JE sucks

[whenmunkysfly]

So i'm finally getting all my parts together and putting my engine back together after a total rebuild with the works. everything is going great i put my oil rings on. no problems. secondary rings. again no problem...but today is just not my day. i get to my top rings and what do i find... JE sent me five .020 over rings and one .050 over ring. wtf they cant send me all the wrong size they have to send me one and only one wrong sized ring. this ring is so big it fits around my piston without pulling on it. So now i must wait til tomarrow and call JE and correct them on their mistake and hope that they will next day air it to me so i dont have to wait forever to get my engine done i was hoping to get it done this weekend. i even bought the moly rings too. :cry:

 

[jdub]

I feel your pain...Ross simply left a ring out completely when I ordered mine.
Figured it out the same way you did :3d_frown:

thats why I tell everyone to buy wiseco's

 

[whenmunkysfly]

ummm...no thanks i have seen wiseco's blow holes in the piston for no reason on an N/A car.

thats why I tell everyone to buy wiseco's

 

[starscream5000]

No reason huh? And on an NA?! Um, no. There's got to be a reason for that one .

 

[hottscennessey]

Yup

 

[williamb82]

ive seen 60 over wisecos last over 5 years on a 7mgte with 20-25psi of boost from a t04e AND a 150shot wet fogger. pistons still looked almost new whe nthe engien threw a stock rod and was pulled apart. wisecos are the shit. ive NEVER heard of anyone having probs with them. and lots of locals run them, turbo, n20, blower, etc...

 

[whenmunkysfly]

well it was high compression. and i ment to say no aparent reason they never found out why id did it. of course there is a reason for it in one way or another.:icon_bigg

[JustAnotherVictim]

That just means they did something wrong. There are plenty of ways to counteract the higher compression.

 

[starscream5000]

:werd:

 

[whenmunkysfly]

yea i know they did something wrong. its just that from my experiance wisco's are a little weaker. but i've never tryed them on a supra so...

do elaborate please.

 

[starscream5000]

^ oh boy....

 

[JustAnotherVictim]

do elaborate please.

Off the top of my head, thicker hg and larger IC to lower air temps.

 

[starscream5000]

3mm MHG FTW!

 

[Boss302]

what the hades is the point to go higher then if your gonna drop it back down with a thicker gasket:icon_conf the whole point to raise comp. is to make the charge more volutile and thus more powerful. a intercooler would only make it more violent by densing up the air charge yeah it would cool it but there is "more air" so to speak and thus more to comp. and more to push that pist. down after the bang. unless you've got some money your gonna be opening that thing up more than regular cause it is so violent. no real way to counteract comp. cause it is a set factor. you don't do it unless you've planned it.

 

[JustAnotherVictim]

Yes the gasket will lower it but not to a point where the higher compression makes that big of a drop. Research knock and you'll see why lower air temps make a difference.


Just for you. Works the same on turbos.

Another way to avoid detonation is to cool the incoming air charge to lower the temperature inside the combustion chamber. On a supercharged application, this task can be handled by an intercooler (see "Let's Talk Intercoolers") or by a water injection system (less common). The intercooler takes the incoming air charge and passes it over a series of air-cooled or water-cooled fins and ducts, thus cooling the air in the same way that a radiator cools your engine's coolant. Intercoolers are thus very popular in higher output supercharger systems, where detonation becomes more of a problem. Often times, the intercooler allows you to run more boost and also allows you to eliminate the ignition boost retard, meaning you'll notice increased performance, and still experience no detonation. Another way to lower the temperature of the combusting air and fuel is to run cooler heat range spark plugs. Many supercharger manufacturers will recommend cooler plugs for you supercharged engine.

 

[starscream5000]

Detonation is due to the charge being too hot, thus igniting the fuel mixture prematurely. Cooler air, less likely to detonate .

 

[JustAnotherVictim]

Cold air is less violent than hot air. Molecules move slower allowing a more controlled environment.

 

[Boss302]

not the point. the air outside the piston, still in the intake has nothing to do with whats going on inside those cylinders the compression creates the enviroment as does the heat from what ever i'll give you that but the comp. is the main factor 8:1 vs 10.25:1 is going to produse less chance of detonation cause the enviroment is not so volutile. what i'm gettin at though is why counteract what you intended to do? if you want 9:1 why machine it and all that just to drop it? i'm not flaming or what ever you want to say but why state something like that when it counteracts your original intensions? thats my complex.
