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.

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.

The engines are not broken in at the factory.

They have minimal run time from a couple of tests, then some time moving the cars around. The actual break in occurs over the first couple thousand miles of driving.

As proven by the gain in hp after a couple thousand miles. If they were already broken in, they would have max power at delivery. Not the case, when a car is new many things are quite tight... such as piston to bore clearance. After some miles the clearances will be better and also better ring sealing = more power.

The rear end is what we are told as the major component for break-in miles. Even when we install the 9.5" LPE rear end they have us put 500 miles on said components before beating on it

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.
As we have seen there is a benefit in going with just a tune but these cars, and save with CTS-V's really benefit from intake improvements so a CAI will be a nice gain and we have already seen some impressive results with fabricated units

We have already tested a few components to drastically lower IAT's while maintaining an OEM or Race look. Reducing IAT's will allow for greater power output as well as consistent results on the street or track.

Spraying before the intercooler would be a bad idea. Seems like it would eat the intercooler alive more so then just not getting the full benefits. I would bet theres some good benefits for spraying it after the intercooler. I havent pulled apart a zl1 yet ,so not sure how possible it is and if theres a good outlet to tap into, but meth has plenty of benefits especially for a heat soak happy engine (more consistent pulls, added fuel, lower temps...).
