I haven't looked at the specs of the Jubu 440 tune, but I'd be very surprised if it's able to deliver that much more torque with only a 40 hp increase in power. 500 Nm translates to about 368 ft lbs of torque which I believe is the limit for the transmission more than the engine.. My car stock showed only 303 ft lbs, and the Eventuri took it up to 318 which is still well under the limit of 368. I don't think the 3rd cat delete will have any effect on torque, just sound mostly. I'll have to look up Jubu's tune and see what they're claiming.Would be interested for your thoughts on the additive effects of these mods on torque. The Jubu 440 ECU kit has been optimised to max out at 500Nm which I gather is the limit for the standard Toyota V6 engine before strengthened parts such as forged pistons and conrods are needed. Would a Jubu 440 ECU plus a 3rd cat delete and Eventuri intake push the torque above 500Nm? Or put another way, to avoid expensive engine upgrades (or a blown engine) would the Jubu ECU programming have to be modified to reduce torque to compensate for any increase provided by the other modifications?
I wonder if that comment about the factory boost pressure applies to the Emira, as opposed to the Evoras which were 416 to 430 hp?Jubu actually limits torque to 500nm on all the packages that don’t include a built engine. Both the 440 and 460 tunes have 500nm.

The 460 package actually comes with a smaller pulley to power boost pressure

I think the manual gearbox Lotus uses in the Emira is intended for use in combination with a diesel engine so can probably take more torque as a consequence. Maybe the auto box is not as strong. I’m interested in the Jubu 440 ECU as I suspect an extra 100Nm will make a noticeable difference when accelerating from low revs (not to mention the extra 40hp) and the rev limit can be raised to 7,200 rpm. There is also an auto blip option for rev matching on downshifts. But it would seem the Jubu 440 ECU can’t be used in combination with other performance improvements without strengthening the engine or managing torque so it does not exceed 500Nm.I haven't looked at the specs of the Jubu 440 tune, but I'd be very surprised if it's able to deliver that much more torque with only a 40 hp increase in power. 500 Nm translates to about 368 ft lbs of torque which I believe is the limit for the transmission more than the engine..

Okay, after having just looked at their website, they're claiming quite a dramatic increase in torque. An additional 100 Nm is 73 ft lbs. They're saying that it's the engine that has the limit, but I was under the impression it's the manual trans. Maybe they're thinking of the auto trans? If you're going to get their tune, I would definitely recommend telling them about the Eventuri as that would push things over the limit they claim the stock engine has. Obviously this would void your warranty, and undoubtedly blow your emissions compliance out the window as well. There's also a possibility your insurance company might cancel your policy. It certainly has interesting numbers though.
Was it hard to do the doors and was the bulkhead panel fitted in the engine bay or cabin?I have the same, all 3, and always have the valves open - unless arriving home late at night, then I shut the valve and its significantly quiet and won't wake up the neighborhood.
All have installed Skinz sound deadening to both doors and the whole of the rear compartment / engine bulkhead, which helps massively with holding a conversation with the passenger, phone calls, no more stone flicking noise, listening to music on the motorways etc, if this helps you?
Not hard, just time consuming to cut everything to shape.Was it hard to do the doors and was the bulkhead panel fitted in the engine bay or cabin?
I’m curious what your dealer will say about the intake modifications. Seems to be a crap shoot one to the next with some flat out voiding the power train warranty and noting the vehicle file as such even if the OEM is ever put back on.My goal is to improve performance by reducing weight and improving drivetrain efficiency, which won't have any negative effects on the engine or trans.
The closest dealer for me is 360 miles away in south Salt Lake City, Utah. Since I'm going to be doing my own fluid changes, the only reason why I'd need to go to the dealer would be if it's something I can't do myself. I'm almost at 1,200 miles, and the car has been fantastic; no problems. I may schedule one trip just for any software updates, and for the water shield for the front resistor, but none of that has anything to do with a cold-air intake. I haven't deleted the 3rd cat nor am I going to.I’m curious what your dealer will say about the intake modifications.

Same for cat delete pipe. People can say Magnuson-Moss all day but it’s not I fight I’d like to have. I hope your dealer is one that appreciates the small modifications that don’t harm the vehicle.
I don't know how to run a dyno, so I just trusted the operator to know what he was doing. It was the same guy, same dyno, so I figured the results would be representative of the actual gains the Eventuri provided. We're at an altitude a little over 2,700 ft.
I can tell you there is a definite difference. I noticed it right away just from starting the car. The engine stability is noticeable. No vibration in the shift lever. The car now feels more lively right from the start, instead of waiting until I get up above 3k rpms before it really starts to feel like it's pulling. The feel is the same now all the way up the rpm range. It feels exactly like the performance curves on the dyno chart show.
We have ridiculously hot weather right now, so I'm not out driving. We've had 100+ for the last few days, and that's projected to continue for another 8 days. It should feel stronger in even cooler weather.
I'll probably do the engine and gear oil change next Tuesday (gotta do everything thing in the morning before it heats up outside). My Aerie wheels are supposed to arrive on Monday, so I'll put the car up in the air to change those out, and do everything else at the same time the wheels are all off. This includes removing the wheel well liners and putting sound dampening material on them.
The reduction in unsprung rotating
Can we finally put to bed:weight the wheels provide, should make a nice improvement.
Evora is a great car, but only sold 6,100 units over an 11 year period. The Emira has sold nearly that many units in ~2 years.Can we finally put to bed:
Emira is a lesser car than the Evora
Pretty sure he is referencing performance and raw race car feeling. The Emira is softer and less performance based GT car. That is why they sold more not because it performs better.Evora is a great car, but only sold 6,100 units over an 11 year period. The Emira has sold nearly that many units in ~2 years.
Based on that alone, I’m not sure most people would agree with your statement.
