You should be able to squeeze about 15hp more out of it at STOCK boost level. almost completely stock and only a SAFC II(so no timing correction available) I pushed 263 and 233 lbs of torque at the wheels. My intercooler was slightly bigger(than stock), and I had about 1.5' more intercooler piping and a 3" exhaust. I did that on a DynoJet. Stock intake manifold and all. Not bad though. Ive seen a lot worse. I drove in with with 194hp on the first run in 3rd.

Looks good Jake. Sorry it's off topic but do u mind posting some pics of how u mounted and connected the mckiney intercooler. You could also pm me if you dont wanna clutter your thread. Ps can't wait to see the video.

 

There is a more cost effection option than the mkinney intercooler and its 4 inches thick and 33 inches in overall width. The intercooler core itself is 2 feet wide

The trouble is it isnt mounted =p

 

And as for the cost effective option, I don't have tube bending or aluminum welding capabilities and after considering having the Z trailered to some shop, materials, and labor I said forget it and just got the McKinney one.

Also I still have a miss, tuner said he thinks the issue is the coil pack harness. So I have to play with that when I have time. Also need to fix my fuel system as the pump seems to pump air when it feels like it.

 

Edit:

 

Upon closer inspection, I am not running the correct spark plug nor the correct heat range. Gap seems to be ok at .28IN however. Right now I have BKR6EIX plugs on the car and they should be BCPR7EIX.

 

He said to check it and gave me the NGK part number I should be running but I never got around to it until now as Ive been busy. Ill have to pick up a set when I have the money x]

I run basic copper core NGK, 2 steps colder than stock(for 1 bar of boost), and .033" gap. Any smaller of a gap and I get a misfire, and any bigger than .037" and I get a misfire.

 

I have been running the NGK and Autolite as long as they are the basic copper cores.

I believe Champion is NGK re-badged so they can also be used as well if the local parts guy doesnt stock the basic NGK copper cores(as most do not these days). I have a shelf full of spark plugs just for the RB that I bought during my dyno runs.

 

I believe I ran Autolite 3922 at .035" on the dyno with good results.
