Had a good drive out with a friend today in his GT4. Had the chance to drive both cars back-to-back, and I must admit that Porsche absolutely hit the bullseye with both cars. Brilliant brilliant cars.
Bullseye, absolutely. Probably the best Porsche, taking money into account.AndrewD said:
Lovely day for a drive out in mine today.
Only 550 miles on the clock, engine still feels a bit lacking mid range. Do they loosen up?
Would have thought you would have covered more miles than that especially as you have driven to OZOnly 550 miles on the clock, engine still feels a bit lacking mid range. Do they loosen up?
The book says running in is around 1800 miles and then you can open it up, mine has done 1k and never been above 4K in any gear

I think that's why some USA guys have gone down the throttle body, headers, map route from Fabspeed, seems to be a natural mid range flattening of torqueOnly 550 miles on the clock, engine still feels a bit lacking mid range. Do they loosen up?

There does seem to be a significant difference of view regarding (the lack of) mid range torque between us and the other side of the pond - perhaps for understandable reasons. If we had been brought up on big V8s perhaps we would be equally concerned. Z4MPO said:
Voodoo Blue Spyder in Bicester Oxen yesterday 16/07/16! Looked epic I was in my black Spyder just about caught you up as I was getting on the M40 if you are on here. I was dead excited to see another Spyder sounded EPIC both looked amazing together with the roofs down!
That would be me. Good times!AndrewD said:

Lol it has more than a GT3 at 4.5k Only 550 miles on the clock, engine still feels a bit lacking mid range. Do they loosen up?
What you do want ? I know the 718 :-) it now has all the spyder running gear plus the midrange you want ?

mid range I think is fine its the top end "zing" that the motor really lacks in my opinion , I rarely feel the urge to red line mine and end up changing up early as it almost feels like its slowing down if hold on to the gear.
Once you are above peak torque in any gear the rate of acceleration IS slowing down of course - but this graph (GT4 - not Spyder - vs GTS ) might explain why the drop off is more noticeable with the bigger engine. Torque falls off above 5500 revs in the GTS and 6000 in the GT4 but the rate of fall is greater in the GT4 - and especially above 7000 revs. So subjectively a GTS is likely to feel relatively more eager at the top end than a GT4. Now factor in the loss of 10bhp at the top end in the Spyder vs the GT4 and it's perhaps not that surprizing it doesn't feel so eager at the top end. (The curves are for bog standard engines - W stands for wheel I assume)
nope it should have had the x51 kit for some top end. I have stated it's dead at the top and I have had my car 10 months now, one of the longest owners atm
But yet people poo pooed my early comments, now people want more top end lol
but one poster wants more midrange one wants more top end buzz, people have bought the wrong car if they want more midrange !
I have also see GT4 owner's say they don't like the GT4 at 3k revs ! FFS don't drive at 3k revs !!
GT4 owners would hate GT3's even more at 3k !!!
The older Spyder has more zing for sure, that 3.4 Dfi lump loves to rev out, it's far more rewarding to pilot and in the real world no slower !
The 3.8 lump is over rated imo in non x51 form for these cars ! esp a detuned one !
The USA guys have killed 5k revs BHP to get more 3k BHp and torque !! who ever sees 3k revs in GT style cars ?
on a blat I keep it above 4.5k revs but yes short shift as no point going to red line and it feels better to drop back in the next gear at 5k.
The engine does loosen up though so you do tend to a bit more up to the red line when the car has 3k miles on it.
Spyders and GT4 need a remap really and if you want more torque at the 5k dip also the throttle body.
I have been in talks and the remap seems a no brainer on these detuned cars, just who has the balls to make them what they should be ?
here is the graph, and as I said the throttle body give no more peak BHP but smooth's out that 5k torque dip better.
Its very tempting for £800

Totally off topic to Spyder / GT4 but on a plenum subject before I fitted ITBs on my Honda k20 powered race car I increased the size of the throttle body from 65mm to 70mm and match ported out the inlet considerably and played with inlet lengths and air filters and to my surprise the top end power only increased slightly 1 or 2bhp but did see a bit more in the midrange ,nothing really noticeable to me driving though, switching to ITBS 4x45 mm was night and day (despite every Honda forum you go on worldwide telling you they make no difference and not worth the expense ) with a gain of 20bhp from around 4,000rpm but levelled out at the top with only a 5bhp gain at 9,000rpm, the torque difference on itbs is staggering when driving the car which was the opposite of what I expected but thinking about it all extra air has to go through a 38mm port into the head so there will only be so much that you can do . I had to do a cam swap to lift the peak power .
