True, That thing is like camouflaged in there!

Car goes on the dyno tomorrow sorry today, wow it is late!

Ran into some last minute issues with fueling, the 1050X were getting maxed out with the single 340lph fuel pump struggling to maintain fuel pressure. Fortunately, I had installed a secondary pump in the radium surge tank system to prep for e85 in the future.

I had made it easy on myself to enable the second pump at the flip of a switch, now the injector duty cycle is back to ~75-80%, and fuel pressure is looking good.

The 340lph fuel pump with 6AN fittings, according to AEM, is only good to around 500whp (depending on bsfc). Guess I'll be running two pumps from now on for pulls. May install a boost-controlled switch to enable the second pump only when in boost.

Anyway, dyno numbers within 12 hours!

And the results are in!

Keep in mind Eugene and I are still tuning the car a bit so there is still be some improvement to be had. I've been emphasizing safety in the tune over big power, so for 93 octane I'm happy with the initial results!

I did 4 pulls , each time taking one of the three prefilters off until we were running just the turbo guard. Unfortunately, I only data logged one of the runs. (Big whoops on my part) Was really hoping to show the boost impact of each prefilter.

Also really annoyed that the stand in for the tuner that normally does pulls kept lifting the throttle early.

The datalogs seem to show that the revs were brought out to ~7500 RPM but I never heard the rev limiter.

The belt also could have been set tighter. During the runs from the previous night, with no filter, I was hitting ~14-14.5psi

With the tighter belt, some additional tune tweaking, and a tuner that will actually rev out all the way, 550whp-575whp should be NBD.

Also want to say, the tune is set conservatively to the point where we aren't getting the slightest hint of knock during these runs. Big props to Eugen for working with me to ensure the tune is set with the safety of the motor in mind.

Turbo Guard Only: 523whp / 407wtq @ ~14.5psi (Speculated from previous logs)
+ 1 Prefilter: 497whp / 395wtq @ 13.0PSI (Datalogged)
+ 2 Prefilters: 467whp / 388wtq @ ~12psi? (Speculated)
+ 3 Prefilters: 458whp / 381wtq @ ~11psi (Speculated from previous logs)

I am around 12.5 psi range and I am running the turbo guard with 1 filter. I am also getting some slight belt slip past 6300. I narrowed it down to the JS serpentine side. The gates RPM belt seemed to fix the slip on the SC side I am only getting belt dust on the JS serpentine even with the extra idler pulley.

They make an RPM belt for the serp. K071065RPM. (if your on the ACE kit)

Try that and see what you end up with.

Not quite done, but here it is w/ candy blue pipes. Not so incognito!

How did you get the forward section of your engine cover to fit after the install? My forward section is sitting in a box on a shelf after my kit was installed, but I'd like to put it back on if possible.
