How does the turbo know which is which?


Well if you read through my post you will see my concerns about being able to rev the engine to "High" r.p.m.'s

So based on the turbo you reference, a 250 engine would have to rev "Higher" then the 292. So, IF (IF is important word usage here) it cost alot more money to rev these engines to 5,840, then the 292 MAY be a better engine of choice. ALTHOUGH, i would never pick an engine based on the turbo i want to run. I would pick the turbo based on my engine. BUT, if I had to rev a 250 to 5,840 r.p.m. to run a turbo to get me 300h.p., for example I might be getting in over my head.

I am asking questions to help me determine my powertrain setup, which is the beauty of starting with a blank canvas.

But thanks for being a smartass
