Blowers take power to make power and because of this are less efficiant...
But, if your comparing blowers to turbos on a 5.0, I prefer blowers.....

blower- easier to install, easier to tune, can be smog legal, a little cheaper
turbo(s)- more power than a blower, easier on the motor for the given hp numbers, more torque, full boost faster, no belts to throw off, sound sick as fuck, car can be quiet as stock and have 600rwhp, its something relatively different
i like turbos, i am nto afraid of the tuning or the install
but a s trim would be 10x easier

Ever heard of turbo lag?...You have to wait for exhaust pressure to build before you can get boost...A blower is always spinning and can basically build boost instantly... ![[patriot]](graemlins/patriot.gif)
One thing I hate about turbos is the amount of under the hood temperatures they create...

a blower can build boost instantly correct but wont see full boost untill 5k or redline, a turbo CAN see full boost by 3k Ill let 93 pony and the other turbo guru's handle it from here

Turbo lag can be an issue in a small displacement low compression engine. A 5 litre feeding a single turbo can produce a LOT of exhaust pressure pretty quickly. While a Roots style blower will create boost right off idle, a properly built turbo setup can launch with 5-6psi no problem. Go go auto!
All this being said, if I had to do it all over and it was smoggable, I'd have turbos.

LOL ![[BS flag]](graemlins/bs_flag.gif)
A Kenne Bell or twin screw type blower can achieve full boost at 2,000rpm rather than 6,000rpm with a centrifugal like Vortech or ATI...
Do you know how a turbo works?...Generally speaking, most Turbos wont build boost as early as a blower could...You can get a small turbo to spool up fast, but then you loose the total boost advantage...Turbos work off exhaust pressure, you have to build exhaust pressure to get boost...A blower runs off the crank and as soon as the crank goes the blower goes...
I love my turbo!..It has great torque and I've bypassed the factory boost controller to get full boost early(around 3500rpm)....I think it's more of less a personal preference as to which you prefer...I love both!

It really depends on the combo, the intended use of the vehicle, and most importantly your budget. I think easy answer would be a turbo for the aforementioned reasons, but in many cases, superchargers work just as well, if not better.
turbo lag??? i thought thats what 2-steps were for ![[Confused]](confused.gif)
ive had this talk with 93 pony several times, he prefers n/a cars.

Yes I know how a turbo works ![[Roll Eyes]](rolleyes.gif) especially on a V6 but thats another story. I guess it depends on witch type of blower he is talking about, roots or centrifugal. A twin turbo setup on a small block v8 can acheieve full boost at a very low rpm and lots of it, therfore not loosing the boost advantage. Not to mention less wear on the cranks bearings at higher psi from the added stress caused by the belt on a blower. I will agree with you that a roots style blower can achieve boost quickly, but it also makes a ton of heat. If it were me and you are stuck on picking boost, then I would go with a turbo. If emissions is a concern a ATI with intercooler or Vortec with aftercooler and no matter if its a blower or a turbo the NX N-tercooler kit also
If the car is a street car though, i would look into nitrous, much better on the street than boost in my opinion. Cheaper inital cost and you can turn the extra power on with a button whenever you need it.

im mainly focusing on a lot of power for a lower price. so it sounds like a blower will fullfil my needs(price wise.) what do you perfe, vortech or ATI procharger? thanks

Full boost at peak torque is simply incredible! No centrifugal SC that I know of can do that. Roots produce a LOT of heat & are RPM limited by design.
A turbo motor will make more power under the curve then any blower setup Period.
BTW, turbo's run off heat as well as pressure.
Most 96+ cobra's make ~390-430RWHP with Blowers & all the bolt-ons.

My S-trim makes good power ( over 400 at the tires). BUT, if I was going to do it over again...... turbo. And BTW, Shaun (93PONY), gave me an asspuckering ride in his car last nite. It is fucking insanely fast. Fastest car I've ever been in.

What do you mean by this?...When you say power do you mean boost?...Because comparing a blower and turbo for power is hard due to SO MANY different combos....
Shuan, You can't tell me that you can get 8psi at only 2000rpm...

Nope, but i guess you can "sort" of get away with it if you have race gas. But definetly low compression for boost from wither turbo or blower.

A Kenne Belle can make good boost down low but they make no top end power. Bolt on any Centrifugal blower and it'll spank a kenne belle at the track. Bolt on a turbo with the same boost and it'll spank both blowers.

Do a search in this section on blower vs turbo. Fasterdamnit had a very interesting article scanned in about the same motor with a roots, centrifugal, & turbo bolted on. The turbo spanked ALL other setups.
It's an article from August 2003 Hot Rod magazine.
Power under the curve = Average power from a given RPM to redline.

Really depends on your tune, and if its a roots blower vs centrifical, I have the stock 03 cobra roots blower and it kicks in at 1900 to 2100 rpms and goes just about straight accross the board, a constant pull. Depends on the Tune. A centrifical blower needs to spool up a bit kinda like a turbo. Both have there pros and cons.

With almost any power adder the main enemy is the heat build up that power adder itself creates. That's why there are inter/after coolers and things like water injection.
In any case you end up walking that fine line of air-to-fuel while still trying to keep the unwanted heat build up to keep away from detonation. That is why the race gas helps....to keep the det./knock down to an acceptable level so that the AFR can be kept in your particular "sweet spot" .
All of this in combo with accurate corresponding timing will make SAFE POWER!

To put and end to this silly arguement...
Take a look at any "street car" racing body. Heavy Street, EZ Street etc. and you will find that turbo cars have a weight penalty slapped on them because turbos are fair to the competition since anytime a turbo car enters the field it woud win if there were no penalties for those now wanting to run a turbo ![[Wink]](wink.gif)
I agree with the above, yeah twin-screws can see full boost faster than a big turbo setup but then they lack the top end power. Turbos are much cooler in the fact that it is easy to adjust the power. Get a dual-stage boost controller an dyou can have street friendly 5-7psi but flip the switch and now you have 10+psi AND can add an Alky kit like I am to auto arm when in hi boost mode and it's like switching tanks to race gas and bigger intercooler
That's why I gave up on blowers and am having aturbo installed this week.
