Posted 28/04/17 12:58 PM Share Posted 28/04/17 12:58 PM Righto guys I am having a lot of tramping issues at the moment that is doing my head in! Stand still starts or even just roll on's now. It did it today at 3000rpm Background of the car: It recently made 625rwhp on a hub dyno. It felt great for a couple weeks after the tune then I took it to the drags and did a couple runs with out an issue. After the 5th run it tramped very hard off the line and I didn't really get off it straight away. Now when ever I start to get on boost it tramps up. I replaced the blade bushes today with white line bushes, I have a twin diff bush hat set up and super pro hybrid front diff bushes. Stock suspension as well. Shocks still feel fine. Any help or ideas would be greatly appreciated. This is doing my head in hahaha. Link to comment Share on other sites More sharing options...

I have polylast bushes and although they are beefy in the middle I'm sure they could still separate at the closed end. Does it still drive straight under load? Are the hat bushes still intact? Is the subframe still lined up? I spose it wouldn't hurt to check every nut and bolt under there with a long bar or torque wrench. Obviously I can't tell you what's wrong but it doesn't hurt to bounce ideas around. Link to comment Share on other sites More sharing options...

Posted 28/04/17 01:19 PM Author Share Posted 28/04/17 01:19 PM Those bushes wouldnt even be more than 5000 kays old. But I will check them. Ill check all the nuts and bolts tomorrow. That's what I am after man, More ideas that get thrown around the closer ill get to finding the issue! Link to comment Share on other sites More sharing options...

It shows the rear end from the front and back. I'd check that there isn't excessive play in the driveline from the front of the tailshaft to the wheels and check the rubber damper at the front of the tail shaft for servicability. There are a few causes for axle tramp but I'm sure you'll get it sorted soon. Link to comment Share on other sites More sharing options...
