91hatchgt

I am just curious to what I will run. I have a 91 GT hatchback with a T-5. I have done a MSD blaster TFI coil, 9mm Ford Racing wires, BBK headers, Headman catless H-pipe, and 4.10 gears. Any idea what I will run with good street tires? Just looking for an estimate.

15 flat from ur MPH...really low!! Maybe its altidiude

I don't understand... I meant, what will I run with the 4.10's?

bobby

he said 15 flat

No he said with my MPH (88.26) That I should be running 15 flat.

Id say with 4.10's you should be low 14's....I live about 1hr 15 min from palmdale.My grandparents live in there though. but yes. you should be in either low 14's with 4.10's or mid 14's. the palmdale track is pretty Sh*tty, there are better tracks around near Los angles a bit further away.

bobby

i dont think so, i ran 15 flat at almost 93mph

you have to have the motor to justify 4.10's simply slapping in gears will not get you the times you are looking for

Ok let me say this again. 15 flat!! 4.10 gears isnt gonna change his MPH enough to go mid 14s. Trap speed determins what you can run in the 1/4 mile. Unless you add some HP you aint gonna get into the mid 14s. You could reach high 14s but you gonna need a perfect run and some great sticky tires. It is possible that ur car is faster then the MPH you ran,Im assuming your run with that time was a good run. So im gonna say 15 flat.

i disagree. even thought it is a gt mustang the factory had some gas milage in mind and keeping the rpm low was the way to do it. a stock motor in your car with slicks and 4.10 gears ..if the motor is in good shape it should run mid to low 14's and of course the track and air temp.etc..plays a part in et also..
