Any chance to add a couple more bearings in the crank shaft?

Coty is about to take it to the machine shop.
Apparently the flexplate is .75 Oz out if balance, and slightly bent? Not entirely sure how that happened.

Here is the bank one Pistons I decided to clean up. It's amazing what you carbon can cover up. The crack was already there. But look at the top lands of these things. Click image for larger version

Ok so today I was able to measure the clearances before sending off the rotating assembly, block, and heads to the machine shop. .0030 clearance on the rod journals. Manley suggests .002 min and .003 max. Because I'm picky and I think .003 is absurd, I need a .001 oversize bearing. It's either MMR or go straight to clevite. The main journals are at a consistent .0015 clearance. Stock is .001-.0016. Just waiting on some thick pieces of metal at this point. Click image for larger version

So I've been looking at this build and through my research it seems the weak point is the cylinder walls and the pistons. Has anyone thought about block posting these things? Its huge in many open deck blocks that have cylinder wall ocilation. If course not sure if this is possible with our v6's did to needing the posts on each side of the cylinder wall ive seen it a lot with the 4 bangers but they said it comes from v8s back in the day so maybe?

Not necessarily true. Cylinder walls are only a problem if you bore it, which is why I was trying to avoid that.
Sleeves have been developed for the 3.7, but for a very very hefty price.

Oh ok I thought I saw somewhere that the reason why some 3.7 were popping under boost was because the sleeves were possibly ocillating along with the pistons not being up to it. Good to know! Thanks

The weak points are the pistons.
That's what I blew on mine.

Not even the pistons, the piston rings. Boost + high compression is asking a lot of them though, so its hard to complain. It is irritating that something so little is what gives out. If you send a rod through the block its a pretty profound statement, but to break a ringland is just ... annoying.

I broke the piston. Tops on all of bank 1 were messed up. Cyl 2 was the worst

Very annoying. Especially when you break one and they were still reusable. Whole new set. Trust me, these 3.7 Pistons are cracked and rings are severely chipped.

Do you know if anyone has tried to tune each specific cylinders a/f ratio on the 3.7 yet? Btw love the build can't wait to see what is in store next. I'm wanting to run a borg Warner s366 when I get around to doing the turbo thing. Hopefully there will be a lot more information on it when I do get to that point.

No, it's done per bank, nor per cylinder. Because we only have 2 O2 sensors, 1 for each bank.

Right I understand most time you tune per bank. But they do have modules that you can read all cylinders at one time you probably just have to weld the o2 sensors in the exhaust manifold. but could help with some of the detonation problems everyone seems to be haviby. I was just wondering if anyone has ever thought about tthat and is it possible using SCT or Diablo?

Hassans tuner was a good one too, albeit with non VVT cars.. Aka corvettes, vipers, chargers etc. Most likely LPF tune wouldn't have grenaded his engine, but you don't have to go LPF if you don't want to. As I mentioned before, dyno tune would be your best bet - from a tuner who has experience tuning 2011+ mustangs. If yours is an auto, give Mike Rousch from Mid Atlantic performance a call.. See if he can help you out.

All I've seen him do were 3vs and 2vs XD
He's a ford guy.

I'll say that LPF would have known the little gremlins in the kit and known how to tune it. I mean, that was the point of calling LPF. but the tuner ignored that. Completely. Their kit is designed for their tune. That's just what I've been able to observe through this process.

Well....if I do it...after this I would just go to LPF. 1000.00 for the install and tune sounds reasonable!

Well that's not bad.
If you buy it, I can send it directly to them of you'd like. And they can inspect it and get the 2 brass fittings and clamp before install.

Most ECUs now days have fueling and spark adjustments per cylinder, but welding a $20 bung for a $200 wideband 6 times over is just silly. If you're really concerned about monitoring such things at the privateer level, welding an EGT node into each runner will cost maybe half as much and is equally effective at telling you what is going on inside the cylinder. People forget a tune is much more than just making safe AFR and power levels, its really easy to cook an exhaust valve with a poor turbo tune that is otherwise running safe AFR and power levels.

I have seen it reported by many shops (JPC, CPR...), and am still of the personal belief that o2 sensors should never go Pre-turbo. The pressure in an exhaust manifold will often be double what is in the intake manifold, and the pressure is reported to screw with o2 readings.

Well 3rd times a charm! Lol
Grade one bearings had .003 clearance
Grade 2 had .0025
We are hoping grade 3 has that magical .002-.0022 that we are shooting for.
We should find out soon
