Got a p/n for summit? Only place I could find them was from TA or thunder racing.

 

MSR-7115 is the # for the studs... Funny story, on the inside of my Moser cover is a ta performance stamp lol. so must be built by TA for Moser.

 

Thanks. Lot of places rebrand other products I guess. Nothing wrong with TA's design anyways, right.

 

Here are some pics of the Truetrac. The pics came out darker than I thought they would, so I apologize.

Carrier bearings and shim kit:

 

Question for anyone that's done it: How difficult is it to get the stock ring gear off the stock carrier? Is it pressed on or can you just unbolt it?

 

Ordered a few more parts:

-Mag-Hytec diff cover
-AeroForce Interceptor gauge (green lighting to match stock gauges + SS bezel to give an OEM look to it)
-Wideband O2 sensor kit
-Gauge pod for in the mirror cover from 2007chevy5.3l

 

Just bought a whole lot of parts from Summit last night:
Ring gear bolts, main cap studs, pushrods, LS9 head gaskets, ARP head studs, exhaust and muffler, SS band clamps, split-lock header bolts, spark plugs, couple tools and few odds and ends.

I'm getting there, just a few more things and I'll be ready to jump into this.

 

It unbolts. Might need a little persuasion but it will come off.

 

Alright I'm stumped on an idea I have, so maybe we could get a discussion going about it.

I'm more than likely going to swap in an LS3 cartridge MAF in a 100mm housing. Also, I'm going to swap in a LSA/9 3 BAR MAP sensor. What I want to get out of this is:

• 3BAR output from the MAP for datalogging and to show on a scan gauge;
• IAT tested from the MAP sensor location.

Now here's where my confusion begins: Can the newer MAP sensors read IAT or am I completely confused here? I know the two tan wires from the MAF are the IAT low reference and IAT signal wires, so if it were possible to read IAT at the MAP I would need to run these wires over to the MAP. BUT the new MAP has 3 wires; ones obviously a signal wire to the ECM for manifold pressure, one's likely an input and the other ground? Have I just answered my own question, and the newer MAP sensors can't read IAT? I thought I read somewhere that on the LSA and LS9 that the IAT was placed (correctly) after the supercharger?


*EDIT: Alright after doing some research it seems like what I was describing is a TMAP sensor, which can test temperature and manifold pressure. And of the 3 MAP sensors on the ZR1, neither appear to be TMAP sensors from what I can gather from Bosch's website. So it appears the IAT is still being drawn from the MAF. So that's fine, that's how I'll set mine up too. Saves me the trouble of either tapping the lower manifold or welding in a bung for a separate IAT sensor. Won't be as accurate, and won't be able to warn me if the HX pump fails but I'll worry about that at another time and place.

Also, I ordered the 3 BAR MAP sensor from the ZR1 today, PN 12592525.

*EDIT #2: Turns out magnacharger does relocate the IAT sensor into the lower manifold, so I've been trying to come up with a trick solution for nothing...oh well, not the first time or the last I've wasted time trying to reinvent the wheel

 

Thanks Tim.
