Twin engined cars
Anybody know what the law would be for twin engined cars over here something like this
here
If it was done would the car have to go through sva again as chassis is "radically altered" and then are you allowed 2 engines or would
one have to be for off road use only and declared as such??
anyone any ideas??

two engines driving separate axles is not allowed under construction and use regs ,as a road car they dont work as having no physical link between the
front and rear axle means each end does whatever it wants to in a corner and unless the engines are pretty powerful all the extra weight dampens any
performance benefit. i did a track day years ago in my lotus carlton and out gunned a twin vr6 golf despite being pretty close power to weight

Might be worth speaking to Tiger. They did a twin engined car. I think the two engines were linked through a diff though.

Tiger's Z100 range were engineered by Z cars

PS They did do a version with one engine per axle but required a *lot* of expensive Motec electriccery to go round corners....

heard that the tiger thing had to have the electrics because it keep understeering due to the power.
Having talked to the fella wit the twin engineed 205 he hasn't had many problems except keeping traction to front wheels.
Just an idea as have all the bits lying including a lsd and coilovers don't really wanna scrap them and nobody's buyin stuff at mo. Tried
ebay but got stung on some stuff because of paypal . So seen that link and thought it would be interesting way to use stuff taking up space.

I know the guy who had the first twin engined mini from Z cars (which incidently was an awesome bit of kit) and it didn't need SVA'ing
just the usual MOT.
It was twin R1 engines through a trick diff with both driving the rear wheels.
On a similar note, slightly illegal over here, but worth a rear as its quite funny have a look at http://www.durocco.com/main.html

I believe that they should have an SVA, but as the donor would usually have a reg already coupled with them looking enough like the original not to
raise eybrows, most dont get SVA'd
As for the C&U regs if you can disconnect the gearlinkage allowing only one engine to be used whilst the other is in netural that tends to satisfy
it. (arguably)
heres a few ive seen:

So yous reckon it should be sva'd but maybe get away with chancing my arm with just an mot with disconnectable hear linkage.
As for the speed bit not really worried theres a roadster on the card's , it was just cos i can and a bit of cheap 4wd fun.
I was emptyin the shed out to make room to start that when the mrs asked what i was going to do with all the peugot stuff when i showed her the
website that was it been told to start that cos she wants a go in it :p
