Default 07 STi SR56, Meth, G200, FMIC

I literally just got done tuning an 07 STi with an SR56. Now, I have tuned the 56 but this is the first time I've done it on an 07. The power is actually very respectable for the combo of parts. I'd like to see some more top end out of the turbo, maybe a bigger exhaust housing would do it, but for a stock shortblock, this should do fine.

Parts:
APS SR56
DR525
Invidia G200
Snow Meth
65mm APS CAI
DW 750's

Stock Boost control..

Very nice chris!

That turbo is a bit laggy for my tastes but the top end power is pretty nice. Just for comparison

Edit: I'm on crack. My dyno graph has different HP and TQ scales. Comparo invalid!

Very nice tune! Glad to see everything turned out well. I installed the FMIC on tuesday then bill told me to add the water injection kit to the list of mods but it had to be done by wednesday night! I accepted the challenge and it seems like it made some great numbers! Again very nice tune and great power at that amount of boost.

My FXT with a 16G made 245 hp at 3500rpm on your dyno where as that car makes 150hp at 3500rpm. By 5500 rpm I'm making 276hp but that car is making over 400.. HAHA.
Oh blah blah blah...

I totally agree with you, the turbo is super laggy, especially for the money you pay for it... I would MUCH rather see a GT52 or SZ55 on this car, but none the less, I do not get to pick what people put on their cars... If I did, the world would be a much more dangerous place.

Dave,

You did an excellent job on the install, very, VERY clean.. I took some pics of the car, I may post them up later.

Btw: I'm still a bit upset about the whole installs thing but that has nothing to do with you. Once I get all the parts put in I'll be coming to you. I'm glad you're posting up some nice graphs here to exhibit your work.

When reading the correct scales.. My car makes 200hp at 3500rpm. You can def feel 50hp. I think I would certainly miss the 50hp down there.

Looks ok, a little laggy and under performing pass 6,200 rpm. Well at least it looks better than a SR55. One day APS will get it right! (as far as turbos)

The car looks great!

Looks good Chris. Do you think the drop off up top could be attributed to a decreasing meth/fuel ratio and the resulting drop in octane as RPM's rise? I'm not sure how this specific system is set up but most basic meth/water injection systems suffer from this issue.

nice job Chris! Would an upgraded boost controller help hold boost to redline?

Oh and I forgot to get some new XX stickers before I left Monday, Doh!

Well, I agree in some ways. The SR55 has an excellent track record when it comes to reliability and consistancy. Now, the price you pay for these units should show some better results up top, especially with the lag.. Normally I would attribute the lag to the car, but every 56 I have tuned is just as laggy, no matter how much time I spend on wastegate duties.

Aside from that, power delivery on the street is very smooth and consistant per gear. I would absolutely love to see a larger A/R on the exhaust side to help with the drop at 6000, but this in turn would cause more lag.

I think the GT52 or SZ55 is much better turbo for the $.

Ed, no, I don't think so, and let me tell you why.

I tried a lot of things with this car to help with that top end drop. One thing I tried was to go aggressive on the curve after 6000rpms to see what the car would do, it did nothing, and I mean nothing. I messed around with AVCS to help with spool up, then I played around with TD and WD to help keep the turbo going.. Nothing.. I went leaner towards the top to help, nothing again. The turbo is stubborn to say the least, but it's features are much like the 55 with more lag. I want to say that the exhaust side of this turbo is killing the performance after 6000rpm.

Now, on the street, the car pulled hard to redline.. The drop off wasn't noticable at all, so that says something. Bill seemed to be happy, and will report back to me with some trap #'s soon to see how we did.

I love APS products, quality is second to none, but there are a ton of better options out there for less money IMHO.

Interesting... did you try adding some fuel to see if it would take any more timing up there? This may be the correct approach if octane is indeed decreasing up top.

I started from an 11:1 all the way to 12:1 with no difference at all. With the AFR at 11:1 she took in some great timing, but it made absolutely no difference in power, in fact, it peaked a little harder and wasn't as linear. This told me there was an airflow issue somewhere.

Makes sense. Sometimes there is just a restriction you can't do anything about.
