theory's from the keyboard jockeys
LOL! That's me. Never had a wrench in my hand, put anything together, tuned or ran anything but my mouth.
If the results don't match the theory, change the theory.

I'd explain, but the IQ levels displayed make that sort of... pointless.

Sorry, have you made an extensive tour of my property and history? I began work on cars in 1963, were you there? I don't recall. My DD is a 520 hp twin turbo 2JZ-GTE Lexus. I started working on turbos in 1975 with a Corvair Corsa, then in 1978 with a new Riviera V6.
Remind me: when did I make any claim to "know everything"? Try limiting your insults to facts? Please enlighten me: exactly which statements of mine are WRONG (as opposed to "things you don't understand")?
You're up.

where consistency matters anyhow. Unfortunately true. In addition to all the other annoying variables (air density, ATF temperature, octane) you have to add intercooler efficiency (what's the actual output temperature?), time to spool, does spark retard kill more power than too rich (for the same degree of anti-knock defense). When you read that "on a turbo car the tune is worth 500 hp", that's what they're talking about. Poly you're a smart guy, but man can you come off arrogant sometimes. First... air density changes effect all cars, not just turbos. My guess is you already know that though. ATF temp effects all cars... not just turbos. An improperly sized trans cooler on anything is going to suffer repeatability issues. Explain to me how octane on a turbo car effects repeatability? Any car that doesn't have enough of it N/A or Turbo, is going to detonate and have issues. It's not a "Turbo" thing. Intercooler efficiency effects power... not consistency. Put a good sized intercooler on it, and you don't have to worry about heat soak. No different then making sure a NA car has the proper sized radiator. Time to spool is repeatable as hell. It's a mechanical device, there is no magical external unpredictable forces in the world that make it spool fast one time, and slow another. The mass flow from the engine is predictable, and that's what makes the turbo spool. I have HUNDREDS of data logs that prove it. My boost controller holds the boost within 0.1psi of the targeted curve throughout the run. It will go from 13psi to 20psi in about 0.3sec. What does spark retard killing more or less power then A/F ratio have to do with bracket racing? It's like any NA car. You get a good tune in it, and leave it alone when you're bracket racing it. Who would re-jet or move spark around in between rounds at a race? If we're going to focus on facts... I have 100's of passes, timeslips, and data logs from a turbo car that I actually bracket race. You're up.

Time for a group hug. You wonβt find a stronger proponent for turbos than I, but .... If I were building a bracket car, it would be either N/A and light,(choice #1) or turboed and heavy (choice #2) A turbo car that is light and at its limits will repeat easier than that same car turned way down to meet an index. Results may vary...

Stupid turbos.
I got runner up last night π
I treed him and out 60 foot him with my new best 1.14
He drove around me. I make 20 PSI on gas. His Procharged BBF on alcy makes 38 PSI . He got me by a car. Running heads up? Or couldn't run your dial? I wouldn't bring a knife to a gun fight.

After YEARS of reading Poly's posts both on here and elsewhere, there's no doubt he is a thinker and very knowledgable in this caper.
But seriously....his choice of words on forums are perhaps a little abrasive and can be processed as a form of arrogance.
All of us have knowledge some less than others however projecting oneself as the last word is really unnecessary.
We all want to learn as much as we can....without the aggravation.

Yes, it's only helpful if you tell people what they want to hear. Anything else is just sooo hurtful.
