lsx engine blows up--update

[Goliath]

Take it to court brother. I would like to see who comes out as a winner in court.

GM says power adder. Don't see turbo or supercharger in the ad.

I define power adder as any method of supplying additional air or oxygen to the motor which it would not naturally be capable of ingesting. Headers, CAI, bigger cams, fuel injection, ECM tune, catback, highflow cats, N20, turbo & supercharger.

But the fact is, you voided any warranty with your setup.

or is GMPP wrong to tell custormers to run superchargers on these motors?

its says nothing about how long the engine can support power adders, it says nothing about whats size s/c or t/c it can support, it says nothing of how much nitrous it can support.

it just says that its capable to do so.


meaning that if you rigged up a sc or tc or even a nitrous setup on one and made 1 hp more than what its rated, then that engine can support it.


its an open-ended statement that doesnt specify anything about what levels it can be taken to.

and your definition may be different than the OP's and different from GM's.

Nitrous loves high compression engines. my LT1 in my 94Z28 was running 12.5:1 with spray.

superchargers and tc's do "need" lower compression, but nitrous works the other way around.

if all he's bringing is open-ended statements that do not specify anything then its not going to turn out too well for him.

That says LSX 454R. Yours was an LSX 454. The first LSX 454R was just auctioned at Barrett Jackson. Different engine.

so you admit gmpp statements are open ended and ambiguous. consumer protection laws will always favor the consumer whenever the advertisers advertising is ambiguous/open ended.
you state "its an open-ended statement that doesn't specify anything about what levels it can be taken to". thank you for supporting me.

the point is merely gmpp endorses the use of power adders with high compression, nothing more

It says it is capable. Not for how long though! lol How's progress on the new block going?

[Huggerorange73]

Let me get this straight....you supercharged a 13:1 compression engine, and are pissed because it blew up in your quest for 1000 rwhp?

Seriously?

If you want to push the edge of the spectrum, you had better expect things to go boom. If you dropped it in the car without the blower and it puked, then you'd have every right in the world to go after GM with both barrels blazing.

[franknbeans]

I'm on your side dude. . . regardless the motor shouldn't have blown on the dino. . . .

i did not do that!
i merely point out that gmpp endorses the use of power adders on a 13.1 compression motor

GM also said the drivetrain on the 5th gen was engineered to withstand 500 rwhp..

I don't know if I would use endorses....suggest maybe? And ya gotta use moderation and common sense. ( Although those 2 words rarely go together when you're talking horsepower )

And we're merely pointing out that GMPP also says that FI will void the warranty...

This thread is on life support.


Camaro5 is not here to be the bully pulpit...

You said your piece, there is nothing new to add.

Take em to court, let us know how that works out.

I don't see there's anything "new" to discuss.

[Irnwkrkev]

The pistons in the 454lsx motors (both use the same piston) don't seem to be a good choice for forced induction. Being 4032 forgings and high in compression even for the street motor. I'd like to see how the motor would hold up with a stronger piston and 1 to 1.5 points less in compression (9.5:1 or 10:1). Did you change any of the clearances -ring gaps or bearings- before adding the blower?

I'm saying that media statements like that intended to sell a product should not be used as a reasoning for trying what you did.

Tide laundry detergent didnt get the grass stains out of my football uniform, should I sue them for their media claims? no.



I am supporting you in the fact that I do believe there may have been deficiencies in the block.

But I do not support you in your original venture to throw a supercharger on a crate motor that wasn't built for it based off one guy saying that it was "ok".

what you should have done was what you are doing now with the RHS block and ordered an LSX bare block and had it machined to the size you wanted and complemented it with rotating assembly and heads/valvetrain that was designed for the boost.

their statement does not state that they endorse the use of power adders. just that the engine is capable of handling power adders.
