Yeah dude, if you're going to make a technical statement online. You'd better have your MOFO scientific calculator and text books on hand !

Nah, I'm sorry about the technical rant, just wanted an excuse to draw a pretty picture

*sigh*

Obviously a generic form that they fill out.

Just so as we are clear, in no way am I advocating that I would prefer a "Rotah" over a "Motah" (lol), but I feel you guys needed to understand that not all rotors are without torque.

Was gonna say...4L displacement and only puts out ~200kw...:sick:

yeah by RTA regulations its classed as a 4Ltr and as we all know jap cars are all restricted to the 206Kw so that doesnt really mean anything either in terms of how good an engine is and what its capable of..........

Ahh yeah just read up on the engine classing on Wiki...makes sense now...:blush:

How many people actually think 206 is a real power figure. Lancer evo states 206 but have been stock dynod at over 300. And my stag did lose against a newish one. Isn't the 206 just a regulation in Japan so they just out that so they can avoid legalities.

Stock dynoed at 300HP but not KW.

My old Evo 8MR was 225kw stock. After mods it was close to 300KW at all 4 wheels. TBE, Profec B II ( 1.65bar), Ecu, Fuel pump ect.

I'd be interested to see the stock dyno of the VQ25det, I recon 206-210 would be pretty darn close.

    • Yeah the ACL and similar formable heat shielding materials are really nice. But most people do not have the patience or talent to do a good job like that. Almost anything is better than nothing though. Even if you didn't form it closely like that and just had a slab of it slipped in between the manifold and somewhere/thing you wanted to protect, you would gain benefit. There has to be a market opportunity for people like Artec to make formed heatshields to suit their cast manifolds. The fact that they are cast means that they are consistently the exact same dimensions and they could add bosses to the castings like you see on stockers to allow heat shields to be firmly attached yet floating away from the manifold itself.
    • I've seen some stuff like this as well, not sure if it's a good idea or anything but it does have more standoff from the piping than the conventional fiberglass wrap:  
    • Jap premium will be 100 RON. You should use 98.
    • The exhaust gases are at their highest temperature as they leave the exhaust port and enter the manifold. They cool as they flow through the manifold because they transfer heat to the manifold and the manifold loses heat to the surrounding environment. Thus, inevitably, the exhaust gases are cooler as they enter the turbo compared to when they entered the exhaust manifold. So, yes, the exhaust manifold can easily get as hot as the turbine housing. Having said that, you will generally see the highest temperatures where the exhaust gases have to slow down or they are concentrated into one area - which is usually the collector on the manifold and in the turbine housing, because the gases slam into the metal at those places, increasing the convective heat transfer coefficient and transferring even more heat to the metal than they might just flowing past elsewhere. Exhaust manifold heat shields are a good idea - certainly for the stock manifold they are there from the factory. People seldom have anything like that on a tubular manifold because they are hard to achieve. Some might wrap a tube manifold with fibreglass tape - but this has a reputation of leading to cracked welds. The best case is generally to put ceramic coating onto the manifold to prevent it getting as hot (internal coating) and radiating/convecting heat into the bay (external coating). All the real heat from a turbo comes from the exhaust side. The gases entering are at ~800-900°C and the steel/iron gets nearly that hot. The compressor side is only going to heat the charge air up to <<200°C (typically not much more than 100°C). So that's nothing, by comparison. The compressor is not a significant source of engine bay heat.
    • Late to the party, specifically joined this forum as I just bought one of these and this thread has been a gold mine of info. If the OP is still around, mind if I ask what gas you been putting in yours? Mine has a Japanese sticker in the cap saying premium but it seems to get way worse mileage on premium (95) than 91. I always thought it was meant to be the other way round🤷 I do think Nissans claimed "6l/100km" is a bit fantastical 😂
