, they did it for some reason. And, I agree with Will. Both my XT6s and my RX turbo no longer sound like a Subaru anymore. My OBS with the Borla header on the other hand.

From all the reading here, I've been putting 20W50 in my RX turbo. I've switched my XT6s over to this as well.

Another question: Why is the 1st and 2nd run 10hp or so more than the 3rd run? Skrange!

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. ??
