    Is leasing an Emira a good idea?

    I've leased several cars, typically it ends up costing more, but cost wasn't a primary factor, more so piece of mind (didn't care about them). Really depends on the terms. With the cost rising on new Emira's the older ones will probably hold there value better. What are the terms? does the...

    https://www.lotuscars.com/en-US/emira As usually lots of inconstancies for US market, 0-62 mph instead of 0-60. UK site has 0-62 for the Turbo at 3.8s. US site is 4.0s. So odd. No pricing yet. Only new option I really would like is the [Blind Spot monitoring] and [Lane assist]. You can...

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

    Great pictures. Keep those coming, not many pictures out there of chassis without the skin. Any idea if the plastic vents in the second picture release air into the bumper skin cavity and release air into the rear black ports? I noticed there are very small vents at the top of the ports.

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

    [Baseline (91 Octane): 387.5 hp / 311.5 lb-ft] With a parasitically loss multiplier of 12.5 % for a rear engine DCT, that suggest stock config is over 430 HP, which would be inline with C&D 0-60 figures of 3.4s JB4 map 2 comes in around 500HP. 60 to 70 HP is a good amount of HP to pickup. Will...

    What car is more beautiful than an Emira?

    Yes It is manual. Test drove the Auto, while it paired well with the turbos it really wasn't very impressive. Auto tech in the 90's wasn't that great.....

    What car is more beautiful than an Emira?

    I still have my RX7; bought new out of college. Tacked for bit in my 20's. Didn't drive it much afterwards. Only has 5,900 miles now. Still smells like it's off the showroom floor inside. A similar RX7 in the county next to me sold for $148k a year or so ago. Had similar ultra low miles....crazy

    [a 0.6 sec decrease in the quarter mile time (map 4). I think that's pretty substantial.] Yes, think your 1/4 mile improvements are the strongest so far and would likely represent a strong 60 HP pickup. What is map-4 again is that E30 fuel? I recall you posting 0-60 3.2 sec - right? What...

    Wow, your car pulled ~ 1 G in initial acceleration, impressive. Shaved .2 sec on 1/4 mile and picked up 2 mph of the C&D results. C&D Probably ran this test on cooler less humid day (December in CA). On a cooler day you'll put down even better figures. Wonder what the intake temps are...

    Doing some research on the latest AMG M139 engine. Looks like the M139 can operate at higher boost. Assuming proper cooling. Latest version operates at 40 psi. Emira version is already at 9 to 1 CR. Factory power output is rated at 469 HP, this engine might also have a very larger...

    Very true, last time I increased boost significantly on one of my cars; I had to up the intercooler (4 times larger, with a larger intake air duct). Yes, people should be careful. I do wonder - with the piggyback essentially overriding the boost value (both cars) sent back to the ecu. Will...

    High level your system is raising boost levels about 4 psi off stock config. thanks Interesting that Mercedes indicates the M139 turbo produces [Peak boost is just under 30.5 psi for the S engine trim and just over 27.5 for the base engine.] Of coarse no gauges on the cars to confirm.
