also isnt 10psi, 10psi whether it comes from a SC or a turbo i understand the difference between the 2 but i had no idea that SC's were so hated.
PS take it easy on me please, remember i am a noob

10 psi is not 10psi
First and foremost you need to RESEARCH dude.
I tell guys all the time...you have to have a plan. Especially if you are on a budget. Otherwise youll make a mistake or have to redo something and spend more money.
When I was 19 I wanted to build a crazy 6-700whp freeway monster....as I got older and started racing I realized that while having a monster hp car is fun...you break a TON of stuff...you spend ALOT of money and in the end youll probably have as much fun as the guy who is bracket racing his car...maybe less because you break stuff so often.
So I understand you want to boost and drive the car on a built motor.
As you begin to read about engines, turbos, superchargers, cylinder heads, cams etc...youll start to see the rabbit hole is very very deep and you can get overwhelmed with options.
Being that I have been apart of the scene for jeez like 14 years I can tell you alot of fads have come and gone.
Jackson racing blowers in the late 90's were the rage. Back then if you were running 13's NA you were FAST...if you were in the 12's you were in the magazines.
The JR blower would take a GSR, add some boost and run high 13's all day....at that time to be smog legal, run 13's and do it on pump gas with hand tools was a BIG DEAL
But this isnt 1997 or 98....this is 2009 almost 2010....things have come A LONG way
Back then 10psi was like OMG high boost...now days guys will push 18-20psi on stock bottom ends with good tuning.
A stock B16 was pushed to more than 600whp on stock block!!! Crazy
So the tiny JR blower you have might push 10psi but its efficiency is limited in that range...you might see 5-8% more hp per psi with that thing. With an efficient turbo you could see 10-20% more hp per psi depending on sizing.
For example
12 psi on a PT67 ho turbo will yeild about 405-420whp on a gsr motor
12 psi on a JR blower will yeild 225-245whp MAYBE on the same gsr motor
We are talking STOCK bottom ends/heads etc
So why do people like JR blowers - easy to install - most come with plug and play piggy backs and they are dirt cheap.
Different blowers/turbos have different flow rates...cfm if you will...so they make different power because they flow different cfm at a given pound of boost pressure
Its an old book but a good one - Maximum Boost by Corkey Bell - read it...It will teach you the basics and get you familar with how boost works and tricks you can use to build your own setup.
Like anything else you have to crawl before you can walk and in this case you kinda want to run before you can crawl....
The good news is once you understand boost/turbos/compressor maps/BOVs/wastegates/manifolds etc...youll be mroe comfortable speaking with shops/racers/builders and can really let them know what you are trying to do.
Reading is free....mistakes cost money
A built D16 with a 57 trim will make crazy power for the street...400+ easily....at 10psi you can make 250-300 with a turbo or maybe 200 or so with the blower (which will be closed to maxed out)
