Recommendation for RT195 gearing with original Taffy exhaust

I’m after bit of advice from you guys if possible please. I’m building a small block RT195 ( piston ported) and have an original Taffy expansion to go with it plus Italian LI150 gearbox and 46 crown wheel, MEC 58/107 crank. Could anyone recommend what final gear ratio I should be aiming at for a goo...

AF double row hub bearing help required

Just got one of the new AF double row hub bearing to go with my AF clo5e, I notice the bearing has a seal in both ends, do you need to remove the internal one to allow the bearing to be lubricated.
Can’t seem to get through to AF Rayspeed to ask them.

Re: Rapido Race 225 exhaust and gearing recommendations

Thanks all for the info, so I looks like the GP200 (indian) with a 46/19 seems to be what most suggest but can any body tell me how the JL3 Road and the NK Road Race would differ and if the jetting would be around the same.

Re: Gran Turismo GT200 Big block - PHBH 30 Jetting Advice Please

Hi Davidsquaredson, To be honest I found the Sx200 gearbox a bit tall 1st 2nd and 3rd fine and could get upto 50-55mph in 3rd no bother but put it in 4th and power would stagnate it may creep up to 60 but very slowly.

Re: Would reducing squish require change in jetting

Done 650 miles so far and runs great up 3/4 throttle but no more power after that. Thought it was gearbox to tall so changed to an li150 16x46 made a little difference but not much. Then realised I should of not fitted a head gasket with a 58 / 107 crank, this was after I had it dyno’d, so hoping th...

Would reducing squish require change in jetting

Had my Granturismo GT200 set up on dyno and jetted but found it could not make top end power. So checked the squish to find it 1.8mm which I now know is too much and needs to be between 1.2mm to 1.5mm so planning on removing the head gasket. the question is if I remove a 0.5mm head gasket to get the...

What gearbox and crown wheel are you currently using?
What jetting do you have with this set up?
