Reading plugs is every bit as good...better even than thermocouples. Not as convenient, but at least as accurate.

How you going to use an IR gun? You cold idle, but that's it. Underway -where it matters, ain't gonna work.

Here is what it looked like:

 

Can you prove that please. Or are you using your imagination again. You need to read more on tuning.

 

So you are trying to avoid saying that you agree with me an IR gun is not the way to do this by replying as asking a question!

 

Well if you don't need to smog it to register and license it then the sky is the limit. Start with basic foundation builders like headers, free flowing exhaust and a good intake like the Renegade. I don't think the savings in porting your stock manifold justifies the effort when there is a quality piece on the vendors self for a reasonable price. Once you have the car running well with a good intake and exhaust then you can make internal motor improvements one at a time so you can sort things out as you go. Unless you have a lot of sbc experience and with CFI then have at it but if you did have a lot of experience you probably won't be here asking for advice. Making changes one at time allows you to keep track of the effects - good or bad - and recover from mistakes if needed.

Good luck.

 

listen to ^this guy giving CFI advice....and he doesn't have one! I especially like the part about the value of porting the intake. Cardo....you know what a WELL ported CFI intake is worth in the 1/4 mile? I do. You know how much it costs to port a CFI intake? I do.


Prove what; that plug reads are every bit as good as thermocouples? Sure I can prove it. Come here, and I'll show you. Thermocouples have some error. The error doesn't matter much, but there is some. When you're reading plugs you're reading the actual combustion event -if you do it right. Can't get much more accurate than that. Thermocouples are easy though and give you (virtually) real time data. So for sure they're easier to use but they're not better. They also cost money. Not many on here are going to go buy an 8 cylinder EGT set up. Not many are going to read plugs either, unfortunately, but at least it's attainable/doable for anyone, and for no money.

I'm not avoiding anything. An IR gun is not the way to do it. Unless you want to remove your hood, and stand on the fender well while your buddy drives your car.

 

It's time for a Quaalude, Tom. Suggestions should always be considered, even if we don't agree with the other guy. The IR gun could be used on a chassis dyno, rather than having a buddy ride along under your hood! (I'm not arguing one way or the other!)

All I'm saying is that my '84 CFI has surprised a few people, and I'm sure I don't have all the right answers.

 

Yep, that is true. An IR gun would work on a dyno. Good point.

 

I went with a mild cam, renegade, 1.65 rockers, heads, full smog stuff delete, and melrose exhaust system.
i ended up going with an ebl flash ecm to get everything running right...

 

I know this is almost a decade old, But an LT-1 exhaust will bolt right in to a Crossfire equipped corvette? Im trying to find a budget option for my old, and rotted out exhaust.
