one thing i noticed when dropping the engine this weekend was that
the heater blower on top of the engine is mounted in a slight angle
and when it rains hard, it fills up with water!
get's into the hoses too.

you turn on the heater fan and it'll blow loads of water into your heat-exchangers
and eventually into the longs!

gotta need to attach a small block off plate to the underside of the lid
right over the fan.

Thought you Cali boyz didn't have rain

cheers,

Thanks for the heads up. I have a GT style engine as well

I have a GT style lid, but,
1. Don't take the teener out in the rain.
2. Don't need no stinkin heat, or exchangers.

Worthless 70's gimick. If the temps dont drop when you completely remove the engine lid... then a GT grill doesnt do anything (except let in water when it does rain...LOL)

Andy and I tested the temp drop theory on the way to Arkansas last year. Had a 74 2.0 that appeared to be getting hot. Removed the engine lid... didnt change the temp one bit. Removing the rain tray is plenty.

So remove the rain train in the summer. and put it back on in the winter? Does that sound like a good idea? cus thats what Im doing....

andrew

You got it.

I want one so you can see the engine through the screen. I'll trade ya Andy.

I don't understand Brad... my carbs were sucking so hard on that damn thing it was concave! I had to double screen it!!

Given our great PCA rules about cutting sheet metal, I still think a GT hood, along with a big fan (1600 cfm) pushing air out through the oil cooler works.

Proof - before (old style hood) with fan (600 cfm) sucking air in didn't work at all. Just about everything in the engine compartment was cooked (wilted) after running at Buttonwillow (hot place).

After - with GT hood, allowing more air flow in and out, along with a big fan (1600 cfm) blowing air out through the oil cooler worked better (cooler), but still need another 105 degree day at Buttonwillow to confirm. I did have a big 4 inch HD drain pipe scooper at the bottom going through the (removed) heater ducts to get more up into the engine compartment.

Probably a front-end oil cooler, with free air is the only real long term effective way. Strong air flow is the only real answer.

I like the oil cooler mounted in the real spoiler, but then the spoiler is just for looks.

Randal,

Do you have pics of the scoop you are talking about? intersted in getting more air flow to the engine bay....

Because you changed several things and not JUST ONE, your results are inconclusive whether a GT engine lid contribute to engine cooling. It simply could've been the bigger fan -- that would be my logical guess.

Remember, when testing stuff, you can only do one thing at a time to determine what actually gives you the results.

I ran a couple of track days with the GT lid and a 11 blade fan with smaller pulley and saw very little improvement in oil temps. Putting the oil cooler in front is what made a big difference.

this is all good and everything, but i never intended to use the GT lid for better cooling anyways.
my engine doesn't run hot at all.

i wanted more fresh (read: colder) air for my little air intake.
with the stock lid and the rain-tray, you're sucking nicely pre-warmed air into your combustion chamber.
that's what i wanted to avoid and that's what i got the GT lid for ...
