Came across this when I was researching superchargers and intercoolers. The calculator allows you to set the current hp of your car, (either at the fly or the wheels) then you tell it the planned level of boost, what octane fuel you are planning on running, and if you are going to have an intercooler or not. It then tells you with the setup that you just input, whether or not it will work, and what you have to do to make it work. (Such as increase octane level, or retard ignition timing, etc.

Check it out here http://www.superchargersonline.com/hp_calculator.asp

I put our car in with 160 fly hp, put in 6 psi of boost (which is probably what TRD is going to be running) on 92 octane, and it says that it is a perfect combination. We would end up with about 225 fly hp and 180 wheel hp. If we add an intercooler on to the car, we can either increase the boost, or decrease the octane level. (Maybe if we add on an intercooler to the TRD setup we can still run 89 since gas prices are set to go above 3 dollars this summer) With a 3 core intercooler setup on our car, we could boost up to 12 psi no problem on 92 octane, and get 289 fly hp or 231 wheel hp. Have fun toying with this calculator, I sure am [/b]

 

That script just seems like a WHOLE LOT of guess work. Considering there are so many more variables than just boost, gas, and flywheel HP. I put in the specs for the scionspeed tC that's putting 300+ to the wheels and it said it's putting about 280 to the flywheel. I wouldn't really rely on that page.

 

if u use higher octane you get better hp??

 

This is at the top of that page...

"To be used for estimation purposes only - every engine is different and results will vary! This calculator is designed to offer a rough estimate of the amount of horsepower you can expect to gain by installing a supercharger on your vehicle as well as identify possible conflicts or inefficiencies in your setup. It is not nearly as accurate as actual dyno statistics. "

Its just suppost to give you a general idea. Anyways id rather have a calulator that underestimates the horsepower than overestimates it. there is a little section below it that tells you how the calculator works, there is also another calulator at the bottom of the page that ...

"If you're slightly more technically oriented, you can also download a full-featured performance calculator that will calculate:
• Horsepower & torque from 1/4 mile track results
• Supercharger impeller RPM for some popular supercharger head units
• Injector size necessary to support a set horsepower level
• Fuel pump size needed to support a particular injector size and duty cycle
• Effective injector size if running non-factory fuel pressure
• More

no, higher octane fuel has to do with how much boost you can run read this...

btw, does anyone know of a good site that has a bunch of different intercoolers that tells you their size, how many cores, and cfm rates.
