truck setup before was running 28psi.

with new setup last night at 21psi got the following:

60ft 1.61 < left with only half the boost we normally do. have to dial boost build rate in the dfi yet.
330ft 4.425
1/8th 6.800
1/8mph 102.80
1/4 mi et 10.64
1/4 mph 127.58

this was a shakedown run. harry still has a lot of work to do in the timing and fuel tables.

any guess on what's gonna happen when we get high boost numbers. :)

>>>BTW tell me where to get that cam LOL<<

you will have to get with harry. this is harry's design.

the day after we went 10.70 i called harry up and said:

Me: harry guess its time we change the cam cuz we arent gonna go any faster with thtis 412.

harry: let me work up some numbers for you, call me back in 20 minutes.

me ok..... so i call him back in 15.

he gives me the specs.....

Me; how did you do that so fast? did you allready have it done?

harry: Actually i did it in my head.

so anyway, its harry's cam design. comp cams made it, it was ordered on a wednesday am and i had it on that same friday.

now what little i do know of it is its NOT A ROLLER CAM!

its hydraulic flat tappet <----- your ead this correctly

installation breakin requires lower valve spring pressure and 2500 rpm breakin for 30 minutes or run the risk of wiping lobe if you allow it to idle . so this meant remove inner springs, test all spring pressures at the same time, install everything, break it in. then take it all apart to put the inner springs backin. did it using leakdown tester and rotating crank for tdc on each cylinder. a fair amount of time and work.

you just have to remember to make sure you plug no 3 injector all the way in till you hear it click. :)
A bit of a funny story that i wont go into here... but you get the idea. :)

so if you want one of these your gonna have to get with harry as this is his
and i just dont know. :)

this was just the begginning of the new combination. i.e. 1st time to the track with this un-dialed in setup.

wont take much effort to figure out what we are trying to do.

Congrats Ed! If you could manage to shave 750 lbs off it,it would run 9's....Might be time to start training a 90 lb crackhead to drive it for you for rocks :wink:
