20g 06 WRX

[jbayless10]

I have been working on this car for about a year and a half, and this is where it is as of now. The dyno graph is everything on the car except for the FMIC and gears. A perrin TMIC was replaced with the front mount. All of the work has been done by me, except for the motor build and the gears.

2006 WRX TR

Motor:
RAW1 (formerly AXIS) stage 2 block
1/2 mil over valves
factory heads
FP20G 7cm-internally gated,34mm flapper
DW 750cc injectors
walbro 255
Okada Plasma coils
Perrin TBE no cat
Perrin FMIC

Trans:
STI RA gears
ACT lw flywheel
Exedy Cerametalic Clutch



The car is tuned via open source at 19psi on BP 92 oct. The tune was done on the road and the car was dynoed a few months later. Would like to see over 300 hp/tq with the FMIC and the P&P exhaust manifold going on in a few days.

those #'s seem kinda low for a 20g at 19psi, even with 92 oct. Looks like your car already has a fmic??

[jbayless10]

the pics are new. Yeah I was expecting a bit higher, but oh well. The car kept knocking everytime we tried to add more timing, so we kept it safe.

[howfast?]

theres def more power there. once that gets figured out... think 80 more. why the 7cm and not the 8?

[jbayless10]

I was a effing idiot when I bought the turbo...that is why. I did not do near enough research before making the purchase. I am happy with it though. next will probably be a Grimmspeed EWG setup to draw out some more power.

Td05?

[jbayless10]

no it's a TD06

[ahendrickson]

no offense but those arent great numbers

[jbayless10]

none taken. And I know. There is a lot more left on the table, just gotta get it tweaked.

[ahendrickson]

what are your afr's??? I made 365 whp on a dyno jet with an external wastegate, but I doubt an external made that much of a diffrence.

[jbayless10]

not quite sure. Just got a LC-1 so I will find out soon. I know they are not where they need to be though. runs way rich sometimes.

So you tuned the car without a wideband?!? That is NOT a good idea. From the look of the graph it's possible it was running very rich since a rough looking graph like that usually indicates that the coils/plugs are having a hard time lighting off the air/fuel mixture, but if it was that rich at 19 psi you should have been able to run a fair amount of timing which should have yielded far better number than you are getting. Not to be overly blunt, but I've gotten similar, if not better numbers on stage 1 (reflash only) STi's.

[jbayless10]

no it was tuned on wideband, I just do not know what the afr's are.

[j255c]

either something is very wrong w/ your motor or your tuner has no clue what hes doing. I made over 300wtq @ 3500 w/ an 8cm 20g @ 20psi w/ low 11 a/f's.

[Driveitlikeustoleit]

yea...i mean don't get me wrong good luck with ur setup but i've got a 07 tr with a walbro 255, vf23 turbo, catless tb exhaust, ebay tmic, and intake and i put down 296.5 whp with 326 torque at 18lbs...so you can def get ALOT more outta that big turbo...but regardless gl on ur build...

[06wrxlbart]

Im wondering if he has low compression. Lately I've been looking into building my engine and I heard nothing but horror stories from those off the shelf built blocks. 19psi on a built block is nothing. Go to a real tuner that knows what he's doing.

[jbayless10]

I am not sure what an off the shelf built block is, but it was not preassembled when Ron got it from subaru. My factory heads were used. But yes I need to get a good tune in the car.

[dak125]

Perhaps as a point of reference, my '06 WRX put down 292/352 with just a VF43/STI TMIC/TBE and a tune.

[2007bluewrx]

they should still be higher numbers dude.....I would go to another tuner

[wrxhard]

Am i the only one that didn't miss it? This car was road tuned, then it was dyno'd. It was never dyno tuned from what it sounds like. Which would most likely put up another 20-30 whp or so once optimized. Or am i being optimistic?

You sir are correct. It was never tuned on a dyno, and on the dyno heat soak was killing us due to the lack of a good fan. It will be getting a dyno tune next month with the FMIC, P&P exhaust manifold, and IAG ewg kit. hopefully we can tune it out nice and smooth. would like to see numbers around 340hp/350tq. we will see what happens.

Goodluck with your setup... I wanted a 20G really bad when I first started building mine up but the 2.5 has had such great results with the VF series turbos I went the cheaper route.

[stretchedk7]

I think you will be stoked when you finally get it dyno tuned. Im sure everything is fine, don't worry too much about your less than normal numbers until you get a better tune...!

[jnprn2003]

Go meth, EWG and another tune and you'll see more POWA!

[bajozzy]

Why the STI RA gears and not a 6-speed swap or PPG's or even Mfactory if its a money thing ? Im sure you'll get the bugs worked out if you dont go to the poor house first.
