back to the dyno... again, 1055rwhp kyle(1320video) is out of town so i did this vid on my own. 40meg>> http://www.neufamily.org/backtothedyno.wmv
just spent about 5 hours(23runs) at the dyno trying all kinds of things. the intention was to work on my fueling map and timing map. the video sums it up prety good but i will type it out for those that dont want to watch the vid.
we picked ~16psi for the boost level to work on.
at 16psi and 15deg of timing it hit 846rwhp.
tuned out the rich spots but couldn't get rid of the dip at 3000rpm wich is right where the meth kicks in and we got to 872rwhp.
bumped the timing up to 18deg, when i say 18 deg that is the peek timing at high rpms. at 5000rpm the timing is about 1.5deg lower than whatever i post up. at this level it hit 901rwhp.
bumpd the boost up to 19psi and hit 975rwhp.
bumped the boost up to 22psi and hit 1017rwhp.
took timing up to 19.5deg and got to 1040rwhp.
took timing up to 21deg and got to 1055rwhp.
it picked up 45rwhp at 2psi less boost so it seems like we were doing ok
on that last run it seemed to float the valves real bad at 6200rpm. it didn't do that on the other runs but it did the other night at 25psi. i didn't want to drop a valve or bang a piston so we called it day after that run.
next week we are going to hit up the track. i am going to keep all that timing in there and drop the boost to 16psi for my first run. we can bump it up from there if things look ok.
not really sure where to go from here. i could get better valve train and rev it on up. it has good internals. i am sure if i could carry good hp up into the upper 6000's it would pick up some ET by shifting later. the turbos could push a ton more boost but prety soon here it will start lifting the heads. how hard can you push these things before head gaskets become routien maintainance?
it also picked up some decent power down low with more timing. it is spooling slower but making more power so i stuck with it. overall it was a prety good day.

Very nice 
What/where is the dyno you went to? What track are you going to? Heading to Topeka? Don't forget the video. That truck should should run very strong 9's or 8's. Good luck.
-- By the way it was great to met you this last summer. Never really got to make any real boost runs. Minor problems. Next year is a different story

He definatly aint gonna get into the 8's. He has made nearly this power before and hes at like 10.005 or someting. Im not knockin him at ALL, save for the fact that he is insane. Im just sayin that 8's in a vechile that is a ton heavier then fbods with 1k hp prolly wont happen. GL Parish!

race weight is 5025lb's. i might be able to get it down to 4950 if i really try but thats about it. my 60' isn't that great and i cant apply fullpower till 65mph. i will be very happy if i can hit a high 9.
if i keep going with the truck i will be looking at geting it to hook down low and rev so it can hold the power up top. if i went 2wd and race seats i could drop close to 500lb's. or i might just try and sell it..

I would work on the suspension from here, try to get the most out of what you have before you dump for money in the motor and can't put it to the ground. Whatever you do, don't sell that truck, its the coolest setup on here man!
