Low HP and dont know why?????

[Bosshawg600]

So i dyned the truck again and it felt awesome but just lacked the HP. With all the Mods i have done to the truck ( well over 10K in the motor) I was getting out done wih stock turbo 12v trucks. I was only able to put down 387 HP and 887 tq. That was running 55 psi.

i would think with 20* timing, 71mm turbo, and a high flowing P-pump i would at least be over the 500 mark.

Any one have any clue why Im not laying down better numbers?

injs i bet, if there 370's out of a 12v i bet thats the issue

Yeah, that could do it...I'd find out for sure!

Injectors...then clutch

Can you post a dyno sheet?

Sucks when you've got a bunch of money sunk into an engine and then it sucks on the dyno.

if i can get my camera to work Ill get a pic posted. peak power was at 2500 RPM. Turbo lit pretty good, and we could smell the clutch slipping, but there wasnt much of a spike down to tell if that was the case. but i doubt it would cause me to lose too much HP.

Hope it didn't slip too bad:(

it didnt slip bad, didnt smell bad at all

Why would 370's be an issue ?

[Bosshawg600]

Spray pattern is off and doesnt shoot into the fuel bowl. But I dont know how bad that would limit my numbers. Its realy a mistery to me. I have gone over everything and cant figure out what is going on. most guys with a set up like mine are in the 600 range. Hate to say it but Im kinda getting sick of not being able to make pawer with this truck. Heck I can buy a stock CR and thow a box on it and make more power.

You've got the exact same problem I do. I've done everything. Swapped every sensor, injection pump (bout to swap in another one), injectors, turbo, fuel system, ecm, compression test, etc. Still can't figure it out. I know we got two different motors but maybe we can find somethign similar and help each other.

[Bosshawg600]

Im gonna bump the timing up to 24* and see if that wakes it up, then comes a DD clutch and injectors. If none of that does it, I be looking for a CR!

I got the fuel (lazer cuts, .120 Fuel lines, Fass, got the boost (71mm Running 55 psi), got the timing ( 20*) for well over 500 but its just not cutting it.

[bonesmx2000]

unless you have a 13mm pump why do you have .120 lines?????

[Bosshawg600]

the .120 line came on the truck. Dont realy feel like spemding the money to go to .093 lines.

[bonesmx2000]

they arent going to make you gain anything on the dyno jim fulmer noted that adding .120 lost hp everytime

[Bosshawg600]

Heres a vid of the dyno to show how it ran. Sounds good though, plus you can see the ecaust pipe somking after the runs!
