Regardless.. having 150 mph top end is more than I care to go. So gearing the car wouldn't wouldn't have that factor to me.

 

oh, yes she makes house calls..

 

02-03 has the better ecu, thats the main important thing... other than the little things like tweeters in the doors and blah blah blah, chrome ringed tails etc.

 

stop by the dragon on friday after work if you are around... IF, i end up going gears, you can take my car at deal's gap and see how 4.77s feel.

 

Why must you tempt me like a siren Motoo

 

Fock, why do you have to keep making sense Pete?


By the way, the easier way to figure out your cruising RPM is to multiply whatever you have stock by 1.163 (for 4.77). If, for example, you're spinning 4200 RPM at 80 (which I think is what an AP1 does), going to 4.77 would give you about 4850.

 

Actually, that calculator is pretty slick.

 

The stock AP1 was geared out at around 170. The fastest I've ever heard claimed from a stock car on level ground was 153-155 on the speedometer, which is probably more along the lines of 149-151. The car just didn't have the power to push 6th gear. You might remember the video of the guy going balls out down a huge hill and pushing 270 KPH and bouncing off the rev limiter, but you needed the gravity assist (or FI) to get there.

The AP2 with 4.77 gears would be spinning just under 5000 RPM at 80 MPH. The only risk I see is that if you have a droning exhaust, 5000 tends to be the sweet spot (and by sweet, I mean deafening).

 

<---doesn't have a droning exhaust... (it rattles, not drones, and that's at closer to 2500rpms).
Just wonder 5000rpm wouldn't be too bad... my concern was the motor spinning around 6000rpms


do i need to go with a reinforced diff ?

 

Yeah.. I mentioned in one of my posts about drag limitations on a stock car. I think the calculator is slick but something seems off on it for the AP2.
