You still have those!? I might have to take them off your hands one day.

But 1st I need a clutch, front brake pads and rotors, a new head gasket and a new bonnet to stop the head gasket thing happening again.

why not try a new intercooler. I reckon the cooler fins on the standard cooler are too tight and greatly reduce airflow. I'm going to by an after market big f*cker and put it on..

Scotsman should buy them and come along. He needs the practice..

I've already got a big Trust intercooler - was on the car when I bought it. I'm sure the problem I have is getting air our rather than getting air in.

Plus I'm looking forwards to you being a guniea pig and telling me how your car goes at Winton now because last time I was there it was overheating central.

Hmm, interesting Aaron. Maybe I should remove my rear diffuser as well. Uncle Benno knows best.

Although when Ben was telling me I knew what he was saying about airflow, but it still doesn't make 100% sense to me how something at the back of the car can increase engine temps (other than the air resistance theory), but hey if it works why not!?

you may have just saved me a few bob... I am getting a nice bonnet soon, the diffuser is no longer on the front or rear and the motor is now perfect.

Winton is the testbed....

You blokes just need to de-tune to 400KW and you'll be right.

that my friend is an urban myth

also, I can honestly tell you, there is no performance difference between 9.5 in rims or 10.5 in rims or the 265s or 285s. I've run every combination and they are all the same...

I have someone that wants to pick them up tomorrow but if you want them I'll sell them to you instead.

I have heard you suggest this before. And i'm not 100% sure you are right or wrong, but from my own testing:

When I ran 255/40/17" on a 17x9, I thought I could feel much more movement especialy in the rear on turn-in at Winton and didn't feel comfortable with what the rear of the car was doing. Then I went to Winton again 2 weeks later with 245/40/18" on a 18x9 I instantly went three seconds quicker without touching anything suspension wise at all.

I don't think the jump in size from 17" to 18" could be the differnce I found here, I always put it down to the baggy tyre moving about on the 17" rim. For me I felt I had much more confidence in the car when cornering as it felt more direct with the 18" slightly stretched across the rim.

Draw your own conclusions....

I understand... It's always best to have an excuse not to come to a trackday. Just not coming looks soft !!!

I'd say what you experienced is a slight enlargement of the testicles. With the size differences I have tried, there isn't even a few 10ths in it...

i say yes, but my bank ballance says no. i need new semi slicks!

besides im proli not gonna do anymore track days not in the 4 door. im looking for 32 GTR, so i might just wait till i have that...

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
