ok so for all the people out there that told me i couldnt get over 300 to the wheels while staying naturally aspirated your retarded. Because i'm doing it right now. Fuji Racing is building me a motor with some ITB's on it and i should be accomplishihng this within the next few months. CANT WAIT!!!


But one question. Who has had good experience with different injectors? what has been the best??

hope your going peripheral ported :P

I hope its atleast a 20b with p-ports otherwise its going to be very hard and a money pit.

a 13b with p-port and other mods can hit 250+

to the OP, how are you gonna make a claim when you don't even have anything to prove your numbers yet? congratulations on your project build, but focus on it first, then brag if thats your kinda thing.

but who am I to tell someone how to live? just my $0.02 cents.

get the car dyno'd before you start calling people retards.

you will not make over 300whp n/a on a 2 rotor engine.

if you are going with a peri have fun driving that on the street...

lonewolfrx

300rwhp na? the motor isnt even finished yet. ill believe it whens it built, running, and you have a dyno sheet to prove it.

it already somewhat hard to hit 200rwhp on a non ported 2 rotor na motor

-CON-

It's got to be fuel injected PP and the wheels need to be bolted on to the flywheel Then you might get the over 300 number !!

Oh so it must be a v8.

wow cant believe i wasted 3min reading this thread

Why so doubtful, there are many clues is N/A performance section which clearly showing that 300 rwhp is pretty much standard for circuit racing 13B PP and numbers over 350-370+ rwhp are talked about in all motor drag racing...

Nevertheless, to the OP, what will be purpose of this car?? It is well known that large overlap N/A rotaries on the street(PP, BP...), with enough "quiet" exhaust system, (still ungodly loud) don´t have much over 220-250 rwhp-better examples, it can be far worse... but go for it, we will see

-CON-

370 rwhp, N/A ? I'd like to see that !

Liborek

I know, very hard to believe when all over internet is stated "13B PP 300-350 HP"...
But how could you explain all motor 13Bs trapping over 130 MPH, some even 135+ MPH in the 1/4 mile with weight over 2000 pounds?? Its that simple, power is there...

I found these two dyno graphs in archives of N/A performance forum....both 13B PP. As you can see, in first dyno torque peak is 200 lb.ft at around 8000 Rpms. Through intake/exhaust tuning and port timing, we can shift this peak VE% to higher rpms...
So we can have such power, in best scenario, it would take just a bit over 9700 Rpms...but since torque will be tapering down it will be higher in the RPM scale...but probably not beyond 10500 Rpms

If you are interested, search for posts by Crispeed in N/A tuning and all motor drag racing. He is riddle man but you can see many clues whats possible...

because those cars cost more to build than simply bolting a turbo on and making 300WHP easily. those cars cost as much to develop as some of these cars making 600+WHP.

people are doubtful because if we all had $1 for these dumbasses coming in and making claims then we would ALL be rich. making horsepower naturally aspirated isn't an easy task, especially if you don't have a ton of money to throw at your car, as most don't and most also realize you can get more power for less with force fed induction.

Liborek

Of course, I´m fully aware of it but this isn´t point in this discussion. With turbo, we can have totally mismatched combination and still produce resonable power, N/A tuning is trial and error-and this takes money...

As above, I know and we both know what will be outcome of this "project"

Autoxrx788

The reason i dont want to go turbo is because evryone does and I'd like to be a little different. And I autocross so I'm not down with a turbo spooling up in a corner and losing control. So before talking like a bad *** over the Internet remember you don't know my intentions. And learn how to talk to people respecftully you ******* dumbass.

So put in an NA motor that makes power reliably like a 20b or a V8. 302 swaps are cheap.


Ahahahaha. Have you ever driven a turbo car before?

This proves Karack's point exactly. Morons who come in making claims, not backing them up, blah blah, same story every time. Then when they get called out on it this happens.

Evil Aviator

There are several thousand non-turbo RX-7s throughout the world. Nearly 100% of the winning GT RX-7s from the 80-90's were non-turbo. There have been 300hp NA rotary engines available for well over 20 years, which is about as long as many people on this forum have been alive. Sorry, but I don't see anything new or different here.

