ive heard it is illegal to have two working engines in one car whilst driving on the road. is this true?
also, ive been thinking about putting 2 engines in my nova because someone has offerd to make the frame for me and i am currently building a c20let nova so thought i might aswell treat my self to a twin engined one!
what set up do you think would be best? ive got a xe, 2.5 v6 with a few upgrades and a 250ish bhp c20let. i want it to be able to handle though so was thinking more along the lines of 2 2.0 8v's?
ive seen that black corsa with two xe's init but im not sure if that would be abit crazy to drive lol! what engines would you choose? cheers!

i dont no much about the subject other than its deffo a tricky one too pull off,and id deffo be using matching engines,not a v6 and a LET

Ive never understood how you would (even just rear wheel drive) link up the gear linkage and clutch:confused:

f23 gear linkage
same as used on the vx220 just connect them together and use a split hydraulic system for the clutch :thumb:
what black corsa? only twin engined cars ive seen are nova's regal/eds and a lad on mig is building anova too i think.
want to go space framed rear with trailing arms. dont use a **** front subframe in the boot it will never handle
well, a twin engined nova is
1. complex
2. heavy
3. prone to breakdowns
4. honestly, hopelessly impractical
now a mid engined nova with a huge hp motor would be way easier to do, and would be a lot more successful as a car.....
or a high hp front engined fwd nova with decent suspension would be a very good fast car.
but if you want to do it, then go for it
I assume he means Beardys Corsa. Nice choice on rims too BTW :) lol
As for anythign other than a 2.0 8v being crazy to drive, surely that's part of the plan/fun with a twin engined AWD car!
I'm sure it is illegal to run the two engines at the same time on the road also. I'm thinking back to the twin VR6 engined mk2 Golf Rallye from Max Power years ago and the owner mentioned then that he had a removable pin which seperated the gear linkages.

Beardys black corsa is a 3.0v6 but he was building a twin engined white one. ;)

I think he means "boost beast" black wide arches twin exhausts running two tuned LETs

Clutch will be hydrollic, the linkage will be made up with a see saw/bars and such..

Thats the Eds/Regal one...

explain the thought process behind that...

It's got 8 less valves than a C20XE so you can have twice as many.

its only going to be used as a summer weekend car and for track days. im just thinking of ideas at the moment but i do want it to handle really well! and im not botherd how long it takes me to do it either. i like the sound of a mid engined nova... hmmmmmmmmmmmmmmm

a nova with 2 2.0 8vs would handle better than 1 with 2 c20xes is what i thought. thanks :thumb:

You know they weigh almost the same yeah? Block big block.. So they'll be the same, just with the 8vs you'll have less power.

so you have thought "ohh I'll lob two engines in and not even think about how a car handles in the first place, so assume that one cam lighter = better handling"

AFAIK the only twin engine car that does anything other than quarter miles is Jeff Seddon's B16DUB, which is Ian Birch's old Mk3 twin vr6 turbo, and that has had £80grand spent on it's build! I don't see how you think building one with clearly limited knowledge (for example the 2.0 8v comment, and asking on here for advice!) and skill is gonna be a good idea?
I've noticed while I've been on this site that people who build proper projects DON'T ask for advice very often, especially before they even do research/start project.
Hell, I can't cook, so I stay out of the god-damn kitchen!
by the way having two engines running at once is illegal

It is illegal to have 2 engines driving wheels!
AFIK for mot's you have to remove the shafts from one gearbox/engine!
Thats what the twin engine mini man had to do!
by the way having two engines running at once is illegal
go on......
I'm an mot tester and have never personally seen a twin engine car but i've not been made aware of it being illegal?? As for the dicsconnection of the rear driveshafts....that may be an SVA thing??
I thought, and posted that it was illegal also. Don't know or see why though!

its not an easy task to do right, my mate is buildingone, he is just taking his time with it though, but it will be done right when its finished,

jeff seddon who owns big dub used to live around the corner from me, not seen him for a while, but tbh its only recently that his cars been putting half resepctable times in on the 1/4 mile.
think its running 2 2.9 vr6s, where as it used to run 2 2.8s. as my mate supplied the motors. where does £80k come from though? just seems a hell of a lot of money even for something like that tbh!

