Intercooler kit for SC- gauging interest

I got the bracing trimmed with a die grinder/cut off wheel to facilitate the air diverter lip that will rivet to the underside of the hood.

I also got the hood mounted back on the Cruiser and the dimensions for the various heights (at each corner) of the air diverter. I'll be at the sheet metal shop in the morning to get them rolling. The hole appears to be perfectly lined up over the intercooler core. The diveter will seal again the edges of the core via EPDM D-seal (.75"x.75") when the hood is closed.

A couple pics of the trimmed bracing and the hole from the underside.

How many production runs do you think there will be? Have any of the land cruiser entrepreneurs shown interest in distributing the complete kit?
 
with the guys who are making the parts I can do one offs anytime. However to keep the price down @ $700 I have to get together orders of at least 5. Otherwise it will be more like $750-$800 per kit. If I could put together 10 orders at a time, it would be down to $650, but I don't think there are that many folks who'd be down for it. I've got three already in, a 4th signing up Friday and I think two more guys yet this week. I'm hopefully gonna cut this order off Friday, so the guys who are in can get their stuff before the end of April.
Cheers,
Nick
 
The intercooler and the flange. I'm picking up the air diverter this week, which I could make available as well, but different folks might have different ideas on this based on their scoop or if they have already installed a scoop and have a hole.
 
I got the diverter back from the sheet metal shop and installed it late this afternoon. It fit perfectly!

I attached the hood scoop as well. In the morning, I'm going to use some black caulk around the edge of the scoop (yes I said black caulk), and a little bead of silicone where the diverter is rivetted to the hood. Then I'll flip the whole thing over and attach my EPDM seal to the bottom of the diverter, and that should be it! Here are pics of the diverter installed. I'll get some final pics of the hood with the scoop in the morning.

If anyone is still interested in the first run, I'll need the deposit by Friday as I'm placing the order with the IC manufacturer then. The machinist has two flanges made, and will have 10 together by Friday! Any orders placed by Friday should be delivered within 2 weeks.

Next week my boost gauge and dual pod pillar mount (Acura) will be here, so I should be able to get numbers on boost. If anybody is interested in what I'm seeing on my Ultragauge, let me know what you'd like to know.

Basically using longer hose, I put it on the PS of the intercooler near the firewall.

However, the more I think about it, the more I hate the idea of the EGR system still on my cruiser. Especially after working to clean out all of the nasty crap that it deposits in my intake. Therefore, before I put my hood back on, I think I'm gonna delete the entire system and slap a couple block off plate in along with a resistor.

I did it on my minitruck and it ran cleaner (according to our old emissions tests) and it symplified a bunch of the crap under the hood.

Anyways, I'll try and snap a picture before I tear everything out.

Finally got everything mounted up and put back together. Here's a few pictures.

Here's a couple pictures (trying) to show how the air diverter seals up against the outside edge of the intercooler core.

Overall, I couldn't be happier with how the air diverter and seal worked out. It looks like I actually know what I'm doing!;)

Here's a couple shots of the Cruiser with the scoop and setup. The finish on the scoop I didn't buff all the way to high gloss as I'm a little concerned with glare (and I hate paint work). I'm happy with it. It'll take a little getting used to in the cockpit.

Seat of the pants analysis: This is like going from my old normally aspirated 80 to a SC'd 80 in terms of wow! It's not like I'm lighting up my 37s at 8,000', but I'm excited to hook up my camper and pull it over some of our passes.
:cheers:

PS, I still need to make a couple new holes in the hood for the windshield washer nozzles. I was too anxious to try things out to do it today...

Just found this thread today. Looks like I missed the initial run. Id be interested in the next one. My friend Inkpot probably got into the first run so Ill see how he likes the results.

again, like he said, its about cooler temps for longevity rather than performance out here in AZ.

nice work!

Just a side note to add,

Apparently Toyota was no stranger to OEM top mount intercoolers, hood scoops and functional louvers based upon this '91 JDM Celica. Looks kinda similar, huh?

I like this understated Celica scoop. looks like you can rivet in the entire square housing it comes as one piece?

Still interested in some kind of before and after intake temps if at all possible with a scanguage...
 
If anyone is still interested, I can piggyback on yesterday's order through Monday.

Inkpot didn't order, murph. I'm very curious to see what if any difference the intercooler makes in all around operating temp and under hood temps as well.
 
The only challenge I see is that it is sitting on top of the engine and while it is a much simpler design than water to air cooling, unless you install a scoop with completely sealed weather stripping, you wont realize much cooling, The OP seems to of been able achieve this with his design.

I agree with the smaller pulley due to youll be losing 1-1.5 lbs through the intercooler. With cooler temps you can probably pick up 3-4 pounds with no knock?

Some guys will run temp sensors both before and after the intercooler and measure the difference. this would be cool if you ever do this.

Please post up any measurements if you run any tests. Thanks for the great writeup and info :cheers:
