So if it leans out, the tuner should have picked it up on the dyno.

My a14 did the same with twin su's 5500 max, I put in richer needles and now revs 7500. Would the a/f ratio lean out at max rpm if it is a lack of fuel problem.

My first ute I went to the local greens recycling to get a load of mulch. I asked the loader driver for 2 half loads. He said no and gave me a full load (of mulch), scary sight seeing a front end loader dropping just under a cube of mulch 3 inches behind your head. It was a very slow ride home and I have never been back.

My current ute is on the bump stops with a whopping 80kg. There is not a lot of travel down to the stops. It is still the best multi purpose vehicle ever though. Race car, daily driver, removal vehicle, plumbing ute, wheelbarrow for collecting firewood, chook s#@t, loading up garden waste etc, and my wife still wants me to get rid of it, see how she is tonight as she had to take it to work today.

I read it that if the car has been lowered before the 1st of august then it doesn't need to be approved. If this is the case as long as your car is manufactured before this date (you have dilivery of the car) how can the say that the mods were not done before this date.

Surely any suspension shop/fitters should be qualified to install suspension etc safely. After paying them for the install would you then have to pay to get it certified. Sounds like the politician/s may have some friends in the engineering business.

Hi Harry the exhaust is the same, thats the dorian timer you can see in the photo.

I think I may have helped the over heating by sealing off the whole front end and sealing the ic to the radiator now all the air has to go through radiator and ic(when I turn on the thermo fan you can place a peice of paper near the ic and it gets sucked on). It didn't get past 85 degrees although on low boost. I have taken off the oil cooler didn't like the hose clamps and the fact that it was a transmision cooler I will replace that soon. They have increased the hot laps from 3 to 4 plus the warm up and cool down, so 4 min 40 of flat out driving.

I too have had the turbo come off (twice) lost all your lock nuts and distroyed the gasket. I have now got some locking tabs from nissan (an oem part) if that fails a small tig weld tack on the nut and the manifold will stop them coming undone.

I am going to pull the diff apart before the next run because it is making a howling noise especially off throttle. I also have a heavy vibrition from the front left under light braking I have skimed the rotors re packed the bearings but have noticed alot oil around the damper so I have to pull that out aswell to check it out.

I have been speaking to some people about the same issues on the rb's a drain from the catch sounds like it might be the trick. Rb's would have to be the sweetest sounding engine on full song. There was a 260z with a rb25 in it as well as a couple of gtrs, what a noise.

I love this car even though it requires more maintance than RAAF jet fighter, my wife she doesn't have the same affection for it.

I'll pm you my address the lap top would be great as they sell avgas at the track I might be tempted one day to up it.

Great to see you guys had fairly easy fixes for the same problem, sounds like it may be a faily common issue.
I would like to get the engine checked first just to make sure.

It was raining then dry, then raining then dry all day. It was fun but slow in the wet 1.23min I had to be very carefull with the throttle a good experince though.

Unfortunalty a BMW rolled twice in colb corner in the wet, thankfully he wasn't hurt. It is allways sad to see someones pride and joy get damaged. This is the chance we take though and better to keep it off the streets.

I finaly got to give the coupe a proper run on sunday after fixing the miss and the turbo drain line. I managed to get a 67.1 on the final lap and ended up 3rd in my class, outright open and closed over 2 litres (1c).
I was running brand new bridgstones re55, what a tyre!

With a bit more practice (it was really the fist time I have driven it with anger around the track) I should be able to get into the 66's and if all goes well maybe the 65's (would have to be going very well). At the moment I am running 15.5psi on 98 ron 255 hp, Andrew was runnin 20 something psi on av gas 308 hp. With that amount of power I should definatly get my times down but at the moment 255hp is plenty.

The day was not with out it dramas though, I had only got 1 full go at 4 hot laps out of 4 attempts. The hose clamps in the ic piping straight out of the turbo kept on blowing off very frustrating. I had to replace the big fat clamps for skiny normal clamps. It managed to hold together for the last run.

I also have a problem with the catch can filling up somewhere between 1 and 2 liters so much that after the 5the lap the oil preasure light came on for a brief second whilst cornering. I will be getting a leak down test to try and find out why. From what I can gather ca's have a bit of trouble draining the oil from the top whin under sustained high rpms. I have a bit of work trying to sort out this issue.

Next time I will try and mount a camera of some sort for a bit of video fortage. It was great fun hauling in an 5.8 litre xy down the staight.

Can the attachments to the diff be moved in or out if so would this give some sort of adjustment to the stiffness.

I couldn't transport the car with the spoiler and the few spares weren't allowed in the car. I got a quote for $480 to truck a spoiler, diff center and a laptop. I plan to truck them over here but in the mean while I thought I might have a go myself at making one.

Is it worth carrying on with this spoiler it taken about 4 hours so far with a fair bit more to go(epoxying and mould making plus final product)? If so should I use square or round brake ducts?
