Yes the speeds shown aren't always related to what the car is doing. In the Karousell it goes from 90 to over 160, then back to 115 on exit.

I made a very conscious decision to keep my car a roadie with occasional track days. The focus was on making it fun on the road and comfortable.
Little things can make a big difference. I have V720 and rs4 tires for track stuff but they are harsh on the road compared to the pilot sport 4 and are a very noticeable firmness on the road I don't enjoy in the wet. I have had great times with tein suspension and added the edfc to control stiffness automatically based on G forces and speed. It gives a very compliant road ride and firms up enough on the track for me to live with it. My re003's are kept for the occasional drift day

The Garmin Virb camera’s GPS is only 1hz and a bit all over the place. I’ll post a RaceChrono snapshot which is linked to a 10hz external GPS.

Do you have any pics of your car? I’d imagine it would be very nice!

I don't know how to post pics otherwise I would share

Based on your description of the tuner I may be your man. I ran 177.3 rwhp with 2.5 head, Kelford stage 2 cams, 10kg flywheel, full exhaust, 2.0 injectors & running conservative timing advance in case of bad fuel. Tuner reckons there's another 10-15hp in the timing but we went on the safe side as it's mainly for road use.

Apart from cams just swapped everything over from 2.0 - 2.5 & dumped it in.

Another Brisbane 2.5 swapper, welcome on board Alan. Would be good to meet up and have a look at yours. I’m over in Samford Valley but get to cars n coffee most months.

Great power you made, do you know which cams yours were? I had a look on the Kelford site and could only find stage 1 cams. My cams came from Deckspeed and were their 2.5 specific road cam which I was told was a custom Kelford grind.

Which exhaust are you running and any plans for any track days?

I'm in Clontarf so not too far for a catch up. Unfortunately because of work don't get to the cars n coffee but sounds like I might have a couple of "headaches" coming up.

I couldn't find a cam listing when I looked so rang was told they had a set of stage 2 to the Deckspeed specs on the shelf. I'd have to dig out the spec sheet to see if is the same as yours although I suspect they will be. Seems only differences between us is I'm running drop mounts with heavy duty engine mounts and a full GWR exhaust - sport max headers, helmholtz with cat mid pipe & super Q muffler (had to #2 header pipe shortened by 10mm because was hard on the column... ggrrrrr - supposedly for Aus car! Meant had to get ceramic coating done again), I've removed the ERG valve and are running a high flow filter. My engine had done 70K and I thrashed it around for a 1000K before it went on the dyno to make sure the rings were free & sealing properly.

Tarin in Clontarf did my tune (Ecutek) & I'm thinking of going back & loading a 2nd map with the full advance so I can switch between them as required. He was pleased to hear I was using the 2L injectors because the impedance & response time is different to the 2.5L which would have meant more time on dyno & setting up - $$$$$$

Part of the build plan was to do a couple of track days but haven't been able to make it yet. Being a track virgin it's something a need to grow some & try it out. I have enjoyed a couple of "spirited" Sunday club runs so am looking forward to the day I make it.

I read in your later posts that you don't like your clutch pedal. Mine was really low after the change & I can tell you lengthening the pedal pushrod is a PAIN. What I found invaluable was to use a 10mm brake hose spanner (heavy ring spanner with split for pipe).

I'm still not entirely sure it isn't me adjusting to the different clutch travel following the engine swap. There's no issues when road driving so I'm reluctant to pull the box and do a full strip down at this stage.

I had similar issues a while back after a clutch swap to find there was an issue with the spigot bearing. RE the people who can fix standard seats to take a harness, where abouts are they and how much do the charge mate?

I’m going to pull the box soon and check everything out. I did fit a new spigot bearing when I did the engine swap but the symptoms are similar. I also have a new set of plastic bushes to fit in the box as well.
I must admit I’m not looking forward to it as I found undoing the top gearbox bolts to be a right pita.

I think I’ll go back to Tarin shortly too, now I’m running a free flowing midpipe and muffler it feels like I’ve gain a few extra horses, I’d also like to try and smooth out the low revs but overall I’m really happy with how it turned out. I’ll let you know when I’m planning on being over at Tarin’s so we might catch up.
Re the clutch pedal adjustment thanks for the tip. Ive been upside down under there checking it out and it looks very fiddly!
