Anyone tried Paxton/Vortech supercharger 4.0L?

Has anyone tried a Paxton/Vortec supercharger on a 4.0L Toyota? That Magnuson supercharger is expensive.

 

For all of the whining I've read on here about the lack of power, lack of good horsepower gains, and lack of smooth power transistions I am shocked this thread hasn't gotten any input. Thousands of dollars less than the Magnuson supercharger and the potential to make more power (and potential for less power if desired) than the Magnuson.

It is typical for a lack of response to "out of the box" thinking though. Around 3 years down the road I'll probably dive into it head first.

 

I mean what do you want, plenty of people have done centrifugal superchargers. The truck ECUs are tunable now thanks to HP tuners. Just have to make a kit that can mount it up to the belt drive and pick an appropriate pulley size. There's been a centrifugal SC kit for the 4cyl trucks for years. It's not rocket surgery but most folks didn't want to do the one off work to mount one when the roots style charger can get you almost into the 400s with smaller pulleys, solid tune, has an integrated water to air intercooler, and already fits the intake manifold and belt drive. Works with stock intake plumbing which can be important to some folks. Does it all add up to what they price it at, maybe, maybe not. Folks have done turbos too. Maybe talk with those folks, if you're shooting for more power than the roots charger things will start to get real spendy again as the engine isn't built to take a ton without some help. @Torspd, @12TRDTacoma, @GT7, @Roostfactor probably know the most about all that

 

Nice input speedy.

I gotta do a lot of research on it but I've got the time to do the research. I need to study more about mods on EFI, which I know very little about. I also need to do research on the engines stock internals (forged/cast/compression ratio, etc).

 

I personally do not see a point in doing a Paxton/ Vortech style blower on the 6. The 6 version of these trucks require you rev the balls out of them already just to get into their powerband. The whole idea is to get more torque down low which the Magnuson blower gives you more of due to the fact it is a roots based blower over the centrifugal design of the Paxton/ Vortech blowers which is in a way a belt driven turbocharger.

The drawback of course is obviously there is a power drop off once you get into the higher RPM range. You still want to avoid revving this thing high if on a roots blower unless you are strictly racing the truck (then a centrifugal is worth it) at which point I would say get a race car instead as it is aerodynamically an easier endeavor unless you got the money to blow.

It just really depends how far you want to take things with your truck and what your goals are, but personally, many people are happy with their M90 including myself. Plenty of power on the Taco.

 

Thank you for the reply. I am definitely not an expert on this topic but I was thinking a centrifugal blower with the appropriate pullies would actually be better than a roots blower for the application. A smaller pulley on the centrifugal blower I think could have more boost at a lower RPM than a roots blower and the centrifugal blower might have less pressure output at higher RPM's than a roots due to its design. It might be easier on the engine than a roots blower, especially at higher RPM.

 

...and much more boost at higher RPM which I doubt our little engine can handle.

 

Thats why theres a lack of interest. People are actively modding w/ magnuson. You don't plan to do anything for 3 years at which point, you likely won't anyway b/c you'll have moved on to another idea or vehicle. Had you posted pics of your current build with a paxton, this would've received considerable interest. I'm sure.

 

Let's say two identical trucks except for the supercharger, one with the Magnuson and one with the Paxton. Both put out equal boost at 1,000 RPM's because of the pullies chosen. The roots will have more boost at 5,000 than a centrifugal and that equates to a combination the engine will be less likely to survive. The centrifugal can also be set up to have more boost at low RPM and still have less boost than a roots at high RPM. More power where it's needed for the application.

Does that sound correct?

 

No the centrifical will pass the roots in boost. Roots chargers are positive displacement and tend to Peter out at high RPM

 

I'm not most people. Thank you for the reply.

 

Oh that is definitely the opposite of what I thought. Thank you!

 

There was a guy on xru years ago that made a custom bracket to run a vortec supercharger. No issues from what I remember.

 

I'll have to look into that. Thank you!

edit: There is a kit already available of what I have in mind. About $5,500. I'm positive I can build my own for much less cash. I'm going to keep researching the topic.

 

Pretty sure Procharger has a kit coming out for the tacom and 4runner. I definitely wouldn't go with a centrifugal for offroading though. Most of your gains will come higher in the RPM range.

 

I'm glad I previously wrote I'm not an expert on the topic because I've proven I was correct about that. Lol. Thank you!

 

ok
get back to us in 2022 with some updates then.

 

URD's superchargers are centrifugal, have been around a while and some people out there have them. Do a search on them to get an idea of what they can do and the pros and cons for that style. For lower power band and torque the roots has always won where the centrifugals are solid in the top end but take longer to wind up. The centrifugals have played around with pulley sizes plenty too.

 

I was going to say the same.

I didn't want to go with a turbo for the same reason I shouldn't go with a centrifugal. I just was incorrect on where centrifugals make their power.

I have plenty of time to do research on it. I'll definitely have to register the truck out of state before I do it and I have several friends I can ask if they're willing to help me with that.
