Noob because im not use to driving a built tranny/stalled 4l60e...

So i went to the track after breaking in the trans and stall, with my new nittos 555r's.

I thought these where suppouse to hook as everyone told me they would!!!
My times 16.1 et with a 2.1 60//// 15.7 et 2.3 60/// And the one pass i did some what hook, i let out thinking i was gona spin made 12.6 et 1.9 60 @ 106 I dont get it, does the stall make me loose Trap speed? When stock i was at 110 trap...

Im Pissed!!!
I know I wont see much Improvement as times get a lil faster than stock, and not hoping to see 11's but atleast a low 12.
What em i doing wrong? I have to admit, its a totally different car after the stall. So if you have a stall in your ride, please shime in.

I was way more consistent with stock trans and was able to pull a 2.0 sixty 12.9 Et @ 110

i could do a john force burn out with nittos once we put in the pt4000.......high 12s in the 1/4 with nitto.

next time at the track,switched to et streets & ran an 11.08@121 1.48 60'........

I checked the psi and they are at 38... Is that too much? But it shouldn't matter right!?

UGH!!! This is frustrating... It pulls nice from a 30 tho. lol

No way you're going to dead hook on the 555R.. You might if you add every suspension piece and a nice shock and spring combo. What pressure did you have them at? Did you do a sissy burnout? However, you should be able to consistentley have better 60s than a 2.1, at your power level.

Edit: 38 psi is waaaaay too much.

LASTOFTHEBREED02T/A

I was on 38 psi at the track... And as far as a burn out, the usual, around 6-8 seconds.

What psi should i run at the track?...

You are running them at 38psi? Try letting some air out if you are.

heymoej

iTrader: (67)

try around 16-18 psi..........

Doesnt that slow down the car? Im already running a shitty 106 trap with the stall.
I'll give it a try. What about launch rpm, even at 2k I spin through what it seems the whole 60.

38 in your fronts is ok but yes i agree try 16-18 for your rears.

heymoej

iTrader: (67)

60' is everything...................................yes, fill the fronts & lower the rears!

i have gone down to 12psi with the nittos & still did not hook,but did get squirelly on the big end.

38 on the back is dumb. drop it to 20 and each run after that drop it 1 more psi until you bog, then go up one. like said above, 38 on the front is ok, for less rolling resistance. i dont even run 38psi when i go on long road trips. high psi is not for drag tires, drag tires need less psi so they can wrinkle the side wall and grip the track.

106mph is low for that setup, even with the stall. Vig is a good quality converter, and shouldn't be costing you that much trap speed IMO. I used to run 106mph trap speeds with a lid/catback and a 3500 Yank - totally stock internals and full weight WS6.

I wonder if that new trans is a bit sloppy, or if your tune needs to be gone over again. I've noticed that sometimes with a new trans, shift points will need to be adjusted, maybe it's shifting too early and costing you some MPH.

Nittos may not be the best tires, but those 60's are horrid. There is no reason u shouldnt be able to do ~1.7 60's even with that nitto. You need to heat them up a lot and you need to run much less PSI in them. Also track prep can make a huge difference too. Try like 20psi, and do a burnout all the way into 2nd gear to get it nice and hot. Try launching by simply putting the hammer down on the 3rd yellow, no brake tq.

Some of your times dont even make any sense though... you did a 16.1 with a better 60 then when you ran 15.7? Are you letting off or something? I mean you must be as those times are very slow...

too much air...

I run a 107 trap and don't have near that mod list. What gear do you have in the rear? What rpm are you launching at?

LASTOFTHEBREED02T/A

iTrader: (15)

As I best remember 2k was rpm launch, the gears are stock 323's.

What the hell is costing me such a low trap speed?...

babbage1109

iTrader: (11)

I think the tire pressure is your enemy. You need to get it to stop spinning. Launch sounds right. But if you can't get it to hook that'd be my guess.

I gave a couple suggestions about this above:

Definately gonna want to take some air out of those Nittos. You have to do a good burnout and have them at like 16-18psi in order to hook. Even then though they can be a bitch to hook. Those tires IMO are meant for 12-14 second cars...

How are you launching the car? Brake pedal and revving the car up? Or just taking off from idle?
