naviathan Posted February 4, 2007 Share Posted February 4, 2007 The Pinks Z had a welded diff and it held up well. Quote Link to comment Share on other sites More sharing options...
rdsk8ter Posted February 4, 2007 Share Posted February 4, 2007 welding a diff will give you the same effects as a spool. you wont be able to corner worth beans it will hop and wear tires out. just my .02 Quote Link to comment Share on other sites More sharing options...
gearheadstik Posted February 4, 2007 Share Posted February 4, 2007 I welded the r200 in the zebra car, It has held up well through a season of pulling the wheels a foot of the ground..prob 800+hp... Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted February 5, 2007 Share Posted February 5, 2007 You need to do a search. There is a lot of info on this in the archives. Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted February 5, 2007 Share Posted February 5, 2007 Typed "welded" into the search function and searched in the "Drivetrain" forum.....http://forums.hybridz.org/search.php?searchid=770666 Quote Link to comment Share on other sites More sharing options...
katman Posted February 5, 2007 Share Posted February 5, 2007 Yup, works great as long as you never have to turn.... Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted February 5, 2007 Share Posted February 5, 2007 Is cost the issue? If not, then buy a Kaaz or Power Brute CLSD or a Quaife torque biasing carrier. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 5, 2007 Share Posted February 5, 2007 Quaife is not a good LSD for drifting as it needs traction to work. Welded will probably work great. Just drop the throttle, turn in, then punch it. Should rotate right around. The car won't want to turn in at autox with a welded diff, that's for sure. I have a friend who tried open, LSD, Detroit Locker (R190) and welded. He ended up using the LSD. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted February 5, 2007 Share Posted February 5, 2007 Quaife bad for drifting... Oops... sorry. I didn't pay close enough attention to the original post. Quote Link to comment Share on other sites More sharing options...

The car won't want to turn in at autox with a welded diff, that's for sure. you wont be able to corner worth beans Dang! I guess the low 1:32.xxxs I ran at WSIR back when the ROD was a BSP car don't count. And those BSP regional and divisional class wins don't count either. I'll send the trophies back. A car with a welded diff can be made to turn but you have to increase rear stiffness, run little to no rear toe, and a lot of front toe out. Basically you make the car loose and use the throttle to drive. Its actually a lot of fun and can be a fast way around a race track. But, as implied above, it isn't THE fastest way.

cpt jack Posted February 6, 2007 Author Share Posted February 6, 2007 do u have to use specific diff oil? Like lsd oil? Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted February 6, 2007 Share Posted February 6, 2007 If the question is for us, we add a product called Hi Tach made by Lucas oil. I have always used this product in all my rear ends with out having any problems. It is an oil stablizer, which actuallys creeps up on all moving parts.

katman Posted February 6, 2007 Share Posted February 6, 2007 "Dang! I guess the low 1:32.xxxs I ran at WSIR back when the ROD was a BSP car don't count. And those BSP regional and divisional class wins don't count either. I'll send the trophies back." We won a lot of races in ITS with a welded diff too. And broke some stub axles. In fact the ultimate demise of the first car was a broken stub axle followed swiftly by tub fatal contact with a wall. Ultimately, like JohnC points out, we were faster with a LSD. edit: Just to clarify- we sold that car and it wasn't under my care when the final shunt occured. Wouldn't want to tarnish my reputation (HA!) as a crew chief. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 6, 2007 Share Posted February 6, 2007 I drove that 510 with the welded diff and it was just like I described. You'd lift, turn, then the ass end would come around and you'd stomp the gas and go around the turn sideways. If you just turned into a corner without really abruptly lifting the throttle virtually nothing happened. It was very drifty but wasn't fast. If you got yours to turn in that's great John, but I still wouldn't recommend a welded diff for autox. Seen a lot of guys who use them for road racing, but the turns aren't as tight and I don't think the understeer issue is as bad at high speeds.
