Well, got to put an N/A car through its paces on the Dyno. Overall, not bad gains for the mods after tuning. I am not sure what I stock one dynos at yet, but I intend to find out.

Mods:
Injen CAI
Borla UEL headers
High Flow Cat (told it was gutted from rally use)
Magnaflow 2.5" cat-back
Retuned by me



#1 is the retune, #2 is stock. The bumps in torque are from AVLS kicking in (on the logs you can see engine load bump up with torque), I hope they find and add the AVLS map as I believe it will give a better midrange curve. I removed the open loop delays and enrichened the low end to run more timing and leaned out the top end.

Yes thats
155 whp
147 wtq

Awesome. I'll be keeping an eye on this also. Once the bugs are out I may have to give this a shot.

hehe, I wondered how long it would take for someone to get their hands on this and start strapping turbos to the N/A engines. The MAF table has plenty of room, install some injectors and retune and you could have a potent combination.

Looks like the stock MAP sensor will set a CEL around 6 psi of boost though. Although it is easy to turn off the code permanently

Maybe installing a vortech supercharger would be easier....

hmmmmmmmm

I am not sure about that, but first I need to see what a stock 2.5i does on this dyno. It should read the same as PDX. It is hard to compare, since the 2.5i has AVLS and a good intake manifold it definitely has more potential that the earlier models like the one in my 98 RS.

I know a 2001 2.5RS puts down slightly over 120whp on this dyno. Figure a 2.5i could do a little over 130. Add the related mods and a tune and you've got the 150s.

seems plausible.

Yeah baby, wewt =)! He did a great job tuning my car, and man there is a huge noticeable difference at the low end! I'm loving it thus far, but I'll keep an eye on the gas mileage to see what I've lost .

Super nice guy, definitely seemed to know what he was doing, and even detailed out all the newbie questions I threw at him. Thanks again!

Nice work, and quick , looks good and sounds like the driving enjoyment has improved.

Quick question for the tuner, do you feel there is much to gain if you tuned for 93 (91 out west I guess) octane?

^Exactly. Why don't you get crazy and throw a little 89 at it? Or maybe go really wild and throw 91 in.

Cool. Looks like a very solid gain from tuning on an NA setup on 87 octane.

This is a baseline and post SRI install results from decay. Stock is about 132hp/133tq.

Hard to say, just fixing the AFR made the biggest change in torque, the rest was chased with timing. Going to a higher octane would allow a more optimal AFR and you would be able to push timing a bit more too. If the post above mine is correct (I see its a dynojet...) then this car picked up 23 hp at the crank after mods and tune. Thats 196hp, higher octane may push that over 200.

The owner of this car was talking about putting in cams, looking at how the AVLS system increased the torque in steps I can see that a more aggressive cam profile would be beneficial. If we get access to the AVLS system you could make cams with a stock lower profile for great engine idle and driving, and then the AVLS profile for all out power.

It'll be interesting to see what happens now that the tools are in place to tune for mods

Stock 2.0L WRX is over 170whp usually, figure 227 chp. If this one is getting near 200chp it isn't too far off. Some better breathing would help as well, the manifold pressure sensor would read higher and higher vacuum until redline (about 1/2 a psi).

Has anyone logged a stock 2.5i and see what vacuum it pulls at WOT and redline? This one said -.44 psi

I'm interested what higher octane would do to this curve as well...in all seriousness unlike some of our turbo friends.

Hey, I am serious as a heart attack too. I am just wondering why you would buy all those mods and then not pay the +/-.25cents a gallon to get the most out of them? It would be his cheapest mod yet.

hmmm..... cams....... P&P head..... turbo exhaust manifold..... the possibilities are endless now with tunning in our reaches!!


one question though is, who the hell makes cams for the 06-07 2.5i's?

Nobody to my knowledge, could get regrinds maybe? We got Delta Camshaft mere miles from the dyno, maybe I'll call them today and see if it is possible on the AVLS cams.

Look into Delta cams, they'll make cams for anything. And its cheap too because its just regrinding the stock cams.

damn this is pretty sweet. You basically now could just pickup some piping from a wrx and have turbo 2.5 with gobs of lowend

I mean the stock wrx turbo components you can get for practically free!
