Cheers brother much appreciated for all the work you do

[@cassarindustries_wheelwerk]

Always a pleasure bro

This is just what the doctor ordered...as you know i gotta do the tailshaft in my misses car,good to see what im up against up under there

[@smittywerbanjagermanjenen3912]

Oi mate, just ordered me a SIDI OTR CAI for my 3.6L Caprice PPV! I’m Stateside but I love this Aussie community and your cars. Boy are parts hard to get over here though

[@cassarindustries_wheelwerk]

Nice one mate! Really appreciate your support in watching the videos. Hope it all goes well. Just keep in mind there is about a 50% chance that I might turn the engine light on after you install it. If it does, it will throw a code for lean mixture at idle. It’s not the end of the world of that happens

[@jaywitts6941]

great video, informative and entertaining, keep it up

[@cassarindustries_wheelwerk]

Thanks legend

[@mr-stray]

Hey mate, love the video and appreciate the in depth information in regards to it. I was just wondering if you'd happen to know if the exhaust would comply with NSW laws as I know NSW is very strict when it comes to modifications

[@cassarindustries_wheelwerk]

Really appreciate it mate, thanks heaps. I’m honestly not sure as we’re in a different state. But if you were worried there are other exhausts available that have quieter options. Good luck with it

[@D800Lover]

I had the Orssom OTR AI as show in the video and fitted Xforce 2.25" catback exhaust. It was put on a hub type dyno and when tuned it got to 190KWrw. I note that you got 207KWrw. Does the fact that the dynos were different types make a difference, roller versus hub?

[@cassarindustries_wheelwerk]

Every Dyno is different, and every engine is different. A Dyno is a tuning tool so even 2 Dyno of the same brand will read slightly different.

[@D800Lover]

@@cassarindustries_wheelwerk - Thank you. Still, I wonder about a couple of variables. (1) I see some have a fan on front of the vehicle on the dyno and especially with a direct OTR air intake, how would that affect the performance - some don't use fans. (2) What if an E10 fuel is used, 94 Oct and naturally aspirated engine LFX? (3) The temperature, particularly if we are closer to 30C than 20C. Do these affect the output shown by the dyno and to what degree?

[@cassarindustries_wheelwerk]

All do affect it. I find generally vehicles run on a Dyno with a cooling fan infront will make a couple extra kw as it cools the air. The colder the air, the more dense the air is. The more dense the air is, the more power it will make. Hence why also vehicles run on a dyno with a colder ambient temperature will generally make a bit more power. E10 you will only see gains if the car is tuned for it. But NA engines don’t gain too much. Boosted engines run on E10 and tubes for it will definitely see gains

[@D800Lover]

@@cassarindustries_wheelwerk - Thanks. I find this interesting. You have confirmed what I thought re fan and cold air, although the fan would not actually cool the air, but compress the air and hence achieves a similar result. The thing is the question of E10 94-95 Oct fuel. These LFX are naturally aspirated engines where the extra cost of high-Oct fuel is mainly for turbocharged engines and should not be expected to be used in n.a. engines. But of course there will be plenty that swallow the line that you must have 98+ fuel. Where is the advantage there as the price difference can be significant over time. So get your Commodore VF SV6 OTR intake, cat-back exhaust, fill it with E10 fuel before getting a tune. What do you think?

[@cassarindustries_wheelwerk]

Yes correct. However the gains to made from running E10 wouldn’t be worth it. You’d barely notice the difference in the street. Plus not a lot of places sell E10. Ontop of that if for some reason you don’t drive the car for a little while, E10 goes off very quickly and crystallises which kills fuel systems.

[@MelodyMan69]

Did you re tune the engine ecu to match the changes? Any MAF Fault Codes.?

[@cassarindustries_wheelwerk]

Some throw a code and some don’t. This particular one was fine for around 10,000 km but then there a maf code, and mixture lean code. Soo the customer has the time done. Big have can be had with these mods and a tune

[@acarzia5580]

Have you had any issues with the Orssom intakes? I was thinking of getting a VCM one and just modifying it to fit on the ltt engine as they seem to be a bit better quality?

[@cassarindustries_wheelwerk]

It’s the third one I have fitted and have not had any issues. They seem to be of good quality and like the vcm intakes, they also have a k&n filter

[@acarzia5580]

@@cassarindustries_wheelwerk Thanks, do they get enough air though? Because they seem to just sit on top of the radiator as opposed to actually going over it.

