[the4wheeler]

dont have any hi pressure leeks anywere do you? or you think is it your FPR?
good to see some numbers tho!

[malibu795]

forget the lower two... is the same tune had to max the load cell out to get those numbers :rolleyes: had problem with the optical pick-up as well:(



leaks none that i know off.... got ~9,000 on the motor since we put it together3 months ago

[03 D-max]

i am guessing that 19xxx of rail pressure had alot to do with it

[TrentNell]

you better get that lift pump adam . what was your pw on that tune ?

[Turbotug]

How much boost were you able to make?

[the4wheeler]

oh yea i dident even think lift pump adam tho has a in bed tank and prity much gravity feed to the CP3.
still maybe liftpump in the fucher.:D

[malibu795]

33psi boost

3100Us

[Turbotug]

You're still running a stock charger, right?

[malibu795]

You're still running a stock charger, right?

yep stock charger, cp3 and no lift pump

[Stingpuller]

Now you have somewhere to start. If it was easy everyone would be doing it. Jeff

[malibu795]

this is true.. i was hoping for a higher point to start :rofl:

[Turbotug]

Winter fuel?

What wastegate mods?

Did you decrease comp ratio on the build?

[malibu795]

Winter fuel? most likely im in ohio

What wastegate mods? banks big head

Did you decrease comp ratio on the build?

i have no idea which way CR went..... probly down...

the .040 piston were machined down to wiegh the same as the .020 piston that was orginally balanced with...

safe bet CR is not 17.5:1

[Turbotug]

Well, if you indeed have winter fuel that should account for some of it. And begging the OE charger for 33psi..borrowed time..:D

How much boost do you see on the street? Similar to what you got in Cali before you left?

[malibu795]

i can hold 35psi in 5th wiht the new motor... it was 32psi with the old.. haven backed the gate off

[RPM Motorsports]

Is that a shift spike?

[malibu795]

these are 4th gear runs

http://c1.ac-images.myspacecdn.com/images02/9/l_b0daca3b2fbf4eb38a183b356117da50.jpg
the dip and spike is the 4-5 shift on this one
http://c4.ac-images.myspacecdn.com/images02/52/l_952f00d30f4c4085a65a9979ffe03c93.jpg

Is that a shift spike?

that what you refering to?

[RPM Motorsports]

Yeah, the one around 350ish.?

[malibu795]

iirc started in 5th rich(maddog) loaded it kick down to 4th then shifted back to 5th and he finished it out.

that was before i started messing with shift point.. currently 4-5 is 103mph with 35's

[JOHNBOY]

Drop your pulsewidth. I went past 500 a bunch of times with a 2850 shot. Pressure is your freind.;)

[JustinD]

Dyno jet? I was told they were no good for our trucks???, I dyno'd 460 and 851 in NOv on a Dynojet I was very dissapointed, I have twin lift pumps, and everything seems to be right on. Another guy, same year truck with no LP and a PPE hot +2 puts down 470 and 925????? I am going to try a Mustang (load cell) dyno!

[Big Block 88]

Numbers aren't bad it is a good startin point at least.

[slowlmm]

[QUOTE=JOHNBOY;168419]Drop your pulsewidth. I went past 500 a bunch of times with a 2850 shot. Pressure is your freind.;)[/QUOTE

x2 2850 and 28 psi boost netted me
503 and 1080 the more boost netted lower hp and higher tq on my truck with stock charger.3000us and 28 psi netted me 530 and 1080

[dmax687]

congrats!! x2 on the lift pump

[Samdweezel05]

Hey Adam, send me your tune and I'll take a look at it and seeif I can help.:rofl::angel:

no two truck are the same.

even more so when compareing LB7 to LLY, LBZ, LMM

X2 pressure is my friend..

all in all its not a bad starting point... really
given the tune really hasnt been changed since i put the new engine in. given the fact that the piston and bowls, compression and cam(06 lbz which is debatable weather it is different between that and a LB7 :rolleyes: ), compression ratio have all been changed to one extent or another

finally got my mpg today as well 410 to 26 gallons weighing 9,200lb ( 2,000# of sand in the back)= 15.7 mpg with alot of idle time and winter grade fuel.. this include the dyno pulls as well

what pressure are you guys running i've never tried over 25000-26000 psi how high can you go safely ? current tune is around 3100 usec @ 25000 psi holds about 21k-22k rail pressure through the 1/4 .

DynoJet 248C, SuperFlow, Mustang same truck same tune all over 500rwhp

no two truck are the same.

Get you pressure up you will like what you see. I did 507 on Dynojet with winter fuel. Stingpuller, Fingers, Minisub where there. On LB7s I never really had to change the fueling to get the power. The timing is what varied. But what do I know. :cool2:

Keeping the pressure over 21000 was the key for me.

[malibu795]

ill get it done dont worry ;):D

[the4wheeler]

just now got your phone message better late than never haha shoot me your questions hear in pm or on myspace
the ol phone is going down hill in a fast way

[duratothemax]

I wouldnt worry about it, duramax's are wierd on the dyno.

With the stock original engine and BD turbo, my 7680lb truck trapped 107mph easy in the 1/4 mile. I think it dyno'd like 450-460 or something silly like that.

[fast03]

Adam, is that the same tune you ran in Cali. ? track times from that tune?

[malibu795]

kinda..

fasted track time is in the sig 13.82@100.75 wieghing 7200lb that was in bakersfield june 07

The ET calculator is close 465hp@7200 pounds. Still not bad for stock turbo and 2wd.
