rear end keeps sliding out

not mine but the cars:d

i know that my rear tyres are a bit on the wide side:rolleyes: 305/30 19s but now that i have upgraded my fuelling and to a emanage for the t67. the arse end keeps sliding out as soon as the boost hits around the 0.5/8bar mark.

the alignmnent/tracking is all set to standard and just rechecked my hks hypermax gas pressures which seem fine. no wear on any suspension components/ tyres pressure same on both sides. running cup sport tyres.

 

any suggestions guys. i know that there are a few here running singles and get a great launch without to many problems. so whats the secret.

Just a thought chaps but does some form of progressive or rpm offset boost control help at all with probs like this.

 

Makes me less sure bout goin Single if i'll end up with hard to live with traction issues, 305 width tyres, 0.5-0.8 bar boost and this is in the dry!?????

 

Thought T67 was good moderate size choice for Single, was what i was planning on but don't know if i should consider smaller now:(

Steve it will be fine mate, no more of a handfull than the GT2 you were driving....I would reccomend RLTC for a single, which I never thought I would use, but with 500 odd bhp hammering through the back wheels it would probably make sense to install + I know what your like with your rolling burnouts so most of the time it would be switched off anyway knowing you ;)

67 would be the very limit of what I personally would want to use, I suppose its a personal thing really....other like bigger turbos and all hell breaking lose at 4k rpm, I prefer more low down grunt a much smaller turbo would give. Maybe blag a ride in a 67 and 61 and see which you prefer
