I would upgrade the fuel pump anywhere past a 150 shot also, at least this was the advise given to me at one time when I considered a 175 shot.

 

Probably the same chick that said urs was the biggest she ever seen too! lmao!

I was running low 11s, 6yrs ago with a stock bottom end 5.7 LS1 spraying 200 out the gate. Just cuz u aint got ***** enough to do it dont act like it cant be done!

Do i do it nowadays???? Well hell no, im running a cell and big pump! Lol

 

I've ran a few bottles of 200 hp shot off the rail before. I would say it's about 170hp if you are talking rwhp though. It can be done for sure.

As far as being safe? Well that depends on the persons definition of safe...but to me, I feel safe doing it.

 

I ran 200 off rail with a walboro and fuel pressure dropped to 45-48.

 

If she woulda told me mine was the biggest I would have told her she didn't need to flatter me...It's not about havin *****...It's about not bein a retard. I coulda fucked that chick without a rubber too, but I used my brain instead...

You're an idiot and shouldn't give advice just because you've done it and was ok. You even contradicted yourself in your last sentence by saying you don't do it now! Can it be done? Hell yeah it can! Hell you could prolly spray 400 off the rail a couple times with the stock pump. It just depends on how hard his pump is working now. He could spray 200 using the rail for several years to come, he could make one pass, he could make half a pass...Ya never know...

 

I would agree with ^^ but I'm not looking for a vacation...

i plan on a 200 shot in the future with supporting "safety" mods.. FPSS, fuel pressure guage, wideband, stock intank pump with an inline

 

Here's the thing about nitrous...It doesn't matter what "safety mods" you have, hell it doesn't even matter if god himself put the tune up in the car; you're forcing more oxygen than was ever intended into your engine. If you're not totally cool with the fact that at any moment you could burn your **** up, nitrous isn't for you.

Am I trying to persuade you not to use nitrous? Hell no! That ***** fun! Is using your fuel rail to supply enough fuel for a 200shit hit of nitrous safe? Who's to say yes or no? Just in this thread alone we have one guy that says he was ok doin it for several years and then another says he lost fuel pressure even with an upgraded fuel pump.

I prolly shouldn't have called that fella an idiot. It worked for him and it may work the OP. Just be sure to keep an eye on it and GOOD LUCK!

 

Thanks guys, My pump has alot of miles on it and DBrods is going to make me fuel cell to use my stock sending unit. I'll upgrade the pump for sure. what pump do you guys reccomend to fit in the stock sending unit? and do I need a aftermarket fuel pressure regulator? i'm just trying to get everything together so When I do take it to the shop to get it 4 linked its all there.

 

I would put a large inline pump if going the fuel cell route. The magnafuel 4303 fuel pump has worked great even with lots of street driving in texas heat. My only complaint is that I haven't installed the correct fuel level sender and the low fuel light is always on.
