you do know how to calculate power to weight ratio?
power/weight x1000 = bhp per tonne
so 100 bhp/500kgs = 0.2 x1000 =200 bhp tonne
200 bhp/500 kgs = 0.4 x1000 = 400 bhp tonne

I hope 3 student mech engineers, and 1 electrical engineer should be able to work it out (now you have shown them the way)...! 
Oh, and BEC all the way...!

you would hope so. but to say "bec's have a better power to weight ratio than cec's" is a bold statement. i reckon hicost and
antinuk would gave something to say about that!

building a indy-r myself at the moment, albeit with a busa engine.
i think you might struggle to keep within your budget (mine was £10k, with the engine and its looking more like £12k), my kit came in at £5k (but i
did spec it up and add some extra parts)

Yeah we know about power/weight calcs..
i think ill try and get a spin in one first before i make any decisions. Like i said before ive already for BMW 330i engine sorted but im thinking it
might be a big too big. ill get the kit first then make final decisions about the engine.. ill probably sell the BMW and try and get my hands on a
duratec or zetec something simple and that alot of people are building to start with.
cheers.

If you "get the kit and then decide on the engine" then you may not be surprised when an engine doesn't fit the mounts/cradle
properly.
Do more research and narrow down your choices first.
Then get a run out in one or two.
There are a few KC's in Ireland (can't remember where and I'm sure they won't be your neighbours), but why don't you and
you're friends book a late/saver ticket on the ferry and get over for the KC show at Stoneleigh Park, Coventry this weekend. I know of at least
a handful of people that would take you out...

There you go - a very bold statement!

Yeah steve, i was having a look about and i dont think the 330i fits in the oil sump sits too low under the chassis so unless i cut a bit off and
welded it closed i dont think itll be fitting in and tbh im still a bit nooby with the welder haha. but what ive primarily been looking at is a
duratec as ive heard these fit in quite well and have a good bit of power. i think ill sell the BMW engine and hopefully itll go some of the way to
funding the new one..
Phil, What engine are you running in your hellfire atm.. i was reading your blog last night (Pretty darn sick!  ) and the 0-60 figures are unreal.
3.8 secs. is that a BEC and is it tuned?
Cheers.

all im going to say is, when i started mine, i had a budget of 6K, i have now hit almost 9K and not finished yet!
Its amazing how the credit card mounts up!
But go for it, so much fun, and im sure it will be worth the money once its finished.

I think a fairer statement would be to say that you can achieve a better power to weight ratio with a BEC for a given sum of money.

If you want to know what a BEC sounds like Linky

you probably could get slightly better power to weight for the money but by the time you have a reverse box,power commander,sprocket adaptor they
start to add up price wise. where as a decent zetec could be had for very little money. obviously the bec's are much lighter and that is the
biggest advantage to the handling and braking imo.

BEC all the way.. Current engine is a ZX12R and pretty much standard. There's some videos on our website which might whet your appetite.
