How Much Horsepower Can A Lt1 Handle. All it takes is wheel hop. The weak point right now is either the trans or the truetrac.

So far it's holding 640/610 with a twin disk clutch, 1000hp ds, axles, and stubs. But they had methane injection, at least #42 injectors, engine girdle (i think) etc. The ring gaps inside these motors are so tight, its hard to safely make power above that without having a ring land failure.

The lt1 can handle up to around 700rwhp reliably, but there have been cases before that and after that where the ring gaps have caused issues. Saying 10 bolts are weak isn't true because the 8.5 10 bolt can handle a lot of abuse. There was a shop (i forget who) on ls1tech.com that was getting well over 700 hp on a single turbo formula with 98000 on the clock.

Bear In Mind That Those Numbers Can Change With High.


The weak point right now is either the trans or the truetrac. The stock lt1 fuel system is good for about 600rwhp, much past that and you need to upgrade the fuel system, and the stock zl1 fuel pump doesn't take you much further. The 4th gens got the weak 7.5.

Something for people to consider. There are a lot of auto tans cars that have broken the 7.5. The block and crank can take upwards of 900rwhp.

Gm made several different sizes of 10bolts. This has been holding together for about a year with a lot of spirited driving and about 20 track passes on drs.
