Hello gang. I have a question you guys maybe from experience might help me grab the correct ratio.
T-56 Magnums come in two gearsets as you might know.
2.66 1.78 1.30 1.00 .80 .63 2.90
2.97 2.10 1.46 1.00 .74 .50 2.90
The car has about 27" tires. And will make about 450RWHP with a very wide 430WFT/lbs Twin screwed, It will weight about 3850-3900lbs with driver. And its mainly a street car that spends alot of time on the highway and does long trips from time to time. It needs to perform well on the 1/4" but thats not the ultimate goal. Id like to keep the revs around 2k at a cruising speed of 75-85 for mileage. On the nitrous on E/T drags or full slicks and a 50-75HP shot it needs to make a pretty good 60ft. And the occasional corner carving. Oh and redline is about 6500 but can wind up to 69-7000 but does not make much power up there. It peaks about 6200rpms.
With these detail what Magnum would you choose?
Here are some multiplications based on rear end.
