alright i got my long tubes in today and hopefully by next week ill be on the dyno.. my mods are on a 2003 ford Boss... ram air hood converted to functional, 3.5in ram air intake, forged pistons/springs, pulleys, full exhaust, diablo programmer. 4:10 gears,1 step colder plugs, throttle body and spacer, 125 shot (dry) nitrous, boost-a-pump, and dyno tune.. without headers and exhaust and 4:10s, spacer it got 402 hp gettin upgraded tune and hopin ti get mid 400's.. also on my first dyno it was done with my balancer pulley shaking because the key hole shattered..but its new now

 

402... stock heads??? supercharged?

 

hes got a 125shot

 

yes Built they are stock heads just ported/polished. and that 402 is with my nitrous shot (125hp) it actually only gave me 121 hp and 155tq but i figured it was close enough to 125

 

Built is your truck completely done, and running properly if so do you have an est. quarter mile time that truck will run as well as hp/tq..

 

im going to the dyno saturday morning, but my 1/4 estimate is 13.00

 

so uve got 281hp? not bad.

 

is that the estimated for street tires or slicks.

watching your vids it looked a litte quicker or that it would be quicker with slicks

 

with slicks, i really have no idea, i hope its quicker, but who knows
