Big boost, tuning and trying to drive, roller coaster on wheels
Believe it or not, they may have already made one for the Evo. I talked to Ryan about Evo parts and said he had a front to back fuel system developed and ready for production. So maybe he has already CNC'd one.
I beleive the surge tank is illegal in my NHRA class so I will have to either figure something else out or move up into the very fast Modified class where I will hav zero chance to win
Here are the relevant rules from nhra:
1.4 FUEL SYSTEM
All fuel tank filler necks located inside trunk must have filler neck vented to outside of body. Vented caps prohibited. All batteries, fuel lines, fuel pumps or filler necks located inside trunk require complete bulkhead of at least .024-inch (.6 mm) steel or .032 (.8 mm) aluminium to isolate driver compartment from trunk. Fuel lines must be located outside driver compartment. Fuel tanks must be within the confines of the body. See General Regulations 1.5.
1.5 FUEL SYSTEMS
Location: All fuel tanks, lines, pumps, valves etc., must be outside of the driver's compartment and within the confines of the frame and/or steel body. Cool cans, in full-bodied cars, must be mounted a minimum of 6-inches (15.2 cm) forward of firewall. Fuel blocks must be located at least 6-inches (15.2 cm) forward of the flywheel/bellhousing area.
Tanks: When permitted by class regulations, fuel tanks located outside body and/or frame must be enclosed in a steel tube frame constructed of minimum 1 1/4-inch O.D. x .065-inch (31.8 x 1.65 mm) chrome moly or .118-inch (3.0 mm) mild steel tubing. All fuel tanks must be isolated from the driver's compartment by a firewall completely sealed to prevent any fuel from entering the driver's compartment. All fuel tanks must have a pressure cap and be vented outside of body. A positive-locking screw-on fuel tank cap is mandatory on all open-bodied cars. Insulated fuel tanks prohibited. When used, fuel cells must have a metal box protecting the part of the cell which is outside of body lines or trunk floor, excluding hose connection area in rear. All non-metallic fuel cells must be grounded to chassis.
Lines: All non-OEM fuel lines (including gauge and/or data recorder lines) must be metallic, steel-braided or FIA accepted "woven pushlock". A maximum of 12-inches (30.5 cm) total (front to rear) of non-metallic or non-steel braided is permitted for connection purposes only; individual injector nozzle and motorcycle fuel lines are excluded. Fuel lines (except steel braided lines) in flywheel/bellhousing area must be enclosed in a 16-inch (40.6 cm) length of steel tubing, 1/8-inch (3.2 mm) minimum wall thickness, securely mounted as a protection against fuel line rupture. It is mandatory that fuel lines passing supercharger drive belts be steel braided or be enclosed in protective steel tubing. Fuel lines must not be routed in the driveshaft tunnel.
Pumps/valves: Cars with non-OEM type mechanical fuel pumps must have a quick-action fuel shut off valve within easy reach of driver and located in main fuel line between the fuel tank and the carburetor and/or injectors. Fuel recirculation systems not part of normal fuel/pump system prohibited.
Fuel/air: Any method of artificially cooling or heating fuel prohibited (i.e.: cool cans, ice, freon, wet rags, etc.), except as noted in Class Requirements. Cool cans, wet towels, etc. are permitted in ET Handicap classes. Wet towels, rags, ice, etc. must be removed before vehicle leaves staging area. Ambient temperature air only; cooling or otherwise changing the conditions of the intake air prohibited.
Alternative Fuels: Containers for alternative fuels must be permanently labeled by the manufacturer as suitable for CNG or Propane. Tank must be vented outside of body. Alternative fuel systems must incorporate pressure relief valve meeting standards listed in NFPA 52. Alternative fuel systems must incorporate a manual shut off valve according to standards listed in NFPA52 for CNG vehicular systems. All hoses/lines used for alternative fuels must be permanently and distinctively marked by the manufacturer as to manufacturer name or trademark, service identifier and design pressure. Plastic, cast iron, galvanized, copper or aluminum pipe or hoses prohibited.
I had Culver at www.gtfabrications.com who made the surge tank, submit it to several types of racing sanctioning bodies and it was approved. I believe you will have no problems.
Give them a call, the do 700 hp drag dsm's no problem. You will need a swirl tank anyway if you want to roadrace that beast...

Hey Al - thanks for the props.
Sorry you didn't do as well as you wanted. I know you'll have it together for next month.
As for how Mike did - he got to the final 8 on Sat.
In the quarterfinal, he had the guy more than covered by the 1000' mark but misjudged his
braking through the traps and the other guy won by .02.
Did better on Sunday. Got down to the final 5, and was IMHO robbed out of getting into the semis.
They were giving bye runs (in odd car count situations) based on reaction time. Best got the bye.
Or at least they were - Mike rolled in with a .007 RT from the previous win, but he has to race
a auto G35 while the STI got the bye.
The STI had red lit on the previous round, but his opponent red lit first.
As they say, first is worse. I think it's a silly rule, especially in bracket racing.
Even if the slower car red lights, the other car should still have to run a clean run.
But the rules is the rules.
So the STI got the bye because his RT was best because it was a negative number; aint that bizatch ...
Anyway, he lost to the G35; again had him covered at the top end big time but again misjudged
the braking and broke out by .07.
He'll get better over time. I think he is starting to like this.
It was an interesting final 5 - one G35 and 4 AWD turbo cars, Mike, an STI, and 2 1G Eclipses.
Anyway, good to see you again.

Here is a souvenior of the last race.

Too bad we couldn;t hang out on Saturday night - it was a very long night of re-tuning for me to get ready for the race the next day !

"All fuel tanks must be isolated from the driver's compartment by a firewall completely sealed to prevent any fuel from entering the driver's compartment."GT0 - IF I do the serge tank route - I'll have to build a total firewall in the trunk - its a very god option but seems like a lot of work.
Obviously, its the best route to make the power the easiest way
Also if you rear the spefiic rules of the SRWD class I run in it sas ONLY stock fuel tanks. It remains to be seen how the NHRA techs will interpret that rule at the track if I have the stock tank and the surge tank ????

Good luck sorting it out.
I know of several dsm's running these tanks regularly without hassles. You could easily rivet a sheet of firewall material behind the seat where no one would see it to seal the trunk. Dual walbros will work too.
Then again, overbuilding the fuel system a little, might not be a bad idea with your monster. I am going to take my setup to the strip before I rebuild the tranny. It will be interesting to see whether they give me a hard time in tech.

Al, one way to do it is to use your walbro as a "feeder" pump for a higher flow pump mounted under the car. Personally I like the Bosch "044" pumps, they flow at about the same pressure as the Walbro but much more volume. Then run a -6 or -8 (stock is 5/16"... so its like -5) to the rail/regulator. That would give you the most fuel for the least cash and hassle. PM me if you need any of it - we stock those parts.

the two walboro idea has definately worked in the past al .you and me both know that. i am pretty sure your fuel gauge is not going to work. it didnt work last time we tried it.but the combination will give you enough fuel

I try to stay NHRA street RWD legal. While it may be harder to go as fast working within the confines of those rules, to me its more important to stay competative within the NHRA class

I wonder if this bosch would fit in the tank:
http://www.theoldone.com/components/fuelpumps/
This isn't for the evo but maybe it could be adapted. Also, wonder what the nhra rules say about mounting the pump outside the tank with a pickup line:
http://www.theoldone.com/articles/fuelpump/
You could go with a monster sx pump then...
Good luck
