I agree E85 is helping a lot ..but one thing I noticed on stock turbo setup is that it does not carry no matter how much boost you try pushing ..they always taper down to 16psi by redline and that is the MAX I have seen ..on my car with actuators ( old setup) Jack could not get it to carry more then 14.5 psi at redline.. I think in some way it protects the engine

And Neil ,IF I owned your E900 package I would be ****ting a brick pushing 806whp on STOCK block let alone 580 hp but I guess you guys warned the owner.

 

We backed it down for the street and a disclaimer was put out there, however Jamie knows his way around boost controllers too well...

I have seen what the stock turbos can do at the strip and on the street, I have also seen what they can do to an engine block, and that is all the proof I need...

 

that is super impressive for essentially a bolt on car+e85

 

Oh i agree..pushing hot air is a recipe for disaster regardless of the boost number...
just saying stock block can handle 700whp for a very long time if the tune is good.. i did see the AFR on the dyno sheet for sleepdoc and it was pretty safe at 11.6 ish and zero knock..

 

Very nice my friend
