Engine/Transmission (1994 - 1998) dyno with plate out?

[JAmos]

Trying to get my front end together for a dyno run this coming sat. I would like to take my #6 out and run with no plate on the dyno and up the street and make a little more smoke. My questions are will a stock clutch hold 2 or 3 dyno runs and a little driving, and how long can I let the dyno opperator run the truck with high egts? Can a full run be achieved without melting down? I am mostly stock, straight 4-inch, #6 plate full forward, timing around 15 deg. , wastegate blocked(36 psi max), 4k gsk-stock valve springs , k&n, and of course heavy right foot. TIA Jordan

Where are the great minds with their sage council and well thought out advice?

Do it!



I did that with my '94 (160hp automatic transmission pump) and it made a HUGE difference over the OEM plate in the OEM position.



I don't remember the exact numbers but I went from 139hp in OEM form to 271hp by pulling the plate out of the pump. It ran a shade hot... but I never do any towing with that truck...



You may or may not see an increase since you already have a #6 in there... but you won't do any harm in trying.

I did a custom plate for a friend for his 94,no smoke it ran 275 hp and 670 lbft torque. No other mods. A plate is much nicer. Especialy in California

Bob - those numbers sound almost EXACTLY what I got running plateless.

Not really... my '94 didn't smoke too bad until I slapped the 370's in it. Then when I started playing with DV's... :--)



My '98 holds its own for being pretty much bone stock... (OEM plate slid full forward... )

I'm sure the dyno operator will do whatever you tell him to do. However, be prepared to pay the consequences if the engine/turbo/whatever is damaged in the process. You cannot hold the operator accountable for testing the vehicle in the condition you provide it in. If he's good, he'll be carefully watching the EGT to try to cover your butt and his, but you can't blame him if he just drops the hammer and lets it do its thing. That plate needs to be in there. It has a purpose. Remove it at your own peril. I'll dyno your truck without a plate, but as always, the risk is your own.
