  1. I know a bit about his setup and am considering a seperate water cooling system for the turbo as well... just wondering what length others have had to go to.

     

    A TMIC means you get more air on the radiator which probably helps a lot.

    Hahaha ! You jealous prick because you have a high centre of gravity and can't corner fast without risking to rollover :P

     

    I am a bit jealous I must admit... if I had a BRZ I would have the perfect excuse for posting bad times at hillclimbs :P

    EJ engine vs FA engine?

    Maybe with the new engine design they have minimised or eliminated the issue?

     

    It will be a better sump/baffle design. Or the fact that the BRZ has no power and can't get up enough speed for high Gs :P

    ps  choice as a control tyre is no guaranteed indicator of good performance, way back in the early days of the nz production car championship they chose the awful goodyear gs-d3 as a control tyre. it was gone next season.

     

    Worst tyre I have ever had on a WRX by far... like driving around on rounds of wood.

     

    And R888s were good for the money... but now with the new model and greatly elevated prices you are much better off with Dunlops.

    That's a pretty sweeping blanket statement that might get someone in trouble. My nexen sur4g have incredible grip, street legal 200tw tire that the rx7 Pro series use as a control tire and rate as fast as an r888, toyo....


    Clubsub seem quite elitist on the Chinese tire hate :)

    That's an extreme example though right? 

     

    Generally speaking most of Nexen tyres on the road in NZ will be the very cheap and not great for the track variety.

    Yeah I know what use mean I am to nervous of the insainly large curbs at autox though if I spin it'll be a rim,arms and possibly suspension ha ha. 

     

    If I spin on the track hopefully I just end up in the grass. I'm not necessarily wanting to try slide it just as you mentioned know what's the limits for the car. But being new to track I doubt I will even reach those limits ha ha . 

     

    I am getting super excited 

     

    The autox I linked is on grass and it's totally safe to spin or the slide the car as much as you like.

    2cents, Subys that I've seen have engine issues on track are usually 'ambitiously' modified/maintained and driven very hard as one would drive an N/A honda (right up near the redline all the time). Generally the standard or mildly modified ones in good nick can cruise around all day no problem. 

     

    Driven hard sure, but any car can have oiling issues. It doesn't matter how well it was built or how well it is maintained. Even dry sumped motors can run into trouble.

    Hmm that's kind of surprising to me. I know there's some margin for overfilling by design but I would expect the margin to be closer to 1/4 litre than 1/2 litre.

    AFAIK the main risk is that the oil can get aerated and turn into foam which doesn't lubricate properly.

    Only time I've seen someone with overfilled oil at a track day had smoke come out of the engine bay and we discovered that there was oil all over the place in the engine bay. The oil probably came out of the breather. I reckon he had something like 1/2 litre above full but it was an 86 (Subaru FA20 engine), might be different with older models.

     

    EDIT : Oh and he had smoke come out of the exhaust as well, this what I noticed first

     

    And do you guys drain the extra oil after the track day or leave it like that ?

    Might be bad in the long term, just saying.

     

     

    Yes if you really over fill the sump the crank will be picking the oil up and chucking it everything. 1/2 litre appears to be fine though.

    If you want to understand why the oil spews out of the heads in a big corner watch this.

    Put a turbo and turbo extractors on it but don't plumb anything up turbo wise except the exhaust and oil/coolant lines. Run the N/A as per normal just reroute intake pipe. 

     

    Boom!

     

    Do it be Brave

     

    It'll over speed the turbo... you'd need to put a reducer on the turbo output to provide some resistance... or do you mean plumb the output of the turbo into the throttle without an intercooler? Would work with E85.

    Cheers for the reply! I haven't raced on this track before, is Higgins corner the one coming onto the straight?

     

    It's the RIGHT hander onto the back straight. You can be pulling lots of Gs for what feels like a long time and with a

    lot of throttle and high revs... try not to do that :) Killed my motor even with a good sump as lot's of oil poured

    out of the head breather into the catch can.
