Looking at buying a kit car aug / sept westfield or sylva.
what are the pros and cons re bike engine cars?
I like the idea of bike engine as I was a motorcycle instructor,but how well do they adapt in a car!
what should be avoided / what is the ideal setup ?
how does the bec compare with say a 1800zetec or cvh/pinto?
cheers Russell
Morning Russell.
I suggest you stick the kettle on and make yourself a mug of coffee... then search the forum using "CEC v BEC" or similar terms!
Loads of reading to be found as this debate comes up regularly!
Hi bec great toy tear about trackday race etc pain in the arse long journey crusing etc Cec great long jouney more use if you want to do more
miles
Zetec cheap good spares etc short on power duratec more expensive to make fit but can tune for real power way faster than any bec apart from busa
turbo
Lightweight car - Lightweight engine
cheers,
kettle on lets see what we can find!!!!!
thinking more for road use,sounds like bec a bit of a pain on the road (town driving) !!!
shame quite fancied a modern 4 wheeled bike.....

Not trying to put you off bec we have both just gearing and torque issuses etc sequential box is great fun you need to have a go in both before you decide someone on here will offer i am sure
Properly set up and geared there should be no issues with driving a BEC on the road everyday
Stick to a Ford/Vauxhall/Car-Engined car. Car engines were designed for cars, you're looking at a car. Lots of torque, from a Chevy V8 (usually
found in a Dax), to a smaller lump (normally found in Westfields, etc.). The old Pinto lump still represents the pinnacle of kit car powerplants. The
engines themselves often come with nice bodywork around them as standard, with cup holders, heated seats and all sorts of essential stuff.
Bike engines produce very little torque, are unreliable. Nothing smaller than a Hayabusa is worth considering. There's no reverse as standard,
just all far too much hassle really. I wouldn't use one.

BEC all the way for me, ive had 3 now builing my fourth. Done thousands of miles, track and road.
get intouch with Bob from spain, bobinspain is his user name, he might be close by to you, he has a BEC
There is only one thing that would swing me to a BEC - if I wanted a sequential change without spending £ks on a quaife or similar car gearbox.
All the other 'fors and againsts' can be offset and balanced out by various vaild arguments.

or the comment,

Pinto, Hyabusa etc are all gutless rubbish!
Stick a V8 in it
CEC

Why is it a few havent spotted the intended humor in this post.... lol
I mean just look at the 'building' section of his username!
I liked this bit ;D
"The engines themselves often come with nice bodywork around them as standard, with cup holders, heated seats and all sorts of essential
stuff"
Copied & pasted from previous posts. As it is a definitive guide though, maybe we should get it made into a Sticky............
Lets deal with bike engines first.....
Pro’s
1 - Performance - Standard bike engine and gearbox = more bhp/kg than your standard car engine and gearbox (in most cases) which makes for awesome
acceleration
2 - 13,000 rpm Soundtrack - Superb noise
3 - Advanced Technology. How many normally aspirated 1,200cc car engines do you know that produce 180 Bhp?
4 - Lightweight & compact = Easier to handle and no need for special lifting gear
5 - Mechanically, they are easier to maintain. Clutch changes etc
6 - Cheaper Vehicle Excise Duty (Tax, to you and me)
7 - Far cheaper import tax (In case you ever consider emigrating to somewhere like……… Cyprus)
8 - Smaller & easier to clean – therefore more environmentally friendly
Con’s
1 - Standard bike engine is likely to be more expensive than your standard car engine
I haven't included 'no reverse gear' because that can be both a 'Pro' and a 'Con'
Now onto car engines (apart from Honda S2000, which technically in my mind is made by Honda, so also a bike engine)
Pro's
Nope, can't think of any. I'm really struggling on this one..............
Con's
1 - Too heavy
2 - Too slow
3 - Too oily
4 - Unreliable
5 - It's a car engine
So there you have it...... A definitive guide to the pro's and con's of BEC & CEC.......
Now onto the 'red herring' that the CEC boys like to throw in regarding torque;
It is quite difficult to compare torque like for like in BEC v CEC. There is a common misconception that bike engines lack torque due to figures being
quoted at the crank. But what you need to consider, is that bike engines have a torque multiplier in the form of a primary reduction gear. So in the
real world, BEC torque actually isn't as low as it would first appear............

