Full album on the M2 exhaust build

Super happy with how this stainless 3.5” exhaust turned out on this M2 comp! 🔥

To join the factory twin 65mm system to the single 3.5” tube, i machined a custom 3 degree mandrel to form the cones on to form a slick 2-1 merge.

I even managed to get everything nicely tucked up to avoid scraping the road 😎

Oh and also gave it a precise alignment using our laser alignment gear 🤘

Unfortunately at Japfest our good friend Matthew Denham had a gearbox failure on his samsonas sequential,

I stripped and inspected, ordered the replacement parts and after meticulously cleaning everything reassembled the box ready for more hammer 🔨

I also found a previous repair i had done to repair the input shaft with a shrink fit sleeve had failed and come off, so this time i opted to weld and machine the pilot bearing spigot back to spec to keep the clutch running true.

These cars get so put through so much, it is a constant battle to keep them tiptop 👌

To try and help it survive better in future i have added an external oil pump on an rpm strategy to make use of the oil spray bar in the gearbox to maintain lubrication on all the gears during extreme G forces 🤘

After the second test on full power running just over a thousand horsepower we had an issue with the heads warping on the outer edges due to the increased exhaust temps.

After inspection I realised the water flow coming up from the block wasn’t giving enough cooling priority to the lower outside edges of the heads due to the water ports in the gaskets coupled with the heads being weaker at that point then ideal.

The solution was to weld up the large water ports in that edge of the head faces and drill the heads and gaskets to match the blocks coolant passages, this increases the strength of the head surface that previously warped and greatly increases the water flow through the problematic area of the heads.

We are out testing this on new years eve so fingers crossed we have solved it 🤟
