Fuel requirements. I have MMS Stage IIx heads(11.2:1 comp.) and 224 cam.
ported TB and all the other bolt-ons.
Car runs 100 oct. and TR6's
I am using stock injectors and stock fuel pump.
We have installed TNT's wet kit currently ready for 100hp jets.
I have an EGT gauge, and a fuel press. gauge is on the way.
Bottom line, is there going to be enough fuel or do I need to upgrade?
Suggestions on upgrades?
Thanks.

Re: Fuel requirements. Hey Hornmiester,
Personally I think you should put in a walbro 340 pump. About 125$.
Are you gonna mount the fuel pressure gauge inside? Did you get an isolater?
Your asking the stock pump to support about 500rwhp? You realize that right?
I think you should come over and pick up this 340 that I m looking at......(its in the box) and buy me another one.........
The bad part is putting it in..........drop the rear and exhuast etc......to pull the tank or cut the floor under the carpet.......I d opt for the second........about a 45 minute job that way...

Re: Fuel requirements. Well why didn't you say so on Sun. night?
What does that do give me more pressure?
If so isn't the injector going to hold back the excess fuel being delivered?

Re: Fuel requirements. It provides its own fuel? I know Im nit picky but it sounds like it makes it......lol
If your at wot.......there is a pressure drop across the fuel rail........then you add another pressure drop via the wet nos fuel supplement....and at some point.....the pump can t deliver enough......or keep up with demands.........and voila.....broken/melted pistons,valves etc........since the cost is so high if your wrong...its best to be dam sure unless your wanting that stroker sooner than later.
I don t know the stock pumps capabilties.....maybe we can test yours......I do know that a walbro 340 can support roughly 800 hp so its always a economical....cure that cures all doubt.

Re: Fuel requirements. Oh yea.....both of you make it sound like the fuel is coming from somewwhere else all together.........????most poeple pull fuel off there existing fuel rail/system......
Thats not required......I run a seperate system, myself.....so I was thinking maybe thats what you were both thinking.........
I run a seperate 1/2 gallon fuel tank in the engine compartment with a low pressure pump...and jet accordingly......that way I always run 116 in the nos fuel tank.......and if I squeeze on pump gas.....I pull more timing out or jet it down......yea right like I ever jet down... <img src="gr_grin.gif" border="0"> , I just cross my fingers and dont make a full pass....the race is ussually over in first gear..... <img src="gr_images/icons/cool.gif" border="0">
