ALL OF YOU WITH SUPERCHARGERS OR TURBOS NEED REPLY PLEASE!!! in much need of help

[twofast4nu]

Okay,
As all of you know, or atleast most of you know. I'm running a custom setup on my 3.4. We'll i'm trying to work my way around two problems, rather three i guess.

One is the EGR valve? my car is equiped with the digital unit, which i see no need for. The way it sets in relation to the engine is kinda a problem due to the headers. Rksport "designed" a major flaw(s) in their units. first off those of you with the 3.4 setup will notice how the weight of the EGR is distributed off to the side of the header creating alot of undue stress. I had to replace the pass side unit do to the flang breaking at the weld form the weight. Also, it may be me, but i have problems with the EGR. this is the 2nd one i've added to my car. They seem to melt down? and leak. I had problems with mine last week so i removed it, blocked off the opening on the header, and moved the EGR over by the computer....just to hang loose so i didn't throw trouble codes. I was just wondering if i could get rid of it? or if i could literally bypass it or something.

Second thing. I bought the Holley adjustable fuel pressure regulator designed for the 305 and 350 TPI fbody. i stuck it on the car....and now have no real idea on where to set it at pressure wise. i have a paxton fuel pressure guage under the hood running off the shrader valve(stem removed) I'm not sure where to set it.....so i tried to tune it in with my autometer A/F guage. So far thats just been a hit and miss operation. I need more info on fuel systems? I'm running stock injectors...but plan on upgrading before the april event. Also, i read in my haynes manual(the most generic car book known to the camaro enthusiast) that the PSI on the fuel rail should be set at 41-47 PSI? well, how does that relate to LBS ? as in injector size? ect.

And last but least? Bypass valve? how are you guys running yours? i've looped mine back into the system before, but after i added the new intake piping to the SC, i decided to just add a K&N filter breather(big one) to it. Its alot louder, but i wonder which is more effective?

Once again any help is appreciated. I love helping others on this site, and try not to ask questions unless in dire need of the answer.....and the truth is i'm depending on you guys to help. Thanks again. Hopefully i'll get this all straightened out and be ready for the april event.....so i can race you guys [img]graemlins/burnout.gif[/img] . Cause ya know, i'm all about trying to be the fastest supercharged "3.4" on the site.....wait i see and advantage to that..cause so far i'm the only one :rolleyes: .

Nic-

#1 On my turboed 3.4 I completely removed the Egr and also blocked the path into the intake, JB Weld around the edges to prevent leaks helps too! ;) I've never had any problem with the car running bad because of this. However you might want to disconnect the SES light because it comes on and off due to the temp. of the engine.

#2 On the AFPR I found that if the setting was too rich it was like the O2 sensors were getting coated in unburnt gas and the A?F gauge was going all over the map. Lean<----->Rich. Also leaks on the headers made problems too sometimes. I actually had to run it leaner and *slowly* bring up the fuel pressure till it was adjusted properly.

#3 My blow-off valve was exposed to open air, it's just cool venting the turbo. :D But I haven't had any dyno proof that it's not maximizing boost or anything. :rolleyes:

Can either one of you give me a extact partlist? or as much as you can?

I have a 95 firebird, and my dream is to super or turbo it, and you two seem to have it well done..

thanks

Are there any gains to be had from removing the egr system. Also, would it be possible to install a resistor or something into the connector to fool the computer so no ses light? Thanks

As far as I know the computer doesn't diagnose the effectiveness of the EGR system by it being plugged in alone. If that is one of the ways, then you could just take off the head of the EGR(the back part holding the three sylinoids), or connect some resistors of the same resistance as the coils in the sylinoids to the right wires. But, I have read that the computer sees that the EGR is working by looking at the MAP sensor for a difference in pressure once the EGR is opened. So to get around that you'd have to fool the EGR some way. I took mine off cuz I was tiered of seeing all that carbon buildup in the intake, and I just put up with the SES light.

remove the egr all together, it will cause a SES, but oh well.no harm done.

on the AFPR, start at about 40lbs at idle and work from there, adjust SLOWLY, quarter turns at a time at most, it causes a big difference in my car.

I think what you meant by bypass valve is the blow off valve? you don't need a filter on that, it only lets air out, since pressure on the other side of the system is above atmospheric pressure.
I plan on running mine open.

If you're really interested I'd be willing to sell my intercooled turbo "kit". Email me if you want a more complete parts list. :D

Thanks for replying guys.

I've had little time to check out what everyone has wrote, but i do appreciate the help. I love to help others when they ask, so one again thanks to all that replied.

Also, my kit. The kit was originally a climas racing kit. I bought it second hand and made it into a better setup(in my view) As for power gain? It has made a significant change.......on my motor. I have no idea what it would do on someone elses 3.4. I've did alot of internal work to mine. I will say this, if your thinking of doing a supercharger setup. Keep this in mind. You need alot of parts, lotsa time, and be willing to do 99.9% of the work on your own. Most shops wont venture into doing something no one has really done. Thus for the reason you see a few of us on here with custom setups.

I can send info on my setup to anyone who wants it. But i ask that you ask for specific answers. Its really hard to explain it because it's still a work in progress if ya know what i mean.

My e-mail is twofast4nu@yahoo.com

Thanks again guys. -Nick-

um..k. thats wrong. an SES light sets a code in the computer, for the computer to take stronger control of the engine based on what is wrong. hence the reason my car runs like *** rite now. the fact that the ignition system isnt running right sets an SES code. does it just leave the thing alone? no. it retards the timing and it resets the firing order to 1 when it looses the signal of the igntion from the crankshaft. dont take an SES light light. the computer is using that SES light to tune your car down so nothing goes wrong and alerting you to the problem so that it can be fixed and will run properly..

dont believe me? ask a engine mechanic.


anyway, Nick -- as for your fuel system. what kind of injectors are you going to upgrade to? you have to know - that injectors can determine the amount of hp that your car gives out. yes a fuel pressure regulator will help a little, but only so much.

formula:
hp * bsfc / cyls / duty cycle = lb/hr

on a 3.4L V6, 24#/hr injectors:
hp*.5/6/.8=24
hp=24/.5*6*.8
hp=230.4

so a 24#/hr injector on a 3.4L v6 can support up to 230.4 hp on the stock 41psi fuel pressure.

ok, JAmes , he never ran a EGR, had constant SES, dynoed it many times, installed EGR dynoed again, no changes [img]smile.gif[/img]

[black34v6]

&lt;shrugs&gt; ok. james had a custom computer program. perhaps Ed wright set something up so that the computer didnt do anything as a result of the EGR not being there?

i wouldnt trust that statement till i see a stock 3.4 remove its EGR and dyno and all that.

sorry, just need a bit o proof here of a "unmodified" computer - cause not everyone is gonna spend the money to alter their computer programming to not run their EGR.

just sayin...

[Tiago]

Ed didn't do anything on his computer except remove speed limiter, set shift points and half assed adjust fuel maps, he coud'nt even do that very well.

Jsut unhook it and zup tie it under your hood. SES lights are annoying, I was happy once I got mone under control. [img]smile.gif[/img]

If I was a better electircian, I would sit there with a voltage testor and see waht I could put in place of the egr to set it so the signals are the same. Only problem is I think it changes with engien speed so you would have to make something that could do it. But I am no expert, but I think the egr is more complicated then a simple sensor.