Lets just unbias this a little and stick to (mainly) facts. (IMO!)
BECS
Pro’s
1 - Weight - light weight means more BHP/Tonne
2 - Lightweight & compact = Easier to handle and no need for special lifting gear
3 - Built on Sequential Gearbox.
4 - Cheaper Vehicle Excise Duty (Road tac) based on most bike engines being under 1549cc. (£130.00 where as anything over 1549cc is £215)
5 - Smaller /more compact - easier instalation into small engine bays (ie midi style car)
Con’s
1 - Bike engines are likely to be more expensive than a car engine
2- Gearboxes can be considered 'rough' or 'harsh' for slower driving.
3 - No reverse - New required for IVA, so you will need an expensive reverse gearbox, or a custom 'starter motor' based reverse set up.
4 - Lack of torque, despite any arguments its not the case, BECs do generlly have a lot less torque than CECs, and as BECs are intended to be used on
sub 200kg bikes, sticking them im a 500kg kit can lead to needing to be in the right gear at the right time, everytime.
5 - (linked with above), Gear ratios can be harder to get 'right'.
6 - If aiming for a 'New registration' then using a 'reconditioned to as new ' bike engine/gearbox combo counts as 2 components,
meaning you will need to use (or atleast provide evidence) that the engine is 'new'
Neutral These can be used as pros or cons depending on your preference
Noise - Bike engines sound great, but are also loud!
CECS
Pro's
1. Cheaper and easier to come by.
2. Higher levels of torque to suit the weight of a kit car.
3. Engines are seperate to gearboxes meaning an easier 'new registration' should that be your preference
4. 1 Donor build (ie 1 donor car, and kit car chassis/parts and you have all you need)
Con's
1 - Heavier than BECs
[Edited on 28/2/12 by loggyboy]
excellent info looks like a BEC for me or is it a CEC need to drive one when back in the uk
electric reverse is it any good ?
cheers chaps
Russell
[Edited on 27/2/12 by ross05]
If you're intending to do trackdays, a big "con" with a BEC is noise. Circuits are getting tighter on noise limits all the time.
Anyway, here's a vid of my slow, heavy, unreliable... oily, granted! Pinto chasing a BEC round Teesside kart track. (With a queasy passenger
on board)
BEC v Anchor
Forgot to add that bike engined cars are hopeless in the wet, that no torque and all-or-nothing thing again, hopeless.
http://www.youtube.com/watch?v=PoEH1kn3HqE
Mine is pretty useless in the wet, but I put that down to 1 wheel drive at the back
I have a busa powered Indy, and it really is a matter of taste, the car is stunning but only if you drive it like a banzai mental asylum ninja
escapee. Then the seq shift works beautifully and it all just comes alive and eats up a good driving road. In town or stuck behind a convoy of day
dreaming holiday makers it is more awkward though, and less refined to drive slowly.
If you just want to go out and use the car in a legalish and slow way including occasional motorway trips, then the CEC is better. As the longest
tunnel in the UK is only just down the road BEC was the only choice for me, in the tunnel it is glorious.
By the way - any BEC torque doubters are welcome to come out in my car. It pulls strong from low revs but if you're driving the car properly
you're always in the right gear anyway!
I race a BEC and have a CEC Seven on the road... Personally if its for track then BEC, if its for short road journeys, maybe BEC otherwise its CEC for a road toy. However the 3rd car is a race CEC........

Just go for a spin in both and then decide which bike engine to fit

Hi, bike engine every time. Iv got a zzr1100 in 350kg's. Parts are pretty cheap. Easy to work on. Sequential box, but no revrese on mine. The screaming revs! If Gordon Murray says power to weight is everything, who am I to argue. You want absolute minimum of a 900 or you'll have no torque.
You need one of these...

This is quite a simple question to answer.

Hi been looking on tinternet cannot find Holden bike engine
Russell,
Jump on the trans-Med express and get yourself up to Las Fuentes and I'll take you out in my 'toy'. I echo everything that
95% of the posters say on here, (Custardpants (Luke) in particular, because he has the same car).
Motorcycle_mayhem's comments about cup-holders and heated seats are very important issues out here in Spain and should be taken seriously, (like
driving in rain!------- What's that?)
cheers Bob,
how are you getting on with bike power,thought I would give you time to adjust!! no cup holder could be a problem
speak soon
cheers Russ

Well if we're sticking to "facts"...
Where do you get point six from?
My R1 engine/'box counted as one component and I got a new reg. There's plenty more out there. I asked DVLA in advance, stating that it was a single unit and their answer was "Can you use one bit without the other? If not then we'll count it as one". Think about it. If you use a front wheel drive engine and box in a middy, would that be three items? Engine , gearbox and diff'?

well I am sold looks like bike power for me,the vids are great.
thankyou all for your comments
aug / sept we will be looking for BIKE POWER

Was your engine gearbox a recon or new?
Not sure about your other points as none were mentioned in my post, but were in the 'comedy' post prior to mine.

Yes wasn't refering to your post with the other bits and despite the "comedy" nature of the post, they are point's that get trotted out regularly.
I did the LeMans Classic with a car engined Fury owner as passenger and his verdict on suitability of touring a BEC... Just the same as his!
I had a cec first off then when I decided to build my own I went for the bec for a change, love it
Oh and dvla can be hopeless.
I went for an age related plate, all receipts etc, agreed I would get age related (89)
But I had a private reg to go on as the first reg, that obviously confused them and I ended up with it being a 2011 new plate if I want to transfer it
back again !
Not that i'm complaing mind, the local office was very helpfull and a pleasure to deal with.
