0-100 in under 10 - whats needed?
I've been having a good discussion at work about whats needed for a sub 10 second 0-100. All this was started when people asked 'how fast
is my car going to be'. I said I haven't got a clue and that what ever car it is is limited by traction more than anything, I guess
launch/traction control/rubber will help here.
What sort of engine/weight/configuration combo is needed? or what cars on here will do it? A Middy must be good due to the extra weight over the
driven wheels I guess?

Pretty sure mine could but obviously its never been over 70!About 200horses and fairly light 7 should be near without traction controll etc in my
opinion!

A high cliff
Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

I'm not sure I do.... the brick wall areodynamics we have might have some effect getting on for those speeds, eating a few HP.
I can remember in one mag years ago where a car was quicker with 2 people in due to the extra weight over the rear.

Mine would do it comfortably. 291bhp, 520kg.
A shade under 3 sec to 60mph and another 4sec to 100mph so 7secs
Otherwise have a look here:
http://www.strikeengine.com/performance-car-specs-0-60-0-100-power-weight-top-speed.html
and
http://www.torquestats.com/index.php?pid=mph100
Loads are listed.

Did you test it properly 0-100? Its got me thinking of what mine might be like too.

I don't think that site is much use because it doesn't take into account the high torque of your engine - your car is going to accelerate
hard from 2000 - 8000 rpm, not just in a narrow 2-3000 rpm powerband.
I think the only real answer is to buy some sticky tyres, take it to a track and find out. But to get your best possible time, you're going to
have to be willing to abuse your clutch, which makes it all a bit academic.

that letstourquebhp site is total mince. doesn't take into account any aerodynamics of the car, and especially GEARING,
for a 700kg car, 200bhp, it reckons it'll do it in 10.75 sec.
great, but supposing i have a crap gearbox with a 5th gear with a 1.5 ratio, and a 3.44 diff. i can only manage 92mph accourding to gearcalc.
total nonsense

R4 will do it pretty comfortably in 10, 170hp/~350kg (just under 7 to 100) you don't need mega power just loose that weight!

Cool. What did you use to log it? Thats a quick car!!!
Dave, its a new clutch(well 2k old) so it should take some abuse. The racelogic should do the rest, you'll know well before me

Well if you lot put the engine at the right end you'd find it much easier!
Sure the new Furore will do it easily tho' haven't found any dry roads to check on as yet!, 190BHP 113 ft/lbs (times the torque multiplier
b4 the gearbox for a fair comparison!) ZZR1400 in 560Kgs
James (Cloudy) surely your car can't really be sub 350kgs??? Where have you had that weight checked (I've had variations of over 250kgs
from IVA stations for very similar cars - gives you great confidence in their equipment & measuring techniques!!!)
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

I'm pretty sure it's within 25kg of that - I used the 4 bathroom scale method - hence the ~ !
The fact I can pick the front of the car up and it's logged performance does seem to verify those measurements however

Is it a GPS logged figure though? or just wheel speed on a ETB dash?

Both, I calibrated my ETB by GPS comparison - but I do have a 10Hz gps device

My datalogged times are wheel speed timed without wheel spin.

Franky, with the m3 power you'll breeze it, My old s2000 powered Mk indy did 110mph in 12.1 and went through the 1/8 trap at 92mph in 7.7
seconds, so i'd say 230bhp in a cec is enough to do 100mph in 10 seconds
My current car takes approx 500bhp to do it, but then it does weigh just shy of 2 ton
