Rotus Project Build

OK cheers Kev,

Ill do some "googling" on NA systems too

YOUR lights........ "turned out nice mother"

Looking at the pictures, I would  Zircotec as much as you can afford at least the system from the engine block to under the car, especially where it goes through the body. BTW beautiful pipe work 

Not sure if you have done much research on Zircotec  but the coating is not to be confused with any other form of coatings which people often do.

I had my manifold, Turbo and down pipe coated. I am going to get the current Turbo coated like the old one was because even after a race you could almost lay your bare hand onto the housing!

Also have a look at  Zircotec Zircoflex Form Rigid Formable Heat Shield as this kept my feet nice and cool in my footwell  last weekend.
I actually blistered my foot at Brands through my race boot and wish I would have used it sooner.

Bugger, I forgot to say, I like that pipe work too

I've only experience with turbo motors, 3 inch systems and quite a bit of overlap so strong exhaust pulses Jamie but on those the resonator seems to work best around 24inch from the downpipe. My default system now tends to be a flexi section right behind the downpipe into the resonator the pics of a larger 1 into 2 resonator system but you'll get the idea.

What size down pipe? I have to figure out that resonator thing too. What DB your car has?

Btw, that turbo looks big

Yeah, that's the plan. Mainly on the headers because they come upwards on my application, right next to the chassis so that will have the powdercoat melted off it, and the solenoids on the intake manifold, and the OMP stuff is really close, and the steering column, and, and ,and.

The decat pipe was either ceramic coating, or that yellow rigid stuff you shown, formed in a U channel and bolted to the bulkhead with the open end facing upwards and it will protect the belhousing and intake from the exhaust. Then some vents in the bonnet.

There are lots of options really. I could even combine heat protection i.e. exhaust wrap + heat shield. I know on the RE Amemiya 20b Lotus Europa he lined the bay with gold coated panels as that's a good reflector of heat.

Im a long way from all that to be fair, once the shell is painted I will be going belt n braces on the heat side. Im always thinking 3 or 4 steps ahead on all the stuff I do, (easy when youre an over thinker like me lol, screws up my personality tho) .... if I make this what else does it affect? yadda yadda...... where I fall down is my lack of knowledge on rotarys.... that's where you all come in 

Thanks for the nod on the pipes, thankfully I don't need to redo the engine bay, just the stuff under the floor and near the diff. I really need to find out about the resonator and relocate that. Im buying some more pipe and bends today. I need to hack some more GRP floor away, but its under the fuel tank.... lol don't panic.

Oh and because of the diffuser, the tailpipe will be side exit, driver side so I can see any flames in the mirror lol.

Chill Kaveri ! its all good 

[Jamie R]

Been carving up the floor and exhaust atmo.

Ill show the old system first, its a bit pants........

......in my infinite wisdom I thought Id flatten the pipe into an oval and pass it under the chassis....

well ive gone off that idea.

[Jamie R]

So ive carved all that up, fired the TIG welder and did it properly.....

[Jamie R]

Missed one

[re japi]

Looks awesome. But your feets are going to burn

Lol mine won't, I'll be on the drivers side

Can anybody recommend a good brand of silencer that's not over the dB limit for trackdays and on the road etc?

My local stainless exhaust place makes them, but I don't think they are repackable.

[Jamie R]

Thats another evening sacrificed to the exhaust Gods.

Sigh

1 cut, 4 burns

Things you do to miss a differential

I feel a boat load of welding coming on

[re japi]

DAMN! 

Flight here to build my exhaust asap!
