Click here to view the full version : GH billet cooling head for .21 mgt engine in
I was at the GH warehosue last night and they just got a shipment of their new added cooling CNC billet aluminum (i think it's 7075) head for the TT .21 mgt engine! I will post a pic later of it. Looks pretty cool much like their other heads made to fit the TT .21 engine. It's blue in colour on the upper rim.
Yeah but it probably looks like the same heads they make for the TMaxx and Savage. I put the Associated Factory Team head on mine. I dig the swirl cut that it has and it adds an extra cooling fin.
To tell you the truth stock one seems fine unless you hit it. Cooling seems spot-on without over cooling. I think I'd get the factory team if changing tho.
My apologies I took so long. I posted three shots of the head in the image gallery. A side by side comparison with the stock head in side view and top view. A side shot of it mounted on the engine. It is lighter than the stock head. Same diameter and I measured 12mm taller. Lots of surface area with many air ways for added cooling vs the stock head.
I put it on last night @ 3AM pst the pics are being moderated. Hopefully, we'll see'em soon.
