Which Supercharger and why?

[robjon96]

I am new to the forced induction field, but i am leaning toward a charger for the nightrunner.

my quiestion is....

what supercharger would you go with? and is there a difference in power? what would make more in the long run?

Roe's Blower type?

or

DC's centrifugal type?

or

another type / brand?

thanks in advance for all your input i know you guys have more knowledge about this than i

First..build your bottom end...


Roe = Torque Monster....you have instant torque off idle.limited to about 700hp unless NO2 is added..best for street..

Paxton (DC) = capable of more top end HP than Roe but doesnt have that low/mid torque....best for track..

 

[Begood]

I agree, if you are going to supercharge put forged pistons and rods if first. That way your block and crank don't get damaged by the broken stock pistons.

That is about all you need to know.

I can't add a thing.

Have you ever driven a vehicle with a displacement blower (Roe) or a centrifugal (Paxton)? The effect is the same in the trucks.

Like said above,
Roe= Riot on the street, crazy low end torque. Very steep torque curve.
Paxton= More horsepower potential, drives almost like stock until you punch it. Linear torque curve compared to Roe.

Basically it comes down to your goals and personal preference.

150 shot of nitrous and kick both there asses!!!:rock: :rock: :rock: :rock:

It's not always there when you need it though


BTW: I don't think your times have beat Larry's yet Jack:dontknow:

 

[moparracing]

regardless of what you choose, you must forge first & get it properly tuned......

as roy often says: good tune = zoom, bad tune = boom.

don't pass over nitrous as good booster..... striker heads, comp cam & 300 shot on forged internals would be my choice !!! :rock:

The things posted above are a nice start. But the rules are about to change.

First thing is you now have a reliable turbo set up on the market by JMB. So far the turbos (505's Jmb turbo and Stinkers) are the big kids on the block in the power numbers with the JMB being the current king.

Second, the ROE SC has the mastermind looking into a new intercooled intake. When that happens the top end cork will be moved up to a whole new level.

As for the Paxton, it has the fastest time on the timeslip section. It has been that way for a long while.

I like my Paxton, but I'm biased! 40,000+ miles with no real problems so far. :rock:

 

[tsmith3]

I also like the turbo for FI. I do agree with the guys above about building the motor first.

Stinker has a hell of a deal going with his motor swap program.:rock:

 

[TNVIPER]

I agree a turbo will wring out more power than a SC but remember that it will run around 50% more $$ to do it right.......

Or put the 150-shot of NOS on top of the SC! :marchmellow:

so i just got home from work and i read everyone post carefully, and yes i was going to make a bullet proof bottom end before i was going to plop a SC on. The real question i had was the difference in blower to centrifugal SC's and i believe it was answered but i want to make sure i got it right

Roe Blower is capable of 700hp and is very torky from a stop. but someone said there coming out with an upgraded cooler that could boost the competition. putting out bigger numbers like a centrifugal SC?

the centrifugal SC puts out a lot more power over all and has a stronger top end, am i right? so its basically like a turbo? kinda..

So if a blower type raced a centrifugal type the blower type would smoke it off the line but the centrifugal would come back and blow the doors off of it, is what you guys are saying correct?

does anyone have a link to a turbo set up for our trucks? i was just curious about the pricing and all, i know its going to be a good bit more i would believe.

Here's just my opinion.. With all of the money you will need to spend on bottom end preparation THEN buying a SC THEN installation, you might as well have purchased something else, like a SC'd GTS coupe. Eventually when the novilty wears off and your SC'd NR starts to feel normal to you (like it's stock), you'll be out perhaps tens of thousands of dollars and possibly will want to drop more on it. :dontknow: Just food for thought..

it has crossed my mind, but you can say this about any car pretty much. I see what you are getting at though

There are some fine twin turbo's around (Dom, Hilgee and Stinker are good examples).

Your comment about the Twin Screw vrs the Centrifugal is kind of correct but there are lots of other variables...those of us with the Roe have immediate power, but our torque makes getting traction from a stop difficult at best, I have spent possibly 20% of my modification dollars on traction which is still somewhat elusive.

You still have not addressed what you want to do with your machine...there are lots of routes to strong performance, but what you want as an end product is critical, because the paths are different depending on the desired end product.

If you are interested in over 1000 rwhp, you probably should start with a four-link, and tub your bed for some over-sized meat to get the hp to the ground, and your bottom end needs some pretty special adaptations not just a forged rebuild.

So again I urge you to think about where you are going...(begin with the end in mind!) and enjoy the trip...because you will always "Drive it like you stole it" if you are like most of us.

Dollar resources are another consideration...this is one of the most expensive vehicles you will ever modify. Our current record holder spent well over $100k. There is a $200k build in process and the end is not in sight on that one. Mine is a street quick machine at about 700 rwhp that is not designed for the strip...I have about $65k in it.

You will need a high quality tuner, that is highly experienced with your type of FI and the kind of tuning you decide on.

That might even be a good starting point...what technical resources are available to you in PA...then decide based on that person's input...you will need high level technical assistance.

In stock trim, the ROE and the Paxton have similar capabilities and limits. The paxton has more room for getting wild than the ROE does currently. This is intake limited. But Sean Roe has a project that about 20 of us have asked for, and that is to give us a more efficient intake with intercooler.

The real answer to your question though is not the power adder. These trucks have traction problems in stock trim, so it is exacerbated by all power adders. To truly use the new power will require also addressing the suspension. JMB has a traction kit. Stinker sells the upgraded rear axles and CALTRACS. Some, myself included, have ventured into 4 linked rears.

I'm not trying to talk you out of your quest for a SC. Lord knows they are an awesome power adder and the bling factor is through the roof. I had the same thing in mind and was an inch from purchasing a ROE SC myself earlier this year.. But then I thought about my stereo system and the many I've had in the past. Sure they sounded killer when I first had them installed. But then in time they weren't loud enough or quality enough for me anymore. So by that reckoning I decided not to spend $10k for a SC install.. I just decided to add little performance mods here and there to keep the wow feeling alive.. But that's just me.

As for SC's go, the Paxton looks bling with all the polished materials in the setup... But the ROE SC is an absolute showstopper as far as visuals. When it comes to which one (or others) measure up best performancewise, I'd pay close attention to what these guys have to say and spend less time reading my posts... :dontknow: Cause I may not know WTF I'm talking about sometimes.
