MG ZS track day car

July 20th, 2009

MGZSWe have worked with some guys in recent months in developing their MG track cars. One is an MGZS multi purpose family car come track day hack which interestingly is a diesel with enough torque to snap your neck thanks to a thoughtful remap and neatly installed intercooler. The other is an all out stripped bare and nicley set up MGZT V6. This has been built on a budget and has come to us to have some of it’s rough endges smoothed. With both cars looking good we headed for Donnington for some driver training. Wet weather made for an exciting day but great fun was had by all for a very small outlay.

Ferrari Exhausts

July 20th, 2009

We had a 599 Ferrari in or removeable custom track day cans.  Bit tricky this one because it had 4 tips and a tuning butterfly in 2 of them.  The system pressures were fluctuating from about 2000 RPM and it looked like we might need 4 cans.  In the end we isolated the tuned system, noise metered it and built cans to deal with the fixed system at minimum exhaust pressure with maximum back pressure from the cans. When the valves were opened the pressure balanced through the open pipes and the noise reading was spot on. Dropped it from 112 db to 94 db, still sounded lovely too.

stainless exhaust builds

July 20th, 2009

We’ve had some interesting exhaust builds in recently.  They’ve consisted of the usual fitting of universal back boxes and mild steel exhaust builds for those cars where a standard replacement is hard to come by.  We’ve also had a fair few stainless replacements for standard items too.  Generally most of our exhaust work is for standard sounding exhausts which will last a lot longer, look a lot nicer or just sound a bit fruitier without upsetting the neighbours. We did a lovely build on a Peugeot 206 gti which was suprisingly quiet given the power output. The total price for their lifetime guaranteed stainless exhaust was less than a standard peugeot replacement!  We had a lovely old Datsun Z car in for a stainless build which had a lovely deep note only a big capacity engine can give you.  Talking of big capacity we also had an exhaust build on a tractor of all things, again saving the owner several hundred pounds over a standard replacement.

Loud Lamborghini

July 20th, 2009

More Lamborghini’s in for track day silencers. Slightly easier this time as we only had to remove approx 8 db in a removeable end can. These were custom fabricated and tested for their effect on the back pressure of these very sensitive engines. All went well and away went more happy and slightly quieter customers.

Classic cool

June 18th, 2009

June 2009- An early 70’s Porsche 911 came in with starting problems. It had an old KKK mechanical fuel injection system on it so no point plugging the scanner in on this one! Turned out to have a small solenoid that literally dribbled fuel into the inlet manifold as you crank it over. We reconnected a broken wire and away it went. Stone age design and simplicity itself but it works.
Also in was a 60’s Mustang, proper old school american muscle. Just needed waxoyl and a few niggles sorting out. Nothing major but a lovely car and a perfect example at that.

Off Roaders

DSCF1493
Had a bit of rush on with 4×4’s. Had a few in for the usual high ground clearnce systems or just something a bit freer flowing but one was an all out racer. Sledge hammer simplicity and brute force that must’ve been great fun on the rough. Made a custom exhaust system with 3 breakaway joint so that if it gets grounded or snagged it will only pull off part of the system and not damage the rest. Looked good and sounded great.

Capri

January 19th, 2009

2008-Capri- work began in earnest on AA Silencers next race car.

DSCF1305What was originally a 1.6 Ford Capri came in for some major work. This started by completely stripping it to a bare shell. All major areas of rust were tended to, all none structural metal was removed and a roll cage fabricated. Fibre glass wings, bonnet and tailgate were fitted and a new lightweight wiring harness was made. A new cross member was fabricated for the front to relocate suspension and steering components plus engine mounts for the new engine. An inlet manifold was fabricated from scratch to take an as yet untried inlet system combination and an ECU was sourced for the ignition. The wiring loom was made for the ECU and all necessary sensors sourced and brackets and adaptors made to fit them as required. The engine was fitted and rigged with a temporary cooling system. A dash was made and wired in to monitor everything and countless other jobs were completed to make all of these parts resemble a car and stand a chance of working. In late 2008 the key was turned and it fired in to life. All of the prototype systems functioned and the car could be driven. Although there was a huge amount of development to be done the ground work was laid for what would be a tremendous racing car.

2009- Capri- Endless development has continued with the Capri. Wheels tyres, brakes, suspension pick up points, axle and drive ratios, gearbox, differential, anew cooling system, a new lubrication system, more weight loss, aerodynamic aids, a new fuel delivery system, a new exhaust, more testing and more set up work and finally it is ready to race! Fingers crossed for the end result but hopes are high.

September 2009- the big day has arrived, the first race for our capri. It was a 3 hour treck up to Cadwell Park near Skegness and we set up for the compulsary nights camping, BBQ and beer. 6am soon came around and the team were in full force preparing for Qualifying. The reward for their efforts was 3rd in class and no dramas with the car. It was a tremendous result from a new car at its first showing and all eyes were set on the race. Tension was high as everyone felt it was too good to be true, everyone knew there were always teething troubles and we were all waiting for them. A good start kept the car out of trouble and a super smooth pitstop jumped us up in to 2nd place. The car worked perfectly to the flag and the result was better than anyone could’ve imagined. Smiles all round on the long drive home and a thankfully short check list before the next race.

The Capri was put to good use at the final race of the year at Snetterton.  There were many new cars entered in out class and Snetterton is an open fast circuit favouring big powered cars, so we were concerned we may be at a disadvantage. Despite being down on power to the big Jaguars, Porsches, Lotus’s and Ferrari’s we still qualified 4rd in class. A good start and hard fought opening laps brought us up to 3rd and closing on 2nd place when suspension failure led to an early end to the race. New suspenson was designed and built as the car had to run the following week at a magazine’s track day.  The car impressed and we may be running cars for the magazine ext year. Watch this space.  It was good to see several customers at the track day and is something we are hoping to build on in the new year.
