who knows if the lightning lower crank pulley for increasing boost will fit newer ford trucks like my 07 f150 roush, some ppl say they do fit just want to verify if they will, can anyone help me out?
or if anyone knows where i can get one speacialy for roush trucks let me know where?
how much rwhp have u guys seen on a roush charged f150 runing 10pounds of boost?

 

Yes, the lightning overdrive pulleys will work with the Roush supercharger. Do a search for Metco, they make them. Troyer Performance has them. You're not going to get away with 10 lbs. of boost without a better fuel system. You're getting close to the design limits of this engine with that much boost, if you solve the fuel delivery issue.

 

so im going to need a better fuel pump once i reach 10lbs, in order for me to see the real results and the true power it should make with the 10lbs?
rite now im running stock 5lbs

 

You might want to look at the +2 pulley, but you're going to need some custom tuning. This setup is quite bit lighter than the Roush pulley system.

 

alright thanx alot for the help Windsor

 

i have the metco kit it fits and the box said for lightning and harley trucks, 5 lbs? i thought stock mine had between 6-7 now im at 8-9Lbs.

 

what rwhp are you making now?
how much did u pay for yours?
where did u purchase it?

 

troyer has them but you will pay for it, check ebay, i forget the amount i think it was around 200 or so:o. i put down 360rwhp but now i have new tunes a ported blower so probly closer to 400 somewhere

 

bluebeast06
what year of truck do u have and what blower do you got?
any other mods you got in the truck?

 

06 roush intercooled kit, troyer mail tunes, long tube headers hiflow cats, 2lb lower pulley, stage 4 ported blower with silencer holes filled on the blower.
i didnt dyno with the port or new tunes. it dose blow my mine that fx4 matt has the same stuff besides efans and coil packs and he makes well over 400rwhp, but he had his dyno tuned i belive. (ut 360- to over 400)60 ponys lost somewhere i dont know

 

how much was it to port your blower?

 

395 then you have shipping and all that fun stuff i think with the eaton they will charge 495 but since they qouted me on 395 they accually kept there word. steigmier is who i delt with very good customer service and what not while your there get those holes filled if your not comfortable doing it your self matt is in the process of before and after vid's

 

how much did the porting help you out?
what hp did u get from it?

 

If the aftermarket pulley will bolt up, I'm not sure, I believe you will have to ask for adapter ring that all of us 5.4 2V NA guys had to use when we used the 01-04 L lowers. The factory 99-00 L's had NA dampers, the 01-04 had a damper with a larger diameter flange which centers the lower pulley. METCO will have one!

 

i have not put it on a dyno yet i lost low end but picked up more up top.
