OFT Tune for OFH+Phantom ESC with 1.5 Dump Pack [Beta] - Page 4 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Shiv@Openflash · 07-05-2014, 07:40 PM

The highest boost pressure the factory MAP sensor is capable of reading is right around 5psi (depending on atmospheric pressure). So if you see your boost logs flatline somewhere around that, it could very well be higher.

Shiv do you know why some of us up here in Calgary(specifically with ofh) are bottoming out the AFR when on boost?

Wow @fenton you were right when saying the TQ250 spools faster and has really closed the gap on the TQ300. I compared your first TQ250 and TQ300 runs and the logs bear out how quickly the TQ250 gets up and on boost. Tried to get the pulls as "apples to apples" as I could from your logs starting both at 2692 RPM (TQ250) and 2691 RPM (TQ300).

Data is here (fascinating):

Does everyone who is running this tune have the OFH?

No. Some are on stock, modified, or aftermarket headers including but not limited to the OFH. Check out the Phantom ESC owners thread for an idea of ppls setups.

If you you are looking for a header to use with this kit, the JDL EL header is your best option. EL headers provide better top in power. UEL headers were great for NA cars as it provided better TQ in the DIP than EL. I would love to see the 1.5 dump 250 setup with a full Exhaust and no cats with a JDL EL header with E85 could produce.

Did you line then up when they both went full throttle though? Because I think the 300 did actually go wot until a little bit after.

This really is a non-scientific comparison of a section of the two logs you posted. IIRC the 300 log had several pulls in it. Which one are you referring to? I started the comparison where the engine RPM increased continuously with no dips from about 2600 RPM to beyond 6k RPM. However since they were your pulls and logs I'm sure you'll have the keenest insights.

Ya they both had multiple. The real take away is the 250 is actually a solid performer especially when it comes to spool and bottom end.

Will the TQ300 every be available for purchase?

The tq300 is still in beta testing but it doesn't make sense for BRZ or frs in its current form. The tq 250 spools up faster and has almost identical boost levels.

What testing have you done or seen to confirm this? I've seen the opposite.

I have no testing but based on dyno posted by several shops in an na application shows that EL headers like jdl and hks had better top in power. Not sure if the same logic can be applied to this scenario.

I may just be crazy, but I still want to see 2 phantom compressors hooked up in series on the car.
10 psi witin ~.5 seconds of WOT. We would have to limit boost to ~7psi for stock engine config. Have maybe 4psi over 6k, if the boost scales 1 to 1. This should keep us from needing new clutch,cooling,fuel mods. Fitment would be easy if you ran a CAI, or some slight piping work to use the stock airbox. The alt charger could just be another controller and could control the second compressor. Both could be hooked up to the same throttle switch for activation. All that would leave is the need for a dump 2.0. 1 dump pack for each compressor, or if It will fit; two 1.5's. I realize this is getting really expensive and outside the purpose for the phantom kit, but I can't help but think about the upgrade path of the ESC. I don't know if the OFT could tune for that type of setup, but think about it, double(theoretically) the boost acrost the range for an extra $1600. If you already have a 2.0dump and OFT.

ok bored rant over, commence crushing my dreams.
