I haven't had it installed yet unfortunately, but it's on my garages schedule for mid-June along with the turbos. As soon as I get some time behind the wheel though I'll definitely be providing feedback.

How are you liking the Richland wheels? I see your car's on their website.

Well hot damn, I made the cut apparently

Loving them so far, they definitely add that little extra something-something to the car where you can't help but look back after parking.

I would also highly recommend getting them ceramic coated; after having the 666m wheels, both the spoke design of the RF-GT4's and the coating make them sooo much easier to clean.

Incredible what you have done with the car. I am glad the car went to a fellow enthusiast. You are taking great care of her. I had to get another m4 about 4 months after I sold you this one. Got an M4cs, but miss that Manual so bad!

How does the car drive with 305 in the rear? Always wanted to go wider in the back as well.

Hey man, great to hear from you. I appreciate the kind words, and especially for allowing me the privilege of purchasing her from you. I've babied her since day one, lol

Glad to hear you were able to get into a CS too, it's just unfortunate that they never offered them with a 6spd.

So far she drives great with 305's, I was a little concerned with clearance but they fit perfectly. Grip concerns are effectively an issue of the past at this point, but I suppose the true test will be once the turbos go in.

And the wait is nearly over.
I'm scheduled to have the following installed the week of June 13th:

- Kratos KRAS55Bi Turbos
- EU5 Injectors
- Dorch Engineering HPFP Lifter Upgrade
- Clutch Masters FX1000 Twin Disk
- Auto Solutions SSK

For the sake of delta measurement, as I'm currently running a custom stage 2 93oct tune from Cary Jordan, I'll be getting a base line dyno this week so I can compare it to the results of the dyno tune session I have scheduled with Cary for later next month.

Flex-fuel 93oct and E85 numbers soon to follow!

Subbed can't wait to see how it turns out.

[MJ6]

Took the bastard to the dyno this afternoon to get a good baseline prior to the upcoming install and tune; I wasn't so concerned with peak numbers as I was getting a point of reference in order to measure delta later on.

This was on 93 octane with stock turbos, AR Design high-flow cats, TGM Equal Length exhaust, drop-in K&N filters, Mishimoto charge cooler/heat exchanger/charge pipes, tuned by Cary and adaptations reset prior to the run. It put down 483whp @ 6.1k and 506wtq @ 4.1k.

I'll be using the same shop and dyno for the remote tune in order to mitigate inconsistences between runs, and the only variable from a tuning aspect that will be different is that the current tune was road tuned while the Kratos tune will be completed via remote dyno.

[MJ6]

Updates

So I just got back from an unscheduled underway, but my shop was able to take the bastard in and complete the turbo, clutch, injectors and HPFP upgrades while I was out. I just picked it up a few days ago and the initial impressions are good; there's obviously some tweaking to be done tune wise, but over all the base map Cary provided feels solid.

Given the new clutch, I'm holding off on performing and WOT runs for logging purposes until after it's been broken in (approx 500 miles or so), but the remote dyno session is scheduled for the first week in Aug so I figure there's time to do it right.

On the subject of clutches, just in case anyone is considering the FX1000, although I've only had a few days with it I feel it was a good call and should be perfectly streetable once I relearn the new engagement points. It's a bit more sensitive to input from a dead stop (smaller window with the light weight flywheel) but perfectly manageable. One caveat though if you happen to have an Ultimate Clutch Pedal installed: the increased clamping force does increased the pedal stiffness by a decent margin. I initially had the UCP configured with the large over-center spring removed and the mounting hole set at its "hardest" setting (closest to the pedal); at stock levels it was great, but after stop and go traffic for two days straight my left calf was ready to tap out. Adding back in the larger spring and setting the mounting hole to the "softest"/OEM setting made a world of difference though.

Once we get it dialed in on the dyno I'll follow up with dyno graphs for delta comparison on both 93 and E85 tunes.

Any updates?!

I ended up switching clutches to the FX250 with the stock dual-mass as the FX1000 was just a bit much for my personal preferences in stop and go traffic.

Everything has been installed though; we did have to chase down a boost leak as WGDC was higher than it should have been, and apparently the 93 octane out here is horrible quality so we've had to play with a few different configurations and mixes to dial in the ignition timings.

Currently scheduled to hit the dyno at the end of this month to tune on full E85, so more results to follow.

Nice! How do you like the wheel setup and ET (aggressive)? Any rubbing? Looking to purchase the same set up and finish, but was thinking for the greater ET (less aggressive setup) to closer match the OEM front/rear ratio for TC intervention concerns/handling.

Loving the wheel set up, and no TC intervention to speak of with current tire specifications (275/35 and 305/35). The rear does poke a bit, but the Eibach V1 springs only provide a mild drop so there's no rubbing. The fronts did initially rub a little on full lock in the very front of the wheel well, but they're also a bigger profile and the ET is more aggressive. A little bit of heat gun action and persuasion fixed that minor issue though.

After long last, the beast has finally awoken.

Big shout-out to Avtandil at ABPerformance, this man is an absolute tuning WIZARD. If you ever have need of a highly responsive tuner that knows his way around the S55 platform, look no further. I can't recommend him enough.

We ended up with three maps:
- Map 1: 30PSI (high boost)
- Map 2: 22PSI (low boost)
- Map 3: Valet Mode (10PSI)

The final numbers were:
707WHP/687WTQ

Next up, Draggy times!

[MJ6]

Dragy times update.

We dialed it in for 60-130 dragy runs, and so far this is our best one:



The bastard has more in it I'm sure, but colder temps are making traction increasingly difficult. Compounding the issue is the torque management/shift bog that cuts throttle and boost in-between shifts and plagues manuals on this platform.

I just got my 6mt F80 and I have noticed torque cut big time while shifting under hard acceleration. Is there any coding or tuning that can be done to address the issue?

And the final finishing pieces to my build:

- Mashimarho Custom Steering Wheel
- Raceseng Stratos Weighted Shift Knob
