Check www.ststurbo.com they put it away from the engine. I would think it would have a big turbo lag. (IMG:style_emoticons/default/huh.gif)

Well, that Crown Engineering drawing brings back some memories, for sure! That's the one I had on my '73. Yea, I never liked that boost controller either. I found it better to control boost with mild exhaust restrictions if the turbo was sized properly.
Keeping boost around 6-7 psi is a nice balance between reliability and performance, IMO. As you go higher, the diminishing returns of stressed components, spark timing management, fuel management, etc, become extraneous requiring a purpose built motor. Those high boost Japanses motors were built to take it from the start, along with the appropriate management systems and intercoolers so the comparison is apples to........ Sounds like Jake has done some TIV turbo work; nothing like experience to get a real handle on things. Also, don't loose sight of the fundamantals. No lag at 3000RPM? RPM doesnt matter nearly as much as load. If you were travelling down hill at 3000 in a no load condition and nailed it, you would get lag. I'd look at some type of bypass valve to help on-again throttle response. FWIW. Andy |
