Grrrrrrr!!!! *******

[Motorhead350]

New problem here. The car is now running only 0-3psi and I do not know why. I have checked the tubing and all is well and if there was a leak the car wouldn't be running anyway as I found out before. I called up a good source and he told me to make sure the blower is spinning by taking off the intake tube and all is well. Later I was told to disconnect the battery to reset the computer because the weather has been very hot for the past few weeks.... so the car stores info (which I didn't know about) for the past 30 days on the subject of the weather. This will determine how much power the car can handle if it's 50 or 90 outside and if it's too hot the car will push 350hp as suppose to 460.

By resetting the computer it will clear all of the past info and will forget about those 90 degree days. Tonight it's cool. After I did this I took the car for another ride from 0-70. The car is still acting like a stock Marauder with 4:10s and will NOT give me any boost until about 6,100rpm and it does kick in, but only about 2-3 psi. I'm thinking this is still a computer issue from what I heard.

This is very irritating and wasn't expecting to have to deal with B.S. like this. The car is running and functioning fine, but it is acting as if it is stock.:banghead::cheesed::argh :

Suggestions please!!! :mad2::mad2::mad2::mad2:

[MACFORD88]

It Maybe That The Marauder Wants To Be Stock And Dose Not Like The Boost.

Anyone wanna trade? :flamer:

[Richy04]

How is the boost regulated (popoff or pressure relief?) on your blower? I would look there first.. Which one (blower kit) did you purchase?

He got a fit/procharger kit i believe



Ill take your marauder, just leave the s/c kit on Just in case i get it to work, if not ill put it on my blade :P

[Richy04]

Ok, just looked at the FIT system. Barring anything physically wrong with the blower, look at the surge valve and related protection devices. Make sure the belt is not slipping and look for leaks. If its leaking, most likely you will know it!

[Richy04]

also check the boost gauge itself, it may have failed.. FYI, some good vacuum gauges will accomodate and show boost, but try another boost gauge if you suspect a failure of the gauge.

[RCSignals]

I was thinking it could be the gauge, but he says he can't feel the boost in that it drives like it's N/A

Dominic, did this just start?

[Motorhead350]

I just noticed and this maybe why I was running disappointing track times. The boost will work, but not until it's past 6,100 rpm. Nothing is leaking because if it was (like I stated) the car wouldn't run. The belt seems fine, but I think someone needs to look at this. I hardly have an idea as to whats going on, let alone what the problem is. :mad2:

[martyo]

Belt is slipping.

[Haggis]

Belt is slipping.

Marty are you loosing weight?

If you cant change oil or dont own a $2000+ toolbox, you should not have a blower on your car.

Dang... I'm only at $1995.00......:mad:

Dom check your belt.....

[Zack]

Sounds like a stuck open Bypass valve.
It does happen, occassionally

+2 Thats putting it nicely....

[RF Overlord]

Dom, your kit's a Procharger, right? Have you contacted Greg at F.I.T.?

[ctrlraven]

I would say the belt also. One of my friends has a procharger on his mustang gt and his belt was slipping and only showing 3-4 psi of boost, got the correct sized belt and is at his promised 8-9 psi now.

[Motorhead350]

Dom, your kit's a Procharger, right? Have you contacted Greg at F.I.T.?

No I haven't. I didn't wanna call him at 11pm, I wouldn't care, but to most people that's rude. I'll call him today.

[RCSignals]

$2,000 + tool box? What's it made of? titanium?

[Breadfan]

How old is your tensioner?

[Drewstang]

I like my $580 box because it looks like a $2000+ box.:

I second that as a probable cause. Just check to see how much swing you have left on the tensioner.

I can change oil, that might be the problem. I may have gotten blower oil on my belt. We'll see.

[magindat]

No I haven't. I didn't wanna call him at 11pm, I wouldn't care, but to most people that's rude. I'll call him today.

I've called him at 11 PM on a Sunday night. He answers!!!

[magindat]

As I said in your other thread, call DR. He has a tool for reaching the tensioner from behind the blower without taking the blower off.

You don't need a $2K+ toolbox, just the tool from DR!!!!

[FordNut]

As I said in your other thread, call DR. He has a tool for reaching the tensioner from behind the blower without taking the blower off.

You do still have to remove the blower to replace the belt.

