Serious Dyno testing underway!

As we work to put the finishing touches on the EFI system I have decided to take a very thorough adventure through the Pinz engine to find out what it's limitations are and what settings it really likes best.

Right now we have been testing a Carbureted engine 100% bone stock, the plans are to test it as is 100% original and then start adding enhancements like the K&N air filter, civilian conversion, pertronix, a different muffler, a set of purpose built headers and compare all these with different fuel ratings and timing/jetting changes before ripping all the carbureted parts off and installing the EFI for it's comparative analysis with the same outlined changes made.

The engine is on the R&D dyno in my lab now, I'll be posting pics soon!

That's great Jake. I know that innovators such as yourself, Jim, Scott, Andre and others spend a bunch of time and money trying to perfect modifications that the rest of us can use on our trucks without having to go through the "trial and error" process.

I look forward to hearing the results. BTW, is there going to be a fuel consumption evaluation with these mods as well?

My dyno measures both the brake specific fuel consumption as well as gross fuel use. I plan on doing extended run, steady RPM tests to measure and plot the differences.

I already know from personal experience that the EFI gets much better MPG, since it can maintain much better fuel atomization and can remain cool running with higher air fuel ratios.

I just finished testing for the day and will post my best bone stock graph later.

Jake for what it is worth, the K&N filter is a piece of crap. In an off road environment it allows too much particulate matter to pass causing scoring of the cylinder walls(experience is the best deterrent)

Also they tend to twist and collapse in the housing(have removed several this way

Good to hear you have made progress, rock crawling is so much easier with injection

I didn't like the construction of the KN filter at all and I figured it would not filter as well, but its simple enough to swap if you plan on doing serious highway miles. My Pinz sees more highway time than off road and I have found with EFI that the system is seriously limited in it's performance by the stock filter at mid range engine speed.

The purpose of what we are doing is to establish base lines so we can forecast what the users of the system will experience when using various accessories and enhancements with the EFI system. The onlt thing that matters to me are numbers, be it temp recustions, efficiency benefits or broader more usable power- it is all in the numbers and right now I am watching 28 channels of what the Pinz engine is doing- thats 15 more channels of data than a human is connected to during open heart surgery, FYI..

My main objective is to retain and enhance the down low power as well as broadening the entire powerband and flattening the TQ curve higher in the RPM range- this will make the entire engine better, whether you are rock crawling or running 70 MPH on the freeway.

Wow, I know this is a huge effort for a small group of owners compared to the VW crowd (which I came from). I for one am extremely interested in any work you do on the headers and exhaust systems. This is one of my near future upgrades and an area I think is not developed enough. I'm sure eventually, I will be a buyer of the EFI system in the future- if you're still selling them. Thanks again

Of course- I come from the VW and Porsche aircooled world as well

What I have found with the Pinz engine is the same thing that I found with the VW Type 4 engine when I entered it's dimensio about 15 years ago. The realm is vastly undiscovered with no real base line data available, making it very hard to see what an enhancement can actually offer the engine/vehicle.

The same things I have done to date with the Pinz, I have also done with other engines I have developed in the past. The Pinz is the simplest engine I have ever developed, thats because it already has the most robust design and is well "over built" from the factory internally and only needs induction/exhaust/ignition optimization to be an entirely enhanced engine.

By the end of next week I'll have all the data I need
