99-00 mods

cdloc · 12-09-1999, 11:05 PM

Has anynone read this months mm&ff issue? There is a article on a 99 Gt that was equipped with several upgrades kn,mass air meter,tb and cat back exhaust with all this they were only able to get gains of around 10hp. I was the wondering how Saleen is able to get a 25hp gain with only kn,pulleys and cat back exhaust. I guess my question is, are the saleen claims alittle optimistic or is there something else done to these cars that Im unaware of. I recently purchased a 00 gt and am looking to upgrade it so I want the most bang for the buck.

They only other thing that I know they do is they replace the ECU. It does sound like a lot from just those mods. I can tell you that I drove both a '99 GT and and '99 S-281 and the S-281 felt much stonger. I don't know that it felt 25 hp stonger, but it was stonger.

I have a 99gt dead stock.it made 241 Rwhp & 284 rw torque. I installed a K&N, 2 charber Flowmasters, A cheap offroad h pipe. and a used C&L mass air meter that I'm not even sure if its desinged for, and picked up 19 rwhp (261.7), my peak torque decreased to 281.8 which really disappointed me, but I installed 4.10's and was told that gears have a negative effect on the dyno, don't no if its true, but it helped out my moral slightly. If anybody can verify this let me know, also is the c&l 96 calabration the same as what they are using for the 99, only paid $100 dollars for the meter and filter, If its not I should be able to get money back out of it as it retails for $299.

Most bang for your buck. Simple 3.73's. Do everthing else afterwards except maybe the K&N.

cdloc · 12-11-1999, 05:25 PM

What brand of gears do you reccomend? Also how would 3.73 gearing effect the car on the freeway.

RedGTvert · 12-11-1999, 05:52 PM

FMS (Ford MotorSport). The only effect it will have on highway driving is your R's will be up about 500 or so. You'll lose a little top end MPH, but do you really plan on doing 130. You'll also find if you are a 5 speed, you'll use fifth a little more in places you normally wouldn't have. You gas milaege might suffer a tiny bit, but with the extra push you'll get at the bottom end it is well worth it.

You will also have to get a speed compensator with the gears. There is no speedo gear to correct speedometer on the 99/00's. I use an Abbott ERA also I have head good things about the one from Sean Hyland.

You can get both the gears and speedo compensator from Houston Performance.

I totally agree....
A 3.73 gear change will give you a good bang for your buck and great seat of the pants acceleration. They also get you into the powerband faster...A great mod.. ;-)

Thanks for the input. I think Ill put that on top of my list. About how much will the speedo compensator set me back. Also how does this work?

RedGTvert · 12-13-1999, 11:00 PM

I use the Abbott ERA, Houston Performance sells it for $120.00. Whoever does you gear can probably install as well.

There is no speedo gear on 99/00's. I don't understand completely, but there is an electronic signal sent that the compensator changes the signal or pulses somehow.

If you ever go to a lerger set of tires and wheels, the compensator can correct as well.
