[QUOTE="DSS, post: 11468443, member: 49617"] good kill op, nice kill and keep it up man the weakest link on the USDM STi drivetrain are the axles, even then its beefier than most, the STi 6speed is very strong, i believe the current record right now for the STi 6 speed is 9.2 on the 1/4mile and thats launching on second gear (stock rear end also) and yes he shifted to over drive gear, 6th gear to finish the 1/4mile pass :beer: i cant comment about the newer STi 6speed from the new chassis(08 and up) but i dont see a reason why it would be any weaker than 04-07s trans, based on the spec sheet peak dyno number means nothing, that piece of shit STi prolly has the worse powerband pushing that turbo at that level, he wasted his money and just hurting the car more you heard wrong my friend, these link you sent are among the very few, its def out of the ordinary these STi transmission are very strong, of course your gonna find very few bad apples, and will stand out on these forums, but its proven fact that STi drivetrain are very good (axles is the weakest), its rare find STi that runs 11s,10s, or even 9s, with needing a built transmission, and if you do find a fast STi running fast times with a built transmission is due to, gearing issues, the STi 6 speed gear ratios are is not intended for drag racing heres an example how bad the gear ratio is top speed of every gear at 7200rpm 1st-27mph 2nd-50mph 3rd-72mph 4th-97mph 5th-140mph 6th-gasmileage gear lol they can even blow up bone stock, most of the time is neglect or factory defect, like any other car on the road cheap to expensive main reason why these stock STi engine go "kaboom" its due to the cast piston on a turbo car, and the fuel rail design (debated), which tends to lean out the cylinder #4, a blown ringland is usually the main cause of "kaboom" stock engine STi, the next thing to go at nearly high 4xx whp on a mustang dyno (low to mid 500whp on average dynojet) are the stock rods, which have the same strength as any aftermarket brand of " H-beam " rods, the stock sleeves tends to boom at the high 5xx whp range, not bad for an aluminum 4 cylinder block, shitty piston tho lol your right the 04-07 STi 6speed are proven fact to be very strong, like i said above i dont see a reason why the 08 and up 6speed are any weaker wrx 5speed are piece of shit, lol they are made out of glass, they break at any power level and that sucks for your friend, thats rare to break rods at that power level, specially if has stock piston, that would be the first to go, i can almost garuntee that it was bad tune, detonation ****ed that motor up tuning a complicated ecu and playing around with boost aint exactly easy, there 100s of different subaru tuners, and i can only say 10 of them knows what they are doing, maybe on some other cars its the luck of the draw, but STi 6speed are proven to be very strong, and can take countless abuse, of course theres always gonna be few bad apples and neglect that will break them which prolly less than 5% if you dont mind but which shop is this?
