Chinese Stroker Cranks
What do you guys think about 2.0L stroker cranks at $1200? Complete rotating assembly around $2000? Using the same foundry as the Chinese rods and machining them here.
It will use standard b series rods, but will require special shortened pistons.
This is a concept I have been communicating with a 3rd party about. It could be a reality by late summer. However, it's a $30k gamble.
Discuss.

A $30K gamble? How many assemblies would you need to sell to recoup your investment?
What's the price differential versus what's available now? How likely is your target market to choose your product over the more expensive and better established competition?
I'm going to go out on a limb and suggest that the torque and power increases from .2L (12 cubic inches for cryin out loud) would be rather pricey at $2K. It's a lot easier to turn up the boost.
Are there that many guys who have reached the limits of the 1.8L, stock or with beefy rods?

That was 15 psi FMIV 1.8 vs 2.0.
Here is 12 psi FMII 1.8 vs 2.0

I want to note, I have no financial interest in the project. Don't be afraid to hurt my feelings...

I think with a low cost stroker crank, there will be a ton more all motor ~200 whp cars out there, as it would make as much sense to go all motor vs small turbo or sc for 200 hp. In fact, all motor 200 whp could be done for less than, say, a FFS coldside.
Just throwing it out there.

the difference between this kit and just a regular build is basically the cost of the crank. that's a reasonably small premium to pay for a 25-50 reliable hp increase "while you're in there".
however I bet FM charges so much because they wont sell enough to amortize the cost of making so few. but you dont need a business lesson
PS ***** to you again because I already have my parts.

Ben, I doubt 200whp is obtainable for less than an FFS setup. $2k for just shortblock internals leaves you a max of $2k to do intake, exhaust, headwork, the rest of the motor build, blahblahblhakljklsf.
It just reduces the cost of a 200whp beast from like $10k to $8k. Still retarded money.

Yeah I know.
My point was really more about the fact there would be more higher power nat aspirated cars out there, and that quite a few of those folks would have gone na over small turbo or sc.

i feel we are drifting of subject here with how much power you could make etc.
those who know the benefits that will result from these are the ones you need to talk to Ben, not those who question it!
I for one, am already interested, thats a fact, i've been interested!
Here is the obstacle, you have to get a lot of people (25 i assume) to make this happen.
We are not talking $300 rods, we are talking $1200 a pop here, so you are gonna need 24 more people you can trust that also trust you, that also know the benefits of this and that want to do it, no questions asked. I think it can be done, it will take time to line everyone up for it though, but it can happen. Right now, i do not have the money to put in this, but it can show up soon with the right influences...also, if you need help in negotiating a better deal for us, i would love to offer my expertise.

The company who I've been communicating with about pulling this off has its own investment capital. I need to show them that there is enough demand to justify their risk.
I gave the projected retail price. If it goes through, we'll do better.
Also, understand that you would also be required to run custom pistons, though we would get that worked out with the piston vendor, and they'd be retail ~$500 with rings.

I am interested, but i dont have a 1.8L so probably not going to happen for me.
Heres my concern, you buy the cranks but something fucked up in the process and know you have 25 cranks thats fail instantly. Whats your recourse?
If its FM i drive there and beat them senseless, or I cancel the charge and wait for them to make right. This is alot of exposure for the price.
