My 95 is too slow...

bone stock car u say. so the gear is prob either a 2.73 or 3.08. since its a DD prob dont need to get too crazy. i would think a 3.55 gear would be perfect. noticeable upgrade and still maintain some mileage.

as for the charger: i spoke with a rep from vortech a few months back about putting a s-trim on a stock 94/95 302. he said it would put down high 280's whp on 6-8 psi.

Would this be a decent reliable setup & would it make some decent power??? Would it have better results, driveability, & reliability than a H/C/I setup??? What would I need to tune it???...

IMO if it came down to supercharging the stock motor or doing a H/C/I swap Id go the H/C/I route and 3.55 or 3.73 gears. You will need a dyno tune in order for the supercharger route to really work and to fix any drive ability issues. Unlike a H/C/I set up it will require more to tune it in order to make it run right. Plus you need to upgrade your injectors and your fuel pump. For the amount of money you would have to dump into it in order to supercharge it I dont see it as being worth while compared to the power level you could have w/ a H/C/I set up. Just something to consider.

Hard to beat for the price. A kit like that will give you a good 300 RWHP if not very close. Hard to put together a supercharger, injectors, dyno tune and any other mods for that price as the H/C/I kit. you wont get anymore HP out of a stock 5.0 w/ a supercharger then you will a H/C/I set up or if you do not enough to make it worth while price wise.

which is probably less then a good H/C/I kit set up .

just my the 410 out of my car

I dissagree with the comment about "you will not get anymore HP out of a (stock shortblock) supercharged car than a (stock shortblock) H/C/I car". There are many guys who get over 300rwhp and closer to the 400rwhp mark with a stock longblock. Honestly, around 300rwhp is about the norm for a H/C/I car on the high side without being REALLY purpose built to get more.

A tune is a tune no matter if its going to be to get the charger to work right or the H/C/I to work right so that is a wash. Both can run without one but will prob. run like dog poo.

6-8lbs IMHO is about worthless. Most people you see running a charger will be in the 10-15lb range. I know a guy who put down over 400rwhp with 15lbs on the stock shortblock, factory unported E7s, stock cam, and a cobra intake. You will be VERY hard pressed to hit those numbers on a stock 302 without dumping a lot of money into it. Granted the 400hp level is alittle more developed than avg. but it should not be hard to hit 325-350rwhp with a quality supercharger kit. Those kits often include injectors and fuel pumps so research what you get with the kits. You will have to buy larger injectors with a H/C/I setup also.

If I was looking at a DD to mod...I would be looking at not having to pull heads and install a cam. I would be looking at something I could install without cracking the motor open (maybe a new intake at most) and could be removed with more ease/broght back to stock easier.

Good points by all

I do relate to old school power by just using what mother nature can do

Then again ... forcing the mix is a great way to make power as well

Can't expect 300 or better with either method with no compromises

IMHO ... NA is a bit more forgiving than the forced route

I'd lean to that method for a daily driver
or
If one has little experience with building/owning modded combos

I agree with the thinking that low levels of boost on blown oem combos
yield about the same amount of gain as NA h/c/i combos

Using a large amount of boost on a dd oem combo can be a bit tricky

If going NA on a dd stick combo ... I'd go 373's

Final thoughts would be focused on the fact you talk about a dd

Just be cautious about going too radical in your quest for power

Good Luck with all your decisions

I plan on doing 3.55's soon, & as far as the maf, fuel filter, plugs, cap, rotor, i did that about 6 months ago...

Thanks for all the replys everyone. I will have to give this some thought for a while because as far as doing a h/c/i swap, I am already 1/2 way there, all i need are heads, a cam, & a few odds & ends. No matter what, I am going to have to save some money up for a while to make either or happen. I will keep u guys posted...

Thanks again

sorry man i just had to laugh when u said ur half way there, there is alot more that goes into a CORRECT na combo than h/i/c...and the heads are by far the most expensive

I agree with the above, i too contemplated supercharged or na....

with a supercharger u can have many problems, thrown belts ect..
and u can ruin ur motor if its a little out of tune...
plus on a dd i guarantee the na combo will get better gas mileage..something to think about...
GO N/A

I have a stock 5.0gts dd and i have thought about modding it...and I thought a used s/c kit would be cheap and a hci would be great but Im lazy and think I might swap out my 3.27 for 4.xx....My GTS isnt fast but still handle bolt on Type S RSX's...and old assed Monte SS,Pimpallla SS's..would like beat 4th gen F bodies though..

But I think Gears,Intake,TB, would be what ID reccommen for just a dd...

Listen to this guy, he knows what he is talking about. And yes 3.73's NA.

I don't see why adding a supercharger would give a person problems with throwing belts? I never had a problem with losing belts with my Vortech.

The NA combo will most likely get better gas mileage, but that isn't necessarily a guarantee either. That really depends on the driver.

The lack of a tune on a NA motor can also blow it up.

Personally, the cost of a H/C/I is almost certainly less than that of adding a blower. I look at it like this: I knew I wanted a H/C/I and I knew I wanted a supercharger, I just had to choose what order I wanted to put them on it. I chose the charger because it generally nets more hp/tq than your average H/C/I and it can REALLY amplify future mods.

Just like was said earlier, there are stock blocks who have just swapped intakes making high 300 whp.

Really, both can be dependable with a tune and the right parts. A charger will most likely cost more but will also most likely give you more power.

Do you want a broad torque curve like a H/C/I will give you, the high end power of a centrifugal charger, the low end torque of a roots/screw charger... the choice really should be what you ultimately want out of the car and what you want out of it now.

good points

when i said tune tho i was more referring to the tune up items, spark plugs ect...
but i guess there importtant on both na and sc

YEs, BUT you much more easily do nasty damage on a blown motor outta tune than a H/C/I..

Unfortunately i'm experiencing some of that, although my combo is a bit more than a stock longblock with a vortech
