Mattsv8 Posted October 9, 2012 Report Share Posted October 9, 2012 Poblem really isint the fact that its a turd to 5000 but 520 whp andonly 400tq. They would be way better off shifting the powerband down to pick up tq. That's the issue with most imports. They can scream up top but no tq.

If they tried to make 400tq earlier on the rods would exit the block..... Quote Link to comment Share on other sites More sharing options...
GSXRAntwon Posted October 10, 2012 Report Share Posted October 10, 2012 BTW, this is what's holding all that cylinder pressure in: Depending on how strong the factory rods/pistons/crank is, the open deck will be the limiting factor, just like Honda motors. A block guard will cure that. Quote Link to comment Share on other sites More sharing options...

A block guard will cure that. Truth. Wonder what these blocks are finally going to pop at. Im assuming probably in the 600-700 range. If they hold more than that i really be SERIOUSLY impressed. Also, when i was reading through the thread earlier about this car i thought they said they were at 9.5:1 compression. Found it The heads seem very efficient so far. We are going to keep the compression around 9.5-10:1 But is it 9.5:1 or 10.1:1, sound like by the way they said it theyve tried both?

thorne Posted October 10, 2012 Author Report Share Posted October 10, 2012 I thought they were referring to there planned built motor. Being that ap @18psi made 426 with 30rsized turbo I don't think they have lowered compression Quote Link to comment Share on other sites More sharing options...

spankis Posted October 15, 2012 Report Share Posted October 15, 2012 I always remember the GM Ecotec motors having a reputation for an extremely stout stock block setup. Anybody know what they are good for? I vaguely remember reading about a stockish 700hp Ecotec turbo car... Quote Link to comment Share on other sites More sharing options...

The LNF was maybe 400's before internals. But yea a pretty good engine... the big problem was front-wheel drive. Quote Link to comment Share on other sites More sharing options...

Mallard Posted October 15, 2012 Report Share Posted October 15, 2012 The LNF was good for over 400 HP, and I haven't kept up on it, but I don't think anyone found the limits of the block, just the limits of the DI fuel system. There were stock block LE5's (2.4L) pushing 450 HP. Quote Link to comment Share on other sites More sharing options...
