Dyno: Skunk2 Pro3 vs Pro2 vs BC5
 

Installed some Pro3's last week and did a rough tune last night. Fuel is 90% tuned, could be better, very little ignition tuning (used my Pro2 map as a basemap), no cam gear tuning, left them at +2/+5 where the Pro2's liked them.

Both the Pro2's and BC5's were fully tuned, fuel, ignition, and cam gear.

*ignore the run titles, forgot to reset them*

*note* BC5's were on when I had a 65mm T1R, only change in the setup

I did not use a degree wheel to install them, was in a time crunch, but as a side note, I wouldn't run these cams at 0,0 unless they were degreed properly, they're big, if you are in a hurry, you can always advance the exhaust cam to help prevent V2V and P2V.

BTW she idles and warms up like stock.

Wow, the Pro3's absolutely killed the 5's by basically dropping them in!? Great info, thanks again! https://honda-tech.com/forums/images/smilies/emthup.gif https://honda-tech.com/forums/images/smilies/emthup.gif

Skunk2 cams have proven themselves once again

Question.

Do you think the BC5's would have improved significantly if they were dyno'd with the 70mm T1R system? Also, was there any room to degree them?

That's what R&D gets you.

Re: (SMSP)
 

i tuned a car last night that made 240.8 on pro2's.......we were talking about how the pro3's would act last night in comparison. this makes me very interested

Nice numbers https://honda-tech.com/forums/images/smilies/emthup.gif Interesting comparison between the Pro 2's and the Pro 3's.

What's funny is that when we were still running our B series engine program in Project Beta, we were only using Tuner Series Stage 3's. Wish we would have had our Pro Series 3's back then lol

Thanks for the information

Re: Dyno: Skunk2 Pro3 vs Pro2 vs BC5 (mar778c)
 

But,but,but, it's only 12-1 you are way over-camed, BC5,s and Pro 3's will never run on that motor. Even Pro2's are too big, the biggest is a BC4, I know, I have read it on H-T. https://honda-tech.com/forums/images...es/emsmile.gif Nice job, retard the IN. a hair.

Re: Dyno: Skunk2 Pro3 vs Pro2 vs BC5 (DonF)
 

Any idea how Jun 3's compare in this same motor?

Was 12:1 the actual calculated ratio or just a certain shelf piston you used? How big did the chamber end up being?

I think the Jun3's would get absolutely owned in this comparrison, but I could be wrong.

OTS CP 12:1 pistons.

I did not CC my chambers after the work was finished. Judging from the ignition timing I can run @ WOT, I'm guessing between 11.7-12.0:1. Chambers were only enlarged around the valve reliefs to aid in cylinder filling and low-lift flow.

I did a before/after comparison with the Pro2's. Picked up ~4hp peak, a couple here or there in the midrange, nothing significant. I'd imagine roughly the same with the BC5's, probably close to 230whp.

I'm confident I can push into the 230's with a better fuel curve an actually touching ignition/camgear timing.

I'm excited to see how much power this motor can make with an actual 2.0L header and a good IM/TB setup...not bad for a cookie-cutter build https://honda-tech.com/forums/images/smilies/emthup.gif

Re: (Turbo-charged)
 

off topic but, $450 for my set of Pro2's......... https://honda-tech.com/forums/images/smilies/emwink.gif

Re: (b20vtech)
 

im supprised there was such a large difference in your dyno in the favor of the pro3's when b19 did the same basic comparison with a similar motor and the pro3's didnt really outperform the pro2's at all. https://honda-tech.com/zerothread?id=1786276

i mean i belive what i see but this looks more like a pro1 vs pro2 dyno comparison to me....
