For a road legal car but for the purpose of the run it can use slicks but on road legal sized wheels and can have an exhausts system that wouldn't pass on MOT on noise and emissions, etc but otherwise must be a normal road going car not a semi-dragster. What sort of car are we looking at? Skyline? Supra?? How fast are we talking? Anyone care to voice a time/et they think could not be beaten in a road car?

pbee

i think the supra and the skylines are to big and heavy for supersonicly quick quarter miles.

twin hayabusa engined fibreglass kit car. type thing would be my bet on slicks.

not a lotus 7 style something more aerodynamic.

very light and very quick, would need something to help get it off the line though, maybe some kind of programmable launch control.

Pavlo

Is this some post from 5 years ago that got lost in the system till now?

There are plenty of 'road legal' drag cars. They are not actually used on the road day to day, but must be road legal to meet the regs. They can easily do 9s and some may even do 8s. More often than not, big V8 with supercharge and nitrous, RWD with wide tyres, drag slicks for the day.

Road legal covers a multitude of sins.

And yes, it's a stupid question.

Sorry for asking such a stupid question pavlo but I was simply curious to know how fast a road going car you could feasibly build and more critically what route to take. Light with high PWR or big with big power, 4wd or rwd, etc.

There's no way I'd be apologising (even sarcastically) to someone with that attitude

A few years ago this sort of thread would actually start many pages of interesting debate (which I'm sure is what you intended from the nature of the topic) but not now all you get is Pavlo acting like a right know-it-all

Very very sad

Pavlo

thank's SiPie,

I love you too

It's a stupid question.

pbee

something like this with but twin hayabusa turbo engines 400bhp easy.



Single engine version weighs in at just over 500kg so even if a twin was 800kg it would still be very light and supersonicly quick 1/4 mile.

LG John

Nice pbee - what about traction though? Could it really put down great times 8-9s with just rwd and such light weight?

Clearly pavlo has far more evolved thinking when it comes to 1/4m theory so this thread can be for those that don't know so much and would like to theorise on what car would be suitable. I have often wondered about getting a V12 jag ripping all the weight out and strapping some form of forced induction to that big engine

pbee

on slicks with twin engined and launch control i think it would work. Maybe im thinking to small budget minded.

problem is the turbo haybusa engines eat clutches so you probably wouldnt get 3 fast runs out of it, where a skyline would probably do them all day.

wakeboardar

bloody hell 4 new clutches per mile

and i though scoobs were expensive to run

pbee

this is holding 6krpm and releasing the clutch on 2 engines with t5 turbo's, there isnt many uprated clutches available for bike engines. that can withstand the extra weight of the car and the traction of 2 wheels instead of 1.

EvoCarl

A good drag car is a Evo 1-3 Rs.

There light(1170 to 1190kg)
Cheap to mod-get 10 sec engine base built for peanuts
Endless amount of parts available
Transmission is very strong

just have to live with people mistaking it for a scoob

pbee

its got to be 9 secs (maybe even 8's) to be counted which pretty much dismisses evo's and scooby's. (there are exceptions of course).

it has to be light and big power. what about those rs200 replica's fit a 3.0 cosworth lump in it twin turbo. now that would fly.

didnt the rs200 hold the 0-60 record for a really long time ?

Well I thought it was an interesting thread :
I've got an AutoCar Special from Christmas, which ran a load of cars 0-100-0. I think they also gave standing 1/4. It included a road legal drag car (big Chevy engine) which cost c. £100k. I'll fish it out later and let you know.
Cheers
Nick

EvoCarl

theres a few 9 sec Evo 1-3's

Problem is saxo boy said 'not a semi-dragster'

Theres Early Evo's into low 9's etc but obviouly includes wieght saving etc.

theres also a 8 sec Talon(uses the 4g63)

for 8 sec cars your looking at space frame stuff and more than likely lightwieght body panels which falls out of Saxo boys critieria(sp?)

Sounds like Saxo boy is on about a stock wieght or there abouts car which is why I said early Evo model as the starting wieght is low.

