I found myself a 2nd hand computer, a Haltech E6S.  It's very similar to the F9 I'm running except a few years newer and with ignition control which is what I was looking for.  It should do everything I need and was a LOT cheaper than buying a new one.  I think I'll leave it until the end of this season to install it though.

What number is on your induction manifold?

Mine looks like this (not my car btw)

I'm not sure of the number but I'll have a look.  It's just a standard Australian 280ZX manifold with the webbing cut out of it and the inlet modified to suit the larger throttle body.

I thought the webbing was cut out.....That is what the difference is....I wasn't sure if it was another inlet manifold or modified.

Makes it sooooo much easier to get the nuts tight on the manifold.  I remember getting the manifold onto my old R30 Skyline was an absolute nightmare!

In other news, my car is now engineer approved and registered on special interest registration  ;)

Congrats Scando! ;D

PS, cheers for the webbing trick - might have to do that on mine.
You havent noticed any cracking?

Might be able to come for a cruise with you guys on the next tassie tour now  :)

Haven't noticed any cracking.  The prevoous owner did the modifications on the manifold many many years ago so I assume it would have cracked by now if it was going to.  I think the webbing is there more as a heat sheild than for structual reasons?

Yes, Shrek was where I got my inspiration from.  It puts out 3 rwkw to align with the 3 Shrek movies ;D
Glad to see you found your way here mate.

Just found this video on youtube.  It's incar footage from one of the R32's I race against from round 4 race 1 at Symmons Plains following me.  You can all laugh at my massive understeer and then oversteer through the hairpin for the first couple of laps.

Hahaha...didn't look that bad at all! That R32 catches up to you a couple of times under brakes. Great run though...should be great to see and hear some in car footage in your zed...I wish they had starts like that in the MSCA events.

Yeah, looking at that I realise i was being a bit soft under brakes for the first couple of laps  ::)

The little cameras the guys are using are only $270 so I'm looking at getting one so I can post some in-car footage from the Z.  I've got a birthday coming up soon, might have to start dropping hints to family members  ;D

I had a good weekend, finished 2nd for my class and now have a decent lead in the series.

Had some great races with this Evo:

And this Commodore:
http://www.circlewor...9/HQNAT&start=0

Had a wet final and worked out a little setup trick to make the car work in the wet with the locked diff.  Was about a second a lap quicker than any other 2wd car including the cars in the class above me  :)

Would that be the disconnect the front sway bar to really soften the front end up trick? That works a treat for me.

That's the one  ;)

Last time I drove it in the wet it just wanted to go straight ahead at every corner with the welded diff.  With the front bar disconnected it was magic.

Would you get the same effect if you had an LSD fitted? I'm sure the LSD behaves the same as a locked diff under power..

Not really, with a locked diff even when you are under brakes it wants to push the car, where as most LSD's will effectively "freewheel" when not under power and will not push the car all the time.

A car with nuetral handling and open or LSD diff will have turn in understeer, and plenty of it, when fitted with a locked diff. To fix this I have set my car up accordingly, ie neutral handling with the locked diff. If I change to an open or LSD I would have to alter the set up my car so it won't be a huge oversteerer, not a small job as I don't have many adjustments. I'm a great believer in KISS and not allowing anyone to play with the car. I have it set up where I am happy with it and I can't really alter anything but shocks, as I run Koni adjustables and the general alignment, which is only checked and moved back to where it should be at the start of a season, or after a major off. My ride height is fixed by dropping the spring seats down the strut and re-welding them, giving me a fair drop in ride height, but still with the standard spring height and shock size to allow for effectively the full spring travel of a standard set up without carshing onto bump stops all the time.

For wet weather racing you generally a softer car, depending on the amount of water on the track and the time available to make the changes, I generally undo one side of the sway bay, I only run a front bar as I want the rear to wander a bit, and soften the shocks.
