oh wow I didn't realise it was the entire prop that came off I figured it was just an entire blade

[@michaelgideon8944]

what is going on with all of the vapor cloud coming off the turbos? Are they into the surge area of the map?

[@SaltyBasshead]

Seen quit a bit of water that was ingrested on the driver's turbo right after start up. I thought that was the issue then BOOM. Bye prop

[@danw2112]

Didn't someone dive to the bottom of the river to retrieve it a day or two after the races?

[@AntonioMorales-xf3oy]

The propulsor, how many HPs????

[@lelandlewis7207]

I've read that it is capable of 3,000HP.

[@bryanst.martin7134]

Is there a rev limiter causing all the pops at the turbo inlets? Or are they misfires?

[@tyronetrump1612]

rev limiter

[@bryanst.martin7134]

@@tyronetrump1612 I would put a barrier between the turbos so that one popping doesn't necessarily affect the other.

[@aliciabrowndocken4660]

What's the reason for all of the Compressor Stalls.

[@IsegrimSTP]

My best guess is that the radial Airflow coming from the bow of the boat creates a low Airpressure area inside the intake of the compressor causing the blades which are in the most forward position of the boat to tipstall which causes a full stall almost instantly. You can see that because there is always a small condensation cloud forming prior to the stall on the bow side of the comrpessor intake,.

[@justachipn3039]

@@IsegrimSTP Info says the "PROP" came off... nothing to do with the motor. Intake air cons up on turbos... seen it lots of times.

[@tyronetrump1612]

Not compressor stall - he is bouncing off the rev limiter and you are getting the intake charge blowing back thru the cold side
