Bone stock 5.3L ECSB track times, how'd I do?
 

I'd gotten a few 15.57's from the truck last year, but I'm possibly doing a story on minor bolt-ons for a magazine here shortly, so I wanted a set of slips with air conditions and such. Hit up Gainesville Raceway tonight for a TNT night.

Truck is a bone stock 2004 Sierra 5.3L ECSB 3.73 geared with a bed mat and soft tonneau cover (guessing 20-40 lbs extra weight)? When we dyno'd it (figures in sig), mph limiter was removed but no tuning otherwise (A/F was a 11.2) :barf:

Full tank of 87 octane, driven to the track and cooled for 20 minutes min before each run. Each run was done in OD and a 1400 rpm launch.

First pass at -176 DA:

.074 - Reaction time
2.296 - 60 foot (hint of spin)
6.465 - 330 foot
9.925 @ 71.63 - 1/8 mile and speed
12.910 - 1000 foot
15.488 @ 87.02 - 1/4 mile and speed

I was pleased! Pulled around and did run #2 35 minutes later:

-202 DA

.059 - Reaction time
2.273 - 60 foot
6.426 - 330 foot
9.875 @ 71.84 - 1/8 mile and speed
12.863 - 1000 foot
15.445 @ 86.92 - 1/4 mile and speed

Okay, getting better here!

Last pass 40 minutes later..

-320 DA

.050 - Reaction time
2.273 - 60 foot
6.425 - 330 foot
9.877 @ 71.81 - 1/8 mile and speed
12.868 - 1000 foot
15.454 @ 86.62 - 1/4 mile and speed

Just like last year, consistent and good bracket racer in a pinch!:)

I know this probably isn't even close to records of any kind, but just wanted some feedback??

I'm doing a catback and CAI shortly, then tuning with Formato afterwards and seeing what we get.

damn...keep it like it is and hustle some bracket races. hehe.

damn!
i hope i can run in those DA's when i come back :jest:
that's some pretty good times you got there for what it is.

Not bad at all man.When mine was stock i only got a 15.9
Of course i have the 3.42 gears compared to your 3.73 but still very nice runs man.

Very good for stock.
Mine ran a best of 15.08 with intake, exhaust and tuning in 78*
I'm 4x4 though, some extra DT loss is expected.

your last run was the exact same as mine time wise. i was pushin 87.xx mph tho. way to get the big bitch movin ;)

Those are great times for a stock EC.

Almost exactly what mine ran stock. 15.4x

my stock run was a 16.0 but i have 3.23 gears. i did pull 91 mph though
