DEA B3/B6 FORGED POWER PISTON KIT

[FestYboy]

I think what he's saying is he's too big of a guy to worry about unleashing extra hp.
Because it would be negated by his weight.

Finished off by his punch line

I never see a fat China man drifting...

Meaning if a fat man had more hp he wouldn't be able to drift.

It was supposed to be funny.

But what's funny is a festiva is 400lbs lighter than an aspire.
So theoretically if he had the festiva its likely he would free up that useable power and torque.
And it would be equivalent to a skinny man driving an aspire.

^ if that's the case, it would help to KNOW that information before hand.
at this point in the game, all most of us know about jason_ is that he's a member here, he owns a festy, and he milled the crap out of his head
i don't know anyone who has met him face to face yet (i know i havn't).

so it's all about context.... know what i mean?

I can't wait to see how mine turn out. They will be a tad different, to accommodate the BOOST and numbers I wish to accomplish, but still similar. Now to make some money and pay for the rest of my build... Looking great Matt, as always.

[FestYboy]

if all is well with your B6 Dennis, Scrappy may be the next to go under the knife (again) for an updated bottom end. otherwise i think the next project will be Caety's Aspire... it needs help like WOW.

[blkfordsedan]

I may have missed it, but what's the CD of these pistons? Is it stock for a B3? If a guy wants to build a B6, can you accommodate the shorter rod?

[FestYboy]

the B6 and B3 stroke are the same... no need to change CD.

:toothy8: i am seriously anxious to see your jonst in action again with the dickmyere slap and tickle in full effect up under that lil blue hood :evil1:

Better leave the specs to me..B3 piston has 1.173 pin center w/ 5.3605 rod lenght, B6 pisto has 1.253 pin center w/ 5.234 rod lenght both share 3.29 stoke.

[mattdickmeyer]

Not sure of your meaning. This I know ( in general) this is the rudest group of people i've ever done work for! Every thing I produde i've been asked to make , frankly because no one else can or it would have been done by now. Try calling Comp for your cams , or JE for your pistons or Carrillo for your rods, or specialty metal craft , for your headers and experienced getting laughed at!I make nearly nothing on what i build for you and it's just not worth it any more, I put off good work for this crap!

[navdoc101]

That was not directed to you Matt, but to all the bicthing & complaints. When I get extra cash you have several parts that I will be ordering. You've gone out of your way; in time & money; to supply QUALITY parts to a small audiance.

damn, there i go being half wrong again...

at least i checked my stroke :shock: haha

now given the above info, wouldn't we prefer the B3 measurements over the B6? longer rod, more compact ring package, etc. i've always wondered about running a modded bike piston for an all out N/A build (figuring lower reciprocating weight, tighter ring package, less skirt, longer rod... along with the B5 crank for a short stroke screamer)
thoughts?

Several major problems with using used motorcycle pistons...First, most all will utilize 4-valve relief in the wrong location. Secondly, motorcycle piston crowns are notoriously thin & wouldn't allow sufficient material thickness to machine for correct valve relief. Third, motorcycles usually have 16-19mm wrist pins, festiva has 22mm & there wouldn't be enough material to enlarge pin boss & still maintain sufficient strength. Fourth, the piston would be way too light, making the bob weight of the counter weights have greater rotating weight then the reciprocation weight of the piston. (this is called OVER BALANCING) Correcting this would cost $700+ in machine work alone, making my piston kit the obvious way to go.

Depends on the application, Arty. The longer rod has advantages in endurance racing or sustained high RPM. The shorter rod creates higher piston speed and promotes cylinder filling. Many different attributes for both, and I've heard different opinions on what the "optimum" rod/stroke ratio should be. It also depends on issues like head flow, cam profile, etc.. I think the B6 has a rod/stroke ratio that's closer to what Matt prefers. IIRC, he was making (or has made) custom short rods for the B3....Which was why I asked about the B6 rods. I'm salivating about the potential of a B3 (or B6) built with his custom rods, pistons, flowed race head, roller cam, header, etc.. I'm sure he has to be building such a beast!

[FestYboy]

ok, makes total sense there, and i expect that thought process to translate to the B6d and BP as well?

also i should have seperated thoughts in the previous post... given the numbers, it appears that the B3 has a better rod ratio than the B6? (longer rod for same stroke)
would this positively translate to the B6 as well? given that you're working on Dennis' B6, i immagine you gave that consideration, i'm just curious to your thought process on that (figuring side loading, average piston speed, etc.) I have no doubts that the carb B6 we spoke of earlier would require an enitrely different solution (especially knowing that the engine is destined to see 9000 rpm.)

*man, i need to learn to type faster lol

[mattdickmeyer]

I have very indepth answers for all your questions just not the time to type it all, you'll have to callme.
