Thread: N1 vs 20V blog, ate TB screw, fixed... i think.

Exactly what I been holding back from saying.

Kinda scary throwing a car on the dyno and making pulls without a wideband. How do you know one cam/run was richer/leaner than the other?

Not fair jump to conclusions without having the AFR plot.

I believe Jeremys car has a wideband just not a plot from the dyno. Im sure he can chime in as to what was going on with the a/f during the pulls as im sure they were still watching the a/f ratio. At least I hope so. lol.

But as for drop in vs drop in you cant argue with the results whether its because it was causing it to run leaner than the 20v's and causing the increase.

Not just AFR, but timing should be slightly different between the cams.

sweet results here
fine tuning could always be done later on
keep them coming and keep them wanting more
ve-t............goodness

As he said, this was a drop in comparison! he changed the cams On the dyno. i think its awesome what he did.. sure there could be benefits for fine tuning both cam sets, but things like that cost time and time is money.

i agree tho i hope he kept an eye on the afr.

i would have loved to have afr on these runs, but as i said the wideband was broken. as with any test, it must be taken with a grain of salt. in any case, i have tested many different cams and seen minute differences in afr readings. like i said before, i encourage others to do their own comparison and post results.

the car is tuned to the rich side, dipping to low 11 afr at 7000 rpm or so. there is more power to be made, for sure.

i believe coheed conducted the test properly, the only issue is im assuming he went 20v low boost, 20v high boost, n1 high boost, n1 low boost, so the last numbers might not be 100% from heat soak, but the complete drop in test shows how the cams really perform, but your right thats scary without a wideband but if his tune was that on edge from before i would be worried regardless

Ok.

It's not like he has a dyno he can just go use whenever he wants for free..

Thanks again for sharing coheed.

A lot of factors missing here.... Regardless it is very cool that you are willing to test all these options.
