SlightlyEvil Posted April 13, 2008 Share Posted April 13, 2008 I'm pretty sure I know what's up but before I go spending $ on parts and stuff I thought I'd post the symptoms and see what people think is wrong: - Cruisin' on the highway in 4th and especially 5th gear, at about 2300rpm, floor it, and the rpms rise normally till 3000rpm, then it surges quickly up to about 3700-ish rpm, then drops back to about 3200rpm and continues to accelerate as hard as ever. Engine sounds and feels fine through all this. - Only does this on FULL throttle acceleration in 4th and 5th gear, normal or 3/4 throttle pulls don't do it. - Hard acceleration in 1st - 2nd - 3rd gear is normal, nothing different and no surging at 3200 rpm like in higher gears. Thoughts? Oh, the car is basic stage2 setup - catless up, highflow dp, MR cat back, currently on AP OTS 91 octane map. 105,000kms Link to comment Share on other sites More sharing options...

SlightlyEvil Posted April 13, 2008 Author Share Posted April 13, 2008 No, MT, why? My assumption was clutch was starting to slip since it does it right at the point that the turbo spools fully, and only in gears and from starting RPMs where it's making actually full boost level (pulls starting at around 2000rpm in 4th and 5th). Car shifts and runs fine, just doing that very slight rpm surge at spool. Link to comment Share on other sites More sharing options...
rao Posted April 13, 2008 Share Posted April 13, 2008 It is your clutch. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
RaGe Posted April 13, 2008 Share Posted April 13, 2008 good ole clutch is going. better baby it until you get a replacement. OTM. Sorry I didn't mean to start a war which mainly forum people is all about . Link to comment Share on other sites More sharing options...
SlightlyEvil Posted April 13, 2008 Author Share Posted April 13, 2008 This is what I figured. I'd like to get the 06 WRX FW when I replace the clutch. I've read lots on it but can't find a recommendation of a good aftermarket that would pair well with the 06wrx fw and NOT be as rough to break-in as the spec clutches are. Any recommendations or should I just go with stock clutch? Good idea to replace TOB at time of swap since milage is adding up? Link to comment Share on other sites More sharing options...
Mr. Ed Posted April 19, 2008 Share Posted April 19, 2008 i did a spec stage 1 clutch and wrx fly 20k miles ago...i'm tuned beyond cobb 2 (18psi) have tracked it (1/4 mile) at least 25 trips down the track, and drive it 80miles a day in dallas traffic... and I couldn't be happier oh and that is exactly what happened to my clutch when it started going out. ....not sure how long it could have been babied..but it wasn't worth the car not being there for me on the freeway if I ever needed to punch it.

HansGT Posted April 21, 2008 Share Posted April 21, 2008 ^ spec stage 1 doesn't have a very high torque rating. (most spec LGT set ups require a OEM LGT style fly...which is a dual mass...WRX is a single) ACT HD w/ WRX OEM fly is a good combo. Drives like stock, handles 420ft.lbs. Do a search.

ItalynStylion Posted April 22, 2008 Share Posted April 22, 2008 How much lighter is the WRX OEM fly? And is that the one from the WRX or the STI? Link to comment Share on other sites More sharing options...
HansGT Posted April 23, 2008 Share Posted April 23, 2008 around 4lbs. lighter than LGT oem dual mass fly. Link to comment Share on other sites More sharing options...

Do a search. that's what they say... but mine is holding strong the way it is..... After searching he'll also start to see some are having issues with the act "420lbs" set up wearing out just as quickly as their stock set up did....which raises all sorts of questions Link to comment Share on other sites More sharing options...
HAMMER DOWN Posted April 30, 2008 Share Posted April 30, 2008 They is a little over 10lbs. difference between 5MT's DMF(28.5lbs.) & STi's 6MT's FW (18lbs.) I can't see the WRX's FW weighing any more then the STi's. Mike Mileage:331487 Retired/Sold Link to comment Share on other sites More sharing options...
