Torqstorm lower boost after new clutch and transmission

[neitzelm88]

Hey all,

I have a 2010 camaro ss with an ls3 and manual tr6060 transmission. I have a big cam, headers and torqstorm supercharger. Earlier this summer I snapped the output shaft of the transmission. I ended up upgrading to a mcleod rxt clutch and stage 7 tr6060 transmission from RPM transmissions. Before all of this, I was getting about 8.5psi of boost. Now, Im only getting around 6psi.

Any ideas on why this might be happening? Engine seems to run fine. Seems a little more sluggish at low rpm. Im leaning towards a vacuum leak but wanted to see if anyone else had any other thoughts before diving into this further.

Are engine RPMs staying the same? Is the Check Engine Light on? Do you have a boost/vacuum gauge by chance? If it was a vacuum leak, your boost/vac gauge should indicate it.

Since the boost from a centri style blower is directly tied to engine RPM, your looking at three possibilities:
1. boost/vac leak (vac hose, boost line, bypass/blow-off valve, etc.)
2. belt slip
3. mechanical issue within the head unit

It also makes me wonder if your previous tranny/clutch setup was slipping a little bit, allowing for more RPM at a given load.

A big cam could definitely cause low speed sluggishness, but that would have been there from the beginning.

Provide some additional info if you can.
