    Brands Hatch race 1 Brands Hatch race 2 Two terrible starts (not easy to launch a 4 paddle clutch up a slight hill, 6 paddle will be going in at some point) and front tyres that had started to de laminate so I had zero confidence in and didn't want to risk taking someone out. Thats the...

    Next up was Mallory park on the 10th of October, only 6 of us from our team racing this time but certainly a eclectic mix So this race meet was a complete disaster! After less than half a lap of qualifying the oil hose failed and spat oil every where and instantly ended my day. Oil line...

    With the car back at the workshop and looking over the car I noticed that the tyres had been bottoming out on the tops of the arch at full compression after turn 1 so decided to up the front spring rates another 100lbs as the previous 750lbs had at times felt too soft. New 850lb springs and a...

    Raced at Brands hatch indy circuit on the 11th of September Qualified 3rd and 4th for race 1 and 2, terrible start lost me 5 to 6 places into turn 1 and 2 so spent the rest of the race fighting for them back. Had zero confidence in the front tyres as they had definitely seen better days...

    Well the track day at Castle Combe was a success! The new calibration file for the vacuum parameters have worked and I no longer get the cutting out when on track. To say I’m relieved is an understatement, I’ve been pulling my hair out trying to get to the bottom of this fault for months and...

    So race day was full of mixed emotions, car was going well in qualifying despite traffic and I managed to get it P2 for both races which I was happy about. Race 1 and only a few corners inthe car cuts out with its usual fault codes, lost about 20 places but got going again and fought my...

    Back at the workshop I whipped the exhaust off and it appears the factory tacks had failed causing the outer collar to just come away. New flexy bought but this time I welded round both sides to prevent a similar failure in the future Noticed the mounts were getting a tad warm too so I’ll...

    Been lazy doing the updates again sorry. So after the above mapping session I noticed by the end of the day I kept getting my recurring fault codes so checking car over I noticed the loom Earth bolt had vibrated loose and also I had cracked the manifold again but not on the welds but on the...

    Been tinkering again recently and trying to improve the car ready for race season. Took her down to the test track in Bovington to do some more mapping to lean her off, good few hours tinkering before the dreaded fault codes popped back up more and more regular. Decided to build myself a...

    Agree, old one was a bit of a mess inside, but worked until recently. Still on M6 but next head has M8’s in it, I always wince a bit when I tighten the M6’s up as I half expect them to shear. I have 4 centralising inserts so they sit correctly at least.

    Decided to make a new engine loom in the hope to rule out any further electrical issues. Stripped front end off and some spare looms for there wires as the super charger loom is modified from standard and I wanted to make it custom to my bay and future mods. Stripped a good low mileage astra...

    Once back at the workshop I plugged the snap on in to try to find out more, fault was still leaning towards throttle body so I tried to rule out the pins being pushed out the back of the plug when pushing it on, was no different. tried a different pedal on it also. I did notice the pedal no...

    Been lazy with the updates so will bring it up to date now: Once back at the workshop after the track day I made a start on stripping the car down ready to sort the boost pipe issue. You can see the pipe has popped off at the bottom of the manifold so a re design was long over due. Also...
