To get in the 11's NA it took about 400 - 420 RWHP. To get to 11.5's NA what would it take? I know a drag pak "bogarts" would drop a couple tenths, but without doing that, just changing like cams, heads, headers, stuff like that. What would it take? 475 RWHP? 500 RWHP?

 

It may boil down to your weight. I run around 3975+ lbs and can run 11.50 all day. My rwhp is 450/413tq.

On top of that, you need the right combo for your power level. Your gear, converter, and tires must all work together for a low sixty foot.

 

Yea im not sure mine all works together well. 4.88's with 29.5x10.5 MT's, 3800 stall. Last time out wih this setup it ran 1.57 60ft 11.92@110. My slicks are heavy with the 15x10 steel wheels and i run 20x8.5 up front (78# each). Heres my weight on street tires and i think 1/4 tank of gas.

 

Was that weight with you in the truck ? Pretty dang light.

Mine was 4140 lbs with 1/3 tank of gas (street wheels\tires) and me inside too.

 

What does your torque curve look like from the dyno ?

The sixty foot your pulling is plenty good and your 11.3 run has great mph.

 

Yea that was without me. Its 4180 with me in it. I will have to go pull out the old slips and look at all the 60's i dont remember what it was on nitrous. My dyno sheet reads less than it is (gotta multiply by 1.1).

Heres the dyno sheet, doesnt show the whole curve though.

 

Not to jack the thread, but what was removed when you went to the scales, how much gas was in the tank?

 

I could probably get there with light weight wheels and skinnies up front but thats alot of work to swap all that down at the track and swap back to come home (1.5 hrs away)

 

I think it was 1/4 tank and the list is

Sway bar is removed, went from iron block to aluminum block, relocated battery under bed, removed tow hooks, empty washer bottle, battery tray, tray under intake system, jack and tools, spare and winch, plate winch bolts to, crossmember between bed and cab, evap system, built a custom fuel cell to go where spare was, swapped rear bumper for rollpan, center jump seat removed

Thats all i can think of right now, may be all of it i dont remember.

Heres a pic the day i went to the scales. I took this then drove 5 mins down the road and weighed

 

Well we are close to the same weight and sixty foot time so you will have to decide what you need to bring your torqe\hp way up, close to 450/400 and she should be near mid 11's.
