Final Drive is different than gear ratios! Taking an example of a 21-speed bicycle, gear ratios would be the 7 gears in the rear, while the final drive would be the 3 big gears up front! Using different front gears doesn't affect the rear gear ratios in any way :) Shortening the final drive doesn't change the amount of whp the engine makes, but it does increase the amount of torque it produces! Shorter FD = Less Effort = More Torque :) Hope that helps!
Unfortunately I never got to take it out for a 1/4mile run..The car is pretty light (2,500lbs with me inside), and with the short gearing, I was predicting somewhere between low to mid 14s! And yes these F20Bs just LOVE to rev to 9000RPM!
yeah, you are agreeing with me. the guy i responded to doesnt understand what you just told me... so tell his this post. he thinks he can get more tq out of his motor by shortening the final ratios....
What would you guess you're car runs on the 1/4 mile?I say easily low 14s.What are you revving you're motor to?I have pro 2 cams peaked at 8k rpms and I'm we had the rev limit set at 9k on my f20b.
if that is true, it has nothing to do with gearing. you can change the tire diameter, should you expect a weaker motor? plus, who swaps out a tranny and keeps the motor stock? in any case, its not ratio's that are causing an increase in whp
how can ratios change the power extracted from within the cylinder? does that even make sense to you? if it does, then no rational explanation is going to work for you

thanks! And it sure did! :)
exactly my point.

Nice build and strong numbers that 4.6 final drive really bump up you're torque
dope
changing gear ratios doesnt change the tq or hp from the motor

are the dyno's exactly perfect? same exact tune? same temp? doubt it.
explain how h2bs out dyno full h22 swaps then?

Am Al the way in Jamaica bro I got the same engine. Wat did u do to make that power.
thats true good point but on average h2bs do out dyno full h22 swaps.
What oil seals did you use.
All OEM
From an h22 they fit f20b I just want to make sure thank you

hehe that reaction lmao
