NitroDann's Long Awaited Garage Thread

For you Dave, I'll let you pay it off in installments by mowing my yard

Airfares might be cost prohibitive hope your lawnmower is turbo'd.

[NitroDann]

Look Dave, do you want an exhaust or not.


Yes it has a gt35r. It's pretty laggy and comes on like a light switch of course by that point you have run out of rpm, but being an Se owner you would be used to that.

I'm gonna be slow no matter how much power I have, i'd like to do it once and do it properly but in reality i'll aim to do it in 3 stages.

- Simple mods to my SE and get my head around an ECU, it really needs an intake!
- Manifold/Turbo (BW perhaps)/Dump/Exhaust on stock motor
- Built motor

Can't really spend any money on the SE until I sell the 2 cars I promised to sell when I bought it and can't really spend money on anything until my wife finds another job and my contract is due to finish at the end of June.

Sorry didn't wanna hijack your build thread.

[NitroDann]

That's cool it's a discussion forum.

Sounds like you have the exact right idea.

One of our younger members here has been on the phone to me about running an Se n/a on their p:s for 6 months while we sort out s good T28 setup for it.

Here we go.

Just needs a flex, a brace and a cat.

Needs paint but its done.


Here is the last hanger guide.


Finished rear section.


Again.



Ill let the pictures say the rest, still needs a cat and flex and a gearbox brace on the DP.

Heres a really good question I had via PM.

It look solid Dann..

How much louder compared to stock? Do you plan to measure the DB loudness so I can be sure it is under legal limit?


cheers

So, firstly thanks for asking, very very good question (bit of a light bulb moment for me honestly).

Because I dabble in bits and pieces that are 99% of the time custom made for a person, we can always work together to make sure that I understand EXACTLY what people want, I think this is really key, and probably a big part of why just about everyone is really really happy with what I build them.

However its all new to me, that is building jigs and trying to be able to supply some off the shelf type bits at great prices and with the same build quality as before.
So I have designed a system for a gentleman which you can see in the above pics and decided its a great setup for 90% of SE owners, because it allows a HUGE upgrade over stock, but because all of the flex and wideband etc is contained in the midpipe they can keep it and simply change dump pipe when its time to go for a T28/3071/EFR series turbo, but also comes in at a good price, will make fantastic gains on the stock setup and will be plenty quiet enough for daily duties.

Being a pretty serious bit of kit for a 1.8L it will support just about any power levels anyone would ever want to upgrade to in the future (ie 400hp+ easily).
It seemed like the right system to build a jig from.

But now, I have the question about absolute 100% legality. Its already stock configuration, OEM quality magnaflow high flow cat and tucked well away, but will it pass a sound check 100%, every time..

Thats a question I really cannot answer...

I know that it will -definately- be quiet enough for the VAST majority of enthusiasts, I know it will pass the girlfriend test, but will it clear the sound check with ease... That I do not know.

So the question is out there, I suppose I should extend it to everyone who owns an SE, and everyone who DD's an MX5 who has an aftermarket system, and those thinking about one.

As usual, Im all ears, and Im looking for people to criticize in every way that occurs to them, with the main question being, does a system for a road car have to pass the girlfriend/wife/mother test only, or does it need to be 100% volume test legal?

Thanks to everyone who read all that, and in advance to the repliers

My 2c
For me it would need to pass the 95db i think it is for Lakeside and QR limits.
But more importantly the drone test.
I have dríven/ridden in an SE with the 3" SS Corksport system and it droned like a bitch at cruise, and sounded like a truck at idle.
I wouldnt be able to handle that as a DD

[emily_mx5]

I would agree with the most important aspect being legal issues and it coming under the 90db limit. Second would be no drone and no rasp. Goodluck haha

SPL meters are on eBay for $40-50.

Might be worth the investment.

[gslender]

Interesting point...

One thing for sure is that it would depend on each state and how they test.

As example, I've got a cat delete pipe installed, and at idle it isn't any difference, up to 60% load it is barely much of an increase to the audible noise, but above 60% load it goes crazy loud and roars. So if the test was WOT I'd fail. If it was idle and steady drive by, I'd pass.

There is certaintly no accounting for taste, to be honest I think its a great idea to buy a SPL meter and then at least I can give 100% accurate descriptions of volume

I can't think of the name, but there is a cool little muffler shop down on the corner kind of near the Georgetown shops - I've had plenty of checks done there, they are stand up guys and fairly cheap on tests - The RTA etc accept their tests too, so you know they do them at the correct angles. RPM etc.

I'd go speak to them and learn about the tests for NSW (or even an engineer) then go buy a nice db metre to offer tests or db levels to customers.

You could also look at selling a basic performance system that was louder with a removable/re-installable section for street use.

For the simplicity of an off the shelf though, I'd make it as legal or close to as possible. Anyone chasing outright power can choose a custom system right?
