My friend wants to gear his 2v GT. Hes thinking of a 3.73, but im trying to get him to step up to the 4.10. Now i know in the 4v the mpg is not effected by a gear change (or minimal) is this the same for the 2v? This is a daily and he drive the car a lot (also is poor college kid)

I've been driving a 4:10 with a Novi 2000 on the street for 2 years, this was my daily driver, gas mileage was about the same, it did drop a small amount on the highway but it was very very minimal.

4:10s would lower his MPG by alittle bit. Its all in how he drives it. 4:10s are fun and cheap hp and acceleration.:burnout: Moding a v8 of any kind and not wanting to lower the mpg doesnt go together.:nono:

Don't fear the gear. He should go with a 4.30 if the car is NA.

If he doesn't have the balls to put a 4.10 in the car tell him not to spend any money on his car.

Heck, a girl with an auto I know on another site put in a 3.90 gear and said she should have done the 4.10 at least.

He is new to the mustang market and performance market in general. I think 4.10 would be good, them little 2Vs arent as good in the upper RPMs so 4.30 might be much.

Depends what his goals are for the car. 4.30 vs 4.10 is basically 15rwtq in exchange for 2-5mph. He'd top out 4th around 105 on stock tires. Stock 2v's trap under 100 in the 1/4

^^ That's affirmative. Full boltons + tire + 4.10 put me trapping at around 5200 rpm's on motor (little room leftover). On spray, i was right at the 6k mark at 1320 feet.

4.10! I've heard that it feels like an extra 40hp. I will be doing 4.10's in May, but I do 95% city driving. If he does a lot of highway, then he will probably see around 23 mpg with 4.10's. On the street mpg shouldn't change much, that is if he can keep his foot off the pedal.

What was your time and mph on all motor? I'm hoping to be in the 12.90's with 4.10's and M/T ET street radials. My best so far with full bolt ons, stock gear, and street tires has been a [email protected] w/ 2.05 60'. Race weight was 3525lbs. The car puts down 266/300.

I only raced a few times on motor w/ the 4.10 and 26" slicks, never really trying to get the best time out of the car. The gear really only took 2/10ths off my time. It ran 13.5's @ 103 all day on motor. I was going easy on the car these runs (light launch and no powershifting) because the diff had just been rebuilt and it was the cars first time to the track that season. Only other time i ran it on motor at the track was MSC and i dialed in a 13.5 and stayed pretty close to that all day with easy driving. On the 100 shot it ran 12.4's rather consistently powershifting and launching hard. I hit 12.6's with the stock gear and 17 inch BFG DR's (big ass burnout...like huge). And hit a 12.4 (consistent 12.5 no problem) with the slicks and 4.10. I expected the gear to take more time off, but such is life. It sure as hell felt faster driving around town though.

hmm... seems like you should've definitely been at a 13.0 at least on slicks. I'm hoping for .3 from the 4.10's and a 1.75 - 1.8 60' out of the M/T's, which should be good for another .3 - .4. I will never powershift my car. I always do a complete lift, and pull/push the shifter and fast as possible.

I drove a 3.73 01 GT with a 5spd. Minor bolts ons. Very suitable for the car.

I TOTALLY disproved the rule of every tenth in the 60' is 2 tenths in the 1/4. I saw an equal gain, tenth in the 60' gave me a tenth in the 1/4 (if that). Raced on a bunch of different tires, stock gear vs. 4.10 gear. I've had every short time from a 1.58 to a 2.1 (thankyou, NITTO) 12.90's seem to be a rather lofty goal. What all have you done since you ran the 13.6? You don't see very many Bolt-on 2v's in the 12's. I have yet to see one, actually. There was no way my car had a 13.0 on it on motor, not even close. Maybe I could have gotten a 13.3 in perfect conditions, but i doubt it. I'm reviewing the vids of it right now and the runs look good, only thing that could have improved them was powershifting. Sorry for the thread Hijack...but i know u don't care JD lol :)

Haven't done anything since the 13.6 (once again, this was on BFG KDW II's with a 2.05 60' launching at 1200 rpms). In May will be doing a built rear with 4.10's, steeda sport springs, bilsteins, and MM lower control arms. The norm for guys with similar mods seems to be a 13.0 - 13.20. One guy from chicagolandmustang (think it was 03geetee) ran a 13.10 with full bolt ons, 4.10's, on 18" chrome roush wheels on a BFG drag radial. Another guy from Wisconsin went 13.50's with full bolt ons, 3.90's, eibach sportlines, on Sumitomos at GLD. I'd be pretty disappointed if I only went .3 quicker with the addition of 4.10's, control arms, and M/T's. I'm pretty sure 13.50's will be possible on street tires going off of idle, and a very low 13 @ ~ 105 mph launching at like 4500 rpms on M/T's.

City drivng mpg increases with a gear, and highway goes down.

4:10's will allow you to trap between 122-124mph depending on if your using a slick or not and if your running to 6500rpm, 3:73's will allow you to trap between 134-136mph. I'm stepping down to a 3:73 due to hitting the limiter before the traps because of my gearing. On a N/A car and even one to be supercharged in the near future I'd still recommend a 4:10

I ran a 13.00 @ 104 with just a tune, midpipe, spec stage II clutch, flowmaster catback, 4:10 gear with a built rear and minor suspension mods (shocks, FRPP C-springs) and a rear seat delete, think I cut a 1.7x 60" (if I remember right) this was on a slick in cool weather though.

4.10's will put him at 112 mph by 6,000 rpms on a 26" tire. Don't know of too many people that are willing to rev to 6500 rpms on a stock motor.

Exactly! It doesn't take that much to go 13.0 .

He won't be anywhere near 112mph with a bolt on NA GT. Crossing the traps at 6K is perfect.

As the owner of a 2000 GT w/ 3.73s, my gas milage dropped from 22mgh on the highway to about 18-19mpg. Additionally, it slowed my track (real race track, not the 1/4 mile crap) speeds on long straights because I went into 5th too early.

I say either stay 3.27 or go 4.10 for performance. 3.27 for MPG

If your on a budget and need bang for your buck, you cant beat 4.10s and a sticky tire.

What kind of race track are you talking about? With 3.73's you shouldn't have to go into 5th until you're at around 120mph, and they should help you accelerate quicker. If you're looking to go faster, or for top speed, you need a lower gear like a 3.55 or 3.27 and some horsepower to get the car moving like a Kenne Bell. Gas mileage shouldn't have dropped under 20 mpg on the highway. Never heard of a jump that big. I've heard that with 4.10's you'll be getting around 22 mpg on the highway if you keep it around 70-75 mph. With my 3.27's i get 25 mpg.
