Went to track tonight... sucked!

[Sivik]

Hey guys,

Went to the track tonight, made 6 runs... had a lot of fun, but also disappointed.

1) First, what should a stock 98 EX run in the 1/4?

2) I ran a 17.5 (best) and I only have a full intake. Best 60' was a 2.5. I ran against another EX (99-00) and he had a short ram, and he ran a 17.3 against me, and ran a 17.1 the other time. What they is wrong with my car? The time he ran a 17.3 we were neck and neck until the end (bout 2 seconds) and he pulled on me! Arg! Whats going on?

3) I had a bunch of stereo crap in the trunk, and I have 17" with low profile tires but would that really make a big difference? Between another EX?

4) I lowered my tires to 28psi (running 38) and I had my best runs. I'm pretty sure my engine needs a full tune-up and an oil change, but what can I do to improve my times?

Sorry so long, and maybe confusing but I'm confused, specially about the other EX beating me! Give me some ideas to help! Thanks!
