"V" Twin Indy
Have any of you lot out there put a "V" twin bike engine in an Indy.?
A freind of mine would like to put a Suzuki TL1000 or Honda VTR in a light weight sports car and ask me if it would fit in the MK Indy.
What do you guys think ?
Rob
P.S. - My builds coming on well the Pintos rebuilt now and ZX9R carbs are at Bogg Brothers . being rejetted and having a manifold made. I Will post
some pics when they come back.

I have seen a couple of vee twin pheonixes, plus there is a chap on here building a seven with an Aprilia RSV Mille engine in it, plus of course I am
building something a little less conventional:
 
shell on rear corner
a Fiat 126 with 2 Aprilia Mille twins in it!!

The Dutch MK agent build one with a RSV Mille in it, and has it for sale on his website with some pics, so yes a V-twin fits in an Indy.
Check out his site www.haselier.nl go to the menu Sportscars than go to Sportscars verkoop (sales) and you see an Orange Indy click on the picture
and you will see the other pics.
Cheers,
Sebastian.

How do you keep does two engines coupled together?
One wheel at a time or both shaft to one another?
I allways wonder how two engines can pull at a time.
Please feel free to correct my bad English, i'm still learning. Your Dutch is awfull! :-)

Having a VTR thou I wouldn't think it would be that good for a car. Its only about 100 bhp (more soft delivery) but the real big problem is the
reputation for the cam chain tensioners to let go when closing the throttle at high rpm. Apparently snapping the throttle shut is known the cause the
springs to snap in the tensioners.
Look on the vtr100.net (IIRC) forums. Loads of people have had problems. Usually solved by going with manual tensioners or putting a tube in there
that acts as a catcher to stop the tensioner going all the way back in.
Now a gear driven SP1 engine could be interesting (if a little expensive).
A TL Thou engine (or two) could be good. I bet there are a few older ones around as the TL1000S had a reputation for cracking the shock mount or just
plain crashes (As seen on a TL1000S number plate "My other violent slapper is at home"

I have got an rsv mille in my velocity (there are photos in my archive if you want a gander).
The rsv is a 60° v and only just fits, I would think that a vtr or tl (both 90° v’s) would cause huge problems with prop alignment.

Hi Catpuss
I think your right about the VTR SP1 being the better choose, just need to find one at the right price.
I would think that a later TL engine with throttle bodies would do a good job. May be M1 Salvage could help .

Thanks Rob

Check out Russ Bost's Furore. Each engine (2 of them) drive a seperate wheel and it is F***ing fast!

On mine they are (or in a few evening will be! ) physically linked.
This is both mandatory in aurograss racing rules and (sorry Russ!!) very wise in my book!!!
I have a large shaft connecting both engines and acting as a "locked diff", pretty much a spool diff with a drive sprocket on each output
flange if you see what I mean, will photo later.
I am using 630 section chain from each engine, and will be running both engines on DTA S60 Pro ecu's, with mapped injection and ignition, hoping
to make 145-155hp per engine. (later ones are 143hp as std, they also rev to 11,000 which is not bad for a thou twin)
Throttles will be on adjusters on the cables to get equal opening (set up on dial gauge to begin with) clutches are hydraulic as std and just use a
normal girling master cyl with a tee piece in the line. Gear linkages will be cable with adjusters to synch the shifts.

PS the Aprilia Mille engines are MUCH cheaper than the suzuki TL's, more powerful and are also apparently much more robust.
I paid £1000 for 2 x 2004 sub 4000 mile engines with all ancills ( and numbers still on them)

Just a quick question NS Dev, did you manage to get your couplings sorted? I'm probably not going to use my coupling from GB engineering now as
I have managed to do it a different way
Cheers

Hi,
yep, I machined a pair of blanks from EN24T bar and my mate machined the reverse sprocket profile into them in 100 passes each on his pantograph
engraver using a 4x plot on acetate as a copy, fot them on to 3 thou so I was happy enough at that, the error will bed/wear out of them! Paid him with
a spare engine and box I had laying about!
Finished the countershaft too now, will photo and post cos I am quite proud of it!
