Whether it's a pet peeve of yours or not, that is how it's referred to...pounds
of boost (lbs).

Yep, he ran a 10.59 ocar n the stock '05 turbo, pretty impressive.

As far as 24psi being high boost it all depends on the car. For most new, high perfomance turboe'd cars 20-24psi really isn't that high. Now if you take a N/A car and turbo it normal boost is 10-15psi. High boost on an Evo, Supra, Skyline, etc. would be anything over 30psi with many reaching 40+.

You dont build race motors to last 50k. You build them to last the 1/4 mile, and if they last 50k thats just a benefit.
I didn't say they build race motors to last 50K miles. Obviously they only build them to last through the race Read what I wrote:

"Pushing that kind of boost on anything but a race car on racing fuel is just plain stupid. I can't see something like an Evo or STi lasting more than 50K miles with that kind of boost being fed into it."

And the truth of the matter is a street car wouldn't last 50K miles pushing that kind of extreme boost.

Well, I'll make sure to post up my mileage on my 40+ psi DSM. :shrug:

Just because it's referred to that way doesn't mean it's correct. They are both 3 letter abbreviations. Why not write the correct thing? Do you also say you put 24lbs in your tires? I don't think so. Lb is not a unit of pressure.

Sorry. I often write what I think out online and in person it sounds right but doesnt come out right online.


When I said how come V8s can run XX and XX It wasnt meant to be a qeustion it was meant to be a statment. Somtimes you cant express somthing online, fucken computers.

22-24psi is low boost on my car too. I run that on pump gas.


Most people dont get it, and then were the dumbass"s



I like how somone explain to me about a V8 making more power with less boost, and letting me know how this works. Lol I fully understand because my TA is going to be a turbo car once there are funds for it and when its time to build it. Right now its fine sitting blown up, I run 20psi on pump gas every singel day.


People 20PSI on a T25 and 20PSI on a 60trim are not the same, why are people comparing boost when they should be looking at the turbo.

I think I understand.

You need to get over it. Yes...we say 25 pounds of air pressure.

when in REAL LIFE you say I put 24 POUNDS of air in my tire you understand that they mean 24 POUNDS PER SQUARE INCH. When on the "internet forums" and you say 24lbs it looks different but you know they are referring to 24psi...Did what I said make sense or do you find that confusing?

Was that me explaining

I remember a thread way back where I tried for like 3 pages to explain that boost is not flow and that flow of air (best expressed in lbs of air per minute) is the key to making power.

It's still amazing to me how people think boost determines all. Its as if they think you could run a T-76 at 20PSI if yu can handle a 16G at 20 PSI.

nd of course the brilliance of people applying the same numerical standards to engine with half as many cylinders, different valve-trains, block matirials, compression, displacement and tuning.


It is all you can do.

Who called you a dumbass? It certainly wasn't me. But if you fully understand... why did you ask?

So... because you have future plans to make a modification that you currently can't afford, that makes you a subject matter expert? How's that work? And I have zero idea about what your next sentence is trying to say...

.....................

Anyway... not sure what's bringing the negativity on this one... I agree with the overall point of your post - that the turbo itself matters more than the psi. This doesn't need to become some weird bitchfest for no reason.

And Sparetire, my example was obviously a dumbed-down "all else equal" example... I realize such a perfect comparison doesn't exist, but it does illustrate the point quite well.

^NA, my bad. Your example was not far off really, I was thinking of other people than you when I was mentioning the whole boost with turbo A versus turbo B thing....

Low boost is like what stock Mustang Cobras put out, about 12PSI. Low boost is like what you would get with a turbo kit for an N/A car. I don't consider anything above 14PSI "low boost", thats ridiculous.

Pushing 30-40PSI is an awesome way to destroy your engine. Pushing that kind of boost on anything but a race car on racing fuel is just plain stupid. I can't see something like an Evo or STi lasting more than 50K miles with that kind of boost being fed into it.
Tell that to deisels that boost 50-60psi

Diesels are a whole different ballgame my friend.

Lets not get started with that, we're talking about import 4 banger's here, not Detroit Diesels with cast iron cylinder sleeves

You do know there are import diesels, right?

Yes of course, I was referring to Diesels in American trucks though. I mean seriously, how many VW Jetta TDI's do you hear about being modded out?? Not many, especially not with that much boost.

Who invented turbos? who were the first to use turbos? the europeans?
