methanol direct port injection ... worth it ?
Look $3000 heads didn’t make more power on a 5.3 this proves 706 heads are better...
or use excessive amounts of water water on a low boost application and say look water injection doesn’t make any power.
You can’t go into a test with an expected out come and bias the test to prove your point.

He's running various tests, and giving you the results. There are no claims ? And not to forget....almost none of the tests shown are new. He's just reporting on tests already done, some months or years ago.

And don't think he's done a water only test ? Havent seen it if he did.
3400 lbs??? Lol...my GTO is about 3800 lbs with me in it. cubic inches and compression matter. Making a small engine act like a big engine still isn’t the same. Can it blow the tires off on the street well yes of course. Can it possibly run a faster ET assuming the car is setup correctly yes of course. ...but in the end it still isn’t the same as the big engine.
I think RH did a test of a small inch big block like a 496 or something vs an LS both NA and boosted. It was called something like boomer vs millennials or something. My issue with his tests are often the conditions are setup to bias towards the result he wants. The test was biased toward giving the LS the best chance yet the 496 still was way up at low rpm even though the dyno didn’t even start at idle.
Again that big block might need only a 2800 stall and still not bog on slicks at a prepped track while that ls is going to like at least a 3600 stall. That matters during street driving.

I would concur that if his testing was tweaked just a bit towards end user reality instead of the obvious biases it would be much better and meaningful comparative content.
I know he put a China gt45 on both, why anyone would use a single old tech t4 on that many cubes is beyond me but I did like seeing the back pressure log for both... thought he was going to do twin gt45 on the bbc but I have not come across it. The twin s480 on the 540 was nice and put out decent numbers for the boost but it was never pushed close to what those are capable of moving. That power has been hit with a built 6.0 and a single billet s480 to the tires.

I don’t know if I even made any sense...lol

And you don't need to push something to the point of destruction for the purposes of a test, especially when you've already proven any trends.
People seem to misinterpret testing.
You sure you aren't getting a little something on the side from Mr. RH? You certainly love to argue with anyone who has ANY constructive criticism.

I take the tests for what they are. Tests, along with results. Nothing more, nothing less.
You are entitled to do exactly what you said. Others are entitled to think exactly what they think; some tests are either biased or not actually valuable and interesting.
Because the test was less about engines, and more to prove the same turbo will behave differently on different engines. It wasnt to compare the two engines.
And you don't need to push something to the point of destruction for the purposes of a test, especially when you've already proven any trends.

The 540 files say it was on e85 and they did like 12.6lbs.... LOL I mean FFS you got +2400hp worth of turbo there and barely use half of it on a really forgiving fuel but then at the end hit it with a small shot of nitrous just seems rediculous to me so far as "testing" goes.
FYI Here is the twin gt45 454 test I could never find till today. Maybe the bias its just his character IDK but he talks about the twins vs single at the end, the problem is he is comparing 2 shyt turbos with horrible wheels and big AR and 1 great turbo being almost equal favor spool/response to the S480 on the lower psi tested lol. The real world comparison would be 2 smaller turbos with good wheels vs the S480, maybe 2 S366 or TC72, Precission 6766 etc. Just extreme ends to compare results from...

Yes he is comparing a lot of cheap ***** parts.
Because it seems that's what a lot of people want to use these days, especially here on Tech with all the China fans.. And for purposes of testing....it costs less too. So I guess why not ? He's not racing any of these, he's not using them in competition...he's just testing to see various trends.
Of course it would be great to see some back to back testing of numerically similar turbos....although that in itself wouldnt be such a great test on a dyno, as it wouldnt tell the true picture of what a turbo can do, or might feel on the road.

I did not think the test was about comparing the engines when it was done, but ya that is what his introduction basically leads into... The 454 was using a single plane I have no idea what cam but assume it was speced for that intake then barely revs to 6000rpm... instead of some type of ProFlo or RamJet intake. So to summarize the 454 was at its worst rpms intake wise and exactly where the turbo was doing its most efficient work. Talk about complete mismatch of parts and intended purpose, it just seems like an unrealistic comparison.
