Indeed. It's relative to quite a bit. I was ignoring the previous 35psi comment, as it's a bit of a blanket-statement... Unfortunately, there's a huge misconsception that boost equals power. On the stock twins, when people learned I ran 22-24lbs of boost, they'd step back in awe. I currently make more power at 15lbs of boost on my setup at the moment. Boost is only a measure of the restriction in the system (IE - Heads/cams/valves/piping/intercooler/etc) A stock longblock supra may make X hp at 30psi, change out the cams, and proceed to make that same X horsepower at 25psi or lower. It's a change in the efficiency of the motor.
While I'm on it... This "Stage 1/2/3/4/5" Bullsh*t needs to curl up and die.
I understand that in the IS300 realm, it makes sense, as the manufactuers are limited, and all very similar in offerings. Within a particular like minded/like owning crowd, it makes sense... When a Honda/Chevy/Ford owner asks me what stage I'm running, it get's me a bit irked - Not that they're curious, just that they've been so unknowingly blindsided by this ricer mentality. *sigh* So much more informative - "A 71mm wheel turbo on a tubular mani". Even turbo genealogy (of sorts) is causing me grief. 60-1's, T78's, PT67's, etc... While it seems of late, the main stream tendencies with the people I run across are leaning towards Precisions, too many ways to skin the cat...
Either way, the boost a car is running does not determine how far parts will fly should the block let go. (While it does impact cylinder pressures, the boost level itself isn't a measure of this, without a measure of airflow for the particular setup.) The RPM would seem the more likely place to look out for flying parts
(Clutch, flywheel, etc - Things that leave large holes in floorboards, hoods, and on unfortunate situations - people)
I guess I'll have to put the beer down now...
Just little things adding up to truly frustrate the hell out of me... The Evo bashing sounds like a good idea... I've still got some race gas in the Supra...
