Looking forward to the de-rice video of this series. The doorstop falling off was a good start.

[@anomamos9095]

Tip for mocking up exhaust and other tubing. Grab some pool noodles cheap garden hose and some lengths of stiff wire. Try the pool noodle in where you need to put a pipe to see if it will fit the area and bend to suit etc. Then run a bit of the hose down the noodle and some of the wire in the hose. You should now be able to bend and join the noodles and have them retain the bends so you can use them as a template.

[@jrlittle2]

I really enjoy the honest mistakes you show. I know this is a challenge but you're being up front on the whole project!

[@marcmigneault8364]

Love the track car build. The cats would probably have cut more noise than these « mufflers ». Keep up the good work!

[@timgosling6189]

You being a professional an' all, I was hoping for something more special in putting out the fire.

[@reTool462]

If you're going standalone, ditch the maf and go map/tps for load sites👍

[@francisouellette5938]

Jeff, you've gotten so good at this that you now think about how practical it will be to take things off. Brilliant. Cheers mate.

[@deanw9705]

Make your own intake from scratch, using a weld-on MAF flange.When it comes time to go to an aftermarket ECU, just leave the MAF in place to blank the hole.

[@andrekardol]

Luckily you're a firefighter 😉. I managed to set myself on fire yesterday cutting a spring of 😬. No harm done luckily.

[@nickmassey9104]

Great lil update

[@Brendan.Wheatley]

Great progress and keep up the great content!

[@johnmckenzie427]

You could design a cold air intake system, where the filter is located in a more remote and convenient position? Great job, Jeff. I really enjoy your work. Dave

[@VolV8]

The Roxster is gonna be beltin'-out Iron Maiden at 120dB with that exhaust 🤘🔥 I'd love to see a hardtop in place ($$$). Thanks again for the upload 😻

[@robwhite240z]

If its too loud, a quick fix is to make some J pipes. and if its a track only car, make that air filter get or in the cold air = free HP.

[@benstrait333]

...bolting everything up and connecting it in for the last time... Famous last words, lol

[@benstrait333]

For the record, I went and wrote that comment as soon as he said that line, lol

[@mako757]

awesome! nice work keep on keeping on!

[@leesmith6750]

I wish I had the garage space you have Jeff. Great projects. Keep them coming. Be interesting to see the porker on the track. Will sound awesome with the V8.

[@stuartd9741]

It's a fire engine! 🚒 Yeah, 2ft straight pipe, that's exhaust is probably going to be pretty loud Jeff.🙉 Nevertheless it doesn't matter if it's nasty it's a track car it's going to get hard use. .. I am going to suggest that original Audi ECU is probably still ok, unless you actually see it let the smoke out? As someone mentioned in the last Roxster vid, USB is 5Vdc. Audi ECU 12V - your laptop took the hit but the ECU was powered correctly. Still might be worth getting someone to [check it's working] re-flash the original ECU just so you can get the engine running. Good stuff!👍

[@chrisbird2458]

Brilliant…so was the guitar playing 🇬🇧

[@adrianvringer340]

It’s gunna sound wicked.

[@anthonybolic1428]

Possible option for short mufflers is the Vibrant ultra quiet, run on on my e30 track car keeps it under the DB rating 👍

[@trapjohnson]

Quick and Nasty seems a good description of your intentions for the Roxster really.

[@ianskinner1619]

bit of a Db hack, point the exhaust tips to the ground, most measurements are done above or at hip level and the tarmac, especially hot tarmac will absorb a lot of the output. Do it here in Ontario where I built a lot of catless/open muffler rotorys and it hack takes about 15 Db off the high end of the range.

[@HomeBuiltByJeff]

Good tip.

[@pascaljeske7307]

Wow its in fire but best of Jeff and a next cool Video Love it ❤️👍❤️

[@JamesChurchill3]

Hey Jeff, have you thought about trying out a Speeduino ECU? Brainchild of Josh Stewart, a fellow Aussie.

[@zomie1]

Built in map too

[@AdamDUrso]

@@zomie1 only 4 cylinder really at this point if you want sequential injection. Got to wait for Drop Bear!

[@harryfahrtdenwagenvor5202]

I enjoy 😉👍😘

[@samperras]

Hey J your rushin

[@AlfaElaborazioni]

"It's going to be a pure track car." But it has a heater. Does it need to be streetworthy?

