SINGER ANDWILLIAMS AIM FOR 500HP

Porsche restora­tion gu­rus teamup with F1 to cre­ate the ul­ti­mate air-cooled flat-six

911 Porsche World - - News And Views -

Singer Ve­hi­cle De­sign, those Cal­i­for­nia-based restora­tion wiz­ards with a line in what you might call the ul­ti­mate in resto-mod­ded Porsche 911s, have an­nounced a new col­lab­o­ra­tion with Wil­liams Ad­vanced En­gi­neer­ing to cre­ate what could be the last word in air-cooled flat-six power. What's more, the en­gine has been cre­ated with in­put from none other than Hans Mezger. Yes, that Hans Mezger, the brains be­hind the orig­i­nal Porsche flat-six.

The mod­i­fied flat-sixes Singer al­ready puts into its cars were al­ready some­thing spe­cial with ca­pac­i­ties up to 4.0 litres and out­puts around 400hp. But it seems the new en­gine will op­er­ate on an­other level al­to­gether. For starters, an over­all out­put of around 500hp or the same as Porsche's very finest wa­ter-cooled flat six with nat­u­ral as­pi­ra­tion is be­ing mooted.

The spec­i­fi­ca­tions are noth­ing if not ut­terly com­pelling. The most ob­vi­ous change to the en­gine it­self in­volves the in­tro­duc­tion of four­valve heads, some­thing Porsche never man­aged to achieve with­out the ad­di­tion of wa­ter cool­ing. Other de­tails in­clude ti­ta­nium con-rods, alu­minium throt­tle bod­ies, dual oil cir­cuits and an en­larged fan. The net re­sult is that epic 500hp out­put along with a stun­ning 9000rpm rev limit.

But that's just the be­gin­ning. A fur­ther in­trigu­ing de­sign tweak in­volves a new car­bon-fi­bre air box and res­onator so­lu­tion. This as­sem­bly sits atop the en­gine and con­nects to a pair of se­ri­ously slick in­takes that are in­te­grated into the rear side win­dows. Singer says the ex­haust sys­tem has also been thor­oughly re­designed in ti­ta­nium and the two cen­tral out­lets have been re­placed with a pair of much more widely spaced pipes.

Rob Dick­in­son, Founder of Singer Ve­hi­cle De­sign, said, “help­ing our clients re­alise their unique vi­sion with the help of au­to­mo­tive roy­alty is very much a priv­i­lege. Singer is de­lighted to be work­ing with Wil­liams Ad­vanced En­gi­neer­ing and Hans Mezger to of­fer our clients a 'next level' of restora­tion and mod­i­fi­ca­tion ser­vices for their Porsche 911s. With care­ful and ded­i­cated devel­op­ment, this iconic air-cooled en­gine has much to give both its ex­ist­ing devo­tees and a gen­er­a­tion of new en­thu­si­asts.”

It's said the new en­gine will first be in­stalled into a car for se­rial Singer cus­tomer Scott Blat­tner, who al­ready owns two Singer­mod­i­fied coupes and a Singer-mod­i­fied Targa. More de­tails of this lat­est Singer spe­cial should emerge in the next month or so. For now, pric­ing for the new en­gine is not quoted. Could be pricey, though!

Singer has joined forces with Wil­liams Ad­vanced En­gi­neer­ing to cre­ate a new air­cooled, 4-litre, flat-six en­gine. With 4-valve heads, ti­ta­nium con­rods, throt­tle bod­ies and a be­spoke in­take sys­tem. Power should be around 500bhp
