718 GT4 - Have I lost the plot?

6.5k is peak BHP :-) it drops off then has a 2nd lower peak, what are you looking at ;-)
I should be asking you that question. Torque peak is 6500 but power is what really matters and is essentially the same from 6500 to 7400 ~390PS. Shifting at 6500 drops you far lower down the power curve on the next gear than doing so at 7500+.isaldiri said:
Ok so torque peak is 5900, I was mistaken. It doesn't change my point about power on the ground or that power is similar up to 7400
but powers less :-) on the 45 3rd party dyno's and when you drive them you feel that. GT4 offers nothing up topbut lets leave it as to go any more we need vbox data.

Jury's out on that one. Probably matters little, but was glad of the feedback, bemused by the arguments, and most appear to be making valid points aside from torque actually mattering very much. Power tells you the rate at which fuel can be turned into vehicle motion; the gearbox turns it into required torque at appropriate speed. F=P/v and a = F/m; torque is not even required to make the calculation.Aside from all that, optimum gear change point cannot be worked out from power and torque curves alone, much better to use the gear ratios to establish the tractive effort available in gears against speed. For lower gears in most cars it's quite often worth going to max revs even if peak power has been a fair bit earlier.

Plus.........
I drove mine to work today and it was ace. Three times i tried to put the radio on, then realised setting the climate to 22 and opening the windows was much better.
Sat in traffic for a bit, must have used the clutch 374 times. Foot didn't fall off.
Several adolescent kids decided I was a legend.
One bloke opened his window as I went past on a dual carriageway, then closed it as I disappeared.
Generally, today was a good day.
Not one person asked me how torque was calculated or where I should change gear.
Enjoy your car OP.
Excellent. I’ve spent all evening driving mine around also… no where to go… just driving… getting used to the new chassis configuration - with a slight adjustment in steering and seat position - have really settled into it now.

Got back home, parked up in the garage and just stood in there for 10mins, warmed by the heat radiating, listening to the exhaust ticking and brake discs pinging, as metal starts to cool and contract in the cool night air. Just looking around it, little angles and details.
Mega.

Excellent, I did the same thing last night in my base 718 boxster. Op, enjoy the new car, when do you take delivery? To anyone who can pump another £45k+ into their motoring hobby I take my hat off, and leave you with one final thought— after the GT4 what car will be next... It is an addiction..

Sometimes the combination of a load of hard work and more than a bit of being in the right place at the right time is a massive enabler - I do feel incredibly lucky to be on the cusp of owning something I was drooling over less than 3 years ago. And I have REALLY enjoyed the base 718 Cayman, I am sure the Boxster is equally brilliant. Should be collecting the GT4 by next weekend with a bit of luck.Next after the GT4 I want to buy my old GT86 back, complete with winter wheels and tyres, so I don't have to use the GT4 in snow slush and salt. After that, don't know, my name is down for a 718 GT4, but I am under no illusions that it makes it terribly likely I'll get a chance to order one.

Quick update. Collected the GT4 this morning. Clearly have not lost the plot. Compared to the 718 Cayman it rides harsher (Cayman was on 18" rims), is far less soundproofed, tramlines much more, and has no parking sensors. None of the above matter much.
It is planted, responsive, great gear ratios (less overgeared than the 718 for me), comfortable, perfectly weighted controls, but that engine! Response, wide band of torque, ample power, and it sounds amazing. I am going to slot right back into NA without any worries. It really is one hell of a car, and I feel zero remorse about parting with extra cash to have it in my garage.

As you say gear ratios are a key part of the equation too. The rather widely spaced ratios of Caysters are one of the reasons why the superior torque of the base 718 makes up for the superior peak power of the 918S and results in almost identical through the gears acceleration figures. Hope you enjoy your new car!Liam

er they are the same it does 85 in 2nd !
You are absolutely right, but I would not have believed it unless I had double checked. I guess it comes down to a 2.0 engine, vs. 3.8 making the 718 feel far more overgeared, as well as a slight lack of cylinders. The one with the bigger engine is far easier to drive in traffic, but you do have to get a bit more animated with the gearbox if you want it to make progress at more normal road speeds. I cannot believe how much more civilized the GT4 engine feels (and how much less civilized it sounds.)Liam
