Remove this?
 

Can i remove the brake boost line?
What does it do?

Why would you ever want to remove it? That line supplies vacuum to your power brakes. Yes, you need it unless you enjoy practically standing on your brake pedal to stop the car.

The reason would be that it would be much easier to route the fuel hoses without it.
But now when I know exactly what it does, there´s no way I´m removing it!
Thanks for the answer!

Man mole your set up is AWESOME!

i highly doubt that is his considering he did not know what that booster line did

GT

It is his.

You read my mind...

I think you should remove the line. The car will be lighter and there will be less clutter in the engine bay. It's just like some emissions device. Ignore all the above responses.

Mr. Hailers, although your response re: weight issue is correct, you incorrectly stated that there would be less clutter. If I remember correctly, in your thread from months back, entitled, " what a mutter, look at da clutter", you stated that pixie dust would completely hide any eyesores. Are you going back on your previous statement? Molehill, around halloween, at Burger King, they give the dust away with a kids meal. Be patient, and you can get rid of the eyesore then. LOL.

he was being sarcastic

You guys! Of course it´s my car, but I have been thinking of other things than the ugly brake booster line! I´ve just started to route the fuel lines in my beatiful engine bay ;) and I just thought that since everything else that is for comfort is gone this little sucker could go to... but as I said before, now when I know exactly what it´s for it´s gonna stay!
Btw there is like 100 FCs in Sweden and I don´t have many people to ask here, and a little corny line in the bay isn´t the first thing we look into!
But now I know!

molehill, how can you have done that much to your car with all the mods and not know what that does. I dont want to sound like an ass, i mean there are tones of little things that i dont know but should.....but that is on almost every car.

I haven´t payed that much attention to that particular part. All I knew was that it had something with the braking system to do. Now I know exactly what it does! perhaps I should mention that I´m in a hurry... That´s why I posted this silly question, I could have saved some time be just removing that line, but know the hoses will have to take another route!

Molehill, you either had someone else do the work to your car, or I just came off a tequila sunrise. Dude, that is one the most gorgeous under the hood vaginas Ive seen on a RX lately, so please tell me that you did the work yourself, and got into my bottle, cause Id quit drinking for that set up. Lie to me and say you got in my bottle. Appologies to you for my inconsiderate post. Dude, read next time, and you wont make an ass out of yourself like I have done so many times.

i was kind of surprised at the question after seeing the engine bay pic too.. :p:

I have done everything except the CNC machining and the welding.
I´ve thought everything out myself. Haven´t bought a kit, or anything.
And as a mention before there are very few FC here in Sweden, so I don´t have alot of people to ask.
There is not one singel tuner that tunes rotary engines here!

No one else has touched the enginebay! I have done drawings to all the stuff that has been CNC machined, and I´ve cut the pipes and my friend just welded them together.
I´ve fabricated the fixture for the exhaust manifold so I got it the way I wanted it...
No one else has touched a screw on my car!!

When I first started this project 3 years ago I didn´t know anything about cars,
and now I just have to start the car before this fall, so therefore the stupid incompetent question!

Sorry if I´ve made a foul out of myself, and I will not ask anymore questions!

Don't be so thin skinned. They're just fucking with you. The intercooler ducts look professional. But I don't have much use for cars that don't have enough wiring. humor

Notice how one bozo called my remark SARCASTIC? I didn't let that get me down, even though I KNOW I have not one sarcastic bone in my body.

I just take things a bit to personal... But that´s only because I love my car!
And after 3 years of waiting, I´m impatient to get her out on the streets, so it´s not totally impossible that I might ask another stupid question ;)

but I think I read in the FSM first from now one :)

Dude, now your being silly. Relax, I caught a lot of shit for my first few threads. They said" shut up, read, then come back and dont post, shut up and read. Have learned more here than any freaking manual could teach. Your car is clean and dynamic. Keep it that way, and I'd really get rid of that line. Once you drive it once, who needs brakes, thats what they made guard rails for. Peace! RUF RUF RUF

being okay to remove a brake boost line is not sarcastic???

Post count means nothing... I regularly take a 1000 or two off my total. And there are people with post counts in the 1000s that still are clueless.

