What happened to the HIH lines?

[frashdog]

I do not see them sold anymore.

I hope there was not any problems with them, leaking or something?

I supposed they just had poor flow rates and expensive for being over kill, if the HOH being sold now works just fine? Iirc it cost me $300 for the HIH lines.

Oh yea, Hi everyone! First post.

Welcome!
I don't know what happened to it but it seems that JAson wasnt so crazy about it after the fact.

Ah yes, the DFA HIH. I am at a bit of an impass on that one. The hih was tested extensively and under some pretty extreme conditions without so much as a hint at failure. We even contractred those out to be prefessionally made from aluminum and not pieced together. My biggest hesitation has come from the fact that they have to be assembled exactly right. If done right the HIH will far surpass any posssible requirements. If done carelessly it could result in coolant leaking into the fuel. Of the dozen or so HIH's that are out, none have reported an ounce of problem or so much as a drop of leakage. Again, my biggest dilemma is do we sell in them in preaasembled lengths? or trust assembly to the general public?

Pros- Extremely flexible, all but industructable, uses standard JIC fittings, can be easly assembled and diassembled and reused.

Cons- Expensive, could be disastrous if assembled wrong, relatively small fuel line size would not work for super high performance applications.

What do you guys think? IF there is interest, I will make it happen one way or another.

Well Jason I am extremely happy with mine. Did not get to test it in the worst weather last winter but will see how it goes this winter. Took my guys a little longer on the install just because they did not want to make any mistakes but she is running great and I love it.

Hey Jason,

Well I'll tell ya, I am a pretty competent diy guy. That said, I paid for the assembly and testing of the HIH, I would recommend the same to any one else as well. AND if I were selling them and knew the risks with improper assembly I would not sell the HIH without it being preassembled and tested.

I think those HIH lines are wicked slick. I feel like this is one of those "ala cart" items that should be offered to the wvo market, like the internally regulated FASS pumps, revolutionary. I am going to convert my jetta soon and I really wish the HIH was offered. I think anyone doing a jetta conversion, when aware of how little room there is to route fuel and coolant lines, would really be interested in the HIH. Maybe pimp the HIH on ebay. Many respectable companies use ebay due to the amount of people just looking, relatively cheap advertisement when considering the amount of people looking into and doing conversions. They just put their phone # in the add so you do not have to buy through ebay if you do not want to. I have seen HIH set ups for sale on ebay and they do not come close to the DFA HIH.

I live where it gets cold, regularly gets 0F out here and can stay in the single digits and negatives at night for days. The only issues with my cold weather operation was the filter of which I now have a heater wrap.

When I got my vegistroke kit....the first thing I did was open the box to see these HIH lines that I heard so much about, and saw advertised on the old site.

I was kinda dissapointed to see goodyear rubber coolant hoses and a couple rolls of insulation.

While I was waiting for the kit, I even bragged them up to my friend who installed my system for me......
He was like - "Where are those fancy hoses?"

I didnt have much I could say

HIH has Never been standard on the Vegistroke kit and probably never will be. While the HIH does what it is supposed to do well, it it still more complicated to install, allows more room for error, and most of all has no benefit(for most) in the Vegistroke kit. The HIH makes zero differance in turn on time and even on our systems that ran in -20 last winter still didn't have any issues. .

Extra parts, even if cool, are only good when they serve a purpose. If the extra parts don't serve a meaningful purpose, then it adds uneccessary complexity and cost.

[Clay]

That all being said, if they are not needed - even in neg. 20 temps - then why rish the problems that could come from using them? I say don't sell them unless you have a customer that is in a much colder climate and definately preassemple and test them.

The thought of coolant running through my injectors is kinda terrifying....

[frashdog]

So would you be able to tell if you were burning coolant, if you did not check your coolant level?

Would it be a lot of whitesmoke?