Can't believe the guff being spoken about a twin engined car being a disaster,
Volkswagen experimented with a twin engined Golf for rallying, and then Kim Mather proved in the 80's that the concept works by producing a twin engined Scirocco that was a rally winning success.
Twin engines means more weight, but also 4wd, independant suspension all round and nigh on 50-50 balance. Surely better than a nose heavy, tractionless, overpowered LET Nova?
but then on a twin engined car you would be better to run a hydraulic clutch so that both equal, **** about with throttle cables, and get both engines revving spot on with eachother. need both engines porducing the same power or one will either be pushing or pulling....and 2 identically built engines will NEVER have the same power. need big **** brakes all round.
alot of money/time for what id think as not alot of gain!

imo as long as they are near enough the same power it'll be fine. the way i see it is if one is producing more power and say pushing the other, then that engine will be under less strain and therefore make its power easier and basically cancel the indifference out. of course even if that isn't the case it still doesnt matter as so what if one is pulling/pushing more than the other, it'll it still going to be doing less work than if it was by itself

Go for it.....the net is full of 'this could happen, you don't wanna do this because of that' posts, just do it and let the results speak for themselves :-)
EDITED with the correct user, whoops, sorry burgo

Thats not quite the same as a guy building it in his spare time!!!

I happen to know Ian Birch personally, who built the car originally. He owned Dubsport and used to work at Awesome GTI (Built a few of their cars back in the day) and he told me at York that if he was charging a customer for labour, plus the parts used to build the car it would cost £80grand. He spent £4k per engine turbocharging them just on parts, so thats £8k straight away. £2k worth of seats, £1500 for the exhaust systems, £800 worth of gauges, new golf Cab headlamps/wings/bumpers/bonnet, custom hoses, fuel lines, fuel tank plus the engines and the shell, new rear subframe, suspension, wheels, tyres. . . And a full inside/out respray. Close to £20k there without a minute of labour or profit!!!!!
letvalva, your mates build looks impressive mate! Nice fabrication. You can tell he knows what he's doing, and I don't see him on here asking for help!

letvalva - good to hear your mates build is still going! Tell him to update the thread!! Also, when he's finished can I borrow the jig? lol
front mount rwd with gearbox in the back ftmfw! lol

The twin engined Scirocco was a home built special, not a factory jobbie. Not just a rally winner but a championship winner too.

Forgive me, but my point was that the guy is asking on here for advice, which means he has no idea where to start!
Fearless on here is building a very special nova and he's doing it in his spare time, I'm not saying that if you have the skills you couldn't do it but some dork asking how he should do it? PLEASE!
Coincidentally, I work for VW and they are quite proud of the rallying heritage. They developed a twin-ingined golf in 1991, and still have the car. I saw it at Milton Keynes head office a couple of years ago!
It's from the rally program that VW got the idea of TSI, super&turbocharging cars.
As i like to say if you need to ask then you normally cant!
letvalva- thats some quality work gone into your mates car, welding looks excellent!

So does that mean you cant drive? Weld? Work on your car?
No one is born able to do anything, and like myself, I can just about weld, so at every oppertunity, im asking for hints and tips!
No one is born able to do anything
Im glad i picked up breathing quite quickly!
And yes exactly, i ask for advice on here about my computer etc as i cant do it myself! But i wouldnt even dream of stripping it down and replacing the motherboard or similar as thats more than i can manage, others will find this easy! Its knowing your limitaions!

well, a twin engined nova is
1. complex
2. heavy
3. prone to breakdowns
4. honestly, hopelessly impractical
now a mid engined nova with a huge hp motor would be way easier to do, and would be a lot more successful as a car.....
or a high hp front engined fwd nova with decent suspension would be a very good fast car.
but if you want to do it, then go for it
i agree i think there abit pointless aswell they crab about all over the road and dont generally seem that fast!! for example the boost beast got smoked on that max power video!!
but each to thier own i supose lol
