My circuit racing set up VX GTS - Part 1

[macca_779]

I have entered the GTS into the NT Drag titles for something different. Qualifing tonight so run 2 x 13.8 at 104mph. Slow I know but such is life

Couple of photos and a couple of new mods just completed

Hey Listy just a heads up mate, but that's the wrong sticker for your isolator. Plain blue is for the battery location. Blue with a red spark is for the isolator.

Cool and thanks for that. It was just a temporay thing as i had no lighting stickers. I have a set on order so will be here by the next circuit racing meeting next weekend.

Ended up winning the street class in the NT Titles DRAG racing last night (yes that is drag racing) . Bit of a suprise for sure.

The final there was 5 seconds wait until I could leave. HUGE chase down but just got there in the end with some pedeling as I felt I was going too quick.

Few photos of the GTS away from it normal habitat







And the times from the drags the other night somehow winning the drags

Went circuit racing on the weekend and set a new PB of 1.20.88 which is great.

BIG downside at the end of race 3 the engine went boom in a big way. Huge amounts of white smoke.
I checked all the data from the LM2 and oil pressure, engine temp and the basic tuning all read perfectly normal so in short engine internal failure.

So it is getting the heads off (again) to see what sort of damage is involved. This time I will buy new new engine as this only lasted 6 months before boom.

I hope the heads are ok so it is just a short block one for one and away we go again.

Video of the smoke when it let go. I have another vid of inside but have not uploaded as yet.
There is water all through the oil too so block is split too I guess
Bloody annoying but it was just internal failure.

The video is cut short as the misses thought I had a huge off and the kids were hanging off her.

Sorry to hear mate. It's funny how you set your pb just prior. I'm a firm follower of the belief engines always run their best just before they let go. Be interested to see the cause when you find out.

Unlucky mate, it's funny with engines how when the numbers look good they fail. Coming into a hairpin a bit of load down changing and pop, maybe a small fracture in the block/cast deficiency finally let go who knows.

I've always raced by the four rules,
1. Race it
2. Break it
3. Fix it
4. Repeat

Yes hear that.Number 6 piston was dead, broken conrod, split block etc etc. Not sure on the heads but one side would be no good atleast.
I ordered a long block ls1 today. It is a complete long block so will be all done ready to install including all the normal ls1 upgrades like cam, oil pump, springs, brand new rebuilt engine etc etc. Has 12 months warranty to go with it too which is good.

Saves changing all the gear over from the old engine as labour is the killer doing that.

The engine in the car is dead so not worth even recoving. Still plenty of stuff will be still fine and I will sell it off like last time.

I am giving the local tuner a go too as the engine builder will warranty the engine including tuning if I get the tune done at this shop. That is a good thing.

So 2 weeks to build the engine, 1 week freight and 1 week to install so if all goes to plan it will be ready for run in in one month.

Hope and see.

My other project is going well too for my sort of drag / street car for next year. Nothing serios but just something I wanted for a while. It will be blue soon but wrong badge so not not much point putting up details

Photo of the engine might pass through.

[zorro]

Is that a Cortina?

[Jake235]

Looks like an XD/XE? Awesome, def post up some details!

[HSV Listy]

No worries.

Pretty simple plan.

It is a XE Turbo original from Ford (aftermarket option from new) Fuel injected
170 000 orig km
Perfect straight and rust free body
5 speed borg warner manual
Several upgrades already done like suspension, alarm, central locking, air shocks. Similar to the fairmont upgrades plus extras.

Mods in progress are:

Custom modified EA intake and exhaust manifold to suit turbo.

New Garret TT37R 600hp rated turbo. Pretty big but will run about 450hp at the engine. Planned output 400 to 450hp at the engine

Custom piped intercooler

High flow injectors and high flow fuel pump

High lift turbo camshaft and upgrade timing chain / dizzy arm

Extra heavy duty clutch

Aftermarket ECU to run it all. Basic though.

It should run low 12s.

Already done is the DJR grand prix kit fitted, rear disk brake upgrade, LSD and 3.07 gear ratio. New Wheels are identified and found. Not purchased or final decision yet. Should be 10 or 11 inch 295 rear and 8.5inch 245 fronts.

Next job he is to finish the intercooler plumbing, take the engine out, clean and do the cam, timing chain, rings, bearings etc. Basic rebuild.

Full respray inc engine




Once the paint is done and sticker kit put on it will be similar too the below. Slightly different blue though

Sorry to hear that my old engine broke a rod!
What sort of rpm did you rev it to?

Also surprised at the low mph it was running at the drags.

[HSV Listy]

It never made power above 5500 as the tune was never right and for some reason it just flatlined over that RPM. Most i used was 6500 but the limiter was 7000.
I hope now I can use a local tuner we can nut through it and get proper power out of the set up. From reports the local tuner blokes are better and the engine maker will warranty the engine with the local tuner (yes on paper too)

The engine should make 300rwkw with the good flow heads and the cam is a 234 243 high 500s cam, duel springs and 7000 rpm limiter. Pretty lumpy too he said.

[dyno junkie]

Ok that explains why it was so far down on mph in the quarter.
I had the limiter set at 6,950 with gear changes at 6,800 as that was where it was making power.

[HSV Listy]

The car is back on the road. Just waiting on the tune now. Booked in next Thrusday but next week I am getting the spoiler repainted and cleaned up.
Install was right on budet. Considering all the alloy went back up the intake and went through everything they mechanic did well. The internal of the engine was a hell of a mess. Internal are distroyed.

The round chunks are the left over of a piston.

[HSV Listy]

THe new engine is all in. I ended up getting another local tuner to do the tuning and he was willing to do some reading up on the LPG. Better than the mob that just put it in the too hard basket and could not be bothered.

He checked out things, got some readinsg and found a issue with the LPG and Petrol injectors. Some of the LPG injectors were firing on petrol and also when on LPG the wrong injectors were fiting. One was not firing.
So the LPG computer has been sent down to APS for futher investigation to see what the issue is. No LPG to a cylinder when there was supposed to be is not good when you are on full belt on a circuit.

I am also getting the front spoiler repainted and a but repaired while it is off the road. Also getting some mounts made up so I can put the front diffuser on I got made up. Bit of aero

Cheers
