It's a 4l80 I use as a 4hp would likely wave a white flag with the power I'm putting through it, The valve pack has been changed but I believe that you can cheat the 4hp by manually shifting it 3 hours ago, CwazyWabbit said: So similar to how motorcrossers attack the whoops? Go at full speed and skip over them without going to the bottom of the hole each time. Pretty much the idea, although I wouldn't recommend just driving at a ditch with it flat to the mat, I might have another video that shows us skipping over the rough terrain 1 Quote Link to comment Share on other sites More sharing options...

Awesome video too! I want to get some shots like that too! So just over a week to go and the exhaust is repaired and back on, just the co drivers seat to adjust and a kick plate fitting.

RedLineMike Posted April 13, 2018 Share Posted April 13, 2018 Rear facing shot is a gopro sticky mount on the atlas pointing backwards, front views are a normal gopro mount held on with a jubilee clip, we did almost cartwheel it whilst testing but unfortunately the lense had some mud on it so it never made the final edit Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted April 13, 2018 Author Share Posted April 13, 2018 Yes, its rather annoying when you get mud or water on the lens! So the sticky mounts do stick then, haha. Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted April 20, 2018 Author Share Posted April 20, 2018 One foot plate added for the co driver! I even managed to use my new press to fold it too! Just a quick fold with some angle and box section! Round 2 is back at Tilmanstone, as Plurenden is waterlogged. I fancy a change of scenery, so I'm going off roading in the 90 at Slindon this weekend! I need to re-seat the gasket on the autobox sump as it's leaking, but apart from that I'm ready for round 3!

I was trying to lift off instead of brake over some of the bumps as it makes some of them bumpier if you do brake. Also on some of the wash board sections, flooring it made it slightly smoother. Yes, I'm in the process of making a little foot plate for Nix! you soon work out that when braking into a washboarded corner it hurts. brake earlier and power through! makes life so much smoother!

Exactly Mikey! as it is very bumpy and that what i tried to do and will do for the rest of this year. I'm really looking forward to the next race!

steve200TDi Posted May 17, 2018 Author Share Posted May 17, 2018 After checking over all the engine and gearbox mounts I found one of the front mounts to be not quite right! One of the bolts had sheared causing the mount to flex and crack on the lower edge (sorry no photos) so I had to remove it, weld it up and drill out the sheared off bolt in the block...fun! I also couldn't get to it, so I had to do some weight saving and chopped some steel out! From this: To this: Then this: It all went well and is now all back together. So I'm all ready to race at the weekend at Bagshot near Guildford. Steve Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted May 17, 2018 Share Posted May 17, 2018 Eeeeh it does my heart good to see another big chunk of pig-iron being cut out of this truck! How thick was that steel??? 1 Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted May 17, 2018 Author Share Posted May 17, 2018 Bowie - they are captive mount, I'll get a picture for you tomorrow. lo-fi - I would say check www.scor4x4.co.uk, but it doesn't say much. Search for Independent fleet services as that car park in the trees is the parc ferme for the race. Racing is from 10am-4pm and scrutineering starts at 8am. Fridge - Thanks! Probably thicker than it ought to be! Steve Quote Link to comment Share on other sites More sharing options...
lo-fi Posted May 17, 2018 Share Posted May 17, 2018 Thanks Steve. Shame its on a Sunday, I'll be down at the Land Rover Rummage, or I'd have popped along to see the beast in action and taken some pics. Quote Link to comment Share on other sites More sharing options...

Just looking at the last picture it looks like the bit of "bodywork" you cut out was thicker steel than the engine mount! If anything the mount looks a little under-built, certainly it looks about 50% below Nige-spec, and for a racer I'd think it actually needs above average beef.

Yes, you're quite right, I did think that the chassis mounts do look a touch on the thin side. I also think the plasma cutting has made the bit chopped out look a little thicker!

It was as much the fact that it's clearly hit & bent the front part of the mount, stuff moves a lot more than you think (especially when racing), rule of thumb is it will move as far as if the rubber part was not there at all... looks like it could do with a little more clearance & either thicker material or some bracing. And/or a less flexible bush. Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted May 22, 2018 Author Share Posted May 22, 2018 A great day was had at the weekend, full report and video soon, but in the mean time check out the awesome photos by Darrel Payne in the events section here: Oh and Fridge you could well be right about the bush flexing as I heard some bangs and clangs at the weekend!

toenden Posted May 22, 2018 Share Posted May 22, 2018 I Think you are right that the engine moves about quite a lot. The 2,5td mounts on mine are not exactly known for their flex but during challenge events the engine drivebelt can chew in a badly placed radiatorhose which is 1,5cm further forward. I think the problem is when enginebreaking going down step edges which might not be that big an issue for your type event though... 😀 /mads Quote Link to comment Share on other sites More sharing options...

As I said, and as Jez taught me, any rubber part (mounts, bushes, bump-stops, etc.) you've got to design as if the rubber isn't there as under the right/wrong condition it *will* flex way further than you thought! 1 Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted May 28, 2018 Author Share Posted May 28, 2018 Bagshot was a great site. It's an old military site, but well worth all the paper work you have to fill out to be able to hire the site! Nice sweeping and flowing turns, with a lot of loose gravel and dust. I did all my laps, but suffered from some misfire towards the afternoon and I think this was down to water as the site is sheltered by trees and there were puddles at various points around the 3.5 mile course. I went to investigate after the race last week and it fired up and rev up fine!, so megasquirt maybe on the cards over the winter! I filmed a lot of my laps so I'll get one uploaded to facebook in due course. I also did some data logging so I had GPS position and speed on my laps, but if you don't have the correct time stamps it's surprisingly difficult to match the film with the data log. So I had to go with one of my early laps, and that still wasn't great. I gave up when it wouldn't play in windows media player, so some more trial error needed before the next race at Copford Sawmill at the start of July.
