well i was going to wait on ATS to come out with the MST turbo but they are taking way to long, just wanted some imput on if i had enough fuel to spinn the SPS66 as a daily driver. i no i have a pretty heavily BOMBED truck but the ats turbo i have right now is way undersized for the injectors i have. what do you guys think would be my best bet.

I ran a SPS66 for a couple weeks. With my fueling mods it was somewhat laggy to 10 psi, but after the it lit like a rocket. The 66 has poor street manners and towing is out. But the new Silver Bullet is supose to cool like a 66 w/o all the bad manners.

well like i said i am lookin for something that is an every day driver. this is my personall daily driver and i RARELY tow anything. its just with my mods i have, my smoke level barely clears any at all with the turbo i got right now and just crusing at 65 the pre turbo pyro is at like 950 to 1000 just cruising. with boxes off it will hit 1250 with just injectors. everything turned on, it pegs my pyro at 1500 quick.

I was talking to a Tdr member at spring fling who has the silver bullet with mach 5's, tst, and a timing box good for 550+ He said he'd build 5-7 lbs just cruising down the highway. But the cost of that thing is almost double that of just a ps62 =\

On second thought you should just send your turbo to II or HTT and have them mod it for you.

With my sp 66 cruising down the highway at 70 to 75 i am at 4 or 5psi of boost and about 750 EGT temp.

inline6power

is your gauge post turbo or pre turbo.

CTD2001

my gauge is pre turbo, in the manifold. I am going to be purchasing some Mach 6 injectors, from the people that i have asked and have talked to, this setup should net me somewhere over 500hp and over 1000ftlbs torque

inline6power

man thats way cooler than what i run, i mean just say i was crusing at 50 with very very very light foot, its still at 900 to 950. way to hot. i am pretty close to the 500 mark i think, never had it on the dyno but with spray i hope to be upper 500s to mabey close 600.

CTD2001

yeah, that is pretty hot, mine will get to about 900 going up a hill at 75mph and about 8-10psi of boost, but on a flat surface it is like i said before

inline6power

what is it at WOT. with jus my injectors it will barely touch 1200. with the boxes on it will peg my pyro gauge at 1500 quick.

Ph4tty

My money says you'll hit 500 with the M6's. In fact you'll blow 500 out of the water

Have you tried unplugging the VA? You're running comp + va = 2 timing boxes
BTW I think you'd be around 500 with comp, 165 hp injectors, and the HRVP- see my sig.

inline6power

not sure how to unplug the VA box. its the one thats wired into my injection pump harness. it was that way when i bought the truck. do you think that the VA box could be hurting me in performance. i no your not suppost to stack 2 timing boxes but my truck runs pretty good. if you are telling me that i could run better if i unplug my VA box then consider it done

inline6power

so do you think the va box is hurtin my hp#s or no?
