I am doing a stock shortblock 6.0 (lq4) turbo and was just wondering what some of you guys are seeing as far as "reliable HP". We all know that there are alot of factors that come into the hp but given the tune is "safe" and your not detonating.. what sort of power have you guys seen and/or made? How long?

I want this engine to last and dont want to push it to a point where its unsafe. Also while at this power level, how much total timing are you guys running under full boost generaly on pump gas? Also turbo size (mm) and boost levels to acheive these power goals would be appricated too because I plan on street tuning this thing and am wondering if I should get it on a dyno. I dont want to make to much power and obviously street tuning you wont know how far your pushing it.

Thanks in advance

 

They will hold 10 sec power @5000lbs for a few months if tune is spot on. The 05 up will probably last a bit longer. I would say mid with a good tune mid 11's in a 5000lb truck or low 11's in a 4500lb should be reliable. Push it more and your taking a gamble. I use 1/4 mile times times for reference because chassis dynos will vary.

 

Thanks for the reply, does anyone else have any experience with this? I forgot to mention this will be in my 2900lb mustang.

 

Anyone know a good site to maybe get some info on this subject?

 

Huh? This is probably the best site to learn of the potential HP/TQ output and failure limites of the 6.0


Have you tried a simple search? What is it you want to know?

500hp. There that's it

Is this a joke? lol.. I guess making a thread with several questions doesnt inform you on what it is I need to know?

I had the same thoughts you do on this being a good place to get info but, I havnt gotten a reply yet.

Yes I tried a "simple" search. I got some good info that way.. just wanted first hand exepriences in one place.

 

Thanks!

 

500hp for a LQ4 or LQ6 should be dependable and live long with spot on tuning. 600hp is where you start crossing into shakey territory. We have had at least three 6.0 failures on this board in the last month, shouldn't be hard to find.
