Default My COBB daydream...dyno'd @ Tuning Technologies

Yes, that right....in the midst of all this COBB talk, I dyno my COBB stage 2 WRX @ Tuning Technologies in So. Cal earlier today. Mods are Helix uppipe, Helix cat "less" downpipe, Borla XR-1 catback running COBB's California 91 octane map. This is a DynoJet dyno....and to say the least, Im very dissappointed. It pulls great on the street, but the dyno numbers dont show that....oh well. Below are my Stage 1 & 2 graphs. I took out the stage 1 graph...couldnt get it to resize. My Stage 1 put down 191whp 194trq @ Harman Motive with CF:SAE Smoothing 5...it only hit 13psi on the dyno, so maybe thats why the numbers were low...




***ALSO, I am the "only" WRX to dyno @ Tuning Technologies, so they dont know what stock ones put down. So, if you have a stock WRX, go there to dyno :-). They have dyno'd one other STI and it put down ~255whp ~270 some trq....but I dont know what all his mods were.***

Not sure why you are dissappointed. Cobb claims 224.4 peak hp and 223.2 tq, most likely on something better then cali 91 oct.

You got 214.5 peak hp and 222.24 tq.

I'd say that it's right on par with what it should be.

Wow it did better than mine. I will see if I can dig up my dyno run at Harman. I think I only put out 204 whp on the regular Cobb stg 2 91oct. I did notice an increase in power running the 93 octane map with 93 octane gas of course.

this dyno reads higher than Cobb's dyno, and it's reading low. i'd be dissappointed too.

id be curious to see how changing that AFR curve would affect things...ive just never seen one that looked like that, really. but if the power is where it should be, then you should be fine.

Just curious, did you do any baseline pulls prior to going with your Stage 1 pulls? To look at you Stage 1 and Stage 2 pulls, they seem to be right on ... They may be down about 6hp for Stage 1, and 10hp for Stage 2, but they do state that's with 93 octane ... You'll be at least 5hp off just due to that ... I guess all I'm saying is your numbers look good, but if you never ran a baseline, you have no idea where you started ... You very well could have been low on that dyno to start ... That doesn't mean you're not making the power, it just means all dyno's read different ... Some of them vary wildly from one to another ... If you don't know where you started prior to modding, then you have no idea how much power you made with the mods ... Just my .02 ... All in all, it does look as claimed though ...

I really don't understand all the hostility towards Cobb's AP ... I mean really, 90% or better of the poeple out there get exactly what they're looking for ... Sure you may not see all the power your capable of squeezing out of our engines, but your talking about 100% off the shelf stuff ... It's plug and play, and it's conservative as we all know ... You want to squeeze some more ponies out, then you buy a UTEC or ECUtec, and pay for the tune that way ... There's really nothing to question, is there? I also still think after re-looking at everything, that your numbers are right where they should be ...

Without a baseline for the same car stock, this means nothing....

Attention n00bs

A dyno is a tuning tool, NOT a comparative measuring device which proves/disproves that car B on day B on dyno B at temperature B at altitude B with relative humidity B operated by operator B using inputs B with be the same/better than your car A.

All in all, I am pleased with COBBs reflash. It feels really good on the street. I think the lack of "proper" airflow through the top mount also limits the numbers...and then you have the "de-tuned" Cali map on 91 oct (76 brand atleast). I want to go back on the 91 octane map with atleast a blend of 93 oct....when $ permits.

Shiv might be coming to So. Cal in late Feb and I want to see the difference between this reflash and his "base" reflash.

Looks fine to me aside from the 10:1 AFR from 5200 onward. Dunno what you're disappointed about.

I wish more people would listen to us.

I prefer to say that a dyno isn't a way to measure your e-penis.

ok besides the fact there is no stock comparison, this is on craptastic gas and all.

I noticed your noted PSI level...where did you get it? if from the AP, it is low. why? well as I recently learned more about the effect of heatsoak on your TMIC and what it does to your max boost....and the fact you comment of lack of proper flow.

You should be closer to 16 psi max boost, and if you add a few more psi, this should add a pretty good hp boost.

Note I am NOT a dyno guy, NOT an expert at all on TMICs, I am just using deductive reasoning based on a few things you noted and I have experienced myself.

comments?

PSI was measured from my Omori boost gauge...peak was ~16 psi tapering to ~12 psi. Im going back today so I will try and get stock EVO dyno numbers. All in all, I think the numbers are OK....because of the Cali map tune and piss gas the hp is low...the torque is still there...an increase of 45-50 from an estimated base of 175-180 torque, and on 91 I think that is acceptable.
