you need the regular one.. the high pressure one is for pressures of 70+'ish.. we run at 50 at WOT.Keith - Chicago<br /><a href=\"http://www.hptuners.com\" target=\"_blank\">HP Tuners - PCM Reprogramming</a><br /><a href=\"http://www.dxsoftware.com/magnus/\" target=\"_blank\">97 Firebird V6 to LS1 swap</a><br /><b>V8 9.967@132.78</b> 1.322 60\' NA Heads/Cam<br /><b>V8 10.295@128.48</b> 1.363 60\' NA Cam Only<br /><b>V8 10.987@119.31</b> 1.422 60\' NA Stock Internals<br /><b>V6 13.674@98.22</b> NA<br /><b>V6 12.394@104.91</b> N20 100HPComment

If your fuel PSI will be over 70 then yes.
the high output one just flows better at HIGHER psi's.. it flows the same at the lower ones.Keith - Chicago<br /><a href=\"http://www.hptuners.com\" target=\"_blank\">HP Tuners - PCM Reprogramming</a><br /><a href=\"http://www.dxsoftware.com/magnus/\" target=\"_blank\">97 Firebird V6 to LS1 swap</a><br /><b>V8 9.967@132.78</b> 1.322 60\' NA Heads/Cam<br /><b>V8 10.295@128.48</b> 1.363 60\' NA Cam Only<br /><b>V8 10.987@119.31</b> 1.422 60\' NA Stock Internals<br /><b>V6 13.674@98.22</b> NA<br /><b>V6 12.394@104.91</b> N20 100HPComment

Would the fuel pressure ever be over 50 psi when you hit the nitrous? Should i get the other one over the regular one since i will be running nitrous?

Prepare for some serious damage here. Slowbraeater, Keith is an extremely accomodating person, don't post anything rude about him for not returning your email, he gets probably 250 or better on any given day. I'm not swinging off his nuts here, but I've known him for over 2 years now and he is one of the nicest people I've ever met. I mean the guy is willing to do just about anything for anyone, don't give him **** cause he didn't answer your lame *** question that could have probably been answered just by doing a search of previous threads. I swear, every time I see you post something, it's usually useless drivel. The answer to your question is yes, on the bottle, you will see over 50 psi if your nitrous kit uses pressure against the fuel pressure diaphragm to increase line pressure to the fuel rail, will you see over 60 psi? No, just go with the basic Walbro 255lph in tank.
Slacker, I recommend the same fuel pump for you, with our injector flow rates, it has more fuel capability than you will ever need.
xjarayax, you probably don't need the 90psi pump, even using a 1:1 FMU, your fuel pressure will only increase to 70 psi anyway, why spend extra money when it's not needed and can be used better elsewhere.<a href=\"http://www.fullthrottlev6.com\" target=\"_blank\">www.fullthrottlev6.com</a><br /><a href=\"http://www.chitownracing.com\" target=\"_blank\">www.chitownracing.com</a>Comment

Thanks Tom...
SLOWBRAEATER, I did respond to your e-mails.. however AOL rejected my last e-mail saying you were not accepting e-mails from my account.. so I left it at that. I don't blame you for the e-mail rejection but I just don't have time to que it up and try it every so often.
Like Tom said, a dry shot that increases FP by pressing up against the FPR may bump PSI up a little.
With a wet shot you will see 50PSI at WOT.. or whatever your stock regulator supports as long as the fuel is there.
I remember Mike Huff saying his FP was upwards of 100PSI with boost.. in that case I would defiately go with the high psi pump.
Last time I checked, the autoperformance site has charts that show flow rates for the pumps at different PSI's.. you can see the high PSI one only works better... at higher PSI's.. hence the name.Keith - Chicago<br /><a href=\"http://www.hptuners.com\" target=\"_blank\">HP Tuners - PCM Reprogramming</a><br /><a href=\"http://www.dxsoftware.com/magnus/\" target=\"_blank\">97 Firebird V6 to LS1 swap</a><br /><b>V8 9.967@132.78</b> 1.322 60\' NA Heads/Cam<br /><b>V8 10.295@128.48</b> 1.363 60\' NA Cam Only<br /><b>V8 10.987@119.31</b> 1.422 60\' NA Stock Internals<br /><b>V6 13.674@98.22</b> NA<br /><b>V6 12.394@104.91</b> N20 100HPComment

Well i am now going to go with a supercharger for sure within the next couple of months so i guess the high pressure one is the way to go in that case,<b><a href=\"http://www.sick-sixx.com\" target=\"_blank\">SICK-SIXX MEMBER</a></b><br />NA 14.345 with a 1.863 60 foot<br />Nitrous 13.03@99.5 with a 1.63 60 foot<br /><br />2000 Camaro 3.8L A4: USE TO HAVE Comp Cam 210/220 .535/.547 113lsa 111 I/C, Port and Polished Heads, NX Wet Kit 100 Shot, CPRA made by CP, RK Sport HeadersComment

sorry keith i have no idea why you cant send me emails, and bird of prey if my question was a cheesy lame question that could have been answered by a search i wouldnt have asked it pal!! I did numerous searches on direct port shots and yes i know magnus knows alot that is why i emailed him the questions about direct port systems so lose the attitude because i wasnt giving you or magnus one, sheesh some people.. I emailed magnus because i know he knows his sh** about the fbody and like i said if my question was answered on here i wouldnt have emailed him it!Longtubes, true duals, ram air, caspers tps tec, ls1 26lb injectors, supersix powerpack, heads milled .020, comp cam .507 220/224 114 ls, forged internals and chromeoly pushrods, bored .030 over, tb spacer, tranny built with stiffer springs and kevlar bands, bigger servo, transgo stage 3 shift kit, edge 3600 stall, 1 pc aluminum ds, 3.73 superior gears, lsd rear ,custom pcm tuning, walbro 255 in tank,Comment

I swear a few of my e-mails went through, did they not?
IMHO, best place to get answers is here though. I am not right about everything and over here you can get more oppinions from several very smart 3.8 owners.
