Currently, I have stg. 1 FTP, K&N filters and 3" beast tube. At what point should I upgrade the fuel system? Looking to purchase either 172mm or 180mm crank pulley with mid length headers. Also, what power gain can one expect from these two mods?

The "mods" you have installed have been shown to produce no benefit.

More boost (either crank pulley or SC pulley) & headers and a tune will likely net you 70 - 100 whp.

T9ja, we can set you up with a nice package that will add over 100rwhp with the necessary fueling upgrades.

Pm us if you are interested brotha

FTP Stg. 1 includes: H/E, Bosch pump, and the SC pulley plus the ECU reflash. How come they do not show any benefits? Have yet to dyno my car. Will probably do that soon to find out.

I'm guessing he read right over the Stage 1 and was only speaking to the filters and beast tubes. Your S/C pulley and re-tune did give a power increase.

E55Freak

you listed all cooling mods at first which is why he stated no benefits. When you add the pulley that will gain you some power....

HeissRod

In his first post, he listed:
Stage 1 FTP
K&N Filters
Beast Tubes

Stage 1 FTP Includes:
Bosch 010 Pump
FTP H/E
S/C Pulley
Re-tune

I have a eurocharged stage 1 and recently bought a larger crank pulley so having done lots of research and received plenty of excellent advice through this forum and from Shardul I feel I have good advice to offer.

If you are looking at a crank pulley to run in addition to the smaller sc pulley you will need the headers done plus extra cooling mods (split cooling with extra tank at least) plus upgrading your injectors. Even after these essential mods I wouldn't go over 168 or 172 on the crank pulley without even further modification. And if you did go all the way to 180mm with killer chiller, maybe meth, fuel rail etc it would be best to not use as a daily driver as the motor would need to be performing 100% all the time to avoid major problems like blowing pistons etc.

There are others here with much more knowledge than me but I'm pretty sure that's it essentially. Contact Shardul and he'll let u know exactly what will work in your scenario.

Before doing any of it, address your fuel filter. The change interval listed by MB is for stock cars. (plenty of margin). If you're over 40K miles, it is a near certainty that it is needing replaced. It's not cheap, but a leaned-out motor is a lot more.

Like how much are we talking about for fuel filters? My car is at 74K. Don't know if it has been changed.

Need to keep my setting to daily driving. So, which of those mods mentioned above will keep me in a daily driving mode. Don't want to be checking under the hood every 5 mins to see if nothing is broken.

Roughly $400-450 each for driver and passenger side, if you can do the work yourself.

Also when you start adding power like that then logging is the difference, a good logging system is not cheap but everything goes hand in hand, I have had situations where the logging system told me something was wrong and I caught it.

Also regarding the filters I think if you use a fuel system cleaner once in a while could be beneficial to the filters, just a thought but no proof

MindBend

The driver side has a filter assembly (a crazy looking filter) and the other side is where the pumps reside and is fed across the fuel tank from the filter assembly. While the pump side doesn't have a "filter" exactly the pumps have a pickup strainer that filters the big junk.

I just recently altered my fuel system by removing the stock filter and putting two inline filters in its place. Also added a return line off the looped rail with a aftermarket fpr as I removed the factory fpr beneath the sender unit.

So far it is performing perfect. If you watch fuel pressure on wot runs, it drops a descent amount. I saw at least 10psi drop on the blower setup. With this relatively small investment, fuel pressure rises 1psi for every pound of boost.

Can you share pics of the setup but if it's a shop secret I understand

Your stock car will dyno about 415 to 430 RWHP and most add fuel upgrades at about 500 rwhp range. Most cars show to have enough fuel with just a tune and pulley but depends on how old your pumps are working and if your fuel system is in 100% flow shape. Lot of old fuel sytems out there with a lot fo miles on them.

Before returning to Germany I purchased a set of the latest/greatest pumps/filter assemblies which are on the shelf at the moment. As I'm at about 65k on the clock I will be replacing the original units within the next couple of weeks. Never had ethanol laced fuel and have used Techron on a regular basis. Never a problem and no leaks. I'm anxious to see how the existing filter looks and will post up pics after the replacement.

Hulk

In for pics of the filter, wouldn't be surprised if they look good

Is this perhaps a service that will be offered for our vehicles at the BiP shop !? Are you still field testing it? It almost sounds like the conversion would cost less or equal to changing the OEM unit!
