APS twin turbo - 640 whp at 9 PSI
Hi Guys, Just a quick update on the C5 twin turbo system. Our head tech just dyno tested the twin intercooled twin turbo system with high flow rear mufflers (APS developed rear mufflers which will be released in early 07) and after a little tweaking on the engine tune the stock ZO6 engine produced 640 rwhp and 622 rwtq at just 9 PSI boost on 93 octane fuel. Now I'm not entirely sure how durable the stock ZO6 engine will be at this power/boost level though it certainly shows that there's plenty of power potential in the little 346 cube engine.

The US Truck / SUV market will get some APS attention in 07 if all goes to plan.

Peter,
Is there any warranty on your turbo kits, specifically on the turbos?
Is there any stipulation on the warranty (i.e. has to be installed by an authorized dealer, etc.)?
Thanks

The DynoDynamics power output figures read lower than the DynoJet. I have heard upto 15% in some cases. That is impressive !
What size turbo charger does this kit utilize ? How many lb/hr ? I would have guessed a T3/T4 60mm ?

A BIG CONGRATS, those are HUGE NUMBERS on a stock C5 Z06 at 9 lbs of boost and the TORQUE IS WICKED!! A little 100% methanol/alky will help her live a longer life. GREAT looking Product and BEST OF LUCK!!!!!!!!!!

No doubt that methanol injection will offer a higher degree of engine safety. I'm sure that many twin turbo Corvette owners will go down that path especially because of the low 91 octane fuel that's sold in many towns across the US. Lucky that we all have the methanol injection option, without it we could all be power limited.
