Quick question, what gear do you guys do your dyno pulls? just wondering what is the best gear to go. Will it make a difference doing pulls on 3rd or 4th?

 

under 300 ish i was doing 3rd.. but as i got over the 300 mark the tires were spinning on the dyno.. over 350 ish i was just making a smoke show!

but when i do hp chart it was in third..

but make sure you do some street tunning. if this happends or put on some drag radials! Or else the tune wont be right if you do hook up on the street!

 

burnouts on the dyno? my map is made on the streets but there will be no heavy boosting on the street/track for now, I have a really skinny oreily axle lol

 

4th gear.

 

ya supposed to b 4th gear pulls

 

but will it make difference doing 3rd? slight difference in power band?

 

4th gear.. that is your 1/1 ratio and will give u the best average result... 3rd gear is shorter so you might get an inaccurate number

 

i dunno.. but i can tell you this..

ive had my car dyno tuned in 2 places. and dynoed in 3.

everytime ive made a dyno sheet they have done 3rd gear, as i would assume many many many others do

 

That's what I thought too.

 

Hmm

I do not know.. Ill ask my tuner as to why he uses third for this vs 4th.

Maybe for inflated numbers.. i dunno.. I woundered also if its for saftey 4th gear ur spinning those tires pretty fast on the dyno..

Im Stumped!

 

alot of shops do it on 3rd gears they say you get the most power rating. but they also say 4th gear is the mos accurate reading. but when you dyno tune it should be on 3rd gear. lol i would just do 2 pull in 3rd and 1 pull in 4th see how that goes.

 

4th gear like said before 1:1 ratio. 3rd gear multiplie's tourqe witch yeild's higer hp # and tq #. great for dyno queens.

 

Fourth gear.

 

That's exactly why I thought 4th would be optimal. 3rd would read high, 4th would read accurately, and 5th would read low.

 

question about the coilpack, which wire do we clamp that thing for the dyno? i went to the dyno and he couldnt get it to read torque coz he doesnt know which wire to clip

 

i dont remember my tuner ever doing anything to my coil pack...could be wrong though..

 

when i got street tuned today he just hooked a thing to the exhaust and another thing to the obd thing then another to the fic lol felt like a robot

 

^^ thats for datalogging, at least he got some tuning device to do the street tune.. but yeah there's that thing that is clamped on the one of the coilpack wires, i guess each dyno is different

 

you know ace now that i think about it my tuner would have to have some way of getting the rpms

 

4th is a dyno gear not 3rd ur just playing with inaccurate numbers in 3rd gear
