Not being critical here, just trying to provide some info. I have the same turbos on my car and have lowered the CR to 10:1, yet I make 450+ RWHP at 9 psi. The GPI dyno reads right at 320-330 RWHP for a stock L99 SS, so it seems to be right on the button for expected HP. So even if yours is conservative, I don't think it is 110 RWHP conservative. Something seems to be wrong. The pictures look great so I don't doubt your workmanship, I would just look at the tune a little closer and see if you didn't miss something there. Hit up Rhino79 if you have any questions. He's been working closely with the guys at EFI to get my tune right.

But that could be because the IPS kit may have boost levels considerably higher than 9psi, so I really can't comment on that, and I'm not implying your kit SHOULD be making more power. Just wanted to point out the above. Have you toyed around with higher boost, or is that what you feel is a safe zone for the LFX?

Again, always great to see these kits and thanks for putting in the work!
With the Compression of these motors the way they are, 9-9.5 psi is the most we felt like pushing it too. If we added meth into the mix we would have no problem adding more boost. These turbos are good for way more than we will ever throw at these motors so we are good in that area.

This particular car was built for a 18 yr old high school kid kid by his father, so it was designed to be as conservative as possible. Once the tracks around here open up again we will be doing some track testing with the car to get an idea of where we are at.

I may even throw it up on the local dynojet to compare the numbers for you guys.

We have a Mustang dyno as well as the DynoJet so the best thing to do is always reference to a stock or base-line number. If a dyno reads high or low it will effect the stock number just as much as the final number.

We rarely do it on the DynoJet because its numbers are always the benchmark but just tossing it out there.

PS -- TuneTime, what does your fastest IRS SS run?

Nice car and kit! But I agree 9psi's from twin EFR's is massively low. I'm not knocking your car at all. Just pointing out that with that set up it should be making more than 90 extra hp with 9psi's as a base. Keep us posted on this awesome ride and lucky kid also. Subscribed!

I knew the American Racing/Farks car went 8.39 but didn't realize there was anybody else that was a tick faster than the 8.40 Darth Emma's car ran.

The American Racing/Farks Camaro IS our car...

Hence our name on the side of it.

I'm seeing a lot of comparison numbers but @ 3500 RPM? That's the low end of the power band, isn't it...seems like when I had mine on the dyno the numbers were gauged at closer to 6000 rpm.
