Quick calculations would suggest that the piping configuration has an extra 45° bend over your standard 'up and across the radiator fan' config. I am only counting the bends on the outlet piping here, and assuming most people use the factory route for the inlet (to the cooler) piping.

Cooler to TB piping only:

The config in that pic has 1 x 180°, 4 x 90° and 1 x 45° bends = Total of 585°

Routing between engine and radiator fan has 6 x 90° bends = Total of 540°

Routing back to the factory locations has 1 x 180°, 2 x 90° and 4 x 45° bends = Total of 540° (well mine does anyway)

So the piping in that pic does have more bends than most layouts but whether or not the lenght of piping used is more or less is difficult to guess. I suspect when you add it all up there isn't much difference (length wise) between the 3 setups.

I have no idea what the laws of physics say about pushing air around a 180° bend as opposed to a 90° one but surely the sum of all the bends must have some bearing on velocity of the air and lag/throttle response etc.

Every bend causes a slight pressure drop, additional length/volume detrimentally affects throttle response (NOT the same as lag), so yes that would be worse off. But by how much? Well not a lot, i think it looks quite neat and it gets extra point for being different.

Gives you more torque if you can queue up the air in a nice straight line.

Why?

IMO the only real benefit of not having a bend in before the TB is to prevent any unusual flow patterns from messing with the distribution of air to each cylinder, and I tend to think this would be a small, if not negligible effect in the majority of situations. If you wanted to be pedantic, the safest bet would be to stick with the factory piping, as that's the only configuration thats had any real R&D.

I also don't understand your comments about air "backing up" at the throttle plate.

Don’t worry dude just stating an opinion, I don’t really care to discuss this boring topic in great detail. The standard setup is better I believe and it has a nice straight run off the throttle. If you like the windy piping in the Kermit car then cool, the difference it makes is insignificant anyway.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
