How much boost can a 2G Stock Head & Bottom End hold up to?

[greathuskie]

for me its 14.7

I wasn't talking about stock cars. I thought that would be obvious, sorry. Here's a guy that ran 13.6 with 18 PSI. Do you think he would run 13.2 at 22PSI?

He also has o2, downpipe and catback. That makes a *pretty* big difference. There is no point in comparing modified cars.

OK now you've got me really confused. Do you think that the guy (Larry D I think)with the dyno graph that you posted had a stock car and that he made those numbers by just turning up the boost on a stock setup with no other mods?

Look, I don't want you to worry, so I'm going to turn down the boost. Ok? I've it set at 15 psi right now.

Good answer. I wasn't trying to be confrontational in any way. I was only trying to understand your point. Sorry for the misunderstanding.

Yeah i second that,

IGS: you need to get your head stright and get back on topic

I'm running 23psi on a small 16g with 85,000 miles on the engine. Most of the time I run 100 octane but not always (93 octane otherwise). You guys seem to be going overboard on this crankwalk thing because some 2g cars NEVER end up doing it. I've got a friend running 30psi on his FP Green on his stock bottom end and no problems. He also only runs 110 octane though.

 

[Violater101]

Timing is the key I'm running around 19psi on the Green with occasionally 1 degree of knock around 6k or so with around 18 degrees of timing and an A/F of 11.4:1 or so. I would get more than this, but the ECU is pulling a degree for intake temps over 84 degrees and 1 for coolant temps from 206-224, otherwise I would be getting around 20 degrees. I may richen it up a tad and add another degree or so if I can keep the knock away.

Man it's difficult to not type stuff that would get me kicked off the site when you spout out your bullshit. Do you just type this basackwards bullshit to get people to argue with you and then reply with one or two words for fun? You are the epitome of ignorance.

Where did I reply with one or two words? What was your question? Ask a specific question I'll give you a specific reply. Looks to me like you're the one just posting bullshit.

everyone talks about there motor blowin...why wouldnt u just upgrade the rods and everything before that happens to prevent it from messing up other things?? its not very expensive to buy some je pistons and crower rods and install them..u guys sound like u really know what your talkin about so im sure it wouldnt be a problem...maybe im missin something i prolly dont know half of what u guys do

Not my question retard.

How about the one word reply of "myth" on the first page of this thread. Or "old wives tale"....yeah, those are real specific replies. Maybe you could go into detail on these one word replies with your wealth of knowledge and experience. Oh...wait....you don't have any.

All everyone here is asking is for you to back all your 1 liners: "myth", "old wive's tale" with some facts when you're asked. If you're going to say its OK to run 25 PSI on a T25, then you better be ready to get called out by people. All I was trying to ask you was if you thought it was OK for someone to run that kind of boost on a completely bone stock car with no supporting mods. There are people running mid 13s on a T25 but their car's have supporting mods on them that are usually equivalent to a 16g setup. I think you are getting so defensive that you're missing my point because I don't think you're that stupid to think its OK to just crank the boost up on a stock car. Its posts like that that let newbies blow up their new cars who read this.

Crankwalk can not be prevented by building up your motor. I've seen guys that have built up 7 bolt motors and had them crankwalk. My car has no signs of crankwalk. However, at this point, I'm alot more worried about throwing a rod and destroying my engine because of the power I'm making. I'd love to get a fully prepped race heaad and sheet metal intake manifold. But I'm not going to spend all that money on a head just to have a stock rod go through my valves. Yes, forged internals would fix this. But on a 2g, doing this to a 7 bolt is just plain stupid because you can put $1000+ in a shortblock that could crankwalk at any time. I, like many others, plan on swapping a 6 bolt that I can build up to withstand the high horsepower but not have to worry about my investiment crankwalking after 200 miles.

 

[greyforestgst]

ive heard 22psi before

i run 18psi daily with no problems yet...will prolly crank it down to 17 or so, and bump timing (somehow).

 

[Mike 99GSX]

18s alot different than 25.

What more proof do you want? You want me to drive my car to your house and show you? Have you personally ever run 25 psi on the T25? Now I'm calling you out.

 

[Mike 99GSX]

I must be illiterate. Do you race your car? Does all that carbon fiber stuff you have listed make you go faster? How old are you? I'm guessing 16-17 tops. Do you have any ET slips to show how fast your car is at 25PSI. Look, I know that I don't have the fastest car on this board and that their are people here more knowledgeable than me. I'm here for 2 reasons: to learn from people the things that I don't understand and to help people who have been in my same position if I know their answer. Maybe I shouldn't care, but I have a problem with people saying stupid things like "I run 25 PSI on a T25 with a stock setup". Like I said, alot of newbies who are very naive come here for info. It sucks that someone will probably blow up their car tonight because of your ignorant comments. I'm done with this one.

You guessed wrong.

I don't drag race.

So is that a yes or a no? You still haven't answered my question. I've answered all of yours.

You make my eyes hurt, before posting please read every thread taken place in this forum

HAHAH 25 psi on a t25...that just cracks me up. igs spouts more BS on this board than anyone I talked to before. So hes either lying of is an idiot. I guess hes never even heard of an efficiency island or anything like that. In every post where people call his BS, he gets defensive and spouts the same BS short responses ("myth") that dont answer a goddamn thing. You should all see his post on AT vs MT cars...Ridiculous. But thats getting off topic...

Basically it will get you NOWHERE to boost 25psi on a t25. The tiny turbo will generate so much heat that you car will in the end, end up pulling away your ignition timing. And no timing = no power. Hot air is less dense than cold air. If a turbo is pumping tons of scorching hot air, then less actual air molecules reach the engine, which more air and fuel = more power.

Now prove to me, that a t25 at 25 psi is a good thing, compared to maybe around 16...Tell me EXACTLY why, not just your shitty 1 word answers. I gave a full description of why its a bad thing, you tell me in detail why it works.

 

[loreak]

he cant tell you why because everything he says is bs, ive already argued with him in a post over his blatent stupidity and he shut up because he got shut down tough

if you ran a t25 at 25psi it would hold there till about maybe 5k or 4.5, if it could even make it to 25psi....which it probably couldnt, and if it did you would probably detonate or melt a piston

 

[Keaka26]

actually, ive argued with him in several posts, but I try to treat each one seperately, this is the first time I've brought up other arguments....

But yeah, regardless of the fact that he was wrong/right, he still acts like an assh0le so he gets treated like one...
