Ok guys,
Maybe you can help me make a decision. I'm going to install a NXL kit when I can, but I'm sure I'll need to upgrade my fuel system. Currently my car is a big H/C car with stage II LS6 heads a healthy cam and all the boltons with 30lb. injectors and I'd like to run a 125 shot or somewhere around there. I was either going to go with an intank pump (maybe the Racetronix if it ever comes out) or install an inline like the Vortech T-Rex.
So if you were me, which one would you do? Which one is easier to install?.... I'm big on the easier installs if that's possible.
I don't have a problem cutting a hatch out of the metal above the fuel tank if it's easier to install an intank. TIA for the suggestions!

How much more trouble is it to do an intank? As I understand it, there isn't a direct drop in intank pump except for the Racetronix that isn't out yet... is that right? Would the inline T-REX along with the stock intank not support 550+RWHP? because that's what I'm going to be looking at 550-600RWHP with a 100/125 shot... I'm already at around 440 NA right now.

Hmmmm.... I thought I had heard of a few people on here like Poolfanatic that used a T-REX on his 550RWHP H/C nitrous car? Maybe even so that's still pushing it thin, if I decided to go to larger cubes later on I don't want to have to do this again so maybe the intank is best. Isn't it a b*tch to drop the fuel tank though? Wouldn't it just be easier to cut the hatch out of the metal right above it? I've heard several people complain about dropping the tank saying they'll never in their life do that again....

intake.....its quite a bit more work that installing a plug-and-play inline (kit) and it takes time, but it really is the best way to go.....it runs cooler/lasts longer, it flows more, and is quieter....
inline is just a band-aid unless you are actually pulling the intake out, sump the fuel tank (or custom tank), and then putting a BIG inline like the Areomotive 1000HP+ pump...... intake.....its a little work and it takes time, but it really is the best.....it runs cooler/lasts longer, it flows more, and is quieter....

Would you say it's still quite a bit more work for the intank if one were to consider the new plug n' play intank like the Racetronix set up? Just wondering..... I may do the inline anyway just because I'm looking for something "somewhat" easy right now......

i dont think the drop in racetronix willl be must easier then switching out the pump, its not that hard once you get inside.
I am selling my inline 255lph pump i had, that i dont need any more for $75 with the conectors (i went to a dual intank).
PM me if interested.

it "should" support up around 500rwhp (maybe an extra 50hp above stock punp alone) with the stock pump
yes i can include everything needed for it except the wire and relay. ill look to see if i have an extra relay but im not sure.

Smokin Hawk,
Thanks for the offer, but I guess 50 more RWHP probably won't cut it for what I need.
It's a great deal though.... I'll have to figure something else out because I need something that will do 550-575 at the wheels..... Guess I'll be looking at some intank setups or more beefy inline's. Thanks for your help though.

You can get the in-tank system and add a KB BAP or MSD BAP as a PnP option to the RX harness. This will support well over 600RWHP with a single pump running normal pressures with properly sized injectors.
It is still a good idea to re-locate the FPR to the fuel rail.

if you want to support your 550-575 rwhp, ANY inline with stock will not be enough. the stock pump will limit your fuel flow.
you have two choices, put a walbro intank, and make sure it gets plenty voltage or go to a sumped tank with a external pump.
THe cheapest way to do it would just buy a walbro $100, and run a wire from the altinator to power it, turning it on with a relay.
