Default tips, tricks for a better ET?

Pretty much tapped out my funds for this season with the blower. About to order some lower control arms and light weight radiator support brackets for the front end (shave some weight). I already took out the Shaker 1000 subs/amps (60 lbs. reduction?) and will take out the spare tire/jack at the track. The 4.10s and street tires are killing my launch! Not to mention the shipping charges for tires/rims way up north (AK), $150+?? damn).

Any other tricks to get a better ET? Lower the pressure on the rear tires, up the fronts?
Leave at a lower rpm? (I leave right at 2800, power breaking. "Cut outs" are generous.. 2k rpm without)

Best of 12.7@106mph, 12.8@105mph average, 13.0 heat-soaked and ready to go home!

I am trying not to go sideways for the first half of the track. I do a mini burn out (no way around it, they spray the entire front section of the track) before every run.

A good set of DRs will get you more gain than anything else I could think of.

A good rule of thumb is for every .10 you drop your 60' your ET drops .20.

So if you 60' 2.2 and you drop it down to 1.80 you could shave off .6-.8 depending on the track and such.

It's not a hard stead fast rule but when it is pretty accurate.

A dude at the shop I used to work at told me that him and his buddy's used to buy used tires and burn the threads off them doing burn outs until they were bald (slicks?),then lowering the pressure and head to the track. They worked pretty good until one of them burst a tire and hit the wall, almost hitting the flagger for the staging lanes.

Looks like I have to save up for some MT ET streets, I think "old man tate" is losing it

lulz

Tires are a no brainer at your increased power level. Until the tires go on just try leaving the line like your pulling away from a traffic light Quickly. If all your doing is spinning you'll be better off leaving soft. At least your moving.

Ditto.. I haven't tried that yet. I either really "*****-footed" it off the line, which results in a 13.1 at best or been too brave and spun out and red-lined it where I stood and headed straight for the wall when it shifted lol The funny thing is, when I did that, stopped completely, then rolled into throttle, I still managed a 13.8 with is still better than stock lol.

The 4.10s, auto, stock torque converter and centri blower makes for a weird combo. When I am out of boost, it's very tame, but it all kicks in instantly and hard to predict at times... kinda like volume ****, switching from "min" to "max" very quickly. With the delete plates in, there is no pause in the rpm, and it just takes off. When it gets to 4th gear and 3500 rpm, the power just drops, which explains the low traps (105/107)

Tires/rims are my no.#1 priority right now.. in my mind I am thinking the larger (305/315s?) and softer the better, maybe I am wrong (??)

I seen AMs rear seat delete and it does look pretty awesome.. my girl has a ton of little ones (siblings) that tag along at times, but this mod is a great deterrent lol

Next year, I am pretty sure I will keep the Vortech and get a 3k stall Percision industries torque converter, LCAs, Spydershafts and some fat ol' MT ET streets, skinnies up front..

if that don't get me into the low 12s.. I quit. Seriously.

Save your $$$ and get a 4k stall and some tires.

Seriously though, I hear your question. I've had a supercharged (centri) geared auto before. It had a few more things done than you, but this technique should still apply. All I did was roll into it from idle, thats it. Don't try power braking or getting the RPM up on launch. Just press the throttle to the floor in a nice smooth manner. The track is most likely plenty sticky. If you can hear your tires rolling across it, its sticky. There's traction there, just don't get greedy. I pulled 1.7 60s with my procharged auto on street tires, so can you.

Btw, what does your elevation look like out there?

Obvious fact is obvious.


but srsly srs. Get some meth, or an intercooler. having to cool down your car after every run just to make power is teh gay.
