I will just add that no, valvesprings will never add power unless there is a problem with them and the ramp rates of the cam you are using. And there is no problem with the valvesprings stock with stock cams, so no power to be gained there.

So, the power gained is via upgraded stock TD04 turbo, intercooler and piping, no cat, K&N drop-in filter and a tune. But that is hampered by too low of octane fuel availability.

Good to know all around. Pretty much validates my own and a few others calculations and observations in regards to the LTG. If you had fuel like we do in the states you would probably be around 10-15hp more.
Will not arguing with you regarding valve springs, but hope it works.
My best result was 380 hp and 693 Nm, but on such spec detonation of fuel was too heavy and we decided to deforce a little bit.

So the claim is 380 rwhp, and 511 ft lb? Is that correct??

Actually, he stated that was too aggressive.

But on the first page he stated 372hp and 494 ft/lbs.

It also shows stock was 236hp and 289 ft/lbs.

Very curious how the math breaks down between these two dyno graphs if someone is capable of doing that accurately!!

The conversion is:

ft-lb =Nm * 0.73756

Ultimately, I think the Russian dyno is juiced heavily in the torque department and somewhat in the HP department compared to dynos here in the States.

I means 236hp is a little high stock and 289 ft/lbs is a bit higher than stock. Now, did he already have a gutted cat at that point???

If so, the 236hp is "within range", but the torque still seems quite high.

I will add that dynos can represent whatever anyone wants depending on how you set them up and calibrate them.

So, in reality, doing comparisons of different dynos has always been somewhat worthless outside of looking at the general curve and determining how "believable" that representation really is.

Russian version of 2.0 engine is reduced to 238 Hp to pay less government tax, that is why stock graph is clear. Also, russian Hp is on a flywheel, US normally on wheels, am i right?

Yes, US dynos are at the wheels.

If Russian dynos are at the flywheel, how do they get "accurate" given driveline losses?

Seems like a lot of supposition to try to come out even fairly accurate.

That also makes the dyno read of the HP completely believable at 372hp.

There are some kind of accurate coefficients for each car with drivetrain losses.

Just subtract -20% to what is showing.

Stock - 189HP/232TQ
Mods - 298HP/395TQ

Torque still unbelievably high. But this sound more like it to me.

Actually, aren't driveline losses for the Camaro more like 14%?

Given efficiencies of modern "optimizations" I didn't think a 20% figure applied anymore, even to AWD vehicles (even those are closer to 16-17% with nothing higher than 18% for most vehicles).
