who wants a CDFP upgrade?

the CDFP is a must have in my book. anyone who wants to mod should get one ? even if it adds nothing but a "safety net". the most important thing when tunig is having enough fuel to feed the fire . we have THE EXACT SAME PUMP the audi/VW guys have. the stock fuel pump is limited to 200hp @4k RPM.... if you are happy with that, then i guess you dont need one. me, on the other hand.... that simply wont do for me. where did i get this wonderful info you may ask ? it is right on the APR website. this is what they do....fuel pumps, there info is as accurate as its gonna get. the chart speaks for itself.

Yeah, but the stocker is capable of 350 hp at redline on that same chart... Mrlilguy's dynos show that without a bigger turbo the pump is not necessary. Based on the Mrlilguy's results, the difference between stock and upgraded pump is in the noise. Essentially they performed identically. You need a bigger/more efficient turbo to really realize the gains. I should know. I have apr's/cp-e's pump on my car.
 
the pump made little difference...true, but for a reason. mrlilguys car doesnt make enough power for it to matter. i bet on a car with a full TBE that spools up and makes power a lot sooner, it would come into play. that is how the CDFP works, it relies on engine speed to create pressure. so yeah... the stocker can support 350 HP at 7k rpm. does your car make power that high ??? mine sure as hell doesnt ! we need more fuel in the low/mid range. the CDFP gives it to us through the whole range, so it works out just fine. i bet once i get my downpipe on and continue running the 20psi that i have been, it will make a substantial difference.
the reason for the HP looking the same on all the dynos is simple too. i'm sure everyone knows how dynos calculate HP. it really only measures the TQ and then based on the engine RPM it calculates the HP. the problem with the MS3/6 is that the power falls off so damn early. that makes it very hard to have decent PEAK gains. the longer an engine can hold its TQ, the higher the HP will be ALWAYS ! the fact that our car is all midrange kills the HP numbers. from the dynos mrlilguy posted i saw a very noticable gain in midrange TQ in EVERY run with the pump. also if this throttle plate issue ever gets addressed, the stock pump will never be able to keep up until redline. i have seen a few cars hit 290-310HP by 5k rpm. if the car actually held that power to redline they would be 360-375HP cars easily.
just my thought. a good fuel system is the FOUNDATION of building any performance car. it seems like a common sense, must have mod to me.
mine is on the way soon...thanks MRLILGUY !!
 
i guess me and driver had faulty stock pumps? lmao

the reason mr lil guys or dadaracecars pump didnt make a difference is because they are both not making enough power. Simple as that.
for the record. you dont not have to be big turbo to get this pump. i was running out of fuel at 15 psi with i/tbe on cold days.
 
I got a PM the other day from a fellow mazdaspeeder about northmiller blowing up his motor.

from the looks of things, i think he needed more fuel, but maybe thats cause i'm biased :D

funny how his power drop aroudn 4900 is a pretty much where my car was cutting out....ironic but wait he must have had a bad stock fuel pump as well(evil)
 
bahhh humbug..... who needs fuel right !! leaner is faster, thats what i always say ! can you make my stock pump flow less fuel MRLILGUY ???
 
YOU BET NEIL!! In fact, I'll send out a pump, no piston or bore. That way, fuel won't go into the cylinders, it'll flow into the head and down into the pan. Sounds lean to me....

teehehe.
 
You guys are funny. All you guys do is spread this BS about how the upgraded cdfp is going to save the world and prevent engines from blowing and give s*** tons of horsepower for weeks. I argue to the contrary and say that you need a bigger turbo to make use of the pump. I then show dyno proof of it and you make up all kinds of excuses why I'm wrong and that I'm full of s***.
Then mrlilguy is going to do a cdfp swap on the dyno and show the world how everything is better with the pump, blah, blah, blah. He does his dyno thing and lo and behold gets the same answers, i.e. no gains. Nobody mentions a thing.

I come back and point it out and here we go again. Same bulls*** backed up only by "facts" of laloosh's trap speeds and inane youtube videos. LMAO. Jokers.
 
the pump made little difference...true, but for a reason. mrlilguys car doesnt make enough power for it to matter.

From the dynos mrlilguy posted i saw a very noticable gain in midrange TQ in EVERY run with the pump.

Loosh gained 6mph (ran 106mph) from the intake/tbe/17psi which represents how much power over stock on your US dyno's? 70hp give or take meaning roughly 310hp ATW correct?? So therefore what you guys are saying is by adding the pump and 1psi you will gain another 6mph (Loosh quoted 112mph and even higher lately) which would equate to at least another 70hp ATW taking power to nearly 400hp ATW correct?

According to Tru-boost the massive difference in power between lilguy and Loosh is purely down to lilguy using a race pipe vs Loosh with a TBE? So if lilguy puts one in he should see a gain of roughly 80-90hp correct (uhm)?.

Is it possible to see a dyno from Loosh? lilguy's dyno showed no real benefit, i would think Loosh would be the poster boy for this pump yeah?

