Guys,
First a little background, I know it`s boring but please stay with me.....
I work for a small UK firm called Competition Transmission Services and we, as the name would sudgest, build transmissions.
Some time ago we felt there was call for a heavy duty gear set for the european `world class` T5 transmission as fitted to the Sierra Cosworth and some TVRs. We asked Quaife Engineering to produce these kits for us and have been selling them world wide for a couple of years now with what could be called fair degree of sucess, so far we have not had one failure, this despite the ever increasing power outputs of the guys running them, the highest we know of so far is over 600bhp and still going strong.
About 18 months back I joined this merry little GT40 band, having bought a 20 year old unstarted KVA, yep, in at the deep end /ubbthreads/images/graemlins/crazy.gif
Now having a background of riding superbikes and wanting a GT40 with too much power than is probably good for you I soon realised that I was going to need a pretty strong transmission and not being in the position to afford a ZF started a campain of harassment on Bernie, the owner of CTS /ubbthreads/images/graemlins/grin.gif.
So, the bit your waiting for, if you`ve not got bored and gone to read about, or watch, drying paint.
I`m glad to say that it paid off, and thought this as good a time as any to anounce that we at CTS will, with Quaife Engineering, be producing a heavy duty gear kit for the Audi 016 transmission /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif
This will be a full gear set including input shaft and will use the standard Audi final drive ratios (3.89 and 4.11). The tooth form will be of a semi helical design and will retain the synchromesh gear engagement and standard cases. Ratios have not been finalised but will give a good usable spread and should top out at 6000prm (using the 3.89 final drive ratio) at around 180mph, should your engine be capable of running over 7000rpm in top, we see no reason why you won`t see a genuine 200mph. These ratios were arrived at using a middle ground between origonal tyre sizes and modern ie: 335/35/17 so should suit most cars. This gear set will also work well on track as a close ratio set by using the standard Audi 4.11 final drive ratio.
We see this gear set as a double solution to the problems of potential weakness in the standard transmission while also rectifying the issues concering usable gear ratios.
Baring disaster we should be able to supply these gear kits sometime later this year at a proposed price of 1340 UK pounds.
This, including the optional Quaife ATB LSDs that are available at 660 UK pounds, should keep the price under two grand for the full gear set and ATB differential.
And this is pretty much what we set out to do, we felt there was a real need for a sensibly priced, good strong transmission for a mid engined car with the right ratios for a supercar (read as GT40, I wasn`t going to let us make something I couldn`t use /ubbthreads/images/graemlins/grin.gif), and should have the option of fitting a torsen type LSD, we know the ATB and like the way it works and it`s strength has never been a question.
So there you have it, I`ll post a list of gear ratios as soon as we have them, pictures when we have the gear set, etc and keep you all up to date as and when things progress.
Cheers,
Stuart.
