That 450 hp # was put out by me when the engine was first put together and I was thrilled with the way it ran. Since then I did chassis dyno it and came up with very respectable #'s. But not 450hp. The torgue when driving is a thrill. I do not rev it over 5000 rpm, so no real hp can be made without massive tq.
I do like to have a very respectable, streetable car and my recomendations to people reflect the same. For me to make 20+ PSI of boost on the brakes is not going to make a streetable car.
Don't care to argue about it either.
The main thing is, a turbo is probably a better choice over a supercharger on a inline 6 like the Chevy's. It is hard to mount the super charger and drive it from the crank.
A turbo is easier to package, easier on gas and can make more power.
I do have a question about the J&S safeguard knock sensor with regards to our six's. Where do you plan on mounting the sensor? There are not many attacking points that are good for this on these engines.
