I've spent so much time over the last 13 years helping to build and tune everyone else's truck, I figure it's probably time for me to get off my butt and put the screws ours. The build process on this truck is going to be a slow, methodical one as I want to quantify and qualify every modification we make as well as come to a determination as to what would be the best order in which to perform the modifications. Hopefully this will provide some very useful information to folks who are considering some modifications and are just not sure where to start. So, let's begin...
The truck we're building is a 2001 F-250, 2 WD, Single Cab Longbed. The truck had 234,000 miles when it was purchased and it currently has 241,00 miles. The only modification on the truck when we purchased it was a Homemade Tymar/6637 filter kit. Other than that, the truck was completely stock. The engine, turbo, HPOP and injectors are all original, and to the best of my knowledge the engine has newer been apart. A new transmission was installed at about 140,000. Incidentals such as water pump, hoses, alternator, or other minor things I'm sure have been replaces as needed, but have no bearing on this project so I'm not worried about them.
The goal is to see what gains are realized from different modifications, what order would be the most logical to perform them, and ultimately how much RELIABLE, STREETABLE
power we can squeeze out of an average, reasonably high mileage vehicle before we experience any significant failure (ie. head gaskets, cracked pistons, or even a *GASP* windowed block). Each level of the build will be dynoed, datalogged, and documented and all information will be publicly available for reference and scrutiny. It is my hope to push 600+ streetable HP and do it for less than $7,500.
The Parts (Initially...):
- Injectors: Ryan Casserly and the rest of the guys at Full Force Diesel will be handling all the injector builds in each stage of the process. It is our plan to start with Stage 1 Singles (160cc/30%), graduate to Stage 2 Singles (160cc/100%), and then settle in on Stage 3 Singles (300cc/200%).
- Turbocharger: Bob Riley at DieselSite will be helping to handle turbo upgrades, from a minor upgrade to a WickedWheel replacement compressor wheel all the way up to a full turbo upgrade when we are ready. Possible choices are GT38 and GT42, but others may be considered in the meantime. Since compounds or parallel twins will undoubtedly put us over budget, we won't consider them unless it becomes absolutely necessary.
- HPOP: DieselSite will again be our choice for all the High Pressure Oil needs. The Adrenaline will be our first stop, and then either a Pulse or OverDrive setup as our demands increase.
- Exhaust: John Anderson at Little Power Shop has already provided us with a full Diamond Eye 4" Exhaust kit, though it hasn't yet been installed. We will be going with a standard Single Out setup due to the fact that our truck has a full top on it and stacks will not be able to be installed.
We will first set a baseline for the truck with Dyno charts and Datalogs. The dyno we're using is a Mustang Dyno Eddy Current load dyno and we will be simulating loads of 7,000 Lbs. (approx. weight of vehicle alone) and 15,000 Lbs. (approx. weight of vehicle with an additional 8,000 Lb. load). We will monitor all pertinents such as MAP, EBP, EOT, EGT, ICP, IPR, SOI, and anything else we feel would be useful. All runs will be made at a stabilized operating temperature (minimum 165ºF for EOT) in order to help maintain data consistency.
All parts will be installed, tuned (if necessary) and tested. When we are comfortable with the configuration, we will then retest and datalog the vehicle. All subsequent performance tests will record the same parameters in the same fashion as the baseline tests. Once we feel we've exhausted the configuration, we'll move on to the next modification. If at any time we should find a deficiency in a particular system, we will resolve that issue before moving forward. For example, if there is a deficiency with the high pressure oil system, we will resolve that issue before moving up to a larger injector. If airflow becomes too big of an issue, then the turbocharger will be addressed.
The central idea is to consider how to possibly build in stages that make the most sense, both from a performance standpoint and a financial standpoint. I've considered the idea of simply installing a 300/200 injector and just detuning it for street use as this would give a person considerable headroom to "build into" down the road as time and finances permit. However, I can still detuned the setup at the end of this exercise and I feel that more usable data can be had by slowly building up with different stage injectors.
Anyway, the project (which technically has already started) officially starts today (11/14/2010) and goes until I top 600 HP or I pop the engine. I know there are a number of gamblers out there, so feel free to pick which you think will come first... Top or Pop. Keep in mind that this is a 240K mile engine and I have ABSOLUTELY NO IDEA
what condition it's in, so don't get all excited if it lets go at 575, 500, or even 450 HP. That's just the way it goes.
I ask that we please keep this thread clear of debris and not take up space with "Hey... what's the status?" or "Did you break it yet?" questions. I'll be happy to respond to legitimate questions about the testing process, the parts used, or the POSTED
results. Anything else will pretty much be ignored.
All parts used will be, or have been, purchased. I am not expecting any handouts and I will keep track of all purchases to not only see if I'm able to meet my goal of 600 HP for $7,500, but also how much each modification costs and how much power can be made for the current amount invested.
I have no plan to incorporate Nitrous, Propane, or Methanol into this project, although I will be considering Water injection only as an exhaust temperature stabilizer. However, I'd rather avoid such consumables if at all possible.
In the event of any significant failure, the test will conclude and all final results will be posted. I have another block to work with, but that will be used for a much more serious build and would not fit the parameters of this test.
I think that's pretty much it. From here on out, I'll post up Dyno Sheets and Datalogs as time permits.
