BSD installeddddddd
 

so yesterdayi installed the cosworth balance shaft delete kit i got off focussport.com. idk why i didnt get an oil baffle kit, im an idiot haha

as far as the install it was very very simple. time consuming and VERY messy but it was just a bunch of bolts. once the oil pan was off it took only a matter of minutes to get the balance shaft off. that bitch is so heavy its ridiculous! overall tho anyne scared to open the engine up dont be. this is the first car ive ever worked out and it was a breeze. i have a good time doing it and felt very accomplished after haha i even ate a cookie!

as far as impressions go....no added vides at all, for some reason i feel like its alot smoother. could just be me tho.... as far as sped which is all anyone wants to know, the car feels different. the power band seems alot smoother. i did a pull in second gear, and at about 5k the car felt like i hit boost a second time and i got thrown back in my seat, so i can say up top u feel it. which is what i think should be expected.

overall i say do it,its only $40 not that hard to install and it gives me a piece of mind cuz i kno there was speculation this could have something to do with throwing rods, regardless of if thats true or not (most likely not) im glad i did it!

sweeeeet. im def doing this next oil change

I will be doing with my next oil change as well. as well as a spin on conversion, I'm so sick of that damn cartridge filter.

Good to hear about the no-vibes comment ... keep us posted after a few days of driving. The vibes are the only thing keeping me from doing it ... would have done it already if I could put it back on but there's no going back as I understand it.

cool

talk about a messy job...spin on conversion...

same here,i might as well knock out both things at once so i dont have to do them later.im prepared to get really messy lol.

Yep, that's what I said too haha.

I'm planning on getting oil all over me, Car will be on a lift or over a pit, either way, I will more than likely have oil in my hair.

self-fulfilling prophecy - that is probably mostly in your head.... the power "gain" certainly isn't what I would call noticeable. it's more the characteristics and "feel" that change (other than the benefits of more oil, removing ALL of the old oil, etc.)

all that being said, I'm a huge fan of this mod, I just think this was a little exagerrated here.

i dont notice much difference in vibes either. i will say I think there is a little more...but about the same as adding a moderate rear mount like the SU one or something. Nothing major and it does not bother me at all

How come some ppl were initially saying that the vibes got a lot worse? It's not that I don't trust you guys, it's just confusing when you hear all this subjective info. For perspective... I have the TRZ poly rear mount and did notice considerable vibes. I don't mind them at all, but they are there. How is it compared to that?

if you're OK with the trz poly you'll be fine with BSD delete I think. but like you said its SUBJECTIVE

You are removing rotating mass so maybe it's like installing lighter wheels or a lighter flywheel - the car feels lighter.

Is there any downside to taking away "balance" to the motor? I'm thinking there's gotta be long term negative effects from this mod.

i wanna do this so i can use honda filters. im an acura tech so i can just steal them heheheh
i know they will work b/c aftermarket filters for hondas and mazda have the same part number, as well as some nissans too.

It's not balancing the engine at all. It's sole purpose is to reduce NVH by counteracting the engine vibrations. If anything, it might be worse for the engines having them on.

There's another thread floating around here with pro's and con's.. can't find it right now.

The assembly is heavy but I don't think the actual rotating weight being removed is very significant. You can't calculate the weight of the whole assembly as what the engine has to spend energy on to rotate.

As posted above, One huge plus is An extra quart+ of oil... almost like getting a dry sump install out of removing this, I know not really but sorda.

And the bonus of not having however much dirty oil left, after every oil change.

I'm sure there is a difference in vibes from car to car.. mine in particular was noticeable around 3k. I don't know that I feel comfortable recommending this mod to anyone though.. there really is no way for me to substantiate benefits over possible negatives.. I have no idea if the increased vibes will cause an issue down the road. Personally, I would really caution someone to think about the BSD for a while before doing it if this is your primary means of transportation. at least once you cut the gear off of the crankshaft... reversal will be difficult to say the least.

i really noticed a big difference with vibes, and everybody who drives my car does too. its not as bad as i maybe made out as first, and definitely improves as the car warms up. my internals are heavier than stock, could that make a difference?

anyway... everybody saying the vibes arent noticeable are making me question myself. i notice the vibes the worst when im coasting or engine braking and the car decelerates in the 3000rpm range. accelerating there its noticeable.... decelerating the whole car, exhaust, and steering wheel has a reverb. i dont like when i can see my steering wheel visibly vibrate. to me thats alot of vibes.

anyhow... dont mind my stupid impressions. it appears its my car alone.

no i totally understand what youre sayin, with every mod u have this idea of how its gonna feel and u make it happen in your head to an extent and regardless of what other factors mightve made that certain "pull" good ur gonna link it to your mod.

i do feel a diffrence tho, not huge but i feel it.

as far as vibes i dont feel a single thing. might just be my car idk, the exhaust note is a little deeper tho. def worth it in my opinion and for the price cant beat it.

I felt a very noticeable increase in vibes when I did the BSD. I'm sure my poly TRZ rear MM, PTP trani MM and passenger side torque damper helped pass the vibes right into the cabin and steering wheel.

I feel some increased vibes, I'd compare it to swapping a motor mount.

How much oil are y'all putting in now?
When I removed it, I put around 7qts in.

Thx for all the impressions guys ... the vibes are a no-go for me, so the BS stays on.

yep that's right where I'm at too

agree with alanms6. 7 quarts also

randy, mine vibs like a women waiting for a huge cock. no worries friend.

I installed mine at the same time as MS6 Alan and I got zero vibes from it. If i hadn't sat in his car and experienced the increased vibrations he got firsthand, I'd say everyone who says they got more vibes were crazy. It really seems to be hit or miss.

So does anyone have a BS Delete with an SU 62 Durometer MM? Please describe it at idle and under load at low RPMs.

I had the TRZ Poly and had to remove it due to the very high NVH and do not wish to get close to that level of vibs again...

i have the trz poly and bsd. like ive said i havent noticed any change in nvh. the exhaust seems a lil deeper, more drone i guess, but thats it

I have that MM.

Did you notice any NVH change with the addition of the BSD?

Edit, just saw your earlier post...

What durometer MM did Alan have (his sig just says AWR MM)?

I wonder if the SU62, which is a relatively tame MM, dampens most of the additional BSD NVH and a harsher MM might transmit it to the cabin...or if it is just a crap shoot car to car...

Tks

I think the AWR MS6 mount is 88 duro. I'm not sure how comparable mounts are across platforms, and I think it's a crap shoot car to car anyway. I didn't notice increased NVH from a BSD installed in a speed 3 with a TRZ delrin mount, either.

How do you get this off?

Dremel.

definitely doing this mod.
