Message: <blockquote data-quote="MetaruBZG" data-source="post: 3349234" data-attributes="member: 21264">As far as i know, the silvertop and blacktop are almost identical. Advantages and disadvantages are really up to how look at it and use it, they're both superb engines btw<img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> However, common differences are:- Silvertop/Svt uses AFM (Airflow meter, flap type) while Blacktop/BT uses MAP Sensor (or vacum sensor).- Svt internals are thicker (n a bit heavier) then BT, which is lightened.- Intakes inlets n exhausts outlets on the BT heads are bigger compared to Svt.- Both comes with VVT (intake side only). Svt compression is 10.5:1 while BT is 11:1- Svt pumps out 160hp @ 7500rpm (62 Nm @ 5200rpm of torque), the Bt on the other handgenerates 170 hp @ 7800 rpm w (162 Nm @ 5200 rpm of torque).If your planning to go for turbocharging or any force induction upgrade in the future, the Svt is better due to it's thicker internal/moving parts. The BT is better suited for NA tuning.* If i made any mistakes above feel free to correct it<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1425" alt=":smile:" title="Smile    :smile:" loading="lazy" data-shortname=":smile:" />To me i find the Svt's AFM is a hinderance to upgrade my air filter and uses up space (also cant use velocity stacks or trumpets since u need the AFM to run the engine. The BT on the otherhand, i find that the thin internals are a bit to small for my taste.</blockquote>
