gears....3:73 or 4:10???

02wt5sp · 02-03-2005, 11:28 AM

I just went to a local shop(steen racing) and asked about gears, and all they could say is 4:10, I went in thinking about 3:73's and they laughed everytime I said something about them. They said with the new stangs(02 or newer with the 3650)don't go lower than 4:10, they even tried to talk me into 4:30's even when I said I drive 10 hours away once a month or so. Does anyone have 4:10s in a 02+??? If so what rpms are you running at 70??? They said about 2400, but that doesn't sound right, I think they were just trying to get some business.

Stevoneo · 02-03-2005, 12:56 PM

Wow. They are trying to jip you. Only go with 4:10 if it is track use. It can be done and work ok on highway, but with the amount you will be driving, kiss that motor goodbye. Stick with 3:73. That is your best bet. And you feel the difference.

*4.6 Love* · 02-03-2005, 01:34 PM

4.10 if your staying n/a, 3.73's if youre going with a power adder! :laughing1

kiss the motor goodbye??? Even if it was at 2700 at 70, I don't think It'll mess anything up, I was just worried about the noise, more than messing up the motor.

dude not to be dick but your telling people some very wrong information.
your motor will be fine with taller gears, only problem is that you will get worse milage and it will cruise at higher rpms. is this bad not really. also if you this worried about gears get the 3.73's.

Stevoneo · 02-03-2005, 05:22 PM

Look at how many miles this man will be traveling. With 4:10 he will be putting more wear and tear on the engine that with 3:73. You dont have to beleive me. call a performance shop and let them know how much you travel and what consistant speeds you will be traveling at. And your oil. Hope it will be fully sinthetic. RPM does stand for something, and think about that when your going 70-75 alot. They are not ment for highway use and any Drag-Racer who has been in the business will tell you the same. Leave those gears for the Strip not the highway strip.

WaterDR · 02-03-2005, 06:09 PM

Your first problem is you asked Steen Racing. I am surprised they did not tell you to get 6.10's. (lol).

If you get the 3.73's, you will most likely regret the decision more than you will with 4.10's. I say get 4.10's and don't look back. I had the same delema last year and in the end got 4.10's....glad I did. Actually, I wish I had 4.30's.

Can you find someone with 4.10's and test drive their car? That's what I would do if you are really worried. Spend some time in it on the highway and decide for yourself.

Stevoneo:

I appreciate your zeal and many will side with you. Fact is, I have never heard of a 4.6 motor ever going bad that did not fail because of something someone screwed up. These motors are good for 200k+...if running a few higher rpms takes some time off the clock, I really don't know if it will matter much in the end.

*madmatt* · 02-03-2005, 07:14 PM

Yea, look at all the peoples engines that have died from running a steep gear...oh wait, no Ive never seen any. Dont worry about your engine, but if you run chambered mufflers and have a lot of drone, be prepared to deal with it on a daily basis now that you have new gears. I went with 3.73's and sometimes wish I had the 4.10. Maybe the 4.10 would take me outta drone central, but im getting magnaflows anyway so oh well. Dang, shoulda done the 4.10s...

02wt5sp · 02-04-2005, 01:59 AM

see, that's what I hear soooooooo much.... man I should of got 4:10's, I think being that I can't deciede, that I'll go with 3:90's, it's right in the middle.

gtnumber2 · 02-04-2005, 07:47 AM

i have an auto that will rev higher, do to the one less gear and i bought 3.90s just because i drive 60-70 miles a day and its all highway. you will be fine with 4.10s. my 3.90s are going in april 1st when it comes out of storage for the winter. dont fear the gear.

Listen to him, if you go with 3:73s you are always gonna wonder "what if?" Don't waste your time and money, do the 4:10s. I have them and I drive a LOT! You're not gonna waste your engine unless your constantly running it to redline in every gear every time you get into the car. This track only talk is horse hockey.

Joshs96gt · 02-04-2005, 11:55 AM

Your drone masters are gonna piss you off at 70mph with gears in the car, I can tell you that much. You'll either have to keep it above 2,300-500 or below it to stay out of the drone range with your drone masters.

WaterDR · 02-04-2005, 12:49 PM

"Drone Masters"...I like that!

I have no idea what you are talking about because I have an SLP Catback and an X Pipe, so I can't even hear myself.....gears or no gears. For that matter, I can't hear any rattles either. SLP fixes just about every bad sound there is on the car.

Blue02GT · 02-04-2005, 05:01 PM

I have 4.30's, used to have 3.73's. With overdrive I can still cruise at 70 miles per hour and be under 3,000 rpm's. I get 22 mpg+ on the highway with the cruise set at 72 and 300 lbs. of racing stuff in the back . I drive my car to NMRA events with no problems ( 12 hour round trip). I would not listen to anyone who has not been there and done that. I did the 3.73's and they are better than stock but 4.10 - 4.30 is were it's at.
Oh and I rev and hold at 6500 rpm doing burnouts so 2,500 - 3,000 rpm cruising is nothing. The guys at Steen know there stuff, I would listen to them.

you overdrive is .62 in the t-3650, t-45 is .68 at 70mph. I run 2700 in my 98.

I drive my car with 4.10's 82 miles a day just as a commute to and from work, the car has 109k miles and I did a compression test 3 thousand miles ago and my numbers were Extremely healthy for the mileage ranging from 175-192psi.

Steen knows what they are talking about, you will LOVE 4.10's, the only way I personally would back down a gear is for a power adder and then with my car i would step to a 3.90 so that I would be crossing the traps in the sweet spot of the HP curve.

the guy who said you will blow up your motor is an idiot, I suggest you try a few more sites for advice. The number #1 for technical advice on modular mustangs is modulardepot.com I am on 10 mustang boards and it is by far the most technically sound one i have found.

I'm happy to find this board, though, you can never have to many people to talk to about mustangs.

What are your plans for the future? What I see is the norm or conservative selection of gears is the SOHC 3.73 GT and DOHC Cobra 4.10. If you want to purchase 3.90 look here as a fellow member has one for sale http://www.mustangtuningforums.com/showthread.php?t=974

$125 shipped is a steal!! I doubt they will stay unsold for too long.

Best SOTP cheap upgrade you will get is gears!!! Back in 1990 I bought a 1987 gt that had a AOD automatic and 2.73 gears!! To top it off, there were BF Goodrich Radial TA 265/60s which is almost a 28" tall tire!!you wanna talk about a dog off the line!!! 1250rpms @ 60mph!!!!

I switched to 4:10s and Destroyed those hard radial TA's i could barely spin before that weekend!!!

4.10s are nothing with overdrive. Before the T5s came out and AODs, Imagine haveing that c4 and 4:10s.

My first car was a 1970 Mach1 351 Cleveland and a C6 tranny, I put 4:10 gears in it. Try 3400rpms @ 60mph, Speedo i was broke, I remember.

Changing to 3.90s or 4.10s is no sweat on the highway, .62 OD will hardly notice.

thanks for looking out, i'm redoing my rearend and am backing down to a 3.90, I am looking at an NX kit in the future.

BLoWbyU · 02-06-2005, 11:47 PM

on stangnet.co there is a sticky vid of a 99GT with 4:10 gears,actually he posted lots of vids with them-very usefull info....the guy's member name is spreadman, its in the modular 4.6 forum.

What he said, (I have the same set-up), but if you're referring to a drone from the gears, fuggedaboutit. Nary a peep.
