Ok, I guess I'm the first again here in Australia with a modification that's 'different'  :cry:

I'll refill again tomorrow and see how much a free flowing exhaust helps with economy on the highway.

Thus far, very happy with a $280 mod that looks factory stock, sounds quiet inside at legal speeds, yet has a growl under boost/acceleration.  

Forgot to take the camera with me when the exhaust was fitted. Will grab some photos tomorrow.

As sort of "co-founder" of the site you're promoted to "member of the month for May" for that posting...

Can't wait to see the photos  

Cheers,

I love to tinker, can't help it.

Hey Thumper,
Your doing exactly what i wanted to do, and i must say, those results are surprising!!!!

can i ask a favour however, if at all possible can you take a video of insite the car with some normal acceleration and then gun it from stopped and from rolling, would love to hear this exhaust for myself before doing the change to my own i30!

also very interested inf uel consumption, one thing that would turn me off doing this, but it doesnt seem to have affected your car all too much (and im sure you were leadfooted after doing the change <img src="{SMILIES_PATH}/icon_e_wink.gif" alt="" title="Wink" />)

thanks in advance!

Congrats on our first recipient

[Thumper]

Yeah, I was enjoying the newfound 'extra' torque that comes from a freer flowing exhaust and turbos!  

Will see what I can do for a video.

When I had the exhaust made, I made sure that the old one can easily be bolted back on. (Nothing on the factory exhaust was cut) 10min job, tops, to change back to the stock exhaust.

EDIT: Modder of the month, LOVE IT!

Ok, just went for a little drive on 'private property'    (Though had some wheel spin, sadly)

Rolling start from 40km/h is where it shines! 3.40 seconds 40km/h to 80km/h

Took some video and audio of the new exhaust, honestly, it sounds like a WRX with a stage 1 sports exhaust. Has a nice 'burble' to it, from outside.

Encoding video for you all now.......And making a coffee.

 Though had some wheel spin, sadly  

Do you have ESP.  If so this should, I think, prevent wheel spin.

[Thumper]

eye30, no ESP on mine.

Ok, is of the standing start. (Private road, of course)  8-)

[eye30]

well good and sound not to bad to attract attention of Police.

140km's = 90 mile per hour.

In Uk speed limits are:
Urban 30 mph (50K) sometimes 40 mph (65k)
non urban 60 mph (100k)
Dual carrageways 70 mph (115k)
Motorways 70 mph (115k)

so 140 k's is normal speed on uk motorways!

What is the legal limit by you if you have to use private road to test speed.

[Thumper]

Max here is 110km/h (About 65mph) on the open highway. (NT has a 130km/h limit on the open highway, it was unlimited for years. Oh the joy! Then the PC bleeding hearts came and wrecked it for all. Now the deaths on the open road have DOUBLED since the speed limit was introduced)  8-)

As for the sound, yup, quiet, has a note only when your on boost, nothing that would attract the wrong attention. Interesting note, from such a small diesel, though, isn't it?  

[tk421]

Do you have ESP. If so this should, I think, prevent wheel spin.

I don't think ESP would help the cause. Mine has operated on a couple of occasions and it functions for greater control, but would have hindered the acceleration off the line.

Great Vids, Thumper

[eye30]

Point taken but ESP may counter the effects of wheel spin if the module detects a potentail skid senario.

Extract from Wikipedia: (ESP also known as ESC)

Electronic stability control (ESC) is a computerized technology that improves the safety of a vehicle's handling by detecting and preventing skids.  When ESC detects loss of steering control, ESC automatically applies individual brakes to help "steer" the vehicle where the driver wants to go. Braking is automatically applied to individual wheels, such as the inner rear wheel to counter oversteer, or the outer front wheel to counter understeer. Some ESC systems also reduce engine power until control is regained.

[Shambles]

Hard to believe (from the 2nd clip) that it's a diesel.

Great vids, thanks for sharing <img src="{SMILIES_PATH}/icon_e_smile.gif" alt="" title="Smile" />[/size]

[tk421]

eye30,

From my experience, it’s not a smooth process. It pulses the brake applications, and feels like a series of little skids rather than smoothly limiting wheel speed. You’ll certainly know when it’s operating.

Both times it happened to me have been when I was accelerating from a standstill. So it was the brakes operating on the front wheels whilst power was applied at the same time - not a good combination.  

[Thumper]

Thanks all.  

I like it. It's different. Will make people think "What the, what the heck is in that?" and will not attract the 'wrong' attention from the boys in Blue.

