Why the need for a rewire?

Are you getting robbo to do the job again? He did that car not all that long ago.

He and Phil armour are the only two guys I know who have a good enough understanding of the motecs awd capabilities ( i know alot of people who hae tried and failed causing all sorts of damage) Have you considered talking to them about how the car was working before changing things or trying to improve on it ( knowing Phil and robbo I'd say that's not possible anyways)

If I was you I'd ask whoever is removing the loom to be careful and keep it complete, it would have been a tefzel/raychem loom that costs $1000's to have done. Robbo can be messy on some things but his quality of components is always top shelf.

Thanks for the advice... I agree with you 100% and am taking the car to Phil for this work, its already booked to go to him next month. I think he mentioned robbo as the guy who was going to help him do the work.

Reason for the rewire is that is has been a while (maybe 5+ years?)since the car wiring was done and there have been some adhoc additions

A complete rewire might not be required but we are seeing some intermittent problems with sensors and wiring hence I want to get it sorted properly. If Phil recommends a rewire then that's what it will get.

"Plan B" was to sell the old street registered car that was being setup as a track car and buy this one. The idea was to buy something that had all the goodies and a good setup and in the long term save some $$$... but as it turns out it wasn't so straight forward.

But eh, that's racing and cars!... its turning out to be a pretty major rebuild.

I'm hangin to get it out to the track but don't want to take short cuts !!

Good to see your using the right guys for the job.

A full rewire you'll be looking towards the 10-15k mark including engine loom and body loom but they will only use the highest quality tefzel wire, detusch connectors and raychem shrink tube.

Hopefully they can re use some of the detusch connectors you already have to keep the cost down.

We had a motec loom done in a GTR recently, wasn't cheap and the finished job was typical with some tidying up to be done but the quality gear was there.

Are you going to get Phil to tune it again? He always tuned that car when BSM were running it, between he, robbo and abe (the original engine builder) there is a wealth of knowledge about your car.

[Marko R1]

Is Phil a commercial tuner (I.e. has a workshop) or race cars only?

[Risking]

Armour runs a workshop that specialises in V8 supercars and the top end of the Motorsport market out towards Penrith.

Unless you have a high end GTR with motec gear and every component on the car is spot on your wasting his time trying to get a tune.

One of my customers who owns a very high end immaculate circuit GTR has his car tuned by Phil.

This BSM car was done by Phil back in its hay day. As was the sister car to it.

A lot of the Sydney based V8 DVS teams like sydney star racing, competitive production sports lotus' some Front running IPRA cars etc are done by Phil.

It's not a commercial workshop where you can show up and have a chat then get your car tuned.

Most people in the "domestic" market would never have heard of Phil armour. Most serious Motorsport competitors know who he is.

[JohnGTR]

Yeah, I've met Phil a few times, he is a good bloke and although he is very busy still helped me out with a couple things. I did speak to him last week and he said that he will book me in early-mid January.

I think this was a good GTR in its day and this rebuild is heading in the right direction but I am not aiming to be competitive at Superlap and just want to get out there and have some fun then see what happens...

I have had some exposure to a couple race teams and have seen what is involved to get a car to the front of the field. I do not have the funding or the time to go all out with the car but I want things done properly... UAS have done a great job getting it where it is and will be doing all of the major mechanical work, suspension setup and aero..

As for tuning, Dave at UAS has done the initial tune on their 2WD dyno and the car sounds good on the dyno (a lot better when it has compression on all 6 cylinders). I'm looking to take the car to a mate of mine, Jim at Tunehouse, to double check the tune and maybe have a play with the cam timing to see if we can get it to come on a bit earlier ... he can also check the 4WD operation on his Dynopack dyno. I'll ask Phil to give me a rundown on the Motec 4WD control.

Did u end up comparing back to back results of the previous low mount system vs your new BW?

[Duncan]

great idea to get the tips from John Boston, he knows the car backwards as well.

[BLACK BEAST]

Looking good John .

Nice Power

BW = Borg Warner??? No I've got a precision turbo...

I've got some old dynosheets from a dynapack dyno when the motor was good and I guess it would be a good comparison. I'll have to wait until I get it on the dynapack for a few runs then do the comparison.

Its going to be a different car once the suspension gets redone. The motor with a single will also give it a different feel but I agree johns input would be great...

[JohnGTR]

Thanks, I feel that the car is still 1/2 ready, suspension & Aero are just as important, if not more important than power!

[JohnGTR]

Quick update... now much work has happened to the car. It is now at a Motec specialist getting completely re-wired. I just have to stay patient.

Still have a few minor issues to address as well as address any problems following the re-wiring and then get to the track for some practice to make sure thecar is ok before the Nissan Datsun Nationals...

Cant wait to get it out for a run ...

Sorry guys, I've been a bit slack, here is an update...

After spending 5 days rushing to get the wiring finished, get the boost controller and Knock box setup and then get it tuned and spanner checked I towed it to Phillip Island for the Nissan Datsun Nationals for its first outing.

First session out, practically the first corner, it spat the power steering belt and it knocked the dry sump belt off. The warning lights flashed and I switched it off. It had a wobble in the power steering pully and it did fall off a couple times during tuning but we tightened it up and it seamed ok... not!

We put a spare oil belt back on and I took the car out for the second session without any power steering... not much fun. Hitting the apexes was pretty difficult and having no feel in the steering wheel was not confidence building. I only got a couple laps in to get a feel for the car before the session was red flagged. At least I got a chance to bed the brakes in a bit.

Third session I warmed the tyres up and then decided to have a go... First real flying lap it broke 3rd gear !! Game over.

All in all I got about 5 laps none at any real pace but if you asked me whether it was worth it .. the answer is yes!!

The car felt great under power and flat changing up the gears (using the ignition cut on the gearknob) felt fantastic.

The car has been sitting in the trailer at home and I've been restricted to playstation by the missus for a few months.

I will hopefully get the box out next week and send it to a specialist to get sorted but the guys in the know are telling me to get a Holinger.

[boxheadmr]

Unlucky John with the troubles at PI but with the new box i imagine it will be a weapon.

[JohnGTR]

Yeah, that's racing... just need to sort it out. Dissapointing that the PPG gearset seems to have given up!?!

The engine felt strong and as long as you keep it above 5000 rpm it was very responsive. Actually it felt quite linear powerwise which was surprising. It did not come on like a light switch. It loves to rev...

Suspension wise it felt good...not hard and not soft. Can't wait to get it out to Eastern Creek.

[Risking]

Hard luck with the box, that PPG has been the cars Achilles heal for years.

I remember the guys taking the car home after every race day to rebuild the box before the next days racing.

[White GTS-T]

Loving the build. Could you tell us a bit more about the cooling system setup that your running and also the pedal box/ratios your using?

[JohnGTR]

Cooling setup... PWR radiator and oil cooler.

Willowood pedalbox

Ratios ... not finalised yet ordering holinger... probably use their recommended ratios.
