Post your Dyno sheets.
Anything is welcome.
Bonus points: weird power curves.

Obviously not mine but it's pretty insane what the promod guys are getting out of an engine.

Yeah it might make 10 less hp than shown. Still gaps most cars.

Been thinking of taking my 2 stroke scooter to a dyno. I build it all up and would love to see sone numbers for it.
>>
>>28843805
Why does torque decrease with increasing rpm here?
>>
>>28844121
Volumetric efficiency.
my guess is a large, undersquare engine, likely a 1.8/1.9 Harley or something (117?).
Intake pulses, flow rate and cams set up for rock hard torque, but it simply can't flow enough at higher RPM. The torque is tapering off as the RPM increase, resulting in HP (torque x RPM) increasing up until a point.
Conversely, oversquare engines make little torque but rev to the moon with better flow rates and piston speeds.

Different strokes, literally, for different folks.

i drive a 25 year old tdi, my curves are pretty much the same as yours but with the power and torque switched lol

Boosted miata, been running about 15.000km on this setup now. Zero issues

Last guesses VVT? Wheelslip? If not then I give up.

If you’re talking about that vertical jump in the power curve I have no idea. I’m pretty sure they were using windows 95 or something lol, that dyno is from 9 years ago. It’s just an RB26, no VVT or VCT or anything.
>>
>>28844575
Yeah I was wondering how you make 50hp in 0rpm
>>
>>28844169
>simply can't flow enough
This means that the cylinder isn't getting enough air at high rpm because of the long stroke?
If so, would a large turbo fix at high rpm?
>>
>>28844721
A couple of variables but it's more or less the trade offs of torque vs horsepower, yeah simply cramming more air will increase to the power but won't change the shape of curve dropping off
>>
>>28844236
That one isn't but there are street legal promods in America. They're hitting 5's in the 1/4 and driving themselves from track to track.

Torque is the actual measure, HP is calculated off the number at 5,250 rpm.
>>28844496
Or this.

Nobody ran 5.99 this year.
