ScionSpeed scion 426FWHP. Stock engine block.

In our quest to find the mechanical limits of the 2AZFE motor, dyno tuning on the Scion Speed project tC continued on April 2, 2005. Our project tC test vehicle has now been upgraded to Stage 3 specs.
The upgrades include larger 3" downpipe, larger GT3540R ballbearing turbocharger, larger RC engineering injectors and new map.
At the end of the session we managed to squeeze a simply amazing best of 426.15 WHP and 374.64 FT/LB of torque @ approx. 17-18psi of boost pressure on 103 octane VP unleaded fuel. This equates to approximately 491HP and 428 ft/lb @ the flywheel.
UTILIZING ONLY BOLT ON COMPONENTS, we have effectively tripled the standard output. THIS IS STILL ON THE COMPLETELY STOCK ENGINE!!! We are dumbfounded at the strength and flow characteristics of this engine!
We are now at the limits of the 255lph fuel pump. As seen after 5000 rpm on our dyno sheets, the Air Fuel ratio started to lean out due to falling fuel pressure.
In an attempt to break our previous 12.5sec ј mile record, we attended the NHRA Import racing event in Palm Beach Florida on April 3, 2005. Due to the new found HP and very high grip of the track, our passenger side axle sheared in half during qualifing rounds, ending our day at the track. We have sourced a new axle and will make another attempt in the next coming weeks. STAY TUNED!

yea thats awesome power... what is the longjevity on these turbos though I want to keep my car for atleast 8 years and was figuring eventually going with a stage 1 turbo or a s/c... what would you think the tc would handle for a long life.

is this the first dyno?
Put 1200 miles on it. Post a compression check and dyno.
First blows are always fascinating but even more so are the long term reposrts.
Good work so far, can't wait to see what the reults are later.
