996TT K24/18G fuel Support - exhaust
hello speeders ,
one of my friends is running k24/18g with stock fuel system ,he is ran out of fuel if we get more than 1bar of boost ,
i would like to get bigger injectors and UPGRADED FR !!
so what do you suggest ? and whas your recommendations ?? he just looking to get 600whp only , it is just safe to run enough fuel !
something else what is the best exhaust to fit the k24 and has aggrasive sound in WOT ?
thanks in advance ,
Yousef

With a 5 bar fpr I was told that you are good to 1.1 boost on 18g's at 1.2 your running out of fuel then. I wouldn't run more than .9 on a stock fuel system. If your trying to achieve 600 whp your not going to do it with a 5 bar fpr. But for a quick fix in the meantime get a 5 bar in there ASAP! I would go with 72lb Bosch ev14 fuel injectors with the stock 3.8 fpr. You'll probably need a second or larger fuel pump to get to the 600 whp range. Tell your friend to talk to his tuner and he will suggest the best option for him. A setup like johnspeeds should get you there with a catless exhaust and 100+ octane gas. I almost have the same setup minus the extra fuel pump and other odds and ends johns got. I think he's near or above 600whp on pump gas. Good luck!

Now my next thing, I am going to try on the dyno,to see if it helps,A 74mm throttle body and a Protomotive modified stock Y-pipe that matches up to the TB...

What boost/HP levels did you run out of fuel at? I'm worried I'll experience the same fate here soon.

Hey,Do you mean when I had to go to the extra 044 fuel pump??
#9
Yep!
Also -- how did you notice lack of fuel? Fuel trims start creeping higher than .83 in the logs?

All this happened after I switched from the CarGraphics to Milltek exhaust....I did a thread on this back then....hope this helps.....

HI,When my car was being data logged on the dyno,,, The A/R was lean but my 72 injectors were not near their max duty cycle..So,we put a fuel pump pressure gauge on the fuel filter while we did a dyno pull and I noticed that the max pressure went down as the RPMS went above around 5800rpm,as I recall.So thats when we knew I needed another pump..

If you fit bigger injectors e.g. 60 or 72lb, keeping the 3.8fpr, you can run 1.35-1.38 bar max and your fuel duty cycle will be less than 100% all the time. As soon as you run over this your injectors will be at 100%, but importantly they will want to be open even more, although that is not possible e.g.107% at 1.45 bar.
Don't run larger injectors with 5fpr - that is a no go. Stick the 3.8fpr with injectors.
You could also swop the std fuel pump for a Bosch 044 at the same time. That would give you a little more coverage.
A 5fpr + Bosch 044 (no larger injectors) would be okay for about 1.25 bar. No more.
The above is on 18gs.

HI,IMO no..I looked at all those avenues when I needed more fuel....Just put the 044 pump inline and you will be good to go for the extra fuel...Marski has under the car kit..You can do a search and look up my thread on it..Mine is under the car also....Good Luck...
