Because of Dave's (YUM) high speed run it was realised that the Bara box might have a short 5th gear. I had been told that all the ratio's were standard, this is not the case.

I asked Bara for the tooth count on ALL the gears so that I could work it out myself. Here are the results:

1st 3.6
2nd 2.13
3rd 1.38
4th 1.00
5th 0.863

Alternative 5th gear is .812

 

awsome launch tho

 

Fair play for Martin for checking it all out properly.

 

So your not going to tell us the MPH per 1000rpm with your tyre size then with the old and the new ratio

Steve.

 

Thanks for confirming that Martin, its as I suspected on the day, so frustrating when it was assumed to be standard, Mark looked at me as if it was my problem that Dave was bouncing on the limiter. .

 

mph per 1000rpm is 7% higher on the new ratio .

 

according to my mafs it will do over 200mph, now go try it!

 

Thats teaseing Rod

Steve.

 

are the other gear ratios different or is it just 5th gear.

why are they different?

 

May be a tad short on Power, im a realist I guess 197/198 ish, but Dave will be out to prove me wrong.

 

Does not mean that it will pull it though but I'm sure we will see in due course...

 

Read the previous post Martin, like me you have been there a know it aint easy.

 

we will see, its not like i could actually do any calculations considering i dunno what top speed it did at the limiter with the old gear or what revs it was at

 

Assuming 225/40 x 18 tyres, 8010rpm would equal 203.4mph with the taller fifth .

With the taller fifth, he only needs to pull 7747rpm to do the speed that would make YUM the fastest non-nitros powered Cossie .

 

What is the fastest non nitros,d cossie top speed just now mike?

 

slightly bigger tyres then.

hope you do it Dave.

 

Mike I can now work out what Dave did at Brunters from the info now on this site, wont belong before others do it .

 

Cossie is still Martin, Cossie Powered is some Scottish mate that we cant talk about yet.

 

See Rod's comment and watch out for the Top Speed issue of PF .

 

So YUM did 190mph @ the thrash

 

i worked it out to 196.6, never was any good at maths

 

What was martins speed tho? i know about the scottish cossie mate

 

194.7 was the top speed that my old car made, think that was in June 2003.

 

.my pal has that gearbox........................fuckn noisey bastard it is..............(when the car works).he drives with earplugs in.............

 

That box might be noisy but it did the business for me

 

i always thought 5th was different in mine...now i know why

 

i worked mine out to be 210 at 8200

 

What do you have? 0.80 ? Btw, well done!!

 

yip

 

i'm sure the rolling radius of the tyres increase at that speed

 

they will,but only a very small amount.

 

every little bit helps says the wee wumen that pished in the sea

 

 

don't know miby find out next year

and its got 6 gears

 

cause mine is a race spec engine it has solid lifters and it loves reving
