So Im tee'd up with Doug next week for my tune, and I was generally wondering how the results were from most Stage II OTS owners experienced after the protune. Ive got a Perrin Short Ram Im installing before hand also that I have laying around as well.
well, the OTS II tune only hits around 9-10 psi from what i see in 1st-2nd, so expect to see that pull way harder and smoother as the boost gets cranked up.
I was told when tuned for, an aftermarket intake is better than a stock box. Im not a fan of cold air intakes, because no matter which one Ive tried on my car, after a downpour or driving through rain Ive looked at my filter and its dripping wet! Even with fog light covers. Im rarely stuck in traffic now, so heat soak isnt much of an issue. At the track I let my car cool down and I rarely run it idle in the staging lanes.
George, stage2 cobb is pretty good man. I think they've done a really good job on it. I used to see 15 boost on 3rd gear by like 2700rpm-3500 or so and it pulled like crazy. Now I was running the VF39 93oct OTS map and it wasn't impressive at all compared to going stage2 from base. Now with SS tune, the difference from the OTS map is just like going from base to stage2. That noticeable difference in performance I mean. What I'm saying is, pro-tune will help, but I don't think it'll be mind blowing over the Stage2 OTS.
I will argue that all day long and I have the logs to prove it. Call Scott Siegel and he will say the same thing. I have a SRI and I am tuned for it as well. It sucks......plain and simple.
I got Protuned last summer. Stage II was an improvement over stock, but you feel an even bigger improvement going from Stage II to a protune! On a good day I'll hit 18PSI in 3rd gear, and it pulls like a champ through every gear. Craig
I logged intake temps of 160 while sitting in the staging lanes with a txs short ram. And this was with 65 degree ambient temps. At those temps it was pulling 2 degrees of timing across the board. Needles to say I am no longer a fan of short ram intakes.
I had a 'shortram' on my RS...noted 160~200 degree F temps in traffic and other slow situations on days with ambiant temps at 80~95. On days cooler than 75 temps still got upto 180, and generally stayed between 130 to 160. With the STOCK intake system as found on the WRX and STi...intake temps were either AT ambiant...but NEVER more than 20 deg. F above ambiant after sitting in traffic. Leave the stock intake on the car, duct, fender box and airbox and all...unless you are going with a rotated mount turbo.
What if I snagged up the cold air extension that goes with the perrin short ram? Could I possibly see higher gains after Protune for it?
The stock air box with a good airfilter will make the same power as a cold air intake. It isn't till you pass the 350hp mark that the stock airbox becomes restrictive. I always recommend keeping the stock airbox untill you go past a stage 2 car.
Most gains seen from intakes are done on cars without tuning. Usually installing an intake will cause the AFR's to lean out which is how they make any power. Once your car is tuned the gains from an intake system are maybe 2-3hp. Now and inlet hose is a different story, usually we see 5-10hp from those and about a 200rpm increase in spool.
Where does the MAF sit? in the fenderwell? I have seen my IAT rise when sitting in traffic even with my CAI. But once I start moving, it starts to drop down real fast.
Milo has the Deadbolt SZ65 which is a stock location turbo. Hmmmmm I'm interested in putting the MAF in the fenderwell. Any issues with wet filters and MAF with it in the fenderwell from driving in the rain? My new foglight ductastic front bumper will let a LOT of air in the fenderwell area (yummy).
Like Delette said, mine's non-rotated and is probably going to stay that way. I'll get meth in the fall and see how it runs. If I'm happy, I'll be done with the car... for the most part
the main thing you will notice difference wise between stage II OTS and protune is the smoothness in acceleration. It won't be as jerky, little bit more torquey and alot more fun. Not to mention a little increase in gas mileage due to the more effecient setup.
I'm not sure why you guys worry about your filters getting wet. On my gc8 I run my filter directly underneath a vent and have driven it that way for the past 3 years. In rain or snow it has never waterlogged or caused me any issues.
I was just about to say the same thing. Unless the filter is totally submerged, you won't suck any water into the intake. I've run a cold air intake for the past 5 years in my last two cars and have never had a problem. I've never driven into any puddles deeper than 4" either, but I've never had any problems with water gettting into my motor.
