    Datman55, I'll have a mazworx kit in a few weeks (hopefully) if you want to check it out.

     That would be great, let me know when you get it.

    First track day completed, and the expected issues came to the forefront pretty early on......

     

    Water temps went through the roof after 1.5 laps at full noise, and the brakes were fading at the end of the first lap! Made it tough to get comfortable in the car and learn what it could do. 

     

    Water temp was the main issue last night, so a new radiator is on the cards - any recommendations????

    Also looking into getting some R33 GTR Brembos on the car with some good pads. That should sort out the brakes for now.

     

    I weighed the car also - 1,311kg's ........ Starting to strip the car this weekend, so will be interesting to see what we can do with less weight, brakes and a car that can do more than one hot lap at a time.

    Other than a bigger rad, get an oversize water pump pulley as the overheat is from cavitation - common problem in SRs

     

    Car look great out at no limits last night! Except maybe for the belts squeeking

    I have an oversized pulley, only good for high revs.

     

    Koyo rad, check out jap car facebook page. There are some for sale cheap or hit me up, I can help you out.

     

    As for brakes, two options which are great:

    • CTS-V brembos from the US (AC Delco/Brembo) - $180US/each plus shipping. 4 pots
    • Evo 6-9 Brembos also 4 pots. 

    Both need adapters but cheaper overall than running 33GTR brembos and larger than 33/34 brembos :)

    Talk about picky !

    bloody s15 owner :P

     

    ichi and I have Koyo rads, seem to work well. Mine used to overheat all the time before this.

    Have 33 gtst calipers up front with pmu pads and dba rotors.

    Works pretty well for budget upgrade. Fluid is also important. motul rbf 600 works well.

    I may even go electric water pump, we will see.

     

    The belts squeeling was weird, comes and goes. Never done it before (although I have hardly driven it until last night). Maybe it wasn't happy about the power run! Plenty to do.... let the fun begin.

    I wouldn't mind getting a price on the Koyo Radiators.

    Here you got Datman (RE brakes)

    http://www.silviawa....showtopic=73171

    20% increase in braking torque and a big increase in thermal mass.

    I'm even negotiable on price.

    Thanks man, probably the cheapest option I have seen. My concern though is the weight. I am trying to do everything as light as possible. Would you consider selling the dog bones separately? I am planning on going two piece rotors to save weight.

    Found the source of the Squeeking belt.... Lock nut on the alternator came off, so there was reduced tension on the belt. I'm surprised the belt didn't come off entirely!

    Did another No Limits night last night. 

     

    New Radiator was awesome - 82 degrees was max temp (even in pit lane) - No ducting or shroud on factory fan

    Forza brake pads were great - smashed them all night long - no fading - highly recommend them. Pretty good on the street too.

     

    Beat our previous best lap by 3.2 seconds on long circuit, and 2.1 seconds quicker on the short, so happy with that.....Heaps more to come.

     

    Check outthe video of my quickest session (second flying lap was the quickest - 1:14.2)

    What's your knock warning set at Mark?

    Or are you using the CEL for something else?

    Not sure if the warning is set. I have monitored the knock and it was under control last time out. The boost is spiking though, and I need to get it under control. I reduced the boost pressure to 1.0 bar, but you can clearly see when it spikes.

    No, sheetty old street tyres. Fred Flintstone had softer tyres. LOL.

    With some good tyres, it will be much quicker.

    What coolant are you running? I think I recall you saying you were only allowed to run straight water?
    I'm thinking of just running water and anti corrosion agent in mine. Ie water wetter.

    Had a think about this, and now makes sense. I bought the car with the Power FC already in and tuned. No idea if the CEL is for knock, but makes sense that it is. Can I check this via the hand controller?

    I'll take it for a tune before the next run, it's over boosting too much and too often. Needs to be sorted before something goes boom! If you wAtch the video on a big enough screen you can see the boost spikes up to 1.4bar.

    No doubt it will be. I think you can expect 2 to 3 seconds improvement right away. Most likely even more with additional seat time. Keep up the good work.
