BSD gains and potential problems?

I saw a blog from a couple years back about people not having any problems with the balance shaft delete, but was just wondering if people have been running the BSD without any problems.

Also, I've heard a wide range of people claiming what the gains are. I've heard from a small change in throttle response to 7 whp gain. Can someone with first hand experience tell me what their gains were

We did the Bds mod with the intention of being able to place a windage tray in the oil pan. We have notice a slight vibration at idle, but after that no issue at all. My car is a dedicated race car, solid motor mounts, super high rate springs, and full race suspension struts and shocks. Prior dyno results and post results were more influenced by the tune than the Bds upgrade. Is it worth it, for our application it was a must, for a street car with small mods, if ya like working on your car go for it.

Its an easy and cheap way to remove 20lbs from the front of the engine. Been balance shaft free for almost a decade, and love it.

Same here, dumping that lump of iron was a real improvement - weight off the nose & the engine spins up easier (noticeably quicker change in revs).

Vibration change on stock mounts virtually unnoticeable - from 0 to "I think I can feel it running" at times....

Extra quart of oil capacity doesn't hurt either.

So the added vibration wasn't a big problem?

With stock mounts you probably won't notice a big difference. Perhaps a little bit of vibration but nothing crazy. That being said, this is also a subjective subject. If you put polyurethane mounts in you will feel it even more. I had the BSD in my ST for years with the rear mount and trans mount being polyurethane and loved it. In my experience putting a polyurethane passenger mount in made the vibrations really bad but with only the others it was fine.

Ability to run a baffle, extra quart of oil, faster spin up, minimal vibrations, all sounds like a win win.

Yea, it all sounds like an awesome piece for $40. Also would it hurt at all if you didn't put the full 6 quarts in? Like say you kept it at 5

All the above^^^^^^^^^^^^^^^^ win, win, win. I've had no issues w/ a bsd plug & a windage tray. I just installed a vf engineering trans mount w/ no vibe issues. Your removing about 18 lbs of static weight & don't forget the rotating weight too. Your motor will spin up quicker & hold more oil & you'll lose weight too. Its one of the best cheapest mods you can do.

Do I have to get a new oil pan or something?

No new oil pan required, and that extra quart is needed to get the level up to normal without that large assembly taking up space in the pan.

The BSD delete kit by itself just blocks off the oil passage for the balance shafts. Just pulling the assembly would leave an open oil passage right to the pan & you'd lose oil pressure.
