LT1 Colder Air Charge idea...sort of

[SlipStreamZ28]

So for all the things I have done to my car, I've never done the Throttlebody coolant bypass mod. So since I don't drive my car in winter anymore I thought I would do it this weekend if I have some spare time. But I got to thinking, If GM was so nice as to put a seperate pass-thru into my throttlebody design for coolant, why not re-purpose it to flow through something to bring my air temps down, even if it just countered some of the heat soak in the TB. The question is then, what to use.

I know they make methanol injection kits and freezebulbs for the aircharge and stuff like that, but that might be a bit elaborate/expensive if not at least in the same vein as what I'm thinking. I also thought about rerouting the A/C refrigerant lines but the HP lost from the compressor would completely counter anything I was gaining and then some.

Any thoughts?

Not worth the hassle IMO. Plus, get the TB too cold and you'll ice it up.

You want to get the air cold but using the TB is a very inefficient way of doing so.

True, and the more I thought about I realized then the air passing through would have as close to zero time as makes no sense for cooling. But maybe it might reduce some of the Heatsoak from the aluminium in the TB, but again I suppose if your not getting it down to subfreezing it probably makes little to no difference.

It's just that the surface area is so small. I personally think the coolant bypass makes very little difference, maybe 10hp tops. But - it is free and worth doing if you don't drive it in the winter

Are there any good write ups for the coolant bypass??

Mine is bypassed and ive driven it in freezing temps without issue.

i did the coolant bypass on myine when i had the tb ported and polished. Before i did it though i took a drive on the highway for a few miles came to a stop and sure it was warmish. So i did the coolant bypass mod, got on the highway back home, the tb was actually coolor to the touch. Now i havn't noticed a difference, but seeing that the IAT is in front of the tb, i would imagine that the engine IS getting a more accurate air temp than what it was before.
