Gearing....

[Fast SVT]

I was wondering if it would make sense to go with a longer gear in the Cobra for runs on the autobahn.

I'd like to keep the RPM's down while cruising around 120mph and changing the gearing shouldn't be a big deal on the street since it is a twin screw that already makes too much TQ down low.

Thoughts?

You can plug in some numbers here

I believe your 6th ratio is .62

Thanks. A Viper spec T-56 might help as well since it is different gear ratio's for 5th and 6th meant for higher speeds.

I'm going to see if Top Gear Motor Sports in PHX can swap out my 6th gear to the viper .50 as well as some other internal upgrades.

a buddy of mine had the viper spec T-56 with 4.30's in the rear. Even with that set up car had 2k cruising speed at 80 mph on the bahn. 120 cruising is a little overkill I mostly did 100 and even then I'm sure his car still maintained 3k rpms. My car would scream at 3500-4k at those speeds.

I suggest stepping up to a oil cooler for sustained runs like that.

When I was there I hardly used the autobahn and if I did it was mostly just to travel far or to have some fun.

I traveled often last time I was there and regularly cruised at 120 so I'm speaking from experience. Just trying to find a common sense way to keep the RPM's down and it seems changing out the gearing in 6th is the smartest way and won't change daily driving.

I was only saying a friend had the .5 final drive gear and it worked out great for him even with 4.30's. I didnt use the auto bahn on a daily basis so I really dont know how traffic is...Even cruising at 120 I'm sure Audi A6 and A8 wagons will still flash you, LOL.

I drove from east stuttgart to landstuhl in 45 minutes once...used 12 gallons of fuel too. 150-175 MPH most of the way in my POS.

Yeah, those station wagons fly on the bahn.
