There's no reason to be dramatic about blowing engines because we don't have forged rods and a blueprinted crank. There's little experience with power adding on this engine from what I've seen and as people learn they'll see what works. |
"DUDE" Just what does that mean??????
You are right.The more boost,the more HP and torque,but at what cost.These engines have a built in stress factor,exceed that and your engine or any one part of it is going south.If you have a top PSI of 7 that will have a lower HP and TQ and a lower rpm,however a the rpms build very fast you cannot change the way they are put in the curve.They will rise gradually the same way a NA engine's curve will rise depending on when the cams allow peak HP and TQ.
Look at these engines.They don't put out 381 HP at an idle.Try to pull a hill at 800 rpms and that thing will laugh at you.You have to add A/F to the mix and it gradually picks up power and torque.
Change cam profiles and you change at what rpms you will reach top HP and TQ numbers.Only thing forced induction does is cram more A/F mixture into the engine causing a hotter burn and produces more HP and TQ
You may have had one engine with a blower,but talk to any engine builder and he'll tell you that each component has a stress tolerance that can not be exceeded.
Now if TRD is coming out with a SC that puts out 504 HP I'd say that is not far away from being the limit this engine can with stand.
Call Dave Maxwell at Crane Cams and tell him that Ron that helped test the Crane turbo cams in a 450 HP Dodge Neon told him to explain to you what and how cams and spark advance effect the TQ and HP curve of any engine.
Hell call Gary Howell of Howell Automotive,Rick Moroso about the prototype oil pan,Bill Hahn of HRC,they can all tell you about how an engine works.
I was not putting you down,I was only trying to add some info to the mix.Just trying to help.
Had a friend that built a 2 bolt main 468 BBC putting out 850 RWHP and blew out the bottom end on the first pass.
