You can't hit 19 psi on a stock turbo in 1st or 2nd gear, not even with the wastegate completely closed and a very free flowing exhaust. I'm guessing this was 3rd gear and up. He did say he has a Haltech though and that there is very high octane gas so it could theoretically be tuned so it won't blow up. I'm willing to bet however that the car made more power at 14 or 15 psi than it did at 19psi. Since I can't see his injector setup or fuel pump I'm not going to speculate if the fuel was there or not. Yes, the turbo can do 19 psi but it is far past efficient and definitely not going to be any faster. More boost is not always more power. Try 19 psi on a completely bone stock T-II and see how long it lasts. The results would be much different.

 

I said:
He said:
Stating he didn't detonate... yet previously he said not all knock is audible... but... if he had no accurate way of measuring if there was knock or not, how the hell does he know?

This has been my point all along. If Captain Hitachi over here was bright enough to practice his own medicine, and READ what I WROTE... or better yet, READ WHAT HE WROTE, perhaps he'd understand a little better instead of speaking in circles.

 

He has a walbro 255, stock injectors, stock fuel system, stock intercooler. Apperantly.

 

I see a problem with that.

 

OK, but...

Hmm, so let me get this straight... It was a "one time mistake" that you did for "at least a good 3 hours".

Because something is wrong here. Either it's the gauge or you. Take it or leave it.

 

I call BS. I have been in a customer's car, with him showing me how well it went, and watched on the wideband as the engine went lean and detonated at 13 psi.

Identical mods, save an FPR.

 

Ok..for the last time, it was a one time mistake ( as in, ONE IM NOT GOING TO DO AGAIN!? ). Quit taking everything so damn literally.

Like I said many times before, my gauge isnt off.


Forget it all. You all must be right. My car never saw 19psi. Hell, it blew up a long time ago on 15psi because the stock fuel system cant run much more than 11psi.

 

You can call BS. I dont really care. I know what happened and thats all that really matters. It seems nobody is gonna belive me anyways.

If you want a video of 15psi, Ill be more than happy to supply it, but Im not stupid enough to risk my luck at 19 again.

 

 

why not if you did it for 3 hours you only need to do it for like 10 sec.

 

Because I have nothing to prove to you all. If you want to go on living under the assumption that all the tribal knowledge you pick up here is correct, well...Ignorance is bliss I suppose.

I remember back in the day when ATF was the great thing to do. Now it hurts the engine.
I remember when 3mm seals > god. Now 2mm are the best.

If you want to think that 19psi isnt possible, you go on believing that.

 

I didn't say it was impossible. But just like everone else has stated it will start to hurt **** on your car. That would be BAD.

 

It is better to keep your mouth shut and let people think you're an idiot than to open it and remove all doubt.

 

Oh and if your willing to post a vid of 15PSI you obviously want to prove something

 

Why not? By your logic, since no one else has done it, you think it should be fine.

Either you admit your mistake and retract all of your above statements, or you stand by you statements that b/c no one else has boosted to 19psi before, and you got away with it, it must be fine for all stock fuel systems?

Of course I don't believe you. Why should I? I have watched a car running 6 psi less boost and more fuel mods run lean and pop a motor, watching the entire event an a UEGO lambda.

Your posts show a complete ignorance towards modifying and tuning a car properly, so I doubt you have the skills to pull this off. You don't datalog, monitor intake temps, A/F, EGT's, knock sensing, anything. I feel sorry for your car; its going to have a short life.

You're so quick to shoot down logic and answers from those who have been there and done that, especially in a case where you so define relaity and logic. No one owes you any answers; you need to explain how you get by the seemingly impossible, with the foremost question being:
How do you get the stock turbo to boost to 19psi?

 

Ha ha ha. You accusing us of ignorance. Come back when you have some experience with tuning.

 

maybe he's confusing psi with mmhg

 

Im dynoing tommorrow at 15psi. I guess my engines gonna blow up eh?

Seems kinda odd seeing as how its been running at 15psi for a couple months now...

 

When you get the dyno sheet upload it.
And why not run it at 19PSI if it PULLED HARD

 

for the record, as he stated, it was a trick question. he accidentally (but for 3 hours is still confusing) hit 19psi. like he said, its not efficient. hell, we'll say its making 100hp, fine. all he is saying is that he hit 19psi, i imagine on several occasions within 3 hours one night, and his engine still runs. also claims the compression is still good. i think the reason he wants the data is so he can see how. he mechanically knows that he hit 19psi with his given setup and, unless dwarves and elves switched his engine without knowing it, is still driving the same car with the same engine.
i believe him, personally. i guess it could be one big lie, and if i knew all there was to know about engines, i could try and mathematically find out just as he seems to want to do. but then again, the same year a man was said to mathematically prove that flying was impossible (1903?), a plane flew. on paper that plane never made it off the ground, but i'll be damned if anyone is gonna tell me i've never flown.

 

My vote goes for the elves. Fast and smart little guys. They must have dropped in a reman over night.

 

Im glad to see at least one person understands what Im saying.

 

4640rpm, 15.0psi, 190F coolant temp, 100% throttle, 104F intake temp ( hows that for the shitty stock IC? ), 9.928ms IOT, 73% duty cycle, 16degrees advance.


Id post a jpg of the whole datalog if I knew how to, but as of right now I dont...

But you said the engine was supposed to blow up? Hmm.....

 

Please post the datalog. Also, redo it and run the roms a little higher... I'd like 6500 rpm, thanks.

For triple the stock boost, you're sure not making more power, provided your datalog is even correct.

Yes, I would like more proof. But then again, you said you had nothing to prove? Pick a side, or you look like a hypocrite.

 

How in gods name are you only hitting 73% duty cycle? I've seen 90+% with 14psi and the AF ratio was sickingly lean (on the dyno w/wband)
