Quick and Simple ?

I just adjusted the FP to 42 lbs line on, 47 lbs line off. Blms dropped down to 137. Cars idling much smoother as well. I believe i have cracks in the crossover pipe and pOssibly the Passenger side header. I hear it but dont kno exactly where its coming from. That could explain blms i suppose

[Steve Wood]

would have bet a thousand bucks your gauge was bad.

What are your blms at steady cruise at 70 mph?

Jack the car up, get under it while idling and run your hands around the cross over joints and behind the Y in the headers where 3 and 5 come together

Havent drove it on the highway yet. I can def say the car pulls soo strong tho. Im still NOT going wide open throttle yet due to me still tuning and stuff. Im just amazed at the diff of the throttle response, idle, etc that these adjustments have made. Let u kno when i take it cruising. I really appreciate all the help too. I know i have a long way to go, but im just happy to see some progress.

As you now have too much fuel pressure, it would seem that you must have a major air leak somewhere...I am trying to find out if the problem is constant between blm cells or mainly at idle.

If you can drive the car, then put it in second and get it up to about 2000 rpm at a steady speed, then flip over to blms and tell me what they are

[phil_long]

will do sir. 

[Steve Wood]

you can do a smoke test to see how bad it is leaking...go to the parts store and see if they have a can of Seafoam to dribble into the throttlebody.

Here are some instructions.. .. http://www.gnttype.org/techarea/maintenance/cleaner.html

Basically, you are going to unplug the maf, rotate the pipe from the intercooler to the throttlebody so that it is pointed up instead of at the innercooler, crank the engine and run it at a fast idle....dribbl e the Seafoam, or any other brand of top engine cleaner into the pipe while keeping the engine running fast enuf to not flood it and kill it...you can even use Marvel Mystery oil...smoke will come out of the tail pipes big time.  It will also come out of any leaks in the exhaust under the hood....see where it is coming from and fix the leaks

sorry for the two day hiatus. Thats a good idea Steve.  I did the test for the BLMS at 2000 RPM cruising in 2nd gear, and the BLMS where at 141.

[phil_long]

And, should I lower the FP back down to 38 lbs before I pack this gauge up and send it back?

[Steve Wood]

the fuel pressure for a factory chip was pretty close to 40 psi with the hose removed from the regulator...I think.  We often set them to 43 for a bit more fuel.

Most aftermarket chips are calibrated for 43-again hose off.

It is still lean according to your blms and it seems to be lean through out the range so I would not lower it from where you have it until you get it sorted out. 

You also need to find out if your fuel pump is good or bad by seeing if it increases pressure on a one to one basis.  You need to make or buy a hot wire to allow the pump to perform as well as possible and that would be my first step.

[phil_long]

Yeah Steve, that was definately my next step.  purchasing the hotwire kit.  also, since the FP gauge that i was using is faulty, what brand do you suggest i go with for a RELIABLE FP gauge?

[Steve Wood]

Well, I always make my own as you can see.  I like the larger gauge and that is an Ashcroft, high accuracy gauge that I got from Graingers long ago.  Think it was rated at 2% accuracy.   It probably cost what this kit costs which should also work ok   http://www.metcomotorsports.com/proddetail.asp?prod=MFP0003&cat=107

[daveismissing]

My Metco seems to be correct.

Buy?-I thought you were a harness maker by vocation Phil?

[phil_long]

Damn Steve, you stay on top of it!!  Thanks man.  Thats a nice gauge.  So, my next purchase will be the hotwire kit and this FP gauge kit.  I wont be able to purchase for another 2 weeks tho. I'll box yours up and send it back to ya sir.  Thanks for everything

[phil_long]

My Metco seems to be correct.

Buy?-I thought you were a harness maker by vocation Phil?

Lol, yes, buy.  I like to try and keep people employed!

[phil_long]

I think im gonna start a thread showing my latest project at work that i did in a weeks time.  the job was def suppose to take at LEAST a week and a half to two weeks
