procharger...... bigtimeauto runs one and is way faster than metalstorm and hits roots by like 2 seconds.....

So...in benchracing, one type of blower is better because the car is 2 seconds faster regardless of vehicle weight, boost, engine size, head design, etc? No offense....that sounds like what I hear when most ricers talk about their 18 second cars...a bunch of nonsense.

As said, don't listen to anything he has to say about superchargers!

WOW, tons of misinformation here i'm flattered!

Just buy what you want....... but there is no way a 6 0r 8/71 roots with carbs on gas will drive around a procharger on gas. Now a roots injected on alky well thats a whole different story.(so is that C rotor screw)

My street car:

3150lbs
NO intercooler
cheap Blow thru single 4150 carb
can drive it anywhere, we took it to lunch and a ride today as a matter of fact.
......it still has not made a full power pass yet

I didn't mean that roots is bettr...I was just questioning the logic of his question.
Big time...how much compression? Race gas? pump? How is drivability with the blow though? I've always wanted to do that....

depends what kinda power you are looking for, with a 540 or 572 you could prly make 1000hp with a small d-series procharger, I personally like all there f-series blowers and would recommend an f-2 just so you have room to grow (since you know you'll want more)

Now on topic:

Roots on the street Pros:
positive displacement
great car show appeal
great WOW appeal driving down the road
cons:
Heavy
needs two carbs or ...
can't see past it with carbs and air filters
can't use a air to air intercooler
is way high and atrracts the wrong kind of attention
can only run low boost on pump fuel because of all of the heat it makes

Procharger on the street pro's:
no hood issues.
only need one 4150 carb
the cops can't see it
builds less heat
lighter than a roots
easier to package
can use your existing intake
intercooling does not impact your vision
can use a air to air intercooler
Cons:
hmmm none i can think of

This is EXACTLY why for me..... Whats funny is some of you guys instantly think of fuel blowers for comparison... I seen way too many 11-12 second big blower cars and that just not for me is all.... Remember Denny Turza's or whatever his name was that ran Drag Week with the Big Roots Blown camaro.... He was out of competition like 10 miles after starting the event and WON the next year with a pro charger driving 1200 miles

how much does the procharger complete weigh?
you are right i cant see past my blower.
a plus for me is a stock carb[s] will do.not boost referenced[race only]
my blower weighs 70lbs
intercooler 40+5 gall of water 40+lbs
