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 heat effected zone next to the weld, so off the inlet come again to be welded.


While it was off I decided to convert it to M8 bolts rather than the M6 inlet bolts.
Got myself a new oil cooler as I hated the fact it was covering the intercooler and was very susceptible for a stone strike so ditched the removable slam panel and riveted it to the top of the rad. Got some hoses made up and had to tweak the rad height slightly and tiny lift on the bonnet pins and it just fits under.
lots of nice clean air still behind the cut out grill and now the intercooler gets full cold air coverage.
also made up a new side panel for the bumper to channel the air into the cooler so that nothing is wasted.


Final mod before the trackday was to move both front and rear cameras as they are very wide angle and hard to get the angled right so they don’t look miles away.
moved the rear one 6”s further back and the front about 3”s so videos should be better quality now.


So on the 20th of May I was at Snetterton 300 for a track day, morning was dry but rained after lunch so hot to test in both conditions, car was going great, once or twice every session I was going into the limp mode but that’s way down on before so I’m going in the right direction at least.


Went to do a final session and the flexy joint decided it didn’t want to be attached anymore, was odd as car driver into pits fine but failed during cool down so loaded up and called it a day

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 have to keep any eye on them as well


Found a major flaw in my solid boost pipe off the inlet design, despite the engine being practically solid mounted it clearly still moves more than the silicones at the intercooler could handle and split the intercooler underneath. Also got the cracks on the sides again so checked the flatness of the charger face and length ways it’s fine but across the face it was slightly distorted causing it to sit under tension when chargers bolted down so once modded it’s off for a skim.


So new design was to go back to the silicones underneath but allow more gap between hoses to they have the silicone to take up any engine rock, done that at both ends so should be fine now.
While I had it cut up I decided to re weld everything so welded inside seams as well as caping runs on the outside too just as a precaution really.
Sent it off for proper machine skimming then re added the heat tape


Noticed the gasket is larger than the inlet so got the die grinder out and sorted that, also removed the lip that sits inside the LS4 throttle body.


Inlet and intercooler pipes on you can see the new design with the silicones better

Also noticed the top coolant hose was just weeping from an old scuff so bought some new and got it all back together


Final mod was to move the rear toe link bracket as exhaust V band clamp had been hitting it on full compression of the suspension, so chopped it off and moved it lower, made a joining plate to box it off.


Car now just needs a re geo, bonnet vents re sticking as silicone I used has not done the job and a wash and it’s ready for it’s first race on the 17th of July at Snetterton on the 300 circuit.
