Steering wheel´s not on the wrong side, it is on the left side...

A matter a fact is that I think it is a little to low in the back and a little to high in the front. Talking a few cm here, prob not possible to see after it have been modified, yaa, maybe.
There is no contact between tires and arches/wheelhouses, but I get wind drag from the rear vallance lifting the car. It gets a bit nervous in high speeds, in the rear end. Front end is good at high speeds, but I need more camber for the corners. Mods will be carried out during the winter ie NOW!

Thanks!

I have a RHD Lotus Cortina to, I just wait until that one is finished and how many lampposts I will scrape...

I have the advantage of driving RHD cars in my work so I have practiced some during the years. But going fast in a track is not the first I will do in a RHD car...

[Dr Danger]

I still can't believe you let me drive those LHD Cosworths Bertil!! Very challenging driving on the opposite side of the car to what you are used to... :) Roundabouts in particular.

[Bertil]

Would you have prefered the Transit with the trailer behind?

I noticed at once you are a calm and serious fellow, so what´s the risk?



Talking of that day, my arm is still not what is was, but it´s gettin better.

[Dr Danger]

Me, calm and serious!?! Hahaha, got you fooled!

Might be time for a visit to the physio Bertil? If it's not better by now. For all those that don't know, I backed over his arm in a Sierra... :) See, not so serious now am I!

Hey, just out of interest, what LSD do you have fitted to the track car? Retains the Cortina axle but with an LSD right.

[Bertil]

Well, you seemed like a nice chap, and the house did not go away during the first 24 hours, so I thought it was cool to let you behind a Cossie wheel and go for a nice and calm drive (with 400 bhp under the bonnet).
Next time I will put you in the henhouse and only allow you to walk!

The arm is better, I did speak to a physiowhateverguy and he said only thing to do is wait for it to get well.

The LSD is and old fashion one with pads, not a viscous one. It is in a Cortina MkI axle, ratio is 3,9:1.

[Dr Danger]

Well, for what its worth, it won't quite have 400hp, but I will let you loose in the Cortina when you come over. :)

Yes, it was (very) tempting to come screaming past you in at least 2 of those cars but my calm demenor and perfect restraint prevented me from doing anything stupid! Phew!

Tried a 4.1:1 ratio in the track car? Or is Sweden like NZ and only got 3.9:1 diffs?

[Bertil]

Sounds great! I will tweak it up a bit when you are busy and then you can wonder why you never can go that fast! ;-)
Is the management system mapable in your car? Maybe an other chip and a set of injectors will do some good (along with a little hole in the hose)?

Sweden´s got both 3,9 and 4,1, the GT´s and the 1600´s have 3,9 and the 1200´s have 4,1. Most common are the 4,1.
I have not tried the 4,1. Since the engine reach the rev limiter set at 7000 in fourth gear easily I think 4,1 will be to low.

[Dr Danger]

The original Nissan engine management systems are quite tuneable but only with fairly specialized software and a dyno... However, after the nightmare that was changing the headgasket and messing with the 1 billion terminals and clips and sensors and whatnot, I have made the decision to go with an aftermarket system and junk all that other crap. Also, this will get rid of the airflow metre as they are a weak point on these things. So no playing for Bertil, unless you wan't to wind the boost up a little... :) I could potentially be making a LOT more power than now with some bigger injectors, a remap and a slightly bigger turbo... But why do that when I can go silly and do a fully forged re-build, aftermarket ECU, really big injectors, even bigger turbo... And I already have half the bits. :)

I was making a terrible assumption that many of the tracks over there would be quite short and thought that the 4.1's might give you a bit more pull out of corners. Are you running a 4 speed still? Time for that 5 speed maybe?
