Valver vs Valver

[clowo16v]

Its a hybrid lol. 1st 2nd and 3rd are a bit lower ratio for acceleration and 4th and 5th are a bit taller for top speed.

See ya

surely you should lose out in 4th and 5th. Valvers struggle in those gears as it is, and if they were taller it would struggle more

[clowo16v]

Yeh but it does 100+ in 3rd so its right on the revs in 4th. Just checked and 3rd is a longer ratio aswell. Pulls to the redline in 5th dead easy. I used a calculator we had in work to work out the best ratios then fitted the ones nearest to that.

See ya

So if you lowered second and raised third, wouldn't that give a bit of a flat spot? And I'm surprised it pulls an even longer fifth

dunno, it's weird, but notice that when you change from 1st to 2nd and 2nd to 3rd your not actually on cam... my diesel box was even worse for this, but 3rd came in at 105mph almost and the flat spot wasn't really bad enough to cost you... on the road the power lost is minimal, but power gained seems ridiculous... for example 4th gear at 4k on my old box, as fast as a valver (i mean identical) in the flat spot and slower than a Williams by 2 car lengths... however, once it pulls on cam it leaves the valver easily and pulls back on the Williams and storms past to 140+mph... very weird indeed... it makes no sense at all to me

Sorry, you've lost me

well if you redline 1st and 2nd (assuming 6'500k) when you change into the next gear it's not on cam (4.5k rpmish) until the higher gears, so in the higher gears making them taller but being in the right revs should actually see an advantage... if you see what I mean... the gearbox I had was 40+mph in 1st and 65ish in 2nd, but change to 3rd and the cars at 3800rpm... but this doesn't really matter as it's in a lower gear so can pull more freely anyway, so the flat spot isn't actually as bad as you think. Best way to see this would be get 2 std cars and increase the rev limiter on one of them, will have a similar effect in that you can hold onto the gear and power for longer. Once your car is on cam it doesn't really matter about the gear ratio (well, within reason), it should still be able to pull. the problem I had on mine was 5th gear... change from 4th and it really didn't have enough power... to even pull itself on cam. I did find a rather big hill to try this and IF you can get 5th gear on cam it would happily just pull all the way round and well off the clock... wouldn't do this tho... the wind noise coming through the vents that I manually closed was scary as hell... as was the light change in direction causing the car to travel a lane or two at a time

Ah, I get ya. Basically a flat spot isn't so critical in the lower gears because it can pull through it.

Still, I'm surprised Clowo's can pull a longer fifth when some people are saying a Valver strugges to pull a standard fifth. Even if the standard box drops off-power in fifth, once its back on, being shorter, it should be pulling easier after that.

exactly Matt, in the lower gears your car being on cam would probably just light the wheels up constantly. Reno got the ratios worked out very cleverly if you ask me.

I honestly cant understand where people get this valvers dont pull in 5th from. Griffidh (Wayne) who I've known for years has a valver with over 100k on the clock and it is fooking awesome, it is the fastest 16v I have ever seen (bar Kirminators in 4th gear...), it was as quick as PK's silver one at lower speeds with 2 of us in it and in 5th will whip round to the limiter in 5th, i've been upto 130 almost in the passenger seat and it has revs left and is still pulling. There honestly must be some not so good valvers out there, as these two are the only ones i have been in to silly speeds and tbh when my car was standard (bar gearbox) there was nothing in it from rolling 1st gear to 70mph. Ive also driven it and it's very very quick.

oh, before i forget, the power in 5th could be actually easier to access if 4th is incredibly long and also worth mentioning is that rpm will almost certainly be out. on my old box 6500rpm on the dials was actually 6980rpm, but now is accurate...

Wish I could have a blast against one of these super quick valvers, it's wierd but mine was the quickest one I tried (and bought!) and will fly upto 120, then for no reason it just stands on its arse and takes an age to go anywhere else...

Also does everyone notice that 3 people in a valver just destroys everything! handling, power!
