Default JB4 Map 6 and Dyno Results - 02-24-2019, 02:55 PM

Hi,

Attached is my log from 2 dyno runs, apologies for the large log, it was set to 10 seconds auto logging after 70% throttle, didnít realise it would catch this much data on the dyno.

Run 1 between 404-507.5 resulted in 445 bhp, wasnít the smoothest delivery curve.

Run 2 between 962.75-1057.5 resulted in 428 bhp, possibly because it didnít go to quite as high revs, however it was a smoother run.

Very impressed with the results, running a sports c-a-t and the ewg and ff harnessís. Also the car wasnít the first on so it was sat around for a little while after a fairly long drive to the dyno, so lower iatís may have pushed even more out of this !

Just wondering if anyone has any suggestions on how to improve this setup ?

Thanks in advance

Yeah I was really impressed !

Mods are an aFe magnum pro dry panel filter, custom c-a-tback exhaust, cobra sports c-a-t, and the JB4.

Only got a graph of the second run unfortunately, the AFR on the graph doesnít quite match up to the JB4 but itís not miles off.

Makes me excited to try out the BEFís once they are developed and released in order to push even more performance out of this amazing engine !

Nice numbers, what fuel are you using and what map 6 settings are you using.

WOW!! That's running 17psi flat?? Very impressive. I'm generally around 19-20psi with WMI. I've never hit the dyno, but I know the car is putting down some good numbers. This helps back up my butt-dyno. lol.

Again... really great info here and nice numbers. The car must haul ass.

I agree. 428-445whp from 17psi? Goodness. Your mods are nice but you hit this kinda hp with no meth? I need to get to a dyno. I’m at 18-19 psi routinely using WMI.

Thanks guys, yeah as I say I was very impressed by the results, can't wait to get a BEF alongside some meth, will get it back on the dyno once I get those too.

Think I may up the boost limiters in 1st and 2nd to help me with a bit quicker launching, although I'm yet to get any Dragy times, weathers not been good enough whenever I've gone out.

Edit: Fuel is just UK V-Power. I did have a bottle of boostane sat in the boot when I went to the dyno but decided I wanted real world figures (as I have actually ever used boostane in this yet)

What's the top PSI to run on the stock turbo without meth ? Thinking of upping it to see how the car performs, but don't want to cause any issues...

Wouldn't increase it hugely anyway, 17.5 psi flat and then up in .5 increments potentially.

Looks like your FOL is at 60 and you're maxing out trims at boost onset for a short period. Later trims look great. You may have to lower tip in a little (.5-1psi at 3000 and below), but it looks like you still have room . Just keep logging and posting for review. From 3500rpm and up 0.5psi should be fine... even 1 psi. There's probably not much room with FOL. Fuel limits will start kicking in some time soon. Just watch for timing drops. If they occur and trims still look good, it's likely that Octane is an issue.

Your also starting to get into a spot where IAT's are going to start asking for increased Octane or some additional cooling. Boost limits have many factors... IAT, Octane, Internal fuel limiters, turbo setup, etc. 20-21psi seems to be our turbo's efficiency limits, so your close to those already. You've also gotta leave room for adaptation due to weather and altitude changes. If you don't, you could run into issues. Just my .02
