Got a few videos of my truck today. I swapped some lazer cut delivery valves into my truck last night just to try them out. The butt dyno says i gained a decent bit of power and it smokes quite a bit more. With the 191s i could clear the smoke up to a good haze but with these it just never clears up. I knew my temps were gonna be hotter but actually theyre not as bad as i thought they were going to be. The temps arent much worse than my 191s were. I definitely wouldnt want to haul much with this combo but its very driveable on the street. If i want to i can take off without it smoking hardly at all, but the power sure is there if i "need" it

that thing looks and sounds sweet

have you done any AFC mods (washers, grinding, etc.)?

nice vids, nice truck, sweet sound, nice place!

how hot does it run? i havnt put my truck back together yet but i have a sps62 and ddp4's to put in and im curious. I have 181DV's right now but was considering getting laser cuts. Also what kind of power gains do you think you got over the 191's

Thanks!

I would say 50hp over 191's with enough air...but with DDP4's and Laser Cuts you'll need a B2 at least underneath that SPS62 to keep the temps sane!

I'm guessing you guys haven't modded the AFC? my truck w/ DDP4's will hit 1600* at 50psi through a ported head w/ my sps62, and that's w/ 181 DV's.

I can't imagine what bigger DV's would do (nor am I going to find out! LOL!)

god loveit! how much did that goerend tranny/flex plate, set ya back? if ya don't mind me askin.

Captain

I have diffrent AFC springs thats it. I have a stock head but the turbo is set to dump at 40psi. That sure does seem hot! I was hopeing to avoid twins.. well see how long that lasts.

Videos are awsome.

Cummins Freak

yeah wiht all that fuel before the Lazer cuts how can you even keep EGT's in check what so ever now with only a sps62???? also how hot does that thing run under load or does you pyro just keep spinning

Captain

No idea. its all brand new and im still installing it. I was told a sps64 wouldnt really cool it any better and wouldnt be as streetable. and a 66 just isnt streetable at all.

EGTs can definitely become an issue. Youve just got to watch the gauge and adjust it accordingly. Sure i can bury the pyro with the best of them, but if you drive it sanely its completely fine. These motors can take extreme amounts of heat as long as its not for extended periods of time. If it breaks just build it back bigger and stronger

Forrest Nearing

I used to bury the needle on my old truck... when the head had surface cracks all in the face, I vowed to keep temps sane on the next one I built... I don't consider 1600 insane, but just pegging the needle doesn't turn me on anymore

next step for me is water/meth, if the needle stops moving anywhere below 1500, I'll be happy (and will probably throw more fuel at it! LOL!)
