3.73 to 4.10
 

Just in case anyone cared about cruise speeds and RPMs, I changed from 3.73's to 4.10's. The "RPM per speed" change was....

3.73 gear
70 MPH/2400
80 MPH/2750ish

4.10 gear
70 MPH/dead on 2500
80 MPH/dead on 3000

This was using a DiabloSport Predator on both applications.
BTW, 4.10's FTW!

O yeah, this is on my '99 GT with a T45 tranny

Iwanna know if it helped. I'm betting it didnt.

OH yea. 4.10's now we are talking.

4.10s or nothing in a mod motor

Going from 3.55's to 4.10's in RoadPig made alot of difference...shoulda been built that way ... 55 mph is 2000 rpm on a modular 4.6L 32 valve ... Junior ... give a SOTP input from your drive of it because I am too use to it now ...

:gg:

Please explain your point in responding to my post

uhmmm...... he thinks your car is slow, and you made it slower by swapping to 4.10's.

Don't worry Brandon, thats what we at bc2 racing do all the time...... make cars slower. hehehe

yep, it got slower, thats for sure. Maybe one day ill have a lightning and a chevelle or whatever it is. I dont think I did too bad to run a procharged gt, me on motor, from a roll for fun and stay out front

nice. you are a procharger killer. i saw the video. remind me to avoid you.

Ill have to shoot the GTO tho...:poke:

Naa, don't worry about it. It's just another slow ls1.

Big f-ing difference in that land yacht. Wakes it up. I remember when my dad went from 3.27-4.10 WOW. Fox woke up a tiny bit from 2.73 - 3.55

lol. hey man you been busy with life. hope to see catch up with you soon.

Sorry if that came out wrong. Just wondering. Was thinking about 5.0 when I put that up. I knew some guys that have done that with a 5.0 car and it didnt help it. Forget about the 4.6 being more top end happy.

Really? I know of a 92 Stang that went from 3:73's to 4:10's and picked up 3-4 tenths, no other changes made. Then went from 4:10's to 4:30's and picked up nothing.

So far on the street my car is now like night and day. I love the 4.10, just not the RPM sacrifice, but itll be ok. Im hopin I can break into the mid 8's now! :hide:

LOL. your post is completely wrong. only 4.6 that's more "top end" happy than a 5.0L car is a 4 valve motor.

throw sticky tires on a 3.73 car vs. a 4.10 car and 4.10 car wins every time.

Thats the plan! :cheers

I see a tow truck in your future. LOL.
