- You're welcome for the write up! The PAW spacer set is basically a thick chunk of plastic that goes between the intake and head, and throttle body and intake. The spacer prevents metal to metal heat transfer. Dave told me at NASSAM that before the spacer set you wouldn't be able to touch the intake with your hand after running the car because the intake would be so hot. After spacer install he could keep a hand on the intake. Cold air is more dense meaning it carries more oxygen for detonation in the cylinder. I got the set for $100 on a "show special". If the 11whp claim is true, I'd gladly invest thousands of dollars at that return for investment. Dave's website describes them as:
This product was added to our catalog on Tuesday 26 April, 2011.
In our continuing improvement of the GM LNF/LDK/LHU engine platform is the WERKSracing LNF/LDK/LHU Intake Manifold Spacer!!! The High Temp HDPE material lessens heat transfer between the cylinder head and the aluminum intake manifold. Our testing has shown a 73 degree (F) reduction in thermal heat transfer between the intake manifold and the cylinder head and an 11whp gain with the spacers installed!!!

I mentioned on our club email awhile back that I had a failed attempt at changing my brake fluid by myself. I've been planning on bringing my wife into the garage and just doing it the old fashioned two person way "I open bleed valve and tell her to press and hold brake, squirting fluid out the valve, then close valve and have her release brake" rinse and repeat a million times starting with right rear, then left rear, then right front, then left front. Hanging out with the guys (and maybe Jo) and doing it in your garage sounds way more fun though. I'll make plans to go to garage day on the 24th.
I work pretty quickly when I'm by myself, with no one to talk to; but should there be any concern that we may not have enough time to do everything in one day? I'm almost afraid that maybe we should keep the intake valve cleaning for a single day by itself? I'm thinking that it would take me 4-6 hours of straight work to disassemble clean everything, then reassemble. I'll have a better idea of reassembly time after this weekend. I bolted the intake/throttle body up in about 3-5 minutes, I'm hoping everything else will take less than an hour, although several of the bolts we're wooly boogers to deal with.
Do you have the intake insulation/cover on the dragon? Do you have a venom bar installed?
