Yup. They're like a bottle rocket. There are only three settings: off, on, and burned out. Even liquid fuel rockets rarely have much throttle range (usually like 95%-100%). A big reason that SpaceX's rockets are so cool is because they can throttle the engines across a large range (40-100%), which is why they're able to balance the thrust perfectly for landings.

SRBs are just lit or unlit, and once you light them you can't shut them off. (There are a few rare exceptions where they can be extinguished early, but not the Space Shuttle's SRBs and I don't think any of those rocket motors are used in manned flight either.) In any case, it's completely on/off and they don't re-light.

In-car Alpha testing starting today. Bench and flow testing has shown very positive results. Over 80% of the pre-filter needs to be covered before it even starts to affect the flow. Significantly more filter surface area than OEM.

We'll be looking for Beta testers in the coming weeks and are shooting for a $49 price target if testing and feedback is positive.

Wasn't a good way to show flow, so I just took this pic to give a visual. This sink flows ~3 gal/min. These engines flow ~2 gal/min at maximum RPM.




If anyone has any questions or feedback, please feel free to post

I would likely be interested in beta testing. Getting my pickup and pan inspected soon anyway, in preps for the track season. Iíll talk to my local shop and see what they think.

Not looking to beta test, but will be interested once the pan spacer, replacement pan or whatever comes out so I hopefully only have to deal with it once.

Have been testing and riding the mule hard for almost 3 weeks, and it's been uneventful. Plan to drop the pan at 3K mile OCI and see how things looks. We did oil bench testing at over 300į so I don't expect anything exciting, but testing is mandatory.

Now is the time, if you'd like an opportunity as a Beta tester, please shoot us a PM. We are looking for those that rack up a lot of miles, track use, and uses the entire rev range more than regularly
