Hey guys
I went to the track again today and ran 1/4 mile best 14.9x sec
i had good traction and i've changed the fuel filter yesterday
and no check engine light
My truck is mostly stock It has only a knn filter with air box mod and boost bypass The truck has only 23550 miles on it
It was 85 deg
Please help
Whats wrong whith my truck???

 

it's in aruba?

 

tell us exactly what your timeslip says...

 

driver error? clogged inner cooler? track isn't prepped right? massive belt slippage?

could be a bunch of stuff

 

I would think living in the ABC islands, is like it is here in Florida, hot most of the time! My truck runs so much faster now that the temps are in the 50's.

In the summer with temps around 85 to 95, my truck runs like a slug!

Heres my time slip
60 ft 2.242
330 ft 6.328
et @ 594 ft 9.061
1/8 mile 9.668
1/8 mph 74.11
1/4 mile 14.965
1/4 mph 92.60

what do i have to do to find out if my intercooler is glogged?

 

pull your blower off. The intercooler is underneath it.
Your floormat wasn't hung under your gas pedal was it...j/k

 

You must have been spinning tires to get a 2.242 60'

Drive around the water box, heat the tires up dry.

Try launching at 1,000 RPM.

Intercooler clogged

Never heard of that one before...

let us know...

 

I've had my tires at 16 psi
i had a passenger with me.
she told me that at third speed the tires werespinning
but when i launched the tires werent spinning
and i dont think the intercooler is clogged because the liquid in the intercooler reserve tank were moving

 

Ok,

2.2 60 foot means you are spinning or not getting all the way on it!

92 mph in the 1/4 is WAY low... Are you holding the gas all the way through the 1/4?

Now you also say you have a boost bypass. Is it installed right? Maybe your bypassing the boost ALL the time?

 

Looks very similar to the times I was running when I first purchased my 03. Turns out the intercooler wasn't working. Crank up your L, let it run for about a minute then look at the intercooler de-gassing tank (it's on the passenger side next to the radiator). If you don't see any bubbling then your intercooler isn't working. I actually ran a 15.2 in the 1/4 and my 60ft was 2.2. After the the intercooler was fixed I ran a 14.1 and my 60ft was 2.0.....this was driving 2 hours to the track, no cool down, about 87 degrees and about 85% humidity. Huge difference! The master mechanic at the dealership told me that without the intercooler you loose about 65 HP. I don't know that to be a fact but that is what he said. Good luck!

p.s. If your intercooler is clogged, you probably won't see any bubbling in the de-gassing tank or it will be very little.

 

Don't forget to push the button for your Tranny Overdrive switch to off.

 

Yes i was holding the gas all the time
Yes i have boostbypass i have unplugged the wire

My intercooler de-gassing tank is bubbling

 

Keep practicing, sounds like everything is working OK.

 

yes i did that
