Higher compression would need stonger gaskets, con rods and valve springs to. It'd have to be an entire NA overhaul. Wouldn't want a cracked rod. You wouldn't gain any power with forged internals unless the piston was domed.

 

i would think that you would gain some power. forged internals tend to be ligter than stock as well as stronger which would reduce the reciprocating mass/internal friction and free up some horsepower that way. probably not a lot tho

 

Forged pistons are here!!!!
$688 with rings. These are 9.5 to 1 compression ration. Primarily designed for our turbo engines but they will improve performance in NA engines and stand up to that silly NOS stuff much better. NOTE: the thicker top ringland. It will withstand a significant amount more detonation than stock! SWEET.
Special order item.

Declicious. Wait a sec though...isn't standard compression 9.5 though? No decompression on the block? Any weight savings over stock?

 

Nice !!!!!!

 

No decompression because want to maintain lowend power! Connecting rods are small. Prefer to not overrev motor. Instead nice smooth torque, no real lag and drivable power! If you drive our turbo with stock pistons you would know what I am talking about. This should really be nice.

I see in teh pic how the ring sits lower, wouldn't this increase the Compression Ratio to the car. I think that since you guys use low boost turbos, you should really consider building yourself a High CR, low boosted motor. Just need to keep your eyes out for a good engine management, but all in all it really would be smarter since you would take advantage of teh power gains from the higher Compression ratios i.e.: maybe 10:1.... The Honda heads are now trying the 10.6:1 CR ITR motors w/ turbos. Tuning is teh main thign though.

 

how high of boost can u run with new internals and a ic? aka these new things with rrms turbo intercooled kit?

 

so would these add any HP to an NA car

 

First off they don't come with turbo kit. They are separate. Boost levels? We will see won't we. Now at least piston is not the limiting factor. Next connecting rods. NA motorswould benefit from them because they are lighter. Have not weighed them yet. More info to come when I update the website.

i think you can run a good amount of boost with the new internals i mean stock it can hold a little bit

 

hey i'm just curious, was it design cost that kept you from doing 2 different pistons (one for turbo apps and one for na apps)? like i said in my previous post and you reiterated in yours, An NA engine will benefit because of the reduced weight, but really they would benefit more if they had perhaps about a 10.2:1, or maybe even a little higher, compression ratio. and for te turbo i was hoping for around 8.5:1 that would solve everyones issue with limited boost. is there any way that you guys could at least address this problem with a thicker and perhaps stronger head gasket? i usually prefer doing it with the pistons because then you can solve both the compression and strength/weight issues with one product.. also do you have any plans to release beefier forged con rods? or do you already know of someone (crower...etc) who is alreadyworking on this problm? also have you guys stress tested the crank? if so how much power do you think is safe to run on it? oh and one more dumb question; What is the total weight savings per piston over stock?
Thax i appreciate what you guys do

 

Have more to go on development. Maybe another piston is possible. Right now we are doing what we can to make turbo power. Head gasket (stock) on the Lancer is like a steel HKS style. Nice! Connecting rods may be in the works soon. Only 24 hours in a day and we use 23 of them!

cant wait to get mine rob... soon right? connecting rods... how much would those be?

 

Working on it. Your pistons ship tomorrow Yellow!
