I am driving this car on the street occasionally and drag racing (1/8 mile) it a couple times a month. I am about to put a Peloquin LSD in and want to change the gear ratio at the same time. I know that the 3.94 is the desired R&P in the heavier MK3 for drag racing. I have the stock R&P 3.389 and can get rubber in 2nd and 3rd when at the drag strip on street tires at 24 psi. Is the 3.94 R&P the best option is a light car? Some people complain of wheel spin city with the 3.94 and 200+ hp. Other people love that gearing with the diesel 5th gear. My goal is to continue to lower my 1/8 mile times, while still drive-able on the street.
Car: 1984 GTI with a VR6 12v OBD2 and 02A with stock R&P 3.389 on 195/50r15 tires
Current Mods: Open Filter Intake, Eurowise SS Header, 2.5 exhaust w/ Magnaflow & no cat, TT Chip, Lightened Flywheel 12 lbs
Future Mods: Eurosport lightened underdrive pulley, Real 2.9 Intake, 1.8T IAT mod, MK4 head gasket, P&P head, 268 TT cams, wrap header, LSD Peloquin, 1.429 for 3rd gear, .75 for 5th
Would the 3.68 R&P be better for a lighter car? or 3.65 or 3.94?
Thank you for opinions.
