    Hello, I have been a lurker here for a while and wanted to start posting, learning, and hopfully contributing to this forum. I notice there are a lot of top notch racers in here with a lot of experience, maybe one day I can be one of those guys. For now I'm just a small tire, door car, heads up racer with a blown alcohol SBC that's looking to win some races in 09, I'm cluless on tuneups and fuel systems. I've been able to run a full 08 season without blowing anything up. I finished 3rd in points for the heads up class true 10.5 behind 2 champions in my first ever racing series attempt.

    I'm currently upgrading my engine with some pretty top notch parts to hopefully give me the power to win some races and be competetive this year. I just have to learn how to tune. I've looked through out the site and can't really find a starting point. Is there "fuel systems for dummies" out there, I know Jim at HRE has his fuel system book, but haven't really heard too much feedback or reviews on it. I have a "basic" understanding on how it works, but not enough to effectively tune it for power. Can anybody recomend a starting point?

    Here is a pic of the car.

    Thanks!

    read plugs as well

    I run a couple of injected small block chevy's and a couple of alcohol jr's. reading plugs is a great skill to have, but in my opinion if you throw in an exaust gas temp recording device you can widdle down closer on your tune up. there are lots of different devices ranging in prices from cheap to OMG:rolleyes:. i run my cars a little bit rich as to not burn up parts. but having an accurate number vs. only a subjective reading of plugs can help to fine tune your tune up.

    p.s. don't forget the weather station:cool:

    book

    Bob Szabo's Fuel Injection book is a good starter. Go to www.racecarbook.com to order it. When you're done with that, his book 5000 hp on Methanol is good, but be ready for some chemistry and science to go with it.

    Look at some races in your region as far as divisionals and see if you can find an alcohol team to go learn from. Just remember you're there to learn, and you can't start off crew chief...

    Hope that helps!

    Thanks for the tips guys, I have been reading plugs, just a matter of how to read them correctly for my application. I don't have a weather station, but need to learn how one of these will help me tune. Also the way my headers are built I can't run probes, I was thinking after talking with some people to just run some o2 sensors when i get enough to buy a racepack. Will tuning to the o2 be as affective as EGTs?
