Sportec Porsche 911 Turbo SPR1 with 858HP and 236mph - 380km/h Plus Top Speed

The standard Porsche 911 Turbo's 480HP 3.6-liter bi-turbocharged flat six is by no means a slouch, but where there's power, there's always space for even more power. Or at least that's what Porsche tuning specialist Sportec believes. The Swiss based tuner revealed a new version of its 911 Turbo based SPR1 that lifts the 3.6-liter flat six's output to a staggering 858 horsepower at 8,200 rpm and 642 lb-ft of peak torque at 4,800 rpm. Power is transferred to all four wheels through a six-speed manual gearbox.

Weighing in at 1,345kg or 2,965 lbs, the power-to-weight ratio is 637 horsepower per ton. According to Sportec, the SPR1 takes a mere 3.0 seconds to hit 62mph (100km/h,) with 186mph (300km/h) coming in just 18.9 seconds. The Swiss firm said that the supercar has recorded a top speed in excess of 236mph or 380km/h at Nardo, Italy.

Other highlights of the SPR1 include titanium connecting rods, a flat carbon fiber under floor, active suspension and F1 style ceramic brake discs plus composite (carbon / Kevlar) body panels, 20-inch forged alloy wheels, an integrated safety cage and a leather / alcantara interior.

APS Does it Again, Announces New Tunes for VW Golf R with up to 350HP

Now that Volkswagen has broadened the availability of the Golf R by officially confirming sales for North America, the tunes for the range-topping German hatch have just become a bit more interesting. APS of Brackley, has just announced three stages of performance tuning for the 2.0-litre TFSI, all-wheel drive Golf R, with two being available immediately and the third to be offered in a little while.

The British firm's Stage 1 kit consists only of a ECU remap, which is good enough to increase peak output from 267bhp to 308 bhp. It is priced at £445.00 including VAT (US$705 / €525).

The Stage 2 package is more comprehensive and includes a Milltek large bore turbo down pipe, high flow sports catalyst and a choice of Milltek stainless steel sports exhausts, featuring a switchable electronic exhaust valve, 2.75 inch bore tubing and dual 100mm ceramic black tailpipes.

APS said customers can choose between a Milltek non-resonated cat-back system, which emphasizes performance and "aural excitement", or a resonated Milltek cat back exhaust, which majors on refinement and also benefits from EC type approval. Depending on the exhaust choice, output is lifted to around 320-330bhp. The Stage 2 kit is priced from £1999 (US$3,165 / €2,355) fitted and including VAT.

Last but not least, APS is readying a Stage 3 package, which comes complete with a revised turbocharger boosting output to 350 bhp. The tuner said the kit is still in development but will be released onto the market soon.

In addition to the power upgrades, APS also offers a range of chassis upgrades for the VW Golf R such as a three way adjustable Haldex Gen4 four wheel drive controller, sports lowering springs, KW height and damping adjustable coilover suspension, uprated suspension bushes, Brembo GT big brake kits, plus 18 or 19 inch Sportec Mono 10 forged alloy wheels with Toyo tires.
