Cool Project White Dragon Lives! 450zTT 850+ RWHP on 93oct "Dyno Broke"

Many of you have heard of the Mythical Build, but not many have seen it in person. The car has been in and out of shops for the last several years. In early February I got the car back on a truck in a running condition. Granted it still had a lot to sort out including an exhaust leak. Long story short, with the help of a friend (Kyle Klessig of Z1) I was able to pull the kit down inspect and inspect everything without dropping the motor...



I can definitively say "One can definitely install the GTM kit with the engine in and on jack stands... Not I deal but doable..."

What we found was the typical turbo manifold exhaust leak that most have seen... Luckily I have a friend who was able to get me a spare set over night "Granted used but in excellent condition!".

With the kit pulled down and the new manifold in a few days later we had scheduled a second day to put the car back together... But before we proceeded I took a look at the turbo and the manifold and because the manifolds are tradition T25 and I am running the T25+ (performance similar to a T3) housed custom GT3582R turbo I noticed some restrictions in my turbo manifolds... So, with a skilled hand I grabbed my dremel and a grinding bit and put in a few hours of shaping and material removal to induce better flow.

Pic for comparison:


This mod should increase peak horsepower and allow for a slightly better spooling turbo.

So after getting the car put back together on one sunday afternoon I scheduled time to drive the car down to Z1 for some special treatment from Kyle and Jon! We noticed the Bank1 was constantly running lean even after reinstalling everything and the car had a hard time idling... well after further inspection at Z1 and with the Boost leak tester we found out that one of the ID2000 injector's o-rings was torn and allowing air into the cylinder. Pulling the custom fuel rail was a PITA! and we had to grind down a corner of the rear VVEL bracket if I remember correctly to allow the injector to sit in correctly and not bind. Once the injector was in it was back to wrapping up the car and prepping for the dyno!

So let me take a pause here...

Several years ago Jon Parham and I had a brief conversation that ended in a (prophetic) promise... that promise:

"Jon, upon the cars return to Atlanta I will break your dyno hahaha! That is a promise!"


Fast Forward back to last Saturday night:

The car is idling like a stock 370z despite having been milled to a full 4.5L monster! We pulled the car up on the dyno (on an OsGiken Triple plate Race clutch) *note: we were taking bets on who would stall it out the most... not a sit in traffic clutch HAHAHA!*

We strapped the car down on the dyno, hooked up the wide band and prepped for our first couple of runs...

Once the car was ready Jon wanted to run the car a few times to get the car up to temp and to get a feel for what it was doing and what was going on to the current tune. Sadly I did not get video of these runs but was able to capture our last run! Jon did not even get a full session in before the Dyno broke!!! Here is a video of our last run before shutting everything down:



The car hit 700rwhp on 93 oct by 6300rpm and was continuing to climb past 800rwhp when the dyno crapped out due to a speed sensor. This is without Jon making any changes to the tune which is not complete. Once the dyno is up and back in order we will do more videos for everyone.

Old Dyno:
