Why isn't there more turbo/supercharger conversions?

[anonymous-user]

Boosting a mid-engine car is only likely to end in a pile of trouble. Adequate cooling is virtually impossible unless you get into substantial body modifications.

Look how much bigger the side scoops are on a 718 compared with 981, even though 718 has a physically smaller engine and isn't even being asked to deliver big power.

Buy or try one, then come back and tell us if you think it is/you are missing 100-150hp, I'm doubtful you will. If however you do, you'd be better off buying a 718 and remapping that, rather than wasting your money (imo) bolting a turbo or a supercharger onto a 981.
IF you're that much of horsepower junkie, I'd fit a 3.8 engine into a 981 and tune it, but don't think for one moment a big engined or forced induction 981 will be easy to sell come resale time, or that you'll get back ANY of the money you've "invested" in the conversion.

I don't agree with all your posts but this one is spot on

I've had my 987.1 Boxster turbo for over four years and I've never had any cooling problems. Mine is a daily driver though, so maybe I don't drive it hard enough for long enough periods for it to become an issue. I'll have to take it on a track day at some point to see how it gets on.

Describe the handling characteristics. Actually don’t, I’ll do it for you...

Driven gently : Mild understeer.

Driven spiritedly : Understeer.

Driven as it’s maker intended : Terminal understeer.

Haldex ? I’ll take a proper front wheel drive car over a Haldex equipped car ANy day of the week.

For someone who bangs on about hating understeer David, you’re giving a lot of praise to a car renowned (even in its latest, light block 400hp version) for being utterly dull (and understeery) to drive (from a handling dynamics perspective)

I’d take an M2 or a 718 S EVERY time.

OP wants off the line and straight line performance, as did I at the time, my car did not under steer in fact under power it over steered.

As I said I did vmax events , its pretty straight line ;-) some times one needs a bit of poke to try, the TTRS is the best / cheapest way to get it.

A unmappped car is night and day over a remapped one as is one with standard geo etc.

remember I had mine way back 8 or 9 years a go, nothing else like it, it would out drag a mk1 Nissan GTR.

I loved it at the time, but after 2 years I got over the speed thing.

Am I to understand you're a Gen 2 991 GT3 owner now ?

because you buy a cayman for the NA tune engine

Apart from those people that don't. My neighbours wife has a Cayman and I bet she doesn't even know if it's NA or turbo.

Personally bought it mainly for the chassis. I (much) prefer the more linear power delivery of the (supercharged) Evora 410. Lag is never an issue with a supercharger - its just like an NA engine with higher air pressure - like an NA engine on a good day.
That said I think that heat would be difficult to manage with either a turbo or supercharger.
And it would make the car very hard to sell.

I might build one for my next project. Considered a 987 3.4 with a borked engine and diy rebuild, but then there's not must money in it if I were to buy a sound 2.7 (thicker barrels) croc, and fit a low pressure turbo install, the space is there for the turbo, scavenge pump, charge cooler, standard manifolds retained just need a Y pipe, that's £2k of hardware and some fabrication, say £2k for ecu & mapping and thats £4k build costs on a leggy 2.7 which might be £8k these days? General maintenance asside (I'd buy a 'dooer upper' regardless. Then I'm £12k in which is 3.4 money but less score issues. Granted it'll be more stressed but nothing more radiators and an air/oil cooler can't fix.

I'll go and hide now lol. (And start a build thread.. hehehe)
