I am thinking of adding the Comptech Supercharger when they are available with the aftercooler this summer. Does anybody know how many miles one gets on a tank of gas now with either the vortech or comptech supercharge. Thanks

 

Same as stock. I got about 220-230 miles before the light comes on. When I drive in nothing but rush hour traffic it dips down to 200 before the light comes on.

BTW, Comptech has been "coming out with an intercooler/aftercooler option real soon" for about a year and a half.

 

Wes it doesnt seem to make sense to me that your mileage wasnt affected by the sc? Not that I know any better I just always assumed that it was going to increase.

Is your comparison keeping all other variables constant within reason? i.e similar driving style/wot etc

 

You have to consider that the motor only needs/gets more fuel under WOT and that it increases with boost. So, unless you're driving at WOT all the time at 4-6 PSI (between 7.5 and 9K) you really won't see that much extra fuel dissapearing. Even when I went to a 2-day track event at Texas World Speedway I was getting very similar fuel consumption to the NA S2000s. I have actually never seen a supercharged S2000 owner claiming the he's using up more fuel than before.

 

Thats interesting. As I said I have no experience with FI I just assumed that the consumtion would have to increase relative to the extra horses. Thanks for the prompt response

 

I would also think that during regular day driving (i.e. 2500-4500 RPM) the S/C isn't really dumping that much more fuel, or causing that much more of a load on the engine. Probably comes close to balancing out.

 

I've had my SC for a few weeks now - don't notice much difference in gas mileage. If there is a difference, it's probably cause I more now with the SC.

 

I think I get about 1 to 2 miles per gallon less. Before, I used to get 230-240 before the light would come on, now I get about 210-220 before the light comes on.
Then again, maybe I am just driving a little faster, not sure though. It's just been put back on the road, since last November.

 

with my vortech it's right arount 200 210 mile till the light so ti does use a bit more...

 

I have always heard the milage went up after FI on HWY milage, not sure about city.
