your 1/4 mile times is what I really want to know,
I don't have the PCM tuned yet, so I know that is really hurting me, but here is my best so far:

Temp: 79*
Relative Humidity: 100
Barometer: 30.49

RT: .764
60'2.102
330: 5.867
1/8: 8.818@83.03
1000:11.408
13.530@106.19

Does that look right, given the 60' time and running on the stock PCM program?? I am really curious. people that have similar mods or less are running way better than I am cutting similar 60' times, but the MPH are less than mine...
Let me add this run was made on 275/40 nitto DR's in the back and 275/40 BFG comp/ta in the front...all mounted on ZR1 rims, if that makes any differance..

 

I was running 13.0 consistently and a couple 12.9's but that was with 4:10's, that was before the cam/rr's & wp for what it's worth. I'm running it again soon and I am fairly certain it will be in the mid 12's now based on the way the car feels since the cam, feels much stronger overall now and pulls much harder. I did have the PCM tuned for the cam though, other mods in sig.

 

Ok let me get this right, you ran 13.0's consistantly with just 4.10's?? no other mods? the rest of the motor stock? before the LT4 cam install?? son of B@tch I can't drive worth a ****...

 

well the humidity isn't helping a whole lot. I would expect with those mods you should be easily in the 12's. BTW learn to launch it...2.1 60' on DR's is not so good

 

if I had a dime for everytime someone told me that...

 

No, I'm sorry, I meant with all my bolt on MODS but before the cam/rr/wp. I just meant I had similar bolt ons to you but I did have 4:10's. With all the bolt on's and stock gears I was running 13.2x's. I think you may need to have the PCM programmed and maybe your rockers are not adjusted properly. Although this cam and others do really like the 4:10's

 

Yeah, the car is screaming 4.10's, I am scheming this winter to do a moser 12 bolt swap with eaton posi, 4.10 gears, and 33 spline axles and 1350 yoke, pretty much the samething a member of the car club I am part of has.....I have adjusted the RR's accordingly, I get a little clickity clack, but nothing annoying...kinda frustrating because before the cam and LT's I was running 13.8's @ 100mph with a 2.0 60' on street tires...so you can probably see my frustration only able to gain .3 of a second...the car club I am part of MTFBA has a dyno session coming up, probably get the tuning done then...believe it or not my first trip to the track this year I ran a 14.2@103 and wow I was pretty upset about that, I changed the plugs out to NGKt55r's and did a TB bypass and ran the 13.5 a few weeks later...so I feel I am heading in the right direction just need some better WOT tuning..
