Well I was at the dyno yesterday to see if all my work and cash has payed off. When I started my car was at 150whp and when we finished it was at 172whp with max torque at 116. I would say the tuning time was well worth it. The only real tweaks we made were moving the base timing to 18 degrees and messing with the fuel maps in my Hondata (my buddy was there with his stage 4 setup). The cam gears we found to work best at zero for both intake and exhaust side for the skunk2 stage 2 cams. Any adjustment on those would rob Peter to pay Paul on the power curve so setting it at zero left a nice smooth curve. From a little after 8000 rpm to 9500 rpm is where the power is (stays between 168-172whp). The torque remains fairly flat throughout the whole chart. I will get the chart up once I get around to scanning it in. Also got good video, but again go to find time to get it posted.

On another note, I dropped the Act SS/HD, ITR Flywheel and LSD in my car this past week end. I must agree with those who said it in the past... LSD RULES!

 

Nice. What did you pay for LSD?

So if your cam gears are both at 0, are you going to keep them for possible future mods, or just go back to the stock cam gears?

 

What was your VTEC point set at ?

Also, how much timming advancement did you have between the 6000-9500 RPMs.

 

Those are some good numbers going on stock compression. I think with ITR pistons and a little more tuning would bring you very close to the 200 w.h.p. mark.

Is the header a regular DC 4-1 or JDM? A good header with 2.5" collector would free up some more top end too.

 

i think there must be something missing or some better tunning is needed, my friend got 168 hp out of his b16 with the stage 1's! stock compression and no hondata. i think you can get a lot more power out of you setup.

 

Get rid of that header and get a real one

 

200 whp is possible with the Stage 2s in a B18C with raised CR and a very free-flowing header/cat/exhaust setup. Not stock compression with a 2.25" exhaust setup.

Stage 1s make awesome numbers in B16s because the cams are well-matched to the long dwell at TDC.

yeah but never the less, with the larger displacement and more aggressive cams i'd exepct much more than 4 hp

 

"Stage 2's make 5 more hp than Stage 1's." Quote from Skunk 2

 

The vtec point was set to 6800.

 

yeah but the gsr starts with 10 more hp so if you think abou it he should be getting at leas 15 hp more

 

If he gets rid of that header and gets a real 2.5 header he will see significant gains in vtec. As for the cam settings, all motors are different and obviously his likes 0,0.

 

Sure I could have achieved 180-185 or maybe better with what I saw from messing with the cam gears but I chose to have that power in the low in middle of the RPM where I use it most (a nice smooth upward curve). Not on the top. And as for the vtec, it is set correctly. The dyno proved that.

 

I love how everyone criticizes dyno #'s.

Good work RedTeg95, given your mods, and considering stock compression.

I'm not trying to be a dick or anything, but if you don't know what you're talking about just be quiet! Most larger aftermarket VTEC cams require the VTEC crossover point to be set a well over the stock crossover point to yeild good gains. And from what I've seen, cam gear tuning in most cases just moves the hump in the powerband up or down the rpm scale. Having them set a 0 probably gives him just the right balance of low end and top end that he is looking for. You need to learn a little more about what you're talking about before you start criticizing someone's hp gains.

 

yea i feel like you should be making more power --- jdm 4-1 and test pipe or carsound will probably open up alot. itr pistons will do wonders too.

Just retune it,don't go out buying headers and pistons just RETUNE it.The jdm 4-1 isn't gonna give you an extra 25 ponies to the wheels over the 4-1 your using. But not bad for a car thats 7 years old.

 

The primary lobes on the Stage 2s are larger than stock as well as the secondaries, so they make more power both before and after VTEC. Bigger primaries means you have to move the VTEC point up. You do not "throw your midrange out the window" by getting them.

Your "knowledge" or rather the lack thereof is in question because you posted in an argumentative manner and spell like a 10-year-old.

And no, you do not make some very strong points.

 

I have only one suggestion as far as freeing up some ponies without buying a new header, exhaust etc: your stock cat is probably clogged up with all of the smog particles that it's collected over the last 7 years and restricting exhaust flow.

 

If his header is the little rinkydink dc 4-1 it is a huge restriction, period. It will not flow a big cam like a 2.5 header can.

 

Again retune it,I've seen GSR's with ITR cams and no 2.5 run 175whp.

 

Stage 2's are nowhere near the same size as ITR cams. Can't compare. Bigger cams need to breath.

I wanna see the graph.

and how exactly would you know that? he said it's just right for his car. were you there when he tuned it? considering his engine has stock compression, stock head, regular DC header, i think the numbers are pretty good. in the future when he modifies his engine he will realize even more gains than if he had gone with the stage 1's in the first place. but still, a 22 hp gain is nothing to sneeze at. he'd probably leave you in his dust
