Blue line is stock STI on their dyno.

Car pulls hella strong.
Next on the list is a big maf tube, boost controller & some tuning around ~25psi! Excellant work by AMR. :devil:

isnt that super low for meth? Do you have a afr plot to go with it?

Well, if that blue graph is the base line power then this dyno is reading about 50 whp/wtq lower than an average dyno.

The blue line is stock STI.

I wanted a conservative tune for now (daily driver), and I think meth can be a great safet net. Im going to let AMR tune for ~25psi, with some more agressive timing, after the boost controller gets here along with big maf tube.

:devil:

GREAT NUMBERS! Car must pull like an animal. When is full boost?

i think you're right

i think you're right

someday people will not just look at peak #'s and realize each dyno is different.

compare it to the stock blue baseline, the sz55 + meth made an additional 150 whp over stock.

thats considerable.

With that overlay of the stock STi, it looks like you didn't lose power anywhere in the entire RPM range. Very nice... Crank that bitch up to 25psi and repost. Is that IWG or EWG?

Very nice gains over stock for only 19psi. I am curious as well, IWG or EWG?

19psi with meth? Whats wrong with this picture.. Most guys can make this same power with just pumpgas and 20-22psi.. with 0 issues.. If you scroll down a few threads you can see that a green with just pumpgas makes more power on just pumpgas and a TMIC to boot..

And with what we have learned in other threads those dynos, they can be manipulated very easily.. So unless its an actually comparison of the same car before and after with all the same run conditions posted you wont really know the thruth.

The butt-dyno can tell for sure. Or you suggesting that a butt-dyno can be screwed with as well? ;) :D

LOL.. As long as your happy with it that is all that matters!!

the car you speak of was measured on a different dyno, so you really cant compare the power measurements

and just because such dynos can be manipulated doesnt mean that his was

in my extremely humble opinion, i feel that his numbers are right on (and impressive), especially if a stock sti does ~200 on the same dyno. stock tunes seem to be pretty consistant on the same dyno iirc

uhh the car you speak of was measured on a dynojet, so you really cant compare the "power" measurements

The car I speak of was on a dynojet.. and it made 30 more hp on just pumpgas on the dynojet. So lets say that on the dynojet a stock sti makes 235-240.. Thats still about 150 more whp.. On this is still only done on pumpgas with a top mount etc.... Does that make sense?

Im not sure what your getting at, or trying to prove:confused: .

So your scenario is running *more* boost and making similiar power, with no issues. I went with meth because I wanted the added safety (for now). :rolleyes:

You can only run so much boost on the stock sized MAF housing before you max out the voltatge. He needs a big MAF and a re-tune to realize the full potential of his setup. Great nubers BTW!

^and hes no where near that number and i think jr knows a lil about tuning. Theres no reason to be running meth with only 19psi.

OP: Did you get a afr plot?

^^ well you could advance the crap out of the timing and have a much more aggressive tune while still only running 19psi.

Since that dyo reads low from the jump, those seem to be good #'s.

I didnt get a hold of a afr plot yet. meth was installed knowing that a big maf and boost controller are en route soon.

My point exactly... Why is that needed?.. Why run such extreme timing when that will be the first thing to break the stock pistons when it knocks. Why will it knock? one day he will be low on meth, or he will get bad gas and that AGGRESSIVE timing will kill the motor. A conservative Pumpgas map with 2 more PSI will make the same power and still be super safe.. TIMING will kill ****.. boost wont.. unless you run alot of timing along with it..

MAF?? Na... not the problem.

Swift.. it doesnt read low...

19psi + Meth.. FTL

That car should make over 400hp safely with meth... and I don't care what dyno your on.

GST and Buschler come to mind.

But 19si is way to low..more like 22-24psi.

wow, he said hes going back for another tune when he gets some parts in.

congrats, must feel great.

This car is a beast! The SZ55 is an excellent bolt on turbocharger for the STi. We cant wait to step this thing up. Give us a call when you are ready :banana:

boost itself is only have the picture to making out MAFvoltage.

MAF voltage peaking out on a stock sized MAF can be also atributed to air flow.

For example lets say a STI MAF tops out at 400WHP.

If a
Stock STI Turbo 340 WHP at 24 PSI
Green makes 400 WHP at 24 PSI
FP Red makes 400 WHP at 19 PSI

The real underline factor to maxing out a MAF is Turbo CFM flow. A larger turbo will max out a MAF at lower boost than a smaller one.

Not trying to show anyone up just stating the other part of the story.

Unfortunately, that will never happen:(

It's also unfortunate that car owner X with X hp will make claims that his car can beat car Y based purely on Y's claimed hp, rather going to the track to discover the truth.

It's just pitiful when car owner X got X hp form one dyno then later goes to another dyno...same tune and gets a graph with less hp and delayed torque and starts complaining. IT'S JUST A FRIGGEN PIECE OF PAPER!!

You really want to kow how much power you gained or lost, or you want to compare car to car, go to the dragstrip and analize the slips.

Good numbers. If it feels good, congrats. I think we all wanna see the AFR plot though.

Right! I totally agree with you. 19psi from a vf39 is not comparable to 19psi from a FP Red or 35R. That is what i was getting at but i guess it came out wrong. I maxed my Big MAF when getting my race gas map done on my FP Red.:devil: Time for Hydra.
