The reason why I ask this question is because I cannot afford both. I was curious which one (s) would benefit me more. The fidanza 8lb flywheel or an aftermarket fuel rail and fuel pressure regulator? Im either going to sell the flywheel which I was supposed to sell before earlier or get it installed....Which do you think would offer me the most performance? According to ebay which I assume is not accurate that a after market fuel rail and fuel pressure regulator will give me 12+ hp. As for the flywheel im not sure which is why im asking.....Thank you in advance....

 

just adding a fuel rail and fuel pressure regulator wud just add more fuel in ur engine, so unless u have other mods and tune ur a/f raito u'll just be making ur engine run rich...depending on ur mods and if u have the tools needed and/or ability to tune ur a/f ratio, i wud go with the flywheel, though 8 lbs is a common weight for flywheels dat i have sen around HT it seems a lil light to me

 

So what exactly are you trying to say? Do you mean that no matter which I decide to go with I'll have to tune my air/fuel mixture?

 

uhh, no you wont have to adjust your air fuel ratio for a flywheel...but what he was trying to explain was that simply adding a fuel regulator and/or fuel rail would not benefit a stock motor. when you add fuel to a motor you also must add air to get a correct balance. on a stock motor fuel pressure turned up will yeild no benefits.. it will look fancy but in the long run might give you more problems than you need.
i would suggest getting a flywheel as you will actually "feel" the results though acceleration, decel, etc.

How much power do you think I could expect out of one as far as hp wise? According to tasutoparts.com they said you expect any where from 10-30 on a 8lb flywheel. Im a bit skeptical about that piece of information.....

they are gonna tell you what you want to hear. there is no way to really know for sure until you put it on your car and dyno it. as far as performance goes, of your two options, only the flywheel will make your car go faster

 

you also have the wrong mentality. a fuel rail is not something you can simply slap on and get more power out of. it is part of a whole bunch of parts, and that group of parts together will make your car go faster.....to make it simple

 

A lightened flywheel does not give you more horsepower. It basically just reduces the amount of mass that the engine has to turn... Acceleration and deceleration DO improve, but not b/c of an increase in power.

 

wouldn't it give you more power to the wheels??

 

no, you would just get it faster...

not sure on this, but probably, maybe just like a horse power or 3...only becuase its lyter and less power is lost thru the drivetrain

 

theoretically, a lightened flywheel would show power improvements on a dyno, but it's not necessarily adding power per say, it's merely reducing the amount of power lost through your original flywheel...but you should see a gain on the dyno...

 

unless u need to change ur clutch/flywheel it is a huge waste of money just to get a lightened flywheel installed, with the f22 motor after ur i/h/e uve pretty much run out of options, unless u do major expensive work ur not going to be getting much power out of it n/a, your best options are either start saving for FI or nitrous, otherwise u will be spending $200 on pullies for maybe 1whp, $150 for crank pulley for maybe 1-2whp, n/a cams for f22 forget about it, $1k for headwork for maybe 10whp, n/a f series just isnt worth it for most people....

 

So basically what your trying to say is that there are no other bolt on to my car than what I have that are hp worthy other than getting nitrous or a turbo? If thats the case I'll probably just save up for an engine swap....

yes, that is basically what he is saying...if you feel you have the knowledge to handle a motor swap i would say that would be a good plan, there is also the forced induction route for the f22 though...it just depends what you would rather do.

 

i personally wud choose turbo instead of a swap

not an increase in power, but feels like an increase in power.

more * per $ with turbo.

In a very good nutshell

Usually people add a fuel pres reg after they increase the airflow through the engine. Because if you just make the engine breath harder, it may run lean, consiquently you will want to add more fuel. But just adding fuel press alone will make it run rich.

You can do bolt ons for some added kick. You don't totally NEED to do a swap or FI.
