bally4563 Posted October 14, 2016 Report Share Posted October 14, 2016 With all the available bolt on i.e 74 mm TB, 987 Airbox , stainless manifolds and a decent exhaust system, what do you think is feasible , just curious as to know how much Porsche strangled the 986? And that's without going down the under drive pulley and remap. Link to comment Share on other sites More sharing options...
C11RJC Posted October 14, 2016 Report Share Posted October 14, 2016 My 03 s (58k) had 265bhp on the dyno with all upgrade items mentioned accept the underdrive pulley, TB and 987 airbox. The 74" TB is now in (noticeable difference) and airbox goes in this/next weekend (supposed to be a pig of a job). Then back to the dyno. I suspect in the region of 280-285bhp. Anymore, I think you'd need engine rebuild work to chase that extra. Link to comment Share on other sites More sharing options...
Topbox Posted October 14, 2016 Report Share Posted October 14, 2016 Check out a few posts by @edc he's done a tweak or two in his time I believe. Link to comment Share on other sites More sharing options...
Jason986S Posted October 14, 2016 Report Share Posted October 14, 2016 300bhp at the fly is probably acheivable with all the mentioned modifications and a remap. Link to comment Share on other sites More sharing options...
edc Posted October 14, 2016 Report Share Posted October 14, 2016 I don't think you will get close to 300bhp flywheel with simple mods. The 3.2 in the 987 produces 280 and with similar mods including intake manifolds Berty has closed in on circa 295bhp. Worry less about the absolute number but more about the start and finish numbers. The gain is what's more important. Link to comment Share on other sites More sharing options...

When people ask what mine is running I usually say 260-270bhp as I just don't know (or overly care to as I've not spent any significant money chasing horses yet).

edc Posted October 14, 2016 Report Share Posted October 14, 2016 I've re-posted this a few times before but here's an idea of what you can get and do for basic mods. This gets circa +20bhp. @Mark Shead on a rebuilt to 3.4 and correct me if the spec is wrong, no cats, ebay manifolds custom 4 box design exhaust, larger throttle body and intake (not sure whether 74 or 82mm) and standard air filter box is at 309bhp. The 987 airbox is not the be all and end all. After all, on a 550 which is basically a late 986 engine with a 987 airbox it gets rated at +6bhp (or PS).

Mr96er Posted October 14, 2016 Report Share Posted October 14, 2016 Where would you use 280bhp? Mine left the factory 18 years ago with 200bhp or there abouts. Probly lost 10% of that or more over the years and yet it still has totally usable power for road use. if it's a number you're after, stick a hundred wet shot of Nos on your intake and claim 911 power. I had a 330bhp Lexus GS300 for up to 10 seconds at a time...????? I was young and dumb. Link to comment Share on other sites More sharing options...

mikefocke Posted October 17, 2016 Report Share Posted October 17, 2016 I was perfectly happy in an 85HP 914 and earlier Alfa 1.3L which had little more. To me the 200 HP of the base early Boxster was much more. But no reason you should make the same choice. To each his own.. Your money your choice. Have fun. Be safe.
