When I hit the lotto, Will ya build me one?Sure! I figure I have about 2.5 million in labor in this thing! Ugh! Man, my old keister is tahrd!
Even though the LS series of GM engines are very efficient when it comes to the cooling system, I decided to put some vents on My hood, and also...it looks pretty cool. >>>SNIP<<<
Hood scoops/vents, with a little body panel adhesive, and some stainless screws from home depot.
Nice project! Wish I had the motovation(along w/ the space & $$$) to tackle a project like that, but just to carry the 'vette theme further... would an L88 style hood scoop have done the job as efficiently along w/ a little better aesthetics?Yes, it would, and they are expensive! I had to cut corners with a few things, to get it done. These oil cooler scoops were el cheapos from a speed shop.
I LOVE THIS THING! I'm assuming the rest of the drivetrain is up to the task. Please post a short video with excessive application of loud pedal. Please?Yeah, the ChryCorp 8 1/4 diff is pretty stout. 29 spline axles. The front diff is a Dana 30, and they need to be babied, so we'll see about it. The NV231J is a seriously stout transfer case. Mine has been modified somewhat with a 32 spline HD output shaft, so I doubt I'll have any trouble with it. I tend to not use 4WD off road, unless it's pretty slick. Most of the time, Utah slickrock has such high traction, You don't really need to use 4WD.
Oh, by the way, I'm up in the chilly end of IN. riding the twin of your bike, '08, AreaP, even a silver helmet hangin' on it. And believe it or not, I once had a fantasy of saving my big block and 3/4 ton drivetrain out of my old Suburban and stuffing it under an old Wagoneer. But I knew it was just a dream. $$$
It looks like you have your reversed hood scoops mounted on your hood far enough forward, but the base of the windshield is a high-pressure area. That is why the intake for your heater/vents are located there.That's some great advice! Thanks, I'm going to try blocking the vents, and driving, although, the high speed temp issue existed before the vents were installed. Still, I want to make sure they work, so maybe I'll tape streamers in them, and see which way they blow. Thanks, Man.
The windshield of your Cherokee has a steep enough windshield that the high-pressure area may reach far enough forward of the windshield base that your vents have actually turned into intakes, so the air from under the hood really has nowhere to go!
Your symptom of the temp going up at highway speeds indicates that this may be the case. Can you block the scoops, and see if the symptoms change? It should be easy enough to try.
I used to race with some guys that tried the same thing as you, and they ended up removing the exhaust "vents", due to the vents actually pressurizing the engine compartment. Once the vents were gone, the high speed temps dropped.
Nice work, Dude.Thanks JM.
