View Full Version : 19 16v box & willy box
Just browsing some vids and noticed this in a couple of vids...
4th gear
my old williams does a ball hair over 110 at 7k with willy box
my hybrid does a ball hair under 120 at 7k with 19 box
Though the ratios were the same?
same manifolds, same tyres & wheels sizes...

I think they put different ratios in depending on what year they're from tbh. The gearbox I bought my car with had better ratios then the one I put in when I blew it up and they were both the same code and from the same year car.
See ya

my williams is around 105 - 108 at 6.5k mate but with the hot limiter its 110.
mines around 115 at 7100 at mo.was about 10 mph more with cams
same as you martin! just under 120mph in 4th!
we should get the exact codes up for each box.
box, gear, rpm, road speed.

dont forget tho....they all on diff speedos too lol...and wheel/tyre combos
Mine is...
JB3 051, 4th gear, 7000rpm, 195/50/15, 119mph, valver clocks
8)
as above lol But I don't know the code the 19 box
mines around 115 at 7100 at mo.was about 10 mph more with cams
similar, 112mph @ 6500rpm and just shy of 125mph @ 7200rpm. without cams 105mph tops in 4th @ 6500rpm

Cams can't make a difference to the top speed in a gear though. That's dictated by the revs and the gear ratios. :?

Yeh cars can't go any faster that the gearing allows. Only way you can get extra speed is by changing the gearing (or putting taller tyres on) or getting more revs.
There was a guy in Wakefield yesterday claimed his Scooby WRX did 177mph on a standard WRX box. Errrrm no, my mates old one flatted at 130mph just got there fookin quick.
See ya

mine shows about 103 in 4th, std 6500 limiter-std engine, 195-50-15 tyres
is the 19 box a jb5 or jb3?
jb3, but mite have a different code.
i think i saw an rsi with a JB3 043 once....
1st - 35ish,
2nd - 63ish,
3rd - 88ish,
4th - Ill do later,
5th - 140ish - need to verify!
Clio 16v gear box, is it JB3?

thats what i would have thought too.but the loss of cams,with the same rev limit....im 10mph down.
