Re: Dyno Run Before Cams and After Cams (King Tut33)
So you gained 3hp ad lost 3tq going from stock cams to SS2"s?
I must have missed something in your post.

Re: Dyno Run Before Cams and After Cams (EKhatch)
numbers after are low. a buddy of mine almost has the same setup but with ctr pistons and is making well over 198 semi tuned. either whoever is tuning dosent know what hes doing or the motor is unhealthy (compression & leakdown test?). how much fuel pressure are you running? why do some of you guys run stock fpr's when running big cams and pistons? how are the vafc settings?

Re: Dyno Run Before Cams and After Cams (King Tut33)
Who is tuning your car ? What is your A/F ratio ?
Are you sure you have Stage 2 cams in there ?
I know your compression ratio (11.3:1) is a little bit low for running stage 2 But still you should be more than 3 whp.
You should be making more power with those cams and the other mods you added .

Did compression couple weeks back and got 240 across the board. I am not sure if he changed the FPR, but I was at 37 psi. As for the VAFC settings I know he started off adding fuel and then hit a point and started taking it out. They are a "Hondata approved" shop, so they might know Hondata but not sure about VAFC tuning. Updated with VAFC settings.

something is wrong, if compression, leakdown ect is good, and you are getting ample fuel, i dont see why your only gaining 3hp, did they pull any timing, i dont kno possibly tuning...
and why is their a dip in power and torque right b4 6000rpms......

Re: Dyno Run Before Cams and After Cams (King Tut33)
when your secondaries open at 5800 there is too much air. You need to open your secondaries much later, you need an rpm switch to run that.
or
your a/f goes hella lean when the secondaries open and kills your power, you need to add a lot of fuelin that area.
where's the a/f readout for the second graph? and your original tune was pretty rich too...

You guys need to read. There are no secondaries. The second time the A/F was done on a laptop, so no print out.

Re: Dyno Run Before Cams and After Cams (BeeBeeOne)
I put them in myself man. HO8IN and H08EX. They are Skunk2 Stage II cams or I was scammed by an H-T member I bought them from.

Re: Dyno Run Before Cams and After Cams (stevel)
hmm i think ur fuel pressure is way to low..w. all that air u need more fuel i say 50 psi or higher, check ur plugs..and dont tune the vafc yet..set it at 0 for everything and do a base run...something is deff. wrong..my set-up is not even close to ures and i'm making just a little less power..heres my dyno sheet..
https://honda-tech.com/zerothread?id=782960
-check timing
-comp test again
-check ur cam gears(some ppl actually mistake advance and retard)
-also i think u should try ur vtec @ 5200-5300 rpm..looks like thats when ur low cam stop making power..
and let us know..gl

Re: Dyno Run Before Cams and After Cams (BeeBeeOne)
Damn... maybe its the tuning? Cuz those numbers seem low. Too low, esepecially with all the mods you had.
You should try what everyone mentioned already. Good luck.

He tried different cam gear settings multiple times. I am sure those are fine. I know the timing is good too, he messed with that as well. I will be doing a comp test this week to make sure it is okay.

I can't READ lol I though tit was a GS-R.
Well then my second point still stands...he's running lean there I would think.

Re: (FerioVtec94)
What gap are you running your spark plugs at? The dyno graphs' look hashy.
More aggressive cams require smaller plug gaps from what I've seen. I like 0.035 to 0.038. Stock Honda for for BVTEC is like 0.044.

Nope, just the first time. I think I might go back to SS. As for the plugs I am running ITR NGK laser platinums now at .044 where as before I was running GSR NGK laser platinums at .056 I believe. So I did make the gap smaller with the new cams as suggested by H-T.

Re: (King Tut33)
Throw some ordinary Autolite 3294's in your motor gapped at 0.038 and see how your motor feels.
It's hard for the dyno to pick up the rpm signal when the motor has platnium plugs.

Two different dynos, two different days, two different tuners(I assume). You really can't compare the numbers between those two graphs. The main concren would be that dip between 5 and 6.

Re: (RacerZook)
New videos added. I am thinking part of the power problem might be seen in the second video. I don't remember my car smoking that much when tuning it before the cams.

Re: (RacerZook)
How does the car feel? Does it feel any faster that before the cams? Maybe your rings are bad, also check your valves.
You could do a compression test, then put some marvel mystery oil in your plug wells and do another test. If the #'s go up significantly your rings arent sealing like they used to.

Re: (Used2beAb16)
damn..thats alot of smoke..i'm thinking its the rings..well something is deff. wrong...only testing will pin point whats wrong though..no healthy motor should smoke like that..
