seanaldo1987 0 Posted May 23, 2009 Report Share Posted May 23, 2009 hi all,looking for some advice with regards to the torque results i got today up at extreme motorsport.running a decat exhaust and pipercross viper with CAF my vr6 golf made 184.6bhp with only 160lbs.ft of torque?????in standard trim the vr6 golfs are 174bhp with 174lbs.ft of torque.is there any reason for this drop off in torque???my mate who was running the same mods made 192bhp with 192lbs.ft of torque.only difference is he had a bmc and i have a pipercrossany advice would be a great helpcheers Link to post Share on other sites
boostjunkie 0 Posted May 23, 2009 Report Share Posted May 23, 2009 it could be alot of things bud,age and milage on the engine, he may just have a stronger engine, I would compression test the engine just to be sure, he also may have a chip in the ecu? or a set of high lift cams? internal engine modifications can also crop up from time to time Link to post Share on other sites
RAPgolfvr6182 2 Posted May 24, 2009 Report Share Posted May 24, 2009 my golf made this bhp same as urs with 158k miles on the clock putting it down to high milage on the engine everything wears away like valve seals and piston seals. so torque will go down. but i did read a while ago that if you increase horsepower expect torque to go down a little bit.

seanaldo1987 0 Posted May 25, 2009 Author Report Share Posted May 25, 2009 Thanks for the replies, all opinions taken onboard.his vr6 was standard internally. it was a couple of months after the rr day he then got schrick 264s fitted.then it got even faster but he never got it back onto the rollers before he sold itmy mate said it might be to do with the fact that the pipercross viper is for a clio 182 and might be restricting it slightly.he said that i should sell the viper, buy a bmc that is for a golf vr6 and get her on the rollers again to see if this makes a difference. if this doesn't make a difference then al just put it down to being a weak engine. once the engine needs a complete overhaul then the transformation can begin :-p Link to post Share on other sites
FishWick 21 Posted May 26, 2009 Report Share Posted May 26, 2009 Could be a dead cam sensor. That usually sees a big drop in torque and power.And yes, lose the filter and get a BMC! Link to post Share on other sites
RAPgolfvr6182 2 Posted May 28, 2009 Report Share Posted May 28, 2009 if it was a dead cam sesnor the car wouldnt run properly surely. my m8s cam sensor went on his serria cosworth and that wouldnt even turn over n start. n when mine went on my vectra it ran like a bag of nails Link to post Share on other sites
FishWick 21 Posted May 29, 2009 Report Share Posted May 29, 2009 It does actually. All that happens is the ECU turns off Sequential injection, runs a bit richer and retards the ignition. Bosch Motronic was pretty sophisticated even in the early 90s.It's subtle and a lot of people don't even notice, until they see their power is down 20% on the dyno. Link to post Share on other sites

FishWick 21 Posted June 1, 2009 Report Share Posted June 1, 2009 Yeah VAG-COM will tell you if the cam sensor is dead, it''ll be something like this - "G40 - Cam position sensor - No signal / short to ground / implausible signal". Link to post Share on other sites
