I received my Hyper 7, HPI F4.6 engine and my new exhaust today

I have brought a new set of piston & liner and a complete clutch set with 17t bell

I will be running the engine in the hyper, it has a 46t spur gear fitted.

Will the 17t bell work well with this spur gear or what bell would be best to run with the spur gear

Any idea which hyper i have

Too me it looks like a hyper 7. I could be wrong. But it certainly looks like a hyper 7. Second I know the 4.7 is a .28 should fit on the stock motor mount. I know that my hyper 7 has a 14t CB and a 47t spur on the center diff. And they mesh perfectly. That exhaust should fit. Just a heads up you might get a lot of back pressure with the .21 exhaust. I know when I put the axial .28rr in my revo I had a huge problem with the .21 exhaust back pressure. If you drill out the stinger a little bigger that should correct the back pressure issue.

I found out that it is a Hyper TQ Sport
Once i get my new piston & liner, i will try it with the 17t bell, i have all sorts of bells to try.
I will buy a new exhaust for the HPI

Thanks
