No pic for me either.

Have you thought about a 3-port EBCS? Is the turbo IWG or EWG?

still can't see the picture. the td06 20g's always seem to spool late to me. They just make more power up top. The tune will impact the spool but if you're looking for 1000rpm better spool it isn't going to happen. Tuning has a smaller effect on the spool. I don't have any other kinugawa dyno plots to compare to but the first one I found of a blouch td06 had peak torque at 4300. Yours is slightly slower. Could be tuning, could be the turbo, could be both. Mike has tuned a lot of cars though I doubt it's much in the tune. Have you seen his time attack car?

it's a kinugawa turbo, all signs point to that.

Because you have a 20G w/8cm hostide. This is why I went with the HTA68 8cm hostside and I have an FMIC and i still have more lag then the previous VF52. As above nothing has improved my spool in the tune, the only thing that might work is MEth injection and higher timing but maybe that would increase spool 100-200 rom earlier. I am also using the PNP GS exhaust manifolds.

You are stuck where u are for spool, i would guess.

Question

see, I don't really mind the lag as long as i have power top end. But its ONLY 301hp! I was hoping to get over 350 close to 400 with the 20g...???

Anyone else with a 20g? have a dyno sheet that like to share???

I've seen other 20g that made over 350+hp easily... but I'm ONLY at 301!!!

Would another tune help? From some other tuner???

Who do you recommend in the bay area?

What does a stage 2 Sti make on that dyno? I've heard mikes dyno reads lower than most. 301 does seem low though. Did you ask mike about the tune? 20psi is pretty safe. If you want to push it more you could ask him to do so and see what he says. Do you have an egt gage? If not he may not feel comfortable pushing it harder. I know the forum is the first place you want to come ask other opinions but it would be good to talk to your tuner about it all. I talk to mike once in a while and he would much rather have your car safe than blow it up.

Something doesn't seem right. I have a Kinugawa TD05H 20g 8cm EWG on my LGT wagon and boost is great. I make 18PSI by 3400 which I thought was great for a turbo this size. I have not dynoed the car, but I am only running 18.5PSI of boost but with Virtual Dyno it is making decent power.

That is weird... Are your using the stock style turbo housing where theres a flange on the turbo outlet or do you have the sti style housing???

FMIC or TMIC?

I have the TD06 and yours is a TD05 , is that make a different???

LMK

thanks

You should search for Mike at GST and find out what baselines and similar set ups are putting out on his mustang dyno. NeedBB should feed his log into the virtual dyno on the Mustang setting instead of the Dynojet setting and see what he come up with. Makes a noticeable difference.

^^ definitely agree. Also yes the td05 and td06 makes a difference. The td06 will support more flow than a 20g compressor will flow and it lets the 20g make slightly more power up top but as you see, at the expense of spool. Does it spool the same on the street in 3rd gear?

I'm guessing yours was not dyno'd at gst so comparing numbers is difficult at best. Haven't you noticed the huge differences in power from different dyno's?

Don't focus on numbers. Does it feel faster? Is it running smooth? Those are the big deals. If you're really worried about numbers look at how much more you are making than a stock car on the same dyno.

FWIW I just blew up a TD05 20g running 22psi on a custom liquid intercooler setup, as well as Kelford 264 cams. I was supposedly only making 285awhp, but that was on a mustang that's been shown to read very low. If I went to a different dyno it could very well have been 350. The car felt like an absolute rocket.

Ya that's true mine was on a different dyno with a different tuner. The power I gained is a good amount. Pushing 18.5 psi. I still have the stock tmic so we couldn't push it anymore.

Talking

so now i need to re-tune on a different dyno? Does anyone know a good tuner in SF-Bay Area...

See, this is what I hate about letting someone else tune my car. I don't know what they did...??? I have COBB AP, wideband a/f & open road. Can't I do it myself??? Please help with info...(sorry for off topic) If there's a way, please show me, I can do it...


Thanks...

I would track down why you are spooling so late. You should be hitting around 18psi by 4K with that turbo. You can self tune google subaru tuning guide.

No, you just need to find out what the baseline of the gst dyno is. A quick check yielded 220 on a stock 08 sti, 210 on another, saw a rotated 30r at 335, an 18g in the 290's, etc, etc...

Haha, guess what I did last weekend...



td05 20g blew bad and it couldn't be rebuilt, I replaced the blown chra with a kinugawa chra and it spools really well on an ej255 with ej25d heads. AWIC too.

Nice awic man! And you're having good luck with the kinugawa? I've been trying to figure out what turbo to replace mine with.

Don't need another tune or tuner yet. Did you talk to mike about it? You can log your car with the accessport and see what it makes on an airboy dyno spreadsheet. That would be a good starting point also. Just start at 2000 rpm and floor it to redline. Then you can compare numbers from a road dyno.
