How far is too far, regarding the FL5 fuel system?

[AspecR]

1. My goal is to make my car do everything better than OEM, yet still maintaining or going beyond the fit and feel of OEM. This applies to both on street and track (not drag racing). Having a decent crossover with minimal compromises. I know there always is.

2. My power goal is whatever my tuner determines is safe. I am not really concerned with the numbers per say.

3. For the third time in thread, I have addressed that I stood corrected for my error in using the term OEM+. I own a full track Porsche 911 GTB3 class racecar. So anything streetable that is modded such as this is OEM+ to me and that is what I initially meant. Again I have addressed this in the thread and understand this term is not generally accepted as I perceive it.

Again, the question at hand is in reference to the need for the hanger and plumbing as linked in the original post. We are here as a community to discuss this here.

What type of builds require such a setup for the FK8 that Radium went out of their way to develope and release. There must of been a large need as there would have been no money to be made, right?

This has been great. Thanks to all for the input.

I asked about your power goal simply because that determines the parts you'll need. Based on what you've stated that you already have your car should make anywhere between 550whp - 575whp depending on how far your tuner wants to push it.

A new fuel hanger setup is unnecessary at that power level unless you plan to make more power in the future.

Most won't admit it but after 450whp these cars tend to lose the great balance they have, even with Hondata traction control UNLESS running 200TW tires regularly. 500+whp is great when you're stuck to the tail of some exotic car that can't believe they're unable to gap a Honda though.

Thank you! This is what I beleived the general consensus was as well. Yes, I too think that traction will be a challenge. One of the reasons I will be using 200TW as you suggest. 500hp sounds good to me for a FWD 4 banger.

However, I am here to learn with my eyes and ears open. I hope we can invoke some tuners to get into the conversation as well.

So, this is how I understand the current possible issue with the OEM FL5 fuel hanger. Contained within the fuel hanger is a fuel filter element. This element is integrated into the fuel hanger and cannot be replaced without that portion of the hanger assembly being replaced. Do not get this confused with the pre-filter "sock" that is attached the pump itself.

This filter element has been known to break down to the constant exposure of E blended fuels that we typically run. This break down does not happen immediately but could happen within a short duration of time. The exact amount is unknown, however after two years, I was advised that an individuals was showing signs of break down.

Periodic flushing of the system with 93 octane fuel will increase the life of the filter element as well and is not a bad idea to do for other components as well.

So the Radium hanger will eliminate this design feature that the OEM has. The filter will then be relocated to the engine bay where it is easily serviceable and of course will be fully compatible with E blended fuels.

Therfore, I think I am safe to go forward with my build. As long as I flush my system periodically.

Also, with the power levels we are all running with stock blocks. I do not think the plumbing kit would be required. Hopefully the external fuel filter will be adaptable to the stock fuel lines without needing further.

Of course, please chime in build the conversation. Thanks

Hopefully the Radium hanger will be released sooner than later. I will definitely be adding it to my build.

I ran 265 wide Conti ECS02 summers with 470whp, they were able to grip well at all times. I’m currently running 285 wide Conti DWS06+ uhp all seasons, and not struggling with traction.

Unless you’re running a 200TW that activates when cold/colder, I’m certain they’ll struggle to keep up with either Conti option I listed. I know this because I ran Yokohama AD08R before the ECS02, and was always spinning in 1st, 2nd and top of 3rd

I have zero experience with the ECS02 so I trust your word on it. PS4S, P Zero and other tires in that class struggled to hold on. My perspective comes from South Florida where average temps are higher than most and it isn’t abnormal for guys making good power to daily their car on 200tw tires that’ll get up to temp after a couple pulls.

Give them a go next if you’d like

They’re quite popular now with Type R and S owners. Lots of big power builds in Florida and Texas could be running them as well. I’ve also had them out at Tail of the Dragon, and encountered brake fade with Motul RBF600 and Paragon R5 before the tires got greasy

I am not sure why we have changed the topic of concern on my thread to tires here. But, I do appreciate the suggestions. Except with my 18x10+40 spec TE37's, there would be no way in hell I am running a 265 on any tire.

But I would consider the 275x35R18 in ECS02. But since that wheel setup is mainly going to be used on track and if I was to pick a Conti tire. It would probably be the Continental ExtremeContact Force in 275/35ZR18.