Disconnect the intake pipe and discharge tubes from the head unit. Release tension on the belt. While holding the tensioner so that it is not putting pressure on the belt, slide the belt off the water pump pulley. Release the tensioner slowly. Note that if you position the tool too high up on the tensioner you will not be able to release the tensioner because the wrench will hit the blower. Now that the tension is off the belt, unbolt the blower mounting bracket. Remove the head unit, taking care to release the belt from the blower pulley and to not drop/lose the idler pulley located at the left-hand alternator mounting bolt.

Remove the belt, clean all the pulleys, install new belt, then re-install the head unit and connect all the tubing.

^^^^^I dont miss anything of what brian said.

[Motorhead350]

Great. I'll get on this in about 20 minutes! ;)

[cyclopsram]

ya all needs da spell check fer sure... ambitious, occasionally, don't, can't, losing, what's, does... makes it hard to read posts.

[superford3]

who ever told you that 90 degree days may cause you to lose 100hp is smoking crack and should not be touching a car

[MM_BKK]

If there's a lot of black belt dust around the timing cover area or the tensioner, your belt is slipping big time.

[FordNut]

...edit...

Wow, I can't believe I said that.

Corn likker will make ya say stoopid stuff.

[Motorhead350]

Well like I stated in the other thread.... this problem hasn't been figured out yet. :mad2:

[Zack]

Its the bypass valve Dominick.

[Motorhead350]

How do I fix that Zack?

[Zack]

You need to take it off and look to see if it is fully seated.
If it is not, there is your problem.

[HwyCruiser]

Motorhead350, this is what the bypass valve looks like:

http://www.procharger.com/images/artwork/bypass_valves.jpg

It's the one on the left, probably anodized black. It was installed between the nipple on the bottom on your intake pipe and a "T" pipe after the intercooler. It'll have a vacuum hose connected to the top. Check to see that the bypass valve linkage isn't hung up on anything.

BTW, you weren't messing around with the Predator about the same time this started happening were you?

[Motorhead350]

Ya we messed with that thing last night and still nothing.

[HwyCruiser]

...BTW, you weren't messing around with the Predator about the same time this started happening were you?

Barring any intake or bypass leaks, I just want to ask this again to make sure your custom tune is still in the car. What's your idle rpm reading at?

[Motorhead350]

It might be the blow off valve now or a very small leak. I don't think I can get back to it until friday night.

[Motorhead350]

I thought I had a minor air leak coming from the tube that goes into the intercooler, so I took off the tube and put it back on further and tighter. Soon as I did that the car was still the same. I took it on a highway on ramp (yes at 1:45am) and gave it hell. The car was still pushing 3psi and at the top end around 6,000rpm thats when all the power comes it. It came in so strong this time it blew the tube off the blower and I was stranded for about 30 minutes because I didn't bring any tools.

So it's clear that this isn't another small leak, it seems like the blower just isn't functioning properly. Does it make add up to anyone? :shake:

[snowbird]

Doubt it. The blower is a (relatively) simple device. It build boost with rotating speed. Just look at any Procharger dynosheet. It cannot store pressure for a while and then releasing all of a sudden. My ex was able to do this but that is another story.

While people on this board are trying their best to help you out at 1000-2000 miles away, I would suggest that you find a good mecanic in your area that would help you out in the coming months. He would learn to know your car/set-up and it would be a good "investment" to take care of your car. Chicago area is certainly big enough to have a lot of knowledgeable speed shops that deals with blower set-up.

Also, take the time to domesticate your set-up gradually. Beating the crap out of it in the middle of the night is looking for disaster IMO. Before finding the problem, you might have a very rich or lean condition that could just blow the engine.

Zack suggested a look at the surge valve and I think it might be worth a look. There,s not that much of possibilities: the belt and or tensioner, the surge valve actuation, the PCV hosing and valve actuation, and/or a dead squirrel or a rag stuck in one of the tube or intercooler.

Good luck.

[fastblackmerc]

Surely whomever you bought the blower from will provide some assistance..... I agree with snowbird, you need to find a good mechanic.

Didn't you post about wanting a quick & cheap blower install? Remember you get what you pay for......

[martyo]

So it's clear that this isn't another small leak, it seems like the blower just isn't functioning properly. Does it make add up to anyone? :shake:

How much boost were you making at the top end?

If you were making enough boost to blow the tubing off, that would usually mean more than 3 psi.

