Review:

I swapped out the octane bpipe chamber (size between a limited and mod) and made no other changes to water routing, head pipe screws, 2mm stinger, FCV, etc

Chamber runs sizzling hot and the headpipe is cool/warm to the touch.


Ski has noticeably more power with the tnt chamber and when doing a high speed run it doesn't sign off. Feels like it wants to just keep pulling. Great throttle response, and predictable power band. I figured it would be a little better then a bpipe and was surprised by how much better it is. After I try different water routing and adjust the screws in different combos I will post back with updates.

What results did you end up with? Just curious as I'm running a c4 chamber which is pretty much a copy of this one

the c4 chamber is a little different than the actual tnt. ive had both. currently running the tnt. its a thicker grade of stainless so the quality is a little better. biggest difference ive noticed was stinger diameter. the c4 (atleast mine did) has a 2.5 in stinger where as the tnt has a 2 1/8 inch stinger. the c4 was a little better off the bottom than the tnt and i think this is due to stinger diameter differences but the tnt makes more power midrange and definitely up top.

I had two of the first batches on the c4 chamber it was a great chamber I had a difficult time choosing between the blaster limited and c4. The c4 is at best a rough copy of tnt’s original chamber.

do you know what run on the chambers you purchased? Early c4 chamber had a rounded point and the later version had a flat point.

I purchased it 2nd hand I believe it has a rounded cap.
