What are normal charge temps for a WAIC at 75 F ambient?

In all reality this is pretty awesome. I wouldn't sweat not driving it. Hopefully the way you are doing it, it will last for more miles and you will get to drive it more. Just look ahead to a point of driving it a bunch and then look back, it will all seem worth it.

Thanks Theman. Means a lot coming from you.
My wife's a bit upset cause she knows it's now going to interfere with the holidays. I'll try to keep that from happening (if I can).

Well, the larger hose and fittings helped cool things down - just not as much as I had hoped.
My charge air temps were hitting 220, now with the larger hoses they are maxing out at 150 F when EGT's are hitting 1300. Normal charge temps at about 7-8 lbs of boost (cruising @ 70 mph) put them at 122 F. EGT's are lower as well but I was hoping I wouldn't hit 1300 - I still can, it just takes a bit longer.

Everything is pointing to the IC (two Laminova cores) not being big enough.  However, the coolant flowing through the cores is not getting nearly as hot as it was. I believe it was nearing 180 before the hose switch, now it's not going over 120. One thing I love about the cores in the intake - instant boost!

Bottom line, I'm done with this project. The van originally had no EGT sensor or inter-cooler which is why I cooked it in the first place. Now I'm monitoring everything and will just need to back off and downshift when needed. I have also added a remote filter and oil cooler which seems to be working flawlessly. The turbo is rebuilt with the new 360 bearing and step-ring seal. The pump has the Giles touch, ARP head studs, new bearings, rings, one hole MHG, new GP's and pimped circuit. "D" style crank sprocket mod, fixed a bunch of wiring issues, added relays to the high and low beams, new radiator, stainless steel pipes under the van, silicone hoses, etc, etc, etc.

Now that it's in, I clearly have room for a bigger intake (using three or four Laminova cores instead of two). I could also go to a VNT-17 to move a lot more air than the K14 can. But as I said, I'm done. It's quite drivable as it is and time will tell how dependable it is. I feel good about it overall. It starts right up after a few seconds on the GP's, there's no oil mist at all from the tube I have from the hockey puck so I think the rings are seating nicely. I may even switch over to Rotella Synthetic pretty soon.

The plan is to daily drive it for a while and if all goes well, my wife and I will actually go camping in it 

Here's some shots of the "Y"'s I made for the larger IC hoses.







I've said it before, I'd never even attempted this without this forum and everyone's assistance.
Merry Christmas to all.

now that it is very drivable you can drive it. If you want to keep going, you have the opportunity to do so in the future. When you get 6 months of driving or more sometimes it seems like you didn't put that much into it and you can tear into it again. 1300f peak is no big deal really, I would have been very happy with that. Think about it also before with no monitoring what you got away with and all the work you did to it to get it here you will realize it is probably fine. Great to hear that it went well, happy driving, and Merry Christmas

And home for Christmas too!
you might re-snug  your hose clamps with the system warm to be safe.  The hose softens a good bit, and i had an embarrassing pop off on a customer  fuel line  i'd thought I got gutntight  in the icy cold.

1300 isn't terribly bad but approaching the red zone if it was a tdi it would be even less of a big deal. You still haven't dialed back the max fuel screw have you? Try an 1/8th of a turn out. All in all it looks great! Drive the hell out of it and have some fun! You will be better off than 3 vanagons I saw broken down in New mexico when I went to flagstaff back in october.

Thanks for the chin-up.
I'll be sure to check those hoses warm - good advice.

Iv'e learned so much here.  I received answers when I was stumped, bought some hard to find parts from members, joked back and forth - all good stuff, thanks all, just can't say enough.

Yup, just back off the max fuel slightly.  There's nothing magic about it.  Alternatively you could place a shim under the accelerator pedal.

I think Theman said his Giles pump didn't do much when he backed his off. I spoze there's no harm in trying though. I'm starting to get used to lifting my foot within a second or two after I hit the 1300 mark. I have it set for a red light at 1150

Just an update. . .
The Van is running well but the DIY IC just isn't cutting it (only about 40% efficient). There's lots of pedal left when I'm climbing a grade and high EGT's are making me lift my foot . My intake temps are hitting 122F and the water temps eventually climb as well.

I bought a Frozen Boost IC yesterday [/url]http://www.frozenboost.com/[/url] includingsome pipes, clamps and silicone connectors.

Recommended for up to 450 CFM / 350 HP


After taking some measurements, it looks like it should fit into the drivers side pillar and keep the piping down to the bare minimum.
I will need to tig up a new intake using the lower half of the one I am using for the modified IC, and will try to add some length to the runners as Theman suggested.

Really didn't want it to come to this but after all the work I've done, not being able to USE the available power makes the whole project somewhat of a failure. Hopefully, a real IC should put things right.

[libbydiesel]

At 122°F what was ambient?  70°? That doesn't sound bad.  Before cutting up what you have, up the boost.  Hotter EGTs result from a higher fuel to air ratio.  To lower the ratio, you can either reduce fuel (no fun) or increase boost.  Put the max boost up to 15-18 psi without increasing fuel and your EGTs will decrease drastically without sacrificing power. 

[Gizmoman]

Thanks libby but I'm already running 15 lbs on the K14 and really don't want to destroy it by going much higher. Also, it may be my DIY controller but it rarely hits 15 and when it does, it's not there for long because my EGT's are hitting 1300 and climbing. I think the two Laminova cores are simply too restrictive (probably needs three or four). I may tweak the spring in the controller and up it to 18 PSI but if the IC is restricting air flow, I doubt it will do much besides shorten the life if the turbo.

The new IC should allow for a significant increase in flow and if I ever feel adventurous I can go to a VNT 17
