I can't believe it kept running with that little gas in the tank. I've never had a fill up above 11 gallons. I get 26-27mpg average.

 

Yeah but all them posts are usually... " Do S2000s get good gas milage when I floor it?"

Take your pick.

 

Sorry, my bad, vtec..., :-(

 

Average 260miles per tank with CTSC about 325whp

N/A I averaged 300miles.

These are typically with no bars left, but on fill up ends up being aprox 11.5 gal to refill.

Our tank is 13.5gal correct?

 

hmm i dunno, I always was under the impression it was 13.2 gallons.

Nice milage on CTSC... I take it your not full throttle too often?

 

I agree with that.

 

I commute a lot usually get near 28mpg or 26 mpg with a couple of VTEC sprints

 

Friday I did a trip up the turnpike (OKC <> Tulsa). I filled up the day before with one trip home <> work. 'Filled up' after the trip, 321.6 miles, took 9.379 gallons = 34.3 mpg (450 miles on a tank??). My running average is 25.7 mpg. Of course the next tank will probably show poor mileage as I fill the tank 'more' completely.

 

Yes I think your right it is 13.2 now that you mention it.

The Centrifugal CTSC is a great way to get allot of power without allot of gas usage. 260 per tank is with lots of full throttle pulls, as many as I have room for, its too much fun. Thats why i got aprox 40 less miles per tank when I was N/A. 300 N/A was lots of hard running as well. The thing with a SC is it uses no more fuel when driving normal then an N/A car and obviously thats the majority of the driving on the street. A N/A car driving with the AC on would see less mileage on a tank then a SC car without, and certainly the N/A car would feel much more sluggish.

If you spin the CTSC pulley on the car when there is no belt attached you will notice there is no resistance, its almost like spinning a wheel on a skate board, therefor there is no power loss or drag on the engine to turn it when just cruising around, there is however constant forced air flow to the engine even though not under enough for boost register. I experienced under normal driving more engine response and less heat soak overall. In my experience I believe that driving with an CTSC if never brought into boost could likely see marginal better fuel mileage. This however is only a factor with conservative boost levels wile maintaining the use of factory fuel ejectors, I am pushing that threshold at 8 psi. Running 650cc at 10psi for example isn't going to work for fuel mileage, but 7psi or under with stock ejectors is likely, but with no boost usage as stated.
