lets say figurtively speaking you have a 94-95 cobra making aprox 365 rwhp...what rear gears would be the best for this 5.0 vortech system to get the best performance?
thank you
thank you

ok so i have some 3.73's to put into it, but i think it might be a little too hard to keep the wheels from spinning considering i dont have anything but street tires on it....i mean figurtively speaking

3.55's are a good power adder gear. 3.73's will be fine, but you might be shifting pretty fast in the quarter mile.

with a stock motor and a blower, 3.73's. With a motor that spins to 7k and has a blower 4.10's.
This is only my opinion, there are other good ideas.
4.10's with a stock supercharged car will probably get into 5th gear at the track and you don't want that. But if you have H/C/I and a blower I fell that you could use 4.10's and 4th gear would be about maxed crossing the line. I have 4.10's and want to get a blower, but i think I will build the motor first so I can keep my 4.10's.
A blown 331 with 4.10's would be so fast. oh gezzz, I'm going to wet myself.
p.s. Spinning is fun.

so you guys think i would be fine with a stock motor and blower and 3.73's? my mechanic thought i would be shiifting too much....but i dont know if he knows an apple from a bananna....so yeah...i thought i would be ok too because of some other posts i have read...but when he said that and i couldnt decide 3.55's or the ones i just got last week which are 3.73's... and i have been also reading posts about the speedo being off and also the odometer...should i even attempt it myself or should i take it to my mechanic who tells me it would take 6-8 hours to do....($240-$320) and who also may not know apples from banannas sometimes as stated before.

I did my gears, but it was very time consuming without the right tools. I also have a little whine due to the lack of a pinion depth setup tool. You need three tools that a normal mechanic will not have if you're just doing a gear swap. These three tools are a pinion depth setup tool, a backlash tool, and a press. If you have all of those tools, then the installation might be easier, but if I had to do it a second time, I'd get somebody to do it.
3.73's to 4.10's with a centrifugal blower
3.55's to 3.73's with a positive displacement blower
3.73's seem to fall right in the middle of both.

With a T-5 & stock size tires the max speed in 4th gear is ~ 120mph at redline (6k rpm). You'd need alot more than 365rwhp to have to shift into 5th at the track. Stock engine + S-Trim I say 373's for a daily driver, 4.10's for a 1/4 mile terror. 4th would be good till ~111mph, and if thats not enough you can always go a little taller with the tires. 4.10;s would be a very nice gear because you'd end up almost exactly at redline at the traps, assuming ~360rwhp.

355s, especially with a roots or twin screw blower. You could probably get away with 373s if you had a centrifugal blower. I think 410s and a supercharger would be overkill.
so far i think that the majority of you say 3.73's should be good....a few 3.55's in there. but are there any people in here that have a supercharger and gears and tell me if they do like them, or dont, or what they would change to make it better?
thanks

so 3.73's sound like the way to go for me...i guess i will go ahead with them, unless anyone else has good cause as to why i should do something else...
ok got ya.....
i think that i am going to just go ahead and do the 3.73's....
did any of you have the 3.08's while supercharged, then switch over to the 3.73's ? did it sill make a huge diffrence? i know alot of people on here talk about it being a diffrence between night and day when they get gears...i just wonder if it is the same size of diffrence when supercharged....

roots style=Kenne Bell, Eaton, like on the 03/04 Cobra's.
I say go with 3.55's. 3.73's would probably match that HP really good, but if you add more HP you'll be running out of gear in the 1/4. A friend of mine has a Vortech'd 347 with 3.73's and I think he was going back to 3.27's because he has to shift into 5th with the 3.73's.

Yeah, but unless you're running over 120mph in the 1/4 3.73's will be fine. You can always go to a 28" tall tire also.
