Anti roll bar question
scoobyis2cool - 14/2/04 at 08:35 PM

Hi, I'm trying to set up an anti roll bar at the rear of my car and can't figure out how to attach it to the rear wishbones. Has anyone got any advice and preferably photos of how theyve done it?

being an MK, id speak to martin and see if he has any good advice about it - you never know, he might make rear bones with some sort of mounting point on it.

Do you feel an antiroll bar is necessary? People in the past have implied that strong springs reduce roll anyway. I suppose that the rear springs are softer than the front so maybe they need more assistance. Not being controversial, just wondering!

Sorry I didn't make myself clear - it's not actually for my MK, it's for a racing Westfield that we're currently setting up for next season. We've got the anti-roll bar but we haven't figured out how to attach it to the rear 'bones yet

Thanks for those, but I'm actually fitting it to the rear wishbones


macspeedy - 15/2/04 at 05:56 PM

yeah i know but they are still wishbones?


scoobyis2cool - 15/2/04 at 06:03 PM

Yeah but we think the connection will be different - at the front the bar was attached to the shock mounting points but we won't be able to do that at the back

Found one for you http://www.westicles.net/

it is hidden away in the orange car/ development/ rear arb

hope that helps good luck with your racing!

A common solution is to use a rosejoint SRE bearing attached to one of your existing wishbone bolts.
Cruise the photos on this site for ideas:

this is the cutest antirollbar I have ever seen, totally different but with the same net result, and totally adjustable Rescued attachment RearAntirollbar.jpg

we seem to be going in opposite directions. yesterday I asked the teesside forum if the one on my 1983 corrola differential was worth its weight on a car 2ft. tall. appears easy to mount, but is it necessary?


Terrapin_racing - 18/2/04 at 10:08 AM

Guys, in Allan's HSLC book there is an extract about anti-roll bars. Allan could never tell if his front anti-roll bar made a difference on his Terrapin whereas others swore by them. The rear was always considered a bonus - the weight is at the rear on a Terrapin. It was said that Stirling Moss could tell the difference in the car handling if the bar diameter was increased or decreased by 1/16 of an inch.
It's all trial and error, seat of the pants stuff (unless you have documented data from other users) - one of the reasons for making the outboard top mounts from the suspension links adjustable is to make adjustment / stiffness easy.

I heard it was Graham Hill....!

Terrapin_racing - 19/2/04 at 02:28 PM

I think your right Eddie - I'm getting dyslexic in my old age!

How's that excellent car of yours coming on?
I hope you don't experience too much BTMP like I did a good few years back - Ah - but it was worth it!


eddymcclements - 19/2/04 at 11:24 PM

Car is progressing very slowly at the moment, because another project has been taking a lot of time over the last 4 months - see this link here for an explanation!

Pardon my ignorance, but what's BTMP?

Regards,

Eddy

P.S. Thanks for the book! You have a lot to answer for. Once this Locost is finished I have to build a Terrapin with a longitudinally-mounted engine (like the BDA-powered Gould cars) but using either 1. a 3-litre Alfa V6 or 2. the 3.2-litre V8 out of the front of a Lancia Thema 8.32.

Baby Takes More Priority

saw your latest "project" on your site Eddie.
I have photos like that! Now they want to borrow/drive it - beware!


Terrapin_racing - 20/2/04 at 09:25 AM

PS: If you build the Terrapin it sounds like it will be some monster!

Joking aside, I have exactly the same thoughts. This build is to construct a realistic replica of the original record breaking car - The next well
...have you seen the V8 Hayabusa engine?? Rescued attachment v8haya.jpg

JoelP - 20/2/04 at 09:41 AM

that looks like a MEGA expensive engine!!! How much and where?!?


mackie - 20/2/04 at 10:05 AM

I can't remember the company but istr that it costs about £15k. That gearbox looks new, I doubt the price includes that. It makes about 300bhp and 170lbft of torque from 2l. It's a little bit sexier than a tuned zetec
Now someone just needs to bolt a turbo to it


Terrapin_racing - 20/2/04 at 10:10 AM

Your right, I've seen figures like £18k quoted!
I'm ordering mine when I win the roll-over!


Seriously, Eddie has identified the only real route to do this unless you have cash to burn.

The beauty of the Terrapin race is the chassis and suspension are relatively easy to construct and costs are low.
So you can concentrate on your power plant and drivetrain. If you fit a super motor then MG Vented discs all round is an easy route to stopping on a sixpence.

real motors!

Mackie,

I think you're on about the Cyclone that was in the Quantum Extreme car:
http://www.cyclonepowerltd.co.uk/products.htm

It's 2 R1 blocks bolted together- for £15K It does a whole 300BHP for that too!

Don't know if it's tunable. When a 400BHP 'busa is £8K what the hells the point! If someone's done a twin 'busa tho' that really would be interesting!

James


Terrapin_racing - 20/2/04 at 10:51 AM

Assume it's tuneable also - 800BHP

Is that piccy the Eagle-Weslake Terrapin?


eddymcclements - 10/3/04 at 11:31 AM

It must be an Eagle - that looks like Dan Gurney standing behind the car. Top bloke, great engineer and driver.

I guess we must have a few GPL virtual drivers on this forum?

I have GPL, although not played it in ages.
I wanted some other car skins, but could not get them to work. See my avatar for a clue!
