The E is maximum ethanol content as is up to 10% in E10 the U.S. standard in pump gas regardless of regular/mid or premium grades. The important thing here is to never exceed E10 and less is best for a given octane. Ethanol content does not correlate to a octane level, other than that Ethanol...

20 mph is all tire rolling resistance not aero drag.

I've had the GRP Ti rear muffler on for over 1000 miles, while I cant compare it to a standard exhaust Emira as the dealer installed it along with Miltek valve controller, I can compare it to an older Evora fitted with header, mid cat and factory Ti exhaust. The Emira has more drone, while the...

$2700 for installation is rape, however if the exhaust swap included a Tip change then the hours do build up as the rear bumper must be removed.

Not a constructive comment, but I laughed when I saw a post saying the the ECU was a 15 minute swap out.

Months later, there is no connection between the EPA and CARB review boards, each in the independent bureaucracies with their own workload and schedule. while this may have some truth, the statement that they will build MY2024 cars in 2025 is impossible. This is not permitted by any major...

A few dozen i4's arrived in US near end of August along with the first V6 automatics.

Manufactures destination change is a standard add on to MSRP by manufacturers. While they (automobile manufacturers) set their own fa level. It is a standard charge to cover car shipping and prep to the dealers door.

Same OE ECU hardware, but the code is definitely different between markets as dictated by regulations. At leases 3 variations, EU & ROW (maybe UK is different now), China and North America (US, Canada, Mexico & Caribbean Islands)

Steep, but very well designed and easy install.

While Jubu makes great stuff I think it is far to premature to suspect cooling problems on the Emira, at least on the V6 configurations. We run these cars on tracks in Texas in 100-110 ambient are temps and typically 140 (60C) air temps above the track pavement. The only coolant thing Ive...

It is not the muffler that puts heat into the engine bay, but rather the exhaust manifolds with intergral Cats.

Only 1684 days since I made first deposit on this Gamma Project

He is being constructive. No gear ratios change between modes. All that changes, and our ears perceptive as a change on exhaust opening, is that both idle speed and redline are increased in sport/ track modes, thus increasing engine exhaust pitch and opening the value a hair.
