1. I have 4.10's on my cobra, stage 3 clutch. Blower. Want to go down in gears. Shoud i do 3.55 or 3.73? (Its a little difficult to get tracktion or drive around the city)
2. My after cooler~ should i just put water there in the summer and antifreeze mix in the winter?
3. Belt on the vortech s trim~ blower pulley is a little off (I think i need to turn the pulley around thats what vortech ppl told me to do)

I have ford 3.73 in mine but only putting down about 400 rwhp not your 520. I've been told by many people the 3.73 is best all around gear, and I'm not sure if you would notice a huge difference between 3.73 and 3.55. If tons of highway driving go with 3.55. Also I have my stock 3.27 from 99 Cobra in great shape if that option ever enters your mind let me know I will sell them very cheaply (aka $25). Also ask around at local shops too for more opinions on which to go with

i wouldthink you'll be dissapointed dropping all the way to 3:55s from 4:10s. Dont know though

01snake

i say keep 4.10's but throw et streets on

Ellik

your probably not making the low end torque that a Whippled cobra is making, so I'd guess that 3.73's would make up the difference.

lexy

yeah i was thinking 3.73's. If I get a good price for my Gt ill get a beater and keep the 4.10's in there. Just gas prices suck right now for 4.10s hehe

Ellik

tell me about it... Im running 4.56's.

ellik has a t-56, so for him, 4.56's are like 4.10's in a tr-3650.

on ur setup, u will be happy with 3.73's. if u had a twin screw, i would suggest 3.55's, but u don't.

lexy

Yeah thanks guys. How much power would that tranny hold the one i have in her? I'd think no more then 400? Cuz Im babying the car untill i get enough money to drop a new tranny in it.

u start shearing input shafts at around 500 whp or a little bit less, with traction..
