V8 Engine Upgrades: Evolved Performance for V8 Vantage

At Bamford Rose, our intimate knowledge of the V8 Vantages development history and compromises required to get the Vantage into production provided the agenda for our engine upgrades. Focusing on the engine’s breathing; upgrades have been developed to improve gas flow into and out of the V8 engine improving the performance and responsiveness of your Vantage.

[BAMFORD ROSE PHASE 1 - FOR V8 UP TO 2010 - ENGINE UPGRADE DYNO RESULTS]

Bamford Rose Phase 1 V8 Engine Upgrade (For Vantage 4.7 2010 Model Year onwards)

Phase One of Bamford Rose’s V8 Engine Upgrade comprises of a primary catalyst delete (from the OEM exhaust manifolds), our airbox upgrade (for those vehicles without AM Power Kit – see adjacent tab for details), a remanufact of the OEM secondary catalysts and a reprogrammed ECU.

The OEM catalysts are remanufactured to from the factory more efficient, gas flow-optimised and constructed with high quality 200 cell bricks optimised for better performance.

At Bamford Rose, the remanfacture of the catalysts is not simple cut-out job as the engine ECU is also revised and the spark strategy mapping altered appropriately.

The alteration takes account of the different gas flow characteristics from the 200 cell free-flow catalysts (compared to the factory OEM 900/400 cell catalysts) optimising performance by running the 200 cell catalysts at the correct temperature. It also ensures that the engine diagnostics are recalibrated to ensure that no false emissions warnings are raised.

As an additional benefit a three-position switch for manual control of exhaust bypass valves (fully open, standard automatic or fully closed for those early morning starts).

This cost-effective package improves engine responsiveness from just 700rpm – not just at the high end of the rev range like our competitors – and delivers a benefit of c+15 BHP (or +25 BHP for Vantage with airbox upgrade) / +20Nm to engine performance. This package is suitable for all Vantages (2010 model year onwards) for £1,500 excluding VAT.

Bamford Rose Exhaust Manifold Upgrade

One of the largest compromises made to get the Aston Martin V8 Vantage into production, one very familiar to Bamford Rose team members working on the factory car programme at the time, was to use a “made to a price” manifold that fulfilled all global emissions standards.

This factory exhaust manifold fitted to both 4.3 and 4.7 V8 Vantage, whilst cost-effective for the factory is horrifically gas-flow restrictive, significantly compromising performance.

The handmade Bamford Rose sports exhaust package recovers the performance loss introduced by the compromised OEM part, delivering improvements to both power and torque and an engine which pulls considerably stronger over the entire rev range until the redline. The improvement in gas flow also allows better flywheel performance – the car revs much more freely and quickly to the redline. Finally, an additional benefit is that these bespoke manifolds are a significant 18 kg lighter than the factory versions.

Bamford Rose has achieved substantial performance gains by paying meticulous attention to design and manufacture detail of the manifold. The standard 4-2-1 factory manifold has been significantly improved by introducing:

  • Tuned equal length primary pipes of 4-1 construction.
  • A Bespoke Bamford Rose designed sequential collector cone enabling uncompromised exhaust gas scavenging.
  • Higher quality, 2mm gauge 316-grade stainless steel pipework with laser cut flanges.
  • Ensuring that all joints and bends in the manifold are fully purge-welded
  • (a gas is used to protect the weld seam until it has cooled to the point that oxidation does not occur, thus prevents cracking, corrosion and deformation).

As part of our uncompromising development approach, the manifold and complete exhaust system have been arduously tested around the world-famous Millbrook proving ground circuit. This durability testing created a thermal cycle which would accelerate the onset of any potential error state modes such as cracking. The durability has been further proven under road mileage accumulation tests where city driving, motorway cruising or spirited country lane driving have all been tested to make certain no error states occur as a result of the new manifold.

Bamford Rose Inlet Airbox Upgrade

The Bamford Rose airbox upgrade offers a modification to your Vantages airbox to improve airflow to the engine; helping it breathe more effectively at higher revs delivering c+10BHP.

The modification is similar to that utilised in the Vantage N400, which the team at Bamford Rose helped develop during their time at Aston Martin, it is however passively vented not valved as that airbox is. As an added benefit the airbox modification also slightly enhances the aural characteristics of the V8 engine adding a subtle menacing edge throughout the rev range.

Manifold and catalyst

Manifold and catalyst

The original OEM manifold design incorporated a big primary catalyst to pollutants created at low speeds/revs. This catalyst is very gas restrictive and at high revs, it would overheat of it wasn’t for the ECU being configured to run the engine very rich.

As part of Bamford Roses comprehensive engineering of this upgrade, the ECU is also recalibrated to remove the previous need to run the engine rich and protect the primary catalyst. The ECU calibration can be returned to the optimum for best power. Which result not only in better performance but better efficiency. This results in improvements in fuel efficiency. In the real world 17-22 mpg would be typical for the car; obviously dependant on driving style; with the upgrade 26-29 mpg is a more typical real-world figure. So with Bamford Rose not only do you get extra power but better efficiency too.

Available on their own to fit (see adjacent performance package tabs for fitment here at Bamford Rose) our secondary catalysts are manufactured to motorsport standards. The catalysts are more efficient, gas flow-optimised and constructed with high quality 200 cell bricks optimised for better performance. The catalysts are offered for delivery in either baffled or unbaffled style so you can tune your V8 Vantages exhaust note to taste.
