LTX-12 20B Dyno numbers

Finally had a chance to get back to a dyno after the turbo and boost controller upgrade. With some help from a good friend. Lee, from Toscano Racing, we cleaned up the super fat AFR on the top end. Can you say almost 400 RWHP @ 7psi!? After that we, tuned for 12psi and ended up with:

525 RWHP @12psi and 411 ft/lbs torque on 93 octane pump gas! Talk about sounding sweet.

After I left, the guys from the shop called and said that I could come back and pull again for free because the dyno was set @ 4500' elevation instead of 900' so they were so excited to see the 525 at that setting, they said it will be even more with the elevation corrected.

Nice numbers Derrick! Glad to hear that your car is making some good numbers.
I do have a question about the elevation though. If the settings were set to a higher elevation, shouldn't the numbers be higher than when it was set to lower elevation? I would imagine that it should with the correction factor to make it more comparable for different altitude. Maybe I'm not thinking this right and you can enlighten me on this if I was wrong. What was your correction factor? I would imagine that it should be somewhere around 1.05?

4-5 psi @ 2800rpm and full boost by 3500 or so. Around 4K rpm the car is pulling so hard it it feels like you were just shot out of a sling shot!

I am not a dyno expert so I can't answer that question. Need to ask the guys at the shop. I was just quoting what they told me. All I know is it runs and sings as no other engine around!

Great tuning Lee (tearbo2).

Derrick I wonder if that 525rwhp fells anything like my 750rwhp Supra (sold) I know what it feels like to be shot out of sling-shot!!!!
Are you going to take her to the track? You can borrow my tires.

Hey Bill, when will the red one be back on the street? Did Lee install the "Bubbles under boost option" to the exhaust system?
