how much horsepower are you getting out of your NA?
I was just wondering what type of horsepower other people are getting out of their NA, along with the setup they are using? Right now I'm clueless as to how much horse I have? My car is setup with bonez highflow cat, dynomax high fow exhaust with 2.5 in pipes, k&n filter charger, and racing beat header. Does anybody have any idea as to how much I'm pushing out?

BonsaiRX7 who you talkin' to. That's not my car, its one of the ones from the gallery. I chose it because it looks a lot like my car, just not turbo. Welcome to the boards!
Not enough!!! I know what your talking about. heheh

I also have similar mods. I have gutted cats, pacesetter headers, ractive mufflers, and K&N air filter with cold air box. I also dont know how much HP i have, but I am hoping on buying a GTech Pro to play with.

rxseven full exhaust will only net me 146 stock hp levels. Wow I must have been at 70hp before the mods. I think thats just a little low! 175 flywheel doesn't seem far fetched. Sorry but you will have a hard time convincing me otherwise.

Ya ok Im running close to stock HP. I think not. A stock RX-7 must be REALLY fast compared to the cars Ive beaten i.e. Civic Si, Eclipse RS w/full exhaust, Eclipse V6, and a few others. I dont think that the mileage has that much to do with it.

Read this thread. He's putting out atleast 175hp probably a little more. My mods are very similiar except for 89+ intake manifold. Which is probably why he makes a little more. Let me remind you I am not saying 175 to the ground only at the flywheel. 175 give or take 5 is very realistic.
Let me ask you, whats your estimate?

Throttle body mod, do a search if your really interested in doing it. There's probably a couple of write ups. Not really ignorant, its a board where you ask questions. Now you know

Not knowing the condition of your engine. IE compression, milage etc, IT is hard to say. Remember a lot of the NA's on this forum are at 100K+. There is a lot of variables that are unknown. The only way to know is to put it on the dyno. Comparing your mods to someone elses is like saying you can beat a ferrai 'cause your buddy raced you who raced a vette that beat a fererrai.(sp, I'm lazy 2nite)
175 IS possible, but to say you are making it without a DYNO sheet to prove it is ludicrous!

Well then this whole damm thread is worthless because grande wanted an idea of what he is running. I gave him an idea! When I purchased my 944 turbo I didn't need to dyno it because Porsches test is probably pretty acurate, therefore 217hp + or - 15 is what it's putting out. It's just an estimate a very reasonaable one. And comparing my mods to Silver88gxl I think is fairly close unless I blew an apex seal on the way home from work.
Just an estimate I am not saying for sure. You are right without kkowing the condition of his engine I can't really talk, but I know the conndition of mine.

I recently have had my car on a dyno, but dont have the sheet transfered to the pc yet. But I have a 91 n/a, with RB header, presilencer, and cat back. Apexi cone intake, and a custom built cold air box. The car has over 144K on it, its still the original motor, i turned out 116 hp at the RW. I thought it was low myself, but considering the age of the car and the milage, ive been told that is average.

Thank you Jason. An estimate is one thing. A dyno is proof.
I know what my engine builder quoted for HP, until I go to the dyno and verify, I can't say. If the number is lower by ~10%, the engine builder and I will be having a long lengthy discussion why!

Before I put my REW motor in I dynoed my with my N/A engine. I got 138 rwhp and 114 ft/lb's of torque. This was with a year old (about 8k miles) engine, monza headers, bonez main cat, RB catback, K&N cone filter and operational 6-port actuators. He he....I'm happy to have doubled that now

Matlock, I am just being realistic here. An older car with average compression, older clutch, loose tolerances in the tranny and rear end is going to affect torque transmission quite a bit. I deal with power transmission products on a daily basis so I know a little about this.
But really no point speculating about it all. Until you go to the dyno you can't be sure so you might as well think you are making a lot of power, atleast that way you justify spending big bucks on your FC. But I have noticed quite a few N/A people on this forum being dissappointed by their numbers.

Maybe I should just reword stuff. Hypothetically 175 with exhaust is possible. I guess it would be foolish to think 175 on a tired clutch and drivetrain. I have taken pains taking care of my car and every car is different. I gave an estimate and it was probably a little high. With drivetrain loss most probably put out 160 flywheel, with full exhaust and intake.
It all really depends on the care, the car, the compression, the dyno, the temp, the list goes on.
I admit my mistake. My estimate was a little high.

Around 5k not including my PFC and the TII drivetrain. Then some other misc BS. But about 5k to get it in and running. I sourced many parts used and peiced stuff together to get it running. It's no show install or anything...but it runs like hell. I did it all by myself btw...so you can throw in a hell of a lot of labor on top of that.

That's awsome! I have thought seriously about a 13b-re swap, but decided to save. By running like hell I assume really good correct? 5k way lower than I expected. I would definatley have done the myself too. That would be fun as hell.

Well. I've still got more work to do on it. And yes I meant it runs good. I did 13.3 before I got my PFC and haven't really raced since. And 5k is strictly for the engine to run....not really run great. The Intercooler and especially the piping is shody. The radiator really needs to be upgraded but it does it's job okay. I'm in a relatively cool climate. I got a lot of parts for free or close to it from a friend of mine who had a wrecked TII. So you could end up spending close to 7k or more and that's if you're doing it yourself. Better get some good wiring skills.
