Please Look TDO6H 20G Dyno Run

[midnght]

I did a baseline run with my NEW setup.

MAX HP=286 at 6400 rpms
MAX TQ=28 at 5200 rpms

It looks and feels like it starts its pull at about 3900 rpms and stays pretty strong. I only tuned it with and S-AFC II and an EGT peakhold.

I hit 19psi and held it from 18.5psi-19.5psi all the way through. I was running 93 octane. I know there is more there, I am just looking for opinions on how I should adjust to get max hp/tq from my new 20g. For now I have the stock clutch, but an ACT 2600 should be in by nest week.

I did my own install and it sounds and looks like it is running great. I was looking for more power, but I am satisfied with the run. It smells rich still and I have the % going pretty low.

My throttle points are set at:

LOW-27%
HIGH-80%

And trims are -24% all the way through LOW Throttle and -34% all the way through high throttle. With the exception of the 4600rpm and 5000rpm are set at -36%. I also richend the 7000rpm and 7600rpm with the thought of it needed more fuel because it is being reved so high. The reason I dropped it lower there was because during my 3rd gear pull on the highway it bogged down at that range so I leaned it out more. That was my settings on this baseline pull.

The scribble on the sheet is my talking and asking questions to the dyno guy. Feel free to correct me if need be. ( I am no expert tuner so this is what I did from reading and talking to different people.)

Any help and CONSTRUCTIVE critisizm is appreciated!

The only thing I am not looking for is people saying they can make more power than me with a smaller turbo. Help me, don't bash my setup cause it is INFERIOR to yours.

Thanks Again!

That 93 octane is killing your dyno results

 

[midnght]

What would you suggest with some c16, psi wise?

 

[awild]

Put in at least 100 octane if not 110. Then up the boost. You have a 20g for God's sake and only running it at 19psi? Crap I can do that on my stock 14b with my supporting mods. Search around and see what others dyno with a 20g. Sorry I cant help a ton but if you have all the support for a 20g and the turbo to follow, you should be well up there in HP.

 

[midnght]

Yeah, I was looking for more. I am still on the stock clutch that is slipping already. I also do not have a pocketlogger to see anything besides egt temps. I know it is not the best thing to tune by and I don't want it to get to rich or lean. I figure I am running pretty well for an amatuer. And I still have about 100C to play with. So i no I got room for improvement.


Just taking it one step at a time. I got everything to flow this except a better clutch to handle the power. I keep it low on the 93 octane. I will turn it up when I have better fuel and tunning done. I need more time on the dyno. The reasin behind the 93 octane is because this is my daily driver and that is what I will run in it all the time. There is only one place around here to get 115 oct at about $3.50/gal.

looks like your running pretty rich, turn up the boost to 22psi and lean it out some get the a/f to about 12-13. what are your egt temps at?

Before you do anything else you really need to get at leaast a pocketlogger. I know you don't want to hear it but I wouldn't be cranking the boost up any more on a 20g with a stock sidemount until I could see how bad my timing is getting yanked. You should also look at getting an AFPR.

He doesnt have a stock sidemount according to his profile:

SBR 2G20G (tdo6h), EVO III Ported Exh. Manifold, MSD 8.5 wires, 660's and 255lph, Black S-AFC II, Greddy EGT *Peak Hold, Autometer Boost Gauge, Greddy ICP Kit, Big Greddy FMIC, Greddy TypeS BOV, VRS 3" o2 Elim. turboback SBR MBC, Apexi TT, FIPK

Looks pretty rich. Did they have a wideband O2 there? A logger would be very helpful as well.

My bad, I missed the FMIC. Nevertheless 20g or bigger with no logger just doesn't make sense to me.

True that, I'm getting one once I get a Safc

My temps never passed 825c. What am I looking for, AF ratio wise? I was told each car is different, and I should shot for about 12.5:1. Does this sound correct?

Yeah, I guess I should have listed my mods in my post. I am going to purchase a pocketlogger, I just don't know what Palm is what yet. I would like to see different colors for graphs. I am looking into it as we talk about this.

I was also told to not worry about the AFPR for now since I got a Low Pressure 255. It might be working my stock regulator more than it should, but not enough to harm anything.

Dont do it!

Get DSMlink

 

[midnght]

I just wanted something to get me by till I get the clutch installed and find an E-PROM to mate with the DSMLink.

It is pretty cool that the developer lives down the street from me. Tom is a real nice guy. They are working on a new version so the pocketlogger will do for now. Then I will sell the pocketlogger nd use the money for something more useful.