I don't suppose that the race shop that is taking your money explained to you that your 300hp PP engine is going to drive like crap on a tight autocross course unless you keep the engine revved up like you would with a turbocharged engine? Also, did you even tell them that it was for autocross, which usually has more noise restrictions when it is held in a parking lot as opposed to a race track, and favors a high-torque intake as opposed to a high-hp intake?

I don't suppose you realize that you sound like a "******* dumbass" by bragging about your engine before it is even built?

Why would you ask a bunch of "******* dumbasses" which injectors to use when you have a professional race shop building your engine?

skir2222

I doubt that your goal will be met, 300hp seems like a long shot staying n/a. I don't understand who the retards are but many people would rather go turbo and make the power more easily at a much cheaper cost.

I am going to guess you have never driven a turbo car, you can alter the boost and change the size of your turbo to better suit your needs so you don't loose control in a corner.

Would love to see how this "project'' ends up when its complete.

By calling people ******* dumbasses you will only push people away because thats just completely disrespectful when no one said anything negative to you, there is no reason for it.

listen son, i was as respectful as i possibly could be. if you want respect then you should learn to earn it, and you certainly didn't with this reply.

if you want me to really rip on you then just let me know and we can go all up into your "build", what you do, how much money you earn, how long this "project" is going to take and just what you plan to invest into it and back it up after it is all done with. by the way people autocross turbos all the time, if you learn how to actually drive then "spooling up and losing control" is just something you have to learn in life to control just like when you took your diapers off and used a clutch for the first time.

in short, you came in with the billy badass attitude that "i am gonna prove all you dumbshits wrong" touting, not me.

never once did i say it was impossible either, but for the reasons EA stated i think you don't know what in the **** you are doing and got yourself in way over your head by even putting this thread up and are digging yourself a hole. all i'm seeing is you want to build something to prove yourself, proving yourself is about earning respect and not about proving other people wrong, your motives are all messed up and i might even suggest seeing a therapist about it.

my suggestion is rethink your priorities and what we have hinted towards you in not only what you say but what you are doing. if you want to build a 300WHP n/a then go for it without the attitude and not for stupid reasons such as autocrossing the car(because that's a rediculous scenario) but to be one of the few street driven 300WHP n/a second gens around.

Let me speak from experience....
A PP *at least in the 280rwhp+ side* engine has MORE "turbo lag" with a streetable tranny and final drive due to every shift dropping you out of you're power band. than ANY turbo car i have not only driven but been in besides one space frame not street legal low 8 second car.
I have completely given up on making a lot of hp and am sad by how much others dwell on having x amount of peak power. I have said countless times as of late that peak power will not make you're car fast, average power will. Besides one smart *** that PM'ed me about CVT's no one has been able to give a good argument against that.
I have something in the works now on trying to prove something, I don't have the engine, hell i don't have the car I'm looking to use. There is no thread calling others a dumbass, but I will tell you what you will see..... A fully documented build thread showing what i did and why i did it EVEN IT I FAIL at what I'm trying to do and if I do fail I'll also post why I think I failed and others can learn from it as I would have.
lastly, its kinda hard to get bragging rights if you have some one else do all the work.

Talk cheap (soooo cheap, that's free)!!!! Let see ur motor and ur project!!! Update us often!!
300rwhp on n/a (w/ supporting mode such as suspensions, chasis strengthens etc etc) gonna cost u tons of money and most project that cost tons of money most get parted out before completed!!
(Due to lack of funds). It cost me $15g, to built 300+rwhp turbo car (and it mostly a bolton kits).

Start posting pics on this theread of ur car (project) please!!!

altec_fc3s

What in the... unless you can rev your motor to ungodly RPMs it just isn't happening. If you have to rev your motor to ungodly RPMs this will not be a streetable car..

That jab about turbos spooling up? Here's a link to a Subaru thread where a kid's turbo "spooled up" at 12mph in a mud puddle ... and this was AWD!!!! Of course he's full of ****, and so are you thinking that you cannot drive a turbo car smoothly. It's the driver who ultimately decides how the car handles, not the motor.

So is Jimmy building the engine or is he getting Kilo to build it?

I'd rather have money than be different. Why spend 20k on a 300hp N/A just to be different when a 20b GT2198398124987 Turbo rips past you like nothing with 20k? You'd just end up saying you put 20k in your car and people still don't know wtf you did.

At least with a giant turbo people will give you props, lol.
