250 HP Non Turbo.. is it possible?
 

discussing this among friends and figured i'd throw it out to the community.. is it possible?

yes.

possible? yes. streetable? no.

Racing Beat claims their 51mm Weber carb kit can do 280+ hp on a rotary... but I cannot imagine that the low-end drivability is very good. They also have a progressive Holley 4bbl kit that looks like it would function better over a wider range of driving conditions, but they do not list the horsepower obtained...

Just to clear up a common misconception, the horsepower ratings are the amount of fuel and air that the carb kits can supply, not the amount of power that you will get by bolting them on a stock engine. The engine still requires a lot of modifications to reach those goals.

This is the Racing Beat application guide for their carb kits:

Fuel injection is always superior, of course.

That is gonna be a peripheral-port. You can't drive that on the street unless you never see a cop ever.

Agreed. Their website seems to imply that those numbers are what you could expect on a highly modified engine at 10,000 rpm or more.

just add an extra rotor

yea you can hit 250rwhp, with a full j bridge, IDA's, a stand alone, overhauled fuel system...so no so no so no, why do people keeps asking these questions?

+1 to post count i think...lol

Still not 250. And that was with a 13B-RE and custom exhaust tuning

Sheit son... All you need is a BIG bottle o' NOS. Actually, make that two of them. And you will need them tonight.

why 250 why not 249hp jk well what engine do u have is it a s4 or s5 engine block?

I'm going with j-rat. Nitrous is going to be the cheapest/easiest way

REW or RE block full bridgeported with S5 NA rotors and a downdraft 48 Weber or a Jaytech intake with a 650 double pump holley mechanical secondaries.

Will overnight parts from japan help make 250hp?

not if he gets a motec system exhaust and in those 10 seconds less he free lol


but back to the topic what are you going to use the car for track? drag? drift? or daily cruiser? to tell you the truth your better of getting a turbo 2 engine for your FC and make easy power then trying to squeez power out of n/a while trying to avoid cops

These past few comments really make me love the RX-7 community =]

some quotes are just timeless...lolz

I was just about to do what you just did... link that thread.

I have driven that car, low end torque is fine, as you can see in the dyno graphs. Actually, its very fun to drive around town. And its completely streetable.

Maybe. Maybe not. But he'll run 9s.

not if torreto shows up :lol:

In that 2jz fd ROFL

Don't forget to double clutch

Yeah. It sucks to blow the welds on the intake then you gotta go replace those piston rings.

Hey, don't trash talk the piston rings yo.

I'm a >250 whp non turbo.
