Anyone know a good source for mid-engine chassis plans/blueprints? Prefer something with custom suspension. Doesn't matter if its traverse or longitudinal. Thanks.

It's mid-engined, weights under 90kgs, and is fully tested with various engines. Bit expensive though

hi

just tacken MK engineering GT1 for a drive this morning and it is amasing(gave me a huge grin). I dont know if you can get hold of the plans for it if you do I would be intrested in geting a coppy of them. however the kit is much cheaper than any thing else of that tipe I have seen.

ceebmoj loads of questions:

Was it on the track or on a private road?
How was the clutch?
Has the MK got its SVA yet? the website says on its price list "all SVA'd and ready to go" but the pictures havn't changed since Donnington Kit car show last year and that car wouldn't have passed the SVA (it didn't have lights for a start)

How has the chain drive coped? (how long before it needed adjusting)

Its an interesting project, so come on enquiring minds want to know

I wish they'd update their website more often.

hi,

I wish thay would up date the web site more two I presently live in edinburgh and it is a bit of trip but I have been working on the web angle.

the car has changed some what from the pictures on the site. the entire forunt end has been reworked I got hold of some pictures witch I will post on monday if you are intreted.

also the car that was about 2/3 compleat that thay where building ther also had a number of other aditions i.e. hand break, an option of a padle shift system and the normal stick shifting system has been changed to provice a cleaner shift

the car I drove was the old one witch seems to be the deveopment chasy

I know it was naughty but I drove it on the road

the cluch was good I exected it to be much hever than it was I found the car vary easy to drive both a slow speeds and also a with draw droping acceleration.

as for the chain drive it seems to hold up well to the use it has been put to when I terned up the car had obvosly not been used since its last track outing but with only changing the ride hite it was ready for a blast on the street with know ajustment to the drive.

I must be boring you buy know so I will leave it at that but as soon as I can afford it I know I will building one.

Not at all please tell more!! and yes please would love to see the new pictures.

The reason I ask about the chain drive was that when I saw it I wasn't that impressed with the system I felt it look fragile. When I discussed chain drive with another manufactere of a track only version (develoment something, my minds going!!!) they said you had to adjust their chain system between sessions on track. For a road going car this would be impractical. As you say though the Mk1 I saw was a developmental chassis and may have changed.

I'm interested in this kind of car as I have my eye on this, the CorumLM, and the XTR as I think all three look excellent and the sound I will be building one in the future I'm sure.

ok I will scan the new picks on monday with any luck

one of the reasons I was atracted to the GT1 was the cost in compatison to the XTR and CorumLM the price is significantly lower and as much as I would love to build thowes cars ther is know way I could afford to.

I was a bit wored about how manigebel the car would be on the road as a weakend car as oposed to pure track day car.

also like I say the car has had a number of refinments witch I think mack it a much more vible option than it was the inclusion of a e

sory flat laptop batary.

I found the chain drive was a lot beter than expected ther was no agustment to the drive from when the car was on the track and it seamed to hold up to some A road action very well.

I had expected the cluch to be hard to manage but it was very easy to control the car was also alot easer to drive at low speads than I had expected. I found it suprisingly easy to drive around town. all thow the set up was a bit hard for that tipe of driving.

althow I have not no experince of driving this tipe of car i found it very easy and rewarding to drive. My girle frend even gave it a go and she has never driven a bike of any thing other than a ford fester up untill yesterday and she also found it good fun and did not even stall it.

How do the oter cars you menchoned deal with the drive from a bike engin?

AFAIK Most have a drive shaft (ie the engine is turned sideways and a shaft goes to a quaife differential). The Dax and the Westfield BEC version looked very well thought through and I was impressed with both the simplicity and the reliability issue.

The problem I foresee with a chain drive is that a road car does a lot of stop-starting which puts a lot of strain on what is effectively a "heavy bike".

Most heavy bikes I know of have prop shafts (presumably through a gearing system) which is why I'm cautious with it in a car.

Saying that I've seen a road legal single seater that used a chain and I presume thats had not trouble so perhpas my caution is unwarrented.

as you can buy the kit with out chain drive system I would have thort that to some one with a lite experince theas modifications could be made to the GT1.

on a side note thow while I was at the place a nother guy who at first I had not realised was disabled (lost the use of one arm and leg in a bike acident, car ran in to him) was being fited up by the guyes with a spesaly adapted car so I think thay have both the skill and are preped to tack on some falry magor modifications for the customers. this guy was teling me that he had been down evry weak end to discuse the mods and have the car tuned to his needs.

Why dont you design and build your own.
Just see what others have done and take it from there.

Use thick copper wire (about 1mm) or balsawood strips to make up a model mock chassis. You can then bend and twist it, and add subtract peices until you get what you want. With the copper wire its easier because you just solder the wire together. I have used this method on many occasions to test suspension designs, chassis designs, levers jigs etc etc and it works !!!!! I still have some left over from years ago of designs for things. If I new how to post a pikky I would show you what I mean.

Good luck

Very interesting Lawrence. To post pictures you need to have it on a server then either paste the link or use the formatting code {pic}url link eg www.website.piccy.jpg{/pic} Where the {} are really []
Edited to try and get spelling right.
