Default Stock turbo GP MOTO stage 3 - 220 WHP 260 LB\FT torque

This week Sean from GP MOTO was down from Portland to visit dealers, show off some product, and soak in some of the Southern California car scene. I was his tour guide so to speak, and we had a very fruitful trip. The people that go a chance to check out the Unichip in my car seemed pretty impressed, and receptive to the product. I was even a bit suprised at the results. We installed the Unichip and road tuned it a bit on Monday through Monday evening. Tuesday we headed up to GT Motorsports to try it out on the dyno. Stock WRX's baseline at about 175 on this dyno. Our baseline first run was this 219 Hp and 250 torque. The AFR was pretty close across the board.

After a few pulls the car made roughly the same Hp with a little more torque. Notice that the AFR on pulls 8 and 9 is pretty much smooth across the board. Also notice how much broader the torque curve is than the first pull, and that power comes on sooner, significantly sooner.

On run 13 we got 220 WHP and 260 lb ft of torque. Sean has that print out as it was the highest. I'll post it when I get it back.

This is a subsequent run after we reset the ECU to show just how much learning is done by the ECU. We dropped a ton of power! By reseting the ECU we got 209 WHP and 227 lb ft. Notice the AFR is now rock solid across the board, like sombody used a ruler to draw it in.


The only mods to my car are the GP moto turbo back, Gp moto intake, GP moto 4-2-1 header and the GP moto unichip. Stock turbo and stock intercooler. The boost is set at 1.2 bar. Our best run was the 220 WHp and 260 ft. lb. of torque.

I now have a samco intercooler hose (thanks Jason) because the stocker blew after the car was pulled off the dyno. The header has a leak and will be pulled and welded up fully. All the new GP moto headers are now fully welded. Testing has netted a extra 20 HP from a fully welded header. I plan to go back to the dyno and unhook the unichip and get a good before and after numbers when the header is welded up.

As far as driveability is concerned all I can say is WOW. Full spool has dropped from 3100 RPM to 2750 RPM in forth gear. Keep in mind that I am also peaking at 1.2 bar now vs. the .9 bar I was getting before the unichip. Anyone is welcome to have a ride in my car, it is awesome. The car is as smooth as glass. The guys running the dyno at GT commented on how smooth the car ran.

Admittedly, yes the car could be tuned to the rest of the parts on my car just as well using ecutek or a UTEC. The Unichip has benefits over both these products, and is great for those that desire something more than a reflash. It can drive and control a multitude of accessories, but is simpler to set up and offers more control over accessories than a UTEC. Basically all the tuning capability of a UTEC in a simpler, cheaper package.
I have a complete backup timing map I can go to at the flip of a switch. This is good incase I get a batch of bad gas or if conditions cause a knock. I flip the switch and my timing drops to a preset amount. I can also reset the factory ECU by flipping another switch. This will erase the memory of the knock and allow me to return to my more agressive timing without any problems with the ECU fighting the Unichip.
If you have any questions about my setup or any in general please let me know. The plug and play harness for the STI is 2 weeks away. Let me know if you are interested and I can tell you when it will be available and how to get one.
Regards,
Ashley

I like the torque numbers . Is there any chance that the torque was adjusted where the hp was not? Seems kind of skewed for an EJ20.

The reason the torque and the HP are unbalanced is because I had a header leak at the slip joints that was affecting HP on the top end. Once that is fixed the HP will fall inline around 230-240. The welding of the slip joints has seen Hp gains of around 20 HP.

The reason the torque is so high is because of the header itself. The thing works great. 4-2-1 designs like the GP MOTO typically produce more torque in most applications than a 4-1 design. The car responds very well to the header. Before my engine managment many people that rode in my car though I modified or changed the turbo.

I haven't had time to pull the header and get it welded up, but all the expansion joints will be welded. It has been tested, and there have been no ill effects from completly welding the header. There seems to be enough tubing that the expansion will not make the header crack.

I just noticed, but the hp and torque dont cross at 5252. It seems shifted about 500 rpm to the left.

unfortunately the dyno operator didn't force the HP and Torque to the same scale. If you will notice its about 25 off between the two. So thus the crossing point is around 5252 when looking at the numbers and somewhere else when looking at the plot

Would that make the numbers inaccurate?

Found this----Horsepower = torque x rpm / 5252

Here's an interesting bit of trivia; below 5252 rpm any engine's torque number will always be higher than its horsepower number, and above 5252 rpm any engine's horsepower number will always be higher than its torque number. At 5252 rpm the horsepower and torque numbers will be exactly the same.

No, there is no loss of accuracy by making the scales read different for torque and HP, you just need to make sure that you are reading off the correct scale for that plot. So you could take this data and stuff it into excel and make a scatter plot with HP and Torque on equal scales and thus get a crossover somewhere around 5252.

Is it just my horrible math or does 220whp only equate to a 26% gain. Not that that is shabby. It's pretty much what I would have expected. It's just a tad less than the minimal 60% gain that the site says to expect. . (Let''s not get to far into that again. I just think they need to change the numbers on there page). The torque number is very nice.
