Martin, would you think its worth me going for the slightly taller 5th gear.
with the engine revving 8k+ on the solid lifters and being on 3.9 ratio's.
im not after top speed runs like some of you guys - i dont have the balls for it, but just curious if the way the rest of my car is if the taller 5th will be a better option?!?

I've found that life I needed.. It's HERE!!
Slightly off the main topic of gear ratios, but relevant to the top speed conversations:

Continental make tyres where are approved to 225mph

I jus tapped mine into the gearbox man calculator & I think I got something wrong 
Got the T5 ratio's off his web sit wit 3.64 final drive & it says I change from 1st to 2nd @ 53 mph ! THAT don't happen !
But it did say I could possibly do over 190mph

Needs to be a well worked out package to get up to the 190s Jb...
Things you need to look at are peak power...needs to be over 7k
Intercooler...charge temps needs to be kept under control
and lastly you need about 550-580 bhp

it's only the 5th gear thats slightly different to the rest of the box looking at the ratios compaired to the standard box
i dont think many people could do 160 even around a track
defo make a differance to top tho as everyone can see
but the normal bara 5th is better suited for track or road
thats my thoughts anyway theres the lower ratio 5th if you need it anyway no extra cost
the way i look at it atleast its a decent box and better than fook all

I know talk is cheap and all that Rod and Im in no way trting to take anyhting away from any of the other guys but mine must be there or very very close with my power.
On a dry day with the right line and no mirrors etc it would do it i think..
what you reckon?

But having said that the shorter 5th is likely to be better for circuit use. Yes it's a 'decent box and it is better than fook all' but what do you mean by that?
I have tried to be honest with my findings and have come clean as soon as I realised that the ratio's were not std, my website has beed updated too.

Yo Martin
i wasn't trying to spin , the box was designed as a fast road/ track day box thats what i meant by better than fook all, as it's a good descent box
I allways thought they were standard ratio aswell and never thought nothing of it untill dave did his top speed run we wouldn't have known
it theres any consolation if a punter wants a box , you can offer the lower 5th
like yourself i wouldn't misslead anyone , fair play
cheers marco

Does that mean while my box is out i can have the taller 5th put in?
When i placed the order for my Box I didnt skimp and go for the £3000 box i went all out and got Martin to get the Best box he possibly could at no expense spared
The reason i went all out was due to the fact i intend on having a Monster Engine that will be used for the Track, 0-60, 0-100, 1/4 mile and Top Speed Runs so where does this leave me?

Can I state that Martin was misled by Bara not him misleading anyone they did not Know what the 5th gear was when Martin asked what standard meant to them, think he did his nut. Closing word, Dave is more than happy with the service & back-up that Martin has provided & I for one expected nothing other than that.
