woodhog Posted December 31, 2014 Share Posted December 31, 2014 I have a E7 350,I would like to know if I put a E7 460 turbo on it will I have any performance gain? I currently am pulling 27-30 pounds of boost and pyro runs about 950 to 1050 on a good pull. I also have put a air to air thats supposed to cool up to 1000 hp.I do have some fuel turned to it. I would like to know halls opinion on how to get more out of my little dog. Quote Link to comment Share on other sites More sharing options...

theakerstwo Posted December 31, 2014 Share Posted December 31, 2014 Also double check your timing.Some guys want to advance the timing too much.I installed a turbo from a 427 HP on my E7 350 and it cooled the EGT down a lot but I have the fuel set up on it also.I gained about 6 psi when I changed but the big thing is I now can stand on it for a longer time before the EGT comes up to 1000 1 Quote glenn akers Link to comment Share on other sites More sharing options...
6368 Posted December 31, 2014 Share Posted December 31, 2014 I've always wondered why they could have an electronic 454 based on that same pump. But only a 350 Mechanical. I' am guessing emmissions might be the answer. i kinda recall that that is what killed the early e7-400. Anyway how hard would it be to build a 454 mechanical from 350?

theakerstwo Posted December 31, 2014 Share Posted December 31, 2014 Just forgetting the emissions I would say that you could build a mechanical big horse engine but the main thing is it would be so easy to damage with out the electrical timing.a mechanical pump is fixed timed.A hot engine needs to be able to change the timing all day long as needed.To keep the cold diesel smoke or white smoke and slow to accerate when timed slow enough to live with much fuel you need a way of advancing at low power modes or at idle.If you don't understand what am talking about ask some one with a Vmac that the timing advance has stopped advancing and see what they say.If you was going to be pulling all time then you could retard the timing on a mechanical pump and leave it.

460P Posted December 31, 2014 Share Posted December 31, 2014 One thing about the 350 pistons they have a higher compression ratio than a 400 and higher HP factory engine. So you will be limited on the amount of air you can compress. Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted December 31, 2014 Share Posted December 31, 2014 The hi compression piston will be harder on the head gaskets due to more cyl pressure.The bowl size will be different size on each different compression ratio piston also Quote glenn akers Link to comment Share on other sites More sharing options...
woodhog Posted December 31, 2014 Author Share Posted December 31, 2014 Thanks for the replies I guess that I have some more thinking and research to do before I pull the trigger on the deal Quote Link to comment Share on other sites More sharing options...
Timmyb Posted January 1, 2015 Share Posted January 1, 2015 There was a guy on here who played around with his e7 350 and got great results. If you search these words "new turbo, new aftercooler and pump turned up equals fun" you should be able to find it. Hope that helps. Quote Link to comment Share on other sites More sharing options...
woodhog Posted January 1, 2015 Author Share Posted January 1, 2015 I searched the key words and no results ,maybe some one will chime in on this guy Quote Link to comment Share on other sites More sharing options...
