Twin Turbo VXR Monaro



 

 

 


Europes second most powerful Monaro - Maybe?

Another crazy turbo project!

Once again, we have been asked to produce another turbocharged monster car. Not quite as hardcore as the last one, but pretty serious nonetheless!

Car will feature Twin turbo custom 7 litre engine, with air to air intercooling, electronic boost control, twin 3 inch exhaust and uprated clutch and driveshafts.

In a vain attempt to get this onto the ground. The rear end will be mini "tubbed" to allow larger width wheels to be fitted.

Stay tuned for further updates on this project...


Old Engine removed - no longer required!

 

With the old engine removed, most of the remaining parts on the underside have been removed. As well as numerous uprated parts, this car will also be receiving our rustproofing process.

The new 7 litre engine is currently being built by Knight Racing Services in preparation for this monster turbo build.

To help get this extra power on the road, wider wheels are being fitted, in this case 9.5 inch wide wheels with 285 section tyres. In order to do this and ensure the proper clearances right up to the bumpstops, some remodelling of the inner arch and slight relocation of the trailing arms is required. There will be no external modifications.

 

 

 

The pictures show the initial trial fitment of the new wheels, prior to arch cutting taking place.

Measure many times, cut once!

 

 

 

 




The important thing with this work is ensuring that clearance is maintained throughout the full travel of the suspension. The neccesitates fitting the wheel and tyre combo with out spring fitted and lowering the car all the way too the bumpstops to check clearance. Time consuming, but the only way to do it.


No going back now!



 

 

 

 

 

 

 

 

With the metal cutting excercise over with, the underside was treated to our full rustproofing process (see our HSV Maloo project page). Subsequently all the running gear was put back.

With this done, it was then time to reassemble all the running gear. A new set of AP brakes were fitted along with a Pedders Coilover kit, Rear End Pac, Road Response Pac, Pedders Quick Rack and adjustable bushes in the trailing arms.

Fitting these adjustable bushes allows full manipulation of the both camber and toe settings at the rear. This allows us to reduce the amount of rear wheel camber to increase the contact patch, which along with the new 285 section tyres will make a big difference to grip under acceleration - essential on this car!


We got so excited getting the engine back, (put together by Perter Knight @ Knight Racing Services) that we forgot to take some progress pics! The one above is the best we can offer, which shows the new turbos in position along with the new twin plate clutch + plus a lot of pipes and cables!


Another couple of shots showing the new APS intercooler and a general view of the engine bay. As can be seen not much of the turbo kit is visible, adding to that stealth effect.

With the main installation completed, attention has turned to fitting an electronic boost controller. Along with the revised Wastegate spring, this will allow different boost levels to be selected. So that the customer can see how the engine is performing, we have also fitted a pair of Scan Gauges

The car is now up and running, and will be handed over to Paul at Wortec for mapping of this beast to be completed. Stay tuned to see what this APS turbo kit and a custom built 7 litre engine can do.


***UPDATE 26.02.10***

Well, its back!!!

Power is now 747bhp at the rear wheels.

Out on the road this is an awesome car. Extremely little lag, totally docile when required and brutally quick if required.

To back this up, the owner, on completion of the car, took it to a standing mile event where it ran a 193mph.

That's right 193 mph from a standing start in one mile!!!!!!!!

In the quest for ever more power, the car is back for further modifications. Watch this space!!

 

***UPDATE 21.06.10***

Well, those further modifications have commenced!

Ulitmately, maximum power was being hampered by the design of the exhaust manifolds.

In order to overcome this, new manifolds were required.

Not a an easy ask, given the space and location of the turbos. But achieved nonetheless.

Whilst not really visible in the car, here is a pic of it on the dyno.
