Blown 4-banger

Ok since I've been getting A LOT of PMs asking for updates on my build, I decided to make a thread so I can update when stuff with my build happens. Well, I'm pulling the motor this weekend. The big thing that happened today was I got the pistons squared away. CP Pistons will be providing the pistons. The pistons are forged (duh), 9.5:1 compression, dual coated (teflon sides/ceramic top coating). They will have valve reliefs to acomidate (sp!?) my cam setup. CP said the pistons should handle upto 850 hp, so I ain't worried about those bad boys wussin out like the stocker They said the pistons should be at my door in 4 weeks, I'M SO EXCITED!!!!!

cant wait man thats going to be sick

$0.00

Sponsorship FTMFW!!!

CP said they would be like $700-$750 with the coating.

NinjaHampster

how do you go about getting sponsored

Blown 4-banger

Well, with me, its through some connections with my dads company. Labor will cost me nothing, since I work at an engine building shop I have access to all the machines I would ever need.

NinjaHampster

alright thanks good luck with the build

Awesome dood, keep us posted!

Coblt ss super

dam dude thats good news, what is teh difference between forged pistons and regulars? sorry big time noob question

M-Dub

They are forged they just have coatings on the sides and top, helps with longevity and makes them slide better!

Well, cast (stock) pistons pours molten aluminum into a mold, the mold is opened revieling a piston. Weak, prone to crack/break under high stress. If they get too hot, they crack. Cheap to make though.
Forged pistons are made by heating the aluminum solid cylinder to about 800*F, then uses a huge press with like 20 tons of force to press a form into the cylinder forming the shape of the piston. This is a far better process, makes a much stonger piston, and when it gets too hot, it melts, saving internal parts from flying chunks of piston. However it is more expensive to make.

theres also a negativ ehtough....forged pistons are also heavier than cast iron pistons, and thus are not as well suited to high revving, but most tuners find this a very easy sacrifice to make, as few people like making power by revving to 12kRPMs....besides hondas of course

It's easy to get sponsored when your dad runs at Car TV show and a Magazine :-P Cameron get's lots of favors and freebies!

Z Speed

did they give u a part number........ once I get to this point in time I would like to order some high quality internals. Have you found any sources for rods yet?

SwizzDSMSS

Not Cast Iron, Cast Aluminum.

No new updates so far. The freakin guy from COMP who was doin my cams went on vaction until the june 13th

The guy from Ferrea is basically wating for cam specs so he can send off the valvetrain.

Pistons are still being made, they have about 3 weeks to go.

Dustin

you shud put a turbonator en et


But seriously, can't wait to see the outcome of this build. Good luck!

This will be an awesome build. Why not the 10:1 compression pistons? Is the 9.5:1 better for a higher HP setups?

Another noobish question, what about the diamond head pistons, I was told that they were better than forged.

Doc

92mm pistons @ 8.0:1 compression.
EVO stage cam (the same profile)
Ti valve train
port the head
neutral balance shafts
get the cometic head gasket
of course, get a good performance crank and rods.....that'll leave more than a few cars in the dust

since hes being given everything daddy wants and skipped the real answer, ive looked into it ill tell you. you have to go to shows already and win several of them on your own or at least place well. you have to show that you can get from show to show and let people see the car and their parts on it. you dont even get much of a discount at the lower levels. something like 10% of tires once a year when i looked into nitto. and you have to put a banner going across the top of the windshield.

Diamond is a brand of piston. You don't actually make the pistons out of diamond.

HViper

It is new Bling Bling for your motor. The block should be cast out of 24k gold too.

Ahh good blown. You can come over and help me install my SRP's when they come in.

10:1 is a horrible compression ratio for this motor with the Eaton blower. There is so much tendency for knock, UNLESS you use a 2.8" super charger pulley for the street, and then a 2.5-2.6" for the track.

The 10:1 will make more power than the 9.5:1 at the track, but will have to be so detunes for the street that the 9.5:1 will be faster on pump gas.

We had the Banana maxed out at ~430bhp on the Aeroforce scan guage with the 10:1 pistons and 109 Octane. On pump gas it reads 280bhp, which is worse than it was on the 9.5:1 ratio.

Seems like you finally got la bananna runnin We will have to race when mine is done, the banana on race gas, and mine on pump

Scythe_Snake

Woah.... -Rep on myself for my noobishness.

So, what compression ratio be better for compression that would run well with an y FI product (turbo, twinscrew, roots, etc)?
