SK,

Your correct again i got the idea of some pic's you posted in the motor sport furum. The reason the rear ducts are so far forward is so i could mount the aluminimum strip to the bolts that are already in place from the roll cage. I was not sure about the fronts as i could not see any of that from your pics but i now have 2 ducts to each front wheel, so i hope that helps.

The reason i had to go 180 degrees on the rear is that unlike the Gibson GTRs which have the caliper on the rear of the rotor the standard set up sees the caliper mounted on the front. I wanted the air to be directed into the space on the back of rotor where the vains should be able to pull cool air through the rotor and this is the location i could do it.

On the front i already have a pair of ducting front the front of the car yet last time out i have a slight drop on the brake peddle at about 10 minutes of running. So i thought i would run another set to the rear of the front rotors to see if that helps next week.

Unless you have a trip planned to Dubai so you can purchase the alum duct in Sharjah i think it might be a little more costly back home. But yes i was home a few weeks ago and i did see it in Bunnings, what the duct is 90mm gas stove flue. And you will be surprised how strong and flexible it is. And the alum strip is just 25mm by 2mm and some alum rivits.

regards

good work mate. It will be interesting to see if it works ok as both the inlet and out let are facing the same way.

I need to get cracking on some fronts for mine too.

  • 2 weeks later...

Yep they worked a treat!

6 x 20 minute sessions in 40 + temp, no brake fade what so ever on standard calipers and Porject MU level 900 pads.

Little pic on me trying to catch Z06 corvette

Edited by tacker

Yer BB we are some what spoiled i guess as this is an F1 rated track. Although it does get a bit slippery with the fine sand being blown across it. And it was that way yesterday i caould see the sand moving across the track at certain points.

And another good thing is no gravel traps, the run off areas are all sealed and are huge one run off area at the end of the main straight is 120 metres before the inflated barriers.

You can do a search on it just type in autodrome and it should pop up.

And yes the brake ducts work a treat not one mm of pedal drop in 20 minutes of hard running in 40+ temps, quite simply the work very well if you are having problems with over heating brakes this worked a treat. I am really surprised just how much difference there was with 2 more ducts to the front and 2 rear ducts. I dont know which made the diff but as a unit they worked well enough to out last the porsche turbos brakes and they were lapping about the same times as me.

    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
    • I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
