hey, can i have a high comp. pistons rods valvetrain etc and SC it and squeeze 50 shots? or will it blow? cuz i konw turboing it you have to go low but you almost HAVE to do internals if you turbo it wanting to boost around 10psi...or is it just better to turbo my lude, do internals and boost around 16 fully built and squeeze? or just SC it, squeeze and internals? what way should i go? i want to run 12's pretty much but i will build my car definately but not sure which way to go too confused i want turbo but i want my nice VTEC to yell while its SC. any advice or recommendations would be greatly appreciated. thanks.

try 10.5-11:1 on stock block 8-10 psi ill let you know how it goes on thursday.

 

i dotn get what you mean, can u rephrase it.

 

FI + no internals =
FI + high comp =
FI + high comp + nitrous =

I'm sorry but man you need to do some more research. I suggest Maximum Boost by Corkey Bell http://www.amazon.com/exec/obi...07846

 

Turbo will get you to 12's for less money. I suggest contemplating and researching any form of forced induction and Search, search it good, use the search button like you should.

normally yes...but you know there is always the exception when good tuning is involved. ive got ed at balanced tuning mine on thurs. im running between 10.5-11:1 compression AND fully stock block w/80k+ miles on it.going to push 8-10 psi. however my gf has talked me out of hooking up the n20....for now anyway.

best of luck, but 'normally' you're asking for trouble

 

hmmm...I been boosted on stock JDM h22 (10.6:1) running 9psi for over 2 years. It is tuned with hondata, and I am running 550cc injectors.

im asking about hte High comp. and FI cuz i herad with a SC u dont have to do nething internally its a safe way to go cuz u wont blow the motor thats why im asking if u can go high comp. with SC.

 

any thing you need for a turbo, you need for sc, as far as internal....its the amount of boost that decides if you need to build...and 8# turbo will yelid more power then 8# sc

This about this. What the hell are our stock internals designed for? Natural asperation. This is a vaccuum sucking air into the provided space, and then squeezing it. Think about a drink. What do you do with a straw? Suck it up, correct? You can handle that just fine. How what about putting a "straw" into your mouth hooked up to a pump. The pump forces more drink into your mouth than you can handle.

Same thing with a turbo *OR* supercharger. The both pull the same function, just have different machanical ways of doing so. either way, the engine is not sucking anymore, but it's now having air shoved in. 12psi off of a turbo is the same as 12psi off of a super charger.

It's almost like saying if you fill a tire with a air compressor to 120 PSI it will blow, but if you pumped it up to 120 PSI with a hand pump it wouldn't blow because it's a different style pump. PSI is PSI

ya long story, i didnt mean to go that high, but once it was on there i said **** it...its lasted a week on my old boost maps, but i havent got on it hard yet...i hope i dont blow it, but i guess that means ill just have to finsh my other block sooner...

but like you said, i wouldnt recommend anything over 10:1 for the normal person

 

both supercharge and turbo charge will force air in your motor. If your boostin 9lbs on either turbo or s/c it's still the same 9lbs. Granted the turbo iat will be lower becuase of the intercooler but it's still ruffly the same force of air on the internals.

 

the reason why i asked is cuz someone had told me that the SC works in a diff way than the Turbo does. i heard that if you go with the JRSC u dont have to do nething with ur internals nor will you blow it thats why its SO MUCH safer. thats what ihad herad a lot so i thought that was right.

 

well whoever told u that is full of ****, and if i were u i wouln't ask them anymore questions about cars. If u look on po there's a nice big list of people who blew there motors on that s/c

You heard wrong. The high intake temps associated with a JRSC on a lude makes it even more risky than a turbo

With that said, I've been running a JRSC at 9 psi on my stock H22a4 and the auto SS tranny for nearly 10,000 miles now. However, I have an upgraded fuel system, programmable engine management, good tuning, and I'm reckless. I don't recommend others do what I do.

 

Im about to try to hit 10lbs on a greddy kit tuned through hondata, and see how that turns out on stock internals. If theres anyting that goes first, it will be the ringlands.

 

what did u run the 1/4? and what engine management u using?

 

waht did u do diff. after u blew ur rings?

 

how much boost did you run to blow em

 

No, SC @ 9psi is not the same as a turbo @9psi. With the SC you have parasitic drag because it runs off the crank via belt, Turbo runs off exhaust gas. That is why a SC with the same PSI as a turbo will never run as fast as a turbo. If your analysis was true every SC honda would run as fast as a turbo honda, and they simply do not.

 

thats hwat i had heard that turbo runs from the exhaust gas but and SC doesn't thats why they are diff. but i didn't say nething cuz i thought i might have been wrong. guess not, i was right after all

 

from what i read and heard.....its possible to run a very small shot of nitrous with a SC but its never been done and some say its damn near impossible....no one knows because no one wants to attempt it

9 psi is 9 psi. it's the pressure of the air in the intake tubing to the IM. Reguardless of what the hell is putting it there, it's still 9 psi in the same given area, which equates to the same damn amount of air.

yup, that is true. with same psi, SC lude might be slower cuz SC takes some power from the engine to boost the engine. BUT both Supercharged and Turbocharged engine internals get same stress at same psi. so...
whether you got SC or turbo if they're boosting same psi, you should build the
engine same if they're needed to be...
