Slow down...ask a question in a complete sentence, and you will get replies.
I don't think anyone here holds grudges. We all want to learn from each other. If you are here to impress others, than you are in the wrong place.

So what do you have a specific question on

 

[hotrodman]

i do have a 99 cobra it does have 298 rwph. what i want to know should i leave the 3.73s in it if i want to get a procharger. ,,or would 4.10s be better, i think 3.73s, what do you think???

Gears

4.10's suck for drag racing on an NA car, but if you are putting a Procharger on then they are perfect. 3.73's should have never gone in on such a high revving car. 4.30s (maybe even 4.56) are the perfect gear for an NA Cobra. If you really are planning on supercharging soon and want a beast put the 4.10s in. If you want a safe tune street car that doesn't hit the strip then go 3.73s. I would say 4.10s though. Good Luck.

No headers, I still use the stock manifolds.

what do you intend to do with the car? Drag race? Open track?

I don't know...i am boderline switching to a 3.73 gear.The 4.10 was great n/a but with the D1 traction is non existant on the street.If you do any highway driving you may want to consider leaving them in if you are going with a procharger.Just my opinion.

4.10s, Blower, and trying to dig off the line at the track, with IRS, is a PITA.

But street racing from a roll, how sweet.

put the procharger on first and worry about the gears after the blower setup is done

hey i got a 99 cobra got mac l//ts headers my car smokes real bad use oil 6 qts. 1500 miles.never smoked before my comp.is good 170/175,,leakdown is good i think from 3% to 12% how is that ?? should i put stock manifolds back on??

 

[Firme]

for road racing, I would go with 3.73s
but I agree with RydeOn, put the blower on first, then worry about the gears.

 

[KU Cobra]

With the supercharger I would scrap the MAC lt headers, they suck ass. Pick up a set of JBA headers. If you aren't going to supercharge just put the stock manifolds back on.
