Twincharge pressure mathematical formula

So Is This How Much U Got??

[QUOTE=Bill@usd;2862297]Makes sense if my calculation is correct

I search on the net, to find something from the subject


We will find out if ups would drop of my wastegate! dam brown! lol

So if I go out tonight and hit 15 psi then we will know that the math is right!

Bill i think you need to post the video you posted in the other thread showing your guage hitting 28-29 psi with only a 14.5 psi gate!

[Bill@usd]

this is the video

half throttle....for now

gasoline stoich is 14.7.

common misconception.

It's really more of a blower thats stacking air in the manifold which serves a similar purpose as compression but its really not compressing.

1 atmosphere doesnt equal one bar but they both mean the same thing if that makes any sense.

Atmosphere is actually mathematically correct but has been replaced by 1 bar for practical purposes when it comes to conversions.

it does make sense.

im being a goober like usual

[ralliartist]

wow, over my head now.

[sleeperbalt]

Just got mine done and it hits over 20 psi on a 8 psi wategate spring not bypassing the supercharger at all cuz I broke the nipple off my bypass!

Sound fu** sweet though.

Question. If you are running a TwinCharged setup what was the basis for using a 2.7" pulley?

I would think that you could put on a larger pulley and not deal with all the heat issues of the 2.7" pulley.

Any update Bill@usd?

That would be my guess. Run a bigger pulley and more power from the turbo since SC steals power to make power and creates alot of heat.

Any updates???

i think you'll get less efficiency if you run our S/C too low, 7psi might be alright, but its made for peak efficiency around 10psi. Also, are you just directing the turbo compressed air behind the supercharger?
