AITs and AFRs and ****s

i don't think he's checked. he's never checked IATs/AFR. but never had a problem either. perhaps he's the luckiest man alive....

or simply leaking boost , or not generating full boost

i think he's very happy with his conversion! i could ask him!

[Lucky]

In the interest of testing I have just swapped pulleys over and now im running what works out to be 20% with a +3 crank pulley and a 17% charger pulley.

Stock, charger,head,cooler,manifold,injectors all stock.

Even at the first drive its very apparant! monitoring the IAT and A/F I took a drive around some local roads in the heat.

To cut a vary long story short, things do get hot (upto 70 degrees after 5 hard mins, but it did not get any hotter even when driven longer) at over 5500 rpm but they also get very lean depending where the boost comes in.

As Minimania says one quick blast from the lights upto 70mph does not have much affect but prolonged use above 5000rpm does warm things up.

later in the week Im hoping to add a larger intercooler and report back, then if those temps can be brought down I will start looking at the fueling at the high boost.
But what a hoot to drive around town!!

I know this is not a conclusive style test, but It would be good to see if the same things happen on different cars and also see some different cures.

I think Perms car is helped very much by his GRS.

Hi,
Guys I have asked Dave (*********) to give my car a health check next week. He will record temperatures and other "stuff" to see if the car is working within acceptable safe parameters.

I or Dave will report back with the findings next week.

Maybe the reason that I do not have any problems is that I do not drive for prolonged periods over 5,000 revs. IMHO, the BBR 220 conversion is a great fast road car conversion, it was never designed to be a track conversion where prolonged high rev (5,000 rpm +) driving is a normal.

If I am leaking boost or not generating full boost then I dread to think just how fast my car should be....

Cheers

i won't say which 2 didn't as that's as good as which 6 did! it doesn't matter, i call it healthy competition - not a big deal. they've all been nice straight forward blokes to talk to. it's just a case of sorting out fact from fiction from opinion.

on this thread i've spoken to....that will give you 7 tuners i think and one other not on this thread...............

Reason I asked what you would call a tuner is or example, some people have referred to Graham of GRS as a tuner because he modifies cars, where others woul not as he only changes one part of the engine (intercooler).

Just wondering thats all as didn't realise there where 7 mini tuners worth talking to lol

i wouldnt call myself a tuner im a parts supplier (i.e theres certain parts i wont supply as im not a tuner i dont sell heads if anyone wants the m7/cossie ones i send them to m7 to talk about them and then i import on their behalf,)

i refuse to sell crank pulleys, and i wont sell a cam till i run it and besides paul does the best cooper s cam, i would feel a cheap **** by trying to copy him and sell newman cams

i didn't count graham as a tuner, and haven't discussed mods with james at fomsport. they both come across as ace guys.
i guess i mean tuner in the sense of someone who puts together a series of mods to improve a car's handling and power.

I am always cautious , too many times with cars ,this years whizz bang item is next years bang !
things on cars dont get better with age ,limits drop , tolerances widen, materials fail , pushing the envelope may seem fun but in the end can be expensive
Very respectable companies like Toyota Race Development have played with the eaton and reached a limit where they concluded that at high ratios it was not worth it -the machine simply is not designed for it -far better to use another unit that is designed for it
I am fortunate in that the US side sells thousands of items and I get the feedback ,that helps when it comes to reliability - ie thousands pulleys sold
Way back in 2002 one of the first cooper s cars went to MM in the US and they played with that for years trying various things on track ,for instance with wta coolers 2 rads are needed for best results .
The Eaton is getting close to its ultimate limit now ,perhaps a few hp here or there ,then the move will be to other boost suppliers

Points well made!

Eaton TVS will be next for me I think.
