Hey all, I have a 95 f250 I bought off a buddy a few years back and I have started really working at getting this truck all fixed up. Just finished installing a Dana 60 and sd springs. Did gauges, a php hydra, dp, and 160/30 injectors. I am almost done with my e fuel setup(what can be done off the truck). Now I am collecting materials for an intercooler and turbo upgrade when I get under the hood for the rest of the efuel install.
I am starting this thread mainly to journal my experience trying see if I can get this turbo(holset he351ve) running on my truck. I want to see if I can harness the drivability of a VGT in my OBS. Quite a few guys with older cummins have been able to get these working quite well without a computerized controller. I will post up what I figure out along the way
Also I could really use some help from anyone out there that's is good with turbo sizing. I am in need of some input from those more knowledgeable than I when it comes to turbo sizing/efficiency. The goal for this truck is a
300+ rwhp meant to run efficient, tow heavy(~15k) with low egt and no smoke. I also want it to drive nice around town and have much better low end response than what I am experiencing now. I have studied the hx40 compressor map for this turbo and I think this compressor should flow plenty for my use. That is, I think. If anyone could confirm this I would appreciate it very much. I have been pouring over info and equations on turbos and engines but am not sure where my HP target fits into everything. The only formulas I have found just deal with total mass of air going through the motor for a given displacement at a given absolute pressure minus ve. Anyways, I am pretty sure I am getting a grasp on this stuff but cant find a formula that tells me how much boost I need to meet my HP goals........ Anyways, I am sure there are plenty of 7.3 gurus that can just look at this turbo map for 2 seconds and tell me if it will get me to my power goals and be running in its most efficient islands.
Now I know many are just going to want to tell me about my t4 options and the d66. I know plenty about all of those choices but for me the fab work involved in getting any turbo out there mounted and plumbed is not an issue for me. I am a skilled welder/fabricator and pipe fitter. I was going to get a 38r and install it but it is almost as much work/parts/fabrication to put on an obs as any other turbo.
I want to do something custom with all of my piping no matter what, I like building things myself and take great pride in what I build. Also I do 99% of my non-tow driving down low in the rpms so I want this truck to run much better down there.
Any input on the remainder of this build would be very much appreciated, especially input in regard to how well this charger will feed my engine at my power goals. I am not too concerned about the amount of hard work will go into getting the thing installed. Just if it will breath right. I have a call into my programmer to ask about programming but can't expect him to hold my hand with everything else.
Thank you in advance,
Noah
P.S. Hopefully as I go some useful info to others will accumulate in this thread. I know that I would not have been successful with many past projects without web forums. Since there is almost no info on the web for the holset ve series of turbos being adapted to fords, I figure I better start giving back!
P.S.S. So I am so long winded & I will start getting some pics in here asap.
God Bless
