so i am looking into the option of running a rear mount radiator so i can do a V-mount set up with the intercooler.

my car set up is BNR32 with RB30/26, big single turbo and looking to push 700hp with a future goal of 1000hp.

rear mount seems to be more effective then traditional mounting area because the path for air intake and exhaling air "CAN BE" very fast, smooth, and efficient if you spend the time to channel air in and out of the radiator.

mounting the rad in the front really limits how fast you can transfer air out of the engine bay, your engine is in the way and your hood is sealed, there's just no way to get hot air out.

now i am no engineering, i just dream about stuff like this at night.

so my question is.

with PROPER air channeling to the radiator, how effective will rear mount radiator be for street/daily driver/weekend track ????

thank you in advance.

Going off the setup on the car pictured, looks to be alot of work for a street car...

It will also require moving the fuel tank.

And if you plan to drag the intercooler back there as well, i suspect alot of lag will be induced.

If you are really thinking about doing this, i would actually consider moving the firewall and engine back, to get better weigh distribution, and do a proper v setup in the front.

Seems like similar amout of work, for better results.

The only rear mounted radiator I have seen was on a MB500V8 and it was boiling! Pipework everywhere and a major pain to install and maintain I would think. However anything is possible with enough time, money and will.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
