A little birdie whispered "Air Raid" in my ear. Not my first choice (or even third, really), but I guess we all shake what our mamas give us.

In all seriousness, though; since when are you guys using AutoCAD and SEMA Transfer data? I thought you had to be a licensed manufacturer to use that stuff?

If you ARE a paying shop, I've got some cool stuff in development we might be able to work on together, if you're at all interested.

Since this car is going to have high underhood temps, maybe a ceramic coated intake tube going to a sealed off CAI box and front scoop might be the ticket to lower IATs. A standard black intake tube is going to be getting quite a bit of heat soak.
Russell,

The LSA engine uses two IAT sensors....one in the MAF and the other post compression side of the blower. There is nothing to "trick" anymore as IAT is critical to spark advance. What matters is what is entering the combustion chamber.

The lower temps are most certainly a benefit in producing more power output but the real gain on these engines is getting rid of the suction side restriction. This is the real improvement which will require a shift in the MAF table to correct. This means your into the factory calibration and compromise your factory warranty.

Hope this makes sense.

Great job guys, very thorough. Are you seeing similar KR levels like what I've seen with the SS's? Stock timing tables in the these seem to be a tad aggressive, even with 93 oct.

The stock afr seems right on so squeezing any power out of it must of been fun.

Is that some sort of baffle in the intake?

No baffle just the engine likes a larger diameter inlet and a straighter path.

Oh, i see what you were saying. I thought you meant the stock intake had a sound canceller or a baffle that held it back but I wasn't aware of one.

Much like the GT500 5.4L, hopefully with a larger, straighter intake the combo keeps making more and more power.

ZL1

Starting to think about performance upgrades for my ZL, going to be watching what everyone is doing very closely. Mine still has 60 miles on it so definetly waiting until its broken in first.

Sounds like some meth would do wonders for that stock cooling

Why doesn't anybody follow breakin procedures? Do any of the people who dyno their cares really have any knowledge of the reason for breakin? Please have people who can tell GM that it is not necessary too break in all the parts of the car. Who is the expert that can tell me if the various bearings in the car need any breakin! Having a grade 8 bearing worth 800 USD hours. It's a good thing transmissions don't contain any bearings or the blower either! Gears also don't need any breakin either. Why did Scott get on this thread and warn people about a breakin? Hasn't Scott always been truthful about every subject on this forum? Take heed unless you know more than GM,tell Scott and myself what you know about bearings and how hot they get on the first hours of running. The company I worked for used an infrared camera to monitor new bearings for heat buildup.
So it's your car do what you want.

Not unless you place the nozzles to spray after the air charge has passed through the intercooler, otherwise the incoming meth-cooled air would actually be heated up by passing through the factory setup. If there were any cooling benefits, they would be minimal, at best.

So it's your car do what you want.
You do know that all the LSA engines are broken in at the factory before they are ever placed in the chassis, right? Little chance of any engine bearing failure due to not following the recommended break-in procedure. And last I checked, Scott is not a mechanical engineer.

The 512 number was on a 70 degree night, Dyno not sure of but the type where the wheels are taken off and is direct connection. car allowed to cool off for a hour.
Sat we all went to a different place to see him Dyno again. Mustang dyno I think, 95 degrees and heat soaked with no cool off. Did 465 hp.

So it's your car do what you want.
I would love to see real data on wich componet supposedly needs 1500 miles.

It is not the engine because that is in the CTs-v and did not requre it. It is not the tranny because the tr-6060 is in other cars and does not need it. it is not the rear end as I have seen no gear manufacturer call this out. The mag ride in other cars does not call it out.

I think you see people avoiding it becasue nodody understands the logic to it.

Until I see some kind of engineering reason to break something in for 1500 miles I am not going to follow it.
