🐒 INSANE 500HP VAUXHALL ASTRA VXR TURBO REVIEW

Full review of Grants absolutely insane 500HP Vauxhall Astra VXR! With a fully built motor, giant Pulsar turbo, nearly 2.0 bar of boost and a chassis to match this is one crazy fast car that is a true force to be reckoned with! We don't think he quite realised how fast it was! Not only was he scared but John was also just as scared when they swapped over, pure madness! Sit back and relax as we take you on a crazy fast ride full of turbo sounds, exhaust pops & mental Vauxall noises! Really hope you enjoy this car review, make sure to give the video a like, share and comment to keep the car reviews coming! Much love, ML

🐒 SCARED FOR HIS LIFE! 500HP VAUXHALL ASTRA VXR REVIEW

The Astra H VXR engine (Z20LEH) is a development of the Astra G’s Z20LET power unit. Rather than simply diving straight in with remaps, we stripped an engine down to component form to examine its internals and get a real feel for what has been done. One of the main differences is the block has been equipped with oil spray jets. These jets cool the pistons by spraying oil at the underside of the piston. These oil spray jets were added for manufacturer's durability reasons because the LEH engine produces 240PS as standard (where the LET engine only produced 200PS), and not because, contrary to internet myth, the factory Z20LEH engine runs lean. In fact the Z20LEL and Z20LER engines used in Astra H run at the same target lambda value from the factory as the Z20LEH engine, and the LEL/LER engines do not have under piston cooling.

The pistons themselves are high yield forged items with the skirts Teflon coated to reduce noise and wear. Gone are the Z20LET’s counter rotating balancer shafts. This sharpens response whilst helping the engine rev much more quickly. At the top end the inlet manifold is revised however this revision is across the whole of the MK5 engine range, the VXR though getting new larger injectors. The turbo charger is a hybrid item, equipped with a better A/R ratio and stronger bearings. The manifold it has been built into is cast in a higher yield of material making it less prone to cracking. This turbo unit has been available for a while now from Vauxhall and we have already used many times on the Astra G and the VX220 with good results.

Once we had established the above we then under took mapping our first VXR. The results are very good, however we could not take the car any further than this on the standard intercooler. So extensive cooling modifications were investigated and developed for the next level of power, to ensure the longevity of the engine and surrounding components.

The Vauxhall Astra VXR is a high-performance derivative of the popular GTC Coupe. It’s called an Astra, instead of a GTC, because Vauxhall is keen to highlight the difference between the two models. The VXR is a much more aggressive and performance-orientated car and under the bonnet lies a 2.0-litre turbocharged engine that produces 276bhp, allowing the VXR to accelerate from 0-60mph in just 5.9 seconds.

Many may not be entirely familiar with the VXR brand and that’s understandable because it’s not as well-established as the likes of Volkswagen’s GTI moniker. Originally the VXR name was launched with the Lotus Elise-based VXR220 Turbo. The badge and appropriate development was then applied to more mainstream models like the Corsa, Insignia and even the Meriva.

Those looking for rear-wheel-drive performance cars weren’t left wanting either, with cars like the VXR8 also included in the range. The first version of the Astra VXR was launched in 2005 and met with average reviews with criticisms being aimed mostly at an overly stiff ride and a general lack of polish. Its performance was unquestionable though and it attracted many fans thanks to its power and speed.

Volker Strycek, the head of VXR product development and a former race driver, made it clear about what his team wanted to achieve with this Astra VXR. “Our goal was quite simple: to be the best in segment.” Vauxhall also hopes this generation of Astra VXR will become the best-selling model.
