Race legal at Qualcomm

Friday I went to street legal at Qualcomm. It is a 1/8 mile track. This is the firstI made few runs. Got beat by an STI, Evo ( he was moded), Mach 1 (I missed 3rd), and a Plymouth Scamp with drag slicks. I did beat a late model Golf GTI, Honda Civic and an Acura Integra GSR.

This is my fastest run.

R/T .758
60 Ft 2.514
ET 9.646
MPH 77.05

This is not a prepped track, it is basically a parking lot. I was getting wheel spin even when shifting into 2nd. Tuned Mach 1s where getting low to mid 9s. An 06 vette was also in the low 9s. I think his fastest run was 9.0.

Not too bad.

Yeah that track must be badly prepped. I've gone 8.32 on drag radials in my Mach and I have stock drivetrain (no tune, and stock 3.55 gears).

The Mach 1 that beat me did 9.614. Not sure if he was tuned or not. I talked to one guy who had a tuned Mach 1 with drag radials and he was getting low 9s.

I have been running at the Q for over a year now, and this is my best time

1.764 60'
8.227 1/8

That took a lot of mods and a little bit of practice. Plus the E/T streets help a lot.

What's your best time without the tires??

My best time was an 8.6 on street tires with cai/tune, udp's, cmcv delete's, and o/r h.

Last two times after adding lca's/relo's, gears, and driveshaft I can't get traction off the line and end up having to let off the gas.

BTW-auto tranny.

What were the STI and Evo running? They have incredible take-off traction so I'd imagine they'd be kings of the short track.

The STi that beat me ran a 8.6 and the EVO that beat me ran 7.5 (he was moded). Both of these cars were about 1/2 way down the track by the time I was done spinning my tires.

I was down to 8.9 on street tires, and went down to 8.4 with the E/T's. I will not run without them now.

So the tires alone netted you half a second?

What rims (size) do you run the e/t's (what size are the et's?) on?

I hope with more practice I will hit low 9s and if I get a CAI/tune I will shoot for high 8s.

I was launching around 2500 RPMs. Would it have been better if I was launching at a lower RPM.

I've got an automatic and I've always gotten my best times launching at idle.

Thanks. Next time if I decide to race there I will try launching at idle. I have also heard that LCAs would help.
