Re: 1400 hp Big Chevy combinations
I think you are correct... pd superchargers and nitrous must put much more stress on components than turbos... the video of the big block is a great example... that engine would have needed a 400 hp nitrous hit... I don't think the cast pistons would have survived.
Re: 1400 hp Big Chevy combinations
Yes, that engine has cast pistons, stock rods, and was only running 12 psi.Dave Koehler wrote: ↑Mon Jan 13, 2020 7:48 pm You do realize that 1400 HP is 56% more than 900 HP?
Let us know what the cost of the parts and mods in that video comes out to.

Just a quibble point on stress. Cylinder pressure is cylinder pressure regardless of the method used to achieve it.Craig J wrote: ↑Tue Jan 14, 2020 10:56 amI think you are correct... pd superchargers and nitrous must put much more stress on components than turbos... the video of the big block is a great example... that engine would have needed a 400 hp nitrous hit...

Re: 1400 hp Big Chevy combinations
There’s the peak cylinder pressure and the average cylinder pressure. I think that compared to NA, turbo engines have relatively higher average of lower peak cylinder pressures.
Which big Chevy has the heaviest and lowest compression cast pistons? In a whole another application, we’ve had good luck with heavy cast pistons with low enough compression and a wide enough piston ring gaps.

Are you sloppy mechanics?

AIN'T GONNA HAPPEN. A 6k budget isn't even remotely close to that, supercharged or not......1400 hp isn't a joke. Especially if you want it to live....Add into that about 500-1000 or more for a day or more on the dyno to get it sorted out too.....
Save your money...wait until you can actually afford it.....
Just curious if you have seen this video, or know about this car:
With $6k you're relegated to a stock, worn out bbc and 2 worn out turbos. 1400hp?
Ahahahabahahaha.bullshit.

Re: 1400 hp Big Chevy combinations
So you think it would be better to start with a 6.0 ? That seems a bit strange, I really thought the the extra 2 liters of displacement would make it easier to reach the goal... Interesting idea.
Re: 1400 hp Big Chevy combinations
i disagree, tear down an engine thats lived on a turbo for a while and tear down one that made the same power on nitrous, and its clear the nitrous is way more abusive. the amount of juice required to meet his budget 1400hp will likely result in an oil pan full of parts.Dave Koehler wrote: ↑Tue Jan 14, 2020 11:08 amJust a quibble point on stress.

Re: 1400 hp Big Chevy combinations
I doubt you will have a 4 bolt head deal work at that hp level but maybe. Copper gasket with oring groove and high tensile studs. It wont be cheap either to do all that. Stock crank is marginal at that power level they tend to move around abit. I mean the big bang stock bottom end 6.0 record was 1500 odd hp flywheel but thats a dyno pull not a full track pass.
More reliable and realistic is 1000-1200 hp.
Either way unless you get parts for free and do your own machine work i doubt you can do it for 6 g. Efi would be strongly recommended and that adds some cost. 1000$ in injector and software on stock ecm stuff. But you probably would be better off with a megasquirt or holley

You are saying that the nitrous is more spiky (a word?), detonation sensitive or creating higher pressure than needed.lefty o wrote: ↑Tue Jan 14, 2020 12:31 pmi disagree, tear down an engine thats lived on a turbo for a while and tear down one that made the same power on nitrous, and its clear the nitrous is way more abusive. the amount of juice required to meet his budget 1400hp will likely result in an oil pan full of parts.Dave Koehler wrote: ↑Tue Jan 14, 2020 11:08 amJust a quibble point on stress.

I was saying for the cylinder pressure required to hit X HP all methods get there in the end.

Re: 1400 hp Big Chevy combinations
maybe so, but we are talking about extreme budget parts trying to make 1400hp, its going to take or 8 shot of juice to get there. with cheap parts, may as well light off dynamite in those cylinders.Dave Koehler wrote: ↑Tue Jan 14, 2020 1:20 pmYou are saying that the nitrous is more spiky (a word?), detonation sensitive or creating higher pressure than needed.lefty o wrote: ↑Tue Jan 14, 2020 12:31 pmi disagree, tear down an engine thats lived on a turbo for a while and tear down one that made the same power on nitrous, and its clear the nitrous is way more abusive. the amount of juice required to meet his budget 1400hp will likely result in an oil pan full of parts.Dave Koehler wrote: ↑Tue Jan 14, 2020 11:08 am

Re: 1400 hp Big Chevy combinations
No worries. It's not going to happen. It's a quantum leap from a 900 HP magazine what if article to real world 1400 HP.lefty o wrote: ↑Tue Jan 14, 2020 2:04 pmmaybe so, but we are talking about extreme budget parts trying to make 1400hp, its going to take or 8 shot of juice to get there. with cheap parts, may as well light off dynamite in those cylinders.Dave Koehler wrote: ↑Tue Jan 14, 2020 1:20 pmYou are saying that the nitrous is more spiky (a word?), detonation sensitive or creating higher pressure than needed.lefty o wrote: ↑Tue Jan 14, 2020 12:31 pm

I did not address the quibble from a budget or HP goal standpoint. Just the wording in general.

Re: 1400 hp Big Chevy combinations
Just copy this guys build it’s pretty cheap if you piece it out used and it proved durable. Use the 427 and sell the S488 or trade for one you want in twins, any of twin VSR S480, Borg S475 or the China 78/7675 turbos will do, then all you need is a comparable head, cam, turbo headers/logs and piece together the rotator.
You could obviously tone this build down and cut some corners yet still reach your goal. You could use GT45 for super cheap or Borg S366 depending on who you buy from
