Head Cam Intake ls1 2002 trans am

Also would you consider 234 overheating or just hot?

That's hot on the edge of overheating...

I like so see 190F-210F.

Im confused in regards to b4349 table in which I needed to make an alteration to the value to compensate for the bigger throttle body. From the TBresizing.xls file that is all over the internet, I am supposed to use a throttle area conversion of .0122 instead of .2xxx something from the stock ls6 manifold. Shouldnt my number be larger instead of smaller for this value and this might be the reason why my engine is running so lean?

My understanding is B4349 goes down as TB diameter goes up.

From an engineering standpoint, 234 is fine as long as you have the right mixture and a working pressure cap. That being said, a lot of people, including myself, run lower. I prefer 200-210 F only because if something does start to overheat I have time to react.

A quick search on ls1tech will reveal the entire spread of pinions on this. So I'll just say that the above is my opinion.

But I shouldn't worry about engine damage from the quick flirt to 234 ECT?

Just changed it so that both are on by 208 ECT

I've had mine up to 245 a couple times accidentally when the fan relay kept blowing and no issues.

I'm in the garage right now, but take a look at when your "hot engine protection" tables kick in. These tables kick in before damage occurs in an attempt to protect. Pretty sure you'll find 234 is within that limit.

I feel like I'm being a little lax. Let me be clear, I don't ever like being up in the 230s, ever. I get real nervous up there because I only ever get to 217 if something has failed .but I'm just saying it's not causing any physical damage at that temp.

I use these Fan temp settings:
G0901: 206
G0902: 199
G9013: 214
G0914: 207

Your brief excursion to 234F is ok.

[oreobadr]

ok good, there is some peace of mind right there! I think I find at least one source of the vacuum leak which is the throttle body attaching to the intake and some possible interference with the water pump. I will keep yall posted!
