Help!! My SSR losing power when accelerating!!

Floorex · 04-01-2006, 06:20 AM

I Installed a magna charge on my 03 SSR and for the last month everything was fantastic. Within the last week it started feeling sluggish. If you drive like an old lady its fine but once you really step on it you lose power for a sec and then it takes off. I thought the booster fuel pump was making an excessive noise and thought it was defective and called for a replacement so last night I recieved a replacement from magnusson and installed it. It ran slightly better but still not up to par. aAnybody got any ideas?

Ok it is hard when you can't drive it or even hear it, Number one sounds like your traction control is kicking in, Next could be your torque manement, Next could be a problem with the charger, Next could be the tranny slipping, You really don't get the full effect of super charging without a tranny that will hold up to the xtra power without slipping and a better torque converter

What you are going to need to do is pull the fuel pressure regulator. I think that one of the O-Rings are torn. Make sure to bleed off the fuel pressure before you pull the regulator and then you will need to go and get a new o-ring and put a very light coat of Vaseline on it so it slips back in without catching. If that is not it then please feel free to give me a call and I can help you out.

Mine used to have a slight delay when I punched it from a dead stop.

I'd be at a dead stop. I would punch it. It would delay and almost even bog down. Then it would kick in and haul.

I put in a 3000 stall torque converter and the delay is now totally GONE!

JimGnitecki · 04-02-2006, 04:58 PM

There should be no delay, and from Floorex's description, there was none until just recently. Something went wrong, and it needs to be diagnosed and repaired before he blows up the engine.

20056speedssr is on the right track here. Examine the possibilities, and narrow down to the actual cause. Do NOT drive it like this at large throttle openings, as real damage can be done if there is an air/fuel mixture problem.

Yes I agree you need to find the problem without driving it too much. Wrong A/F could cause major internal engine damage.

It may sound pretty elementary but if you suspect an A/F problem you might check your MAF. Its easy to check and if its contaminated its easy to clean. Especially if you are using an OIL on cotton gauze filter if may be a source of A/F problems.

Just a thought.

I have spoken with Floorex a few times in the last week and have his problem pinned down to the fuel preasure regulator. Last I spoke with him he was going to give me a call if he had any further problems.

That is the first thing I would do. It is fast to do.

Joe-

Sounds like your providing some more of that great after the sale support for the MagnaCharger again.

Just got back from being out of the country and away from this Forum for a bit. I should have looked at all the previous posts in this thread and found you were involved with helping Floorex out with his fuel problem.

Typically the fuel preasure regulator is the fault on the 03-04 SSR with the MagnaCharger. I didnt sell Floorex his supercharger but I am more then willing to help anyone I can. Thanks for the compliment!

I am wondering if Vaseline is an acceptable lube to use on o rings, as Vaseline is a petrolatum product. Wouldn't that attack the neoprene and cause it to break down? I would think a silicone lube would be much more inert, yes, no?

SA13355 - Yes, you are completely correct that a silicone lube would be better with the o-rings. Remember that most have some Vaseline in their home readily available and you just want to use a very little amount. It is only to help keep the o-rings from binding while you are pushing them into the housing.

Floorex - I am still waiting for a reply back on how it is running now? I hope all is well, feel free to give me a call anytime. Thanks!

First I want to thank Joe for all of his help.. Thank You Joe!!!At first i thought it was the fuel regulator because when I swiveled it the problem temporarily go away. Anyways I took my car to a performance shop. The fuel pump pressure in the tank dropped to zero when in boost. Took it to chevy they changed the fuel pump in the tank and it is running better than it ever did. The performance shop charged me nothing for diagnosing the problem so I bought a supermaxx header system from them and should have that installed this week. All you guys are great and thanks for your help!!

JimGnitecki · 04-11-2006, 04:58 PM

You are fortunate. Fuel problems when in supercharged mode can be deadly to the engine.

I am seriosuly thinking about a fuel pressure gauge for my own supercharged SSR, as well as a boost guage.

One issue is where to put them. I don't want to irrevocably butcher up the exisitng auxiliary gauge panel, nor any of the interior trim. I want to ADD the two gauges somehow, but where I can see them.

This is one of those cases where one of the LED fuel pressure systems that goes RED when the pressure drops might make sense, as a lean A/F ratio can cook a supercharged engine pretty quickly.

The desire for the boost guuage is based on my growing theory that the actual boost attained may actually be lower than we think if there are significant airflow mods in place in addition to the supercharger kit.

Floorex - I am glad that they were able to diagnose and get you in the right direction for the fix. The 03-04 Fuel system uses the 2 pumps so it makes it harder to diagnose at least from the phone. On the 05-06 when the fuel pressure goes out it is either the MagnaVolt or the stock pump which is easy to diagnose when you bypass the MagnaVolt. It was my pleasure talking with you.

JimG - I want to take a stock guage package and put Fuel Pressure, Air Fuel Ratio and Boost. Several of the aftermarket guage companies have guages that fit the holes in the guage package.

Whenever increasing airflow you will want to take a boost reference reading to make sure that you didn't loose boost with the extra flow. The cam that you have and the cam that I have set up for the head cam package will maintain boost. The extra flow may take going down to a 2.9 or 2.8 pulley to reach a safe 6-7 psi boost again.
