What a shame I've heard decent things about the kit and the company is very backing of there product /: the price seems like a bargain to me plus the fact I can't source a DASC for the life of me haha

Disclaimer : i haven't used or seen in person the GKD kit. What I'm going on is my work with the mini Coopers that use that m45 supercharger. Its a smaller supercharger and uses a smaller pulley than the dasc kit. If you windup having a belt stretch or a tensioner start to fail this will allow the supercharger to slip on the Belt. This causes boost surge, especially at higher RPMs. This plays havoc with the computer, because when the belt slips boost drops and the computer tries to lean out the mixture, then when the belt re-grips, boost spikes faster than the computer can compensate. This makes a lean condition underboost which is a killer of exhaust valves. Especially when the Mini Cooper guys run the smaller pulleys to a boost. I've had to replace about 10 cylinder heads in two years on modified Mini Coopers. Now running this supercharger on a larger engine it will not create as much boost so this condition may not apply but I even have slippage problems on my other TI that runs the 15 pound pulley on a Downing Atlanta kit. Mine only fluctuates a few pounds when it does it. But with minis having a smaller pulley to start with when they slip they seem to drop about 1/2 if the boost. Hope this helps under stand my point of veiw on this setup. I also wonder what is the max boost that can be achieved by this kit and weather it can maintain that boost throughout the RPMs

After hours and hours of hand painting the head os almost ready for reassembly. And if you have ever wondered if you could drill a m44 head for 4 studs per exhaust hole, you cant. Made a jig and drilled on a old bad head i had and there is only about 1/4 in before coolant jacket

Hmm so should I hold off? Because I'm not looking for crazy power. Just 200 to the wheel and I'll be more than happy

Wow that is looking squeaky clean.

Got the head reassembled and plan on putting it on this weekend, just curious if anyone else uses the 6deg timing blocks for cam timing. It was a rare service bulletin tool for m44s that had rough idles and it also added a little more power. Just wondering if anyone else has seen this tool or used it. I aquired it from an retired bmw mechanic that had received it from bmw in the late 90s

Head is on and timing covers. Finishing up some mods to the valve cover and also fitting the supercharger. I have to modify all the brackets because I'm using a 5mm phenolic spacer on the manifold.

Can not wait to see this thing run! I wish more people would modify these little M4X motors. Especially in a Ti. A super/turbo charged slant 4 in these hatches is way to cool

Same here, my biggest concern on modding it had nothing to do with making power, but more with my own standard of wanting to be able to smog it any day of the week and it passing. The only CARB legal support for the m44 for extra power seems to be the DASC, which is already discontinued, even though Downing Atlanta has been very open to helping replace any misc parts or even printing out a CARB sticker if needed.

With the s52/m52 it seems with the aftermarket support a s52 at roughly 240hp can be modded NA to reach 280hp crank without much trouble, I don't doubt if the same kind of interest was had in the m44, building reliable safe street m44's that made ~180 and were fun would be more common.

Decided to drill the turbo bolts and safety wire them. I drilled the downpipe bolts as well

Looking fantastic man! Hope you're feeling better as well. What is the reason for the "safety wire" if you don't mind me asking?
