How long is a gallon of 51/49 mix lasting you?

 

I start spraying at 5psi and 1 Gallon lasts me 1.5 months or so, granted if I am going to a meet or osmething I tend to get Boost happy, but shortest I have ever had to refill was like 2 weeks

550cc nozzle (largest)

 

Does anyone have an idea for a road race session/track/lapping what their consumption is with the 500cc nozzle?

 

hmm, maybe this would help, the stretch of the dragon that i drive each year is about 7 miles long. i went thru a .8 gallon of mix in 4 laps ROFL.

 

What size reservoir do you have and where is it located?

 

About the same here too.

 

Yea, using the 550cc nozzle as well, and during my last tune, i barely used 2" down on the 1gallon container.

 

the 550cc nozzle in theory should work out to 550ml/minute
but this must not be the case if it is lasting this long.

For example.
1 gallon is approx 4l
550ml/minute
= 7.3 minutes at full throttle, which I assume from what everyone is saying you are getting much more than this? Or are you just not full throttle very often?

I'm trying to run just water/meth as my IC and want to make sure have enough for 20 minute track sessions.

Thanks for the help!

 

well, what you could do, is look at the data from your 20 min session. then choose where you would start spraying. if its 5psi, then look at teh data and see how much time you spent above 5psi of boost. if it works out to less then 7.3 mins, then you should be fine.


your not always spraying is what im saying.

 

Unfortunately don't have any data as still building this car, but the data from our NA Super Touring IS300's shows TPS at 100% for at least 50% of a lap, and I would assume over 5 PSI boost for at least 70%.
This is what I was working from before and figured a 3 gallon would be necessary, but I'm wondering if the 550cc is actually flowing 550cc with the pressure the pump runs.
