Evora GT410 Upgrade -> More trackday focus

[geartox]

Even if the main improvement to do is on the driver,  I have decided to make some modifications with KT :

- Öhlins TTX
- Toelink upgrade
- Trackday chassis setup
- KoBra 4-4 Brake Upgrade
- EV4-475 Power Upgrade

Everything will be done at Mendig directly, beginning of April 2024. 

I bought a second set of wheels and I plan to test some different tyres.

I will share here with the community some pictures, feedback and feelings about the modifications.

In 2025, I also plan to go further with the modifications and go for 500HP or 600HP power upgrade with forged internals and DCT. For that I would like to compare Komo-tec solution with Jubu solution. I plan also to visit Jubu HQ this year to see what they have to propose. This is of course a most risky and complex step. We will speak about that later. 

 

I have made some videos to compare my old Exige 440 IPS with my stock Evora GT410 IPS , very excited to see what it will be with this upgraded Evora :

Your car is going to be a Pork-slaying monster once that lot is fitted!

The car weight is 1364kg with fluids

My first feedback on road :

- the car is more stable
- the front end is sharper, the car seems lighter
- less understeer
- I feel the increased torque 
- sound is more "mettalic", more louder at low revs
- the brake seems awesome, but I have to drive more before to use the full brake power

Everything is fine and the car seems clearly improved.

Of course the real judgment will be done after trackday.

Maybe a small video on the autobahn is coming

That's impressive dyno run for an IPS car, as they tend to not play as nicely on the Dyno as the manuals. 

 

Have you noticed any issues with the IPS and the extra power? Did you upgrade the IPS with the BoE Shift Tek kit?

I have one of Jokerz 2.9" supercharger pulleys, Ti exhaust, and headers and airbox to go on my 400 IPS soon. I'm slightly nervous of the gearbox so any reassurance you can offer would be good!

Really nice build. I must say that I envy you for starting your project on a GT410 with everything looking brand new and being developed a bit further before start, than my 2011 Evora S.

So, what are your impressions after this season?

@geartox, have you added a baffled sump, or do you not see the need?

Fantastic build. Car looks super.
