will you have a valve to switch from one gas tank to another or are you getting rid of the stock tank?

im going to have a check valve in each line so the fuel can only flow to the rail and not into the other tank

why not just run your tank dry on the way to the track and fill it up with your "race fuel" when you get there?

This is what all/most boosted track miatas do, in fact this is what most track cars do.

For a bunch of safety reasons that I won't even explain to you because you'll just ignore them anyway, you shouldn't do this.

Clearly, you no nothing. Spec miata drivers do it before races so they know exactly how much fuel is in their tanks.

How much extra power do you think "race gas" will make you?

I have a number in my head.

You are not going to get more power just by running "race gas" or "av gas".

You need to tune high octane fuel to get power. Unless you are going to switch between two different tunes you are asking for trouble.

im not sure how much i will make yet i have to get my new stuff on and tune it. im hoping to make an extra 30whp with race gas at the shop we have made we have evos that make 400 on pump and 435-450 on race. so with every thing tune i should see an extra 30whp.

This is your response in regard to Spec Miata? You really need to do your homework...

i have never seen or heard of any spec miata drag racing nor have i even payed any attention to spec miata. all i know about them is there mostly used for autocross. my car is a dd that gets used at the drag track once a month and i am not going to go out of my way to run my tank empty and have to waste the gas doing so. it is a lot easier to have a trunk mounted tank that i fill with race gas flip 2 switches one for the pump and one for my ecu to change the maps and boom done miata on race fuel. must be nice to run your tanks empty just to run race gas and have the money to fill them back up gas in CT is 3.00 for a gallon of 93 and it will be getting up to 4.00+ for a gallon this summer. so **** wasting the gas

Spec Miata : The Official Spec Miata Community

That took exactly 7 seconds. Either you're too lazy to type "spec miata" into a search window, or you don't know what the **** autocrossing is.

The point is they are track cars ********.


Autocross=cones

Road course wheel to wheel racing is what spec miata is.



ON TOPIC:

I don't know why you're worrying about a setup that will involve perfecting TWO tunes when you couldn't even get one tune right.

Also, how are you going to know when to switch back and forth between the two if you can't tell when the fuel line is full/empty of race gas during switches.


I see more bent rods in your future young Skywalker.

Damn, fellas! Ease up on the boy.

You will know when the race gas reaches the injectors by the smell of the exhaust gasses, I suppose.
Good for you for taking the initiative and experimenting with something new.

I would personally use the water/meth mix so that the benefits of the extra power/safety would always be available. Meth is safe unless you freebase it.
