Enough about the engine schmengine.

What is the gearbox (ST75?)?
What are the ratios?
What is the final drive?
What diff are you using?
And whats the tyre size?

Many thanks.

nice...any pics of the engine / airbox set-up?

 

[ScootyMotorsport]

Engine pics on the project thread, so have a look on there.

The gearbox is an ST-75 second generation, ratios are standard cup race car ratios with a 12/55 final drive. Top speed at 7600rpm is 109mph on 15' Kumhos with a o/a diameter of 580mm and 883 revs/mile.

The diff is the sadev plated limited slip diff - nice piece of kit!

How much that set you back if you don't mind me asking

Yeah mainly just the Midlands Championship, but there are a few rallys that I stray north for - The Jim Clark later in the year which is a big closed-public-road stage rally in the Scottish Boarders, the Pendragon stages at Penrith, Neil Howard stages at Blyton near Gainsborough. I'll let people know what events im doing, when and where. If you join the facebook group it will say on there when I've entered them!

Nice one. Already signed up

thankyou please

I love how feisty the car is round the corners, blarring away like a whippit on a spare rib!

the best bit is about half way thru whereby he almost bins it into a wooden lamp post - just awesome.

great post and great work K-tec

 

[Darren S]

Impressive stuff! Good to see an RS being driven in anger too!

I bet there's a fair amount of wedge dropped into developing that car?

D.

Thanks, did you reduce the final drive because you felt the gearing on the standard cup box was a little tall with the original cup 15/56 final drive? How usable would your box be with the 15/56 fd?

He was looking so confidence in driving. Best of luck for 2010

Awesome man

Looks smart, good luck with the new engine and 2010.

The standard final drive in the race cars is 17/55 IIRC. That gave me a top speed of 144mph (eventually) which I would never use on a rally stage. The reason I altered to a 12/55 was because I was planning on making the shell into kit-car spec, wide arched, wide beamed, wide wishbones etc and running it on 17" wheels. The 12/55 would have given me about 125/130mph top speed, ideal for rallying.

I was looking into a 15/56 as this would be so much better with the 15" wheels, but the as the euro is now so strong, the final drive would cost in excess of £1500 before it has even been fitted. :S :dead:

scott your car looks and sounds great. we currently run a 172cup in the scottish tarmack championship . late last year the engine was uprated to a similar spec as yours but on our first event an inlet valve snapped !! any advice on valves and valve springs would be appreciated also what is your rev limiter set at ?
cheers for any help

Is this a european cup car racer originally ot a uk one? If its a UK car, when was the STDSA taken out and fitted with a ST75?

 

[Gavin.]

Hi Willy,

All I can say is talk to Andy at KTec (KTec on here) and he will be sure to sort you out. He knows everything you need to about the F4R - he's your man!

Our limiter is set at 7600 I think. You don't really want to rev them more than that with standard lifters/valves.

Hope this helps!

Cheers,
Scott

It was a show car at Palmer Sport in the UK, built to EU spec though. It was never raced in anger, it sat in the show room in the Palmer Sport base at Bedford Autodrome. Was a mint shell, had done about 1 hours work when I had it!! Engine and box had less than 100 miles on it.
