If that is the MAX gain in torque and HP, the DASC is not a great deal. What were the stock values?
This is the DASC Kit is stock form.
Max HP: 160
Max TQ: 141

I will post the chart tonight.
Max HP: 120?
Max TQ: 130?

I think Chad's numbers might be off a bit. It looks like Chad's dyno runs were done for tuning purposes, not for max power output. I believe dyno's are setup differently when going for max hp readings, that's what I was told. Chad's dyno chart does a great job of illustrated the hp and torque curve that you can expect from a DASC. Very torquey low end then a small dip in power with a jittery increase in power. (I believe www.techniquetuning.com has smoothed out the curve a bit).
Chad, were your runs done at WOT, or at partial throttle? Are you using your intercooler?

Even if those numbers are correct, it's still a ~35% increase in power all the time.

I admit, I'm no expert on assessing dyno charts, but those increases in torque aren't large.
Maybe I'm not getting it. What I want is increased torque off the line. I don't care about top end or how much power I get at 4500rpm. For me, the thrill is from 0-60 issues. Wouldn't a lightweight flywheel and higher ratio LSD give me more increase in torque and initial acceleration?

So you spent 3grand for 40more hp.
I thought it was 200-210hp with the DASC added onto a stock ti.

My g-tech shows 211hp (@ 14 degree fahrenheit :biggrin:) and
14.43@101 mph with the automatic transmission. I haven't run with the 5 speed yet, but it should quite a bit faster.
I am happy with the results, I think I got over $3k worth of pleasure from it. The only guy in town with a dyno charges $250 for a run, so you won't be seeing my dyno chart! Does anyone else have a dyno chart with a DASC?

the DASC doesnt add a lot of power, but more importantly it spreads it out all over the powerband. so you pretty much have full power from 2k to redline. Plus once you go boosted adding more power is a piece of cake.

Wow... I leave for a second an hell breaks lose.
OK, here the answers to some questions.
My runs were made in third gear pulls at WOT with the ambient temperture at about 88 Degrees. So the temps could have resulted in lower numbers. The car that was runs was my TI that has a DASC kit in completely stock form RRFPR and all. You can compare my run to one that Nick G has on his site to see a good comparison.

My numbers were a little less then his were. I am still unsure of the exact stock numbers and I will post the chart tonight. I was just guessing hence the (???).
With the DASC the first time you take the car out you will feel the increased low end torque before you even put your foot in it. Just driving around town the car picks up and goes a hell of a lot faster.
If you change the diff you will get S/C like performance especially from a (4.44), you just will not be able to go fast then 90 MPH which in the end could slow down you 1/4 miles time. With the DASC you get the same type of acceleration and can go still take it to the limiter.
I spent 3K for 40 RWHP The thing is that it is power to the wheels. Now you have to think about it that it does put you in the negihborhood of 200 HP at the crank if you don't have a drivetrain loss.
A stock DASC will never have 200 RWHP, I don't care what anyone says. The DA site has a correct chart of HP measured at the crank I believe.
I assure you that the kit is worth the $$$
Hope that helps.

Correct me if i'm wrong.
now if you have a dyno done it shows rwhp correct? Not the actually hp but RWHP.

The graph i posted was from a 1.9l z3 i would imagine it's around the same hp as a ti. Give or take a few. it's showing about 200-210 rwhp. I've seen a graph on a ti awhile ago showing 190rwhp on a ti from the downing atlanta. Now was the graph exaggerated?

Tyler,
The graph for the DA site is not RWHP to my knowledge. I know a few people that have a DASC as well that wish they got 200 RWHP.
The only person that I ever heard claim 190 from a stock kit is Chris from Understeer.com. I have never seen the chart so I personally think he is just blowing smoke.
If you can find the 190 chart I would love to see it.

Well i'll do some searching tonight to see if i can find that. It was inbetween 1-2yrs ago that i saw it.

I'm diggin' those numbers. The torque goes way up between 2000-4500rpm. If our cars will give us those increases, then I'm buying.

If you want more info on what engine that was check out the website,there is an article on what engine it was. I swear it was a 1.9l z3

A stock chart has been posted. It is not mine but I knew I was off a little on the numbers, I was right with the HP, but TQ on a TI is like 104

hey I call those #'s dont count cause it was like a 100 degrees during the dyno run. :biggrin:

what's with the fairly big drop around 4500-4600 RPMs (99ti w/DASC)?

If you look along the AFR curve that is the point in which the car begins to go lean.
