This is hard to hear when you happen to be the unlucky soul with the bum casting.That's a factor too. Some blocks are just cast weaker while others happen to be better. If you are lucky enough to have a well cast block it's potential would be higher.
and all off the shelf parts.
he is not the only one and there is alot more going on then most think.Fastest 109 out there is a stock stroke and it's well into the 8's. Nothing exotic according to the owner.
if the afr is in check depending on the weight of the car and power it made there are a few ways that would be a for sure sign.not sure he is there yet.As of now, our only guess is that he breached the strength threshold of his blocks power tolerance.
it ist’s obvious the whole package, engine, suspension, transmission, front to back is well thought out and thoroughly tuned.
i bet most guys just dont have the sack for it lots of parts cars out there but you really need to be able to push hard and drive hard for the good passses inmo.f it was that easy, everyone would be doing it.
thats what a good builder should look forThis is hard to hear when you happen to be the unlucky soul with the bum casting.
Not to mention the $$$$ needed. There's no such thing as a "budget" build to run 8s with a 109 block in a g body.i bet most guys just dont have the sack for it lots of parts cars out there but you really need to be able to push hard and drive hard for the good passses inmo.
very true.these things are money pits or as a friend says a labor of loveNot to mention the $$$$ needed. There's no such thing as a "budget" build to run 8s with a 109 block in a g body.
He data logs often and had a few logs on pulls just before the break. Nothing seemed beyond the norm. But sometimes it's just gonna happen, I guess.if the afr is in check depending on the weight of the car and power it made there are a few ways that would be a for sure sign.not sure he is there yet.
The engine was built by one of North-East's most reputable Buick builders. But I'm sure a detailed inspection of the new block will be insisted on with the next build.thats what a good builder should look for
Which leads me to my next question. How effective are these strengthening techniques when building short stroke, small displacement, high RPM motors? What can be done about the top end? Lifter valley? Main webbing?I truly think that once a person feels that their bottom end is "bullet proof" caps and/or girdle, the green light is on for test and tune. If our blocks would have came with 4 bolt mains from the factory, oh boy. I am glad that we have the capability to add a flat girdle to strengthen our bottom ends.
it can happen.i personally have had good luck with the 109,and havent broken one that way.nobody likes downtime.The engine was built by one of North-East's most reputable Buick builders. But I'm sure a detailed inspection of the new block will be insisted on with the next build.
The 3 bolt turbo I doubt is a restriction when guys are making making 1000 hp with them.The best thing that we have going for us now is component reliablity. We have the greatest electronics and electronic guru ( tuners) on the planet, non cracking heads, strong cranks and rods. Our 109 might be getting in short supply.Now we just have to scrap the rule book and get out there and turn it up. Get rid of the restrictor plate ( the 3 bolt turbo), gap the plugs and run race gas, NOS, M1, alky, E85, E98, or whatever blends. Blow some heads gaskets. Make sure that your supporting components can handle it and go for it with whatever stroke and bore that you have. I don't think ( it may be subconcious tho ) that I have a desire to go eights with a 109, I would like to have the reliability and the comforting feel to run low nines regularly, to stay ahead of a few things running around on the streets. Running 9's came easy, I just followed a recipe and put in seat time. I was literally told what to do over the phone and slow DSL. The thought process was to go as fast as I could with what I had first before I started trying to upgrade. I bought a ton of stuff that I didn't need and never used like a PT72 and 72lb injectors. Back to stroking and destroking. If there was any components that I could have back it would have been the 3.0 and 3.750 stroke crank. It would have been interesting to see the difference of max effort purpose built racing engines.
