lol. passed with flying colors. im taking physics right now. sooooo easy. science, math and tech-ed/ auto-tech are the only classes i do good in.

i think you can see this. its a GREAT guide, its what i used. theres a part 2, somewhere. cant find it....

 

[xDJ DUBx]

I was good with math until it got to algebra. I'm still good with everything below that, like doing equations in my head really quick and such things w/o paper but all else, I fail.

I didn't really enjoy any class, I passed em all but never liked any of them except for a few choice electives. I never got to do anything having to do with cars so that kind pissed me off. lol.

Dub those Kumho Ecsta MX tires you were interested in are great! Wet weather they aren't the best, but since you said you barely get rain, they would be ideal for your conditions. They are cheap, last quite a while, and aren't overly noisy. Great dry grip too, almost as good as the KDW 2s I hvae now. I believe they were discontinued a few years ago, but theres still stock everywhere for them.

that sucks! well in a way im luck and not. my school canceled auto tech like 5 years ago cause some kid got REALLY hurt. so now i goto another school and take it. which is awesome. cause i only have 3 periods in the morning. and hour of "transfer time" so i just do what ever. then 2 hours of work on cars!! best schedule eva!!!!

CEL P2006
"Intake Runner Stuck Closed - Control Bank 1"

Tell me something I don't know.

So wait im still stuck on the different turbos thing. Any chance the difference in power is because of where the boost is measured, which is to say if you measured the psi right in the cylinder it would be higher with the bigger turbo?

Edit: Sucks about the CEL, have you gotten that CEL before or something?

 

[xDJ DUBx]

Nope, new CEL. I swear, I'm gonna hit all of them before its all said and done.

Told you to check the blinker fluid.

"Intake Runner Stuck Closed - Control Bank 1"

Tell me something I don't know.

iirc its either the vtcs stuck closed or the vice stuck closed..easy fix

 

[Protege03ak46]

shouldnt be unless theres some kind of boost leak.

 

[xDJ DUBx]

I was thinking it was the vics bulls*** too. How do I fix?

remove. lol

 

[Falango]

And here Dub was so excited and thought his turbo install would be so easy!!! Oh wait, he hasn't even started the fun parts yet!!

 

[xDJ DUBx]

Seems like its just a bad solenoid, still got the ones from the p5. No biggie.

 

[Falango]

Good thing you have a parts car!

 

[big Lou]

****** cel hope you figure it out.

HuH???

no, the difference is in a common confusion between pressure and volume

you can push 10psi of air into the cylinder with X volume of air flowing through the cylinder and get a different amount of power than 10 psi of air at Y volume of air...since a smaller turbo has smaller inlets/outlets and a smaller compressor wheel it cannot flow as much air as a larger turbo, hence where the power gain is to be had...the turbocharger has to be able to suck in a certain amount of air and force it through the snail fast enough to pressurize the system...larger turbos are more efficient at that because they have a large amount of real estate to grab and pull air in with, smaller turbos dont but can do it much faster

20 psi on a iiiiiiity bitty turbo may not necessarily perform more horsepower than 10 psi on a larger turbo, for example.....but a smaller turbo can spool up to max power output faster than a larger turbo, so you may have less power but you'll have a more consistent power band

it's all about researching which turbo size is right comparing the variables of volume, pressure, and efficiency, based off of various turbocharger's compressor charts

Keep up the good work. I knew someone that can use words (Count me out) would come along and properly explain this.
