Brutal Big Block Nitrous Camaro hits the Dyno 

I agree

I'd love to see that monster of a Rat motor on an engine dyno.

I think it's 15%, not sure though, I usually hear that a lot. (I'm 16 and trying to learn more.)

Robert Rice First off glad your interested in Motorsports!!! I’ll try to be succinct, but there’s actually a LOT that goes into drivetrain losses and they are usually not a straight percentage (non-linear-relationship) even on one vehicle, it changes with what gear your in, vehicle speed and how much torque the engine is producing, as well as a host of other factors.....in this example the original commenters 25-30% is very realistic and honestly it could be even higher than that, not knowing the cars particular setup, but I can give you a few reasons why it’s that high......in no particular order of significance, bigger tires act like a lower numerical gear ratio compared to the dyno rollers diamater therefore the mechanical advantage is less, the next is big tires physically weigh more and store greater potential energy via. inertia so there harder to spin-up and slow down, next tires (of the bias ply drag slick type) deform a lot on the roller and this increases friction in the tire itself but also allows more slip on the dyno because the contact patch is now at different diameter than the tires rolling diameter so it has to skid, next is with tires that large the rear gears in the differential are probably a pretty high numerical ratio so again the larger difference in diameter between the ring and pinion contribute to greater friction, then we get to the big lest contributors to a low power %.....a car like that with a radical engine and nitrous will have both a high “stall-speed”, but also “loose” convertor, so it leaves the starting line making enough torque (at a high RPM) to get the car moving rapidly, but doesn’t transmit too much torque, so when the nitrous instantaneously adds a huge amount of torque that the tires don’t immediately start spinning, to maintaining traction; all this contributes to the convertor that reaches it best efficiency at max RPM (redline) where your already on the back side of your power-curve and torque is going down....therefor you may be “missing / not recording” 30% of its power at the max hp RPM and 15% at redline, but you could be losing up to 50% near the stall speed.....so like I said in the beginning the original commenter is probably pretty close in his estimation, and the crankshaft HP could be easily around 1300-hp.....hope this helps get your gears turning.....keep studying.

@@ericschumacher5189 Thanks for the lesson man, I'll keep studying. 👍👍

trunk thought it was really going that fast.

Lmao

I explained it and detail my 69 the same way it just looks like a 67. I got whatever parts I could during the build. It confuses me sometimes

1044 ftlb torque

You can see in the video that it made 1,120lb of torque

@@GreatestHITS26 my bad

@@foxxrider250r it’s all good

michael anderson and 67 have round blinkers 68’s have oval blinkers in the grill

Correct

68

Not making excuses for the 2JZ, I picked this Camaro to win, but it was a dyno contest, not a drag contest. This car would kill that 2JZ's super narrow powerband and lack of traction on a strip for sure.

Twobarpsi This car is actually pretty slow for what it is (no hate) Outlaw 10.5 cars are now banging on the 5-sec door, and had to run mid 7's just to compete 15 years ago - this one runs 8.0. A REAL 10.5 Outlaw car would have pegged that dyno at 2500 -

Malicious SRT That may be true, but it would still beat the 2JZ in a drag race. 2JZ's are notorious dyno queens.

Twobarpsi I never said a 2jz would win anything..

Yeah I know, I was just reinforcing what you said in post 1.
