BOE Headers installed on my Sport 410
Have any before and after sound videos? Notice any difference in drivability or power?

I REALLY want to do this one my 400 :grin2:

Also, thank you for your pictures of the headers where they bolt up, that answers all of my questions on the install, haha!

I had headers on my 2012 S for years, 1st Komo-tec headers and tune, then BOE CAI (prototype) and BOE custom editing of Komo-tec canned tune, finally BOE headers and BOE Fastracks tune. Each step improved drivability and power, although I would say from gut that my OEM 410 drivability felt as good as final BOE tune and power was similar but different, BOE '12 more linear, 400 OEM less power at low RPM's and slightly higher peak (i.e. less linear).. power feeling compared track to track on Barber Motorsport.

Today I have driven 250 miles on city, interstate and country roads, no track duty. drivability same as OEM, power difference?? adequate so far. Note I do not yet have a BOE tune which could buy 15 Hp or so.

Curves (not from current car, but with BOE headers)

July 2016 MY 2012 (jpg) - same Dyno, but different weather July vs January
Upper : BOE long tube header, Larini muffler, BOE CAI, BOE Fastworks tune
Lower: same as Jan 2013 (upper) 2013 KT Headers ... CAI + Larini muffler


Jan 2013 MY 2012 (pdf)
Upper: Lower + BOE CAI
Lower: Komo-Tec short tube header, BOE modified komo-tec EV390 tune

Changed all interior lights and Lic Plate to LED (anyone have any other suggestions?) I think the look great ... OOOH !!! Take out the 3A fuse before changing footwell lights .... shee's happy there was a spare :). Then Cruised my 2011 to 34,000 miles after visiting my parents.

Nice! Looks like Lehigh Valley Cars and Coffee, right?
yup... Going again in June if you want to form a Lotus squad.
Oh yeah! Already got the day off from work and have my fingers thoroughly crossed for good weather on that day. Yeah, let’s form a Lotus group for it.

A while back I bought a group 47 Antigravity battery, that wouldn't fit on the factory battery tray, the group 47 battery is taller than the 91 the car came with, so the OE bracket wouldn't work. I figured a strap solution would do the trick, but I ended up adding too much lightness, and the battery would slide to the right on left corners (it held tight in right corners and wouldn't slide left for some reason). To resolve the lateral sliding, I put in NASA cardboard to take up that space. (I wasn't terribly worried about heat/fire, since the auto ignition temperature of the cardboard is 250C and the thermal runaway temperature of the battery is 150C, meaning by the time the cardboard ignites the battery is already burning the car to the ground.) Well, the NASA cardboard and BDSM straps didn't give me the warm and fuzzies, so I made a new battery bracket. The bracket I made, isn't pretty, but it is functional. Since the new battery is 1/8th the weight of the AGM OE, I can get away with it being smaller and lighter.

Simplify then add lightness > beautify then add lightness.

Awesome. How much do those batteries run anyway?

Lol. I saw that too. I ALWAYS ran my Evora in Sport Mode and occasionally used cruise so I get it.

Got a set of Michelin PS4S and an alignment (MY11 Evora S). This setup really beats the hell out of the 7 years old Corsas... No regrets for going away from the hard to find Corsas.
