T2 Fuel pump in NA
Any advantages in this other then higher fuel pressure? My friends giving it to me for free and his T2 only has 35k miles on it so why not.

Stock fuel system is good up to 250 HP or so. I had a street port, exhaust, and intake on my S5 NA and it still ran rich.

No point. It will NOT make the car run rich though, the TII's and the N/A's have the SAME fuel rail pressure.... the TII pump is juts capable of a higher volume....
No need unless you are heavily ported, with every bolt on. .. and that's still questionable, but a good safetly measure.
Built up N/A's just don't need quite as much fuel at WOT as a TII (one making the same power) does. Especially if you are tuned leaner with an S-AFC. The N/A's run leaner.

Funny, because my N/A runs out of gas at 8100rpm as viewable on the a/f gauge. I have a big street port and every bolt on as you say... Pulls strong up untill it leans out and power cuts out. Even with the S-afc fattening it up at the higher revs, it simply cannot deliver.
Thats a pretty bullshit theory saying that the TII needs more fuel at the same power levels than an N/A. True the TII tends to run a hair richer, but not enough to equate to the vast differences in the two fuel systems. 550cc injectors are roughly 20% larger than the 460's that N/A's use. Getting an N/A's power to equal that of a TII will take a substantial increase in fuel system capacity. Running 4 460's at 100% duty cycle is not accurately stating that the system is capable of the HP.