Think this is what you need:

It's amzing how some of the old 1960's stuff like the plymouth Barrcudas and Pontiac GTO's keep up with the new stuff

NotoriousREV

I know Kenny said not semi-dragster, but there was a guy down south somewhere that had a road legal '55 Chevy Bel Air complete with a Keith Black 500cu in (about 8.5 litres, IIRC) Funny Car motor, supercharged and running on nitro-methane. De-tuned and only running 1 magneto it produced about 1500bhp. I beleive it ran mid 7's in the 1/4 and was road registered, had tax and MOT, although I highly doubt it was ever used on the road.

M0NEY

There is a high 8 second scoob - by the Rigoli boys.

As fastest road car, as in daily driving as well as the 1/4 mile, i would say skylines. Who was the guy at totb that hit 9.95 in his skyline? He drives that about quite a bit then rags it a few times

If you were just talking about 1/4 mile cars, that will be boring. Rigoli boys hit high 8s and 9s in their cars, but then again its nearly a rebuild after each event. lol

Nup. It still holds it.

The current official world production road car record for 0-60mph was set in 1994 by Graham Hathaway at Millbrook Proving Grounds in a Ford RS200 Evolution at 650hp. Three runs were recorded, the slowest time discarded and the average of the other two taken. 3.06s.

Several cars have "claimed" the record, but none are production cars AND road cars AND have been officially timed. This include:
Dauer 962 LM, 2.7s (based on Porsche 962 Le Mans car - non production).
Tiger Z100, 3.0s (twin-engined, 4WD Se7en clone - non-production).
TVR Speed 12, 3.0s (~850hp - it broke TVRs dyno - 1000kg insano car. Non-one's been mad enough to try it, although someone from the Prodigy bought one. Non-production and Peter Wheeler, boss of TVR, will try and talk you out of buying one if you stump up the cash).
Koeniggsegg CC, 3.0s est - not tested officially.
McLaren F1 LM, 2.9s - non-production.

Hathaway already held the record in another RS200 Evo, but a team from McLaren took it in 3.2s with an F1. Hathaway went back a fortnight later and took it right back again, and it's stood ever since.

IMHO the Caterham R500 must be one of the quickest cars fresh out of the factory with no mods at all on the quater mile.

I remember the 0-100-0 article, the R500 broke the world record for production cars, saw off the Zonda and the McL F1.

CraigH

How can all those cars be "non production" and the RS200 be production? Don't remember a 650hp version being sold through RS dealers

This seems to be an adequate overall car

9.95 @ 160mph, rwd, road tyres. Not too shabby

jaf01uk

What about the car that Tiff Needell used on Top Gear and broke the clutch, think it was a twin engined kit car, Tiger or somethin like that

pbee

it was a twin tiger t100, with 2 yamaha r1 bike engines that tiff broke., my proprosal is a similiar car (more aerodynamic) as opposed to the lotus 7 design. and twin haybausa turbo engines. 2 x 1.3 turbo as opposed to 2 x .9 na.

would definatly need launch control, and as someone also pointed out not exactly mass production. but does it have to be.

it depends what the end point is, does it have to be mass production or just a car built to be used as a road car and a fast 1/4 mile car. that is both road legal and could be used daily ?.

pbee

the rs200 was a production special, it had to be to get homglogation.

still see a few kicking arounf at rally x events and grp a national rallies. quick but very fragile as they are getting on a bit now.

Still does, doen't it?

Anyway, the prob with the Replica is that it's only rear wheel drive, so doesn't get the power down like the old car, and it uses a Renault transaxle which needs a fair bit of work if you want quick launches, although it CAN be done.
They have a motorsport variant on their books, but I'm not sure what spec it is............................

Alcazar

pbee

wow that ultima supposedly will do a 7 @175mph according to the manufacturer.

CraigH

They were guestimates. But only ran a 9.95 @ 160 'cos they couldn't get slicks.

Not bad tho. Did 225 in 5th as well......

LG John

I guess what I'm driving at is what car can you buy, modify, drive to an event (crail, york, etc) then (if you so wish) change the tyres over maybe a few other engine tweaks and then smash out 9s or so 1/4m times - that would be quite a fun weekend play thing

hawkeye

good topic this one saxo boy its all about fun............. not unfortunately for pavlo who no doubt....

STILL HOLDS THE 1/4 mile record for SHED DRIVING!!!!!!!!!!!!!!!!!!!!!!!

dipstick

smb1

Am curious as to what the new RADICAL SR3 Turbo could do?

Anyone know any stats, apart from the fact it now holds the Nurgriging record (spellcheck please!)
