1971 Gold Metallic Project, The Turbo 1.7 Options

[McMark]

Current Status:
Running great!

I picked up this car late 2012 with the intention of flipping it. But never got anything done on it until I tore apart my Marathon Blue Metallic 73 to prepare it for WCR 2013, which of course didn't happen. So now this Gold Metallic 71 is my new driver.

Starting off at the beginning. Trekkor found the car and had it for sale. I picked it up from him without the engine, front bumper, rocker panels or wheels pictured below. Otherwise this is how the car came to me.

Well, 600 miles under my belt and no major issues to report. The laptop stand was PERFECT! I didn't have to do much tuning, but my CHT sensor took a dump and started reading all over the place, which caused the Warmup Enrichment to come in at random times. This would cause the engine to miss as it went rich for a millisecond. The TPS was also popping Accel Enrichment periodically, but I solved that by changing the TPS Lag Factor to 40 (was 50). This let the ECU ignore the periodic spikes that are occurring for whatever reason.

Overall I'm REALLY happy. I still have a little pinging when I try to go WOT, so I just kept throttle movement to 50%, which wasn't an issue because I just wanted to make sure 'normal driving' was working well. I'm only getting about 5psi of boost, but I'm pretty sure that's how I have the wastegate set. Boost comes on between 2500 and 3000 rpm (can't really test that without WOT runs). But in this 'normal driving' scenario there is pretty much boost whenever I want it.

Power feels a little higher than a 2056, and I suspect that once I can dial up the boost to 9psi or so, I should be in 2270 territory or beyond. Pretty good for a 1.7. Driving impressions are fantastic. Most of the 600 miles was between 70 and 80 mph and even at those speeds I could ease on the throttle to pass or climb hills. Under day-to-day driving conditions, I'm completely happy.

Hit stop and go traffic coming into Portland (and rain (IMG:style_emoticons/default/dry.gif)) and the engine didn't miss a beat.

Now to go hang out in Portland.
