duragg Posted October 26, 2013 Share Posted October 26, 2013 I have been poked into running an Enduro next weekend and have LOTS of new considerations. Fuel flow being #1 and I never paid any attention before. Dumped tank and calibrated gauge in 1 gallon increments, great. But what should I wag for consumption figuring 7/10 to 9/10 driving? L28, triple DCOE 45s with 40 chokes at Sea Level. Wheel dyno hp in the 210 to 230 range. Any of you smart people have a WAG / HOUR? 5? 7? 10?

duragg Posted October 26, 2013 Author Share Posted October 26, 2013 If I use BSFC wags and figure 8/10 driving is average 50% of max horsepower, call it 120 average hp / hour... I'm screwed lol. 120 x .5 = 60 lbs /hr at 100LL 6lbs / gallon = extra fuel stop. Quote Link to comment Share on other sites More sharing options...
beermanpete Posted October 26, 2013 Share Posted October 26, 2013 We use about 6 gal/hour with our stock 240Z during time trial events. 1 Quote Link to comment Share on other sites More sharing options...
duragg Posted October 26, 2013 Author Share Posted October 26, 2013 We use about 6 gal/hour with our stock 240Z during time trial events. THank you that helps. Got to figure I will be at least 8 and possibly more. Quote Link to comment Share on other sites More sharing options...
clarkspeed Posted October 26, 2013 Share Posted October 26, 2013 With around 250hp good tune and running 10/10 I burn around 4 gal in 20 minutes. Quote Link to comment Share on other sites More sharing options...
johnc Posted October 27, 2013 Share Posted October 27, 2013 7 to 10 gph depending on state of tune. You will NOT be driving at 7/10s unless you want to get black flagged. Quote Link to comment Share on other sites More sharing options...

Tony D Posted November 2, 2013 Share Posted November 2, 2013 7 to 10 gph depending on state of tune. You will NOT be driving at 7/10s unless you want to get black flagged. LOL, yeah! LeMons up north was running the standard tank to a fuel pickup problem every two hours, and we never put more than 12 gallons back in it. That was with a bone stock L28 and four speed, so 6GPH. That seems to jibe with what most of the other guys were getting as well running Z's at later events. The next year we added a cam/3.9 gear and had considerably more power consumption went to 7.5 / HR... At the time I had calculated laps - distance to MPG, thinking it was somewhere in the 4.5 to 5 MPG Range if my recollection serves me properly. In enduros, a BIG fuel cell can be a friend indeed. An 18 gallon cell that could actually USE all 18 gallons would let us run 6 hours on ONE stop. Having a useable capacity of only 12 gallons made us stop TWICE. As I recall we lost 15 laps per fuel stop/driver change. Quote Link to comment Share on other sites More sharing options...
