A lot of people will tell you to buy gears.stang4 said:I just bought an 04 GT and want to know what would be my best Mods. I was going to start with CAI, throttle body and plenum, what is a good one for the money and what other mods will help? This forum is loaded with alot of great info....:eyepoppin
I don't mean to steal the thread, but are gears harsh on the tranny? I really don't understand the concept of gears and how they make the car faster. Can you guys explain?blackfang said:You are wasting your money for really less than 10-15 rwhp. Gears are what is going to be very noticeable especially 4.10's. That car will feel like it has an extra 100 hp and 100 lbs of torque after the gears.
It's your car, and if you want to blow 400 on those mods that will do very little to a stock car, then be my guest. I will wait for the "man this sucks, I didn't feel that much of a gain" post from you.
How? I rather gain .3-.5 than .1 and actually notice a huge increase in performance. 10-15 was being nice on those figures.carguy1985 said:Im sorry black fang but if you dont want 10-15rwhp then thats kinda dumb something is anything.
That is your opinion, but the fact is 4.10's are on daily driven cars with 24+ mpg so the gears will not hurt the cars mpg. Actually the motor won't be turning"crazy high"(define that by the way?) rpms. In fact city driving he will be at lower rpms as the gearing will make 4th and 5th gears more usable around town and still be under 2,000 rpms. Too many people fear the gear, or don't understand them. 3.73's are a waste on a NA SOHC which revs to 6250 and needs gears to come alive. Either go do it right, or don't do it at all. 3.90 and 4.10's is like a 150 rpm difference which isn't noticed in mpg.and also, 4.10s are a little bit to much for a daily drive like i am sure his is. if you want more than 373s go with 390, but 373s are the safest, you dont want your motor reving crazy high all the time it makes a difference in the upper speed for example my car at 80 is just at 2500rpm, with 390s i calced it to be like almost 2800, the purpose of 5th gears is for overdrive. and if your 5th is like 4th then whats the point. i know because i was having this dilemma too.
The reason why gears show such huge improvement is because:blackfang said:Not at all. A bad driver and a ton of hp beyond the transmissions ability to hold and handle the power is.
The gears change the cars rate of acceleration. They causethe drivetrain to rotate faster in the rear end by the change of the gear ratios. When it spins faster it allows a faster rate of speed. It also multiplies the torque factor giving the car the feeling it has more hp and torque.
I have to agree with Jokers. My statement above only explained the effect of numericaly high gears - Personally I can not recommend it. In My '70 Dodge Challenger R/T I had a set of 4.10 gears, I hated them. High RPM's @ highway speeds, affects gas mileage, more wear on the motor.Jokers97GT said:You will have to excuse Blackfang and a few others. They like to get into shouting matchs every now and then. Gears will make your car seem like it has 50 to 100hp more, but if you don't want to do this mod yet then check into a good exhaust system (headers,h or x-pipe, catback) then a CAI, & throttlebody/plenum combo.
Who said anything about shouting matches? Where is this a shouting match? Looks to me it is a debate on what is the best bang for the buck, where i offered the right info.Jokers97GT said:You will have to excuse Blackfang and a few others.

These mods will add about 20+hp which will increase with future mods. Accufab is a good throttlebody/plenum kit for $399.00 for RMPOUTLET.com. If you plan on a supercharger in the future then get the 75mm kit, if not then a 70mm kit should be fine. BBK,Hooker,& Kooks make a great set of headers with prices starting about $400.00 & up for a set of long tubes (shorties are cheaper but you get more HP from long tubes).Exhaust depends on what you like so try to listen to every companys product and decide for yourself. K&N, Densecharger,& BBK makes good CAI's so check to see what brand looks good and makes good hp (research the companys product on line). Also underdrive pullies free up hp and are reasonably priced (try Steeda).
Compare the affects of gears on a 70's pushrod Big or small block motor that has more torque to an overhead cam torqueless motor :laughlittI have to agree with Jokers.
