It will take some effort to get rid of the Dip. (might be able to get tuned out) I am happy with my 4.4 sec 60-100's. More research won't hurt anyone.

 

I know you aren't trying to pick a fight with me now... Im talking about the 2871 that SOMEBODY ELSE tuned and posted, which matches the graph from a totally different person's car and separate tuner yet again. We all can't use Excel Spreadsheets to make hopeful graphs, no everyone buys that crap

 

all what money? all what work? i spend 500 bux on the turbo setup probably 1200 total including piping and **** .. explain how thats alot of money to double the hp of a car lol and again doubling the hp of a car whatever man.. troll all you want.. and i'm keeping up with lightly modded ss/tc's not lightly modded ss/scs your gonna need a tvs to keep up with me .. and even then .. i'm still gonna kill ya on low end.. both of those are quicker then alot of other things in our cars competition without alot of work .. i have no urge to have over 370 whp.. this car is my DD .. i dont want to run around at DR's all the time or replacing tires ever 3 months. i know it might be hard for you but use your head

and i love how you keep jumping to other points when i diffuse whatever you previously said..

 

Looking at the graphs it looks like its the evil K04 counterpart kicking in:

BNRGT2860 PBAss's car

 

Not starting a fight lol. I changed my post BTW. There aren't many of these 2871's out there and not many dyno sheets. All these cars are on stock heads, stock cams. Could there be valve's floating? Maybe a good set of springs and retainers would be a solution for the dip.

 

As soon as you ship me mine I can install, tune and dyno and we will know since I just installed stronger valve springs

 

What are you, communist or something? Trying to impose your ideals on what YOU think others should do with THEIR investment! lol Take your koolaide somewhere else.

Not everyone wants to make that much horsepower that the EFR and 252 can make man. Not to mention that you have to replace pretty much everything weve already bought for our cars to run them in the first place. The people in this thread are looking for a simple bolt on solution that provides some nice gains at a decent price. Not pay 2500-4000 for a whole new turbo kit for the LNF.

Youve expressed your opinion and ppl in this thread have disagreed because their goals are not YOUR goals so please, stop posting if you dont have anything constructive to add.

 

Getting all the groupies to post negative. What class!

 

Its not his education its the fact that his title says he has an 2007. So he doesn't know about the LNF and our fueling issues. The LSJ is different, I don't think this WSox guy hasn't taken any of that into account.

 

I'm saying it is not 75whp more.

 

You are completely mis-understanding the 100hp claim. It clearly states that it comes from the head, cams, and tune.(raised boost) Why are you thinking that it means something different? You are trying to compare with a car that already has a tune.(raised boost)

 

well by that logic the BNR is good for a 150WHP gain easy then. (from raised boost pressure, and bolt ons)

 

you dont think ported head cams and such and a little more boost could pull out 25 more whp? i'm not doubting you i'm just curious because it seems like it should be able to you guys pulled like 30 whp out of the stock turbo with the head and cams didn't you ?

 

LOL
Yeah if your starting point is stock WHP then going from the 230-240s to 390whp with the 2871 is about 150whp upgrade

 

Don't you have the highest WHP K04 Hybrid turbocharger for the LNF ?

 

Yea but that is why drew wants to compare his car to another fully bolted up cobalt. He want to see how much more power is coming just from the turbo. Which is more information that just saying well compared to a stock cobalt its XXXwhp gain... There are other ways to make that hp, this is comparing the turbo to another modified cobalt... or am I mistaken in your intention drew?

 

Then don't buy it and move on with your K04 tuning, easy solution.

You can see in the graphs the stock K04 dips also, one could make the arguement its something else besides the turbo's causing these dips.

 

Drew has already alluded to the fact that E47 is comparable to 93 Octane, so only variable would be bolt on's and tuning solutions.

Since he tuned the BNR 2871 on a E-blend E47.

 

The actual octane rating of E85 is 94-95 Oct (+/-) this is from a wiki article:

"E85 has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts. The Renewable Fuels Foundation states in its Changes in Gasoline IV manual, "There is no requirement to post octane on an E85 dispenser. If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual-octane engine tests."

So E47 is close to 93 Oct. Just gives greater knock resistance. We need it here in AZ because the best we have is 91 Oct.

I guess I do since I am the only one posting numbers.

 

To be honest I almost wish you wouldn't make the BNR 2871 any more for the Delta platform.

Those who chose to jump on board get a great upgrade, those who didn't can spend over $2k + for a upgrade to the stock K04 from someone else.

Yes I know from a business stand point, its not good business, you got to make money, and you have a good product.

But its got to **** you off to no end that someone posts mustang dyno results (and results of other performance cars that day to compare) and everyone still says the turbo isn't good.

But it wouldn't hurt my feelings one bit to be honest if no one but existing customers had the BNR 2871.

Maybe make a few extra for the other Alabama LNF people that supported you all this time for when they get ready to upgrade

 

I would like the exclusitivity

Honestly though you would think people would just be happy with the numbers and give props where its due. Its hard for a hobbyist like myself to post numbers anywhere near what a shop dedicated to tuning and development of these cars. I am not going to rag on someone because they make less power than me. Synapse didn't get this kind of crap when they came out with the 2871 stage III. And they only dyno'd 380ish with their shop car. And the S20G from hahn, when that came out the results were very dissapointing. I post a 393WHP mustang dyno chart from a hybrid K04, and all of a sudden the product is **** because there is more power potential from a giant turbo that you have to buy in a kit.

Yes, and when the turbo is for sale with a tune and the additional mods, it would be fully reasonable to state that buying those parts can add 150whp to a stock LNF. However, that is not at all what I was talking about. I clearly said that the max potential of the 2871 is not 75whp more than the max potential of the K04.

 

Whos 'everyone'? lol Ive only seen one negative comment about the 2871 after drewbroo posted his results. Maybe I missed another.

As far as octane goes well, read what drew said, rating on a blend is about 96 on E85+93 which is what I do plus it provides better KR resistance than 91 alone allowing you to add more timing. Most ppl on 91 or 93 alone are maxing timing out at about 17 before they get KR whereas a blend car can run 21 easy. Thats why I said 360-70 on 93 and 390+ on the blend. I may be wrong.

 

You are completely missing it. BYT said that we made the same type of claim because we said our ported head, cams, tune combo can add 100hp. This was not at all a reasonable comparison, because the combo that he was comparing to automatically comes with those additional components. It didn't say that the head adds 100hp. It didn't say that the cams add 100hp. It clearly stated that the head, cams, and tune together combine for up a 100hp gain.

 

Unfortunately, it would only add about 10-20whp because the ECM would keep the boost the same as stock and it doesn't come with the other bolt-ons.
