Wait a minute......did they route the belt correctly? I think the blower is turning the wrong way! You have 18 in. Of vacuum, not boost! J/j with ya bro...I'm hoping you get it figured out. Still hadn't heard what gear and rpm your going through the traps at...

I am in SoCal so if you need any help/advice I am a jump, skip and a hop away.

We need to see that dyno graph to further help you. It will tell us the type(DynoJet, Mustang, DynoDynamics etc.) of dyno used and what correction factor they used.

I will get the graph and post it.
THANKS for all the input !

Lol, could be, with those times.

Honestly I don't know what gear I was in at the traps, should have paid more attention. (I will next time)

It does seem to bog down abit from 1st-2nd, other shift points seem smoother with down bogging.

I definately will., Thanks,

OP's gaining roughly 24-25mph from the 1/8 to the 1/4, IMO that seems about right, first part of the track is where the problem lies.

[JoeyB]

Beers on me, when you guys get me into the low 11's.

I pretty sure I'm heading to NorCal on the 27th for the drags.
Will keep track of everything each run and report back.

Still waiting on the shop to get back to me regarding this issue. I'll post their reply.

THANKS AGAIN !!

Here's a good DA calculator for you.

Any chance you logged a run or two? That would give some good clues as to if it's pulling timing, seeing knock, etc and will tell you exactly when the trans is shifting. That way you'll know exactly and not guess at the tach. It will also let you know what direction to go when you make adjustments. Good luck!

Damn, I need to go back east and get my car upgraded there. Nice times !!
(The first Camaro I owned was in NJ and I towed it out West)
How do I "log a run or two" ?
Thanks

LOL, gotta tell you I traded my Z06 (6speed) for this Camaro and with these knucklehead drivers out here, I love the auto/manuel.
I just keep it Sport mode 100% of the time.

I have EFI Live and HP Tuners so next time we meet at the track I can log your runs.

I the meantime get that dyno sheet from the shop. I am sure they can email it to you.

I am not too sure of low 11's based on you trap speed and previous times but mid 11's should be a snap. If we can figuer out what is holding you back then 600rwhp should be low 11's though.

I went 10.9 with 640rwhp but the tranny was not too happy about it. Circle D just rebuilt it and as soon as it comes in I will give it another shot.

BTW, auto's are the bomb! I haven't seen a stick at the track faster than the autos. I know they are out there but none has stepped up yet.

Thanks,

Density Altitude for the 3pm run was 3462ft.


DA for the 8pm run was 2370ft.

Best run corrects to 11.777 at 118.219.

Best run corrected RWHP is about 550.

I'm guessing track and track prep is the problem. Some tracks are just always 2-3 tenths slower. I've raced in California at Carlsbad and it was just plain slow.
