yep got her all back together new disks are in and the tranny has a new in put shaft. also during the project i found out y my car was makeing shity power. the flex pipe in the ex. had calapsed down to about a 1" hole on the inside. so i made 430/280 on 1" ex. lol hopeing for a retune this comeing week and 600 on pump/meth

Awesome, i just finished installing direct port meth on my new motor.... GL

This is begging for some quote fix just can't think of one right now

awesome that's good to hear alex...you should have no problems making those numbers.

I wondered why nothing I did made any more power. Glad it was something simple - car certainly scoots for 1" exhaust.
-
fuck i almost shit myself when a looked at the inside of the flex section. but it explanes y my car was being so gay.
-
You almost shit yoyurself because you lack sphincter control from having a gaggle of fags run cock into that poor twat of a hole you call your anus.

I'll I'm getting from that terrible assemblage of words is you enjoy 1" loose anus's to fuck.

You've been here for years, Jeff. That hasn't become obvious yet?

got the 4" alum. ex. all set up and man is it load. get my tune on tesuday :yes:
-
load? as in; your face or LOUD.... as in... Me

Hahha, that sucks dude. Atleast it was simple. Your setup is gonna make the power now :)Recal

so i had her tunned today and all was going good she made 523/300 on just pump. made 2 pulls on meth/water and about the same power, sounded great. next pull it lost 40hp and 1/2 psi of boost. we add 1deg of timeing to bring it back up and she lost 15 more hp. wtf? looked at the plugs and they were fine. one more pull and its still down on power then as its idleing if you tap the gas you can hear a slight rod knock. gay.....
any one have a ls crank laying around?
-
i hear DBV gets crank for the low

With it dropping like that you couldn't tell something serious was going on?
-
couldnt it have been heat soak that can bring down power? maybe thats what they were thinking?
-
I'd have been looking further, but I'm just a bystander.
-
we thought it was the meth and it not wanting more timeing. we took all the time back to the pump gas setings (10ish degs.) and it was still down on power thats when we know something was wrong. >:(
-
any one have a ls crank laying around?
LS crank, and a brand new set of eagle rods... :noel:
-
In for pics of the upper rod bearing halves.

i just need 1 rod :-)
you have a pm
-
Man this car HATES you, WTF how high where you revving it
-
9.5k
and yes i think i might just hate me or it just really likes the garage ::)
-
9500? You might want to slip a GSR girdle in there while you have it apart.
-
im just tuneing at 9.5 to give me some head room at the track i think ill end up reving it to 8.5-9k
-
I'd still girdle it.
Cheap insurance.
-
just got her home. i will pull the motor out tomarow so i can see whats going on in there.
-

i have yet to see heat soak do that much change on the dyno. Typically very subtle unless you are doing some serious "hot lapping" without shut downs....which isnt exactly smart to begin with.
do you have an oil pressure gauge to moniter?
-
I wouldn't waste my time with a girdle.
-
i would.
-
The problem with anything spun high is usually the head, but girdle motors simply last longer when making power. Non-girdle motors make more power, however, at narfy's end of the spectrum 3% more.
-
im just going to do the things i NEED to to get the car back up and running. this is just my backup motor any way,i just want to to get me to the end of summer and ill be happy

rod bolts? no...?
-
can someone start a separate thread in tech and explain girdles, their pros/cons?
i understand them from an old fart v8 perspective, but i did not think they applied to hondas as much.
but their on the hype motors for a reason i guess.

and gsr. if i had one id put it in jsut to be safe but im not going to run out and buy one just becuse

Girdles, why?

Second picture - a normal 4-cyl sees almost 400% of the average torque on that spot of the crank each time the ignition fires. The crank can take the beating and uses the ductility of steel to deform slightly, but an aluminum block isn't a solid chunk. The girdle spreads the load, reducing bearing distortion and movement (both ovaling and overall block twisting). Why do you think the high-displacement, high-rpm K-blocks have a giant girdle, aka lower cassette? Forces square inside an engine relative to RPM, meaning 2x rpm = 4x internal forces.
It also has a bit to do with 2nd-order harmonics (vibrations). Ever notice how inline-4's 2.0L and greater have balance shafts and lots of lower block bracing? Basicly the crank vibrates up & down at twice frequency of the crank (double the rpm). In the first link below, look at the 2nd yellow picture labeled "inline engine". Specifically, look at the difference in length between "a" and "b". In the second link, the 4th graph (fig 9) shows secondary vibration (middle wavy line; note the extra from a poor r/s ratio). The text directly next to fig 2's top explains why. It's sort of a mind-bender, all stemming from a non-infinite cod rod length. That simple detail causes almost all of a inline-4's vibration. :/

Oddly enough, "boxer" engines are not vibrationless, and have these same vibrations. They're 180* opposed to each other so they cancel out.

Even Subaru?
