Massive Spearco I/C's for American Turbo Diesel Trucks? Vmount Fitment?
 
Think I could fit one of these as a vmount setup? http://www.puredieselpower.com/catal...acturers_id=61
No good. What about SRT4 Stage 2 Spearco? http://www.intensepower.com/spfrmoinsr.html
The SRT4 one has a 23.5 x 11.5 x 3.5 Bar and Plate core plus endtanks.

What kind of clearance is there for Vmount I/C on a single turbo with relocated battery and small intake filter?

28" between frame rails, 32" between headlights, and 12" between front suppourt and water pump housing. Now, of coarse it is typically set at an angle to you have a bit more f-r room. Vertical hieght will vary on what radiator you use as well as how you make the backets to hold all of it. For $1500 just for the IC, I would just purchase a premade vmount kit. The neon one is much more affordable, but it will take some modification as well to get the inlet/outlet to work.

I just converted my greddy fmic to work as a vmount so if you can find a used one of those there is another option for you. - Jason at rx7store.net makes vmount kits for a pretty reasonable price using this ic as well.

If you just want to make your own kit, I know several people that have used some cheaper priced ic's from cx racing (most under $300) and see good intake temps. Just another option for you.

I went the custom v-mount route as well but I would probably go with a pre-built kit if I were thinking about spending that much on an intercooler before doing any work. Those are great quality intercoolers but you'll have a lot more work to do after that so if money is any object you'd probably be better off buying a pre-made kit like the HKS or Rotary Extreme unit. If you're willing to do the fab, buy a spearco core and make your own endtanks for your application. Cores are a heck of a lot cheaper than that (I bought a spearco core for my v-mount a few years ago for about $400)

Seems fairly compatible to me. inlet/outlet are in good spots for a Vmount. Inlet even enters endtank at an angle facing towards the turbo. Smaller inlets than ideal, however...

Just go through Spearco/Turbonetics directly and have them custom make an intercooler for you exactly how you want it.... exact measurements, endtank design, inlet/outlet tube locations, inlet/outlet tube diameters, etc. The inlet/outlet tube should be 2.75" outer diameter btw. I just had Spearco build me a custom intercooler exactly how I wanted it for my v-mount setup, and it was less than $600. Took less than a week to build as well. Here's a pic.

^ That's a great price and looks like a great quality piece. What are the dimensions of that core?

widebodyseven 10-08-09 05:36 PM

+1 on the size of that core

^^ Here are the final dimensions, ignore the comments on the bottom, originally, the height was going to be 9.8", but I bumped that up to 10.25"....

Maximum 10-08-09 05:54 PM

Nice. I think I went about 13" height with my core from them but other than that mine is pretty much identical.

That's a nice unit. I am not sure I like the sharp entry inlet angle to the endtank. The air flow is slowed as its rammed into the flat face of the endtank. I would do one of these with spearco with a revised inlet/outlet design.

Here is what I am going to price out. Any thoughts?

I understand what you mean about the inlet and the outlet location/angle, but I'm not running a single turbo. I have BNR Stage 3's, so I'm still using the Y-pipe which flows more naturally into the style of intercooler that I have. Plus, most of the companies that make v-mounts systems for our cars have similar inlet/outlet locations as my intercooler.... Knight Sports, Famspeed, Revolution, RE Amemiya, Odula, Rotary Extreme, etc. I'm not saying that they are all right and you're wrong because I understand what you are talking about. Also, without innovative thinking, we would never make any forward progress, so more power to you. I also considered other endtank designs as well to make the flow optimal, but in the end, I figured that air will immediately find the path of least resistance, so I went with a similar design to the Famspeed V-mount intercooler.

Here is spearco's drawing. I think the overall length of 30" might be overkill. I'd just be shooting myself in the foot when it comes to fitment. I might use the same core as pacman74 and use different endtank inlet/outlet.

The endtank you're proposing is more problematic than pacman's style. When air enters along the axis of the endtank, it can travel too fast to make the turn into the first few rows of core efficiently. Often times there can be a reverse-flow or siphon effect over the first rows of the core at high flow rates. In any event, the flow tends to be concentrated toward the opposite end of the core and full utilization [of the core] may not be realized.

Coming straight into an endtank, as is commonly done, is less of a problem than it may appear. (If the opposing wall of of the plenum is at least one diameter of the inlet pipe away.) The best location for even distribution is mid-tank. There is some evidence that a larger inlet tank or plenum is beneficial. What you're really looking for is the condition that will provide the most even distribution without excessive pressure drop.

Though the compressor side is in a good spot/angle the outlet will create its own set of problems with a vmount setup b/c of the extreme angles you will have with the piping trying to make it up to the TB.

The size of the other ic you are looking at really looks ok, it is probably close to the same size my greddy is.

The pics you posted further down are of better design but what was posted above by another user is a much more widely used inlet/outlet location and design for a vmount.
