I like this attitude… means you’re looking to squeeze more out… rather than “these cars were not made for the strip” lol or see my 60-130.
So an epl/amd tuned 770 car is a 12 second car at 128 and their stage 3 car can’t even make it in to the 12s…then a Jfonz 770 car makes 2 passes and both in the 11s
Anyone one else starting to see a pattern is going to emerge soon lol
Good job though Josh
who knows…we’ll soon hear that these cars aren’t made for the dragstrip from epl
anyway this is a great thing for jfonz

BOOM!
At 6 bar eh? I’m liking that. Are the pumps inline or parallel? Stock fuel plumbing otherwise?
I think that a bigger exhaust can really help and if I rember correctly (and i could be wrong) but dosnt a single 3.5 inch flow more than dual 2.5 inch pipes. I know that my brother pickud up 50 awhp by going to a bigger exhaust from a dual 2.25 or 2.5 inch exhaust…at least what i remember!
Great work tho JfonzwithObsceureness!!! That is what I am talkin about!
pumps are parallel stock plumbing otherwise.
probly be at 7 bar after we add in the rest of the boost.
a single 3.5" should be ~8.94 sq inches
a dual 2.5" should be ~8.86 sq inches
the dual will have more wall friction
the single 3.5" should have less pressure loss, and should flow better and make more power as long as the motor is moving enough air to utilize the flow
Me personally I don’t care who tunes the car, I just like the fact a Tial car doing what it did!
it’s great to see the B5 S4 do well , in my opinion. I like seeing Audis kick some ass.
I find the tuner issue a pretty funny part of the story…and the AMD/Tial guys who go back and re-read my posts on this subject will see that this is what I was getting at from day one.
Nice, doing my research for me, I like it 
I didn’t necessarily expect the 770’s to NEED that much pressure through 044’s in parallel on EV14 1000cc’s. Do you guys have a fuel pressure gauge hooked up so that you can see if/when it’s dropping pressure?
Thanks guys.
I don’t think we are gonna even look at exhaust modification till we get this intercooler thing under control. That is our bottleneck right now.
the gauge is hooked up but under the hood lol. I usually notice it in the logs or tony will see it on the wideband which drives us to add the pressure and check the gauge. We have run this setup on just one pump and started to go a little lean vs running 2 pumps.
anyone ever measure the pressure drop through the ebay intercooler cores?

Cool. I’ve got something in the works that may be useful to you or other client’s cars in the future (you probably won’t want to put the time/effort into switching the fueling setup you already have on that 770 car), that will likely alleviate any fueling issues you are currently having. Your fueling bottleneck is likely either the lines or the injectors, as two 044’s in parallel should be able to flow well over what a 770 car can make on E85 (I’m leaning towards the lines; after I looked at the feed line, I was pretty shocked at how much power people have gotten out of these stock fuel feed lines). Where do you have the pumps mounted? Surge tank? What are you using for a lifter pump in the stock tank? And are you sure you’re not getting parallel mixed up with in a series (series being the pumps are ‘in-line’ with each other)?
I’m curious about that as well. I haven’t seen anyone who has tested them and shown concrete data, but there are numerous cars that are able to make more boost when swapping the janky ebay core out. I personally don’t doubt it’s a restriction, but I’m curious as to what the specifics might be (if someone has already done it).
They have liseted on their spec sheet a 5 psi drop @35psi.
I’d be interested to see how bad it really is.
@jibber,
shoot me a pm about your fueling suggestions/setup
My first thought when we were going lean on one pump was fuel lines and or fuel rail.
pumps are definately in parallel off a surge tank… can’t remember if it’s a stock lift pump or 044… I have two cars that are very similar that i’m working with right now.
Where is the surge tank located? And you’re not hitting those number on just the stock Hitachi MAF and huge housing are you? Just curious to see how others are tackling the same thing.
As for the fueling setup, it’s a product, but I’ll let you know when it’s done, and you can let me know if you’re interested.
surge tank is in the trunk.
95mm hitatchi sensor
we thought about switching but haven’t needed to yet.
idle is not that bad at all.
Dual 2.5 in exhaust will not cut it. He needs a better exhaust setup maybe like mine 4" single 
how does a 4" single sound?
