upper port times

[ITS STOCK]

i have an 03 cobra steg 4 port, 2.76 upper, catback, sct maf, tune. spec3+ clutch and flywheel 26 spline

full weight 3900# with me in it sway bar on, spare in trunk big jack toolbox etc... 17" greg weld skinnys, with m&h biasply front runners, 16" v6 pony wheels out back with 26*9.5*16 hoosier qtp at 17 psi. 1/2 tank of gas

only got one run in, and seemed to bog, some guy sprayed some coolant all the way down the track.

70* outside strong corsswind 15-25?

4k launch
1.84 60 ft
7.70 1/8
92.73 1/8 mph
11.84 1/4
117.55 1/4 mph

question, what psi u guys run? ans what rpm to shift at?

and is it possilbe to get it down to a 11.50?

just looking for some tips as i am a track noob, thanks

next time out if you get some better launches and get the 60ft in the 1.6x range 11.50's will be yours, good 1st run, might want to lower the air pressure, just try different launch rpm's you will find what the car likes and get your time's with a few more passes

It should run alot faster than that, i ran those times upper only unported with 17" Nitto DRs. Get some more seat time, one run isnt good enough to tell how the car is performing, too many variables in play. Just for reference with your mod list plus a #4 lower i was running 11.0s @ 124 pretty consistently.

Seat time is the key, if you dont hit the track and make some passes with some regularity it will be harder to pull the best numbers out of the car.

Almost my exact times. :beer:

Ive only had the car down the track 3 times since the work, I ran 12PSI and 5K launches on new Etstreets and could only scratch a 1.76 as my best 60'.

Just like the boys say, more seat time is PRICELESS. :beer:

i ran 11.52 at 115mph, mods are close to yours, and my car is falling on it's face on the big end.. so you deff have alot more in your car
