I too believe 350 is plenty, because if you look at it mathematically, it only takes 325 cfm to turn a 225 cubic inch motor @ 5,000 RPM if the volumetric efficiency "were" 80%. 500 is just adding...

Well, with an absolutely "stock" slant 6 the timing should be 0 initial while idling, and 32 advanced at "All in" with no vac advance hooked up with a 1 barrel Holley Carburetor. On that setup I went...
I think I have a theory as to what can be the issue here - I recently changed the "boost" gauge to a "boost/vacuum" style and notice i only get 10 inches of vacuum under idle. I tried adjusting the...
I initially had the turbo mounted with a huge exhaust leak that ran at 0psi, and the turbine barely spooled. Basically my old wastegate leaked like no ones business and no heat or pressure seemed to...
I hadn't even thought of the valves floating like that. I believe the valves are stock replacement. When I had the head rebuilt the machinest put in new valve springs, new valves and seats, and...
Sorry I couldn't log on to Turbo-mopar for a while. Was the site down or something?
Anyway. I changed the gap down as suggested and it seemed to help a little. I closed them to .023 and tried...
mine is the larger slant. 225 cubic inch. I've not heard of others having issues under boost like this using the same manifold. A lot of people move straight for the 4bbl carb intake though, wheras I...
Yes, on boost the vacuum advance completely drops off leaving it at 18 degrees. This is limiting as you say but pretty much everyone I spoke to that has done their own slanted turbo has agreed that...
I have been working for the last 4 or so months completing this project. I turbocharged a slant six in my 1968 Dodge Dart. I have literally built the entire setup in the driveway.
I am searching...