[@couttsy222]

Handy for wet track days and keeping the windscreen demisted :-)

[@Jonathan_Doe_]

@@couttsy222 Also good for trying to pull a little bit more heat out of the coolant system if your engine overheats. Smash the heater on full blast and pray you make it to the pits.

[@couttsy222]

@@Jonathan_Doe_ - so true. I've had to do that myself whilst competing in a rally!

[@leebuckles2364]

If that was you throwing toys out of pram when you fried the laptop What are you like when you get really angry lol Great progress and can't wait to hear it running and impressed how you can switch between projects so easily

[@HomeBuiltByJeff]

My mind is continually jumping from project to project working on the next issue for each ;)

[@leighholman600]

Geoff do you really need the Air Flow meter with the Link ECU? Easier tune without it.

[@deetesmin]

If you're goin to use an aftermarket ecu, why do you need an airflow meter? You just need inlet temp and pressure plus a throttle body.

[@theimprovementsguy8871]

No rubber hangers for the exhausts to move? Wont this create a little issue?

[@kaisaras15r]

Hi Jeff, l noticed at 11:55 that you have kept the first catalytic converters, did you do this on purpose?

[@deetesmin]

Ok so you said that were going to use a map sensor later. Why wait?

[@marioslybo108]

Mate you know that you need the ignition key the speedometer and the factory ecu of the audi to start the car because the immobilazer. or you have put another aftermarket ecu to be able to start the engine.

[@malcolmbennett3907]

He's blown the stock ECU. Now using a "LINK" aftermarket ECU

[@HomeBuiltByJeff]

You don't need the key or the speedo, you can just flash the factory ECU, but as I said in the video I am going with a full Link ECU set up.

[@alienpoker]

That cut down exhaust isn’t going to cut it. I bet you decide to replace it the first time you start the engine. I predict it sounds like zoomies in a V8.

[@mrcasperjensen]

Surely you’ll ditch the Airflowmeter as you’re going aftermarket ecu

[@frankalarcon635]

Just as an observation, when you're re-fitting your engine instead of lowering and raising the hoist to try to fit the engine, potentially damaging something, (could you have the hoist set lower and use the lift trolley to raise the engine into place?? Or am I missing something?

[@HomeBuiltByJeff]

Same same. The issue is it is easier to see when the car is higher.

[@KipppopotamusJR]

Secretly wanting to add even more rice stuff... Technically a sleeper?

[@danielprivate7442]

If you don't know the decibel cap at the track...I'm sure the track marshal will let you know when he hears this thing. lol

[@MyBlueZed]

The track has a meter at the end of the main straight which takes a photo when triggered. The marshal pays you a visit in the pits with your warning or expulsion after the session.

[@baddage]

And builders fatigue sets in. Break time.

[@alessiocarlevaro6934]

Won't the exhaust rattle inside the tip of the other one?

[@HomeBuiltByJeff]

If it does it will be drowned out by the screaming exhaust :D

[@robfaith6029]

Jeff mate if it's only going to be a track only car why would need a heater ??

[@stevejones9788]

Demisting the windscreen is pretty important 🙂

[@fcknhellmate]

Probably it is not possible to swap manifold 180 degrees like in the ferrari?

[@HomeBuiltByJeff]

There is even less room the other way around.

[@rodn5616]

Have you ever kept track of your hours Jeff?

[@HomeBuiltByJeff]

I don't want to know ;)

[@timwhalan6417]

👍🏻🍺👏

[@ozbusa]

I would've thought a heater wasn't required for a track car?

[@EliteRock]

you've got a point, but it does act as auxiliary cooling.

[@HomeBuiltByJeff]

Some events still require a windscreen defroster.

[@dubaitacker6347]

hot dogs worked on my boxster

[@mack1541]

Jeff could you not just use the boxster silencer or is that a total no go

[@HomeBuiltByJeff]

They were too small. It would have been a restriction.

[@herme99]

Where's a fireman when you need one.....

[@gregsnell965]

"Why am I putting cats on it?". So you don't get kicked in the balls by Captain De-Cat? (I'm kidding. I know it's a track car)

[@Escygt]

You're wasting your time with that exhaust. Need proper silencers. A mate has a V8 Boxster and it's really loud with silencers 3 times the size.

[@brianhutchinson5299]

Hi Jeff I just wanted to bring this to your attention. Now you don't have to pay any attention to me whatsoever. I do think you are suffering from a lot of stress

[@rogergags]

OMG, one thing after another......maybe just stick to the Alfarrari.....!!!!
