Slap it on a dyno and find out.

 

What does that have to do with it hehe..

 

Everyone knows that red is the fastest color so if that is the case he should be good for a good 15-20 horse right there.

 

I would say about 265 hp.
just a guess.

Haha.. oh yeah, i forgot hehe.. nah, his car's black..

damn my car's only silver.. what do u rate my car at?

 

doubt it

 

you guys the horsepower i have is 290, got it confirmed from a rotary expert, 15 from the down pipe and 20 from the midpipe, and black is the best color for an fd beats red and silver.

 

You should definitely have more than 265hp. The stock muffler is a piece of ****, you might want to upgrade it. Also, don't forget to upgrade your ECU too.

 

You could have 160 hp because the previous owner treated it like ****, but since your previous CRX SI had only 115 hp you can't tell the difference because this car just feels so much faster to you because you may have never ridden in a fast car -- TAKE IT TO A DYNO BUDDY -- anything else is pure guessing, since nobody knows what state of tune your car is in, even if it feels "fine" to you .... unless you have owned an Rx7 for a long period of time, and know exactly what it should feel like at the different upgrade stages.

 

W.r.t. the white color, there was a white rx7 in winnipeg that went out to BC. It was ragged on pretty bad but its only mods were MP, but it also had CB that the guy was getting rid of.

Just curious. but you are right black is the fastest color, especially with yellow stickers.

Ditto. Don't even upgrade your CB until you get an ECU.

It's hard to say what your HP is since you have the abnormal setup of no cats and the stock CB, but you will probably be anywhere between 280-290hp
