Had this ss in for a few small jobs and dyno tune.
Had stock injectors and a few things needed attention.
Engine originally built by THR.
355ci 286 ft cam. Come Racing TTB. T5 manual.
3.08 gears. I fixed up the fuel rail install had some post all uneven with washers so made some to the correct size and one piece.
Re did the cross over hose
Had some old hose and fittings looked horrible and just wouldnt trust it.
Replaced with speedflow fittings and 200 series hose.

Next upgraded the injectors to 42lb bosch injectors.
Fitted some ngk plugs
Adjusted clutch cable.
Fix some vac hoses.
New battery

Hit the dyno and ended up with 240rwkw which is really good for such a mild combo and drives well too.
Tuned with the delco ecu.

Sat dyno a bit different today.
My own car on the dyno.
VX SS 427ci with g57 98 mm turbo.
If anyone remembers it made 1300 hp last dyno session.
Not bad but my goal was always 1400 min and people that know me ive said that was my goal.
So today pulled the wastegate off changed springs to get there.
Eventually my plan is to go co2 or on board air for boost control but thats what i have atm.
There were some small changes made.
Bigger motion raceworks throttle body 92-102 and plug change and moved to Race e85 so not at 77-80% anymore and fuel is a bit better and consistant.
Cam is a bit on the small side for a solid roller but its making the power i want and thats all that matters.
It also drives well has no vac pump for brakes so cant complain.
Ended up at 1452rwhp at the hubs and although its got plenty more im leaving it there as it really needs a 4 link rear to go any further.

Enjoy the video and if you would like to do something like this or turbo your LS feel free to msg on this page or call on 0410893148

Had this very cool VT clubsport come all the way from tamworth on sat.
The father and son trailered it to the shop for dyno tune.
Specs are
355 ci
S**t crank, h beam rods , forged pistons.
Comp about 9.8
Stock heads
Roller cam, lunati 226/231 duration @50 and 112 lsa
Stock manifold hpc coated and slight porting.
5 speed getrag
Std diff gears
Pacemaker headers ceramic coated
Twin 2.5" exhaust.

So being a new engine and still being run in i did some tuning under varying loads and some partial dyno runs.
Then changed oil and went that bit further and cut the oil filter open to check the filter. All looked good and everything was checked over.
Once i started doing power runs this one really surprised me doing a best of 249.3 rwkw which is the stock manifold record on this dyno. Most ive ever seen is 220 ish and 230 on a roller dyno.
This combo just works but it still has the typical fall off at 5500 rpm with these manifolds.
Test drive was great would cruise around with no bucking at lower rpm even 4th and 5th at 50-60 kph and just drove nice with plenty of power on tap.
Tuned on the factory delco ecu and factory maf sensor.
It also made an appearance at the all holden day which was great to see and the car looks great.

Had this vx commodore in for some serious uprgade's just recently.
It was a stock ls1 that had seen better days prob the dirtiest ive seen in a while too.
The good news is it already had a built turbo 400 and converter ready to go. The ls1 was removed, bay cleaned , wiring loom tidied up and in went a rebuilt 5.3 built here in the shop.
This is a budget build but has some good parts in it.
5.3 iron block
5.7 crank 24 tooth reluctor
5.3 Gen 4 rods ,arp bolts stock pistons gapped rings for boost.
Arp main studs
Ls1 sump, aeroflow baffle.
Mellings oil pump+ pickup girdle
Acl bearings
Btr stage 3 turbo cam 224/23x 618 lift 114lsa.
Colyes single row z chain ls2
L98/LS3 timing cover with turbo drain ( killa boost )
Gm mls gaskets 5.7
Arp head studs
cnc ported 241 heads
CHE trunion upgrade
BTR intake
1000cc injectors. Return fuel reg up front with boost ref.

Killa boost manifolds ( heat wrapped incl dump pipe and cross over).
Turbosmart 50mm wastegate
Gt 42 turbo , 4" dump , straight thru 4" dumped at diff atm will be getting a muffler or 2 to make it quieter and rear bar exit.
Aeroflow intercooler 600x300x 75
E boost 2 boost controller.

Also did battery relocation
Moved the astra pump to the boot and used a quick start module and put it on a led switch.
Relocated factory pcm inside the car.
Vz rad conversion
New water pump and lots of other parts.
The only thing that was never going to get us far was the 340 fuel pump but that will be upgraded soon.
The 1st thing was to crank and get oil pressure and then once running a base tune was loaded and proceeded to run the engine in.
With everything going well the oil was changed and filter cut open to inspect and it was all good.
Tuning time knowing the 340 wasnt going to go far on e85 i just tuned on gate presssure and ended up with 418 rwkw on 8 psi @6000 rpm.
I did a run and went 435rwkw at higher rpm but was out of pump.
The idea was to just do a 400kw tune now it can get finished up get some street klms and then come back for fuel system upgrade so we can really see some good gains.
For now its getting a couple things to finish off and the owner can go cruising.

For all your LS tuning and performance i can be contcted on the page or on 0410893148.

VX SS ls1 in for some upgrades.
Super clean example and very low ks.

