is there supposed to be water exiting engine? i have a 71 evinrude 60 HP serial:C 94256 Model:601730 just had new wtr pmp & impeller replace-cant see any watr when runing-does it have to be hot and allow for thermostat to open first?-i have muffs on with the tap-(front of the engine -bottom end over the holes?) should i take it to the river and try it there-as there is another hole on the upper portion of the lower end (above the split where the bottom end comes off) also why does it idle rough and skip…
So I do Formula SAE- it’s a student design comp and we build a car and it has to pass a gazillion technical inspections.
One of those is passing sound- the car has to be under some specific decibel range I think 117 or so. With single cylinders that’s pretty hard. When they made a tweak to use DBC instead of DBA it really rekt a lot of teams one year.
You can decrease sound by doing acoustics on the intake/exhaust, adding more exhaust line, or packing the exhaust. We had exhausted those options and still couldn’t pass.
There is a fifth option. Lube.
I don’t mean like engine oil or grease. No. I mean sexual lubricant. The stuff you put on ya dick. Ya put it up in your exhaust.
We hear about this from another team who’s pit’s next to ours, we borrow some of theirs and try it. This stuff works; we dropped a full dB or so, enough to pass sound.
This stuff smells GODAWFUL when burning out of a muffler.. It also makes the exhaust smoke. In cold weather it looks normal. We’ll get back to this.
That was michigan, aight? In like May. We go out and get more lube for the comp at lincoln. Apparently we sent like 5 guys and a girl to a sex shop and we buy two kinds- a very generic nondescript brand… and strawberry penis arousal gel titled “DICKALICIOUS”. I’M NOT MAKING THIS SHIT UP.
Let me tell you- shelling out the extra cash for the strawberry made all the difference because A) it drops more dbs and B) THE EXHAUST SMELLS LIKE F******* STRAWBERRIES
Now in the warm, an exhaust shouldn’t put out smoke. We got flagged down because they thought we blew our engine or something. We had to explain to them that we lined our exhaust with lube. This apparently is not that widespread of a thing. They didn’t believe us, so we grab the dickalicious and show it to them. They’re just. laughing their asses off. And we ran like that the entire comp!
And the moral of the story is: lube makes things quieter, and higher quality lube is better. And strawberry lube actually tastes like strawberries.
Further Aerodynamic work for the 2011 UTS Motorsports vehicle. I spent a lot of time trying to get as little drag as possible, while also making sure there was considerable flow to the rear diffuser, making the undertray as efficient as possible.
A quick picture of the aerodynamic work I did for the 2011 UTS Motorsports vehicle. The aim of the project was to reduce vehicle drag as much as possible, without influencing the vehicle design too much. I also spent some significant time looking at cooling efficiency and diffuser efficiency.
Found some photos of CR-17b (aka my new project) in action. Definitely not the best car we have ever built, but still a race car. It ended up being a two-year car due to some team issues. That’s kinda how I ended up with it. Still should be fun. Lot of redesigning to do still.
UTSM11 specification graphic. I was design lead for this vehicle, and its almost finished. 4th vehicle I have been the design leader for, so it should be pretty special once its on the track. I cant wait to drive this car.
my capstone project, building a turbo setup/engine package for SLU’s Formula SAE team. for those who dont know, FSAE= small open wheel formula cars, 625cc is the max engine size, and all air must flow through a 20mm restrictor (smaller than a nickel). Turbo rules require the throttle and restrictor to be in place before the compressor.
currently building this engine package for the nonexistent 2014 car, the shaft at the back will mate up with Ranken’s normal engine dyno, the blue peice roughly simulates SLU’s eddy current dyno.
engine stand will be finished up in the next 2 weeks, fabrication of the turbo stuff starts during christmas break
