Why can imports handle more boost than our cars with the stock bottom end they can handle more and even when both are modified you always see imports running more boost than domestics.

 

most of them came turbocharged from the factory, which means they came with lower compression, and forged internals.

put the same parts in a domestic and it can handle the same boost, as long as the engine is properly built.



another point of interest.........imports rev super high without probs

im guessing this is due to having overhead cams instead of a pushrod design........maybe OHC is better suited to reliable high rpm use.

 

So lets just say i built a fully forged best parts 396 with low compression how much boost can it handle with 93 octane

 

as long as everything is done right (engine, fuel, tuning)...........id guess whatever the gaskets can handle.

but someone with more knowledge/experience will be able to give you a better answer.

 

A factory forced induction car almost always can handle way more boost than our stock bottom ends. That isn't just an import thing.....think of Syclones/Typhoons, 03 Cobras, GN/T-Types/20th Anv. Turbo TA's, Lightnings, etc.

As for reving high, it has partly to do with their valvetrain setup, and also to partly to due w/ a shorter stroke design. But even then, I know of some pushrod motors that rev quite high. Have a buddy w/ a 355 that VERY regularly spins his motor to 8000 RPM, even on the spray. Solid roller cam.

 

rob raymer, running 25lbs of boost all day


whats funny is.........imports + 25lbs boost = 12's, maybe 11's

domestic + 25lbs boost = 9's, maybe 8's.

 

Depends on the breathing.. stock V6 turbo motor with 25 PSI makes 475 RWHP on 93 with alky injection. Do heads, cam, intake, intercooler..etc..same power at 15-16 PSI.

Breathing..boost is a restriction..open the bottle necks..watch out

Original question..lower compression..

Watch that octane requirement.. its a doozy if ya detonate at HIGH PSI

 

I hope you arent including DSM to that list, if you are then you are ignorant. A certain PSI doesn't equate to a certain time. Perhaps it was just a joke, if so don't quite your day job.

holy crap.........someone hurry..........we need the jaws of life...........this guy has his panties wedged too far up his butt

calm down man.............im speaking of the typical rice rocket crap thats out there running big boost and making pathetic ET's.

trust me, i have mucho respect for the DSMs out there that know how to put the power to the ground..........i almost bought one myself.

 

Titan motorsports supra runs 8.8@169 on drag radials

yes i know, its the holy grail of all the import/supra guys.

 

Titan is really not that fast compared to Paul from MSP. They went a 8.255 @ 170.90 this past weekend at E-town.

Jose

 

on bfg's or slicks?

 

I, myself, dont like supras, but this does tickle my fancy.



Go fast here

On QTP's
