I want a sequential gearbox!

It makes a Focus ST look like its going backwards and passes a 400bhp evo with ease. With no boost and front wheel drive, who the hell can class that as slow :confused:

No you don't? :confused:

Clutch is strictly for getting it off the line or other very low speed stuff.

My good freind has been driving porsche gt cars for years in series such as British GT, FIA GT3 European Championship, FIA GT Championship and Porsche Mobil 1 Supercup, He and every other driver i have spoken to always use the clutch on downshifts.
 
Sigh...

With traditional manual transmissions, the driver can move from any gear, to any gear, by moving the shifter to the appropriate position. This type of transmission is often referred to as a H-pattern because of the path that the shift lever takes as it selects the various gears. A clutch must be disengaged before the new gear is selected, to disengage the running engine from the transmission, thus stopping all torque transfer. In auto racing, this process is slow and prone to human error; hence the development of the sequential transmission. A true sequential transmission will very often use dog clutch engagement rather than the more usual syncromesh as fitted to a normal H-pattern road car gearbox. Engagement using dogs only requires a very brief interruption of engine torque to complete a shift into any adjacent gear. This allows shifting between gears without the use of the clutch. The clutch would normally be used only for standing starts.

Focus ST let him past, and I think the 106 left the braking quite late to pass the Evo. I can't believe people are doubting it's fast though.

ok then you dont HAVE to use the clutch, but it is recomended if you want the gearbox and clutch to last.

Sorry but your friend is speaking crap... :/

Using the clutch loads on a sequential box is actually just going to do more damage than good. It's just going to overheat because there is no synchro's in there to match the revs... so all that energy is either going to want to spin the clutch or spin the tyres... it will start with the tyres first probably (if you've got a nice fresh carbon ceramic racing compound clutch) but once the clutch is hot enough it will start cooking that instead...

But even then sequential boxes don't last long and need rebuilding every few thousand miles...

So your saying Porsche, Prodrive, Corvette Racing, Ferrari are talking crap are they?

they all tell there drivers to use the clutch

i suggest you get your email client out and start telling these teams with rich racing history's that there doing it all wrong.
 
No I'm saying your source is wrong... as there's no doubt in my mind that those teams didn't say that... or what they said was badly misinterpeted by your source.

Unfortunately for you there have been many links posted that strongly indicate the opposite to what you are suggesting :) Such as the video posted by Clarkey where a top engineer with the VXR Racing team says to NOT use the clutch...

So that's a bunch of people on here, textual and video evidence versus "my friend says"...

It's a quick car - the work he's done to it has really worked well, besides it sounds great and that seq gearbox is fantastic. IMO that's not really a chav car at all - it's genuinely been modified by someone who is keen on mechanics and actually driving the ****ing thing like it's meant to be driven. I see he also seems to do track days - and I bet that car is a monster on a track.

A lot of haters in this thread - from generally people who consider themselves petrolheads yet seem completely clueless to this sort of enjoyment? :dunno:

when i was reading this thread last night i thought i wasnt in OCUK motors as none of the replies made any sense.

Great Post Freefaller....

Aston Martin DBR9 Spec Sheet

Once under way, there’s no need to use the clutch for upshifts because the transmission has a “shift without lift” feature. The driver keeps his foot flat on the gas and pulls the lever back hard; a row of lights on the instrument panel glows orange when it’s time to snatch another gear. When downshifting, it’s not necessary to use the clutch, but doing so is kinder on the car.



Park Place Racing Saleen S7-R Engineer

"We've lowered the redline to 6400 rpm [from 7000]," I was told in a "do-this-don't-do-that" pre-lap briefing. "But don't shift at anything lower than 6000-the car won't like it, and neither will you. Even though it's a race transmission with straight-cut gears, please use the clutch on both up- and downshifts because we don't want to replace any pieces before next week's race at the Glen. We highly recommend heel-and-toeing, as you'll want to crack off downshifts while braking to keep the car settled. If you have any experience with racing slicks, you know they have lots of grip, but this car's engine can easily overpower them.

and i will post up some videos when i dig them out from onboard showing clutch being used on downshifts.


Oh and just for your info, my freinds website http://www.seanedwardsracing.com/

Found one of them http://www.youtube.com/watch?v=CWMuAAd24ao a nice onboard with Rocky at sebring.

That video brought a smile to my face :)

Looks like a very fast car. I can imagine what that Evo driver must have been thinking as the 106 goes past :D

not that im a 106 hater or anything

but pulling out of the corners, the Evo seems to be pulling away slightly. Look at 00:45 into that video. The evo is pulling away

He doesnt get much on him, apart from under breaking, untill halfway down the straight, when all of a sudden, he goes from level pegging with him, to reigning him in

either the evo backed off, or the evo hit some sort of limiter or something

*edit* watching him again, it looks like the 106 might have slipstreamed him.
