Totally Stock RX7 Dyno Numbers are in and I wasn't disappointed

Note: there is a typo at 3:58. The bottom series is supposed to be a series 8 99-2002
First Dyno video to get a baseline of my 94 Efini RX7. The goal of this series is to demonstrate what one may expect after adding each additional part to their Sequential FD RX7. I first completed all the maintenance and confirmed proper sequential operation. This was to assure we had a healthy car to test on and that it operates as it would have as if it had just off the showroom floor. Restoring the sequential turbo control system can be found here

The Dyno being used is a Dynapack located at Full Detail Automotive
@FullDetailAutomotive
I plan to use the same dyno for each session so the comparisons will be as accurate as I can make them aside from weather conditions.

I'm honestly surprised a shop that deals with FDs so much doesn't have a better fan setup to try and approximate real world conditions. That fan is probably providing less air flow than driving along at 30mph.

That is on my list for the next sessions. Already have a friend that offered to send me with a high volume unit that should work.

The stock intake ducting is too convoluted for fan speed to make much difference. Instead of depending on forward motion to keep the intercooler temp down, I wired in a small SPAL pusher fan that runs full time. Even the stock intercooler can do a pretty good job with air constantly flowing over it.

@F1aficionado that's my plan when I upgrade the SMIC, I don't want to spend the time and money to do it to the stock one if it's getting replaced

​@@touchedbyawankel It would be interesting to see a comparison between fan supported stock and aftermarket SMIC and an aftermarket SMIC with no fan support.

@@F1aficionado Convoluted? No difference? I'm guessing you've never seen it out of the car, it is a very simple "s-duct" It's a fairly well designed duct given the space constraints of the early design. It looks a lot like what we see in aerospace, or what you will see in motorsport. Honestly, the biggest issue is the airbox sharing an intake with the intercooler. The 99+ revision gives the ducting more space and another air intake for the actual inlet so it isn't pulling air that could go through the intercooler. With the stock early design especially, air speed makes ALL the difference, not no difference as you claim. The duct is placed in a high pressure area and the underside of the car is a low pressure area thanks to the under tray but you need air speed for a pressure differential. By using a big low velocity fan that is woefully inadequate to represent road conditions, you give the ducting zero chance of doing its job. RX7s weren't designed for drag racing or dyno pulls, they need to be moving forward for the engine or charge cooling to work at all.

So my estimation wasn't far off on Reddit
