Options and opinions on supercharger safety, discuss.

**1fastsedan** · 02-19-2009, 02:46 AM

So I've been running my 8 pound Vortech kit on motor with heads, cam, and a stock bottom end for over 6 months now. I've seen every supercharger kit produced toast at least one motor. I want to discuss some supercharger safety tips and tricks. Below is what has worked well for me. This is my personal experience and opinion, not any hard cold facts other than its worked well for me.

Blown motors come from 2 sources, heat and detonation.

HEAT: For those that don't know, compression generates heat and raises intake air charge temperature. You're motor then compresses all that hot air again, generating more heat. That heat then closes the gap on the piston rings causing them to go solid and pop off the ring land.

HEAT HELP: good tune, aftercooler, and water/meth injection (chemical intercooler)

DETONATION: With increased compression comes increased likelihood of premature ignition within the cylinder. These uncontrolled ignition events can easily break pistons.

DETONATION HELP: good tune (especially at part throttle), aftermarket fuel rails with front crossover and 3/8" fuel line if running 8 pounds of boost or more

I consider the aftermarket fuel rails and water/meth kit essential additions to stock bottom ends with boost.

i have to agree completely.

I am very intrigued by the water/meth injection. Can I ask when you have yours set to spray? Does it only spray at WOT?

Thanks, Wally.

my meth/water kit is run off boost, it starts at 2lbs. and is full on by 5lbs.

I agree...also a air-to-air intercooler has been proven to help with the intake air temps (Heat). It actually performed way better than the aftercooler. Might want to look into that route. This would add to your security blanket.

IMO, a built motor is like a insurance policy. I would feel better to "Have one and not need it vs. need it and not have one" ....

Thats why I jumped on one the 1st chance I had.

The Water Methanol kits I sell (and use on both my Turbo Diesel and S/Ced Hemi) are injected based on the amount of boost the controller sees.

On the standard controller there are two dials, the 1st one is the initial starting point for the controller to come on at 10% volumetric spray of the Methanol.

The Digital controller is a little more tricky and goes off the Injector Duty Cycle and can be more precise when it comes to the injection...this is the one I use in my vehicles.

I am going to start another Water/Methanol Group Buy soon, yall stay tuned (tuned...get it)

I crack myself up sometimes.

I haven't seen any advantage with air to air over air to water coolers. I think its more of a personal preference kind of thing. You definitely should have one, but I haven't seen one type outperform the other.

Agreed!

**MOL SRT-8** · 02-19-2009, 04:39 PM

i am sticking with what i have.

I'm confused. I always run only a few degrees above ambient with air to water set-up, so what's the advantage. Plus, you lose boost with air to air so you have to generate more heat by spinning a smaller pulley to make the same power. I know that GSM's air to water cooler sucked, but that doesn't mean all of them do in general.

Don't get me wrong, I'm glad that you like yours and it works well for you, but its not the only option. Its your opinion that they work better, fine. In my experience they're about the same and are both viable options for safety.

The air to air doesn't lose much boost.Cruising around town temps are not much different but WOT the A/A runs cooler,especially once your at the top of second and third gear......but remember I am talking 10-12 psi not 6-8.

That's why I put the ice in aftercooler coolant at the track.
