Spooling help

[larrym]

Maybe an pre turbo exhaust leak with the added back pressure?

brad, that would make the boost higher

Damn I'm brain dead.

Wait til you're old

Made a thicker shim for boost controller, have It maxed out. Have actuator arm set at 1\8 inch pull to place over pin. 22lbs ran out of time but going to set arm  to 1\4 inch to pin and see if that gets me to 25?

[Steve Wood]

As said above,  exhaust leak,?  With it running,  do you feel a leak under the turbo where it bolts to the up pipe?

[Shimy87]

No apparent leaks. I can pour sea foam into the vacuum line that runs the brake booster to make smoke to find any leaks if I remember correctly?

[Steve Wood]

Worth a try

[Shimy87]

Been thinking and the symptoms car has are like the puck isnt sealing correctly. Will be checking that along with exhaust leak test.

[larrym]

Yes sir make sure it's lined up and the weld holding the puck is not preventing it from sealing. There is a thread with pics on the other board. 

[Shimy87]

Puck lined up perfectly, no exhaust leaks with seafoam test, no vacuum line leaks. This thing should be boosting like crazy??

Once upon a time...there was a guy up here in Canada. He bought a GN...and for the longest time he couldn't figure out why it took forever to spool. He one day took it upon himself to slide under the car to verify what convertor was installed. Instead of it being a D5...it had 7's stamped on it...which was a convertor out of a Monte Carlo SS with a 200...which stalled much lower.

At this point im satisfied with the rate of spool. What I need is to get it to push more than 22-23 lbs, thats all I can get?? I want 25-26 but with rjc boost controller shimed and completely turned in and hd actuator arm a tick over 1/8 inch pull to get on pin it wont pull more than 22-23 lbs even at the top of 3rd gear

[Steve Wood]

As I said, hd actuator should give 18-28 psi.  If you are using a stock downpipe with a stock exhaust housing, there is a chance that the factory puck is not quite large enuf to cover the waste gate hole, or the hole is slightly off center.  I believe RJC racing sells a larger puck that can be installed on the factory housing..

[Shimy87]

Stock housing, 3 inch downpipe, I checked that puck idea last night. put some red chalk line powder on puck and put housing back on and clicked it closed a few times. Perfectly centered over hole with about 1/8 inch ring of red dust all the way around so that seeems spot on.
 
Tonight I'm going to set actuator arm to 1/4 inch pull to get on pin and see if that helps?
