Good deal. What motor oil are you using for break-in?

I think just castrol 10w-40 non sythetic.

Got the p0140 again already, glad I have a tactrix now so I can clear it. I'll have shane disable it during the tune.

Very nice, A lot of people say that they don't seem to dyno more power with the extra compression, but the butt dyno loves it.

No replacement for displacement!!!

Feel free to stop by anytime if you get bored.

Washed the car today, I need a good camera, the iphone doesn't cut it. But the car just looked good from here, I felt the need to take a pic.

Shit's tits-a-poppin', son!

**Murlo26** · 09-21-2011

Got just under 300 miles on the car now, it feels great so far! After about 100 miles the engine started to feel like it tightened up or something, hard to explain, I think its a good thing

I did dozens of vacuum pulls so I should be good on that front...tune is a coming soon.

**Kracka** · 09-21-2011

How's the EF4 so far? Feel responsive?

**Murlo26** · 09-21-2011

It's tough to say for sure for two reasons.

1. I haven't gone over like 3, maybe 4psi.
2. The new motor is totally different from the old one, 10% more displacement and compression.

But initial impressions are very good, meaning I think this thing even with the tubular mani and being a bigger turbo will spool pretty damn quick. It feels peppy for sure. Before I didn't feel much around 3k rpms, now it wants to spool around there on the new setup.

I am hoping for full boost around 4k, but we will see.

turbotalon1g · 09-21-2011

I don't know if you will get "full boost" by 4000, I know the EF2 would, but also depends on boost and such. Good luck. Let me know how the tunage goes.

remember this is a 10 not an 8/9.

My black hit 36-37psi by 4200rpms on DB's dyno last time on my 2.0L.

With an extra 10% displacement it should be another 400rpms or so lower on the EF4 I would think.

The EF4 is a bit bigger so it could be more like 4200-4400rpms but I wouldn't think over 4500rpms on the setup, we will see. I am also not boosting high 30's this time, so that is another factor.

Andrew is getting full boost from his EF3 with a 2.3L faster than a 2.0L spools a Green.

ah yes, i forgot sorry.

That is nuts on the black.

Yea it was some damn good spool. I would've given up some spool for more top end though, which was why I got a tubular mani.

Here is the boost plot fyi.

turbotalon1g · 09-22-2011

Sounds like I should get a 10 and join the cool kids.

**Murlo26** · 09-22-2011

Here is where we ended today...it broke up ignition wise up top but then we had oil everywhere. My shop is thinking a line, fitting or maybe worst case scenario the crank seal. Basically something on the timing cover side, which is like everything, appears to have leaked oil onto the belts which flung oil all over. Car is still running good though and they need to get it all cleaned up and find the leak. Hopefully I have it back next week.

We took it easy for the most part on the tune (don't need a repeat repeat). I think 6 degrees of timing at peak torque and 15 or so up top. The WGA seems to be a weak point here, it remind me of the FP 18psi. So I will be talking with MAP about that.

The turbo flows very well and can spool very well. We had to dial spool back A LOT!!!! We first saw 20psi at 3100 rpms, that is stock turbo spool. But we got compressor surge or something and had to dial mivec way back so you could even get enough fuel in there. It sucks a bit because I can't utilize the extra compression fully but oh well, its a nice setup I think.

Mainly all that is left on the tune is to fight the boost control to where we want it. We were aiming for 28psi.

PS: THANK YOU GOLDEN! We didn't have the newest omni 4bar scalings for psi boost control but got it off your website. You da man.

Game ON soon

OH! One more thing, Schiedes you should do an overlay (PRETTY PLEASE), here is my 500whp track tune before, and this is a straight e70 non pushing it tune.
