Having driven Ice Packs 4/4 and mine back to back, our mogs were neck to neck on acceleration I only gained a nose as I could hold the gears longer.
Ice Packs had the gear set change mine ECU remap on driving Ice Pack it felt flat and gutless but went like stink, mine felt like a bigger engine.
As a road mod I don't think I could live with it on long journeys as the rev's in 5th would be to high at motorway speed.
4.10 ratio 5 gear
2000 RPM 48.4 mph
2500 RPM 60.5 mph
3000 RPM 72.6 mph
3500 RPM 84.7 mph
4000 RPM 96.8 mph
3.73 ratio 5th gear
2500 RPM 66.5 mph
3000 RPM 79.8 mph
3500 RPM 93.1 mph
4000 RPM 106.4 mph
But as a B road Street racer it would be a blast.
The real answer for the road use is torque and BHP.
