I drive a 96 Z28 with some goodies on it that has me running 12:90 @ 108. Thats with 3.73 gears. Engine mods staying the same, if I were to down grade to 323's what kind of ET/trap loss would i suffer? Gas prices are a bi*ch in FL. Just curious?

i dont know but i have a set of 3.23 if ya want to trade.

I'll trade you and kick in a few bucks.......

SOrry guys , the bearings , gears and everything are shot. Im thinking of dropping back down to 323's because of high gas prices. I just want to know how much 323's will slow me down seeing i run a 12:90 with 373's

hmm around .2 or .3.

I wouldn't think it would slow down your final time, just your acceleration. But then your top end power would be a little faster. So it's hard to say. Try it and let us know

MPZ28

Hmm, sounds good. I've never had 323's in my car so, the 323 feeling should be fun for those 45-50 mph roles.

How would the top end power be faster with a lower numerical gear?

MPZ28

good question but, 323 gears are a new animal to me so , i guess im in for some kind of change ?

kainZ

The 323 feeling? I don't know what you guys are talking about? 373s will give you faster acceleration in any gear at any rpm, assuming you have traction...

MPZ28

thats what i thought, 323's are going to slow me down all around the tack.

kainZ

Think of it like multiplication, and ignore the tranny (pretend 4th gear on an M6):

Engine RPM * Gear Ratio = Output RPM

Increase the gear ratio number, and you increase the speed at which your wheels spin per engine revolution. The faster your wheels spin, well, assuming traction, the faster you go!

I think i only gained 3 or 4 tenths by swithing to 4.10s from 2.73s. Maybe you could make a comprimise and run 3.42s which are a good gear, they work great with n2o.

kainZ

Well, if you have no traction with 3.73, you might go faster with 3.23, because you'll spend less time spinning your tires at the line... but if you can drive 3.73 at the track without wheelspin, then yeah, you'll probably lose at least few tenths with 3.23s.

Apparently there are some confirmed otherwise stock 5spd Mach1 Mustangs which switch to 4.11 rear end gears and slicks and run low 12's at the track (Launching at 6800rpm with no wheelspin). Granted, these guys must be great drivers, but that is impressive.

Note: I say apparently confirmed because I have yet to see this in person.

lmao @ " My exaust sounds better then your stereo" I just put on Magnaflow cat back with jet hot long tubes. Sometimes i leave the radio off so i can listen to my car.
