www.hre.com and Spud Miller at Fuel Injection Enterproses have math formulas that will get you a starting baseline to work from. If your pump is an 80A, it's around a 6.8 gallon a minute pump. You are fat! With your cubic inches and the intake that you have, your fat. You could go to a 100 pill in the main, and it would be close I bet. The other thing that so far nobody mentioned is that when you change your main pill, if your barrel valve is spot on, you will have to adjust it a flat or two. Until you get close with your tune-up, you will want to make changes of 12 - 16 number on your main pill. You're looking to make heat in the motor and show heat on the plugs. Once you get close, then make changes of 4 numbers at a time: 100, 96, 92 or 100, 104, 108. Once your happy with how the car is running, then you might want to think about adding a high speed lean-out to further dial in the system.





I sent my whole setup to fuel injection enterprises to start with, as I was new at the mechanical alky injection also. My tuneups were very close from him. I have since fine tuned my tuneup with minor variances from his initial tuneups. Imop VERY well worth having done being new to the injection as I was. Worth every penny. Saved me a ton of headache.

Me too, my whole manifold and fuel pump went to Kinsler and they fixed all kinds of wore out stuff on my manifold I didn't even know about. Then they had record of my stuff and I could call them and they were VERY helpful.
You know happened the first time I ran my car? We quialified #1 and was the fastest car at every race the whole season, every race!! And I never ran a injected car before that.

The motor looks good, nice and cleanly put togeather.
The thing that caught my eye was your quick disconnect jet can, imo it should not be mounted solid like that to the fuel cell. Vibration can cause the pill to come off it's seat and cause leanness for a second. fwiw. Tire shake does happen sometimes when you start making hp.

Slingshot383 and others. I was going to make a post and ask this question. I put a new set of Champion C59CX plugs in mine,with 7-10 mins warm up time and 7 1/8 mile passes driving back from each pass. The plugs look new no color what-so-ever,you can only see color on about 2 threads down on the plugs. It runs great,the idle is about 1200-1500 I have to lean it out @ the start of the day to warm it up.

As good as it runs I really hate to start changing things,but the racer in me makes me think I may need to do a little more tuning. I don't want to leave anything on the table with the tune-up. The more I learn about my terminators the better I like them. And I have a lot more to learn.

PS How does everyone else's plugs look?

I tune by using NGK plugs, -8 or -9 for 15/1. The plating will scorch off the base of the plug some as you get leaner, closer to optimum. I like to see about 3/4 of the base scorched, threads still shiny and unchanged. You will have to check all the plugs and eventually will see if you have one cylinder warmer than the rest. I go by that one for saftey. My #5 & 8 run a touch warm, so those are the two I check for tuneup, check the rest later to make sure all the rest are in line.

From what you said I wouldn't change anything, unless your really bored!
ET is the ultimate barometer. If it is running that well don't change a thing. I never had any color on my injected plugs either. White and slightly wet.

Hyper will get there... injection is as complicated as a garden hose but there is definatly a learning curve.

Hyper, did you mention your pump size in this thread?? It could be a problem if it's too large.

Better be careful, running it like that will wipe the rings off like your holding the face against a grinder.
No kidding.
Should be able to warm the engine up some 140-15- deg in normal time and use maybe 2-4 gallons tops.
