Good morning all, I hope everyone had a nice Christmas.

As the title suggests, I'm needing to gather enough fuel to run my PS1 efficiently and optimally and I already know my fuel pump is going to be limiting me. My question is which fuel pump to pick.

I have studied the TTFS, Dorchester and Spool performance and was looking g for best value for money but also easiest to work with and tune as well as what is actually needed, 150/180 etc.

My car currently has the OEM updated LPFP which I was told is flex fuel capable and so far have had no issues loading up with ethanol.

I do not really run ethanol of I can help it. My goal for this car is quick and reliable daily with around 400-450 HP that you can get in and drive.

Given the above, would it be wise to spring for the larger volume fuel pump or just get the lower volume and save a few $$?

Also I'll need some spark plug advice as I was running NGK 2 step colder plugs and honestly didn't love them. I think the burn was too cool for my application and gap should have been adjusted. I'm about to run a stock set of plugs for right now before I retune the car with hopes of a HPFP install in the future. For the time being my car is FBO w/PS1 on regular BM3 OTS stage 2 map. Would it be fine to run the OEM bosch plugs with their factory gap of around .035-.038 or will it give me problem off the bat? Thank you guys for the input.

I feel like ps1 will be just fine on stock hpfp

See I've heard differs and I've heard the same. I really want some owners of this setup to chime in as it puzzles me as well. Tuners are more than welcome as well.

Need a little more information:

Do you plan to use any ethanol or meth?

Will you get a custom tune?

Will you eventually go to a bigger turbo?

I will get a custom tune yes, I guess I should have stated that as well. My idea is to Max it out and dial it back a bit. Additionally I was going to run the N52 exhaust cams on the car and tune those into the ps1. No meth no ethanol or not very regularly.

You should be able to max out a PS1 without a problem on pump gas with stock HPFP. You will run out of octane before you run out of fuel.

The tricky thing is you say ethanol 'not very regularly'. I think you need to make a decision now, because running ethanol or not is going to be the deciding factor on whether or not you need a HPFP for your setup. You can probably get away with a light ethanol mix if you are just looking for a little extra octane, but it completely depends on how much boost your custome tune is going to run, and you would likely be at the limit of the stock HPFP in that case.

If you dont mind spending the money to future proof your build and have the ability to run ethanol whenever you want and not worry about being at the HPFP limit, get a upgraded HPFP and be done with it. Stage 1 HPFP is more than enough for a PS1 even with moderately high ethanol mixes. Also, if you go custom tune, running an ethanol mix is really what will let you get the most out of your turbo upgrade, especially if your pump gas isnt the greatest, so consider that as well.

Ideally it would be nice to have an e85 or race gas map to run and integrate an ethanol sensor in the car and utilize the BM3 new map features with ethanol sensing.

[Munchi435i]

If you have access to E85 then I'd suggest getting at least a stage 1 HPFP. You will yield more power with a ethanol mix in the E30-E40 range. I'm not sure when BM3 will start selling there new board package but once it does theoretically you won't need a custom tune. So if your banking on getting that hardware from BM3 I'd suggest holding off on thr custom tune but still purchase and upgraded HPFP.

Did you already buy the ps1? Just wondering because if you are thinking about getting an upgraded hpfp that costs twice as much as a ps1 it doesn't really sound like you are on a tight budget here and in that case might as well just get ps2

[harkes]

You can run 17psi to redline with PS2 and stock HPFP on 93. That is more power than you will ever make on the PS1. If response is key then the PS1 is a better choice though. I sometimes miss the instant torque with the stock/PS1. With the PS2 you need to be above 3k.

Turbo has been in my car for 10k+ miles. I didn't want pure stage 2 I'm not building a drag car. I have 134k miles on this car. I drive it 15k a year. I want to get in, start it and drive it and have it perform like a stock turbo car with the light power bump. I'm very well aware that there are "better" options however that's subjective and I wasn't asking that to start with.

[Chicken_Joe]

Ideally my thought process was ability to switch fueling on the fly without having to worry about the fueling demand from the pump on engine. I have been following BM3 advances and am very pleased with what they are doing. I will eventually integrate a FF analyzer into the lines and try to utilize the BM3 adaptability feature when it's ready. Why do I want a HPFP? Because I prefer over built than under built.

I'm not here to be the fastest 1/4 mile, stoplight or YouTube sensation. I want to get in the damn car, start it without worrying if some shit is going to break and then drive it like I stole it.

I don't feel my requirements are overreaching. Everybody has to make their point PS1 is "pOiNtLeSs" however 400-450 HP is more than enough. Besides I've driven PS2 cars and I like where my power comes on line vs the PS2. It has a distinct lag. And the car I drove was tuned by Shoup (or however you spell it)

Not hating on it at all, I'm in the same boat as u and am not impressed with ps2 for the price and increased lag.

How do you like the ps1? Was it worth it and a noticeable gain over stock turbo stg 2 fbo? Also what tune are you currently running?

I ran the PS1 prior to the PS2. For city driving and response it is miles better than the PS2. And running it at 100% WGDC it will light up the rear wheels in almost any gear coming on boost which is actually good fun

Turbo lag really doesn't bother me much, but that instant torque is certainly tempting. Was the difference between stock turbo and PS1 super noticeable, assuming same tune (or did you run PS1 with a custom tune)? If I can run pump and make around 400whp on PS1 that is definitely a tempting option, especially considering the price advantage.

I did not notice any difference in lag between stock and PS1. Ran both on JB4. Any tune will aim to produce as little lag as possible.

Correct me if I'm wrong, but I'm thinking 400hp may not be realistic with pwg ps1, pump gas, and stock fuel system.

Was there any noticeable gains/improvement with ps1 over stock turbo in normal/spirited driving or did you need to get above 5000rpm to even know that you had the ps1 on the car?

Have to get above 45-5000. That's just the mechanical differences. Remember PS1 is a ~20hp upgrade over EWG and ~40 for PWG so not night and day but noticeable.

Ya I figured as much... waste of money for max 40hp lol

The hp is one thing. The other is that with the PS1 you can tune the car to run eg flat 16psi so it doesn't feel like it is dying up top. You will not yield max hp like this but get a car with great response and a NA feeling powerband.
I have done this with the PS2 but with around 19psi instead.

I find a difference but without a tune most won't notice it. After 5k no tune it fills the drop off in the power band. Before 5k I notice somewhat of a little dip crossing the 3000rpm mark but it flattens out after. And I'm not building a straight line car.
