AS YOU ALL KNOW I HAVE HAD THE S/C FOR A YEAR NOW AND ABSOLUTELY NO PROBLEMS EXCEPT FOR THE SURGING BETWEEN 2-3K RPM, DUE TO AIR BOUNCING IN AND OUT OF THE TB ON OR OFF OF THROTTLE. I AM FINALLY GOING TO GET A BYPASS DIVERTER VALVE INSTALLED ON THE S/C TO RELEASE THIS UNWANTED PRESSURE, DURING SUCH TIMES THAT IT EXISTS. MY BOY BUILDS TRUBOS AND WORKS WITH S/C'ERS AND IS GOING TO BE DOING IT FOR ME. HE SAID IT IS GOING TO MAKE A AIR ELEASING SOUND, WHEN EFFECTIVE AND WILL SORT OF SOUND LIKE A BOV.... LOOKING FORWARD TO GETTING RID OF THE SURGE. THE DIVERTER VALVE WILL BE GOING INTO THE S/C ELBOW CONNECTING TO A LINE RIGHT BEFORE THE TB... WITH SLIGHT INSICIONS BEING MADE ( BTW, HE IS AN EXCELLENT ALUMINUM WELDER....) LET ME KNOW WHAT YOU GUYS THINK???

 

This should sound nice.

 

 

please post sound clips and tons of pics. Sounds like a good idea.

 

sounds good to me, diff wanna see how this turns out,

i just love that sound

 

Are you sure you wired the ACM up right? I used to have the same problem before I wired the knock sensor around the ACM. I have no surge at all. As far as the blow off valve I will leave that to someone with more knowledge on that, but it doesn't sound right.


Ps. The caps may keep people from responding to your questions.

 

how much pressure are those blowers throwin anyway?

 

Lordy...
BOVs are for for turbo's, and they serve a purpose. The surge in the SC is not due to the reason you describe
On this SC, a BOV will NOT stop the surging, and it's only the same purpose as this wonder of science:

This topic has been well covered here as to why a BOV won't work, please take the time to research this before you pay "your boy" to make something that will do nothing but make noise.

 

^^^ Hahah.. can you believe that shit.. I actually saw that on a civic once!

 

nothin beats the turkey call in the exhaust hahaha

 

not a bov a bypass valve

 

What is the reason for the surge with the S\C? Kennedy is saying that it isn't the reason that ssmtl2nv says it is. Anyone else have any imput on this?

 

Not much difference. BOV vents to the engine bay, Bypass vents to the intake. Niether will solve the surging, as the surge is a tuning issue.

 

Tuning. Comptech uses a piggy ACM on the stock tune. Engine/Tuning parameters are sort of "over correcting" the adjusted ACM signal.
The surging isn't bad at all. Folks overplay it here, becasue they've never experienced a car that really surges. Most folks worrying the surge issue don't even have a SC.

 

^^ Got it. Thanks for the clarification.

 

dunno the surging is like off throttle... jo, when I drove it... don't even think it matters...

I'd focus on getting that comptech on lol

 

its not serious, but I want to experiment anyways

 

GL with this, BUT it is not going to solve the surging issue like kennedy said. the surging is do to the ecu getting stuck between open and closed loop, causing the injectors to pulsate. the ACM doesnt have the ablility to compensate for this and a piggyback with a good tune is the only solution.

oh and IMO atmospheric bov's are GAY... most of them will make your car backfire and run rich at WOT.. PLUS, that stupid pssssss sounds always kills it for me after hearing a nice turbo spooling. i dont see how you guys think that sounds good


recirculating bov's FTW.

 

thanks Sean, Im not a fan of the sound either.... just wanna see, makes sense... btw I wanna run a snow meth kit, any reccomendations???

 

sorry, using my phone....

 

he is doing it for free, experiment ftw... Money is not everything to certain people...

 

im going to go this route too eventually. the only recommendations i can give you is make sure you plumb it after the charger. ive seen a few members here mount it before and that can cause premature wear to the rotors. most of the boost coolers ive seen (3rd gen tl/7th gen accord), they mount it on the elbow before the manifold. my plans are to mount it right after it leaves the blower shown in this pic



^^ i think it will give much better distribution this way. im also contemplating using my windshield washer resovoir to hold the methonal too, just incase. methonal injection would be a huge fine, especially here in cali. =/

 

just bustin' your balls

 

makes ense im gonna keep that in mind, thanks.

 

kool, just making sure...

 

it would be better to install the nossle on the pipe with the sensor a few inches up after the sensor so you don't drill into the main S/C, but an accessory pipe thats quick and easy to replace later on.

 

true, thanks for input

 

lol
