N/A 4.6L 3 valves with 3.73 gears...

[Stephen06GT]

I would like to hear from those with the above noted combo. Are you happy with this ratio, How does it drive, what is the pull like in 3rd gear. If you've had any track (road course) time with this combo, I'd really like to hear about that as well.

Thanks
Stephen

On your door tag, Axle code CD is for 3.55 and CG is for 3.31

CD 3.55 in the axle currently.

Not much seat time but did drive a friends 05 with a CAI and 3:73 gears. Dyno sheets say my 3V with CAI and an X pipe makes a bit more power but his did feel "lighter" off the line and seemed to rev more freely.

We've never lined them up and to honest I've been avoiding it because I hate to loose.

I need boost.

I've got a '10 with 3.73's a C&L CAI and FR500 axle backs and love it. It is an auto not a stick and has nice pull off the line. It's fine on the highway, still quite comfortable. For me it was a big improvement since I jumped from 3.31 (auto) to 3.73 and the tune really improved throttle tip in and response.

I have an 07 with Roush CAI, hotrod cams, ford racing mufflers and a mail order tune. It's an auto and I have 4.10 gears. It runs 2500 rpm at 114 kph. I think that's fine. Love the 4.10's wouldn't go any other gear. I jumped from 3.31's to the 4.10's

Stephen, my 07 was switched to 3.73 when Rob owned it. Perfect compromise gear for a mildly modded manual 4.6 S197 I think. 6000 in 4th at the end of the straight at Mosport, and the gearing is good most corner on the tracks I've visited ... not too high for one gear or too low for the next as some axle ratios end up doing. Pulls nice on the street, and not revving the whee out of it cruising at 115-120 km/h. Mine was originally a 3.55 car same as yours.


cheers

Sorry to hijack but does anyone have gear thoughts for a boosted 3V?

Pretty sure 4.10s would make 1st useless so wondering if going to 3.73 is the right move from 3.55 or stay stock.

I'm pretty sure Scott B (Blackmare) is running 4.10's on his Whippled 3V.

All I can tell you, my own car is happy everywhere with 373's.
