Probably a very accurate statement, dawg.

In fact, for reasons associated with leaning out, erratic fuel pressures, and even detonation, I had to change all of the above or add something to the equation that I've ended up passing along to the board in some manner or form.

Many people who have been here for a long time know I was one of the first generation of people to turbocharge. I made my decision back when STAR had just come about, and Wyatt had turbo'ed his car maybe 3-4 months before I did with one of those early STAR kits. I was probably a month or two behind Corbin, and perhaps a year or longer behind Murix and Joe A. So for all that's worth, I've been turbocharged since the summer of 2000. We probably had like 5-10 people on the board TOPS that were turbo'ed.

I've accumulated over 35,000 miles on the stock internals, and had a couple of bouts of detonation and leanness due to different instances of a bad Cartech and failing HRC fuel mappers. But after changing out FPR's, and the last year, switching over to the 8 injector setup, it's been nothing but smooth sailing. (Thank goodness for all of Corbin's tireless quests for seeking better fueling systems, so I could follow his lead.) I probably post to these sorts of threads each time to try and dispel fears of people blowing up their cars for merely adding a turbo kit.

Those of us who've been here for a while, KNOW the classic story of why 420a's blow due to boost. It's almost always the same, and can usually be easily pointed out; OVERBOOSTING due to the owner's attempts for more power without having anything but a FPR, or due to some problem with a wastegate or boost controller.

I concur Dino's thoughts about these engine's ability to hold large amounts of boost. Even the old turbo Mopar's hold 20 psi of boost on their stock internalled rides, but I think are more careful with their tuning and fueling than many of us are/were (even though their internals are more stoudt). I'm of the opinion that someone could probably reliably hold 12-17 psi pretty reliably if the fuel was there, and the timing could be pulled back on the top end.

The problem is, most of tax those little 235's WAY too much.
