im looking to run race gas in another fuel cell mounted in the tank to make more power for when im at the drag track. im going to mount it over the spare tire hole so this way the sump clears and the tank sits level. so let me know what you guys thing of the idea. i priced the parts i need at 350 bucks here are all the parts im looking to buy
Summit SUM-293205 - Summit® Aluminum Fuel Cells
Holley 12-920 - Holley In-Line Electric Fuel Pumps
Russell Performance 614018 - Russell AN to NPT Adapter Fittings
Earl's Performance 991003ERL - Earl's Performance Couplers
Professional Products 10232 - Professional Products NPT to Hose Adapter Fittings

 

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.

 

i dont want to have to run my tank dry and you never truly can run it dry

i would like to hear them. i get if some one crashes into me it will go boom

 

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

 

Ask me with perfect grammar and I'll tell you.

 

how are you going to control the return line?

 

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

I have a number in my head.

 

water injection > purple

 

lol yeah man some Water meth injection is the same price with alot better results and you can drive it everywhere witht the track power instead of being a ***** with what you have.

 

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.

 

i am going to have 2 maps on pump gas map one race gas map.

water and meth is a great thing besides the parts were it corrosive and kills you icv.

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.

the 99 miatas are returnless fuel system

i dont do any form of autocross only drag racing seeing how its only 20 buck for the day

 

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

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.

 

im sorry but i dont give 2 ***** for spec miata.


the Spec Miata (SM) class is intended to provide the opportunity to compete in low cost, production-based cars with limited modifications theres one of them

 

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.
