MK2R32 0 Posted January 30, 2005 Report Share Posted January 30, 2005 Anybody know what a standard VR6 gearbox will take, power and torque wise. I've heard of them reliably accepting 350bhp but is this true?The weakest point on the box will certainly be the diff but a quaife ATB should be more than capable.Can anyone shed any light on the subject.Cheers Link to post Share on other sites
Eat this 2 Posted January 30, 2005 Report Share Posted January 30, 2005 i heard 250 lb ft was gettin towards the limit its torque that kills a gearbox not bhp Link to post Share on other sites
MK2R32 0 Posted January 30, 2005 Author Report Share Posted January 30, 2005 I'm running about 275lb/ft or torque at the min on Gas and have had no problems as yet but i was wondering soon it may well be going over 310lb/ft and I was wondering will it survive, bare in mine my Mark2 is a much lighter car than a mark 3. Should be less stress on the box.I've seen plenty of VR cars from the states running turbo's and getting up near 290lb/ft. Link to post Share on other sites
Eat this 2 Posted January 30, 2005 Report Share Posted January 30, 2005 i heard that from mina who had an uprated 6spd box fitted anorak now owns the beast hes probably a better person to talk to or maybe acf Link to post Share on other sites
acf8181 0 Posted January 30, 2005 Report Share Posted January 30, 2005 i've heard of them takin about 350bhp as well....though i'm pretty sure that would be with the diff rivets replaced for bolts, and with a diff fitted. Link to post Share on other sites
VRmonster 1 Posted February 1, 2005 Report Share Posted February 1, 2005 id imagine it will hold around 300+ ft/lb torque but you will soon see the box letting go. the clutch is the main problem. thats where you trouble will be. has it had a new/uprated cluch when the engine went in?

badboyV6 4 Posted February 1, 2005 Report Share Posted February 1, 2005 Are the VR6 boxes completely different to the 2.0 16 valve boxes? Just wondering..... Link to post Share on other sites
acf8181 0 Posted February 1, 2005 Report Share Posted February 1, 2005 the casing is the same but the ratios are all different.both are 02a boxes, but then theres 3 letters to signify what ratios are inside...think vr6 is CCM (but dont quote me on that).'rado vr6 boxes are identical to golf vr6 as well.

MK2R32 0 Posted February 1, 2005 Author Report Share Posted February 1, 2005 My box has been totally rebuit so hopefully it should be ok to take more power. I've an ATB diff installed which has the uprated diff bolts etc. The clutch I'm using is said to be good for 350bhp, have to wait and see on that.These are just some of my concerns when I finally decided to put the charger on. As everyone has told me, it's gonna be abit of a unknown quantity because the VF Engineering R32 kit is designed for a Mark4 which is heavy 4WD car. Should make for an interesting drive when it's finally on and running right. Link to post Share on other sites
