Stock GM LS Engine - Big Bang Theory

[2002ssslp]

How about a 427 with a turbo. Why not have the best of both worlds. If the engine is put on an 8 to 10 psi boost you should be well in the range of 700 plus HP.

Two problems with that.

1. My 427 is 11.8:1 compression, not very good for FI.
2. Right now, I'm eyeing that 600rwhp mark with my N/A 427. If I'm going to drop $5k-$10k on a nice Turbo or Supercharger install, I'm going to want more than 700rwhp.

Like I said earlier, for my next build, I'm going to completely remove my 427 LS3, install it into a RX-7 or Miata, and build a new motor using the LSX block, and THEN put a turbo or supercharger in front of it.

I think this article disproves that theory completely.

Not really. I am willing to a bet a LS1 built for boost wont make the same amount of power as a LSx of 500ci built for boost. Thus cubes wins.

That 427 better be built for FI. Whats nice is that the LS1 isnt a SUPER high compression ratio engine so you can boost it pretty easily.

You know that quote means "displacement only"...it's common sense that boosted hp increases with cubes.

that is just, nuts. All they really did was change the ring gapping seriously? So youre saying if i popped my ls1 out and put new rings on it with new gappings i could do this with my car?! haha

Yeah, but I'm not sure how I can go from a 427ci to a 325ci and still brag about it...granted I'll have two turbos, but still...

Guess it depends on what you want to brag about. Having 550rwhp with a 427ci motor or having it with a 325ci. Naturally, getting more power from a NA engine deserves more bragging rights. Bottom line though is winning is winning

That's cool and all, but let's see how it holds up on the street with some stress on the motor. Easy to spin a motor with no strain on it.

You can brag all you want after kicking some Mustang Ass. It doesn't how you get there, just get there first.
