Now put both through a calculator :thumb:

Will give the same answer.

Southie should also check this since he negged me for my oh so inaccurate info which is the staple calculation for every thermodynamics and engine lecturer at my uni as it saves a step halving the radius which reduces the chance of error!

and it really wants to be pi x (r²) as pi x r ² gives an incorrect answer :thumb:

No it doesn't, BIDMAS rules defines the order in which calculations are solved, brackets indices division multiplication addition subtraction, gives the same answer.

The more I sit and think about it, the more tempting it is to forget the 'up to 1400cc' Class regulations, and just bolt in an extreme power XE or LET.

I could almost certainly get the car running one of those engines at 275/300bhp+ respectively, for less money than building another 1.0 turbo unit.

I've spent some time trawling through old 'Cars For Sale' adverts on MIGWEB and the like, and something like the green Corsa LET (J60 OST) that Chris S from Sheffield had would have been an ideal donor car (sadly I believe it's all been sold now).

Great spec., and 450 or so BHP would be rather pleasant in a sub-600kg car.

That'd be insane in that shell lol Will it still be competitive in the higher classes then? And will the lowered/changed engine mounts that it currently has not cause an issue with a larger engine?

J60 used to run ten second passes all day long aswell :) that motor in your shell would be pretty damn crackers lol

Not a chance of it being properly competitive, given the level of competition it would face.

It would need new engine mounts no doubt, but aside from that it would bolt in no problem. I wouldn't want to use an F28, but an F20 dog 'box would be easy to source.

DO IT! I love everything about this car. The 1 litre engine is different but its just not enough. How about a supercharged 1.4?

Well if your going into the "anything goes" category, is there anything els you could/would put in from other cars/bikes for cheep money that would/could keep it competitive?

Why dont you just go for something under 1400cc that way you could keep it in the current class

Because the block has to be visually the same as the original engine for the car.

Where do you draw the line?

You could bolt an engine in the front, one in the back, 4WD, turbo and supercharger on both of them.........it's endless.

And that's the problem, it is literally a bottomless pit of spending if you want to be competitive in any form of motorsport. There is simply no such thing as cheap, someone else is always willing, and able, to spend more than you can.
