Dorch S2 HPFP in route. Shooting to get everything installed in March with another dyno session in April to see what the Pure500 does on a dynojet in the US on flex fuel.

It would be awesome if you did a p500 run on the same 93 octane too

I’ll work to get that data point.

Looking to do a Mac effort 93 on stock (HPFP) vs the Pure500. I honestly don’t think there is going to be a huge difference. Maybe a power curve change by 200rpm and 20whp more pan

Please make me wrong though.

Very excited to see what it will do myself. Peak power isn’t the objective or motivation. I’m after a safe calibration for track. That really lead me to a HPFP and octane (via flex fueling) and if I’m doing all that, might as well do the P500 while I’m at it.

On an emix which is all I plan to run anyways, it will be plenty. Since the flex sensor is there though I’m happy to see what it does on 93 just to know. Though they wont be on the same calibration, same day, etc for a more controlled test of the P500. Still worth exploring though.

I was on my phone, it was surprising you could read what I said with all the typos.

Would you also happen to have your stock turbo dyno #’s as well for comparison to the pure?

Scheduled a session this coming Friday 3/1 to see what the stock turbo does but it won’t be with the Dorch S2.

The before and after will show BM3 S291 (running 93), Then add the P500/Dorch/Flex kit and go strap it down again after Bend Cal is done with it to get final 93oct and flex numbers on Ecutek.

4:00PM today. I’ll post up results tonight. Just a basic PB&J OG F87 on BM3 S291. CSF IC, Turner Charge Pipe, Active Auto DP… no DV or inlet yet.

Temps in mid 50s with 90% humidity. Post Pure500 in April will be hotter so that will be a factor when comparing results.

[CanadianM2]

Interested to see! My S291acn produced 381whp/421wtq so I would expect you to make around that or more using the regular 91 file and 93 fuel. But I’ve seen fbo m2 wildly vary due to dyno

I honestly can't imagine him making much more power, maybe more torque and a bit more midrange. 385whp STD or 375whp SAE. You have better breathing mods (diverter valve, inlet and intake) so that should make up a bit of the difference.

You're expecting 375-385whp on 93 with the stock n55 turbo? Isn't that e30 range for the stock turbo? I'm e-chassis pwg, so maybe my expectations are skewed low for what the slighlty larger ewg stock turbo can do?

You can find examples near 400whp pump gas.

It made 382whp 409wtq on a dyno jet. 58* Ambient air temp but pissing rain so high humidity. BM3 S291 running Shell 93.

Going to tune the Pure500 flex fuel setup on the dyno there once it’s installed instead of logging on the street over an extended period of time so I should have final results much sooner. Maybe even before April.

Manual or DSG? Also how do you like the CSF IC? Any noticeable lag?

Manual. CSF is a solid option for a plug-n-play choice. I’ve seen deltas under 10* over ambient at best. Normally see about 12* over ambient. It’s performed well on track too. There are better intercoolers (Wagner Evo3 or VRSF Race) but the CSF has done the job. I’ll upgrade to one of those other options in the future should the need arise but I’m hoping the CSF can do the job for 440whp.

Fbo ewg n55 M2 stage 2 commonly produce 370-430whp depending on fueling (91 up to e30)

I was watching my own videos from the track (I am my greatest fan!) and noticed on two separate videos/days, there was a 50 degree difference in IATs - 80 to 130 and 50 to 100. I don't think the CSF is very good for hard track driving (BM3 Stage 2 91). Stock intake. I am hoping my VRSF Race is much better this year.

I was pretty spot on. Add an inlet, diverted valve maybe a dry flow filter and you can do a little better than that.

Thanks for the data point. I super interested in the 500 results, are you planning to run pump at all?

E85 is convenient enough I’ll always run it, but with the flex setup I expect to have some good data on just Shell 93 before we increase the emix. Planning to dyno tune it on the same dyno so I’ll have the ability to overlay that before run with the pure500 on 93, and then finally the Pure500 on emix.

Here’s 3yrs ago from some of the older OTS maps and Stage 1 turbos. This particular Dynojet is a bit tough (reads 7-8whp less than others I’ve been on) and tunes have been dialed in a bit more since.

Also added a second dyno chart showing the TTE460 maxes out somewhere bn 480-490whp on E50.

Let’s see how the 500 does!

Pure 500 on pump fuel yes please!
