When I first installed this turbo, I was running a split duration of HKS 280/264 and made just about the same numbers you see below. The motor could run in the mid 11 AFRs, 23 lbs of boost and was giddy as a girl. Since then, I thought the 264 exhaust was restricting my top-end power, so I unstalled HKS 272/272 cams with cam gears set at -2* respectively. The issue I don't like now is that I have to run her pig fat just to keep her quiet. Don't get me wrong...she hauls *****, but at a higher fuel consumption. At this point, I think I will swap out my cams for the 45th time. I've gotten quite good at it by now! Anyway, here's a look.

 

have you tried -3i -1e yet? may give you a little more knock suppression in the midrange. I tried -2 -1, -4 -1, and -3 -1. The latter gave teh best all around combination for me with hks 272's. I'm not on a green though. The greens I have tuned were very quiet once you got past peak torque. What kinda timing are you running?

 

Yes, you are right about the peak torque knock activity. Tip-in and AFR adjustment corrected this. As far as timing is concerned...not a lot, 6-11* through peak torque and power. She just wants fuel. Oh well, you gotta tune for what the motor wants. Once I get back on the 280/264 sauce I should pick up at least 10 more HP and torque. D'oh! I posted the SAE corrected graph...it should read 353HP and 342 torque uncorrected. This makes sense since I have to run richer and lower timing. I'll tell ya though...this turbo is a kick in the pants! I pulled onto a highway yesteday from a stop sign and she got sideways in a hurry!!!

 

How much boost and what type of gas are you using?

 

24 psi peak boost tapering to 20...this is on 93 octane. Hallman MBC

 

Why does that log show more than 15* at 4000 rpm?

 

Trust me, it ain't...at 4-5.5k, I'm only running 5-6*. It also shows that I'm running 42* at 2300 RPM...we also know that isn't right, right? Perhaps we've noted a deficiency in DLL.

 

Yummmmmie, I want that turbo setup.

 

Your timing scaling might be off then. My copy of DLL visualizes all my data correctly.

 

I would really like to see a power graph of a IX vs the FPGreen Turbos (before and after on the same car).

Come to think of it I would like to see a before and after graph of a 10.5 hotside VIII vs IX turbos.

 

nice numbers and pump 93 great.

 

My DLL shows the exact timing as that of the log. I have had zero problems with DLL. I do not know why yours is off.

 

i hate u 93 oct guys

 

I have been using 93 oct in CA since June of 06. Just find a gas station that sells 100 octane and mix to get the desired octane.

 

Thats not bad at all. In DLL I made 394 whp with tbe, intake, 280 cams, 24 psi 100 oct, dc manifold, ebay o2. Thats on 2005 evo.
