N/A vs. F/I
 

I'm still new to the forums and need some help with this topic. I'm confused about why some people stay N/A. Is there any advantages that N/A has over F/I? I don't see how there could be but like I said I'm still new. Also how much horsepower can you get from the 4.6 when staying N/A?

Depends what kind of motor were talking about.

some people would rather spend 100-400 dollar bursts on bolt ons. Rather than 2 grand at once on a supercharger. Then you have to worry about getting it on, and getting tuned, plus in some cases your risking reliability.

But i think money is the big issue for some people, tbh im in college as a full time student, i worked full time all summer last year and was able to buy my supercharger, all the supporting mods, and pay a shop to install it and tune it. So it can be done, in another thread i mentioned i bought all the parts i needed in a 3-4 month span.

4.6L 2v SOHC

on a 2v its many ppls opinion that staying n/a will cost Alot more in th longrun vs going with a blower trying to get decent numbers n/a. read over these two links on th subjects. one na vs fi and th other is fi cost

Congrats on the buy. I'm also in collage and I know how hard it can be to spend all that money in one place. Just let me ask you one thing. After all that work and spending all your hard earned money on it. Was it worth it??

an arm and a leg trying to go na and get close to the numbers and possible numbers going fi with a 2v. Some ppl seem to like th "cool factor" i guess on trying th na route on th 2v. IMO the cost just takes all of that cool factor away knowing you could have gotten higher numbers and more room to grow with a blower.

Thanks the links were alot of help.

Lot depends on various factors. Blown engines will put out more power but cost more money.

Are you saying for example that a blower setup like a v1 s trim will cost quite a bit more than trick flow heads with decent cams,intake, and exhaust? I may be wrong but trying to go na on a 2v and get close to blower numbers na will cost quite a bit more

Some guys aren't bent on MAXIMUM power output. On one hand, having a ton of power on tap would be cool sometimes. On the other hand, I'm kind of an old school guy, so I find it cool that I have run 12.5 NA in my car without touching my heads (and not using a clutch abusing launch). My DD is NA(~285rwhp), and I utilize nitrous(417rwhp) for passes at the track now. My NA motor should last a long time. A boosted 2V may see shortened life from higher stress levels.

I get your point. Im considereing the n/a route with my tbird with th npi 4.6 http://www.moddedmustangs.com/forums...ercharged.html

as long as you have a reputable tune and arent seeing 12+psi everytime you push the pedal that motor will last you a long time

agreed!

Agreed.
A blower set-up does not necessarily mean a shorter engine life. A safe tune is real important, moderate power levels and not ripping the car everywhere you go would provide good longevity.

The absence of these items will tend to stress the motor more heavily.

N/A 2V=BIG $$$$ and "I" think N/A definitely has ALOT of cool factor.

But.... F/I will definitely make more power for a lot less $$$. As far as cool factor... "I" think anyone can bolt a blower on......hahaha

just as almost Anyone can bolt on a blower almost Anyone can bolt on some heads/cam and an intake both will require tuning. If the 2v responded to heads/cams and intake like a coyote motor or ls motor then maybe it would be more common but sadly that isnt the case:icon_banana:

personally i think it was, it just puts the biggest grin on my face every time i get on it. I remember first coming on this forum, and every person would say that bolt ons are useless and to just go f/i. I didnt really get into bolt ons too much and im really happy that i did the supercharger build

What supercharger did you go with?

its all over his sig discription and pic. Vortech V2 S-Trim

Some people just prefer to take care of the little things first. The boltons aregoing to allow your motor to breath better which will only help with the blower. I personally put in all the suspension i needed and got a good set of track tires and a built rear with 4.10s as well. Theres nothing that makes me laugh more than a guy showing up at the track with a blown car that is running mid to low 13s cuz he hasnt done the right things to make it hook, while im going 12s with a bolton car.

it all depends on what your goal is with your car. when i bought my car it was bone stock and i wanted to some day have it over 500rwhp, so i started with all of the bolt ons, then i built my motor, with blower cams because i knew someday i'd have a s/c, and i just bought my supercharger setup (had the car almost 6 years now), but it's going to pay off in the long end. if you want quick numbers, go with the forced induction, but if you plan on keeping the car and going big with it, stay n/a, build your motor, get your bolt ons, then when you do put a s/c or turbo on it, you'll get much more out of it. just FYI, my car with a forged 302 stroker, 10.5:1 compression, stage 2 heads, stage 2 cams, full exhaust, i put down 331rwhp and 368rwtq, but it cost enough money to buy a couple superchargers to do it lol.

In the debate between N/A vs F/I, I say take the best of both worlds and grab a bottle of boosty juice, that way you can have the everyday drivability of a N/A car and still be able to have the smile inducing power of an F/I car.

A centrifugal blower car is VERY STREETABLE. The power doesn't kick in until 2500-3000rpms. The average driver does right around 3000rpms give or take so around town it's totally fine. I can tell you because I have one.

+1 I love n/a motors like the new boss 302 motor spinning to 8k is just sick, but at the same time a I think a Tork tech 2v is sweet too lol ( I compared apples to oranges I know) it just depends on what you like and what your budget is

Spot on!!!

If the 2v had the output stock of the 5.0 or boss it would be a bad ass n/a ride and if it responded to bolt ons like those motors did to that would also be bad ass. But we all know in comparison how the 2v responds to bolt ons or how much it can cost going the na route and the gains you get from it.

Thanks to everyone. I have gotten a lot of information out of this.
