i got my dino-run today and my car was on a dynopack brake horsepower dyno. my mechanic told me that brake horspower is more accurate than wheel horsepower and that whatever number i pull here i can expect more on a regular dyno. Is this true?? what he said made sense and it looked crazy, they clamped these two machines on my brakes and ran it like that. anyone else use this dyno??

 

Actually you'll make less on a Dynojet 248C and probably even less on a 'Stang.

True.

 

I just dyno'd on the autopack @ Church Automotive today, so in comparison to a dynojet i should typically expect what ?

 

so your saying on the dyno jet i would make less horsepower? that sucks. anywayz how much does weather effect the run.. today it was like 95 degrees, basically hot as hell. im just double checking because i was disapointed in my numbers and was hoping it was because of contributing factors such the brake dyno and temperature. i guess ill put it back in the shop soon

 

Shawn has stated that his Dynapack will read/measure 10-15 hp higher than a traditional Dynojet.

quikyEG: You sound like you just want numbers for bragging rights. You should get a Clayton dyno then. A few months back when Turbo magazine did a dyno shootout using a 350Z, the Clayton measured the most torque/hp. Joking aside, you're not making less power. It would help to have had a baseline to compare to. Comparing #'s with dyno's across the country won't do you any good. Best bet would be to compare to others who have dyno'd there.

 

im not really worried bout bragging rights, im just making sure my engine was producing numbers that were up to what i spent on it. that is very true i should compare numbers with other people there, i just wanted to make sure everything was legit

 

what's your set-up and numbers

Those numbers dont look right at all. Did they do just a baseline, or they actually 'tuned' it? I would expect better numbers from those Church guys!

Just wodering, how much was the head milled, what head gasket are you using, and what is your total CR.

 

numbers seem kinda low...heh...

 

this isnt everything, but in terms of power:

B16 (bone stock block)
skunk2 stage II's
ITR valves, lightly port/polished head, milled .020
Skunk2 valvetrain
spoon headgasket
AEM CAI, JDM 4-1 Header, and mugen twin loop exhaust "

189whp and 116 tq via Church Automotive.

 

my baseline run untuned was 158hp. but i think its the dyno cause hes got a race engine he built and he only put down 192 and hes got stage 3 cams. but in all im disapointed, i thought i would put more down, i need to get a better header thats for sure.
