just finishing up the last touches of a 3.0L spec motor rebuild that i will be looking to get dyno tuned & broken in very soon. quick run down of what ive done- an early, big port with 90k on it when this project started that i took all the way down to the crank with a polish n all the plugs pulled and races cleared. machined the rods locally, had gamroth's magic head work, along with a set of his forged CP euro pistons, & honed my original niki's. gt3 rod n crank bearings, everything in the chain boxes is new, cams & rockers checked out sound, oil pump was good, cleaned and reinstalled. new rocker shaft hardware, wrightwood kits top n bottom. will reinstall the weber 40's i ran previous as ive run the fuch out of money, so no 46's in '13...
so, regarding the engine dyno what do i need to know/do to prepare? i have a couple local bay area options im considering for the dyno tune & break in. i do not know the particulars of the specific machines either shop has at this point. i realize my questions may just lead to questions from you before you can dispense any advise, so please work with me. any general info that might make discussions with the particular shops im considering more constructive would be appreciated.
as i understand it most engine dyno's will take the output from the clutch disc. or is there others that may mate to the flywheel? id assume they prefer to wear your clutch disk more than anything that attaches to the flywheel... the shops im looking into are both porsche specific, so could there be an opportunity for linkage to the crank? seems doubtful as the slippage of a disk or flywheel should be a good thing.
ignition? will i need to have all the entire ignition present so just 12v is needed at the starter? i imagine the 14 pin connector might still be utilized, and i will need to determine the 4 prong connectors for the tach, coil, & such. what should i know here?
oil? i assume the return line that runs under the bell housing is in play to be sure. but does the on engine oil cooler play a role? im very confused here, so should you have the time,, do elaborate. i have assumed a case of break in oil is mandatory, but what about a filter? is there a corking fee if i bring my own...
AFM monitoring? ive got a single 02 bung on one of my heaterboxless ssi headers and run single burns scrubble packed cans. should a second 02 bung be considered on the other header to monitor/tune each bank independent?
ive done a few searches and have read thru many a dyno threads here in the ERF and have found nothing thats suited my questions above. if yir aware of one, or other resources, please, do link here for my consumption.
why no yard work has been done in weeks....
