what's a normal dynopack 5000 # for the S with I/H/E

Sideways

The Church Dynapack dynoed several year '00 stock and they averaged 213 rwhp. Intake, headers and exhaust might add a few ponies to that number but usually not above 220 range from what I recall.

AP2s dyno on church's dynapack dyno for about 225-230 stock. I've seen I/H/E dynos on church's dynapack for 240 range.

are we talking about dynopack 5000, not dynojet? just making sure we are talking about : http://www.dynapack.com/dynapack.html
this dyno has 350z with I/H/E dynoed at 220.
wouldn't a 4.44 FD mess up dyno reading? if I am not mistaken hp # is measured as some factor X torque X RPM, and most dynos are just measuring how much force needed to stop the wheel from spinning (aka, torque).

Sideways

As long as the ratio is entered correctly gear changes will not make a difference in the reading.
A stock AP-1 with 4.10 rear end gears would have 5.521 as a ratio using 4th gear.

If 3rd gear is used then a ratio of 7.044 should be used, if 5th gear is used then a ratio of 4.618 should be used.

Ratios can be obtained from http://www.turnzero.com/technical_resource...gear_calculator

TCF should be zero.

hey sideways, so on a dynapack a 350z with i/h/e should make more than 220?
I am trying to figure out my dyno result, my # is low compared to what an S should make on dynapacks, yet my compression is 210s across, leak down tests came clean. I was told a stock s2k should make about 170-180 on dynapack.

Sideways

I have never seen a healthy stock s2k put down 170-180 on a Dynapack. 200 to 240 is what I have seen. 170-180 sounds like a Mustang dyno.

As for a 350z check out these threads:

thanks sideways
umm, this dyno reads 350z's # low too. by ratio wise 200s on the dyno I've been using should be sth like 230s on other dyno...
it's not a mustang dyno for sure. is there anyway the dyno could be configured wrong? or does dyno loose accruacy over years? speed seems to match.
wait I just remember sth, this particular dyno was mostly used for 4wd cars, I am no expert on dynos, doesn't 4wd needs different configuration?

That completely depends on which header and exhaust you have. If you have dc header and comptech exhaust, you'll probably have zero gains over stock.

I dyno'd on Church's dynopack at 232. '05 with only intake, tp, exhaust and VAFC (version 1).
