Corsa E VXR Mapping and Full Exhaust

This Corsa E VXR came to us to have a full turbo back 3″ exhaust fitted, followed by map optimisation to suit the exhaust and full rolling road set up.

Once set up the results were an impressive 241bhp and 244 lb ft torque. We also carried out our own unique hardware fix and software recalibration to the air flow meter to allow it to read and fuel correctly above 222bhp, where it is known that the standard air flow meter maxes out.

We also have in development the CSR MaxAir Intake System for Corsa E VXR, which will feature an enlarged airflow meter housing and large AEM Dryflow cone filter.

Opel Speedster Turbo K06 and Inlet Manifold

This car had previously been in for a full engine rebuild with forged pistons and steel rods, strengthening the factory Z20LET engine and was running a K04 Z20LEH VXR turbocharger, Milltek 63.5mm exhaust system, Pro Alloy chargecooler and VXR injectors.

It returned to us to have some further enhancements which included a full 76mm Tullett exhaust system, a K06 turbocharger, Courtenay Klasen inlet manifold, uprated clutch and 80mm air flow meter.

After mapping and a full rolling road set up it is now producing 334bhp and 340lb ft torque, and is very at home on the track where it spends most of its ‘working’ life.

Astra H VXR Upgrades

Here we have a couple of Astra H VXRs in for upgrade.

The black car has had a K Sport 8 Pot 356mm front brake kit, CSRacing intercooler, full 3″ exhaust system and inlet plenum fitted and will be mapped and set up on the rolling road. It is also having a rear cage fitted along with eyelet provision for harnesses.

The blue car has had a Stage 3 package (CSRacing intercooler, full 3″ exhaust system), direct route hose kit and airbox, a Courtenay Turbosmart recirculation valve and a Quaife LSD and is also due to be mapped and set up on the rolling road.

Stage 3 Corsa VXR

We had a lovely 40 something thousand mile Corsa VXR in with us recently which had been fitted with a full 3″ exhaust system, twin silencers and pre cat removed and also our high flow CSRacing full height intercooler.

Compressions were checked all found to be good, then the ecu was remapped and the car underwent a full rolling road set up with full ecu datalogging and the software was optimised to suit the fitted components resulting in 240bhp and 249 lb ft torque and running on 99 octane fuel.

As we are sure you all know what a Corsa VXR looks like by now, we will show you the power and torque graphs instead:

If it was feeling ‘blue’ before it arrived, it certainly wasn’t when it left, after having a full 3″ exhaust system fitted, NGK iridium plugs, a panel filter, large bore inlet pipe and uprated recirculation valve followed by ecu remapping and a full set up on the rolling road with datalogging and map optimisation.

Corsa VXR Nürburgring Stage 2 Upgrade – Take 2

It has been a busy week for us for Corsa VXR tuning.

This Glacier White car is our second Corsa VXR Nürburgring Stage 2 Upgrade in a week. We fitted our full 3″ turbo back exhaust first:

Corsa VXR Nürburgring Stage 2 Upgrade

This lovely 2012 Corsa Nürburgring in Lime Green Pearlescent was brought to us for a Stage 2 upgrade, so initially into the workshop and up in the air so the original exhaust could be removed to be replaced with the full 76mm (3″) turbo back stainless steel exhaust system:
