Boomba Racing Intake Manifold and Throttle Body Spacers

If you like a long service life from your main bearings do not substitute an aluminum pulley for the harmonic balancer.

I agree, I don't see a problem with the changing the weight of the accessory pulleys so much. But IF the crank pulley is a harmonic damper it's not just dead weight it serves a purpose.

I don't believe that it is on the EBM.

Our pulley design retains the crank position sprocket. We've had our pulleys on our Focus ST for over 20,000 miles with no negative effects.

20k miles is not a 'long service life' and I'm assuming you have not pulled the pan to check the mains anyhow, so how would you really know?

There are also other vehicles running the same pulleys with over 80k of use. Those are on Focus STs though.

We'll discuss the EcoBoost Mustang pulleys when we get to it, no need to speculate about what "can and can't" happen.

Boom. Done.

Thanks Boomba for the development of products and for sharing dyno graphs! So, As a person who normally shifts between 3-3.5k, I would be sacrificing a bit of hp and tq, in the rpm range I'd spend a majority of my time in. Darn it, classic case of cant have youre cake and eat it too.

I actually like the comparison of the average gains a lot, shows that overall there is a good increase in power, and it looks as if the lower and top ends aren't affected in a negative way at all, so you wouldn't be missing out on anything, only getting the benefits in the mid range. It would be interesting to see this with other mods to see how they react to the change in intake length.

It would be interesting to see this comparison done by another vendor to see if this is bs or not. If this is accurate then it is a pretty kick ass mod

We welcome anybody that wants to test it out!

Sorry for the limited color availability! All will be back in stock soon!

While you guys were arguing I noticed that the manifold spacer has adapters for nitrous or meth. That'd be a hell of a lot easier than digging into a plastic manifold for a multi port. Debating on whether this or mishimoto's charge pipe set would be a better idea. Obviously there will be a Sig dif in price... Anyone care to weigh in? I'm new to the concept of meth injection.

I've been debating this option for days. I really like the option of having the ports on the TB, but usually, it's best to inject the WM about 6" before the TB. That's the only reason I've held off.

LOL "while we were arguing"

Yes, these come with ports in them for allowing users to utilize aftermarket injection set-ups such as methanol injection. Many users in the ST community have seen positive results from running meth set-ups.

A lot of people like spraying injection set-ups directly through our spacers because you literally have control of which port you are spraying it into and can be sure that it gets distributed evenly. When spraying through charge piping, there is a strong chance the spray can not reach the cylinders in an even manner.

Haha I was hoping that someone would be tickled by that statement.

I was considering the manifold spacer for that direct injection. However, a coworker pointed out to me that only one cylinder would be on intake stroke at a time. So as long as you tune it to spray at the right time injecting behind the throttle body should suffice. After all, I don't plan on using WM to jack up boost. I simply want a cleaner motor since we have DI.

You're also forcing an intake manifold designed to only carry dry air to now carry a 'wet' mixture. There will be a different distribution of wm to each cylinder the way you're proposing based on physics alone. Enough to worry about? That's your call...
