ah and yet another question - with it being a roots blower, do you guys make significant more power with exhaust mods or head porting? the L guys dont. this being from the fact that a roots blower can only turn so many cfm.

Actually it is the MP112, not the M112 like the eaton on the Fords. The MP112 flows much better than a stock M112.

"blower rotors are twisted 60* to form a helix. The two counter rotating rotors have 3 lobes which intermesh during operation. This arrangement improves the adiabatic efficiency over tradistional Roots superchargers and gives instant throttle response."
so one difference is that they are twisted

My heavy *** extended cab beats up on stock lighnings all day at the track, drop the boost off to 2 lbs and they would be extra turd like. Stock lightnings around here run 14.8 - 14.1 best I have seen on a stock one. I ran a 14.3 in my truck with 2 mods:
Radix with stock 7 lb pulley
Muffler
Toolbox in back, spare tire, street tires, tailgate, full weight.
I dunno what I run now, been too busy lately to make it to the track. I have tried to race a couple lightnings on the street, but most of them tend to be cocky ********. One guy tried to rag on my trucks value. Funny how people tend to think that if you put a blower on an F150 it is all the sudden this excellent well built truck. It still has the cheasy dash with the 1.25" gap between the A-Pillars and the dash (just my opinion of course)

low blow? not much. i doubt that dude brings much to the table.
i think it is HILLAROUS that the LSx guys think stock Ls run so slow. i guess it is the same bias as the fbody guys hating on the 03-04 cobras but that is cool. this is a GM minded site afterall.
just fyi - this stock L in my sig with 2k miles on it SHOWROOM STOCK ran 13.9 @ 98 mph (1.98) in July FLORIDA heat. stock down to the shitty paper filter. but if you guys want to keep talking about mid 14 second Ls its your deal. i will run ya or bucks on this little 5.4L Triton lol.
i will say the inefficiencys of the stock Heaton Blowers on Ls arent the best, but hell, they ARE OEM afterall. what do you expect. pulley, chip, and airfilter costing less than 500 bucks will get ya over 400/500 at the rearwheels. gotta love the low rpm to get this tank moving.
as for centrifugal blower? yea right. you better come with a big blower, F1 or bigger to come close to the tq a roots/screw blower will. when dealing with 5K lbs raceweights, you better have 500 rwtq at 2500-3000 rpms and hold it to give your self a chance from embarrasing yourself.
a Lightning is just a F150 with a blower thrown on it?
tell me that when you have to slow down around corners when i stay in the gas. helps when i am trying to make that light around the corner
