    How will compression affect the tune

    Thanks for the replies guys :) My engine has been run-in now (I am not a big believer in a long run-in period) and this is what I have noticed. For the record I use an Autronic ECU with live tuning and logging facilities. I have an AFR gauge wired into the Autronic which is logged and I also...

    How will compression affect the tune

    Hi All I have been running with the same engine setup and tune for years, and it has been working well. The engine has now been rebuilt with some new internals including JE 9.5:1 compression pistons. The intention is to up the boost a bit as well (was at 1.4 bar wanting to go 1.6) My question is...

    Brake Cooling - An uphill battle

    Brake cooling continues to be a problem for myself and a number of my customers (who mostly run BBKs) As you start to get quicker around the circuits so the weak points start to show. For example a customer was running a 1'13" lap around the circuit mentioned earlier in this thread. At this pace...

    What does your IGOTASTi screen name mean?

    I am a member of our local club SOCSA (Subaru Owners Club South Africa) which runs an active forum much like this one. Because I grew right through my hairstyle it is important for me to always wear a hat at club, or any other outdoor, events to protect the naked scalp. The hat that best served...

    IGOTASTi gift pack

    Thanks Gents - I received my IGOTASTi T-Shirt and lucky draw hoodie today. Lovely stuff :tup: Nice design and superior quality. The challenge is going to be keeping them out of my teenage kids' clothing cupboards and in my own :D We are currently in mid-summer here and the last few weeks have...

    Suspension Tuning Guide

    I know this is stating the obvious but - Tuning suspension for a street car and an Auto-X or track car are two completely different things. What works on track is actually very dangerous on the street because it does not cater for surface changes and bumps etc. To dial out understeer on a car...

    Brake Cooling - An uphill battle

    It's a very short lap, here is an onboard video of a lap. BTW I have shaved about a second off that time since 2010. Another problem is that ambient temps at this track often get above 30deg C. @Zach - It wont be too difficult to set up at all, maybe a system triggered by the brake light...

    Brake Cooling - An uphill battle

    Post edited - pics sorted. We have a race team here that runs two 2008 model cars in a series called "Production Cars". They have had to go to extremes to cool brakes at the short Zwartkops track...they actually inject a water mist into the centre of the discs. This is in addition to a huge...

    Brake Cooling - An uphill battle

    The obvious solution would be a BBK but it comes at a price... As you have noted. I would also need to get two sets of 18 inch wheels and the cost of 18" tires is considerably more here. We know that the cars braking won't be better with a BBK it will just brake as well for longer. I am also...

    Brake Cooling - An uphill battle

    Apologies for the poor quality pics but you will get the general idea. The ducting runs from the Roo duct to a modified dust cover plate .

    Brake Cooling - An uphill battle

    The results indicated that the air "hitting" the car was being pushed past the front of the intakes and not actually going into them. Fitting the outside deflector was not really ideal, so I looked at different options. The NACA duct seemed to be the obvious choice because this was an intake...

    Brake Cooling - An uphill battle

    Over the last 5 years my car has slowly become more and more of an event car and less like a road car. The metamorphosis has included weight saving, significant suspension upgrades and some power gains. All in all the car has been very successful...I have had very few reliability issues and a...

    New to forum - introducing myself

    I am busy reading through your tuning journey thread and learning a lot, in time I may have to offer some basic tuning to customers and for this opensource will be the way to go. I have an Autronic ECU in my car and obviously the same tuning rules apply but with a far simpler interface.

    New to forum - introducing myself

    As fate would have it I have now become one of the "handful" you speak of. At the beginning of this year I closed down my furniture factory and was forced to find an alternative source of income. I had done all my own spanner work for many years and having achieved some success with the car in...

    New to forum - introducing myself

    It sounds like Hylton has had a bad run of bad debt - people not paying him in time. Also his health has been affected by the fumes in that under-ventilated dyno room. WRT Tim - Im not sure, I chatted to him today about it and he simply said that he has had enough of this industry. "driving me...
