Wpc is it worth it?

Well guys I've been doing some research on the wpc coating and from what I can see the results seem promising. I'm hoping that some of you have experience in using this method or at least some more knowledge on it. The plan is to get me transmissions hard parts treated during the rebuild to help them hold additional power. As well as potentially doing some engine components. If you have any info please share it.

I have to thank Performance Autowerks for offering this as an option on for their stage 2 f35 transmission, otherwise I would have never known about it. Basically it's the same as shot peening but with much smaller media at higher speeds. Biggest advantage over normal shot peening is the frictionless surface it creates while making the metal stronger.

My current f35 build is having this treatment done but only for input and output 3rd gears. The treatment for just these two gears is around $75. This treatment, along with heavily reinforced pinion and 4.05 FD should work well. I've already talked to Izumi @ WPC a day got my quote. Gears are ready to send off. I just need to decide if I want them cryo treated as that process must be done before WPC.

I was looking at doing that if/when I ever redo the trans I have in the car now after adding 4.05 gears. Was going to have pwerks do the whole thing. Got my 4.45 trans so it's taken a back seat for now. Don't want to have a $2500 trans sitting as a spare cause if something happens to the car no one would give me what the trans would be worth. I hear good things about it.
I was going to go with the cryo treat also. You might as well spend the extra and do it right while you are at it. You will only kick yourself later if you don't.

I'm pretty sure I'm not gonna do cryo treatment for a few reasons.
1. Cost. Most cryo companies base their pricing on weight. Cryo treating the entire gear set would probably cost about as much it would to WPC treat the entire gear set. I got a verbal estimate of ~$700 from WPC for the whole set. Not to mention shipping costs if you don't have a reputable, local cryo treatment center.
2. If the cryo isn't done correctly it WILL weaken the gear.
3. The main advantages of cryo are less friction and less wear. Imo, the gears are already exceptional hard and do not wear quickly anyway. Friction is my least concern as I feel the trans fluid takes care of the majority of friction. This is another advantage of wpc as well as it will reduce friction on parts that are already as smooth as glass.
However, there is not doubt in my mind that a proper cryo treatment will absolutely be more beneficial than not cryo treating at all. Especially if you do the entire gear set and syncro components. It's just a huge additional expense.

Pretty cool stuff. I can see the syncro working better and faster already

Surprised you just didn't send it to pwerks and just have them do it all? That's what I will probably do next year on the factory trans I have in the car now after trying out this 4.45. Also have a set of 4.05 gears for it from mongo.

He has the mechanical ability to do it so why not do it yourself? Its the same with me.

Wpc is worth it 100% ill post more info later

I like doing this stuff myself and I have trust issues so nobody touches my car/tranny/engine but me And In order to work on these trannies you have to make your own tools which I have invested in already. Also I like to set my preload/tolerances per my own spec.

Don't you work for Pwerks or something?

Damn I screwed up. I sent FOURTH gear(syncro/input gear) instead of third syncro gear. 3rd gear input and fourth gear output are being sent off for treatment now too. Ugh
I guess the bright side is that all four gears for 3rd and 4th will be treated.

Your subconscious made you do it. Just more insurance. More power to you for doing it yourself. Never tore into one of these granny's before.