Even on 93 octane, you should be able to make over 300 whp, probably more like 325-375. You need to tune it more, and turn up the boost.

On race gas, preferably something with an octane rating higher than 110, you should be able to run 26 psi, and make close to 400 whp (or more).

With my 14b, I make about.....oh, sorry.

I wouldn't run 26 psi on stock head bolts if it was me personally. As for 12.5:1 A/F ratio, I think you want around 12.9 on race gas. Personally, I like to tune to around 11.4-.5:1 on pumpgas just to be conservative.

 

[DCJ98GST]

I am really interested in how this turbo will do once you get it tuned. Most people match the 20G with either the TD05H or the TD06 not the TD06H.

The TD06H should flow 13% more than the TD06, and 44% more than an unclipped TD05H!!

So 18 to 19 psi may be flowing the same amount of air as the other turbines at 20 to 21 psi.

With a good set of cams it may be a beast at 20 psi.

 

[midnght]

Looking to get the clutch in, then I will go with some 94 octane. I just so happens that the station next to my one I get the gas sell it for .02 cents more a gallon.

$125 gets 1 hour and S-AFC tuning from a very reputiable guy. (MSP racing has an 8.34 sec street supra, they know there shit!)

He told me about 1 hour to get some good tuning done. This is also with wideband o2 help.

 

[midnght]

Yeah, that af ratio was for pump gas, I would def. go a little leaner for the 115 octane. I believe you can save 2 different settings on the AFC 2. I have to look at it again.

 

[azteck2]

I just dyno'd my car last weekend, my set-up is similar to yours and i put down 302hp at the wheels on 110 leaded gas. On the last pull they hooked up a wide band O2 and I was around 10.5:1 from 4500rpm and up...super rich! The funny thing is on the pocketlogger everything looked fine (as in not rich) just goes to show you really need a wide band to tune. PS my run was at 20psi with full boost by 4200rpm.

 

[midnght]

Yeah, that 286/281 was at 19psi on 93octane with an average of 11.2:1 af. I want to go get some 115octane and turn it to about 25psi and log ONE run with that. I just have a little more tuning to do with the car.

They charge $125 for 1 hour of afc tuning on the dyno. I might take advantage of that in the near future. I should also add that my clutch is horribly worn now. Maybe after the ACT 2600 goes in. I am glad to see that I just need some tuning and that I am not that far away from the 300hp mark I was originally shooting for. I bought the 20g for this simple reason. I don't have to run super lean on pump gas to get my 300 whp mark in my GST stock 7bolt. I wanted to reach this at 20psi, i will keep trying.

A pocketlogger cannot really tell you how rich you are.

However, do not concentrate too much on A/F ratio. As long as it is in the ballpark, you are fine. You need to concentrate on timing advance, knock, and boost.

I personally would run 25 or 26 psi on stock head bolts. Worst case scenario, you have to do a HG and get ARP's, and then you can run even more boost.

TDO6H is worlds better than the TDO5.

Yeah, I need to replace the HG and get some ARP's in there. First, clutch then I want to replace those to be able to get more out of this. These were my S-AFC settings during the run:

Low Throttle
-21%

High Throttle
1000 -26%
1600 -26%
2200 -27%
2800 -31%
3400 -31%
4000 -34%
4600 -34%
5200 -31% throught the rest of the rpm band

------------------------------------------------------------------------------------
AFTER THE DYNO

My adjustments went as following but I was unable to do another pull, as they were closing. I saved the settings and have them as follows.

Low throttle
-24% across the board

High throttle
1000 -26%
1600 -26%
2200 -27%
2800 -33%
3400 -36%
4000 -38%
4600 -38%
5200 -35%
5800 -34%
6400 -34%
7000 -33%
7600 -32%

It seems to be pulling like a raped ape now.
Now, with the new settings, it sits at 875c. It feels stronger and I break lose in 3rd gear easily now on my stock suspension setup.
I need to do a log and see what type of timing I am getting. It doesn't smoke or backfire. It doesn't run extremely hot or have low/high oil pressure. No hotter than a turbo can make it anyway.


The hard part in getting knock recorded on the 2g is you need a DSMLink. But I want to use the pocketlogger as a way of seeing my timing being pulled. One other thing is it sounds like I am leaking boost if at 19psi if I don't have it floored. I am sure of this because I will accelerate slowly and then once I hear the leak I will go to 100% throttle and then it goes away. I was told it was because I do not have the bottom nipple plugged in anywhere. If anyone has some advice as to where I can "T" into before the TB, I would greatly appreciate it.

Thanks for all of the reply's.
