I found this video. It looks like it is slowing the car down. But with electric the wheels do a lot. I imagine I car with a break is different.

Awesome to see drag racing picking up in popularity. Doubly cool to see you build cars with nitro power!
Just personal opinion but I would ditch those fancy canister air filters and go with open 2 stage element filters.

Designed some shock towers. Considering 3d printing the bulkheads as well for the chassis' I sell.

Car got it's initial runs. Had some concerns when warming up, the car was spinning badly, like a top, and at one point it did a corkscrew cartwheel (nothing got hurt thank god).

I made six or seven passes, and the car actually ran straight and true. I recorded a couple of 2.8s runs. A couple didn't get recorded because it was a bit windy and the little shrouds moved that block light from the sensors (Note - need to either screw or tape them in place). The run below might have been a bit faster than 2.8, not sure which one this was. All the ones recorded were 2.8 though. I didn't do any fine tuning of anything - this was just fire it up and go. I really just wanted to make sure it would.

I replaced the shocks with the same kind that I am using on Incinerator, that are big, big bore and much better to adjust - plus only 30 dollars for the full set. They aren't quite as good as the Integy ones I use on Invader, but they'll do just fine.

Got it balanced on the corner weight system, and then took it out for a few test passes. Made some adjustments to the throttle linkage and trans brake, and focused mostly on 66ft passes for seeing how it was launching. I already know what it can do on the top end.

It's definitely imperative to get the LSN right when using a trans brake. If it's too rich, the engine will get loaded up, and bog a little on launch. When you get it leaned right though, man, it's like shooting it out of a slingshot. (I already sense being told I can't use it at some events).
