Say what? Bart's back in the house! That's a very lovely looking car; what lights are those?

That's right!

They are some E marked 5 3/4 units I found online Dave, require some modifications to the cooling fins on the back to fit in the original housing, but a massive improvement for the earlier 2.5 units

Not that familiar with the GTO3, but does it have an oil cooler mounted under the rear clam near the rear wheel?

If so, one option may be to move the oil cooler to the front where it actually gets some airflow. Pipes can be run down the centre tunnel. Certainly improved cooling on my M400.

Turns out the GTO3 doesn’t have an oil cooler so I fitted a 13 row one at the front. Also got the pro alloy radiator and fitted the oil pressure + temp gauge as didn’t have one. Seems the overheating issue is sorted. Faultless at goodwood last Friday and it was a very warm day. Aircon was not happy but car heat was sorted.
Shame the clutch let out a puff of smoke and the pedal went long at one point but it was very hot that day!

@coolchris, my Dad saw your at the weekend on his way back from Petersfield! Nice to know you’re still out and about locally.

Glad your keeping well Lawrence and the car overheating issue is sorted.Goodwood is a lovely track fast and flowing must be fun out there in the Noble.I was there last Thursday doing a half day(not in the Noble) and had a turbo let go it can be fixed luckily it was near the end of my sessions.

I had designed and fabricated 3 different roof scoops. This being the 3rd which I felt gave the best results that I was looking for in turns of ramming air towards the intercooler aperture and also imho looks really cool. I’m in the process of final tests on the scoop with low and high speed runs and final positioning of the scoop. Unfortunately I was hoping to have finished them but as usual other projects have snuck in and taken up my time. I already know that data collected have increased airflow towards the intercooler by a considerable amount. I just want to confirm them over various live speed tests.

Dear All,
Sorry to pour rain but that scoop isn't going to do anything. Happy to explain off list. Look back in the archives for the MIRA windtunnel stuff a few of us did way back when. Looks good though.

This forum is a bit...crap. But, since I like photos.

Mods:
- Honda 4 cylinder (K24A2) swap, lost 45kg(100lbs) of curb weight; 610whp, 485tq on a mustang dyno (similar to dyno used in the UK)
- GTX35R w/ 1.06AR. Full boost at 5000rpms, makes power to 9000rpm redline.
- quaife sequential gearbox with geartronics flatshift
- difflow diffuser
- APR GTC500 rear wing
- bunch of other minor stuff like undertray hardware changes.

Stunning!

Hi Paul
Yes Ive seen the wind tunnel tests that were carried out on the noble m400 in the Mira wind tunnel. Unlesss I’m mistaken, there was no video that I can see, so I’m assuming no evidence of testing the flow over the windscreen /roof line. If there was testing in those positions, please direct me to the video etc so that I can compare your findings to mine. However although you have stated it doesn’t work, I would have to beg to differ with your thoughts as I have live tested the airflow with and without this roof scoop, and I can guarantee you, that there is a significant increase in airflow directed to the aperture of the opening of the intercooler cut out on the rear deck, from the roof line directed through my roof scoop. My results are not just assumptions or guess work, but factual data logged live road testing at various diff speeds. I’m not pumping out this info, to try and market this scoop, I just like to push the boundaries and make things work more efficiency.
Thanks
Tony

I suspect Tony is correct , you can see the air hugging the screen and roof as we dropped the smoke lance .
Unfortunately I have a video but Pistonheads will not let me load it .

[tonyvan]

Hi Tux,
Yes you are correct, I’ve studies quite a few wind tunnel videos, and actually I ran a wind tunnel for an Aerospace Company that I worked for several years ago. Testing live gives a better understanding of the flow and dynamics although it means a lot of stop /starting repositioning the the air speed indication. But testing it live gives the ability to see the exact flow and as you said raising and lowering the smoke lance can show a bit of a curve ball, therefore actual rd test give accurate reading on flow , speed, volume etc. . If it works on Porsche gtr1 pigandi Zondas, McLarens and countless other cars with roof scoop, then there must be and is something in it. I’m just sharing the information, from the results I’ve tested and collated!!!

Dear Tony,
Yes I have videos. Tux's rear end is not the same as yours so no analogy can be applied. Your scoop frontal area is approx 1/20th of the intercooler frontal area and it ends at the rear of the cabin, i.e. no direct link to the IC inlet, It also lies within the boundary layer that flows over the roof, so what little air its going to capture is then going to be mixed with the rest of the stagnant air sitting in top of your engine cover before it gets anywhere near your IC inlet. in any event the outcome is not what air flow you can measure its what is the resulting inlet manifold air temperature? Thats what kills standard mapped Nobles. Happy to send you stuff off list if it helps. These are photos of what i tried in 2005, this didnt work, even when extended to a couple of inches beyond the windscreen. I hope you'll agree it would be pushing more air into the IC than yours. You can see there was a "floor" to the scoop internally.





Finally if you want to hide your registration you need to pixelate the reflected image as well!

Hi Paul, firstly I’m not trying to hide my registration no, if you look at all the pics I’ve posted, my reg is visible on all my cars. It just happens that one pic I used for something different. I hear your thoughts and your concerns about airflow to the intercooler Appature.
I have found with the tests and airflow measurements taken from several diff points on the rear deck, and I have found a significant increase of airflow that most definitely entering the intercooler opening contradictory to your thoughts. Lets beg to differ.
Just one question, have you live tested your designs rather than just using wind tunnel data?
Just to add, I also run a charge cooler, which we have touched on and had numerous discussion on this forum about. I’ve exhausted the discussion regarding the charge cooler, and how apparently that too doesn’t work. All my mods are based on significant testing and data collecting, if 5 K type thermo couples give me the data to show improvements, then that’s good enough for me to keep the mods in place, if they didn’t work, then they would have be removed.
I have tried a roof scoop kinda similar in principle to urs, this was an ex F1 Arrows airbox intake.The tests didn’t give the results I was looking for so I abandoned that design

Very fair point on the fastback clam Paul , it does massively improve the airflow over the rear of the car .

Is that an imported Noble, or is it a US Rossion?
I absolutely love them without the wing!

Is an m12 gto-3r in the US.
