DDP vs F1 Injectors
#31
Chapter President
I have DDP3's in my 12V. They are lopey at low Rpm tugs off the line, but they smoke way less than my 215's did at cold idle, startup and low level runs around town. I really like them. I considered the 370s, but the reports are always idle haze, stumble at 1500 rpm, loads of smoke so I waited.. If the average joe were to drive the truck without WOT blasts, you would never know it had DDP3's in it. Runs really strong and smooth. They will black out the sun on a good rip, but if you drive decently you can keep up to traffic with just light throttle.

I really want a set of Don's 12v injectors...but he told me I wouldn't like them for my driving style. Said they need a BIG pump to push the fuel to them...and I'm not ready to drop $4K on a pump just to try some injectors. I'm sure they're good...but I'm not that wild for power...yet!
The DDP4's I run have really impressed me for 12v injectors...beats the heck out of my old 370's. BUT, Brandon's (Joefarmer) HotRod 370's run just as good, if not better, and are just as clean on boost!
Now if I could only make enough power to see what they really do!

Thanks for the 12V bumps. Gives me something to think about. I put a set of 5K GS's in last night with a different plate and have a pull this Friday so we'll see how it goes. I really need to get this dyno'd to know where I'm at and where I want to go. Ah, the never ending quest for HP and torque.

What was suppose to be done with the pump?

I have seen Dyno numbers vary 150 HP because of pump tweaks... No way to compare setups, because most people have no clue about pump tuning and buy the stuff that the E-Tuners tell them is the best.

Something doesn't seem right. In this case I would have to say that Jeff Garmon DOES know something about tuning pumps. I've been chasing one of his pumps on a 96 this year pulling and haven't caught it yet. Let us know what he finds when you get it back. Hopefully something simple.

I told him I wanted 700hp, 12.0 seconds, and little smoke once the boost hits...He said no problem.
Exactly, I'm not upset...although I am a bit disappointed in the performance and lack of driveability.
I'm sure he'll get it fixed...but I just haven't had the time to yank it off and send it back down to him. I talked to him at TS and Indy, and he gave me a few things to try...but nothing seemed to help.
We'll see what happens

Don't need to spend $4k on a 913 or 887 pump to make modest power. I bought a new 887 pump last year from an out of business Bosch dealer(still new in box for $1400) and sent it to Ponci's for some minor tweaking. 3k kit, rotate barrels and balance, home made 100 plate. Cost was around 500 for the work and parts. I made 678 with Mach 7's and 739 with some II injectors diesel only. If you were trying for big power it could get expensive, but I think 800 is quite doable with just tuning .

I run a set of Dons HR370s and I can tell you they are nothing like the regular stock marine injectors, these things can put out the fuel and are way cleaner. Harry from Peak Diesel Performance has a sister truck to mine with the exception of the PDR cam in his verses my Helix and he runs a set of Lennys 4s. We both run custom cut Piers plates in 215 pumps with the same DVs and the same PDR tow twins. In a side by side race my truck is way cleaner but Harrys is about 100-150 degrees cooler? We had plans on doing a swap last week to see what differences we would noticed but my HG had other plans so the comparison wont take place for another month or so. I hope to be up and running again by next week and after a few re-torques will be back to the comparison. Feel free to PM me in a month or so and I will be able to give you a true hands on comparison. So far though they both seem to be a good injector.
Forgot to mention Don told me the Mach 4 12V injector = big bottle only
Not sutable for street use.
