Aprilia Engine
is the output shaft in a funny place on the aprilia RSV?
also There quite down on BHP but way up on torque
is this a good thing or bad?
my new car(Imp) I wont be able to get quite as light as my MK
I was thinking the ZX12r
but the engine already in the imp looks very much like a 4cyl bike engine already
anyone know the dimensions of any good engines

Torque is good if you want lots of acceleration across the whole rev band. Max Power is good if you want lots of acceleration in the top 20% of the
rev band. Of course ideally, you want both.
The aprillia RSV mille has a (slightly) wider spaced gearbox than say and R1 or Blade so you can have lower revs at motorway speeds or a really low
1st gear giving mental acceleration.

Ive got 2 rsvr engines,i have one running in a stand if anyone can tell me how to attach an mpeg video I can post it.
Another good reason for using Aprilia RSV lump is it is already dry sumped as standard,that could save you a small fortune,and the torque
characteristics may be better suited to a car especially when punching out of a corner from lower speeds.

Hi Chris
Yep Id agree with everything thats been said. The Aprilia isnt as easy an install as an R1 in a 7 due to where the sprocket sits vs the tunnel - this
however is of no worries to you as you wont be as constrained by tunnels etc.
I seriously toyed with the idea of using an RSV motor having ridden a couple of them. Like you say they develop bucket loads of torque low down but
are a step down in outright BHP from the inline thou engines. I wouldnt let that put you off they still pull like a train and like Smart51 says
theyre also suited to lower RPM cruising if you get the right diff.
Dry sumped out of the box and that engine note................. awesome.
Given up on the Dodge then mate?
Ive not even finished my 7 yet but have a real liking for a Z cars style mini...........seems to be a recurring theme with kit car builders 
Rgds

Just thought that may help in the torque debate?
I was very close to sourcing a TL1000 motor for my build but went for the R1 for my first attempt...
I'm thinking about a TL powered VortX RT+ next with NOS...

Here's a bit of TL inspiration: -
It has a true 140bhp and 89lb.ft of torque at the back wheel!
It wheelies off the power in 6th!!!! 
Froggy - what's the RSV in?
Spin 'er off Well...

RSV engine
I hope they are more reliable in a car than they are in a bike  . Local bike mechanic dreads them.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Early models were unreliable - from 2001 IIRC they got a complete revamp and became one of the most reliable V twins around

Im going to go and see an imp today see exactly how much room Ive got to play with
I dont get that torque graph
According to most bike data the aprilia makes 100ft of torque
also having ridden one I can say it pulls better in gears than the r1 apart from the ballistic top end...

mine is a tl motor and makes 120hp with 85lb/ft .apart from what it looks like the kitten has some advantages over the mini from a builders point of
view, first its a shed load lighter to start with ,a stock mini is around 750kg where the reliant van is 515kg ,its rear wheel drive with double
wishbone front end and the fuel tank sits under the radiadtor between the chassis rails unlike the mini where it gets baked by the radiator. mine
still sits on 10" wheels which gives it at least a 30kg advantage over a 13" setup . if my sums are right it should be around the 460-475 kg
mark which is pretty much the same as most bec,s but i stay warm and dry

the tl is pretty tough but the gearboxes arent that strong so ive made a chain drive unit just like a go kart using the centre of the bikes rear wheel
to retain the cush drive il post pics once i get the the lobro flanges back for it.
xzr id think about weight more than anything and deffo go for chain drive as if you go for prop and sierra diff you will have the same gaering probs
that other becs have unlike chain drive which you can change to suit the engine .

its a good plan but its a lot of work ,but its an all year round car and mine will be 240bhp/tonne and 300bhp/tonne once the nos kit is
fitted

Which mini weighs 750 kgs? Mine's around 600 kgs. I know that rover managed to add a whole load of weight though.

My ZX10's (same size as zx9 & zzr1100, but a touch smaller than the zx12) give a dimension of approx 24" between the front of the
exhaust headers (foremost point of the engine) & the rear axle centreline. Don't know if that helps at all the ZX10 is dirt cheap (as is the
ZZR) & gives about 137bhp & around 70lbft torque - no need to dry sump with the engines positioned the same way round as the bike, I've
certainly had no problems & pull some pretty high G b4 those big back tyres will let go!

Just to add a point on mini weight the 1959 mini was lightest (around 11cwt I think which would be about 525kg) it then got heavier as the years went
by. I had an autocross mini which weighed less than 400kg, helped by a very thin fibreglass roof, doorskins, rear 3/4 skins, boot & front end, it
also had a very light roll cage made largely from 1&1/2" dia exhaust tube, which I don't think you'd get away with in
competition nowadays!! However it did work cos I stuck it on it's roof & am still hear to tell the tale 22 years later!

I want to put a bike engine in a kitten too but would prefer to change the drive to prop rather than sorting a chain drive due to lack of skills, is
it better to source a new diff (sierra and shorten the axle) or is there a better way? Would love to see more pics froggy if you have them?? Thanks

this is my third modded kitten and my last one had a fiat twin cam engine in but all the weight ruined the cars nippy handling having to use 13"
wheels raised the cars c of g too much making all the extra weight even worse . going with the sierra rear beam will give you the same problems
although using 13" wheels with 175/50/13 do actually fit under the arches the gearing will be on the low side which is why ive gone for a
chain drive to step up the gearing to compensate for the 10" wheels.
z cars have used one of there kits in a saloon but the engine seems a lot further forward than mine

Ok, if that is the case, what is your way of changing the axle to chain drive? e.g - have you changed the whole thing using expensive parts or done it
your own way? And have you kept kitten hubs/brakes? I could look at how my uni formula student team have done it but that would mean waiting until
september
