What happens when it rains...?

Dude, Glad Wrap, jeez....

Back to the topic, I suspect it would actually be LESS effective than a conventional set up at high speed. I don't know how to explain the technical terms (help me out here, physics students!) but equate it to how difficult it is to breath when you're walking into a very strong wind....

1.Less than 2 feet IC piping with less than 150 degrees in bends.

Every bend or change in direction of air flow is viewed as potential flow loss. It is estimated at every 90 degrees(or three 30 degree bends)results in 1% flow loss. Compare competitors vs ASTRAY.

Can't argue with less piping/bends = greater flow. But given the figures they quote, @ 14.7psi boost pressure there is a difference of 0.85psi loss between the 2 setups, which is pretty negligible. I'm sure the type of intercooler core used would be most important when considering pressure loss.

If anything, they should be promoting the less piping=less lag.

2.No battery relocation = No drilling big holes for intercooler piping

I use a turnflow intercooler which didn't require drilling any holes or battery relocation. Battery relocation isn't a bad thing anyway (in terms of weight distribution). Also, it's a bit of a stupid argument when instead they require you to cut a massive hole in the bonnet instead.

3.Able to keep front bumper support

Removing the front bumper support jeopardizes your engine bay in a front collision.

I didn't remove or cut my front bumper support when I had a front mount.

What about cutting holes in the bonnet, wouldn't that jeopardize the crumple characteristics in a front collision? Also, the bonnet could easily be pushed into and damage the intercooler in a front collision.

4.Is not a V-mount IC

V-mount intercoolers are prone to heat soak. This often happens when car is not moving and engine bay temps heat IC.

How is the astray any different in terms of heat soak? Not only would it still suffer from heatsoak when the car isn't moving, it is also mounted directly above the engine which would make it worse.

5.Intercooler as direct cooling, no interferences from cars body parts.

You could achieve the same thing by having a hole in your bumper, which many aftermarket bumpers are already designed with (as opposed to a hole in the bonnet) not to mention the added benefit of ducting.

Out of the 5 "benefits" they list, I can see one arguement (shorter piping), 2 are pretty much irrelevant, and the other 2 would be worse when compared to a regular FMIC. The only other thing I can see is that a dirty broad minded person in heels is going to lay herself out on my bonnet for a photo.

And like other people already mentioned, air flow through the intercooler is going to be very poor without any ducting.

Asstray just needs to add a scoop to it so the FMIC actually gets air forced through it. I've illustrated this below. Note the extra room to add a "l33t" sticker on the side of the scoop so people realise how cool you are.

      Stock Airbox and Snorkle for RWC - VIC west

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!

      OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.

      OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
