I've heard conflicting opinions on the 243/799 which is why I said what I said at the end.
There is tons of conflicting info, but if I have a choice for over 800hp with boost, then 243 it is.
I like Holdener and he has some great info, but he won't lean on anything. And I don't know why - I've asked in his live chats and he always offers up a canned answer. I'd beg to see him lean on that Summit S475 and the VS7875 until they give up to see how far they can go in terms of boost, but he never exceeds 20psi. In the closed environment that he runs them in you could draw some real conclusions about compressor maps, IAT's and power. It would be even better to include some EGT readings at the same time.
He proves an awesome, and very often misunderstood point, the more power you make NA, then more you'll make with boost. He's proven that every which way but Sunday lol. I loved his cam test as well - every cam was virtually identical despite all of the claims by the grinders. I'm confident that he never completed the turbo portion of the cam test because he would've lost sponsorship or standing with many of his suppliers/contributors. Brian Tooley and Comp don't want to see a budget cam (Elgin 1841) from Amazon that is 2/3rds the price keep up with their custom grinds.
The most disappointing video was big bang 6.0 that they were going to run until it didn't. But he stopped because he ran out of MAP sensor - it was pathetic - I think I yelled at the computer lol.LET THE HOLLEY TAKE OVER ?????? Let's see what Mr. Holley has to say dammit - push it off the MAP and let it self tune, it would've either worked or it wouldn't have.
FWIW, I'm still glued to most all of his videos. I'm anxiously awaiting the 3800 stuff.
The best part of LS heads is there isn't a bad one. And for something that isn't a dyno queen or max effort build, then you aren't giving up much in stock form.
