I will be ~510rwhp with the NX Kit hit. I hope it will be enough.
Anyone know of anyone who lost a motor because if an inline pump gone bad?

It's not the best way of doing things. Look at it this way, how can it supply more volume when there is a restriction in front of it (the stock in tank pump)? The in line pump is not going to be able to pump any more then the in tank pump. The in tank Racetronix pump kits are pretty easy to install and will work perfectly for your application. I know they are a bit more, but you already have a good amount tied up in your car, why risk it now?

Just remember this . A pumps ability to pump volume is dependant on pressure. Lower presure = higher volume. When you add an inline pump and put a gauge between them you will find that there is far less pressure between the pumps that after the inline pump so the "system ability" goes up a good amount add a hotwire kit to the stock pump and it will be even better. A good intank pump is better but not much. All intank pumps currently available are Walbro either GSS340, GSS341, or F2000169 which are all the same pump with slightly different inlet and outlets. The jet pump in the take needs to be run by taking a small amount of the pumps output and sending to that to suck out the last few gallon of gas. some do this by installing a nipple in the top of the pump and some by putting a "T" in the outlet of the pump to connect the small line to.

An in-line pump for the F99+ modules is not the best solution as it can cause problems with the fuel system's functionality. Although our in-tank system is a bit more work to install than an in-line pump it would be well worth the time investment.

Depends on the application (NA/FI/N2O). We've taken heads/cam cars with decent size shots to a little past 650 RWHP. That was using a single pump Racetronix kit with a fuel rail mounted fuel pressure regulator and a return line.

If you need more fuel than our single in-tank system can provide it is time to consider losing the bucket and going with another solution such as our DP in-tank system.

Typical numbers based on adequate fuel volume assuming stable regulation (BSFC dependant):
600RWHP NA w/o booster (13.5V)
700RWHP NA w/booster (17V)
550RWHP FI w/o booster (13.5V)
650RWHP FI w/booster (17V)
Some customers have exceeded these numbers and some have fallen shy depending on their application. A 97/98 FMFPR system is highly recommended for all applications.
