a little bit after 5. I got there around 2pm.

 

you must have been happy after your tune. 53whp and 61wtq jump over baseline

 

Oh ok I left at 1:30 or so. thats too bad I missed it. Maybe I will see your car at a future meet somewhere.

 

your curve looks like an NA car. nice power all the way to redline.

 

a little lean from that cai...

 

who was it that ran 290hp/290tq with just a cbe, cai, and turbo inlet hose?

 

actually and NA car usualyl continues to pull/increase to redline, not flatten out like that. Looks like an NA car until the curves cross

Its strange how his torque curve takes a dive at 5250rpm. Usually the boost taper is more gradual, not a sudden dive like that

 

my torque took a dump like that too . I'll post it up as soon as i get off work.

 

it looks almost like a misread or something, do the other print out look the same? cuz the torque flatlines right up to the intersection, then it stedily declines, which I've never seen that linear of a decline in torque...looks wierd...

 

2nd pull was nearly indentical to this one. The 3rd pull has a little bumpiness before the 5200 point but was still of a very similar shape. I'll post them later.

HP and Torque are very close relationship to each other.
HP = Torque * RPM / 5252.
Basically, The current stock ECU + Turbo + Injectors is reaching a max torque. @ 5200 rpm or so, with no more power and nothing bad happening, the torque curve degrades as hp flatlines. Correct me if I am wrong, but I think is an ideal graph for a Turbo car of my setup. I'm pretty happy that I didn't see more HP gains after the torque peak because that would have been due to boost creep most likely. And my AFRs are stable so pulled timing or detonation was NOT happening.

So I think I've got a strong engine so far and I'll be feeling mighty confident when I get Mike & GST to tune it with better enginemanagement & turbo.

Edit: Here are the other 2 graphs.

 

You are kinda gettin in backwards. You are correct that HP is directly linked to torque in the ratio you posted

However, torque is the real thing that the dyno measures, then HP is calculated from that. For cars like the STi with smallish turbos, peak torque comes around peak boost, then as RPMs climb (so does heat), the turbo starts to go out of its efficiency range and boost starts to taper. As boost fades, so does torque. HP stays flat since RPMs are increasing

Thats why it looked stranged to me...it didnt really taper at all from 3500-5k the just takes a nose dive in such a linear fashion

I wonder if there are so calibration constants that were slightly off...

 

Stock 05 STi




For some reason I was running rich, any suggestion's to try and fix that short of getting a tune?

 

Jabels is how they normally look

As far as running rich, no, you dont want to "fix that" short of a proper tune

A local evo guy said yesterday "you can run rich for months, but you can only run lean once"

 

Thank's I showed the graph's to a few people at the meet and they said it was running rather rich for a stock STi.

 

If you compared Jabel's to mine in photoshop, our torque graphs taper at the same rate. So what's not normal about mine?
