How can I bench test a COMPLETE L98 engine..TPI and all - just restored

corvette95 · 11-21-2009, 10:16 AM

Just finished a complete NCRS rebuild/restore of my 89 L98 engine. Its OE / refinished/ complete with all factory emissions and TPI injections but I want to bench test it before I install it. Thinking the obvious, computer, harness, cats with o2's. What about emissions ,egr operation etc. I want to make sure its perfect before the install. Is there a prefab set up anyone makes to make this a simplier project than me rigging all this up? (not talking about engine test stand, mainly the rest)

It would be a PITA to bench test a EFI motor.

I'm in the process now of having the TPI motor in my '88 rebuilt and it will go into the car before being run. I have confidence that the accessories will be fine, well save for the AIR pump and maybe injectors.

Do you have a reason to suspect any of the accessories?
If the motor is a mostly stock build, emissions should be fine.
