Help with 60'

[lvmustanggt]

I got 02 mustang gt with on 3 performance turbo kit . Master power T70 turbo at 8.5-9 psi .

Here my suspension
Upr k-memeber kit with coil over 14-175 springs up front and KYB ADJ struts (1-4) setting, and at track I put 1 the softest
Back BBK LCA , upr rear coilover 10-150# springs with lakewood 50/50 shocks.
I use stock gt rims for drag racing and got M/T Street Drag Radial at 16 psi. ( Not much thread left )

With stock suspension I used to run 1.81 60' with N/A 297rwhp and now with about 430rwqh I cannot do #### even with suspension. I need your help

I went to the track twice after I got my turbo up and running but best to date is 12.4 at 113mph and 1.85 60'.

I know my 3.73 gear are hurting me and going to get 3.27 gear asap funds get available. Going to also get WOT BOX asap funds available to help with 2 step and no lift feature as every time I shift I need to make boost back up. No lift feature will keep full boost when I shift .

Any suggestion to get me in 11 high sec please do so. Thanks in adavance

Are you blowing the tires or bogging? If you are spinning how much are you heating them up? The pressure seems fine although I've had mine at 14lbs and hooked pretty good...not that my HP is anywhere near yours.

First, 150lb rear spring is a little too heavy, I would probably use a 130 lb spring in the rear. Do you have double adjustable upper control arms? If not you MUST have them to properly set your pinion angle, which brings up another question. What type of suspension bushings do you have in your lca's, rear housing and uppers? Lastly don't change your gears 3.73's are fine for what you're doing. What size tire are you running? 26" or 28". The suspension described above has worked great for us in the past netting us a 1.36 60ft in my brother in laws 04 cobra with a solid axle. If you have any questions about how to set your pinion angle or what to set it to let me know I'm happy to help.

I do real nice burnout , it's about 7-9 sec. 1st gear and 2 gear I am all over the place, they don't prep track like they used to .

Upr gave me 175lb springs for rear and I just got 150lb rear springs after I told them it was too stiff. I got this 150lb springs just last friday the same day I went to the track and did 1.85 60' . Before when I had 175lb springs I was doing 1.9-2.0 60' .Stock UCA , BBK LCA, suspension bushing on my lca's are poly that came with it. I am using 275/40/17 mt et street . I really don't have clue how to set up pinion angle.

My car is DD so I think 130lb might be too soft ? If not I will start saving for 130lb springs.

Well first and foremost you need to check your pinion angle. It should be -3* for your application. You will need double adjustable control arms to prperly adjust your pinion angle.
Here are directions for adjusting your pinion angle:

You could try some slicks instead of the DRs

New rules from our track is no full slicks on friday night race as they want it to be street cars. only Dr ok

NO, you need double adjustable upper control arms! Non adjustable lca's would be fine.
Ps. Slicks are a band aid! There is no reason a drag radial will not work other than a porly set up suspension. most people are so fast to blame the track, when really it's there suspension.
