Hey Mustang92!!!

Mustang92, i hope you read this message....

I saw your post about the 4.10 gears..and i saw that you have steeda UD pulleys and a TA adjuster. I have a 2001 GT and i just bought steeda UD pulleys and the TA adjuster. im about to install them and i already got my tank full of 92 octane. I wanna know something and since you have the parts on your car already...

What timing can i safely do on my (otherwise) stock engine? i heard 12-13 with 92 octane is max safest, but what timing do you think is good? also, is it safe to throw a bottle of octane booster into the tank along with 92 octane gas? with the octane booster, could i bump it up another couple degrees?

Also, how difficult is it to install 4.10 gears, and where can i get my speedometer recalibrated? i dont wanna pay $400 for an install and i dont wanna pay $150 for the computer. i got lots of tools and have messed with lots of cars but ive never done a rear end gear install.

Please letme know either reply to this thread or email me at blueshuttle@earthlink.net

thanx!!

Blue, I'm not Mustang92 but I can give you some input to your questions. The T/A on my car is set at 14 degrees. I run 92 octane with no pinging issues whatsoever. I definetly felt a real noticeable gain in low end torque with the T/A set at 14. Most guys seem to use about 14 to 15 degrees. So I see your thinking about 4.10's. From what I hear thats a awesome mod, really helps with acceleration. I got 4.10's sitting in my room and I am looking to install them soon. I've been calling around to get a good deal. One quote I got was $500 for labor (yeah right). Another place I called was only $300 for labor so that's where I'm probably going. As far as recalibrating the speedometer after the gear install, you could call Dallas Mustang they have a device that goes for about $100 and allows you to calibrate the speedometer by tapping into some wires and setting a few dip switches. Hope this helps for now.

black281 pretty much answered your questions. Just remember more timing is not always better, our cars stop making more power at 15* or so after that you start to lose power. I've had mine up as high as 18* on the dyno with 93 octane with not detonation but the car made the same power as it did at 10*. 14-15* was nearly identical on the dyno so that is where I tend to keep it set at.

Gears are something you want a professional installer to do unless you've done that job before. I get mine done for $175 locally but average seems to be in the $200-250 range usually. If you know someone that works at Ford they sometimes will do the job on the side for pretty cheap.

thanx for the info alot guys, i will keep that in mind when i get these toys bolted on.

By the way, does octane booster do anything for these cars with TA? is octane booster even safe?

Mustang92 · 03-21-2002, 10:55 AM

Adding octane booster will do nothing but slow you down. Higher octane fuel burns slower than lower octance fuel this is why supercharged cars use it to prevent detonation. When a car uses a higher octane fuel than what is needed it is burning just as slow and thus reducing power.

allright, so I will forget octane booster!!!

Allright, if you can believe it, i got more questions!!

I looked under my car, (2001 GT 5spd) and i dont have a center drain bolt on my tranny, which means i do NOT have the 3650

instead i got the side bolt
So what tranny do i have? ive heard a few different names like "t-45" and "t-3550" but what tranny does my early2001 GT got? i wanna know so i can buy the correct short-throw shifter...

Also, you are gonna be mad but i decided instead to get 3.73s. see , this is my daily driver and i am often on the freeway late at night and i dont want to be at 3200rpm when i set the cruise at 75. SO im doin 3.73s for now. Well anyway, i have a best time of 14.56 at the Los Angeles County Raceway. Its 2900ft high, and about 45-50 degrees outside, bone stock. I backed it up with a 14.63.

So this weekend i am installing a triple hitter of: 3.73 gears, Steeda underdrive pulleys, and Steeda timing adjuster. after i install everything, with 92 gas and 14 degrees on the TA, what times can i expect when i go to the track? will i break into the 13s? should i buy a helmet?

Please give me some insight, i want to be prepared...
thanx!
