I'm glad you realize that
[quote-Davesdeville]I'm not saying a 454TB is necissarily a bad idea, just that it may not be worth the effort to buy & install. And you're right it's 450ci worth of air, but it's still packed into 300ci worth of space.[/quote]
The 4.5 liter TB might be a good choice to begin with. I have like 5 of them laying around ready to be installed.

If you use the efficency numbers and calculate out how much more air is actually going into your engine you can have an incredibly rough guess on how much fuel needs to be injected when. But you'll still be guessing for the engines true volumetric efficency, when the turbo will spool, how much boost it will produce at what RPM, along with other variables. So you definately still need a good amount of leeway for fine tuning. Have to make sure you have that room to tune it with whatever fuel management you go with. |
This is why I prefer the Megasquirt method or something like it. I can add an auxiliary fuel system on top of the stock system. It should allow for that all-important fine-tuning. And yes Cap_Fiero, it does facilitate tuning for boost.
The reason I wanted the compressor map done is to see if it might be able to help me in figuring where the boost starts so that I can tune for fuel and timing lead. As for now, it's just going to be trial-and-error for figuring when to add the fuel. With the MS allowing for 2-bars, I might not have to get too technical on the tuning for fuel...
