Hey can someone send me Greg's contact information? I am going to hit 1500 miles this week and will be ready to up the boost and dial in the tune.

You DO NOT need to have forged internals to have a supercharger!.
Anyone who has blown up an engine after installing a supercharger with
less than 14 psi has done it because of one or both of only two
reasons; 1) a tune that runs too lean or that disables or desenitises
the knock sensors, or 2) excessive RPMs.

Consider all the cars with cast or hypereutectic cast pistons with
boost levels from 9-15 psi. Ford Lightnings have cast pistons and they
run 15-20 psi just fine. There were over 250,000 Buick Grand Nationals
sold with cast pistons. Kenne Bell states that 99% of their sales are
for cars with cast pistons. If all these cars run blowing their engines
the they would not be in business.

One point of failure are the pistons. Pistons fail because of
detonation and it doesn't matter whether the car is supercharged,
turboed or naturally aspirated. Aluminum begins to soften at 1700
degrees and it doesn't matter whether they are cast or forged. The
forged will hold out a bit longer but basically the same. If the knock
sensors are working as designed they will retard engine spark and
eliminated detonation. But superchargers can make noise that can be
mistaken by knock sensors as knocking so tuners who are not as good as
others eliminated them or desensitize them, eliminating their ability
to protect your engine.

The other point of failure are the rods. There is a LOT of talk on this
board about how the rods are the weak point in the S197 drive train.
But I challenge anyone to show me a photo a of a rod that failed in
compression at boost of 14 psi or less. There are none because the rods
do not fail in compression, i.e. the power
of the supercharger bending them. They fail in tension, i.e. high RPMs
pulling them apart. The inertial loading (tension) of a rod increases by the square of the engine RPM. That means if you increase the RPMs from 6000 to 6600 you've increase the load on the rods by 40%. If you want more power, don't increase the RPM, increase the psi and keep the RPM below 6000.

werd and my car is still running over 500 rwhp and it has been to 7000 a few times on purpose but mostly not on purpose damn trans. This article couldn't hit the nail on the head any better. So Im living prof that they can make power and live.

Going to brenspeed on mon.They claim i'm coming home with 500rwhp .The 460 now seems good enough.The S/C has a small leak at the nose cone seal.They are going to replace the unit and put it on the dyno.Hope the weather gets better.

Wow I just joined this forum this week and this is a amazing thread to me. This is the very reason I hate to leave my car with people now.

You came out a winner in the end though it looks like.....

You have a bad ass car might I add...

Thanks Justin, It was a horrific experience so I am glad that it is behind me now. I am at 450 to the wheel and now after 6 months it feels slow again. LOL I dont know what to do next, It is supercharged with a smaller pulley, forged crank and bottom end, everyone has advice to get to 450 but after that the advice kinda slows down. I want 600 at the wheel but dont know what mod to get. Here is what I am debating:

Nitrous (Cheapest option)
Steeda belt tentioner upgrade with agressive pulley
Ford racing cams
or run Meth?

I dont know what to do next to get another 100hp.

What size is your current pulley? Put a smaller one on there if possible. It wouldn't be very expensive either.

ok forget the ford racing cam, get a good set of BLOWER cams, need to be ground specifically for a boosted application.

smaller pulleys the best way to go

I will check tonight and see what size pulley I am running. Thanks for the feedback everyone.

Is there a company that is affiliated with this web site that sells parts? Seems like some of the club members started something but I have been out of the loop for a while. I am going to upgrade my rear suspension in the next weeks so thats why I was asking.
