Is it me but for road racing this should be the best option for Honda?


Less heat than a turbo setup in the engine bay and its water cooled


More top end than a Jackson racing supercharger

Seems to be a reliable kit, not many people use it because the price tag was almost 4600 dollars T



LHTs are a pain in the but and real expensive to setup


Sure its not as good as a rotex, but if its reliable then it should be a good alternative

 

No thanks. I have road raced non cooled and lht jrsc S/C's and turbo honda's. I have raced agianst and been around only 2 or 3 centrifugal s/c on honda's. they seem to never perform as the other 2

Also i'm unclear how you figure lht coolers are a pain in the butt and real expensive? There is Lots of PROS and CONS to all three.. Also the jrsc sits behind the front wheels so better weight dist than the vortec or turbo.

Also what tranny are they running to get 190+ miles per hour?

all in all its what you like to drive all with have there higher maintenance than stock.

 

You would have to find a old honda tuning for info on that car. There was a salt flat racer that was featured around 2002.

 

Positive Displacement Supercharger = Max boost at very low RPM. Linear power gain.
Turbocharger = Very non-linear power curve, turbo lag, but "unlimited" top end power.
Centrifugal Supercharger = Linear BOOST curve (low RPM, low power). Limited to engine RPM.

All in all, I'd stick with a PD Supercharger or Turbo.

 

I'm not talking about power, I'm speaking from a cooling stand point

 

Yes we realize your talking from a cooling stand point and your cooling stand point you didnt answer my question or explain how a lht is pain in the butt? you do realize the lht cooler uses one of the most efficient cores in his manifold that is water cooled...

There is lots of ways you can make a turbo/FI honda work for track you cant just ghetto fab it up and bam show up and rr it, Its not a 1/4 mile that lasts for sub 20 sec. These races last for 20 plus minutes. what makes a honda any different than any other race car thats turbo? nothing, besides little bits that need to be protected from heat that get taken care of from the manuf out of the box. but the motor is not some crazy thing from the future, the engine bay is not sealed tight of air... so whats all this "you cant rr a turbo/FI honda".

 

Vortech? what happened to the old turbo on a stick setup? I remember the clubsi guy had one and he loved it and it made good power.

 

I never said its imposable, but everyone agrees that its not easy to setup a good turbo car for track use.



Im simple talking about cooling not power!


Its water inter cooled already, and you can find them pretty cheap second hand


Since a lot of people have issues with sealing the bay and over heating


The vortech kit might be a good choice for a road racing car because the water cooler is already setup


Again im talking about this specific kit not wich kit makes more power

 

I think your missing the point. On the water cooling, On the heat issues, On the power, On everything. I have not made a statement on power but the more power the more cooling issues.

The lht roots supercharger setup IS WATER COOLED. You can have the turbo and the Intercooler WATER COOLED. A centrifugal with a water cooler is old news like 7 years ago the kit you buy has the option of coming with or with out the cooler depending on boost levels.

I am very lost where i mention which makes more power???

 

Just you. :p
The same air to water intercooler on that Vortech setup could be used on a turbo setup.
And less low end than a roots blower too.
These 2 comments back to back are funny to me. A LHT intercooled JRSC is cheaper than $4600 but somehow it's "real expensive"? Also not sure why it's a pain when it's basically the same components as a Vortech.

 

I would think the water in an air-to-water intercooled setup would most likely heat up beyond usefulness in a 20-30 minute session, negating the benefit entirely over the course of a session.

 

The water temps in the cooler dont get more than luke warm in 20 min sessions with 112 degree track temps

 

For which setup?

 

On my old teg with a built gsr on 12psi with a lht setup on it.

my buddy's focus is the similar on water temps with his s/c

 

It's very difficult to make an air-liquid radiator work as well as an air-air radiator. Yes water (or alcohol or anything else) has better heat-sucking-ability, but the proof is in the numbers. Air-air intercoolers nearly ALWAYS beat the liquid counterparts in efficiency under normal circumstances. It is possible to achieve over-100% efficiency with both, but it is likely easier with the liquid cooler.

Unless you want to pack ice in your intercooler, I'd stick with an air-air.

 

Yes but air to air only works with remote mounted S/C like a ie all centrifugal's or turbos and very limited amounts of roots/twin screw/auto rotors.

but again a lht setup is the the best off the shelf roots blower setup for our cars, becuase lets face it if your going custom and with a blower your going twin screw

 

I'd be interested in seeing a comparison of IATs between the water-to-air and air-to-air after a session on a warm/hot day. I know the LHT is good, and as good as you will get for that type of blower, but in general principles (and especially for the centrifugal blower shown in the OPs first post) I'm not so sure.

 

I have no doubt that a air to air is more efficient than a air to water in this scenario BUT like i said there are some things that you cant do

But if for whatever reason i had to go centrifugal i would go rotrex and run a air to air
