[QUOTE="tt335ci03cobra, post: 16070864, member: 68944"] Once boost is built, which takes half a second, a turbo voodoo will be at peak boost. No belt slip, no parasitic drag. 8psi in an engine that needs air down low is much better served via turbo than in a form that eats power via crank drag and possible belt slip. Also, most pd blower combos can’t rev high enough to keep up with the engine speed. Again, it’s just much easier to put a $5-6k blower on this car vs buy a $10k turbo kit and install it. Spooling twin 55’s with a voodoo isn’t hard at all. 4.6L modulars making 300tq we’re fitted with turbo kits centered on 50’s and then 57’s 10+ years ago. The cars with 50’s fully spooled quickly, but people wanted more powers. All of the powers. Some kits were centered around 61’s. I have a much peakier combo than a voodoo, and am running an out dated ecu. I have stage 3 ported gt500 heads and aggressive stage 3 turbo cams from MMR, as well as 9.3/1 compression, and 62’s in a T4 flavor. Manual transmission, very long 24”+ cold side. Read: very laggy combo on paper. Much more so than a voodoo (has milder cam profile, better low and medium airflow head design, much higher compression, only .1L smaller, etc etc than I have). My combo makes 10psi by 4000rpm. Just rolling onto my gas pedal wot in 3rd at 3000rpm, I have 5+ psi. and can jump from 50 to 115mph in a few seconds on pump gas with 15 year old parts. Turbo Voodoo’s are snappier than my old stuff, and can rev to 8000rpm. My combo is limited to 7000-7500rpm until I convert to a stand alone computer. I’m running scaled tables with 96% fuel trim on my 30psi tune. Incredibly inefficient. Here’s some media of low boost turbo gt350 action. Enjoy [MEDIA=youtube]BAoW_VfOwqs[/MEDIA] ^clearly states it had low end torque, spools fast etc etc [/QUOTE]
