All these talks about 60-100 times make me curious what this cars time would be...... hmmmmm

Maybe you could ask your dad.

Na, he wont push it to 100 That photo was taking on the only drive it has had in July I believe. A 15 mile jaunt. Really piling up the miles!

Nice Job Mr. Elff, pretty close to the same numbers as the EFR.

Sorry Dave, but the BNR numbers are nowhere near EFR numbers. Maybe for a sharp spike they're within 50 or so, but the overall power spread is WAY different. Down low and up high there's as much as 100 hp/tq difference. My EFR build is AVERAGING over 400whp and 400wtq from 3500 to 7500rpms. That's a 4k power spread. (For those quoting high dyno numbers, do this- add up all the values over your powerband, say every 500rpm. Divide them by the number of values you added up and see what the average power is. You might be surprised at how low the average is. Peak numbers are meaningless.) That's what gives 60-100 times in the 3.2 to 3.6 second range. These screen shots are from this morning. The 60-100 was a slow (for my car) 3.89 seconds because it was UP A VERY STEEP ONRAMP. I usually do 3.4 seconds pretty consistently on flat ground. I calculated the 63-92 (should be 62-93?) the same as Elff and got this 2.48 time. That means my 100-150km/h should be more like 2.2 or 2.3 on flat ground.

I know the supply issues of the EFR, and it sucks big time. But you can't say they aren't amazing turbos. These screen shots are way zoomed in and my boost line still goes straight up. It's putting out 26psi BEFORE the throttle plate is even at 100%. At normal zoom level, my boost reading is a vertical line when I go full throttle, and I'm not even commanding 100% wastegate duty cycle at that point. Meaning 0 to 30psi takes less than a second on the EFR. I've never seen any other turbo spool like that.

For those of you wondering why I'm here or why I'm back, I'm asking myself the same question. lol.

[Critterman]

You like abuse?  Doesn't matter, what is important you are back.

The Asylum needs more inmates.  Please hang around !!

We found out where the EFRs have gone,  Apparently Unicorns are actually Indy Race cars.  Werks figured this out. 

My times were on the first E47 tune my car received and this was from the first batch of logs.  Cool thing is NO FUELING ISSUES!!
I already have a tweaked tune from Skynet [That's a Terminator Joke]
So we are hoping to get my time down to under 4.0 seconds, which for the 2871 is no Joke.   I'm very happy with my little turbo and with E47 it purrs like a cat, but smells very non car like. 

I do have you beat in one thing.
I didn't need to use a calculator to figure out my time   
 

Good to see you on here.   Please keep coming back.

while you are here, check out 40rty's Dyno Thread.

Mr.Tech

Sorry, I should have said "Nice Job Mr. Elff, pretty close to the same time as the EFR from the original poster, not all EFR's in general, especially the EFR of gmtech16450yz"

original poster 100-150 - listed as 3.09
Elff time 100-150 - listed as 3.292

I just thought it was pretty good that both cars running on E47 had pretty similar times, that is all. I did not mean in anyway to imply to anyone that the 2871 upgrade has the same power potential as the EFR 6758, anyone that sees the turbo's next to each other can see that. All that being said though, Elff's times are very close to the original poster (not yours, not jeb's, etc) and our latest dyno's on the new 2871's have us averaging over 350hp from 4-7000KRPM with peaks of 375hp and over 400 torque and they only take a couple days to get

Nice job with the EFR though! You still running E85 on that?

[Arabas]

welcome back gmtech!!

can you also calculate and post the same 100-150km/h in 4th gear with your set up?

[ihawk95]

I understood you meant time Dave.

Dang nice times Boys! You're right elff...corn is good!

[LatinVenom]

Can someone comment as to why the ve is 34 for Ellf and 38 for GMTECH.
I thought the 2871 was capable of over 40lbs and the EFR 6758 well over 48 lbs.

[elff]

Are you confusing that with the MAF?

[LatinVenom]

NO, remember Shabby when he was messing around with his tune and change some tables that got him close to 30 psi.
I thought he posted a ve for his KO4 of 34 or 36.
Maybe I am remembering things wrong and Shabby can correct me.

