power upgrades

[Team Lotus 7]

Hello Everyone,

I'm a first time lotus owner, picked up my car 8 months ago from Lotus dealership Taiwan. Car runs perfectly so far, no issue whatsoever, very exciting to drive. having done few mods and track days, i figure its time to look at power upgrades + brakes.

I am debating between charged cooled or non cooled power upgrades. From what i have read, stock internals are reliable at 430hp so non-cooled kits from both komotec and harrop should be worried free. but what about charged cooled kit? at 460~470hp, is forged internal a must? I do around 5 to 7 track days a year. any opinions are appreciated.

 

List of mods so far: harness bar, Schroth 4pt, oil pressure/oil temp. gauge, moroso baffled sump,

lightweight battery, steering arm, Advan Racing wheels, Carbon roof, Carbon service panel,

Autoblip, momo removable steering wheel, 3ways nitron, Komotec Wing, Aim Dash MX2E.

The limit without doing internal changes is about 500HP. The Komotec EX460-kits have proven to be very reliable (if correctly installed).

@TBD do you know how the 475 kits from KomoTec are behaving?  

Welcome @Team Lotus, your Lotus looks superb (love the wheels) and you've made some nice mods already! :)

My recommendation:

Chargecooled EX460 Kit from KomoTec and Quafe LSD to get the power on the street - this setup is perfect for me, I can't think for anything better!

I would not do any powerupgrade without adding a chargecooler.

If the EX460 Kit for what reason ever is not an option consider to apply the close ratio final drive from KomoTec instaed.

I was hoping for the KT475, close ratio final drive and Ohlins suspension. I think at that point my Evora Sport410 would be the best it could be! :)

No?

If you want a big power step such as over 420bhp etc then id suggest charge cooled if doing a decent number of track days. Komotec for sure being my recommendation as its a complete solution vs Harrop which still includes the choking cats in the manifolds.

You can go to the Komotec EX490 kit for the 350 or 380’s and this seems to be the limit without any internal upgrade but gearbox oil cooler is a definite. For V6’s 460 bhp

Peculiarly Komotec have not fully cracked the 410/430 ECU, hence only 475bhp

What is an auto blip? 

[C8RKH 5,508 2 Vehicles]

It's a software/hardware addon that works off the ECU to automatically "blip" the throttle on downshifts for rev matching etc. For talentless people like me that cannot heel and toe properly :)

No. At least one owner on here has had it fitted.  Komotec did offer it as an upgrade, not sure if they still do.

Yes after some research I have also come across this...

it’s not a mod that’s popular / or I haven’t heard much about it. I can heel and toe, but if there was a reliable mod that improved that I would look in to it. 

[Team Lotus 7]

thanks for all the replies. @TBDGood to know internals are good for EX460 kit. I agree Komotec offers a more complete kit with full exhaust but the track I go has 106db noise limit; OEM exhaust rev to 4K just pass the limit by a few db. what I do now is rev to 3.6k and hope the guy looking at my dash would give me a break Lol. (3.6k at 98db)

LSD would be nice but requires engine out, If do that, i'll be thinking about forged internal, uprated clutch etc. and most likely be out of this year's budget but definitely on my list later on.

Autoblip and bluetooth earphones are consider luxuries on car like this. I could heel toe just fine but about 2 out of 10 times would not be perfectly smooth; with autoblip it feels almost like PDK downshift, quite pleased with it, plus can be turn off with a button. one thing to note if anyone wants to get one, connection would be better if solder instead of quick splice to car's signal lines.

What brand is your autoblip?

[alias23 1,490]

@Team Lotus have you considered one of the quiet track exhausts? In terms of the LSD it doesn't have to be an engine out... there's a way to make it work with the engine in situ and without removing rear clam. However its still a pretty meaty job.

[Team Lotus 7]

@GazzyFizzle bought and installed at Taiwan lotus dealership. https://www.auto-blip.com/

@alias23 not really, cuz prefer to be louder if I change. Any pictures on lsd installation without engine out? Curious how many second off my laptime with lsd.

 

[alias23 1,490]

Sorry @Team Lotus I don't have any pics but it is possible.

I'm curious why KomoTec dropped it.
