RJC Power Plate Dyno Run

Here is a typical example of what we see when dyno testing the plate. The blue “Dynorun.002″represents a dyno pull without the plate. The Red “Dynorun.005 represents a dyno pull with the plate installed. These runs were taken back to back without any other changes other than the addition of the plate. This was WITHOUT increasing the boost . We see greater gains in HP being able to increase boost pressure because with even airflow distribution the knock threshold is raised Typically 2-4lbs. This means the real gains come from being able to increase the boost pressure without knock.

RJC Racing Power Plate Track Testing

Test #1
1987 GN stock long block, TE-44, 15 row stretched Stock location intercooler, 009 inj. 4500 ft. ele.
We made 3 baseline passes with the stock plenum at the maximum boost that we could run with the gas we were using. We were running VP C-16 The baseline runs were made at 26# of boost. This was the most boost we could run as we had 3-6 deg knock retard every run.

We then installed the AD Power plate and made 4 more passes. Turning up the boost each pass because we had no knock.

On the last pass we pushed a little through the lights so the clock started before we let off of the brake.

Since we first tested the plate we have tuned an additional three and a half tenths out of the E.T. The car now runs consistent 11.80 at 114 at the same elevation with no other changes.

Our conclusion with real world testing confirmed what we were seeing on the flow bench. The Power plate maximized the airflow to all cylinders. Remember you can only run as much boost as the weakest cylinder will allow. This plate allowed us to run 4 more pounds of boost than with out it. Which in turn gave us almost 3 tenths reduction in E.T. and more than 3 MPH.


Test #2
I have tested it on my personal car, an 87 GN with extensive modifications. After installing the plate I made 4 passes they were all in the 10.60-10.65 range. This was at about 22-23psi. I then took the plate off and made another pass, 10.76 with identical 60′ as before. This was the slowest pass of the day by .11 of a second.


Test #3
The GSCA “Buick Grans Sport Club of America” did back to back tests at the 2002 GSNationals in bowling green KY. Their test neted a 2 tenth reduction in E.T. and a 2MPH increase in 1/4 mi times. This was without increasing the boost pressure. How you say? The test vehicle was experiencing slight knock without the plate, once the plate was installed the knock retard was gone and thus netted the 1/4 mi results.
