going to the track on thursday. track is about 200 ft elevation. my truck is a 04 ECSB 5.3 with 2600 miles.
I havent done anything to it yet, but I was going to do the TB-Bypass, custom intake tube between the MAF and the TB, and a ram-air setup on the stock box.

what do you think she will run stock and with the mods I listed??? Should I drop the tail gate too??? I have many years experience Drag Racing cars, just not trucks. used to have a 00 T/A lid/cutout A4 stock ran 12.8...

thanks

 

15.3 is my guess, and I don't drop the tailgate...but others may say othewise. Good luck!

 

is that with the mods that I listed or stock?

thanks for your input

 

I agree. 15.3 maybe 14.9 if you get great weather and have a decent built motor IE not a Fri or Monday motor.

The mods you listed really wont help much so the times shouldnt be much different.

 

dont drop the tailgate.... keep it up.. trust me... physics is a fucked up science.

 

14.9 on a stock 04 5.3 Ext. Cab Short Bed 3.73 truck w/ only ram air, tb-bypass?????? I wish

 

so keep the tail gate up? okay thanks Onyx
what is your prediction on my times? remember all stock motor ram air/ tb-bypass

 

Somehow missed the Ext.Cab part. In that case I say 15.6 with a great DA :p

You're gonna have about stock HP with those mods you listed. I'd bet the only gain you see from the ram air is lower IATs. And jury is out on the TB bypass, EGR mod etc etc. I've had a fast T/A too and tried all the lil free tricks

 

Would you make runs with it up and down and tell us what happens please?

 

OR take it off, for less weight = better ET's . You have a tonnau cover? keep the bed covered.
