Do you know what EFR is in generics?


You can already make high 300"s with the stock Turbo.

 

But this turbo spools similar to stock and keeps making hp after 5800rpms where the stocker is dead.

 

On an optimistic dyno with a shitty power band

Power under curve ftw.

 

to be fair those numbers actually aren't that far what what the bnr 2871 was projected to put out .. however no ones gotten any dyno numbers currently so who knows the people who have put regular 2871 on their car have pushed 420+ whp on less then 26 psi

i mean **** look what cams did even on the stock turbo

not that i mean to take away from what you guys are doing at all this will probably flow better and its definitely something i'm keeping in mind as an option

 

Well after 13 pages can we buy just these custom zzp cams. And considering i have full boltons now if I buy this turbo i should be able to bolt it up get tuned and see 400 with no problems at all with out these cams. Just curious becuase im not gonna buy something that im stuck to one company to spend ever penny on to get results. not bashing anyone just saying

 

Should be able to get well over 400hp with this turbo, and without cams.

 

Haven't you seen Matt several times stating that a bone stock car can make 450 on this turbo with ease. It's up to you what else you wanna do with it: ic, pipes, etc... How can you say you'll be stuck on one company when it bolts up to the stock manifold and uses stock boost control and wastegate dump. Let's think a little more here.

You can run whatever other company you so desire for your hot and cold pipes, ic, bov, cams. Why you would run anything other than ZZP is beyond me, but hey, what do I know?

 

well i dont need to have a fully built head just for cams or a fully built block just for rods and so on.. i was gonna order all my parts from zzp but 2 days of trying to get ahold of someone i went with treadstone. only had two minor issues on pieces and solved.. im not one to mix and match parts. if i buy from a company I want everything from them. when you pop my hood it all has the same name. I dont have 2 or 3 different ones. And i paid 500 less and from what ive seen with other people that have the same parts i got no difference in performance. im not a nut swinger or ball buster but people are intitled to their own opinion and the first time i talked to zzp it was clearly put to me that without their parts my car wouldnt be fast. This is just like the ordeal with vince and hp. vince is one person doing more than a entire team of people do. but eveyone bashes vince. I have had a gun pulled on me beat with brass knuckles and all over a damn cobalt and my wife and im really geting tired of the single sided **** on this forum. people dont post half of what they find out on these cars because they get flamed for it or it wont work. but there is a car on 100 % e85 and no issues at all. so thanks for pissing me off with the same ole why would you buy from anyone else. WELL MAYBE MORE THANM ONE COMPNAY MAKES DAMN PARTS

 

Dude your a retard. First of all I don't ever flame and always try and help people. You obviously didn't read anything I said and got all worked up over nothing. I'm not about to start a bitch fest with you, but if you had a gun pulled on you and beat up with brass knuckles i would say it might be time to cut your losses and sell the thing.

You are right everyone is entitled to their own opinion, and I get what your saying about opening your hood and seeing one company. But why aren't you buying everything from treadstone then? And why do you say you don't wanna be stuck on one company when you just told me you only like having one company under your hood?

I'm a zzp fan and supporter, but what your also overlooking here is that the majority of what you might be buying is Borg Warner. So buying this and opening the hood there won't be a huge ZZP logo anywhere if thats what your worried about. it's a BW turbo. ZZP just made it super easy to run, with the option of buying more of their parts for efficiency. You should know what your stock parts are capable of. If won't be slow without supporting mods. Just not at it's full efficiency level. Understand where i'm coming from?

 

iirc the SRT4's have been there for a while...


just saying.

You do realize of course that GM is still interested in selling parts, and servicing their cars outside of warranty right?

abiding by that is just as prudent as waiting for the oil life to hit, or exceed 0%...

agreed.

.... @ John(gmtech16450yz) - thanks for speaking up!

 

True.


And True.

 

I did some more dyno tests yesterday to better judge the spool capability of this new turbo. Here are a couple dyno sheets-

First sheet shows the stock K04 turbo vs. the ZZP EFR hybrid turbo. Both test went wot at 55mph in 4th gear(4.45 final drive). Notice that the spool is identical. both were set to the same boost level, which the stock turbo was not able to maintain. Disregard the "average hp" line on this test because the K04 test wasn't set to record data until 60mph, while the efr test was recording from the start at 55mph. The first 5mph without boost totally kills the average power number. If you look between the curves from 4000rpm and up, you can immediately see a HUGE difference!


Next, to determine just how low in the RPM band the new turbo can spool, I went full throttle at 30mph in 4th gear.(1500 RPM) This resulted in 20psi boost at 2950 rpm!

 

Holy **** *****

 

Wow, that is awesome. It looks like the EFR series is living up to the hype.

 

when will you have these kits ready for sale Matt? I think my turbo is dieing.

 

That's the excuse I plan on pitching to my GF when the time comes

 

Thats a really good spool. I think my stocker spools at like 2600

 

how much will it cost

 

I think that's what were all dying to know

Matt somewhat answered my question a few pages back.....it's a long process and don't expect the thing to be ready in May

That's what I was hoping but quickly got my hopes up annnd then shattered

 

Well I have money burning a hole in the pocket for the first time..


PLEASE have this by June !!!!!

( Doing full build )

 

It doesn't matter. Here is whats going to happen. People are now saying "We're gunna buy this! Yeah woo!" A few months down the line, when this comes out, guess what...cold feet are going to appear and people aren't going to follow through with what they say. There are do'ers and there are 'talkers'. MANY people just talk. :P

A HUGE portion of the ss community won't be doing this, will be staying on stock turbo, or getting another car. :P Those who want to drop the cash on these cars, have invested interest in them, etc are EASILY outweighed by the few who are.

The EFRs are revolutionary turbos for the most part. These small turbos make alot of HP!

Patience is a virtue. Good things come to those who wait.






Great stuff Matt! You guys do it again!

I'll see you all very soon.

 

Damn I didnt expect them to spool that closely lol.

 

wish i would have known this was in the works before i did my 5857 build oh well. great work ZZP!!!!

 

Thats unbelieveable how it spools! The power curve just traces the stock one and keeps going where the stock one dies off! Surprised your clutch didnt tell you to eff off lol

 

lol, zzp stage 4. (Not even stage 4 plus.) It holds 550 ft lbs without the slightest hint of slippage.
