Hi Guys
The Trans is the usual Renault 21Turbo Box - with all quaife internals - i.e. Single piece input shaft with longer 1st/2nd and a Quaife ATB Diff. Diff Ratio is 3.44 - 5th I think is about 0.76?? (will check at weekend).
Road tyres used for high speed were Pirelli - 26.5" Dia? - P7s..?
For standing quarters and sprints - are 25.0/10.0/15 AVON soft slicks - usually found on the big single seaters - about 23.5" sia i think? They are a bit too soft for continued circuit work and will cook if continually pushed hard - good for a couple of fast laps - even from cold, but then you have to ease off a bit.
The car with Steel 302 4-bolt motor would pull happily to 8K. I've logged and passengered whilst tuning and Roy has pulled off in second, accelerating up to 7990rpm in second before pulling 3rd - and believe me - it sounded great - even with earplugs! We also used to use 7800rpm as a limit at Lhergy Frissel Isle-Of-Man Hill Climb - just awesome..!!
With the alloy 347 we only ever managed about 6000-6200rpm - just kept going flat - something the larger injectors were resolving, however as many know, that motor has sadly been mothballed due to a cracked block. (RIP
) It did however really have buckets of torque which meant we generally didnt change down so much, we'd pull 4th all through Lavant corner at Goodwood on slicks - or 3rd on the Pirelli's. A lap of Goodwood from the Chicane on slicks became 3rd-4th-5th-4th-5th-4th-3rd (6 shifts) and on road Pirelli's, the whole lot could be done in 3rd/4th (4 shifts).
I have some speed in gears data somewhere - in fact I'm sure I posted some years back relating to runs and gearchanges at Brighton Speed Trials - Search and you may find it, if not I may be able to dig it out (actually I'm thinking it might have been a Club Mag article I wrote) - I'll look over the weekend to see if I can find it and post.
I'm busy sorting an i/f to add HIDs to a Mustang at the moment, - it normally drives with daylight running lights (yuk) which I need to disable/ignore as the HIDs go beserk if you try to modulate their supply voltage.... so I'll post again over the weekend after visit to Roy's....
