    Fair enough just consider the interior is quite isolation environment. Much more so then an Elige. Drone is never good but the car definitely needs some more volume on the outside. Remember what the i4 community cry far is something that can be loud and aggressive as the v6. My elise exhaust met...

    JB4 Thread for Lotus Emira AMG i4 (M139 Engine) – Tuning, Setup, Results & Support

    It really depends on how long you want to wait. I don't have a lift either I simply went to the local automotive supply store and got ramps and I did the installation the way CSI suggested. Which is to remove the bolts to the AC compressor slide over the belt to get access to that intercooler...

    Wow pretty good, very accurate on the map3 whp I checked with Burgers number. It was within 1whp difference. Shame there is no way to unluck the 40hp they took on you guys outside the US

    Broken Axle? GI in built axles and how common this issue actually is.

    Is this a dealer installed package because I never heard of Lotus offering such a thing

    Im seriously scratching my head on this one. People are complaining about the quietness and lack of aggressive sound and you are promoting a "freakishly quite" muffler? I think you guys may have missed the mark. They want this for their turbo car My turbo 4 pot Elise). NOT more sedate! Maybe...

    Yes, it feels like the fastest map. I also like the chemical cooling Ethanol provides. I did not log but I can. I am on Map4 The car started and runs with no issues at all thus far. You wouldn't know anything different. I have the blended 100 octane in there now but will return the E30...

    There is one boost pressure sensor that connects with the intercooler which is a pain in the ass. There are two ways to do it. I did it by dropping the AC pulley and belt and got access that way. I believe the other way is to drop the intercooler. It's not that it is complicated thing to do it's...

    I've used VP octane booster in my turbo Lotus Elise for years without any issue. I would add a full bottle (about $25) to my 10 gallon tank which gave me 100 octane. And I was boosting about 25 PSI. In the Emira I add 1 and 1/2 bottles to a full tank. That brings me just a little over 100...

    It already did 3.2 on a lower map. I don't know if there is much more to be gained 0-60. It's more than horsepower, things like traction limits, track conditions, gearing etc. I think 1/4 mile time tells the story of horsepower. I have a draggy pro. However, they just changed the law in Florida...

    Wow - I might be going to the I4 Darkside

    I came from 20 years in a Saffron yellow Turbo Lotus Elise. When I got into my Hethel yellow Emira i-4 turbo it was clear to me it was time to move on. It is just so much more modern and supercar feeling compared to the old Camry supercharged 6 speed I test drove. Not to mention it is a good...

    Exhaust System Upgrade Options Available for Turbo I4 AMG Engine Yet?

    I really hope your guys are willing to make a few of them. Maybe it will be cheaper and easier if he makes a small batch. Rather one by one. The weight saving on this type of exhaust would be substantial

    Personal Insult? What the heck are you talking about? Asking if you even own a Lotus or not is a question and not a personal Insult. There are many people on car boards who Don't actually own the car but are fans of the car. To ask me if I ever owned a manual car would be fine I would simply...

    I am baffled at how many people have claimed the sports suspension was to firm and twitchy. I find it to be rather compliant and very comfortable. Couldn't timagine shooting for something softer.

    DCT feels like a clutch car. I just won't be balked out of any gears. Deal with a clutch of a thousand pushes a weakened or have to rev match. Urban life isn't fun with a manual. Out of town and open curvy roads makes better sense
