Cheers for sorting the bits, out, the sprocket is of the N/A variety and not the one I'm after but I could be interested in the gasket kit, I'll call you later to find out what you have.

Here's a pic of a T.T. sprocket.

Have you had a chance to look in your tardis tin?

You need to dumb it down a bit.

You can lead a horse to water................

Laws of physics dictate that these are joined at the hip. Your present (theoretical) top speed is 166mph at 6,800rpm. (5th gear 3k rpm = 73.4mph) (70mph @ 2861rpm) Swapping your 4.083 for a 3.769, would give you a (theoretical) top speed of 180mph at 6.800rpm. (5th gear 3k rpm = 79.5mph) (70mph @ 2641rpm) Alternatively, swapping your 265 35 tyres for 295 40's, would give you a (theoretical) top speed of 179mph at 6,800rpm. (5th gear 3k rpm = 79.2mph) (70mph @ 2651rpm) Either of these ratio's would be a good match for your power level and demonstrates there's more than one way to skin this cat. The same difference can clearly be seen and the tyre swap option results with better traction, better handling and better ride comfort from spending less money doing an easier job, it looks cool too. I have tried it both ways and can assure you that changing the tyres is the better choice. Here's a pic of mine running Hybrid auto transmission, 4.083 A01B diff, 18x10 ET45 wheels 285x40 tyres, (theoretical) top speed of 189mph at 6,800rpm. If I'm ever silly enough to try and get into the 200mph club, I could fit 285 45's and raise the rev limit to 7,000rpm for a (theoretical) top speed of 203mph.

Mapping Suprastick has always been a PITA because the software kept dropping out every few minutes. The problem would appear to be that Suprastick doesn't like serial to USB adaptors. I have now bought an old Windows 98 laptop with a serial port and used this to map Delboy52 Mike's Suprasticked Supra with no issues whatsoever, if anyone needs it, just ask.

The A01A & B are same strength as A02A & B. What are your present wheel and tyre sizes?

Have you checked out the link to Homer's calculator? You could achieve the same by simply increasing the tyre width and or aspect ratio and for a free bonus, get better traction too.

Thank's for the offer, however, it's a G.E. (N/A) set that I would need.

Is this the GTE set you have for sale at £140?

That part no. is for GTE, is this the same set you just offered to me for £220 + P&P?

That sounds more likely to be cause of the sound we haven't heard.

Mmmm, I'll be needing an N/A h.g. too, tempted.

Yes please. Maybe there's a set in the tin next to the tin with the sprocket in it?

Looking for a set of 2J valve stem seals, thinking there must be some unused from a head gasket set, sat on someones shelf somewhere?

That sounds like the kind of place one could be found hiding.

B. Pink.

That's the one.
