Whats the Big No-No with 4.10's and a SC

[derek02gt]

all the adds ive read say go with 3.73s if your planning a power adder, can somebody please explain this..like whats the reason? and how do 4.10's perform with a Supercharger?

From what I've heard, it's traction.

You won't be able to hook with 4.10s and a SC.

Maybe full suspension and some DR's will help, but if you don't do all that, I'd say get the 3.73's.

Many people will run out 4th gear in the quarter mile when using 4.10 gears.

Yeah, I would say it is because of traction.

I wouldn't even consider getting 4:10's in my car. Traction sucks as it is. It's a good and a bad problem to have.

Most say traction. I've got 4.10s now and the rock N/A but I don't know how they will turn out when I go the S/C route. I'm definately going to keep them on and see how they turn out, but I'll probably end up replacing them with something else.

It sucks to run out of gear

 

[jadesville]

all i've heard is 3.73 or 4.10's, has any tried 3.90's with their s/c, or is that still a traction and running out of gear issue? or is that even worth it?

 

[4.6MustangSteve]

Hmm, I don't think you'd run out of gear with 3.90's. In 4th gear at 6,000 RPM with the 3.90's you'd be at around 117-118mph.

that doesnt seem bad at all, what about traction?

 

[4.6MustangSteve]

Well I'm sure with some sticky tires and a good suspension traction wouldn't be much of a problem.

maybe ill just have to give it a shot once i get a new car

i guess i should try to find some more info on 3.90's

There's a cure for it.

It's called changing your rev limiter to 6500 RPM. A nice set of valve springs helps, too.

Right. My rev limiter is set at 8000 rpm. I have 4.10's with a Novi 2000 and 28 inch slicks. I shift at 7000 rpm and trap at 130 mph in 3rd gear with a 4R70W.

 

[inertia]

running out of gear, traction, and high RPMs. But thats what Slicks and raising the RPMs are for.
