went to the track today, not very happy, last time I went my best was

14.467 at 95.48.... 2.20 6oft. 1/8th mile 9.315 at 76.85mph.


this time:

14.622 at 94.77mph. 2.161 60ft. 1/8th mile 9.440 at 75.49mph w/.070 r/t.


my worst today was a 15.121 at 93.89 2.42 60ft. I was spinning bad.
I have been having people telling me that my trap speed is really low. should be 98-101 not 93-95mph. car seems to be running fine..all stock except hypertech chip,moroso cai,stage 2 shift kit. magnaflow catback.

car is 93 ta. with a4-323's.. around 130,000miles on it. do you think new plugs,coil,wires would help...dosen't seem to be missing...I just notice that every other car I race seems to have a higher trap speed even if I win..like today I beat a srt4... my 15.121 at 93.89. to his 15.004 at 95.21
but my r/t was a .372 to his .774 so it says I won by .2853 which was to close....

sorry for long post. but any ideas why my trap speed is so low..thanks..

 

Do a compression test.

 

Oh and a problem with higher mileage cars is sometimes a clogged fuel filter or a tired fuel pump.

 

Whats the altitude like?

FWIW my bone stock 93 auto ran 14.5's at 95mph.. some are just slower tan others.

 

If you went to mokan that track sucks. Nothing good about that track. my best with my mods was a 13.9 i think. Go to Rogersville (OIR) that is a little better.

 

Ditch the hypertech and get a pcmforless tune.

 

dont be too hard on the times cuz mine was running 14.3@96 with the same mods. i was a little mad too, but i bought a stall and put some LT's with some sticky tires and ran 13.03@101(??). also work on those 60ft's and you should see better times. with sticky tires and good weather you can get into the 13's or damn close.

 

i was running 13.8's on a 100 shot because my fuel pump was pretty much shot and wasnt getting the fuel i needed. Well I upgraded to a 255lph and a 150 shot and beat a 13.0 35th SS by 2 - 2 1/2 cars last weekend. So I think the fuel pump really helped me

 

yeah I went to kcir off of noland rd. I believe that is mokan..the weather was about 87 degrees and humid. thanks for the replys, Ive had the car for about 6 months. I am going to change the plugs,plug wires,coil. fuel filter and a 255gph. fuel pump...that does drop in the tank dosen't it, and can I go in thru the floor of the car. and does it wire up to the factory fuel pump wiring. thanks for all the replys... and hopefully by the end of summer, I am going to get some jett hot Lt's... and some dr's

 

Ya can't change the weather.

 

130,000miles ... Your engine probably can use some nice reworking if your serious about cutting times. I think those are pretty good times for the mileage on your car, and the minimal mods you have. Can't expect an older engine to run as hard as a younger LT-1.

 

Why not? 130k is not over the hill. Mustang 5.0s are proven to get faster once they get over 100k.

Do a good tune up and it will run fine.
