It could be fun, just get some slip angle going on the trailer.

 

Consider myself outed... All part of the learning experience

The yellow Cayman was Geoff Sarney.

 

As Sam mentions if I could find a proper race trailer that some one would hire then I could take the 2 sets of track wheels that we need to get to QT - save the cost of courier.

Anyone have any contacts with race trailers in Chch that wouldn't be needed 19 - 27 March?

 

Thanks for taking the time to find it Matt. When you write this many posts you sometimes forget whats been said....however just want to point out at no time was the debate about your 964 Vmax on the straight (you did volunteer the information which was interesting and in hindsight consistent with Johns 193-196 statement). We were debating the 996.2 GT3 Vmax after you just got it. Paul was up at 220-230 and I was debating that suggesting closer to 215. I suspect although time has moved on and the car is now likely quicker than when you got it that you will be Vmax around 220kmph on that straight these days?

As a point to note and I guess Paul will clarify this through his experience I shouldnt think the Vmax on the 993 is able to go beyond 200 kmph on that front straight at HD assumes track tyres and a 1.18 tyre lap time drive.

Remebering that there is roughly 22 bhp between a 993 and 964 at the same weight thats 4 kmph difference in Vmax. There may be a fraction of Cd involved but we cant measure it nor wind speed & direction.

John if you are at 183 when you should be at 193 and you feel its not your exit speed then you have a bigger problem than that piece of paper saying you just won the 20 bhp lottery.

I go back to the ducktail, positive pressure pocket, IATs, etc

Yes a Dyno session is the only way to sort out what your engine is making and as previous post have made some recommendations for that also. A before and after chip analysis proved very educational to me and also allowed me to see what changes the revisions Steve Wong made to the chip changed in terms of the relative output (I had it dyno'd between each revision).

John. Its your car mate. The AIM has been telling you the data and you bum has been telling you your loosing power in the afternoon sessions. Something aint 100% right. I assume youve tried other C4s for comparison. What about asking Steve to tell you if he noticed being down in power when he drove the car?

 

Michael is as hard as it gets - racing seats, track tires, US spec 'bull bars', 2 crashes and on a percentage basis his 'over capitalisation' even puts you to shame.

Michael is an inspiration to us all............

Why don't we do a dyno day.

I was planning to do one for the 993, maybe we should do a group secession one morning and see if can get a group discount?? Just putting it out there?

 

Cant play without them Macca
..Munted back,3 blown discs, and a cage in the neck combine to create interesting pain groups.. Tramadol lasts for about 16 holes before I start to feel too much.. God knows how I would come out of a nudge like Chris's..... on all 4s probably.. As my Dad once said, I'm to scared to have a crash..
He was one of two drivers not to spin in a NZ GP, the other being Stirling Moss, and the interviewer wanted know 'how come'? He was driving his 250F Maserati so must have been a handful

 

Just looked at my AIM database. Firstly, seeing the original post the 190 km/hr times were on the hand held radar, not the AIM.

On the AIM I have a best recorded lap for Peter, Steve and me, where the top speeds are 183 ~ 186 km/hr. The time differences are not due to the main straight speed, it's the corner speed.

 

Phil. My wife wouldnt mind talking to you about that at some stage. She has a cage in L5, seems failed fusion/graft that we believe has creating some compression of the sacrum region which leads her to live her life in constant aching and pain. It may be the pedical screw inserted into the vertebrae that's causing a pinching of the nerves but the back specialist (Howie) cant shed any light his job is done....your experiences may help her.

 

John. Its good to clear that up (I think?).

 

It is. Data is King. You may be able to go faster up the main straight in a 964, based on the starting point in the sweeper but what's the point if it's not going to be a fastest way to lap?

 

This may be the most obscure video yet, but I wanted to tell a good story. Brian at Mega Tyres has a touch less tyre machine (touching rims). He cares about doing it right and had no problem with me watching. The Fuchs are still immaculate.

 

Sorry John. That aside what was the difference between your car Vmax and Petes for example? Werent we trying to establish why there was a 10kmph vmax delta with your car? One would assume Steve can exit the sweeper as fast as Pete so interested to know if you still believe you are down on power....

 

We have two data sources, hand held radar and AIM. We could assume that the two are equally accurate, but I prefer to rely on the AIM.

I find it hard to believe that neither Peter nor Steve didn't extract the best out of the cars up the main straight. Until I have AIM data of another 964 going faster up the main straight AND having faster laps than Peter or Steve I'm calling my engine as ok. However the WOT microswitch is on the pre SITT checklist. I'll post the traces later. Right now I need to commune with family.

 

Here are the traces. Steve 1.19.57, Peter 1.19.72, me 1.21.448. Main straight speed is not markedly different, it's the corners. No surprise there.

As for WOT, I just used my Scantool and confirmed that WOT is not triggering. It should trigger at 78% of throttle travel. I will see if I can adjust it.
