Engine ideas anyone?
thats why i was asking about the cars weight dude, i'm not sure what the chassis is but if its a lightweight kitcar type thing then power/weight a high revving bike engine would be good.
hayabusa engines do fetch quite a premium, alternatives could be ZZR1100 or GSXR1100 motors, both of which run carbs and not injection and can be very heavily tuned/turbo'd at suprisingly cheap outlays
check out the gixxerkart videos online for a standard GSXR1100 engine in a go-kart chassis to see my point

One problem i can really forsee is the cost of the dry sump kit and the rear diff for the bike enginechrislandy wrote:The car is a scratch built hillclimb/sprint car I'm designing, it should weigh between 300 and 450kg so I'm not too bothered with huge torque just enough so it doesn't bog down on the start line or coming out of a slow corner but i want it as high reving as I can so I can limit the gearchanges or in the future add bigger cams if I feel the need.

Hayabusa all day long
I would try getting some advice from the guys on this forum
http://www.rgb-racing.org.uk/rgbbb/view ... 010b49d807
Derek and Paul (the guys that came 1st and 2nd last year) are mates of mine and built their own cars from nut and bolt upwards. What they don't know about this stuff is no-ones business.
The other guy that you should talk to on this forum is max1. He and his mate Paul (sneaky pete) have built drag race bikes for about 100 years, so they should be able to chip in too
Good luck

Sorry if i missed it, but what car is it going in and in what series do you want to race? There are so many engine options but those details are vital if you want sensible options.
If your target is under 2L I guess sprinting, and if you have sensible budget restrictions then I would go for any of the deccent transverse modern I4 performance engine, but restrict to an ally block for weight.
Honda B or K series, Toyota 2zz, Tuned Ford (several options), later GM Eco tec etc... All have power, tuning potential and come with decent gearboxes. Motorbike engines are tempting but will cost a lot more to get in a car, need a very light car, and you need to be a preety decent driver to get the best out of them in a car. Car engines are much easier to drive to thier perfromance potential.

I'm swaying towards a rover k series atm as the full engine only weighs 80kg (wet) when stripped of non essentials and you can pick them up for pennies and tune them tried and tested to around 200hp. I've already got a couple of gearboxes floating around here somewhere!
As for the scooby engines, what are the dimensions and weights of the engine and a 2wd gearbox?

How about either a Zetec or Duratec Ford engine? Both can be tuned like the Rover K series, and are plentiful in scrappies, a friend of mine can tune Pinto's to rev to 9k and produce a N/A 210+ BHP. Pinto's are a little heavier, but cheap and unburstable.
A red top Vauxhall can be tuned to about 200Bhp too, and are lighter.
Good luck with this, I often read Dave Walkers contribution to Practical Performance Car magazine, and he's always got lightweights in there with either K series or Zetecs, there must be something in it.

The rover k series is the lightest car engine you will find, but a really expensive one if you you wnt to tune it to 200hp or more. But, if you have the budget it will save you c50kg over a modern, already 200hp engine.
After reading your PM and realising it is a single seater then the best layout is a transaxle and longtitudinal car engine. The only way to get a cheap transaxle now is a FWD audi unit (not TT or A3 as they are transverse), so then it is also cheap to use a VAG engine to match it. If you want to use something different then you are into addaptors or race gearboxes like a Hewlands.

As far as i know the only supercharged Atom engines are the 275 and 300bhp varients. 160bhp, 225bhp and 250bhp Atoms are N/A.tandyboy wrote:i'm sure when Aerial fitted the CTR engine in the atom they also used a supercharger and Honda engines are notoriously expensive to tune
how much does your car weigh as the Hayabusa engine way doesn't really have much torque, and the gearbox will probably be a pig to do
scooby engine would make sense and you can get massive HP and torque by just mapping and changing the turbo at relatively small expense
A Hondata ECU and tuning kit are pretty reasonably priced (
Buggers cancelled my op just a couple of days before it was due. Inconsiderate barstewards!!

People seem to be missing the point on the 2l restriction and turbos.
Its 2.0litres when naturally aspirated - otherwise you have to reduce size by 1.4 as thats the displacement multiplier for turbo'd engines, so all this talk of Sccoby lumps is very moot !! And just for the record an Apexi Power FC would be waaaay less than a grand new and theres plenty second hand for under
