No idea what the LSA's ceiling is. The Caddy guys are doing minor mods to get a little over 600 crank hp out of it.
Lingenfelter has a warrantied kit designed to boost power to LS9 levels...they don't replace any internals.
And Hennessy has a kit good for 700hp without replacing any internals...no word on a warranty...though I didn't check very far into it.
Let's put it this way...the engine won't blow up if you do a little modifying.
But I look at it the same as the LS3. But you wouldn't put 600hp through a stock LS3 without worrying, and so you probably shouldn't put 800hp through a stock LSA without worrying. Even the LS9 with all its titanium isn't indestructible........
I personally doubt that the GT500 guys are putting all that power so easily with unaffected reliability...but I can't get
any specs on the engine from Ford...they're nowhere near as transparent about this stuff like GM...it would make this discussion so much easier.
