I just called the manufacturer 1800 032 037, and asked them for a 3" 90 degree bend - part no: 3316566S The chick on the phone didnt know if it was reinforced, and she also didnt know if it were rated to a certain preasure or heat rating. She put me through to an "expert", but he wasnt at his desk!

Sounds good, but a bit of a worry if it is not reinforced... I dunno, I guess it would be good to test it out somehow though. Maybe they do make some reinforced ones too. Well done warpspeed, good find!

damn, that is more than i was hoping to pay for! Thats why i was looking towards rubber instead of silicone. Where in melb do you think you can source some 3" radiator hoses from in melb warpspeed??? Zahos

Warpspeed: Well if u only need straight hoses, then purple pig on McIntyre rd sunshine will be your best bet! The have silicone aswell, but its like $180 per meter :lol: Just get some rubber hose, as its only a fraction of the price and it does the job. They also have clamps and other bits you might need. R31 Skyline Chick: Thanks for that. I'll give em a call and see how much they are, but i suspect that they will be ridiculously overpriced. Zahos

Would they be strong enough? The hoses I have now (straight though) are rated to 150psi. Also, The hoses will need to be 3 inch.

Does anyone know where I can get intercooler hoses (prefer rubber to silicone b/c of price factor) with 90 degree bends in them? I tried purple pig in sunshine as they specialise in these sorts of things but they only had straight hoses. The piping to my cooler runs to the factory plumbing, and the pipe that runs under the cooler hangs too low. If used a rubber hose instead of the pipes i had made up, I can avoid this problem... Thanks Zahos

OK I also have that stupid noise, it's 2 or 3 short squeeks, and it only even happens on cold mornings, or when the car hasn't been driven for a while. I haven't been able to trace the source of it as yet, and its really getting on my nerves!!!

Or it could be because the mechanic forgot to grease the thrust bearing properly. Does it make a very faint squeaking noise on idle? If so, the see what happens when the clutch is pressed. If it stops, then thats your problem. I currently have this problem, and its b/c the mechanic didnt do this when he replaced the clutch

so basically if the tubes are too big, then the surface area per unit volume of air ratio is decreased, hence the ability to cool as efficiently is also decreased. Is that what your trying to say Cam?

It's not just the size of the core that counts but the cross sectional area of the tubes, and the number of tubes your cooler has running accross as well. For example (extreme case), if you had an intercooler that was 3 meters high, 7 meters long and with 14 100mm pipes used as the tubes to do the cooling, I'd imagine that you would have an extreme case of lag and that your car would be undrivable because of the time it would take for your turbo to preasurise or fill that intercooler full of air before you reach the desired level of preassure in the plenum chamber! Not to mention that since your engine will be working on suction at this stage it would be sucking air from the cooler as the turbo is pumping air in! So with this cooler, you may never reach any decent boost. Now with a more realistic example, imagine a cooler 800 X 600 x 100, and with tubes that have a large cross sectional area. With a cooler this size, you would eventually reach desired boost, but because the cross sectional area of your intercooler is greater than the cross sectional area of your pipes running to and from the cooler, the turbo will have to spend a little time filling the cooler with air, until the preasure in the intercooler is equal to the preasure in the plumbing. Only after this happens you will reach full boost in the plenum. So you can have a "bigger" cooler, but if you do, then you should make sure that the tubes of that cooler are also in proportion for the kind of power you are aiming for, so that the cross sectional area of your cooler is equal to the cross sectional area of your pipework.

I've cut the front out, and I've made the barrier and put it in place. It is now almost as noisy as a pod filter! As for performance I did notice that the car feels less restrictive at high revs, my boost was upped by .2 bar, and boost hardly spikes now! I had to wind the boost back down, b/c at .9 bar it was running like sh1t b/w 5 - 6K rpm. Once I make the barrier more secure, and I put the foam on top to block warm engine air coming through, I'll be finished and I'll try to take a pic with someones digital camera 4 u to see! Where abouts in melbourne r u?

OK, I have just whipped up another one of my sh1tty pics that hopefully shows it in more detail

Actually there is no perspex divider at the back of the box, just the front! I used cardboard to get the shape right around the intercooler pipes, and the radiator support. Then I cut a larger piece on perspex than was needed, so I could use the heat gun to mould it into a shape that would fit nicely into place. It actually looks a bit retarded at the moment, but once I put the finishing touches it will look much neater.

Hey _turtle_, I went to make a start on the airbox like I said, when I realised that there was a MUCH easier way! I thought about what surreal said about taking the front off which gave me an Idea! I cut the front of my airbox off (like surreal did I assume), and I blocked off any engine heat from getting to the hole with perspex. Next I will put some foam/sponge on top of the airbox, and the perspex mould I made to completely block it off, and there you go. More cold air in 3 easy steps! I have attached an even crappier pic than last times...

I dont suppose you could point me to some of those tests cam? I bought one not long ago and I was curious, and I haven't been able to find any test on the web!

Another thing I was wondering, is if these piggy back computers are legal or not? I know a lot of aftermarket replacement ECU's aren't, but what about piggy backs?

Sounds like a good option then, and very extendable too! Only thing is, to find a mounting position due to the size of it....

I guess it does work out cheap then (given that the cost of tuning is too expensive). Does any1 know tuners that are familiar with the e-manage? I dont suppose you know then how it tuned in afc mode?

Even if you wanted to use it in the same fashion as an AFC, wouldn't you still need the software to tune it?

Well then, since we are on the topic, how about the R32 ECU's remapped for R33's, or the R33 daughter boards that are currently for sale. What do people think of those? I am a bit iffy on them, especially the R32 ECU's remapped for R33's!

What about the HKS S-AFR? How does it compare to the Apexi S-AFC? PS- Sorry for hi-jacking your thread adam 32

No need for PowerFC for me, I'm not aiming for 200+ at all. I dont often drive that hard so it makes no sense! I think 170 - 180rwkw is my target. OK, if the settings are permanent, then I'm happy with that. Only thing is I'd like to have it in an inconspicuous position where it's well hidden! I dont want theives breaking my windows, and cops breaking my balls!

I'm also debating which of these to go for, and I was wondering... Does diconnecting the battery reset the SAFC as well as the ECU?

For R32, it is a very easy mod! you just slap another pipe into the bottom of the box to get more cold air. The R33's flow air through the box in the oppisite way, and the lid does not have much room for a pipe to be put on, hence my plans to modify it! To clarify for those wondering the difference, here is another pic showing the differences.

Yeah.. 6'4", 105kg, and most importantly NO PATIENCE is how I managed that. Your solution sounds more sensible, but that would have meant that I should have gottern out of the car, grabbed something to lever it with, got back in the car, and tried again. At the time that would have meant more effort, and patience... (I would rather skin my knuckles than do all that.... less effort!) Anyhow brendanf, did u get it off??? I think maybe try JimX's solution first :confused:
