Boosting a 2.9 engine has nothing to do with boosting a 4.0 engine. That is total apples to oranges and I really hope that is not your reasoning for thinking the stock 4.0 can take that amount of boost. That is like me saying, "Well the 4.6 DOHC Cobra motor from the 03-04's can handle 700+ hp so I think a 4.6 SOHC in the GT's can too" which would be ludicrous reasoning to think that an engine can take a given amount of boost in stock form. 10 psi is about all I would go on the stocker bottom end of those engines. Maybe pushing it to 12 psi max while spraying meth on track days with a ROCK SOLID tune.
I suggest you state things more clearly so that you keep from confusing anyone with your wording.
If you have a boost referenced FPR then why the heck do you have an FMU? If you want more fuel then command your Lambda in the base fuel table and dial it in with the MAF transfer function in your tune. You may not have a fuel issue yet, but if you rely upon the FMU instead of proper tuning to get your truck dialed in then I expect you to have more than just fuel issues soon too.
Just because it is not your first time doing a turbo on a vehicle doesn't mean that you actually know what you are doing. Knowledge and experience are two different things....Knowledge+experience and actual understanding is a totally different ballgame in itself. It is nice that you own those cars but once again that does not really mean crap either. I know of hundreds of people with 8,9, 10 second cars that do not know a damn thing about anything; usually because their buddies did the hard stuff while they watched. State the issues and discuss them, do not come in here and pull your whole...."Well I had a car on Pinks so I must know what I am talking about" bs. I made a few observations of some things that I feel are likely not right with your project vehicle. Discuss it in a relevant manner instead of saying childish comments such as "and put where the sun don't shine" That will not get you far here.
To start off with the reason I said about the 2.9 is due to the fact that the 4.0 is so much more durrable than the 2.9 liter, and Im was stating a fact of what I did with the 2.9. As far as the 10 lbs of boost goes. Everyone has their own opinion about something. Ok,, then maybe keep your comments to yourself until you actually do a forced induction 4.0 L motor you don't have nothing to stand on. But your guessing and think I know it all attitude. Unless you have some proof to back it up . Otherwise who cares. I mean all your vast knowledge you say you have. .Then why aren't you here making all these turbo kits and selling them since you are "God of the turbo section"?
Im not sitting here ragging on your truck running 20lbs of boost on a regular 4.6 L. I don't care what you have you can do what you want . I didnt mislead anybody in my post, you just took it the wrong way. I was very clear on my explanation. Your just to quick to judge and make adverse comments on something you say you have knowledge on. What experience and knowledge do you have to back up your claims?? I have the FMU on the engine as a back up, I do not have an after the market stand alone fuel injection system that I can just hook my laptop up toand change the peramiters I am not relying on the FMU for proper tuning of my truck. Like I stated in my last post aparently you are not reading it correctly.
or maybe you really don't understand it . My Air Fuel Ratio is 11.7. For your information! I have been working as a technition atleast 25 years and I have built and tuned all of my vehicles ,freinds and customers. Plenty of long term
research and knowledge. I am not the type of person that you are stating that I stand around and watch people work on my cars, so don't be so quick to think you are better then anyone else and make judgement calls when you have no Idea of who I am and where I came from. You have allot of nerve sitting here making those acusations. Maybe you do that. But I don't care.
This is such imature crap and I am too busy to waste time on little things like
this. Oh and the mention about the car on Pinks was a referance not to rub it into anybodys face. I would agree that there are some idiots on pinks, but thats my opinion. and really who cares if you go and have a blast and the experience is something not everyone has had.. But Im not bashing either. You said that in a quote of your comment "You get what you pay for" so how can you fortell that my kit is junk, when you havn't even seen my kit in person. You stress facts here but yet, you are judgeing people without
facts. You make no sense! don't be so quick to jump on my case, My kits
are not expensive because for one, Im not greedy, and two there is no over
head. So why not,, get volume verses high cost and you can do well for yourself with out breaking the bank for other people. I Have had no problems
with people saving money and getting Exactly what they wanted. These people are no Idiots . You are insulting there Intelegence. Also I stated in my old post if anybody has any questions at all (questions not bashes ) let me know! This is the end of my conversation between you and I.
