Supercharger or not?

The motor should be able to handle the 1000 kit without any real problems IF IF IF IF IF you get it tuned properly. If you put boost on top of it, or go with the 1500 kit, you may want to consider a forged bottom end (crank, pistons, connecting rods, wrist pins, cap bolts). Then I'd imagine you're good to the mechanical limits of the tranny, driveshaft, rear end, axles, etc. I believe someone said the tranny is good for 700hp.

And don't even consider doing aux fuel injectors for the extra fuel. Go with larger injectors and figure out how to tune it that way.
Do some searching here on the superchargers. Lots of stories as to what happens.. Maybe you should wait for the turbo kit that Amber/t is working on. He at least is using a proper fuel delivery system and you at least will have less risk of torching cylinder 1 by going lean. (aux injectors are risky as you can't guarantee fuel to all cylinders equally.. your wideband may say things are good, but you could have 6 cyls running rich and 2 super lean.. )

·If you are really thinking about it, read Obiwan's posts about his TWO blown motors.
It's ok to do on the 6.1's, but the 5.7 cannot handle forced induction unless it is tuned very well. And I'll tell ya... I bet even tuned perfectly you are GREATLY reducing the lifespan of that motor.

I have heard of 6.1 motors blowing on the s/c kits as well. Not something the people it happens to want to talk about, but it has happened. In my book they just aren't safe.

I would say no on the supercharger kit until somone does it the right way and actually test the cars before production.
Its hard for me to believe that our 5.7s are that weak they can't handle a little boost..I have seen little dodge neons with the old paper head gasket take 5 psi and run like stock...with the proper fuel delievery and managment..we should be good.

I not going to rule out and say a SC is not safe..Now the current kit that is sending a lot of our fellow HEMIs to there maker...HELL YEAH. I knew something was up when I saw that low budget aux injector setup that who ever bought the kit is in for a nice ass bang.:doh:

Your on the money about the injector set-up. But our piston design blows................hahaha...........get-it "blows".............Uh ya OK, I'll shut up now.
The upper ring gland is to damn small, .125 thick. The major problem has been with the compression ring flexing and breaking the top of the piston off. Many people have stated this is due to the ring end gap tolerances being to tight.
Fact is, it don't work on our stock motors. :sad:

if its GSM and you wanna blow your engine get it! If you dont wanna blow your engine don't get it!
only works if...
you build the motor first.
Bolt it on and play with fire. Can you afford catastrophic engine failure and expensive repair?
No one with any experience puts boost to a stock motor with high compression. A little spent up front will greatly reward you down the line.

your right, some what..lower compression will just give you a bigger window for tunning..Higher compression you have less room to play with..I bet if the current kit was put back into testing with 8 injectors, return line, aeromotive fpr, and something to control all these goodies..things would look a lot better on the bright side..Now don't read to deep into my post..im not saying you would be able to run some serious boost..but the 5 psi that people are blowing there motors with should be a cake walk..anything higher I would recommend dumping some money into the motor.
Me personally, if I go turbo or SC...Im building the motor..Thats because, I have been down this road before and its not new to me..

It seems the consensus here agrees that it is VERY risky adding the SC to a 5.7 and even a 6.1.
No it is not my intention to destroy my engine at all. Iknow GSM has an SC kit using the Novi 1200 and I figured this one being offered to me was a Novi 1000 (Less boost less risk right?)
So I guess Im going to keep looking into the Nitrous route. Either Nitrous Express or Zex 100 shot setups to use at the track.

Even with the bullet proof motor they custom built for me, it lasted a whopping 6 months. But if you have cash in your hand your their best friend and they will bend over all kinds of ways to kiss your @$$ once they have your cash, you'll be lucky to get them to return your voice mail.

So I take it that you finally got your answer about the bottom end.
Sorry bud :sad:
So what do you think caused it this time??.
I got the answer from them when I called and told Scott the motor let loose. Asked about warranty since he built it and tuned it, said sorry its custom HP no warranty.
I still don't know what happened to mine, right now riding a BMW R1150RT to get to work, end of October I start working from home for a month and a half so that will allow me time in the evenings to tear into it.
Now if I could get those HEAT guys to ship me a motor...

Find pieces of your piston on the oil pan? i bet cyl 1 went lean and melted down.. Pretty crappy that they would not stand behind their engine work. :doh:
Maybe with a proper fuel system they could handle a little boost.. I think the best way for us to make power is with cam, heads and spray..
Oh, and vinyl.. I hear graphics add horsepower too.

Yeah, all motor is looking more and more better these days..but 5 psi should be a walk in the park with the right fuel system and tunning of course.:loser:Find pieces of your piston on the oil pan? i bet cyl 1 went lean and melted down..
