You should always check the timing on a new engine first. Then you can eliminate one thing at a time to cure the problem.

Chris,

Your exactly correct it probably would build boost. I’m just explaining that when they are properly sized they offer the best spool up rates, peak boost, lowest exhaust temps and acceptable backpressure.

This is a perfect example, when you see those turbocharged Toyota Supra’s cars drag racing with their small displacement with their high RPM engines and big dyno numbers. The turbochargers they use are so large that if they were placed on a much lower RPM, large displacement diesel engine they would put out roughly the same HP, if everything else was matched properly.

A turbocharged 600 cc motorcycle engine, redlining at 15,000 - 16,000 RPM. Needs “much” more air than a 1,434 cc or 2,868 cc engine operating at 650 - 1,000 RPM.   

As I mentioned in the other post, even if a turbo was over sized it would still lower the piston and exhaust temps from the boost produced. It just wouldn’t work correctly without proper sizing, because an AC generator needs tight regulation.

A too large of a turbo with the required lower compression ratio, makes for an engine that is much less responsive and capable of following a tight RPM zone, compared to a higher compression, naturally aspirated engine.

By just looking at it without exact numbers of size, it just much work fine with the Listeroid engines. My gut feeling is it would work.

Turbocharger size is directly proportional to peak horsepower output, if that turbo can handle 125 HP then it is "Oversized' not "Undersized".

When we set up an engine for drag racing we put a large turbo and for street use we use a small turbo. A low RPM generator needs an extra small turbo to provide adequate and useable spool up rates.

There is not much air flow from a 650 - 1,000 RPM engine, even though they have a fairly large displacement.

Turbine housing size is also a main factor, but properly matching turbo size with peak HP rating provides the best overall match.

Tom,

In my opinion, you made a wise choice. Outback inverters are well made and the military uses them for their small systems. They don't like all the bells and whistles, the more basic an inverter, the more reliable.

Outback inverters are expensive per watt, but they spend the money on good quality internal components and they are beating Trace at their own game. That is one of the reasons for their loss of market share over the past few years. You’re going to get years of trouble free service from those units, good luck.

Tom,

There is also a Equalizing Batteries Mode to keep your battery bank in top condition. Also, there is a Selling Power - From a DC Source Mode, my 5548's had them not sure if your 2512 has it. It enables the battery bank to stay fully charged and sell the excess power from an engine driven DC/solar/wind/hydro source, back into the grid. It also has a Selling Power - Stored in the Batteries Mode, to sell what power was produced that day, back into the grid. I loved the Trace inverters with all their options, what I didn't like is that, they don't last long before needing repair. I went through 2 sets of 5548's before I gave up on the Trace product line. Some love them and some don't. When they work they are great. I hope yours last along time.

rocketboy,

It sounds too advanced to me also.
