Smile My thoughts on a Bridge-Port 13b :)

So for the past year (almost), ive been daily driving my FC.

If you've seen my build thread, I think its titled: "My ongoing project car", you know that the 13b I'm running has every single port ported, some of them quite extensively, including bridge-ports on the end-irons.

Basically I'm going to praise this engine here.

But first, yes there are drawbacks.
Bad gas mileage, mine gets 13mpg.
Tricky low end, driving with rpms under 2,500 = just no. Unless your experienced with this sort of thing.
Louder than normal exhaust tone.

Now i don't have much experience with other rotary engines as to compare performance, except an N/A 13b.
But I'm going to say this, there are 2 things:

#1. The noise it makes at idle, just one of the best sounds in automotive history.
#2. When you get on it, and the rpms rocket and go past 5k, the engine sounds like some raging beast right outta hell.

These two things make the whole bridge-port thing Totally worth it.

I swear it puts a big smile on my face, there's a laugh included on there too.
