Intercooler

[Alpha D]

That would be awesome.

As soon as i get a better side mount intercooler. I will install that quickely out in the cold :( Drive it around for a a few days. See how she does. I think a lack of a proper air to fuel ratio is causing some problems to. Since i think Your maf measures your air intake which is affected by engine speeds and so on.

Now if you have a leak in the intake system and you start to build boost. Its suppose to adjust and all that good stuff Correct?

Now then since i don't have the proper amount of air to fuel mixture the engine is suppose to have. It runs or seems to be running Super Rich. My plugs were really black at the tips after only about 5miles of driving.

Is there any possibility that because of the car burning so rich a little bit of fuel could still be washing oil away from the cylinder walls causing the compression reading to be even lower then it is suppose to be? Because its not sealed up properly? Not only that but the rings not being seated yet, if the motor was truly rebuild?

To much fuel in the cylinders can and will cause lower compression readings. A wideband would help you get a handle on how much air/fuel your actually running though. Unfortunatly those early cars didnt have much for computer scan data, so I think thats about the only way of checking your A/F ratio. Black plugs does tell you its running rich, but how rich and at what rpm its getting rich is what you need to find out.

[Alpha D]

Ok that sounds very reasonable. From a gut feeling i would guess it starts burning very rich from 3000rpm untill you let of. Because you can here all of the compressed air coming out the side of the intercooler.

Which is why i am guessing it burns very rich around that rpm. I will be picking up a Intercooler here shortly. I need a Boost gauge, as well as a wide band. Those wide bands are pricey though.

worth every penny

you shouldnt be delivering fuel when you're doing a compression test.

[Spikesoftail]

Sorry by that I meant gas washed cylinders will cause low compression. Yes definatly should have fuel and ignition disabled for a compression test.

[Alpha D]

No of course the Fuel was disabled I just disconnected my Injector harness plugs. I was referring to after driving. Thinking maybe it takes a while for the oil to to form a tight seal on the walls resulting in a higher compression reading. I dont know its just what i thought could be a possibility.

I have another question. How bad actually are low compression readings? Would it depend what the cause for the low reading is? I dont mean to sound stupid or want to damage my motor. But could i not just run a little bit more Boost? Once the motor is broken in?

[Alpha D]

I guess i should buy a wide band. I will need to learn how to operate one. I am pretty much clueless. Ill do some research though. Boost Guage, Wide Band. Those two things will give me somewhat of a insight into whats going on under the hood. Now with the wideband would i need to tune my self? I would rather have someone off the forum adjust it or take it to map or something.

[twack]

if you dont have dsmlink, safc, or maft, you have no way to tune your car. all you can do is get it to stock and running good. unless you want to buy a fuel computer. if your on a stock setup no tuning will be necessary

[Alpha D]

I see. Well Safc 2 should be a good start. As for now i will just fix the side mount. See how the car drives after that,and go from there.