As for the acceleration video, I'm surprised that all test show the i30 diesel can only manage 0-100km/h in 12-13 seconds. Mine has felt alot faster and punchier than that from day one! (Maybe because it was a demo? One that has been booted from day one!)

Anyways, I'm more than happy with it.  

[encountar]

Wow.. seems like a brilliant mod from the look of those acceleration times, thank you very much for posting videos !

I cant watch them yet (work computer) but will be the first thing i check when i get home.

Picking up my i30 on sat.. waiting on the loan to settle, should all go through this afternoon and i can get my car first thing sat morning (damn working afternoon/night shift!!!)

[LeeUm]

Sounds very nice. Does it drone at all when keeping a constant rpm say at 70km/h? Does it void the car warranty at all by changing the exhaust?

[Thumper]

No drone, very quiet (Stock quiet) inside. Nothing like a petrol engine with a sports exhaust.

In fact, the wife hasn't noticed any difference in sound (Inside) but said it feels smoother, and more powerful. I just replied that the engine must be freeing up!  :roll:  So, from the back seat I mentioned "Just tickle it, you'll be fine. Pick that gap!" With that she put her foot down and sling shotted through the gap in traffic.

Her comment "Wow, goes better with three people on board."

Little does she know!  8-)

If there is an issue, I can just bolt the original exhaust back on. 10min job.  

[Dazzler]

Who's a greedy B....r (think he's trying to get the award for June as well)  

Thanks for sharing (and going to all that trouble...)  

[encountar]

Wow thanks for the vids!!!!

loving the sound of it

[jamiec]

Wow that seems to be a great mod for the crdi. being that it performs
alot better with less backpressure it should be more economical when driving
without the leadfoot. I am waiting and hoping that the economy is better.

I had a toyota corolla turbo that i put a high flow exhaust on and performed better
and had better economy without leadfooting it

[Dazzler]

Hi Jamie (From Burnie Tas - He's only 50kms away from me)

Have you had a drive or ride in an I30 yet? We'll have to catch up soon. My I30 will seem a little boring compared to Thumpers (and some of the others!)

Cheers,

Dazz

Do you like the new site?

[jamiec]

G day Dazz
 Yes i had a drive in an i30 crdi manual a couple of weeks ago as i had seen one
 at the dealers on my sometimes nightly walk around the local area ( dealer is only two blocks
 away) so thought i would go in and test drive one. very nice car it goes great for a 1.6l motor
 only problem was test drive to short

jamie

[Waja]

daym, the revs are staying high while you were drivin! but yeah! i love the sound of it, esp since you can still hear the car all the way down the other end of the road! haha, great work thumper! funny watching your avg fuel counter just tick up by .1 though! haha...

[Thumper]

Yeah, wrecked my average by .1lt/100km  

The sound is getting better as the exhaust beds in. I just went to the local shops to drop off a video, as I was pulling out, just above idle, you can really hear the turbo whine/whistle from the exhaust. So much so that several of the local hoons stopped talking to each other, and I heard one comment "Is that thing a turbo? Nah, couldn't be. Shit, it is turbod! What the heck is it?"

As I got out onto the main road, I gave it a little in 2nd, came on boost, had a little wheel spin, then had a chuckle as all of the boys picked their jaws up off the ground.

Just wait until they find out it's an oil burner!  

[Dazzler]

Stop it.. yur makin' me jealous (You mustn't have a she who must be obeyed...)

Would have luved to see those hoons faces...

[Lakes]

Do you think the little Diesel will last long reving it?
i know most diesel's don't need the Turbo worked on as they are only low rev, were a small 4 cylinder turbo needs the turbo done every 100,000k as the turbine spins at high speeds, thats a lot of work as i have personally watch those turbine's being balanced pain in the butt job!
personally i think that is a good mod, if it gained more low end TQ, but if it lost low end TQ it would not be as good.
did it gain low end TQ?
Cheers

[Thumper]

Lakes, a rev every now and then to 'blow out the cobwebs'  is ok, once an engine and gearbox is up to operating temp.

As I said, that is the first time I revved it that high. It took me by surprise how easily the revs climbed and how easy it wanted to stay at the top end. I normally never go above 2,000rpm. (Hence I've gotten the best economy thus far for a club member here)

As for low end torque, listen to the second video, that is a roll on, 2nd gear, 1,600rpm onwards. The pick up down low is better than before. The CRDi feels like a large petrol engine (One that is at least twice the size)

I wish to keep my i30 for a long time!
