Data Logger Worth it or Not?
 

I have a 66 Chevy II with 283 Super Stock car. Are data loggers really worth the money for carburator applications? What value do they add? Best brands?

Thanks,
Avery

ABSOLUTELY.......
I've used Racepak since 2007. Everyone I know that has "finally" spent the money to get a data logger, wished they would've done it sooner............

The data you gain will eliminate guesswork and reliance on trackside " you spun the tires " observations .
Just having the basics of engine ,driveshaft and O2 will help save time and money by providing solid visual data graphs that can be overlaid to compare good and bad runs and make informed shock and suspension adjustments.
Real world ,on the track O2 data is very helpful in finding the tuneup that not only can pick up ET for a heads up run ,but also find the perfect bracket mode tuneup that delivers consistency.
Additional channels like oil and fuel pressure can also help catch problems before they result in destruction

Yes for sure. I have 1 on bracket/ small tire car with nitrous sometimes. I have gained 1/10 in 1/4 ET due to reading graph and seeing Converter was wrong by about 200 rpm and car was going to lean at finish line. I'm not the smartest guy but made me smarter and faster. Also I watched how oil pressure was fluctuating alot going down track. Adding 1/2 a quart of oil straightened out pressure reading and maybe saved a engine from being hurt.

Friend of ours had similar thoughts to yours, first time out with his Racepak system he had an oil pressure issue, discovered a broken oil pump pickup and saved an expensive engine.
He no longer wonders the value of data acquisition,

See you at the races,

Yes- and look into RPM Performance. Simpler, reliable and a higher level of personal support than Racepak.

I agree with the yes answers. Having the basic data allow tuning a car to be very consistent. I like the Racepac system.

My son Jon and I have similar 340 Stock Demon.
He dyno's his engines and has a Data Logger with
a lot of channels.

I do not use either one of those and mostly scratch the
seat of my pants.

Last week at Sac we ran side by side at the same exact
weight and the finish was '.003 in my favor.

Of course = He reminds me I was racing over 30 years in these
cars when he was born.!

Re: Data Logger Worth it or Not?
 

Buddy of mine got talked into a pretty basic Racepac a few years ago. Has owned and raced the same car for many decades and thought he knew every thing about it (and his driving).

Put it in, took it to the track and made a few test hits. Looked at the data and couldn't believe what he didn't know.

Made some changes and the car is deadly now.

I'm a believer. Add video and you're set.

The first thing I learned with my data recorder is that I didn’t drive the car very consistent.
