Who stuck them barrels n plungers in for U?

Well...Myna is of course good, but Tomniks Elements + DervTuning is another option on the STD forum. However, Derv has not been on in a while. His pump had great results, but it is a time situation most likely. Derv is in Maine so the cost should be much less than MynaDiesel!

err... I gave all the pieces from the 606 back to him. LOL!!! Have to ask him about that

We can talk about what we need to build another. I have parts to build three right now but one is going to be mine. Need one to get running before we tune another... GSXR! GSXR!! GSXR!!! Woot! Woot!

I am going to follow him because, well not only am I lazy, but he has so much experience. I would just get lost in minutia spawning out of my lack of experience.

GSXR --is a pump builder?

no he is a guinea pig The pumps were built by a Bosch shop for us.

Any shop that will handle a benz M or MW would be nice to know of.

Derv tuning seems to be a no -go deal because of communication problems.-sides i thought they were in murder city.

Pacific fuel injection seems to be a go deal on the west side.

Cart before horse but we can build more. The pump GSXR is going to install looks great on a test bench but a bench is not a car. Wait till we see it running and then we can talk about building more.

I am in the same boat...I have an HX35 and Euro manifold that I am itching to install onto my stock 603 to see how it will do before a pump. Then I am going to run a 3" straight pipe, intercool, and get pump tuned.

Cool. I can quote a price to build more once we know they work but I have a "real" job that is pretty demanding. You know gsxr will report on how his goes because he is "da man"

Same can be done for a 602 of course.

He is the man, I wonder if the 7.5 Floyd elements would be better. I also wonder if maybe there would be someway to fabricate an adjustment of some sort. I have a guy that could fab the parts.

I hope to have it installed & running by the end of this year. First up is (another) baseline dyno with the rebuilt stock pump currently in the car, then I can swap pumps. The big question is, can the stock turbo & manifolds flow enough air to feed the 50% fuel increase. I think it might... but I should know soon.


That was a 606 IP that I supplied to Kurt for his shop to swipe the 6mm elements out of. I still have it, but in pieces (all neatly bagged for re-assembly). If anyone is interested in buying it, drop me a line. The guy I was saving it for recently let me know he no longer needed it. D'oh!


Oink, oink! (Or more accurately, "Squeak, squeak!") Even if the airflow is adequate and power output is good, I'm a bit concerned about my transmission holding up with 310kmi on the clock. At least I have a spare, but ugh, I'd rather not have to go there.


Agree 100%. I'll feel a lot better about recommending this mod after I spend some time driving it. If all works well, a dyno run will back it up as well - no butt dynos or bench racing, I will have actual data. I've already got 0-100mph data (from a RaceTech AP-22) with a stock pump and stock pump maxed out, so I can also compare to the 6mm maxed-out pump after it's installed & running.


Yup, and Casey is seriously contemplating this on his 602. He already bought a core pump. If all goes well, he may have that built with 6mm elements relatively soon. Should be good for +50% on a 602, or 170-180hp at the crank.


Well, 7.5mm elements would push more fuel, but if you don't have the matching airflow... that doesn't help. Also, 7.5mm elements ain't cheap. I had the 6mm elements on the shelf in the 606 pump (purchased a few years ago) so it was "no cost" for the elements.

My plan is to test the 6mm setup and if it works well, drive it for a while while saving up for a 7.5mm build. I don't think I'd attempt the 7.5mm pump install without also bolting on a larger turbocharger along with an intercooler; as those elements should be good for nearly +100% power increase (150hp --> 300hp). I'd be happy with 275-300hp at the crank (230-240hp at the wheels, same as my E420). At the moment I've lost interest in Myna's mods with 7mm elements, based on the anecdotes that they don't idle as smooth or quietly as either stock or "Floyd" elements. I don't need 450-600hp so the Floyds should theoretically be ideal for my needs.

We have the same mindset Dave! I am excited to see your results. Also, I should have a couple good 603 IP cores soon for such projects. Like I said, I am already ready to put in a larger!

Turbo?

I have one like New unit without the 12 volt controller for 5 Benjy's

Do you guys got it goin your way?