The LS1 is completely stock apart from twin 2.5" cat back and 3.7 gears.

Baseline dyno was 200rwkw back to back which is not bad and our starting point.

Next i removed the complete exhaust system.
Radiator, header tank and hoses.
Trans lines.

Now with the mods we wanted to clean up the bay and also think about future upgrades.

A pwr cooler was fitted to modified factory cooler brackets.
Painted black.
Speedflow 200 series hose and fittings.
Heat protective wrap to keep the heat away from the hoses.
Also makes it alot easier to remove lines if the trans has to come out down the track.

Next was a full manta stainless twin 3" exhaust with hi flow cats and ceramic coated 4 into 1s.
These systems look great and sound great.

Next up since the factory radiator and fans were gone i installed a vz ls1 radiator conversion which both radiator and fan shroud with twin spal fans was powder coated black.
A big reason to go this way is to really clean up the bay as it looks great and its something i do with turbo setups as well.
New hoses were fitted and did the coolant hose bypass mod on the throttle body as no one wants hot coolant going through it.
There was also some custom wiring for the fans and a bypass mod so the warning light for overflow bottle doesn't show on the dash.

Next fitted
NGK TR6 plus ✅️
Granatelli hi performance leads✅️
Fuel filter ✅️
Vz Duspeeed otr ✅️
DBA T2 slotted rotors ✅️
DBA Street series brake pads✅️

Next on the dyno.
Ended up with 243rwkw a 43kw gain which is a good gain.
The car was also tuned for driveabilty and throttle response and tuned at varying loads and speeds on the dyno and then tweaked on the road and also tuned the trans.
The result is a car that drives great and gets up and goes and sounds great.

For all your LS tuning and modifications conact on 0410893148 or message through the page.

I can supply and fit manta exhuast systems.
Cam packages POA
Supercharger kits
Turbo setups and more.

VX calais on the dyno at night.
Done this over 2 weekends with some help.
The engine has now been in 3 different cars as both had an unfortunate end.
This engine made 184rwkw on 98 quite a while back with a boost issue which was later sorted but never went back on the dyno we just verified that the tune was good. Estimate would have been around 190-200 rwkw.

Basicly this engine was dropped in and i had to put box in, trans lines and finish the w2a install and a few things as well
as a walbro 255 fuel pump upgrade.
Fill with e85
Also new fluids and filters
New battery

Then dyno time.

Engine mods

Mace stage 2 cam kit with crow retainers.

3" pulley 6 rib
Walbro 255 fuel pump
E85

Twin 2.5" black ops exhaust
X force headers, hi flow cats

Great result switch to e85 picked up a bunch of hp at 239 rwkw @ 12psi.
Ready to hit the burnout pad!

Stock tb, stock maf tuned on the delco ecu.

VR clubsport came in for some much needed attention.
It came in on a trailer and it ran but was missfiring and really lacked any power.
The car had been sitting for some time at one point. The owner got it running and they did clean the tank out and put a new pump in.
Problem is the filter hadnt been changed and was completely shot. What was left of the filter inside was rattling around so basicly not filtering anything.
1 fuel injector was dead so i replaced it and it ran on all 8cyl but stillnot good. So pulled all the injectors out and they had lots of build up and corrosion.
I did try to get them cleaned but they failed the leakdown test.
So another set sorced 1 short and 2 were odd so i matched the rest and got them all cleane, tested with new filters and o rings.
Injectors in and new set of plugs.
Also fixed a few hoses and some wiring.
Checked over everything and checked timing etc.
The owner request a cat back system so i ordered a manta 3" with no resonator.
It looks 100% better than the rusted out original system which was also cut at the muffler and sounds great on these 304s.
Test drive went well and the owner was able to drive home and can now go cruising again.

If you need your 304 sorted, want to do some upgrades and dyno tune.
Call 0410893148 to book in.

VR clubsport on the dyno this week.
Came in not running and had a few issues to sought through.
1st was clean the plugs as they werent good just to try get it running.
Next was scan and diagnosis.
Found why its was runing so rich.
Dead coolant temp sensor.
Changed it out and checked it was reading correctly.
Next got it running and verified timing.
Injectors were also suspect as it just wasnt 100% so they were removed and sure enough bit of crap in the filters.
Had the injectors ultrasonic cleaned
and had new filters and orings installled.
While those were getting done i soughted the fuel sender.
It had been clocked wrong so didnt read correctly.
Also found kinked return hose and wrong size 3/8 hose on 5/16 fitting.
So replaced with proper 5/16 efi hose and clamps.
Fixed the pump install.
Fixed cluster sender. Fitted new sender and fixed the plug as it was super loose.
Next fixed the lights in the cluster which turned out to be a couple fuses.
Reco injectors back in.
New set of ngk plugs and began tuning.
Ended up getting the car to behave and ended up with 193rwkw.
Engine specs
304ci
Flat tops
230@50 ish cam
Std injectors
4l60e , stall converter i think 3000 rpm
3.08 gears.
Has a twin 2.5 into single 3" system

Really good result with 304ci and stock manifold.
