****. we still need to do yours.

 

Basically what turbobeserker said. You can forget about that without some serious mods. The guy also had rubber band tires on too so that helps ALOT. If you want to do what oyu are talking about you are oging to have to drop some serious coin.

Badz I wanna see the video of your badass truck.

Turbobeserker how did you come up with that calculation or a link to it seems useful.

 

Since atmospheric pressure is about 14.7psi, call it 15psi to make it easy. When you shove another 15psi into the engine you basically have another atmosphere in your engine. Atmospheric pressure is usually in psia. Boost is gauge pressure or psig. You take 15psia and add it to 15psig, you essentially get 30psia. Twice the normal atmosphere. That's how the "size" of the engine doubles. It allows the engine to burn as much fuel as a NA engine thats twice as big. And fuel makes power!

 

Though your right about that with a turbo, but a SC will not apply like that of a turbo induction. The SC takes power to make power.
Basically it would definately have to be 15psi coming from a turbo?
I've been confused on this though. If atmospheric pressure is at 14.7psi, then wouldn't an additional 14.7psi (from a turbo) equal to 0 psi.
I thought that the natural atmospheric pressure places a negative effect on psi. Though in general we don't look at it that way.
If I'm wrong then just forget about what I rumbled out here. I'm not a science major, but just relaying what I've heard. Oh, and I don't believe everything I hear either. That's why I'm asking. Or, I could be on the right track, but have the numbers wrong.
You guys tell me.

Ordered the kit monday. As soon as it and my new crank pulley/s arrive ( thanks Yellow4.8 and BADMOFO) it'll be getting the much needed fix. And on a side note, I'm looking to crank the boost up a bit more so anyone looking to sell some 60lb or 72lb injectors feel free to contact me.

 

Atmospheric pressure is 14.7psia -- that is close to what you are running at what (it is really close to your ambient pressure). So 14.7psia = 0psi of boost (with the negative numbers coming from the vacuum produced by the engine). Adding boost is added on to 0psi (or 14.7 psia), so 15psi of boost is 14.7 atmospheric + 15 psi of boost (or 29.7psia = 2 atmospheres, just like 29psi of boost is 3 atmospheres). Vanilla is dead on accurate.

This comes from the gas laws (specifically Boyles Law I think -- P1V1 = P2V2 -- so the volume at atmospheric = all of your cylinder volume, double the pressure, the volume is cut in half -- e.g. twice as much air fits in the cylinder to mix with twice as much fuel, hence, doubling the cubes -- 3x atmosphere = 1/3 the volume = tripling the cubes). This doesn't change based on turbo or s/c -- the s/c version just has some parasitic hp loss from spinning the blower.

 

Post robbers, the lot of ya

 

Well you are a little late on finding out that. You decided what you are going to do yet?

 

Well after reading these new posts, I wonder why I can't spin the tires off above 45...
Why don't you come up with a budget for your smoke show Pjstucn, then maybe we could help. Also are you still not willing to do a engine swap? how about a trans swap? the stock 60e is that strong you know.
