times possible with 9 psi and a few other mods?

Supercharger aficiados have a very general rule of thumb, which isn't perfect, but is a ballpark figure. To gain 100 net horsepower, a supercharged engine must make 200 extra horsepower, and about 100 of it is used to drive the supercharger. It varies from supercharger to supercharger, but it is a general idea of how hard a 'charger must work to pump that much extra air into an engine.

During normal driving conditions, however, the charger doesn't make much, if any, boost, so gas mileage doesn't suffer too much.

As far as the 3800, it's a jewel of an engine. It responds well to increased air input, and it's very, very strong compared to most v6 engines. It has been on the 10 best engines list several times. It is dependable and predictable. I LOVE this engine. It's hard to argue with a wide, flat torque band, and 30mpg in a full size sedan.

it definately DOES NOT take 100 hp to turn the pully on a supercharger...


only on the top fuel dragsters does it take that much to turn the pully

[Darknight]

It varies, and centrifugal superchargers are more efficient, but still, you lose about half of the extra power you make just turning the charger. Positive displacement chargers take more energy generally than centrifugals.

You're actually quoting this website's example on parasitic lost from a SC. Realistically it doesn't take that much HP. If you could spin it by hand easily then not much is lost. If you spin a PD with a free hand really hard it will make a couple of rovolution and you can feel the air coming out.

But yeah your right about the V6 being one of the strongest engine out there. Even stronger than its big brother, LS1. Jan. 03 of Hemming's Rods & Performance did a 5 pg. article on it plus a 4 pg. article on it being swapped in cars. Awesome articles and its very detailed in history and performance.

Unless you are going to have it guzzle nitrous too i doubt it. Does anyone realize these cars we own are slugs. They are possible of 12's and under if you pay to have an LT1 LS1 or wanna get expensive LS6 dropped into it. I started with my car and 40 some thousand with a dream. Well its safe to say im selling it for a Mustang 5.0 that is already running 13.30's with stock intake heads and only 6lbs of boost. Sorry guys these car we own are soo hard to find parts for and to find anyone to machine anything. And they definitely cost too much to make fast.<hr></blockquote>


Thats pretty funny. My car runs neck and neck usually with a decnt running 5.0 (usually depends on driver) and a really well maintained one will pull me but not too baddly. And one that has been dogged.... well I win [img]smile.gif[/img] go ahead and throw a BS flag but I do well at the track in Kennedale Tx when I am not slinging drinks.

BESIDES if hes got 40k and a fbody why is he getting a mustang? there are a lot better ways to go fast with that kinda money.

actually a top fuel's SC takes more power to spin then a big block hemi makes stock, think about that.


anyway this pissing contest will be settled soon, we'll see what we can do with 9-10 psi in a 3.8.

Traction is the big issue, but mid to low 13s at least would be our initial objective.

Just because you can spin it with your hand and make at around 500 rpms under no load, doesn't mean that at 30,000 rpm inside the charger, under a 6-9 pound load, that it's anything similar at all. A human hand can produce from .5 to a full horsepower for a quick twist, actually. It would take well over 100 hands turning the pulley to equal the amount of force needed at WOT.

I didn't quote this website. If it uses similar number, it's entirely by chance. Big round numbers like 100 are easy to use.
