i swapped in some GSR cams today in my b16. i dont have money to waste on a dyno, so i used my laptop to get a "ghetto dyno"

i wasnt expecting any gain, since they're supposed to shine for FI setups. however, i did see a small gain that i can enjoy until i go FI.

comments welcome.

 

What did you use to measure the times?

 

Yeah, how'd you get that?

 

And I ask again?

 

nice to see you got alittle somethin out of them, try installing a ITR exhaust cam combined with boost... supposed to be beneficial for helping power production at higher levels from 8-15+ psi

 

i use a few components connected to my speedo sensor, and then connect it to my laptop's soundcard input. then i record it as a wav file, and process it with a program that tells me what frequency the sensor produces at what time, then i import the data into excel and apply a simple multiplier that converts frequency to mph, then use excel to graph the results.

thanks for the comments. the only reason i went GSR over type R is because of cost. i'm in the middle of buying my FI stuff and i was short on funds

 

alright Egon, I'll remember not to cross the streams next time...

 

haha i heard about that ghetto dyno about a year ago always wondered if it works
looks like it does rofl

 

well i think people have done it various ways. my original plan was to make a real dyno chart in excel, but i didnt trust any formulas for hp and acceleration, so i kept it simple and accurate instead. there's really not much to it. i love how easy it is to make a run and see results.

 

bahahahaa
