So 15lbs of boost isnt 15lbs of boost?
So 15lbs of boost isnt 15lbs of boost? So with my dinky 50 trims making 15 lbs of boost...thats not the same as say twin 67's making 15 lbs of boost?
can someone explain this to me or what...cause i see guys making 700+ rwhp on like 9 lbs of boost, then other situations where people are making 13+ lbs of boost with the same hp.

i always thought it was manifold pressure...so no matter how hard/easy the turbos had to work...the manifold saw 15 lbs of pressure...how it built it didnt matter.
i realize im wrong lol.
so what two turbos would reach close to 800 rwhp "easily" what efficiency turbos would do the job. i see guys hittin 700+ on pump gas.
also how much of this is attributed to the plumbing? will too small/large pipes and too many bends cause issues with efficency?

My twin T-67's will do close to 800 each. On just 8lbs it did 635rwhp; on 17lbs (blowing the tires off on the dyno) they did 875RWHP. 18-20lbs will give us the 1,000 we are looking for.
All of the SS's set up is one off. No kit.

Now for most kits just match the turbos properly to your desired boost pressure and you will see the numbers you are looking for. You need to post your engine combo to match the turbos. That changes things as well.

All depends on how much air you flow and how well the motor itself flows....
12psi with a big turbo will yield you more power than lets say 12psi with a small turbo would... Why? You're moving more air with the larger turbo
You'll see a drop in boost if you get a larger intake mani or exhaust manifold. Why? It helps the engine flow more.... Less pressure is being built up in the IM, and more of the air is going into your engine... That's what you want....
Plumbing/intercooler(s) have a play in it too.. Like Jose said... efficiency.

just think of it as colder air makes more power then hotter air because that air is denser, easiest way to think of effeicency.

A relatively stock headed 346 CI engine revving to 6500rpms at 15psi running a compressor effic. of 70% for both units would net around ~820hp at 190 inlet temps.
For the engine running 100deg inlet's it would net around ~955hp.

hahahaha honestly way to not answer my question at all. we know you need air and gas to create an explosion. thanks. roger. check. did you even read the posts prior to making yours? hahah
