Quote: It is probably the load on the engine that makes the boost.
Your engine is turning a LOT of rpm at highway speeds and yes, turbos LOVE load just like the top fuelers. I kept lowering the rear transaxle ratio and the car just kept going faster and quicker.
Reliant runs a 2.50 final drive ratio and loafs through the lights at 5200-5300.
Daytona was 3.85 but it had overdrive at cruise, off the top of my fuzzy head, 2500 rpm while going 65 sounds about right.
Feets was your Shelby Charger with stock or near stock exhaust? Chrysler used the cat & exhaust to limit the turbocharger, Daytona had a 3" system.
