Did lotus rob us on horsepower?

Same. My 4.39 was with a draggy, on a cold day as stated above. I’m not stock thou with the 440 JUBU so will be interesting to see everyone’s best numbers. I will be going with the 460 JUBU probably late spring early summer so will do times on the 440 first then the 460.

I just did two runs with my dragy.

First one was just to try to get a handle on launch technique (I normally never launch aggressively as I hate thrashing my cars in 1st), and to see if I could actually do the run on what was a pretty short stretch of road.

Second run I tried a bit harder.
There was a laughable amount of wheel spin (so I definitely need to work on my technique) and a pretty ordinary 1st to 2nd gear-change, but even so I got 4.88 for the 0-60, or 4.63 with a 1ft rollout.

Bearing in mind that is the first time I’ve ever tried a “proper” launch in any of my cars and I only did two runs I’m happy enough with that.

I have no doubt that with a better driver on a better road the published figures would be achievable, but you’d probably have to thrash the car in a way that I don’t really like doing.

I’ll have another go in a few days on a better, longer road and see if I can reduce the wheel spin and improve my gear change.

My car is totally stock. Sport / Goodyears.
About half a tank of fuel and temp of 30C just now.

Do you have any idea how Draggy is calculating a 1ft roll out? This is normally done via the distance required to cross and leave a drag race "line" via an optical sensor.

Draggy is what...just doing some math with an accelerometer to get an approximation?

Im not surprised to see these figures 4.88/4.63, and that with a 440 tune for 8k extra! This is all it does.. around the 5 sec mark, and thats bad. To get close to the claimed figure of 4.3 you have to dump/destroy the clutch on a perfect day with the perfect driver.

The numbers should have build in margins and make those claimed numbers even with average to good driving skills.

What you are saying doesnt make any sense. First you state you cant get the car to do 0-100 in under 6 sec. Now you say you are not surprised to see the figures below 5sec with a 440 tune while the guy posting the numbers clearly stated that his car is stock.

And finally after several videos and people stating that they messured around 4.5sec you are saying the numbers should have built in margins to be legit…?

If car manufactere publish Laptimes of the Green Hell, should they let average joe drive the car so the times are legit?

Seems like you are on a mission here…

You might want to try re-reading my post again.

Particularly the last paragraph.