Post count should never be considered. Only the correct answer should be considered.

It could have been one of my many mistakes? END

I have another question. There are som kind of metal disk inside the wheels, they seems to be pretty heavy! It´s one by each wheel, would it be okay to remove them? I really think the car would weigh much less without them... ;)

Molehill, as long as you are removing the brake boost line, what the hell, might as well remove those diskies, rotors as people with slow down devices call them. One more weight saving idea. Inside each tire, if the air gets stale, It picks up excessive weight. Make sure to change the air in the tires weekly. And lastly, if you dont smoke, the ashtray and light will definitely improve your horsepower. Peace. RUF RUF RUF

molehill: whats the deal with the water pump? i dont see one. Nice setup.
- Jared

As stated in his sig "DC E-waterpump" its an electric water pump.

-Andrew

NOW we're getting somewhere. A serious mod. Just extra weight. They gave you a steering wheel to avoid static objects and a key to turn the engine off and come to a stop. Press on with the weight reduction. I'll stop now. On to the serious replies.

well i feel stupid, i never bother reading sigs.

That sounds good! Consider them gone... but unfortunately I have to keep the steering wheel with this mod. But considering the weight difference the steering wheel is the one I keep!

As Andrew wrote, it´s a Davies Craig electric water pump. I´ll post pics when it´s installed.
Thanks!

i have 16,000 posts on another forum, means nothing to me.

just relax and consider it a learning experience, without a little pain some things are easily forgotten.

What the hell does how many posts have got anything to do with helping, or insulting new people like us? No offense molehill, but what the hell does his knowledge, or lack thereof, have anything to do with most posts. I think Ill start a thread asking for pics of engine bay for anyone with more than 100 posts, who can compare with this vision of loveliness.

If you remove that then you might as well but some drum brakes on there as well cus your going to be setting your car back about 25 years...

Let us know how that works out. I'm very curious to know why Davies Craig resorted to legal bullying (threats of expensive law suits) when AutoSpeed tried to publish the results of extensive testing of their EWP and controller several years ago. They're still effectively gagged, which I think is disgusting behaviour from an aftermarket supplier. I emailed Davies Craig twice asking for their side of the story but they didn't have the courtesy to reply... :(

Funny you said that... 90kph + Rain = My FC in the gaurd rail (only minor body damage...Thank GOD)

On topic people...Unless you have something helpful to add, please don't post.

I was reading somewhere...that some race cars do not run a booster. Saying it gives better feel.

But they do not have a booster period. They just don't undo the vacuum tap.

James

I´m kind of skeptical to the quality of the pump just by looking at it, but alot of people in Australia use the Davies Craig EWP. I would like to read the test result from AutoSpeed, and I think that that kind of behaviour just gives Davies Craig a bad reputation!
But since I have bought it, I will test it and se if it works. I will however buy another one to have in reserve just incase... just don´t like that plastic feeling.

I´ve mounted the pump now...

OK, I have been scanning through looking for an answer to my question, and came across this post again. Dog is off the hooch right now, so I have just one question? What did you finally do with the brake booster line? Also, like previously stated, nice f-king engine bay. When its up and running, the sun shines in December in California, come on out and make mine purty.

PEACE THE DOG p.s. yes, I am a jerk, but I can live with that. SORRY!!

I removed the boost line, together with the brake disks, steering wheel, drivetrain and the big "thing" in the engine bay. The "thing" kinda looks like a big hamburger laying on the side... but it´s alot bigger and attached to the gearbox.

Of course I left it as i is! I think being able to stop is a pretty good idea...

I would love to come to California in December, the snow is laying thick here in Sweden then! But the transportation of the car over the sea, just for a cruise in the Californian sun is a little bit to much trouble ;P

Glad to see you are still here. American humor is complicated, like these f-kin cars. Just disconnect the driveshaft from the rear-end, drop down to 13 degrees, hold there with wire and duct tape, put propeller on end of shaft, tape the tires to two, not one, two surfboards, fill up with gas, and I'll have the meatballs ready when you arrive. Glad to see you have not lost your sense of humor.

PEACE THE DOG
