Thread: Triy bigtube vs regular tube

N1 cams and excessive plenum with n1 runners

Thanks, I'm curious to check see the difference in size between the 2. I check but not sure which one are you guys running.

Will the power gain this much differences on stock intake mainfold?

very good tq curve

wher do you rev to? i was thinking that with the upgraded intake you would have held the power for longer. why does it drop off so fast?

peace

9100 rmp and we just fixthe fuel map not the timing so their could be little more gains

It also depens on how you strech the graf inthe dyno

is it just me or, do the tq numbers seem a bit low for those hp numbers? both red and blue runs. i would expect to see at least mid to upper 160's tq, for mid 230's whp.
pretty nice gains across the rpm range though.

good to know the bigtube has some gains....

Remember it depends on the bored ..think..

congrats on the gains bud, i have a big tube version for my 12.5:1 86mm build, i think the higher compression 86mm motor will also show better gains with the bigger primaries of the big bore
