What are the limits of the high feature v6?
Hello. I'm hoping some one here has an aswer for me, it seems the internet is hiding what I'm looking for...or no one really knows.
I'm tossing around ideas for a project that I will start within the next 6mo. I was origianlly going to use an LSJ with a compound turbo set up so that I would get good low end torque but have insane top end too. I was planning some where in the 400-500whp range on low boost and in the 700-800 on high boost range.
But, At the dealership I work for, one of our long time customers had an STS kit installed on his newer v6 'maro (the LLT version v6). He's getting around 425 whp with 5-6psi. So it got me thinking...the v6 has pretty good low end with the VVT and already gets me to the whp I want for my "low" setting. But, how much abuse can those engines really take? I would get forged rods/pistons...I just don't trust hyper pistons and sintered rods (seen too many of those snap for no reason on n/a applications). Playing with cam overlap would be nice too help produce a nice torue curve (can use it to spool the turbos faster too). And that is something the LSj doesn't have unless I put and LE5 head on the block which they are not really that good for high hp; they are just not as strong as the LSJ head is.
SO has any one here started breaking the LLT yet? or know what power levels can be attained before bore distortion and head gasket failures become an issue? Has any one step-decked their block, if so what company can do that on this block?