Are you sure yoru gauge is accurate?

[fastblackmerc]

How much boost were you making at the top end?

If you were making enough boost to blow the tubing off, that would usually mean more than 3 psi.

Are you sure yoru gauge is accurate?

Or the tubing and where it connects to the blower is oily from the oil change..... clean everything good with alcohol.

[Motorhead350]

How much boost were you making at the top end?

It would push 3 usually and when it went past 6,000 rpm it would go nuts for a second. I don't know how much boost at that rpm level.

[MarauderTJA]

It would push 3 usually and when it went past 6,000 rpm it would go nuts for a second. I don't know how much boost at that rpm level.

You should be getting into full boost around 3500 RPM. I am sure it is something minor that is wrong. It is just finding the problem. You'll get it straightened out.

[Local Boy]

Here's a thought...Is there a system (electrical) that triggers the relief source (valve) to open when you hit the rev. limiter @6,000?

If so, perhaps it's wired backwards, and is staying open...when it should be close (from 0 to 6,000 rpm's)...and closing (at the rev. limit) when it should open...

This would explain ...The "coming on all of the sudden" behavior...Because that means the valve is closing @6,000rpms...sending full boost from a fully spooled "Maxed out" MONSTER and blows the connections right off it's base...

WOW! That must of been one hell... of few seconds... of just complete MONSTER POWER...scary...

ALOHA

[MM_BKK]

Remember you get what you pay for......

What do you mean by that?

What is the best system out there that money can buy? I'm sure with that system, someone have had problems with it, no?

There's more than one way to skin a cat.

[Motorhead350]

Let's just forget what he said and not get this thread closed over baby talk. Does anyone know if I can get a valve at a performance parts store or do I have to special order a special Procharger one for the Marauder?

[RCSignals]

FIT should be able to send you a valve, no?

[Motorhead350]

I want it now and I could send them the recept for what they owe me. Are these valves universal for Prochargers?

I didn't mean the supercharger. I meant the installation of said supercharger.

[Motorhead350]

Well I didn't install it. I don't wanna say who did, but I really think something is up with a part or there is a leak. Remember this was working fine for the first week.

[MM_BKK]

I didn't mean the supercharger. I meant the installation of said supercharger.

The bypass valve is not electrically controlled. It's just a simple vacuum operated diaphragm. When there is engine vacuum ~12" or more, the valve is opened to bypass the supercharger to prevent surging especially at high cruising speed (65-75 MPH). When you're heavy on the throttle, naturally the vacuum goes away and the valve is supposed to closed allowing the S/C to build boost.

DOM, take this valve out and look at its butterfly blade. It should be fully closed with no vacuum hooked up to it. If it's opened any at all, then you're going to be losing boost pressure. You can test this valve with a handheld vacuum pump, you'll see it opening up as you apply vacuum to it and it should fully closed when you bleed out the vacuum.

Hope this will shed light on it. ;)

[RCSignals]

I'd talk to FIT first before I just bought one and sent them the bill. Maybe you have already.

[HwyCruiser]

Dom, please take it to Zack and have him look at it. If you can still drive it and it hasn't thrown any codes then it's probably a fairly obvious fix to someone who knows what they are looking for - and Zack's the man I'd bet on.

[Motorhead350]

Zack gets the car sunday if I can't get this right tonight. The Valve actually looks just like the way it should so this is really getting to me. :mad:

Geeze if i was close that close to Zack ,i woulda been there 5 pages ago..

[Zack]

It had a kinked Bypass valve vacuum line. It would pull in (open) but not release. I got under the car and it was in the wide open position. I unkinked the hose and lubed the bypass linkage. Seems good now.
It also has a bad boost gauge.
Problem solved in 5 minutes.

See I knew it was something simple and stupid. I was having fun all night long with the car and taking a few friends for a ride. Now I'm looking into a new boost gauge and maybe a volts one if I decide to change the two instead of getting just a matching one. Thanks again Zack. Sorry I drove you to drinking. :o

Your boost gauge is probably warrantied, but if not I have a new one I'd sell.

Glad it was an easy fix.

I actually got it for free and have no idea how old it is. Thanks for the offer, but I'm going to a store today and seeing what styles are out there besides AutoMeter.... but I'll probably just get another one.

There are many different gauge makers out there, and Autometer has a slough of different styles themselves, in both mechanical and electric.
