Need a little help. Just installed a jrsc and when ever i start the car it seems to serge over and over again at idle. Running a 8lb pulley, jr fmu, aem fpr, stock injectors. Has anyone ran in to this problem before? If so what should i do? It looks like the engine wants to jump out of the car. Any input would really help me. Thanks

 

My first guess is definitely a vacuum leak... any weird noises along with the "surging"?

 

No strage noises that i can hear. I have an exhaust leak so i cant really hear anything else to well. Im pretty sure that i hooked all the hoses up right. The car is also idleing at 1500 rpms. I tried to ajust the idle on the throttle body but it stays at 1500.

 

Do you have a boost gauge in yet?

 

No not yet putting it in this weekend so i dont know what boost i am at. Thats probably not helping is it. I also have a jr timing controler in.

 

I made the stupid mistake of not putting my pcv valve back in one time..... Surged bad and smoke a little.

 

The boost gauge is a way to confirm that you do or don't have a leak... the motor should idle around -20 psi (at normal idle) - if it's signifigantly higher, you would have a leak.

I had the same problem when I installed mine - it was a crappy seal between the blower and the manifold, but it made a horrible whistle.

 

I will be working on it tomorrow. And also getting the exhaust fixed and proabably the guage. I will let you know where i am. Thanks for all the help

 

weird...i have a whistle under load in a high gear and at low rpms....but it sounds like the same whistle that was there before the charger from the iceman intake.

also, my boost guage will read between -20 and -25 depending...sometimes its -20, other times -25....

 

That whistle is from the throttle body - my car does the same thing at part throttle... actually sounds like a turbo spooling...

The horrible noise I was talking about was a huge leak between the blower and the manifold 0 it was so loud that you couldn't hear the engine running with the hood off - obviously fixed that.

 

-Any one ,
Mine is making a wierd noise, but only after 5000 RPMs...
It sound like it is the belt, but I'm not sure.

 

Are the bearings in the tensioner pullies OK?

 

well thanks for the help figured out the surging problem. Forgot to put the pcv hose on. all fixed now.
