Haha, that's exactly what I was thinking. Of course it was even better when I was getting the discount on the P1 for being on the pre-order list.

 

I'm almost ready to order the whole setup (P2 Brain, Echale, Aperture) but was wondering if the #s shown are for a 91 octane map or a 93?

Ok guys... I just made a call to WORKS and found out the following information:

1. The graphs you see were done on 91 octane fuel
2. There is about 10-15 hp difference if you use 93 octane
3. The P2 comes with a new hose assembly/ T fitting, which holds the hoses between the waste gate actuator and boost control solenoid.
4. The hoses look identical to stock hoses so there won't be an issue when you bring the car in for service as the techs won't notice anything.

For those out there who only plan to do the P2 and nothing else to your car they said that by using 93 octane or higher can expect to put down about the same hp on the dyno (250hp) depending on weather conditions etc. So I can imagine that a EVO with P2, aperature, exhale and running 93 octane should be around 255hp+

 

Why are new hoses necessary? I thought boost could be controlled by the EcU alone?

 

Because the stock hose-assembly is physically limiting the boost to what the factory limits are, so we have to manufacture a new hose-assembly that enables the boost to peak and hold at 19psi.

 

did you notice that little restricor pill in there? If so pop it out it adds 2 psi

Is that not the same peak boost?
Can the WORKS hose handle more than 19psi?

 

I believe the new hose assembly contains a new brass restrictor pill engineered for the new P2 re-flash. Removing the pill does not provide a boost gain, it changes flow volume, and creates a different operating influence on the wastegate actuator/factory boost control solenoid. Typically just removing the pill results in higher boost, but only in the form of an initial spike. Remember that regardless of the size of the restrictor, the pressure level is the pressure level, it just take longer to equalize through a smaller pill.

I will let Works confirm this info, but my advice is use the hose and new restrictor provided by Works, and place your stocker in a safe place for re-install at a later date as required.

Is there a group buy or a dyno day planned for the P2 in the California or Los Angeles area?

 

I just want to see the gains w/o the exhale and aperture. Or are they needed to get near those gains?

 

yeah that'd be great if we can see the hp & tq figure for just the brain p2.

Wait!! I can do this for 50 cents (a new t-fitting and hose) If I play with it enough I can boost 19, 20, 21, 22, 23, 24, 25 psi - this is a poor mans MBC

 

We wanted to post the P2 details the moment we were ready to ship the product out, since everyone has been waiting. We want to have more dyno plots but we haven't had the time yet. Another small issue is all the cars we have for testing have the Aperture and Exhale, we've been too busy with our testing to revert the cars back to stock. Hopefully we will be able to post some plots without the Aperture and Exhale in the next few weeks.

Also just to confirm, these graphs are using 91 octane.

and Trev0006, there is a SF Bay Area dyno day at ATP in Fremont coming up on SATURDAY NOVEMBER 15 at 11am

Thanks

Cool go for it and your 50cents will turn into a $6000 dollar engine rebuild

 

Precisely why I have'nt done so I'm just trying to justify the "jump/leap" from 50 cents in parts when coupled with a re-flash make in excess of a $700 dollar upgrade
