Hey. I own a 00 Si with the following mods:
-Custom built turbo kit by www.DCPTurbo.com at 8psi. (making around 230-240whp)
-Toyo Proxy T1R's 205/50/15 (stock SI wheels)
-DC Sports short shifter
-Clutch Specialties Stage 4 clutch
-Hawk Brake Pads
-Power Slot Rotors
-Koni Yellows
-H & R Race springs
-Skunk2 Front & Rear Camber kits
-Polyurathyne Engine Mount inserts
-N1 Cat-back
I went to the track last night for the second time since I turboed my car. I couldnt hit 13's! I trap 104mph but my fastest time to date has been 14.1. With a trap speed like that I should be hitting mid-low 13's easily. I have launch control on my car set at 4k. So if I pin the gas it builds around 1-2 psi before take off. If I drop the clutch I spin tires through first and get no traction. If I ride the clutch then it takes off like a slug. I need some advise so please help me out! Would investing in some traction bars be a good idea? Do they really work? Thanks in advance!

Solid motor mounts are a bitch IMHO. You'll feel every vibration on the planet with them.
Drag radials will work better than slicks. Invest in some Nittos.
How much boost are you getting? 1-2# seems kinda weaksauce for staging.
With the drag radials just spin that bitch up to 4000, side step it, and there ya go.
The goal is to get that 60' time down. If you're bogging out of the hole you won't be able to pick up a bunch of time/speed on the big end. Just a thought.

There are a few things to consider here before you proceed. You have to draw a line between your daily driver and your track car. What is bareable for me might be a living hell to you.
The stiffer your motor mounts are the better. The vibrations are a bitch but bareable if you ask me. This would be an issue if you were daily driving the car to some.
The traction bar is an awesome upgrade. It will extend your wheel base (if you do it the right way) and also keep the front suspension stiffer and will help eliminate wheel hop. This is beneficial on a street car or track car and not that big of a "cry baby" mod like the mounts.
I wouldn't worry about breaking axels; its a part of drag racing. Bring spares and be prepared to change an axle out. It takes a whole 20 minutes if that to change one? You could go with aftermarket axels but those break just as much too unless you buy a 4k setup which usually isn't feasable to most of us. Autozone has a lifetime warranty on their axles and are pretty damn strong for $125 and if you do break one, you'll get a new one for free. Now here is the big trick on not breaking axels; preloading. Stage your car, pull your ebrake up, bring your rpm to whatever the hell you launch at, slip the clutch just enough so it grabs, and when its time to take off, take the ebrake down and pop the clutch. This works almost EVERY time and well too. I've never broken an axle and most of my friends haven't either and some of them are runniny high 10s on stock axels. Its tricky to preload, but practice makes perfect and will save your wallet.
Side note: Do you have your time slip?
Good Luck

tons. i have f-r bars on my setup
Any ideas on how to fix wheel hop?
solid or atleast good urethane engine mounts, torque mount inserts or solid mounts, and traction bars.
if you preload on slicks, and leave right, your axles should last.
