Thank you!! I'm rebuilding my 6.1 Hemi in a Dodge Magnum. Been in a pickle on what route to go. I've read all these things on different boosts, but this right here is GOLD. My butt dyno feels that "torque dip" at 4000-4400 rpm, and that's when a Dyno made sense to me. lol Keep it coming, thank you.

Centrificalsupercharger + Weastgate? Hi Richard. Is it possible to put wastegate on a SC-system? For example you have pulleys so you got full boost at 3000rpm, and dont want to blow your engine at 6500rpm. Like in a trackcar, full throtllerespons and dont have go worry about "overboost".

Can definitely be done, although it does make the blower application less efficient since you're still spinning the blower at the same speed. But if you apply a wastegate and a boost controller to a centrifugal setup you can do some cool things. We use it to drop boost for cars that normally run high octane/e85/race fuel and want a safe pump gas map. It can also be used to limit power in lower gears for traction purposes.

The difference in the power vs. PSI numbers of the turbo and the blower is - the blower requires more psi to produce the power similar to the turbo( at lower boost) because of the parasitic drag of the blower.

Hey Richard, I'm sure on the engine dyno you go for the glory runs on most of these setups. And I think that's great for drag guys. But for us street guys that want to actually drive the car, and not have it so close to the edge that a tank of not so good premium melts it down. Coupled with typical 165-190° coolant temps, and safe timing with full street car accessories how much less on average would most of these setups make?

All I found are 5k+$ understandably. But I came across the 6.4 out of an 2018 6.4 out of a 2500 truck from what I read they are not the same as the SRT 392 made more for torque with 5.7 heads and different metals used pistons, heads for durability. But it's amazing deal for a 6.4 with low miles is it worth swapping with some power mods?. It's 3500$ for the truck motor can it be tuned up to 392 srt power?

Even my auto car doesnt see under 4500rpms other than launch and it goes through first quick. Roots and twin screw still have rising boost curves that dont make peak boost till farther out in the revs unless they are far undersized. Add in the extra parasitic losses driving the supercharger and the turbo car looks even better. This is all pretty strange anyways considering when are you driving wot off idle and or worried about the power right off idle? You never race at or just off idle lol.
