If you open up the engine can you tell us if it's open deck or closed deck

Tell Neil Simon, Brian and Woody Hair, that Jason says hi. Ran many years with these guys and I know they've done the one lap in a supercharged Mcoupe and more recently a 1M.

Good luck, I will follow the results.

Im thinking that if you are truely that hard on brakes then why not add a brake cooling duct from the front and add a powered fan to blow air on them. While it wont prevent overheating totally it will slow it down considerably. The weight should be minimal.

Surprised you are having cooling issues, on my 235, fbo, never gets hot runs hotter in traffic than on track. That's in 90 deg plus temps doing open track for the full tank of fuel ( I use the car to run the tracks I will be endurance racing at this season for seat time).

I do run meth water, at a very low nozzle (two cm 3) for keeping intake temps down, and removed some restrictions cowling for better air flow. Not sure if that would help the m2 or not.

Sebring, RA and CMP are tough tracks to put down good times with little to no seat time. CMP is like an overgrown go-cart course, your mods will do well there, Esp. for Brakes. Sebring and RA take some time to get the commitment in a few turns since, well, concrete walls.

I would do one lap some day, but would have to be west coast, southern driving, that route in FL, total snooze fest. VA is the worst to drive in, maybe just take the Amtrack auto train

Speaking of details, 5 May is around the corner...will the car be ready in time?

90% chance we will not be opening the engine on this build. Turbo and fueling will be the furthest I go, and to be honest I am not sure if that is truly 100% sorted for track use yet.

Brake ducts are pretty high up on my list to figure out how fabricate, but this platform will be a challenge. A fan wouldn't really help that much at speed and would actually reduce the "ram air" effect, but the issue here is that I am going to have to fabricate some kind of proper backing plate. The easiest thing to do would probably be to cut the stock backing plate to fit the caliper, and then rivet a brake duct hose to it. But it is very tricky routing hoses to the front bumper for inlets without limiting your steering angle.

Having tracked the standard N55 and the M2 N55, there are definitely a few differences. The standard N55 I was able to easily overheat once I put a Pure Turbo on and upped the boost. The M2 has better cooling stock for sure, but if you log the coolant temps you will see that they occasionally hit the threshold where the car will begin pulling throttle. It doesn't throw a code, but what will occasionally happen is at the end of a high speed braking zone after a 3-4-5 pull, when you hit about 40mph the airflow through the radiator drops and coolant temps spike. This causes the transition back onto the gas to be really bad as it's pulling throttle and power. Once you get moving again temps are generally okay. You won't really notice this as being a result of overheating unless you actually log the coolant temps; usually people just attribute it to the car acting weird or DSC if they track with it on. I hate it because when you enter a corner after late braking with a GT3 on your tail, the absolute last thing you want is for your power to be cut when they aren't expecting it! Could be dangerous.

I am actually really interested to hear more about your experience running water meth on track. I was seriously considering running a meth kit but with pure water specifically to keep IATs down as opposed to relying on it for fuel. How has the system treated you? How often do you have to refill on track and do you run pure water or a weak meth blend? Thanks!

We are running the event one way or another. There are a couple of parts that will be cutting it extremely tight, like the AP Racing rear kit and some of the new coolers for CSF. But if the new parts are not ready, I will reinstall stock for the event and then continue the build towards the track season and SEMA. I intend this project to run all the way through the year right up to the show.

Finally someone doing a proper build.
Also, I'm surprised I haven't heard about "One Lap of America" and I'm even more surprised some popular automotive Youtubers haven't done it. It sounds epic and much more enjoyable than those typical rallies.
Can't wait to see what there is in store for this car dude, good luck. Cheers

Question about the AP brakes... I have a set of AP racing brakes on my Z4M with Pagid pads and they are great on street and track. https://www.apracing.com/product_det...5575-1010.aspx

My Z4M kit are no race calipers and I was also told that racing calipers like the ones in your kit have a lot of downsides on the street? True?
I have them on the car for 5 years and they have zero issues on the street with salt, road dust and other street things. The AP kit you are talking about is a purely race caliper...would this be a good idea to use this in the street? My cars are 85% driven on the street and do around 8-10 trackdays (Nurburgring visits) a year.....and I'm a heavy braker

As a multi-time One Lap of America participant, I'll look forward to following your progress. I'm very interested on the Essex/AP brakes performance.

My F80 is jealous about those.

Good luck and have fun!

Good question! I have not gotten around to coding it yet, but I have began the process of poking around in various modules and seeing what I can find. Luckily, as a M-car there is not the intrusive level of e-diff intervention that there was in my old X1. But I very much intend on coding off some of the braking crap and other safety nannies, some of which do carry over ffrom the e9x generation cars. I will do a whole post about that down the road, but it won't be until the car is back up and running again. Until then I will enjoy following along with the stuff you have started exploring as well.

Well, here is the thing about using a street system on track - the dust boots will distentegrate anyway in the first session. I would say that all things being equal, a brand new street caliper has more protection against the elements than a caliper like mine does. But the instant you burn up those dust boots on track, the street kit actually becomes worse than the race caliper because the debris from the dust boot tends to make a mess and get stuck in the pistons.

People often get confused between a dust boot and an actual seal. All pistons in all calipers have seals, otherwise brake fluid would leak out. But dust boots are only found on the street, and become useless once used on track.

I do not anticipate any issues using these calipers on street at all, and it is something I have talked to Essex with to put my mind at ease. I just plan on making sure the piston area is clear of debris and on giving it a light wipedown every time I change pads, which is something you should do anyway on street calipers as well.
