Waste of time. Cool idea just turbo wont work how you plan

both of these guys said it would not work

but no i dont have the resources to do it and this thread was only started to see if any one knows the amount of boost the 6psi turbocharged air compressed another 6psi in the supercharger would be

Ohhhh oh ok, well never mind then haha.

Now I'm not sure, mayb e I'm a bit too ------- redneck, but I'm pretty sure I can read.

i want to do a twin charger setp on my car. i want to make alot of boost and dont want any lag. so i have the supercharger for instant boost then a huge turbo top end boost so i get a 6psi s/c then take that 6psi and compress it in a turbo to compress it another 6psi will i have 12psi final or 36psi final. what do you all think

I can't speak for the rest of you, but the part about you wanting to do this, stating why, then asking for advice, led me, and others, to believe that you actually wanted to do this. We all knew you couldn't for lack of ability, but for lack of everything else needed as well? You really are a retard. Grats!

However, if you really wanna know. In elementery school some of us, apparently not you, learned simple addition. It went sorta like this:

If you have 1 bean, and Sally has 1 bean, and you rape Sally and steal her bean, how many beans do you have? Then you wrote on a piece of paper, 1 + 1, and bow chica wow wow, you've got 2. So by replacing the 1's with 6's, in accordance with your boost levels, we get 6 + 6. With a lil bow chica wow wow, we get 12. HOLY ------- APE ----.

However, you're a ------- retard, and it doesn't work that way. The amount of boost you will get is solely dependent on the most important component of a turbocharger system besides the ------- turbocharger. I don't expect you to know what that is, considering your extremely limited IQ, and extremely abundant ignorance, so here goes. A wastegate. Goddamn I should be a rocket scientist.

z34 your obviously an idiot and there is a clear and apperent answer to the question maybe in elemntrey school all you learned was addition but i also learned multiplication here is the equation and answer
14.7+6=20.7
20.7x2=41.1
41.1-14.7=26.7
the answer is 26.7psi. i started this thread to see what kind of retards started visiting this forum and you are obviously one of them. and obviously this forum is not salvagable anymore due to the complete over run of retarded know it all like you so on a side note go ---- yourself.
and waste gate has nothing to do with the question when i said 6psi so congratulations you have officially avoided a question by spouting out more bull ---- you ------- idiot

If the SC is runs on pressure ratio like turbos do, you have that wrong. If your SC is set for 6psi (a 20.7:14.7 = 1.408PR) then feeding it air at 20.7psi would net you 29.15psia or 14.45psig.

I'm not sure a SC works this way. This is why the WG issue was brought up. Lets say you are holding a 1.4PR with your turbo and you have a 1" exhaust. Step up to a 3" exhaust and with a big ass wastegate you are still holding a 1.4PR but flowing a TON more.

Same scenario with the SC, 1.4PR going through a 1" exhaust. Step up to the 3" pipe and all of a sudden you're flowing a lot more, and consequently your boost has gone down.

I don't know if that makes sense, but I believe that the SC being crank driven and positive displacement, the pressure ratio you get out if it is dependant on pulley size and what's flowing into it, and what it is flowing into rather than something you can simply set like the turbo. That is, when you put a turbo on the supercharger, I don't know that you could (easily) calculate the end result at the manifold.

I've been wrong with these ideas before. I'm not wrong about the pressure ratio though.

Obviously I am. Engineering degree and national certification be damned. All of the research and design into my car be damned.

Look, all your numbers are completely useless, because the wastegate controls boost--Nothing else. So yes you will theoretically see 26.7psi of boost without a wastegate (Actually slightly less). But why the ---- would you run without a WG, or with it's feed being between the turbo outlet and blower inlet? So you get 26.7psi? That would surely blow most of the motors here. Not to mention how inefficient it'd be.

How does the wastegate have nothing to do with it? It controls the pressure in the system. Sure, plumb it and it won't, but why would you do that? You'd overboost in a heartbeat.

well you show little intellegence from most of your post or you just have a huge inability when it comes to reading comprehension i said the turbo is pushing 6psi(controlled by the wastegate obviously). so why again would it be inefficient.

AaronZ34 05-09-2009 11:07 AM

So what's making the other 20psi?

exactly point. its called physics man. if i was you i would try to get a refund on that engineering degree and "national ceritfication"(what ever the ---- that means) becyase it really seems like you wasted money on that to not be able to understand a simple concept of compression.
ill break it down more simple for the retarded
air goes in at atmospheric pressure (14.7psi)
turbo compresses it 6 more psi (20.7psi)
then s/c compresses it again at(20.7psi)
now what should the pressure be even thought both syatems are only at 6psi. tell me that sir
