James Posted June 18, 2011 Share Posted June 18, 2011 It's a fair amount of work and you need a certain amount of savvy with electronics and software— in terms of cost it's about the same as properly PI'ing your car with decent reconditioned parts.

Tim Bancroft Posted June 18, 2011 Share Posted June 18, 2011 For a road car I'd be tempted to stick with a pair of HS6s for now.Get the 2.5 running nicely and then look to fuel inject?I'm firmly in the 2000cc camp for a GT6, but I understand Hugh's thinking. Not been in a 2.5 GT6 so can't compare with mine. But it must be said torque is bloomin' nice! Link to comment Share on other sites More sharing options...
James Posted June 18, 2011 Share Posted June 18, 2011 2.5 GT6- not as good as yours Tim- that's the answer.Harsher when cruising on the motorway and not as fluid to drive on the twisty bits. Link to comment Share on other sites More sharing options...

I do not understand where this comes from?As far as I can see, you can use higher ratio diff's etc with the 2.5, therefore cruising rpm is lower, the higher torque allows better driveability, meaning less gear changes.Having driven both styles of GT6 now, both well modified, I would take the 2.5 any day (well, to be fair Marcus's GT6 is mroe like 2,7l).When driving down to Telford for Stoneleigh, everyone else was having to go up and down the gears constantly (both spitfires and GT6's) whilst we kept up with them in fourth O/D. I might be wrong, but to me that seems like pretty fluid driving to me. Link to comment Share on other sites More sharing options...
James Posted June 20, 2011 Share Posted June 20, 2011 Justify an opinion?I've driven multiple versions of Spit, Gt6 and saloon with both 2 and 2.5— both standard and modified— all variants twin carbs, triple carbs, PI, Webers and EFI.Most of the time I've driven them properly too— not just a pootle about.Nobody has ever accused me of driving slowly either.

Hugh Posted June 20, 2011 Author Share Posted June 20, 2011 Would this Vernier Kit TR6 work with my crank please anyone tell me.Cheers Hugh Link to comment Share on other sites More sharing options...
Richard B Posted June 20, 2011 Share Posted June 20, 2011 Sorry Hugh, which Vernier Kit? :-/The answer is probably. I have not had an experience with them, but as you probably know the duplex setup gives you less options compared to the simplex as you cannot reverse the wheel.Duplex (Tooth and 1/2 Tooth)Simplex (Tooth, 1/4 Tooth, 1/2 Tooth and 3/4 Tooth) Link to comment Share on other sites More sharing options...

Richard B Posted June 20, 2011 Share Posted June 20, 2011 Sorry Hugh, I'm not meaninging to be a smart alec (honest :) )Simplex single width chain (as in Spitfires & GT6's etc)Duplex double width chain (only fitted to 2.5's)I understand that the duplex setup was used due to chain stretch of the PI's. This was caused by the extra load on the chain of turning the PI metering unit against the fuel presure, That said I think it's a bonus for all 6 pots (not sure its justified on 4 pots).I would expect the one you have listed to fit etc, TBH I have never used one, the standard duplex gear seems fine with the 132 bhp cam I use (Standard GT6 MkII early MkIII). I think its for those seeking the last... last... last bit of omph!I nearly bought one at Stoneleigh, but had better things to spend my money on.

Hugh Posted July 1, 2011 Author Share Posted July 1, 2011 The TR6 crank and pistons I bought arrived today and are in great condition for used parts just as the chap I bought them from said they would be. He even left a new duplex crank sprocket on the crank it's nice to deal with someone who is straight up :)Anyway the pistons are standard size as far as I can tell they have Fb69 stamped on the top face of the pistons anyone know what that means.CheersHugh :)Oh he has a full TR6 Pi system which I can also buy is it something worth doing to my car?
