AMS Performance

Hello everyone,

The AMS BBTB for the M112 engine is finally complete. Sorry for the delay but some finishing touches had to be done to the BBTB to make sure it was as close to perfect as we could make it. We went to great lengths for this big bore throttle body and we feel it will be a great addition to the M112 performance lineup. Benefits include more HP & TQ and improved engine sound as well. Greater benefits will be realized on more highly modded vehicles. We recommend doing BBTB if you have basic performance upgrades already on your vehicle. Specs:

Bore: 74mm (18% more surface area)
Plate: Mirror Polished & engraved
Price: $299 + $100 core (but discount available if purchased in addition to our M112 pulley)

And without further ado:

And for the record we will try to make an 80MM one for the C32 guys but that will take longer since we will have to machine the entire housing out of solid billet (quite a task to say the least).

What are the hp gains?

AMS Performance

on avg roughly 5-8HP but if the car is highly modded then you could see 10+ at high rpms (post peak HP). Throttle response is greatly improved as well as engine noise greatly improved. It works very well with intake & exhaust mods (especially if you have headers)

hmmm me likey!

Hey guys,

believe me, our company is getting bombarded with requests for new products and we are trying our best to keep up with demand. We will try and come up with a totally new approach for the C32 & C55 BBTBs b/c the current options on the market place just aren't cutting it. In order to do a true 80mm TB that fits well we will have to machine the cores out of solid billet (which needless to say is very time & $$ intensive but it will produce much better results). This will allow for a much stronger thicker wall while still maintaining a true 80mm straight bore and the overall housing size will be as compact if not more compact than the current design. We will keep everyone informed on all our new updates.

Hello Everyone,

Just wanted to let everyone know we have a few BBTBs in stock and are incorporating them into our Stage 1.5 performance package. When purchased with our performance crank pulley you will save an additional $50 as well as saving on combined shipping costs.

Thanks

dont forget about m271's... any plans for us?

AMS Performance

We are working on it, lots of new prototypes coming out. I will reveal more info when I have it.

have 06 c350 6MT--- m272, please pm me info ie , dyno sheets and any testimonials on crank pulley and throttle body, your website does not address pulley for the m272 specifically, ,, i already have a ecu tune , greens, rez delete,

AMS Performance

Hello,

The M272s already have larger TBs, the only thing you have to do on the M272s is upgraded performance crank pulley. You have PM. Thanks

AMS wants to know what most M112 owners would prefer. Would you rather want a polished plate or an annodized plate (of a specific color). I thought I would ask to see what would be the preferred look overall amongst most M112 owners. Thanks for any input.
