I practice alot! lol

The only other two cars I raced alot were my F-250 Diesel 4x4, which in 4 wheel drive, hooked no problem and pulled 1.8 60' times consistently and then my 94 NSX (R.I.P) which hooked easily with Pilot Sport Cups and a MOTOR sitting over the rear tires. I could launch that thing at 4,000 rpms and hook right up! Used to race Evo's and STi's out of the hole with ease!

Anyways, next weekend at the track, I'll give it a shot. It sucks up here because they spray down the whole burnout box so you can't stage around the water in order to avoid wet rubber. Stupid.

I'm gonna get line lock, which will help me with burnouts and gettin the rubber hot. I'm hoping if I can hook out the dig and grab going into 2nd, I can put it in the mid 12s. Thats about where a 108mph trap should be, isn't it??

I filled up the tank, reset the trip odometer, and drove the car in a very spirited manner this weekend. I decided to fill her up for the week (or so I hope). I put just 9.9 gallons of gas in, and the trip odometer was reading 140.8 miles. It averages out to 14.2 miles/gal. This was mostly city driving, stop light to stop light.

On my way to work today, I did notice that my highway rpms dropped about 100-200 rpms for the same speed (~80 mph). I think this is due to the under drive pulleys. Hopefully my highway mileage will increase a bit!

Didn't notice any changes with electrical when the UDP's went in. Don't have the shaker 1000 stereo as some have mentioned this could cause a drain with UDP's , then again others say not problems even with that.I don't really use the AC either,just drop the top!
