Another JRSC question

Tue Jan 22, 2008 9:31 pm

Just how hot does the manifold and sc actually get....like " it's a space heater", " you can cook an egg on it", or "better not touch it"?

I've got a concept rolling around in my head...yeah I know...another one...

If there was a way to control the sc/manifold casing/exterior skin temp...then there would have to be some benefit. Cost would be inexpensive. I would have to wonder though, if you were able to do this, would the metal be more susceptable to cracking?

probably all depends on how hard you drive it...why are you so worried about temps? I imagine the blower's designed to handle it, and underhood temps probably can't get too much warmer.

I'm not worried. Just looking to free up some power.

i personally think "you can cook an egg" sounds about right. When i had mine, I rested it for 10 minutes with big fan blowing thru it after 1st and 2nd pull on the dyno and on the 3rd pull i gain about 4 more hp on the chart.

There was a guy that fabricated an intercooler setup on a custom JRSC setup using an M90 Eaton.

I believe he used Volvo intercooler stuff and may have been running the blower upside down on the manifold but I don't remember exactly what he did.

Why not run one of the inline coolers like Kyles got on Chromie and some Meth for good measure?

If you just want to cool the case on demand you could rig a Nitrous tank or Co2 tank to some jets to blow directly on the case when you want it to.

Both Ford and some aftermarket companies have also dabbled in using the vehicles A/C system to provide on demand extra cooling for forced induction and from what I've heard it works quite well.

the jackson mani is easy enough to band saw in half( uper and lower) fit a cooler in it and fab the mani to be bolted together. or no2 is very good at cooling things. the problem with the older jackson kits is they are to small(m40 up to m45) the new kits i think, may be wrong, run a 45 for the zetec and a 62 for the svt. the bigger compresser is actually more efficint and runs cooler. in my oppinon the jackson doesnt really cut it. ive read about them and there 300 - 400 degree charge temps. the bad thing about roots blowers is there inabillity to be packaged in the engine bay. look at a procharger,vortech,paxton.. not only are they very linear in power out put but the packaging of the kits allow way more flexability. but if it were me id run some 3/8s to 1/2 inch line around the compressor and then into a wet nozzel system.

The Zetec kit has always had an M45 IIRC. I've been looking into laminova cores. It may be easier to fit these. I was originally thinking of a water cooled heat sink.

I'm assuming the Jackson is similar to the Centrifigal on my car, with the colder temps, the blower can run more consistent with lower temps, and with the cold air coming into the motor, the motor can use the air more effiiecent.

I'm not sure on how you can get colder air into the Jackson tho, since the blower is pretty much part of the mani I believe. Unless Chalon has an idea cooking'...

DEI makes a CO2 intake cooler. This would be pretty easy to do.

dont waste time with cooling the intake air, it gets heated by compression. this is why a cooler is always on the charge side. the best way to cool on a jackson is meth injection. but like i said before if it were myself , id run nitrous through a line coiled around the housing and then into a wet nozzle system this way the spray cools the housing and the incoming air to work as a doble buffer aginst heat. when you cool the housing the charge temps drop, when the intake air is around 40-50 degrees below freezing the heat in the compressor wont raise the temps to drasticly. another way is to use a cryro kit adapted to the fuel rail and lower half of the jackson mani. i have been looking at o2s setup and i like the way that fits, and the air-liquid-air cooler is a nice touch.

anybody here have a degree in metalurgy?
reason i ask is i have a cryo design in mind and its very feasible to build, but im unsure of thermal shock to the s/c and mani.

I know what you mean. I'm not sure what rapid cooling of the manifold/blower would do in the long run.

I don't believe there is any problem with the using the air intake. Sure, the air's gonna get heated, but not as much. Then, combined with the cryo fuel bar, you'll spray freezing cold gas into the cylinders. There has to be benefit.

Is it better than wmi, probably not.

at one time yes.... think of it this way, if it never reaches critical temp( where the chemical makeup starts to change) how are you gonna shock it? set the co2 vent selinoid up to a temp sensor( like on a cooling fan) to blast the housing at certain temps. cast alum can do some really neat things, thats why engines are made of the stuff.

Dumb question but if WMI is the clear winner why not just use it?

You could go as fas as supercooling the WMI for some extra added punch as well.

i agree, they used meth injection as far back as early wwII with great sucsses. even n/a motors can use it for supree timing advance. it just sucks that you need a system to adjust for spikes and also to retard timing when the alky runs dry.
