Hi,

did some searches but seems like there is a ton of information on the 4.44 and 4.77 ratios. However, there are no hits for 4.9 FD ratio.

anyone installed and has some comments on this setup for an AP1?

am trying to decide between the 4.7 and the 4.9.

thanks.

 

i had the 4.77s they are great for stop light to stop light, the 4.99 would be tooooo aggressive thats probably why you dont.

 

That's just overkill....

 

thats wat my mechanic told me too.. just wondering if it really is too aggressive...

does anyone have calculations on RPM of 4.9 at 60mph?

overkill...














...do it.

 

hmmm.. at 60

4.9 is 4k rpm
4.77 is 3.8krpm.

doesnt seem like a lot of difference...

 

do you really only cruise at 60 though?

 

it's an ABSOLUTE no if you drive highway often.

 

NO on your 4.9 idea. 4.77 is agressive to begin with. you will be in vtec or in and out of vtec constantly at freeway speeds i would think,
