New RRM Pistons!!!!!!!!!
so rrm's new part is aluminum forged pistons. 799 for 4 i dont know to much about pistons and such. but what kinda gains could we see if a set was installed in an RA.

well heres the grocery list of ?'s i got so far
1. what hp gains can we get and at what rpm's
2. will this give his gain above 6000 rpms (we need it badly there)
3. Are pistons the "weak link" in the mivec engine in which if we replace the stocks with the forged ones, we can maybe throw 9 lbs of boost with the turbo kit???
4. drivability. noisy? rough?
thanks... if the gains are somewhat decent, and it allows for higherboost (by itself, w/out rods or anything else) i'll buy them first thing after winter... i promise, and Rob should know i dont mess around

I wouldn't expect gains if they are the same as stock but only stronger. They would be helpful if you were going F/I though. Anyone know where you could get beefed up rods and head pins to match?

if they're lighter it should give gains right? im just assuming, im not sure...
anybody have numbers on this?
and if you have ONLY the pistons, u think you can add a pound or 2 to what RRM has aready, or you can only up the boost with the other mods???
thanks for the help

I am in the process of finding high compression/low compression fits for the RA, but if anyone else knows these, it would be great to know.
We should get all this information in a single thread that's easy to find....a sticky perhaps?
....IMO RRM knows they can charge that money because there're so many people that are sold on the company already, plus they right out have a dedicated mod base for the lancer vs pretty much anywhere. They're in it to make money too....although on the pistons....ALOT of money, hahaha.
I do like their wide band though, it seems pretty reasonable, though I haven't put a lot of research into that specifically.

you dont need to "find" pistons you need to have them done that is why people can find more affordable prices..
you might want to try:
arias and ross for pistons and crower for rods.. all custom it should be for all in the neighborhood of 500 to 650, if you dont want to think buy them at rrm
what all companies ask for when you want to go custom is the car (duh) engine make model and year, bore size, stroke, rod length and material desired, block height, compression ratio (and were you want to get), gasket thickness & diameter, wrist pin diameter, pin offset and direction, application info (aka: "mods"), induction & fuel, camshaft specs (gross lift, lift @ TDC), valve angle, combustion chamber CC’s, valve diameters & freedrop (valve edge to cyl. head deck)
same is for rods...

You would need to send them a piston to get them done.
As for our pistons, forged aluminum, stock bore and compression. Improvements to design and construction are key. Thicker ring lands, especially at the top ring. This will allow piston to tolerate more detonation. More boost is possible but remember, detonation is detonation, and fuel octane is fule octane. Those are limiting factors to tuning! Regardless, these pistons are designedto our specs and include all needed to install including, ring sets and piston pins.

So for anyone running a NA set up what benefit will they have with these? ANY? Or is this the kind of mod where you only notice the benefit once you get rods, thinner head gasket and raise your CR?