[Kelu]

Are gypsies illegal aliens?

All these talks about 60-100 times make me curious what this cars time would be...... hmmmmm

Get HPTuners and measure it, you might have a surprise

My EFR build is AVERAGING over 400whp and 400wtq from 3500 to 7500rpms.

Welcome back John, one small difference between YOUR setup and elffs?
You have a complete rebuild engine with upgraded internals, upgraded head, one year of fine tune and some others? Doesn't that matter at all at least to be mentioned?

Please stop being so defense, nobody was aiming you and majority here are more mature than you think and can appreciate other's successes.

Your memory is good but airflow numbers can mean nothing if they are not properly "calibrated". With big turbo I was doing same amount of boost & timing & airflow but only 360hp and now I do over 400hp.

[miller11386]

I have HPT Mr Kelu.. the issue is getting it on the road and convincing the driver to actually put the hammer down!

and the surprise would be driving it and keeping it out of the ditch!

[Kelu]

Mr. Chris, I know you have HPT but than you are two in one:

- unable to fulfill your wishes

- bad driver if you can't keep a vette on a road

PS: just teasing to make you try harder and test that sweet vette to have a nice comparo

[miller11386]

i almost have my in. the clutch pack in the diff isnt wanting to let go, so perhaps i will have to take it up to the garage to look at that

HPT will be in tow if that happens haha.

[elff]

Can you also calculate and post the same 100-150km/h in 4th gear with your set up?

Arabas

Why are you so interested in a 4th gear Pull vs the 3rd gear pulls as displayed?
Is there some weird unwritten Greek Street racing rule that prohibits the use of 3rd gear.
Please don't tell me you guys use Solo rules for street racing

[Arabas]

elff, i m not asking for this only for racing purposes. a 100-150 pull in 4th gear also shows how the engine responds to high speed at low rpms. this is mainly for street use, when you want to accelerate (i.e. overpass) and from 5th gear go to 4th.
in real life driving (not racing) being in 4th gear at 100-130km/h is much more realistic than in being in 3rd gear, except if you are looking into cleaning your valves...

[Gentleman Jack]

I clean my valves 3-4 times a week.

[elff]

Arabas

If I am at 60mph, and I want to accelerate quickly with a purpose, I will downshift to 3rd vs leaving it in 4th.  It's more optimal
IMHO, There is no point in attempting to pass in an RPM less then 3000 rpms or when you are in a range that has you out of boost, because you waste time and gas in too high a gear waiting to get to the power band. 
I consider that real life driving vs racing.

FYI- our cars are Direct Injection.  You are not cleaning your valves in higher RPMS.  That's a downside to our cars. 

[Arabas]

elff, i don't know how to put it in english terms.
it s called elasticity of the engine in Greek.
and it is a standard measurement in the auto world, it's not something i came up with. you measure a given acceleration at 3rd and 4th gear (or 4th and 5th and so on).
i.e. overpassing a truck on the freeway from the left lane and downshift from 5th to 4th. you want to do it quickly, but don;t want to do it racing style, so you don't go to 3rd from 5th, you go to 4th gear.
plus i would like to know how is the engine response in lower rpms, coz in 3rd and 100km/h, it is our engines happy time (at leaste with my given set up)

[Brazen17]

I can't participate,  the legal speed limit here is 70.  I never break the rules.

I think it's your integrity I respect the most...

[Brazen17]

...I meant suspect   

[Kelu]

Arabas is on stock turbo and low rpms (3000rpm) is preferred, elff is on bigger turbo and preferably to use around 5000rpm.

I don't see a different reason.

[elff]

I understand what you are saying.
I don't shift based on speed, I shift based on RPMs and I put the car the proper gear to put it in the power band without over revving it.    In non aggressive driving, I think I put my car into 4th gear at 65mph.  That's just under 5000 rpms.   
Next time I am out logging, I will do a 4th gear pull for you.

I think it's your integrity I respect the most...
