ive finnaly finished my n/a build after about a year and i just can't decide if i should upgrade to hondata or the extra money isn't going to get me far enough for it to matter. my set up is as follows,

j's racing cf intake ( itr version)
jdm dc 4-1 (2.5 inch collector)
2.5 inch carsound cat.
greddy evo.
skunk2 stage 1 cams (itr valve train installed)
skunk2 cam gears
skunk2 intake manifold
hondata intake manifold gasket
b&m fpr
vafc
chipped p28/ 9000rpm( kenji skunk2 stage 1 program.)
spoon head gasket
exedy organic clutch/ pressure plate
exedy 9.8 pound chromolly flywheel
competetion port and polish head work, with intake manifold and TB port match from alaniz, head milled to 11:1 compression with the spoon gasket.
stock bottom end.

with all this i got 180 whp with 120 wtq. and i just don't know if hondata would yield a significant gain over the chipped p28 or if i would be dissapointed after buying it. what kind of gains do you think it would make if any over the chipped p28..? how much better is it?

 

bump?

 

in my opinion no.....but hey that is my opinion....

skunk2 stage 1 cams aren't really much for an ALL MOTOR BUILD UP....

 

There was someone on this forum that picked up ~10 whp after switching from a VAFC to Hondata. I can't find the post right now, nor can I say that'd be the same result for your situation. If I do remember though, he also had S2-1's. If you're able to get your VTEC set where you want to with a good ignition map and your A/F is pretty well smoothened out, then it probably wouldn't be worth it for you to spend money on a Hondata.

 

well heres my dyno... don't know the a/f ratio but the vtec engagement is pretty smooth.. can barely tell where it engages on the dyno.
says flywheel but its actually at the hub which is basically whp its just dynopacks are weird is what sean at church told me.