[@cassarindustries_wheelwerk]

The get more air than the stock air box does mate. It draws air from over the top of the radiator (OTR mean over the radiator) and gets fresh air from behind the grille essentially

[@kustombuds8473]

Hey mate any videos of changing cam intake sensors or replacing O2 sensors got a 2010 series 2 sidi 3.6 throwing up intake cam sensor and o2 sensor and also a abs light saying stability control anyone have any help cheers

[@cassarindustries_wheelwerk]

Sorry to be the bearer of bad news but My guess would be you have stretched timing chains mate. When the chains stretch the chains they throw fault codes for the can sensors. It also can cause the engine to run lean which would throw the O2 sensor code. Very common fault in those engines see at least one a month.

[@markgough6378]

hey mate what brand cat back exhaust was that . like was it from online or from a local shop sent to you ? i dont think i heard you say the brand

[@cassarindustries_wheelwerk]

Hey mate. Dea performance available through Dandenong exhausts

[@topfootystar7529]

Hey mate where did you get the intake from

[@cassarindustries_wheelwerk]

Orsom intakes. Check em out online and they also have an eBay store

[@bananasplit4554]

Hey mate where can you buy the Otr intake for a v6

[@cassarindustries_wheelwerk]

Just off eBay mate orsom have an online store

[@AUS-_-MADDOG]

Hey mate will that otr fit on a ve v6 omega commodore? Cheers

[@cassarindustries_wheelwerk]

It will but there’s a slightly different one for a 3.0lt

[@51Faces]

If I understand correctly, the MAF cord IS long enough, just restricted by the tube?

[@cassarindustries_wheelwerk]

It’s restricted by the tape in the loom. So you can just untape it back to where it’s run up into the factory loom, and then you will have enough length. Then just retape the loom

[@user-dg3df7pb3w]

Hey mate loved the video 👍 how’s that exhaust sound now that it’s settled in? And have any further mods been added?

[@cassarindustries_wheelwerk]

Exhaust sound’s completely different now. Had a bit of carbon build up now and sounds much deeper and less farty. No more mods since this video

[@mahiaporter]

Hey mate, how do you take off/move the positive terminal to lift the airbox?

[@cassarindustries_wheelwerk]

There’s a little tab at the back of it that you need to pry across with a small flat blade screwdriver. Then you can lift it ip

Non idea sorry. They were already on the car when my mate bought it

From memory it was around the thousand dollar mark

[@D800Lover]

@@cassarindustries_wheelwerk - Thanks. That would be about my budget. Got a MY17 SV6 Wagon last week. Took the Orssom OTR out of my old MY13 and will be fitting that. But when I have exhaust and OTR fitted, then I will have to get a tune, so how much cost would that add?

[@cassarindustries_wheelwerk]

@D800Lover could have been less than that mate I can’t exactly remember it was a long time ago. I’d expect you to pay anywhere from a grand to 1500 for a custom tune but speak to someone local to you who does tuning as everyone charges differently

[@D800Lover]

@@cassarindustries_wheelwerk - I note that some do 'remote' tuning. Also that you can do tuning after an OTR is fitted without Dyno. But I suspect that get you a guaranteed improvement by not the final optimisation to get the absolute max possible, right?

[@cassarindustries_wheelwerk]

@D800Lover proper way to tune a car is on a Dyno. Every engine is different, regardless of how they are built. In a perfect world any modification you do will enforcer more if the car is tuned, but there are of course benefits that can be gained by doing bolt ons without tuning

Pretty sure it’s LLT. I think LFX is in the VF

@@cassarindustries_wheelwerk lfx was in s2 VE's & WM's from 2011

[@Judge-v8s]

Did it need a tune after installing the OTR ?

[@cassarindustries_wheelwerk]

On this particular one, no. But I have had them in the past where I have fitted these, and after awhile, they do put the engine light on and throw a card for the fuel mixture correlation. If that’s the case, then you will need to get it tuned if you don’t want to put up with the engine light coming on

[@stugats77]

Do you need to tune it after you done the mods?

[@cassarindustries_wheelwerk]

No necessary, but definitely recommended. Some cars will throw the engine light on after doing the intake, but some don’t

[@satisfactory3368]

What other cheapish mods can be done to a sv6 ve like this one ?

[@cassarindustries_wheelwerk]

Cheapest mods there aren’t a heck of a lot. Intake, full exhaust, and a tune will really transform it. Other than that changing your diff gears to a high ratio will really wake the thing up and make it get off the line heaps quicker

It’s not the oxygen sensors that’s the issue. The engine will physically run lean at idle, throwing a code for lean mixtures at the O2 sensors

That's sounds sooo bad for a 2.5 inch catback sounds cheap...... maybe xforce would of been the way to go

[@cassarindustries_wheelwerk]

All mild steel systems sounds similar to that when first installed. I’ve fitted mild steel xforce and it’s pretty similar. After a a few hundred km the exhaust sound changes quite a lot.

It really did at the start! But once it got a bit of carbon buildup in the Exhaust, it actually wasn’t that bad
