I just had a question about the headers. Could they be installed without tuning? I wanna do the power package but at this time I can't have any real down time to send the ECU in for the reflash. I was thinking install the headers next time I get the car on a lift then when I can, do the reflash and install the intake together. I have a 2011na 6sp with sport exhaust. Was thinking of the headers with cat.
Also, is it possible to pick up a second ECU and have that flashed or you can't swap ECUs like that with these cars?
Right now I'm having cold start issues so I have to see what that is first so I don't open up a can of worms.
Yes, the headers do a very nice job without tuning. You can just bolt them on and you'll have power. The tuning just makes them better. The biggest change is from the headers themselves. The cat with our headers costs literally no HP in our testing.
for the 2011 NA Evora, we can do an email tune. You just need to buy the cable at check out and send me an email to accompany the order. I prefer to have the ECU for now, but if it's really pressing, we can do the email thing with software on the 2011.
Your missing some of the points about CA smog. The CAI will immediately fail you as it has no CARB/EO#. Any cat removal will immediately fail you as well. We get semi-lucky with the cats as they are not likely to remove the plates to inspect. However, if they see headers they are more likely to inspect and fail you.
For CA cars it's better to have a drop in filter, muffler and tune. It may not give us as much power, but it's a sure thing at smog. Potentially, we could get away with a secondary cat delete as they aren't likely to look. Headers generally alter the heat shields and make themselves visible. Smog stations are getting really good at looking for mods these days.
What's the wiggle room like for putting such a package together? Estimates on hp/tq would also be nice.
I'm not missing it, I just "suspect" that there are many many CA cars running around with aftermarket tunes and parts that go through smog just fine.
The headers are essentially impossible to see on the evora. the cat is present and passes sniffer from what I'm told.
You don't have to run the CAI, but it hides under the engine cover, so why not? or jsut swap it back and forth and modify the stock airbox so that it's easy to remove/swap for the visual.
From an environmental standpoint, the emissions output at cruise and idle, which is where they care is not modified, so you can sleep well at night
I cannot perfectly comment on how every little change will impact the output. What I can say is that when the package is paired together it works very well. When you deviate from that path, output will drop. It's hard to say how much. It won't go back to stock though. that's for sure. As much as the brain would like it to work this way, each component doesn't just add X, Y, or Z power independent of another factor. It's a big airpump and works as a system.
To that end, I'd imagine the cams will fly though an inspection too. I don't advocate or endorse cheating your state smog inspection. All parts are off-road use only. That said, I'd guess they would pass....
I'd gather that there will -never- be CARB aftermarket parts for the current generation of Lotus cars. Never is a long time, but it is my guess...
