S197 My first DYNO

[302FAM]

Getting ready for my first dyno tune. Any advice to consider for this situation...

2012 Boss 302 (S clone with many upgrades, including Ford Racing IM, Cam, throttle body as far as power goes). 93 octane. Exclusively tracking at Gingerman Raceway this year, 2.2 mile course, 11 turns, top speed about 135mph, considered a bit of a more technical track but not overly so.

I'm an intermediate level HPDE guy after tracking the car a lot in my first season last year. Exit throttle is the biggest area for me to work on right now (I'm adjusting suspension parts but also wonder if we should address that with the dyno?)

To be honest, the dyno is more for comfort. If your logs are good and the tune is right then the dyno is really only for a reference point. Corner exit will be a suspension issue, things like 18mm rear bar o no bar etc. I had more problems with corner exit with 400rwhp then I do now with around 500rwhp.

I want to go to the dyno soon mainly to compete with @Fabman . Basically because we haver very similar engines and the same tuner. So its a great reference point to see If I got something wrong. or is if should look at E85 instead of race gas.

MH is spot on with his assessment of a dyno.......A dyno result will only confirm or show you what you're missing or have attained as far as the performance of your engine. It's a great tool for you to analyze.....................

Yeah, I think it's been tuned for 91 and 100 octane, not sure which it is set at now. Since the car is new to me the comfort I'd get from knowing it's tuned to my set up seems woth it, with a reference point to use as well. Thanks for the info.

You are doing HPDEs so I would also suggest setting the RPM range between 7400 and 7700, not the 7800-8000 many consider running in full race mode. This should encourage longer engine life and I have not been convinced cranking it all the way up to 8 bells is that productive.

Also, for MadChapeau, do not try and compare your Dyno numbers to Fabman's because his car is in North America , whereas yours is in South America. Logically, taking that into consideration, means your numbers will be down -------------------hehe!

Yes, my car has been run below 7500 for it's racing life, mistly endurance. Good advice though BP!
