Buick with V-6 Engines: Under Six Seconds?

**60dgrzbelow0** · 11-21-2009, 10:20 PM

With no racing experience whatsoever...but being an old drag racing enthusiast...and curious about what the V6 engines can do when wrung out completely....am I reading the elapsed times right that one of these Buick V6 cars is cutting the lights on occasions ...under Six Seconds? How is that even possible? If its true...that is just incredible! This series of track runs/Dyno test make me ask...what are they doing to get so much HP out of these six cylinder vehicles? How come they are not self-destructing?

Massive boost... running alcohol...

Brad is shooting for big power on a 3500, so we'll see what he does... He will go with built bottom end etc...

Boost.. lots of it.

that's what GN's are all about. Same thing with Sy/Ty's

the one advantage of iron heads...

What advantage is that?

**robertisaar** · 11-22-2009, 03:03 PM

the ability of iron to take massive amounts of boost?

**SofaKingWeToddDid** · 11-22-2009, 03:23 PM

but doesnt it run through a plastic intake manifold before it gets to the iron head?? plastic, boost and heat dont mix in my books. (edit) -the L27 i mean lol the GN has a metal intake im sure, and i dont know about the syphoon mix there, but im willing to bet its not plastic. i wouldnt turbo a 3800 for a daily driver anyhow.

PSI is a measurement of flow and restriction. Most aluminum head motors that I know of are higher flowing than iron heads for the same setup. Perhaps I am ignorant of a such a market, but I know it is not the case for 60V6s. The big blocks used for racing that I have seen are aluminum block and heads.

That might be of interest

aluminum heads will take just as much as iron heads, just avoid detonation.. lol

My guess is...if the engine compartments were just a wee bit roomier... You guys would be trying to stuff a Turbocharger on each bank of every V6 on the lot! LOL.. I have to say... the performance is absolutely stunning and I'm really surprised... Thanks for the heads up on "Boost" its amazing what "...just one more atmospheric pressure ( + .3 PSI) will do..."
