Hey Ernie GN, those goals are easily attainable with a stock block. That's the whole big debate on this thread. Yeah it's a descent MPH on pump gas but that car had a fuel cell, fiberglass front and rear bumpers and a big intercooler just for starters. And it was built by Hennessy Performance, which adds up to big bucks...

That's my point.you could have run mid 10s on a stock shortblock.you shouldn't be losing the head gasket at that power level I have made a lot more power and kept the heads on but hey its your motor if you feel better about having forged everything than so be it.Well, I finally just popped a head gasket last weekend in my 10.4**, 130mph plus, forged stroker/cast iron head combo engine after 7 1/2 years of beating on it, so I think Lou Czarnota, the guy that built this one, did pretty good. Thanks Lou!
The next iteration he puts together for me will be even better.......
Have a good weekend!
Tucson AZ just this past November, engine is 7 1/2 years old with between 675 and 700 track runs and street blasts combined put on it before this run. Street blasts are just as hard on engines as full passes, they wind them up just as hard, just not as long......
22lbs of boost, a really shitty 1.75 60ft time and a crosswind at the mid/top of the rack of over 20mph. That affected the ET big time but it is the only recent time slip I could find laying around .......
The air was at over 3200ft that day.
I don't think she's bad looking, either.
How much boost would it take to do a run like that on a stock short block?
Boost is just a number.power is power some need more boost some less.compression, heads, cam,and valve spring,intercooler turbo all play a role.
Read my post.boost is just a number one motor can make 1000hp 18psi and another motor can make 1000 hp at 30psi,1000hp is 1000hp.dont think for a second the lower boost number will last longer power is power.
I have had lower intake charge temps at 35psi on bigger turbos than the smaller turbos at 22psi.boost isn't the enemy.
I know that.
I can agree with that.
Shit def happens.
Stroker don't make more power than the stock stroke in these motors,they just generally do it on a few less lbs of boost that's it.
Yes
adding boost is the same as adding CI
You need to remember that none of these Buick V6 engines make big power in and of them selves. They're small displacement engines in the grand scheme of things. They make big power because air is being forced into them. If you increase the cubic inches from 231 to 273 and use the same turbo you'll make the same amount of max power. The power production will be bigger at a lower rpm,but the max power will be determined by how much air you force through the engine. The max airflow won't change because the major contributor to airflow (the turbo) hasn't changed. As Mr.Spool said,max power will be produced at a lower boost pressure,but it will be the same as the lesser cu, in, engine.
This is partially true. If 2 Buick V6 engines produce the same power with different amounts of boost and cu. in.,they will exert the same amount of force on the crankshaft. The engine with the smaller bore will need to generate higher cylinder pressure to produce the same amount of force on the crankshaft as the engine with the bigger bore diameter. The work load will be higher above the piston but the same below the piston. I think the possibility of blowing head gaskets will be higher on the engine with the smaller bore,however I also think that ignition timing is the biggest factor when it comes to blowing head gaskets and exerting unusual wear patterns on the main bearings.
You know I would have to agree with this as well.
