I have a Vortech Supercharger and was wonder what is everyone RPM ranges with a Supercharger? and Gas mileage

60 @ 3500
75 @ 4500

Is this normal? I get around 26MPG going 75mph straight highway.

 

lol really? A sc is not going to change your rpms at a given speed.

 

You're question is a little too general. Some people runs a different FD, so that would affect their RPM vs Speed, some people run more boost, bigger injectors, and tuned, so that would affect the MPG.

I'm at 11psi Kpro tuned on ID1000cc with 4.3 FD and AP2 tranny.

75mph @ 4400rpm

Straight highway, 26-27 mpg. Mixed city and highway, 20-21 mpg.

 

Why would a supercharger change your rpm's? Gears do that...

 

im assuming you bought ur car sced?

 

yea, i did. as you can see im still a noob to FI. Thanks for clearing it up for me. Much more to learn...

 

he is asking what is your MPG with the supercharger at the following speed ranges

MPG @ 60mph @ 3500rpms

MPG @ 75mph @ 4500rpms

 

If you read the post it says what is the rpm 's at those mph and also what mpg's people are getting..

 

I get about 240miles per tank 91 octane when the light comes on from a full take.

The first half a tank i get the most... and the second half is gone in a blink of an eye!

LOL
