I am turning 15.2 at 90mph in the 1/4. and 9.5 at 75mph in the 1/8. with the setup I am running. Any suggestions on how to improve my ET? yes i know and bigger turbo and cam and porting and polishing. (I am doing this VERY SOON) but any suggestions that are within a tight budget?
-IHI turbo Manual BV 18psi, Cold air Induction with K&N, Street Slicks, back actuators are unhooked for better launch. and Walbro 255 FP (maybe) 60lbs in open throttle, 45-48 at idle. running barely on the rich side when at full throttle. bought car with 80k miles and not sure if the guy before us put it on. but from testing it, seems its deff aftermarket FP. (just ordered from stinger: FMIC, 3inch down piping exhaust, and short throw shifter) help?

What are back aculators?
What's the 60' time? What rpm are you launching at? Did you disconnect the front swaybar?

its the RIDE control on these cars. if you unhook them it keeps them from getting stiff at high rpms so my back end will drop down on launch. but the fronts are on still. and im launching at 4k and no its still on. should i unhook it? and 60' is 2.0

Oh, ride control actuators...got it.
By street slicks I assume you mean something like Mickey Thompson ET Streets or do you mean a drag radial?
The 60' is bad unless it's a regular street tire you are using. On any sort of slick, it should be in the 1.7 range when "right". Unhooking the front sway bar will help it transfer weight to the rear of the car. You'll also need to launch at a much higher rpm unless you have a 2-step to build boost on the line.
In the first 60', does it bog, spin, or something else?

its Toyo Proxes TQ (Drag Radial) 255 50 r16
And i thought it seemed kind of bad. but it does have trouble bogging at launch.
I have a video of my best run under track videos. im fixing it, where everyone can view it
And i want a 2step but havent put much thought into it. So launching at 5k should help? and unhooking the front sway bar?

You need to keep raising the RPM until you find the point where you no longer bog (but also don't spin clear through first gear). Yes on the sway bar.

I doubt you'll find that magic rpm with those tires and the weight of a TC.
