You guys who run on the track (i mean running hard, like racing), how much fuel do you use? looking for gallons per time. Also, let me know approx rear wheel hp.

thx, Joe

 

Stock tank, .7bar of boost, 464rwhp, about 100 miles to a tank

 

I'm not racing, but driving in the Black run group at DEs, I get about 4 mpg or ~80 miles with a stock tank. CIS, 1 bar and 350rwhp.

 

Mmmm, Turbos I get about 7.5 mpg with my puny 300 hp.

 

With my stock engine, I could barely go 45 mins on the track. Made it really difficult during the enduros (finally got a fuel cell this year). So I am typically around the 4mpg range, but I prefer to think of it as slightly better than a gallon a lap at the Glen . When you add it up, that's around 100 gallons for typical 3 day race event.

 

I'm somewhere between 4-4.5 mpg.

After 30 minutes of driving, it takes me about 8 gallons to fill the tank full again. I generally fill back up after every other session and it takes 3 5 gallon cans to fill it back up, after 2 sessions, and I generally put more than 5 gallons in each can - (approx 5.3 or so in each container).

3.6T 1bar boost CIS 380rwhp, i use the whole tank in 40mins during stock class enduro race.

 

My GT3 uses one quarter tank for a 20 minute session. Works out to about 90 miles per tank. My GT2 was (to my surprise) about the same. It had a 6700 RPM red line whereas the GT3 is 8200. Perhaps that's why.

 

6 gallons in 30 minutes --- 4.5 mpg

 

About $100 per day. Who pays attention to mileage?

 

I get approx 4.5 mpg in races

20 gals per hour at an average lap speed of 90mph

I know that this is off topic but do you guys actually manage to stay out, under track conditions, for 30 to 45 mins on the track without temperature sky rocketing.

 

Are you talking oil temperature?

If so, as an endurance race car, mine is setup to run 24 hour races.

Dual GT2 oil coolers, GT3RSR oil pump; and big 16 or 18 QT sump tank (cant remember exactly).

My Oil temps at the end of 1.5 hour race are at most 210....

Yes I was ... ok that explains it

 

That being said, my old 935 type car used to run much warmer - but I used to run 1.5 bar of boost.

That car ran 250-260.

I run mobil 15 50 and change it every race. Everything was specially coated including bearings in that engine.

On tear downs, the bearings still looked like new; which surprised me with those temps...

Although on that engine, I sued to fuel cool the engine the last 20% of the race to lower temps.
