WOW!!!! Less than a gallon of fuel, that's pretty lousy!!! I like power these Sirio 12's have, but I dont think it's worth the xtra $$$ you have to put out every month or so for a new rod, depending how often you race. I have a Novarossi RX 21 Kangaroo engine I ran in my Slide all last year. I have over 8 gallons of fuel through it and it still has excellent compression and it still gets stuck every so often when trying to start it. I guess you can't beat the quality of a Novarossi.
