I will be looking into going forced induction this spring, which blower would u guys pick??? I have a stock 06 k24a2 with I/H/E and kpro, trying to make the most power for the least amount.:coleman:

The rotrex is not a bolt on kit, you will still have to have a lot of stuff fabricated.

 

[ep3a2]

the intercooler piping or is there more fabrication needed???

 

[AscensionMotorsports]

you are right, just the charge piping and inlet piping.

I vouch for Rotrex. I do love mine

 

[ImportRacer2123]

Rotrex all day

 

[turpid porpoise]

rotrex

 

[NAcivicsi]

neither one of those kits will be easy... or cheap. the whipple will probably need a ton of cutting/ cursing for it to fit. the rotrex will need custom piping, intercooler, radiator, and whatever else is included.

 

[ep3a2]

rotrex it is, now to decide which size to get...cant wait till spring!!

Rotrex fan here.

That being said, I looked at the whipple website a few times...and I'm just not entirely sure what the distinct difference is between the Whipple and a roots setup. It just looks like a slightly more efficient roots, if anything.

Dealing with that massive manifold and hood/radiator clearance will be all kinds of fun, I imagine.

Most of its applications lie in the V8 world. This should tell you something.

What exactly does the "1.6 L" in front of the model number 1.6L AX100 insinuate, exactly?

It doesn't look terrible, I guess, but I worry about a few things more with this that I don't have to with a Rotrex. What does it do better to justify the higher cost over a Rotrex?

Just observations.

1.6L is the displacement of the supercharger- or the amount of air it moves per revolution (i believe). unlike a regular roots blower- like the JRSC- the whipple kit is a twin screw supercharger which has different designed rotors which compress the incoming air. I wouldnt say one is better than the other- seems more like personal preference.

Correct. The twin-screw superchargers are not "blowers" like a normal roots, as compression actually occurs inside the housing before it reaches the manifold.

I had a customer this year run the 1.6 liter 100AX from MercRacing make 456whp on a stock K20Z3. Said customer is now building an 88mm K20 and is going to turn up the wick a little bit.

Centrifugal superchargers are OK, if you want a torque curve that never reaches a peak until rev limit.

Torque breaks things. I've never driven either type of 'charger, but I like the power curve of the Rotrex because it is an NA-like powerband...and *should* be gentler on the drivetrain.

Torque also makes things fun to drive.

And a centrifugal supercharger doesn't "feel NA", really. Just an ever-increasing torque curve.

A roots-style blower has more of an "NA feel" to it than anything, a mostly-flat torque line, usually peaking in the middle of the curve and following the natural curve.

the rotrex is not that complicated to do. i wanted to build or fabricate everything myself & i had never welded anything in my life let alone aluminium.
so bought a welder and grinder intercooler BOV & wastegate & came out perfect even tuned by me.

so take it to a shop and it should be done in a few hours to the next day the latest. then get it tuned and have fun :new_slayer:

mine is a stock K24a4 2.4L vtec killer with C38-71 with maxed out pulley so it is torquie and feels way stronger than my mild built N/A motor & i got 4 psi more to go on the tuning.

give the rotrex a try. it won't disappointing you. if anything buy a large unit & run a pulley for 8psi or so & upgrade pulleys as you get used to the power later on.

 

[TaffyFG2]

Twin screws are amazing.

Die langsame

The biggest difference between the kit pricing is that the base price includes all the parts needed for the twinscrew kit. bolt on get a belt sized accordingly and go. Current limitation of the kit at the moment is the manifold size. once its modified you are in the 450+ hp without a sweat.

As for driveability D Rob at IMW tunes the vehicle very nicely and its very easy to drive around. Furthermore there are now tools available to make first and second gear very easy to drive if smooth lower power is desired at lower gears.

Fitment on the older Civics, etc is not clear at the moment... In a short time, options for using the CT Engineering manifold are available as well. We will be testing air to air setup soon for a very exciting and great looking setup and ensure clearance on lower hood vehicles... Got pipes?

Whipple's newest line of twin screw blowers are very efficient. They can be up to 85% efficient. That is in turbo efficiency territory. My average IAT's on a 1-4 gear pull was in the high 130's low 140's on the street. IAT's from the twin screw were consistently lower then my prior AC JRSC M62 set up. We hit 450+hp/300tq @ 20 psi without even trying to the 1.6L Whipple. With the same size pulley as on a 1.6L Lysolm TS we made 3 psi more. Whipple has been a leader in the supercharger world for some time and really have nailed it with these units. I cool the Whipple 1.6L with a Mercracing air to water system. The cars power is easily controlled. With almost 100 hp more then my JRSC set up the car felt more manageable and the acceleration feels smoother with that throw you back in the seat feel that we all love. When we were street tuning the car I couldn't keep a smile off my face. D-rob did a great job tuning the car and is currently assembling a Benson sleeved 88mm bore K20 with upgraded internals. Jose Mercado and I have been working together on taking it to the next level. We will be pushing it even further and reaching new heights for this community.

The rotrex to me is very expensive right out of the gate as a kit. The smaller kit is limited to under 400 hp. With cams I have seen them hit the low 400hp but at a high cost. To move to the bigger unit you have to get rid of some of the comforts of the car. Some people care about this and some don't. They make the majority of their power in higher rpm's and make less in the tq then a roots or a twin screw supercharger.

I believe that the twin screw will give you more of a "WOW" factor and make more power for less money. Basically a better bang for your buck. You will have more options and directions to choose from IMO.

12psi c38-91 k24 on e85
(In case you can't see 451whp 310trq) :dude:

IAT on a cold night never break 100.

 

[ep3a2]

They are both very impressive, to me i deleted my ac first thing so that wont make or break the decision but both seem to produce good numbers.

Looks like the rotrex made same power at less psi and im sure the boost can be turned up if needed to, is this the same with the whipple or is this its max??? Or is the E85 make that much of a difference?
