Bolt on fuel pressure regulator?

Has anyone used one of these and how good are they. Seem a little cheaper and would do the same trick, but I dont see many DSM's with these.

Yeah, they work fine that is the full throttle speed fpr, just like the spoolin up fpr and old charged air fpr. They have been used on dsms quite a bit, I also recommend buying it from importevolution as well, Ryan is a great guy and his customer service is top notch as well as his prices.

or just buy it straight from Full Throttle Speed like i did, its a great product, just installed it about 3 weeks ago.

Jay, also remember to look here for some examples:

Im still not sure what im going to do. My goal is 350whp or close to. Im going with a safc and 550's so its easier on tuning. Also some meth injection.

So my next question is where does the 190 walboro become a bottle neck? What is the max power you can get out of it? Im either going with that FPR, and a 255 or just a 190. If the 190 can handle 350 than thats what I want to do.

Thanks for all the quick replys

Jason, for most tuners the 190lph will be enough for any "16G-or-under" turbocharger. You will be close to maxing out its flow capacity with an EVOIII16G hitting 350+whp, but this pump is very good and very reliable. The thread below is also great to look at to see the approximate flow rates:

Thanks man, I just dont want to waist money because turbo upgrade wont be for a long time.

I sprung for the non-ss Aeromotive kit because it's only $40 more. I didn't want an afpr that direct bolts to the rail. I wanted to relocate it next to the brake fluid reservoir. Also, the one you linked doesn't have 3 extra ports where you can run lines to other peripherals like nitrous, in car gauge, etc.

The price diff is so small I didn't see any reason to go with the more limited option.

 

[JayRolla]

I will never run nos, since im going with meth injection. Also I dont need a guage inside, on the FPR is fine. Im thinking of just going with a 190lph pump and no FPR at all.

Doing this is fine. The only thing that I would recommend you take a look at are the Lancer Evolution VIII fuel pumps. When these pumps are re-wired, they flow at similar rates as the 190lph pumps. I only suggest this as an option because you can find these pumps used for about $20, compared to the $100 you will spend on the 190. But it doesn't matter too much. Either one will fit your needs.

I don't have the link right now (because the main page of the "Tech Guide" section is unavailable) but if you get a chance, take a look at the install guide of the Lancer Evolution VIII fuel pump.

Ive been looking at the link with the fuel numbers and want to make sure i am reading it right

Say i want to use 660cc @ 80% IDC will support 37.90lbs/min with a Walboro 190lph (Rewired) and running say 22psi (49.71lbs/min). Would that set up be fine? I was always curious why everyone just said a 255+FPR not matter what the question, when people can use 660's or even 750cc (43.07lbs/min) fine off a rewired 190.

Maybe, but the way I look at it, I wouldn't want any limitations. I stopped saying "never" a couple years ago as I keep adding more and more mods, breaking my vow. I think it's because I've put in so much $ I probably won't ever stop upgrading.

Btw, I plan on water/meth and nos eventually.

You ever thought of using a 255 with a 1g nt stock fpr? I have not used it myself but know many people who have with great success.

I would not recommend that. Now that the "Tech Guide" section is up-and-running again, please take a look at the link and the quote below from the 1G Upgrade Guide:



Go down to Step #9:

The stock fuel pump will not be able to supply the needed fuel for anything over 16psi of boost. Though you won't need to go past that in this stage, it's still cheap insurance to put in at least a 190Lph fuel pump to ensure you have enough fuel in case you want to raise the boost with race gas in the tank. It's also a good idea to re-wire the fuel pump for consistent fuel pressure. If you go with a 255lph pump, you'll need an adjustable fuel pressure regulator.

To put it simply, your OEM fuel pressure regulator will not be able to handle the extra flow capacity of the 255lph fuel pump, so purchasing an aftermarket AFPR is essential. Even if we're talking about the N/T fuel pressure regulator, why risk it?

 

[JayRolla]

Yea I think ive decided to go with a 190 since im not going with anything bigger than my 16g. One day when I do build my stoker with a monstor turbo I will upgrade but for now I should be good with the 190.

 

[Skunked tsi]

You may not recommend it, but it works and he is looking for a cheaper alternative that is why I suggested it.
Tyler

 

[JayRolla]

And he also put his opinion in. Its ok for people to disagree, but I would like to know why it works. Im pretty sure a 255 will overrun the n/t's also.

It does. And just like those people who say that a 255 with the stock turbo regulator works you have to discount the claims for the stock N/T regulator does much better. There might be less of a difference between the overrun and non-overrun pressure but you'll still have the problem.
