You mean what the induction system allows, with the cam complimenting that? Nice looking project BTW.
I think the big deciding factor for where I make my power will be the almost stock heads. Its kind of contradictory for me to have a single plane intake with a spacer on stock heads and a low rpm cam. I figure since I will be going with forced induction and plan to make a relatively small amount of power on boost, I really don't need to try for every last bit of NA power. My rods will fail or I will blow a head gasket before I run out of potential for more power. I am curious how this will perform without boost though. The single plane probably hurts power a bit, but I make a full point of compression more than my previous motor. I also have a tame roller cam that should make plenty of torque, and power up to 5000-5500 rpm. The fuel injection probably won't help power too much, nor will the Distributorless ignition system, but it will make turbocharging much easier. I think out of fear of disappointment with NA power I went 4.11s, looking back I should have gone with 3.55s or maybe 3.42s Please excuse the poor shape of my car. Bodywork or a replacement shell is next on the list... <iframe width="560" height="315" src="https://www.youtube.com/embed/KNFHmWvM9uk" frameborder="0" allowfullscreen></iframe>
That's AWESOME! Your car body looks fine to me, even more you did distributorless ignition AND fuel injection:TU::TU:
I shouldn't have ended my comment with a question mark. The way your engine behaves is almost totally defined by the heads, with all of the other parts factoring around that, boost included. I didn't mean to split hairs with your comment that implied that the cam determined much of the parameters, but it struck me as odd. Nice car.
No split hairs here! I appreciate any comments or advice. I still have a ton to learn, so I'm glad to have guys like you around to help out. In the end, I know I won't be making big power with the motor off boost. If I went 13.99 at the track I would be thrilled, that would best the old motor. As for where I make power I guess I really won't know until I'm on a dyno, which very well may happen at some point before forced induction.
Randall (thesilverbuick) is the resident EFI expert here on V8Buick. I used a lot of his methods and ideas for making EFI work on my engine. One of the few unique things with my build is using the GN cam sensor as I dont believe that's been done before. It's an athestically pleasing way to add a cam sync, easy to buy at any autoparts store, drops right in with no modification, and it's a Buick part which is cool. Using the Holley EFI system is another thing our builds differ on. One thing I regret about the Holley is the cost. They have so many add-ons that are needed even for basic builds that the cost gets out of hand fast. Even after all this, when I go turbo I'll have to spend even more money on boost control solenoids and maybe a new ECU as the one I have has only 4 inputs and 4 outputs. The budget EFI systems out there are really the future. It will get harder to justify a $500 carb when you can have efi for $850. My friend has an MSD atomic system on his 351w and it runs awesome. You answer some questions and set a few things and you are done. It fires right up every time. Its downside is the lack of datalogging, and no ability to add on gauges or a larger screen. As for my car I might have skipped over the bad parts during the video but there's holes in places. One of these days I'll make a decision but for now it will be cool smoking people in a beat up old Buick haha.
