might need a new torque converter with a higher RPM stall-speed?
And or tuning to allow the revs to be higher when holding the brake and the gas. A lot of times the ecu will not let you rev past a certain rpm when the brake is held all the way. It’ll rev up to X rpm and just kinda stumble and bog. The cruddy part is that the rpm at which it happens is lower than the stall speed. The wheels aren’t even close to starting to move.might need a new torque converter with a higher RPM stall-speed?
I think I launched at idle most all of the time my best reaction time was a 0.0979. Which I think to be pretty good. I may have to practice next time I go 🤷♂️And or tuning to allow the revs to be higher when holding the brake and the gas.

@KarsonS197 are you revving up the motor by holding the brake and gas or are you just launching off idle?
Do you think I haven enough HP to get down the 1/4 with what I have? Or more upgradesI think I launched at idle most all of the time my best reaction time was a 0.0979. Which I think to be pretty good. I may have to practice next time I go 🤷♂️
Seems like a good idea. @Bullitt95 what bolt one / other mods do you have.You need to launch with enough rpm to get you moving but not enough to where you just spin in one place.
Pay no attention to reaction time or to the “green light.” The clock doesn’t start running until you “break the beams.” One could sit there ten minutes after the light turned green and still get a 10 second 1/4 mile. Next time you go leave when you’re ready. I usually sit there a second after it turns green in attempts to get a good launch. Reaction time only matters if you’re racing someone else in a bracket racing type situation. It doesn’t equate into the overall time it takes to go down the drag strip. Maybe before you go if you can find a place to do it, practice “launching it.” You don’t have to get going real fast, but it’ll be loud. Hold the brake all the way down. Slowly give it gas until the wheels start to move. Remember that RPM. So now that you know at what rpm the wheels start to move rev it to just under that rpm while holding the brake, let off of the brake and floor it. If it spins in one place try again at a little lower rpm. It’s always going to spin with street tires. But you don’t want too much or too little.
@Bullitt95 says he launches at 2k and gets a 1.88 60’ and runs a 12.5 1/4 with bolt-ons.
Practice driving some more prior to ordering parts.
Yeah no burnout necessary with street tires really.and I think Bullitt95 is driving a manual, which makes it harder . . . so apparently it CAN be done without any more HP
the right burn-out can help a bit too . . . with street tires, as I understand it, you want to clean the tires but don't get them super hot because they will get greasy instead of sticky
For you, getting into the 12's would be easier than it is for me since you have an automatic that'll execute gear shifts quicker than I can. You already have 4.10 axle gears and if you add a 3000rpm stall converter plus tire/suspension upgrades to improve traction, you'll bring home a 12-sec timeslip.ive got an auto trans any way I would be able to launch at a higher Rpm?
What do you guys feel is the best drag radials to get?
I think if I were going to buy a dedicated set of racing tires a bias ply would be the way to go as far as bang for buck. Nothing is ever good at doing two things. A drag radial wouldn’t be a “good” street tire or a “good” drag tire. It’d be so so at both. Get a bias ply with the tallest sidewall that will fit.
98mm turbochargerWhat kind of mods do yall have that are running in the 12s on the 1/4 mile. My best time I ran was like a 13.48 or 13.49 last time I went. When I ran I had the following mods
Detroit rocker cams
Air raid cold air Intake
Magna flow exhaust
Throttle body space( lol)
And sct tuner
I have now have added
Pypes 1-5/8” long tube headers
And Catted x pipe
I have auto trans, what should I work on?
