Popular Post dbo 9 Posted October 18, 2018 Popular Post Report Share Posted October 18, 2018 16 hours ago, Kristof Thys said: The ECU won't know. There is nothing to worry about. Just to be complete, the ECU electronically controls a valve in the engine bay to allow the vacuum to flow from the engine to the exhaust actuator or not. If the vacuum is allowed, it will pull the butterfly closed on the straight through pipe entering the silencer, thus changing to 'quiet mode'. The butterfly is sprung in the pipe to be open by default, so removing the capability for the vacuum to reach the actuator means the exhaust remains in big bore/straight through mode regardless of what the ECU does with the valve. As for ECU knowing, there is no sensor on the vacuum portion of this control or actuator, and from a logical pov, why would it care as the (engineering) problem is if the exhaust is kept in quiet mode while under load, not opened. Id expect that the ECU can monitor the controls it sends to the electronic valve (in the engine bay) to ensure its functional. 3 Quote Link to post Share on other sites
Tex 215 Posted October 18, 2018 Author Report Share Posted October 18, 2018 I am aware that Komotec do a 500 bhp upgrade at a price in region of €25,000 but this i think this is more suited cost wise to V6s and 350s upgrades What would be possible for the 430 or even the 410 as while there is ample bhp for road , a little extra on track never hurt . Haven’t seen any power upgrades for these models yet but would like to know what is available Quote Link to post Share on other sites
Bravo73 1,255 Posted October 18, 2018 Report Share Posted October 18, 2018 There is an EX460 kit offered by KT/H111 for the 4X0 series engines: http://www.hangar111.com/shop/komo-tec-lotus-tuning/670-komo-tec-evora-400-phase-1-ev4-460.html Quote Link to post Share on other sites

I thought the KT 500 went above the recommended torque levels Yes and there I guess lies the biggest problem as the EX500 appears to have a sequential gearbox option presumably a lot stronger than stock. The stock purchase from KT has uprated forged pistons and con-rods but no gearbox mods that I can see and may well be above the standard gearboxes torque tolerance.

Basically, yes. EX390 would give you around 400-410, then EX430 and EX460 are same as 350-based cars. Would recommend the chargecooler solution of you can afford it, given your ambient temperatures.

Would be good to see just how quick a 430 can be and perhaps silence the EX460 v Cup 430 debate Yes we have a couple of options for this, the standard ECU with a KT map, or fully featured aftermarket ECU with bespoke mapping. Once I am back from race weekend, I will chase up on progress with the 4x0 ECUs, but feel free to give me a prod! Dave 3 Quote Link to post Share on other sites

Andy Norman 75 Posted October 21, 2018 Report Share Posted October 21, 2018 Just went to take the roof off. I don’t have the tool to get the 4 remaining roof bolts out. It’s a star design like the front window valance but with a small circular protrusion cylinder in the middle. Annoying!! Anyone know where or what this attachment is called so I can buy it?

I have seen another post which places a (fish tank) 1 way lever valve in this line which gives the option of manually enabling/disabling if thats more appropriate for you. This tube?

Anyone know where or what this attachment is called so I can buy it? so bizarre! there was another thread where we were discussing how Lotus stopped using those bolts and started using regular torx bolts. I guess they must have run out of these bolts for awhile and started using normal ones until they got new stock... Quote Link to post Share on other sites
