LS Style Throttle Body - EFI Stop/Restrictor Options?

rocketolds400 · 11-17-2021, 11:14 AM

Hello all.

I currently run brackets with my LS-based EFI combo, running 10.60's flat out. I'm looking to start running a local 10.90 index class with the goal of moving on to Super Street.

I have a factory LS3 intake with an aftermarket throttle body (cable operated) in the factory location.

Are there any throttle stops or restrictors out there for the factory style LS throttle body setup?

I'm sure I can kill the .3 with short shifting and weight, but just want to see all the options available!

Thanks!

I’m sure you could make an in line t-stop work. A little fabrication. You could always use ballast.

It can be surprisingly hard to slow a car down sometimes.

Weight is probably a sure thing.

If your ECU controls your timing you could use it to pull timing out early in the run.
