MMR is proud to offer its forged rods and pistons for the V6 engine family, we also now have a full line of forged shortblocks and head porting! Please see our website for more details!

[blown3.7]

are they in stock???

 

[Modular Racing]

Rods are in stock and can ship today, pistons are made to order and take Manley 4-6 weeks.

Any more info on the short blocks? I'm assuming that was in reference to the 3.7. I took a look at the site and didn't see anything.

I had two questions related to this subject...

1. Is anyone running a 3.7L with MMR pistons? More of a question for other forum members than MMR.

2. For MMR: Are there/what are the stroking/compression ratio options available on the forged rotating assembly?

 

[Smurf stang]

Are those pistons copies of the stock pistons?
Or do they have different lands and ring grooves?

At the moment just factory stroke options are available through MMR, as far as compression ratios we can do pretty much anything.

They are an aftermarket version of the factory pistons but made from Forged 2618 alloy and feature many design improvements including the ring land areas.

Are these used for NA application or turbo ?
In NA application can I expect any engine performance gains ?

1) Both.
2) Yes and no. It's not a straightforward answer. This is one of those 'if you have to ask, you shouldn't be trying it' things.

They said they can do "pretty much anything" to compression ratio. The pistons themselves will be heavier than stock, meaning if you copied the stock compression ratio (and essentially nothing changed), then you would have an ever so slight loss in performance from adding on rotational mass...

That's going to be the most drastic difference between stock and aftermarket. Pretty much looking at AT MOST 350-370bhp running stupid high compression ratios that would need a lot of support to manage over any amount of time.

Forced induction applications benefit from reducing compression ratio. The forced air charge makes up for it, when calculated correctly.

Thank you for the response and yes I am not really sure what difference these parts will make.
But after reading more on the subject I am convinced.

My plan is to go procharger very soon
Not going above 8 psi
Most folks run on stock setup.
So probably no need for this application for me.

1) Both.