On the second point, you need to learn to read graphs properly. Spend a few minutes comparing the stock pump power runs between mods. There are major discrepancies between power runs done on stock pumps which make the difference look a lot bigger than it actually is.
 
Driver311 - How about you? You mentioned a few times you were getting on the dyno but nothing came about it. You have the upgraded pump and you said you have unlimited access to a dyno.

So how about it?
 
i have ZERO desire to pay out of my pocket to shut certain people up.

Cough up the money and ill go dyno at the place where darksun dynoed.
i believe it 75 bucks for 3 pulls, dada you can hold all the money if you want lol.

btw out of curosity whats the dyno gonna proove to all of you? i've never dynoed this car so i dont have a baseline. What your going to see is somethign that says 320 and 380, what then? Will that make you happy?

A fair question.
Ill say this first before going into details below (as its fairly lengthy and not all will read it). I feel lilguy or PG should pay for your car to be dynod (showing boost, not A/F), not you. If they dont fork up the US$75 or whatever it is then that to me is a big red flag. If you refuse (which is your right), well what can i say....

What it comes down to is exactly what claims about this pump are true?
We have been led to believe the results from your car is what we will get in our own car. I think everyone can agree thats a fair enough comment.
Per your posts, you gained 6mph so roughly a 70hp gain and can rev to 6500rpm easily. Awesome.

Instead, what we saw was minimal power gain, no holding revs longer than the stock pump, better A/Fs. Pretty much the same results as Dadas which everyone gave him s*** for. There was the excuse that lilguy wasnt modded enough. He was running 2psi more than you but had a race pipe, not TBE. I dont believe for a second that adding a TBE + CDFP will give this car 100hp+ ATW as thats what this person is claiming. The same person that did not accurately compare the graphs.

Ill come straight out with it and say I find it rather interesting that neither PG nor lilguy have paid for Loosh to have his car dynod pre/post pump as your car is the basis for all their claims. It seems they're happy to sell the pump on the pretence that your results is what one should expect but yet won't pay to have it dyno'd? Them failing to do so either means they know they cannot replicate your results or they know something about your car that we don't.

Secondly, other upgraded pump owners have posted they are having their car dynod but then when it comes to posting results theyve conveniently made trips out of town, couldnt do it, forgot, dog ate the dyno etc and we never hear anything again. Lilguy is the only one to have actually posted the dyno results of which he could not replicate the claims.

Believe me I want this pump to work, I want it to do for me what it did for your car. On the other hand Im not a complete idiot, if people want to sell a product it will be subject to scrutiny. If you have a product and make claims that it will do blah blah blah, you also need to provide the evidence that it does what you say it does. Not say to me oh but it feels different when you're on the road...what 100hp different? Come on (encourage Unfortunately Loosh you are stuck in the midst of all this.

This board continually scruitinises CPE, how is this any different?
 
Maybe this is the missing link (laugh)

I'll get dynos up this week. I would have before but as everybody knows.... my pump wasnt in order. So really "the other guys who havent posted dynos" is ...... Driver. Ive spoken with him and I think the cold weather is causing him problems replicating his previous runat 311whp. I know the weather screwed me on my last dyno runs. I only showed 12whp gain, and I added DP, FMIC, 2 psi on the standback, BOV.... but the dyno gave me a 6% CF penalty over my baseline because it was "nice and cold".... which we all know that the car hates. **** dynos really.... I know my car is faster.

Should we start arguing that DPs and boost arent worth the money because they didnt show much on my dynos...lol?

I think before and after dynos are going to be misleading. The ecu has to adjust to this thing a little. I think multiple WOT runs at a track like the day Laloosh got his 111 trap is going to be benefited more with the pump on.

You know what else... dont buy the pump if you dont want it. Just dont.

I had the thing on my car and even with it being ******* out of touch with my ecu.... I could tell a difference. Hell... my neighbor who is a well known Honda driver/ racer could tell a very noticeable difference in my car in boost. It was significant.

BTW.... dada..... I think its a little funny that your alluding that you think Laloosh had a bad pump before. Is it your hypothesis.... that anybody with his setup and a "good stock pump", should be capable of trapping 111? Thats nonsense to me personally.

Again....I'll post my findings this week. Supposed to be great weather, maybe I'll find something more conclusive than mrlilguy.... after all..... Ive got a TBE:) In the meantime... I dont think we should hammer Dada's argument too much. We havent replicated Lalooshs car. Its possible that Dadas right AND Laloosh is right. I dont think the pump will benefit everybody immediately.... but that doesnt mean it wont be very significant for everybody eventually.

Bottom line..... why are these things so hot in the VW world. Its because modded DISI engines need them for power. Simple.

i have offered to front money to dyno for any car running this fuel pump, publically and privately, on and off the forums. i have made this offer several times now and have made it on the pretense that i would help pay for it regardless of the end results.
 
well somebody start a fund and ill go dyno if its what you guys wanna see. today is 62 degree outside and the car is straight out crazy compared these cold temps we had.
 
there will have to be two dynos - one before and one after the fuel pump install - for the results to be at all valid in anyway.
