jrsc installed but somethins wrong

[ephatchback]

i just installed a 1st gen jrsc street kit on my ep..stock motor w sri and axle back exhaust w magnaflow muffler..my ac comp was shot so for th time being i bypassed the ac pully w a shorter belt..when we had everthing installed and ready to get the cai back in the car we noticed 2 thin hoses coming from the sc where it bolts to the TB that didnt seem to go anywhere..they look like vac hoses, but i couldnt find anythingn in the instructions that mentioned it..ive also searched the forums w no luck..we decided to plug the lines to avoid a vac leak since were pretty sure theyre vac lines..so the car runs..it honestly seems a bit slower than stock untill i hit wot..then i can tell the boost is there. im running the 5 psi pully..when im between half to 3/4 throttle the power bogs and almost stutters until i get it just before wot..im assuming those hoses were supposed to tap into the bypass or purge valve or at least the vac system, but im not sure. also my friend checked for oil in the charger and thought it was empty and added about 12oz of sc oil..the guy i got the chargr from said he put oil in it already..soooo....if anyone can shed some light on what might have gone wrong id def appreciate it..would putting too much oil in the sc cause problems? the 2 hoses im talking about are from th jrsc manifold and theres no place for them on the stock intake mani..sorry i dont have any pics at the moment but its 2 am here. has anyone had any similar throttle/power loss issues? i have searched all of this w no luck..i really appreciate your guys input..thanks- joep

Using power card?

It'll be easier to help out as well when we can get some pics. Can you upload some tonight?

[ephatchback]

nope...waiting for vafc to get here...i kno thats a nono, but from what ive gathered with my local tuner he said the car might run a little lean at 5psi if im driving it like an idiot but never said it would act like this..it feels like ive got a vaccume leak..just bogged down..also when im driving w the window down i can hear it hissing even when the blower isnt spinning...i kno i really need to get it tuned, i was just gunna drive it lightly till i got the vafc..right now i feel like i probably have less hp than i started with..thanks- joep

Oye.....a VAFC is going to cause more problems than good. There are a couple of members here and there with 310cc Type S injectors, using the powercard, and a 4.0" pulley. I suggest DO NOT get a VAFC. Did the "tuner" sell you it, or are you buying it from another source? I only ask because I think the guy just wants you to buy crap from him at his mark up, and then "tune" your car at his labor cost. A VAFC really honestly doesn't help.

[ephatchback]

ill find where he plugged those lines and take a pic today for sure..he ran the hoses into each other assuming they were both vac..when i saw them they were rite next to each other next to the tb and werent long enough to go anywhere...there arent any holes or nipples unaccounted for as far as i know..-joep

Definatly need some pics to help you out. If you want ill post a pic of mine to compare to. Only diffrece should be is mine has the map relocater

VAFC?

[MugenReplica]

P.S. I should also mention that I DO NOT endorse the use of a powercard, 310cc injectors, and a 4.0" pulley, BUT nobody I know who has done the "ghetto" race kit has actually blown their engine, so it may actually work....

DO NOT drive this car without a real tune or with a VAFC. You're just asking to blow your shit up, ESPECIALLY at Colorado altitude. Your guy doesn't know what he's talking about. Sell it and save up for Kpro if you can't afford it right now. Your trying to save a little money here is going to cost you a lot of money later.

PM me if you need to find a legitimate tuner. There are plenty around here.

i would def like to see some pics of the throttle body vac lines....thankyou- joep

Brake booster and PCV valve are on the big ports closest to the TB (behind EVAP solenoid).

The bypass valve is hooked up to a small port, as is the MAP sensor (or PowerCard).

For this discussions sake... remaining ports are capped.


Your MAP sensor needs to see boost. It cant because its reading air PRIOR to being compressed by the charger.

You keep insisting something is wrong and dunno why you have no power... its because an engine cant make power on air alone. Since you dont have a Power Card, or a MAP sensor relocator, or KPro... your ECU has NO clue WTF is going on between the throttle body and the head. It has NO idea there is an SC... so it doesnt add FUEL. Youre running LEAN LEAN LEAN.

At this point you need to remove the SC until you can afford either a power card or KPro. If you dont you WILL blow your engine. Even if you only make 1psi... its too much. PERIOD.

Im not trying to be a smartass but i AM trying to instill in you the gravity of what you are doing WRONG. Im trying to save you $$$. You complain about having to buy a PowerCard or KPro... how bout replacing your engine? You cannot baby this around town. You cannot take it easy and hope for the best.

[Euro-Yellow-Ep3]

WOW. The OE ECU cannot add more than 25% fuel long term w/o setting off another CEL. This means you CANNOT just hook your MAP sensor up to a nipple on the SC manifold... you will still run LEAN. LEAN LEAN LEAN. No VAFC. I hear the oh so familiar sound of the approaching ROFLcopter...

YOU NEED A POWER CARD OR KPRO. YOU NEED A POWER CARD OR KPRO. YOU NEED A POWER CARD OR KPRO.

There is no way you can just plug anything up and make it work right now. You have another car... leave your EP alone until you get engine management.

Amen. Couldent have said it any better myself

thanks everyone for all the help..all i have to go off is what ive been told..when i bough the sc i was told it would run fine w no powercard at 5 psi or lower..i was told by JR that it would blowup..im just trying to get as much info as i can from people that arent trying to sell me something, that have done the same things im trying to do.right now its parked...im going to get engine mngmnt asap and relocate the map and have it tuned..ill let you guys know how it goes..thankyou very much for all the help..im sure you guys probably saved my motor lol..thats why ive been on this forum for the last 10yrs..-joep
