JamieP Posted May 13, 2012 Share Posted May 13, 2012 All feels perfect till I get to about 130mph, I can then feel a bit of a vibration, 150 and it's starting to get bad, 170mph and the car feels like its going to tear apart. It's not coming through the steering wheel, feels like its coming from under the car, I thought the undertray may have been loose as I had a similar thing happen on another car, all looks good though. I did wonder if maybe my DSS prop has gone out of balance, but I cant feel anything in the lower gears at all. Any ideas? Quote Link to comment Share on other sites More sharing options...
DARETT Posted May 13, 2012 Share Posted May 13, 2012 Check the prop bud. Had the same symptoms on mine but at a lower speed. It eventually caused the bellhousing to crack off!! It would only happen in 5th as well It felt like the bottom of the car was going to fall apart at the time under acceleration Quote Link to comment Share on other sites More sharing options...

mellonman Posted May 13, 2012 Share Posted May 13, 2012 wheel bearing on its way out maybe Quote Link to comment Share on other sites More sharing options...
David P Posted May 13, 2012 Share Posted May 13, 2012 It does sound prop related, but it might be worth trying a different set of wheels and tyres before you buy a new prop? Quote Link to comment Share on other sites More sharing options...
DARETT Posted May 13, 2012 Share Posted May 13, 2012 If you get a chance have a look first just in case... On mine the crack on the bellhousing made the vibration really bad. Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 13, 2012 Author Share Posted May 13, 2012 I only need the front bit of the prop, got the rest, I will get under it one evening next week and have a look. Quote Link to comment Share on other sites More sharing options...

JamieP Posted May 19, 2012 Author Share Posted May 19, 2012 (edited) Got under it today, prop all looks fine tbh, everything tight and seems to still be straight, new oem complete prop is the best part of £600 new from steve manley. I did notice my gearbox is leaking oil again, i wonder if its low on oil and that could be causing the vibration? Might bite the bullet and buy a new prop, if i borrow one ive only got to change it again or give away a new prop.

SupraStar 3000 Posted May 19, 2012 Share Posted May 19, 2012 Jamie, didnt you say one of your pins dropped out on the caliper resulting in a bit of a scare last week. Could the brake be snatching or binding somehow? Quote Link to comment Share on other sites More sharing options...

SupraStar 3000 Posted May 19, 2012 Share Posted May 19, 2012 Could it have warped or damaged the disc. A few years ago i had terrible vibration at high speeds and it seemed do disappeared once slowed to a lesser speed. A few days before I had painted the caliper red and a small drip of paint had dripped onto the disc. After carefully removing the paint the vibration disappeared.

Hellstrom Posted May 19, 2012 Share Posted May 19, 2012 Would affect all speeds if the disc where tuching. my guess would be the prop is out of balance as it spins on some crazy speeds @ 170mph a wheel bearing would sound alot too if damaged not just vibrate. could be a rear wheel needs rebalanceing aswell. that would not affect the stearing wheel either. or even uneven pressure in the tire could make this happand at thoose speeds.

Hellstrom Posted May 19, 2012 Share Posted May 19, 2012 Cant you just rebalance the one you have? Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 19, 2012 Author Share Posted May 19, 2012 Cant you just rebalance the one you have? If it turns out it is the prop i will send it back to DSS. Quote Link to comment Share on other sites More sharing options...
Hellstrom Posted May 19, 2012 Share Posted May 19, 2012 Okay fair enough i just though it would be nice to still have the uprated one if you wanted to do some 1/4mile again. Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 19, 2012 Author Share Posted May 19, 2012 Id fit it again once repaired if it is that, i dont mind buying the other prop, nice to have a spare anyhow. Just want to get to the bottom of it asap, i dont want to drive it like this. Quote Link to comment Share on other sites More sharing options...
Hellstrom Posted May 19, 2012 Share Posted May 19, 2012 By the way check the rims if you can see a balance weight that might have fallen off Quote Link to comment Share on other sites More sharing options...
