Hi Folks,

I could use some suggestions. I have an 02z with an intake, headers, exhause, and large cam. I also have 4.10 gears, which the previous owner had installed by ECS . With that said, I am looking to either add a supercharger or nitrous (150 shot) to the car. Here is my issue:

The tall gears are great with the larger cam I have. They help out down low a lot. Yet, if I supercharge the car and am around 600rwhp I am thinking I will have too much gear and will need to replace them, which will cost more. The other option I am considering is a 150 shot of nitrous.

My questions:

1. Will 4.10's be useless due to traction issues with a supercharger?
2. Does 4.10's make more sense with a nitrous setup given my situation?
3. Any other comments or suggestions welcomed.

Thanks for your time!

if your going to put a blower on the car, id definitely ditch the 4:10's and go back to a 3.42 or a 3.73 max, but that's me.

hope that helps.

huge fan of nitrous! Im probably going to put that on mine
thats the route i would go

Thanks for the feedback. 1 to 1 is the score

Blew my camaro up on n20 and seen to many blow up with it... Not a fan! I am going with a p1sc procharger kit on my c5 z06. N20 I hated always filling the bottle. And than in the middle of a race you run out it blows. The procharger's power IS ALWAYS THERE. Imo it's kinda dumb to pick something because of the gears you have. Gears should be picked off of what you want to do.

I understand your position, however the gears where already in the car, so they are what I have to work with.

IMO gears are always a piece of the puzzle. Although I'm a little confused about the purpose of the power adder (your worried about traction on the street or track) ??

Do you have traction issues now ?? What power level now ??

Mostly a street car that may see a drag strip every once in awhile. I would assume wheels/tires are the big issue on the street. Correct?

Traction from a roll is fine for the most part, but from stop it will spin. Car is at 440rwhp.

My concerns comes from people around me that say 4.10's will lead to lots of traction issues on the street with the power a supercharger would make.

If we are talking track: do you think the 4.10's are good if I had the tire to stick?

Another consideration, with 4 10's and a 150 shot, you will run out of 4th gear before the 1/4 mile. Shifting to 5th in a drag race is chancy, depending on your skills.

Ok sounds good. It sounds like the gears need to go no matter what I do, unless I just leave it NA with maybe some heads.

And that's why your slow and have no car!!!

If traction is an issue, you fix the issue with tires or other things, you don't bandit or cut it out....if you are roasting your tires at 600 in first gear.. you simply cant drive... there is no sense is burning tires on the street like that.. which you can do with a stock car as well..

LSOHOLIC

As Josh was alluding too......by removing the gears your "in a sense" bandading the setup. Kind of reminds me of guys doing a bad *** head/cam setup then throwing heavy azz 20" wheels on and killing the power....crazy imo.

The real answer is in rollout....but you also need to do your mph/gear math as well as rpm drop/shift extention numbers to be 100% sure of the correct combo.

But IMO I would not remove the gears !! 325/50-15 MT DR's and let her eat !!

Ok thanks. I think it makes sense to try to actually fix the problem with tires and driver mods . If that does not work, then I will consider other options.

Againk, thanks for the opinions.

Gear it for what you want to do, certainly not just because someone tells you. Have a reason. If you go to the track, what kind of power are you wanting to end up with and more importantly figure out what the trap speed will be for your tires, etc.

For example, I want to end up trapping low 160's and don't want to rev it much past 7k with my 402TT. I had 3.90's in it from the last time I built the diff, and on a 28" tire that puts me at ~149mph in 4th at 7k. So, I just re-geared to 3.42's so i'm at the top of the power band for where I want to be eventually with some room to spare. I build these myself though, so only costs the gear set and some time for me.

ONE MORE for keeping the gears (and cam). If you went with a supercharger, you would most likely have to replace the cam that's in there now - and the gears.

Who wants power on the street with 3:42 gears and a supercharger anyway? Heads cam is much more responsive and fun

I say keep the heads/cam setup you have now, 440 rwhp must be a blast already...and drop in a NANO system for those times when you feel you need a little x-tra!

And I agree with Caleb about the tire ... we got that from watching street outlaws

Had 3.90 in my car with blower at 800+hp, with sticky tires to. it was a blast to drive.

the question that needs to be asked is what do you want.
i can get you a good deal on a NX system if you want to go that route, just pm me.
