Turbo Horsepower - turbo kits, chassis, accessories

Now here is the nail in the coffin that was achieved at 27psi!! Now to be fair the turbo only motor was making a little less power (~50-100hp) at a lot of the same rpms as the turbo/SC combo. But if you raise the boost up to say 30-32 psi you would be making more power at all rpm points and have several 100 more hp on the top end. Or if you want to actually compare apples to apples and you raise the boost up to 44psi on the turbo you would be knocking on the 2000hp door (if the block holds up).

So 1188@ 44psi vs 1171@ 27psi that’s not even close, it’s blatantly obvious how inefficient the turbo/sc combo is

What size turbos on each car>?

Well looking at both sites the Hellion (the turbo/SC combo) kit uses twin T-4 61mm Turbonetics turbos, and the Turbo HP (turbo only car) uses twin Garret 57 mm T-3/T-4 hybrid turbos.
