Oops. posted wrond dyno. That is is38 on e40. I have to find the kill mode dyno but I believe power matched the bigger turbos.

I still think the IS38 is a very good daily turbo. With the added reliability Dan builds into them, you can run the IS38 harder and have all that meat you see in the graph under 5,700rpm.

Update: My thoughts are if you ran the EQT on kill as well, the IS38 would likely only prevail under 3,500 (ish) rpm. Having said that, daily driving is mostly under 4k. I still think the L38X is a winner for someone who wants reliability and great daily driver performance.

That power band looks nasty. Is38s are no slouch when tuned right. Wish they were more reliable though.

The EQT tuned on E48 is only making 400HP - this doesn't make any sense

Dont know details other than boost supposedly being mild, like 27 psi on the eqt. The is38 was full e85 with send it tune.

This is a mustang dyno so add like 10% on a dynojet. Fyi i made close to 400 whp on a tomi on that same dyno and trapped 125.8 mph.

It's not named "Kill mode" for nothing

I would like to see more of Dan's is38x in the wild with aggressive tunes to see how they last before dubbing it reliable. There have been plenty of hybrid turbos, not referring to Dan's specifically, that have failed in the past. Also I take my car to the strip from time to time and launch at 5500 rpm so making more power on the later power band is preferable to me and spool isn't that bad. That was the point of me showing those dynos.

I thought the eqt was easily into the 400 range with a solid pump revision and maybe a little bit of e?

It is, Jon's dyno is just a mustang. It's probably making 430-440whp on e48 on a dynojet at 27 psi peak with mildish timing. (according to Jon)

Apples to Oranges. You are talking drag racing, I am talking daily driving.

As for reliability they are already out there in larger configurations with the same precautions for reliability built in.

Yep! The L450 makes 400whp at 25 psi on a heart breaker dyno dynamics for example.

Getting 400whp out of the EQT or L450 on bone stock (US Market) factory fuel should not be an issue but close to the edge. Anything more and it's going to start looking for fuel IMO.

Disclosure: Dyno numbers vary greatly, proof of performance is at the track.
