when I swapped the twins for an sps62, I messed up the threads on one of my DDP4's, so I installed some 215's w/ thick washers... tons of idle haze, smokey, truck made 48psi, EGT's rarely saw 1200*. this was with the fuel rack resting on the stock front plug.

retorqued the studs up to 120lbs and installed the 4's today... anticipating a smoke show, I put ~1/8" pre-load on the AFC shaft and took the star wheel from full forward to contacting the spring. it'll bellow a black cloud if you romp it, but it's actually easier to control than it was before!

in 6th it's making 55psi w/ 50psi drive pressure, I didn't see the EGT's go over 1400*, and MY GOD does the turbo hit like a freight train now!

wish list: another 1000rpm and a 5sp

 

Thanks for the post Forrest!

makes me wanna go pawn stuff to get the DDP 4's in, Im sure they are a nice kick over 370s as well, What DVs u runnin on them?

Thats the setup I was looking at.. I was looking for reviews on the SPS62, I really like that unit and if it reacts like you say, I will have to ask Santa for another Visa...LOL..

 

I think Jeff said he picked up like 60hp over the 370's w/ his twin setup... I'm just running the 181 DV's

I just had a little scare! after all that, I pulled in to get fuel and saw oil dripping under the truck! started freaking out, and headed home... figured the worst I did was maybe blow the side cover seal. turns out I pinched the back valve cover gasket

 

40hp/120tq over 370's....to the ground! Congrats on getting some fuel back to her bud!!

 

thanks, it feels so much better! that oil leak had me sweatin' bullets, I'm supposed to drive to Oklahoma and then back down south of Houston after xmas!

 

Is that 40/120 with twins or with sps 62? and what exhaust housing?

 

that was with HX40/HT3B twins

 

got any idea what teh ddp4s would give me over the 435s?

 

DDP4's are rated as a 140HP Injector, as well as 435's. They would probably just run/drive a tad better and have a iddy-bitty less smoke... But thats just speculation... lol

 

yeah, proably not enough diff to warrant a change...

I've got a good client up in Magnolia!

 

Actually PDR 40 and PDR 3.5B more air then the standard 3B

 

Forest,

Did you get a deal on your DDP4's? I want a set but can't afford $899.

 

they were in the truck when I got it, but I've heard them selling for around $700, not sure where though.

 

What did you do with the lenny's stage 4 injectors?
