Hey guys, does anyone know which intake manifold these cams were designed for/work better with? I have 2 conflicting threads here. The dyno with the cams matched to an RBC make LESS power than the dyno with the cams matched to the PRB. Id like to know why, maybe im missing something and you guys can enlighten me.

I have full boltons+kpro as well as RDX 410 injectors. I have these cams and an uncut RBC IM sitting at home. Thanks

Ask drag cartel. 98% of the answers you will get from people on here are going to be from people who have "read" these cams work better with this setup as opposed to another.

Not to mention the fact that one of those dynos was on a Dynapack and the other on a Dynojet with two different motors(K20A vs K20Z1) in two different cars(EG vs DC5) and two different climates(SoCal vs Baltimore). Dynos are tuning tools, not a method to judge which car is actually making more power. That is what the track is for.

So I contacted Drag Cartel and I Spoke to who I believe was Jeremy....he said that the DICs were designed around the Civic Si which obviously comes with the RBC intake manifold. So the optimal setup will be the RBC+DICs.

Just bc they are desigend for a RBC dosent mean tha the RRC will make less power. By desigen they are very simular, I have had the PRC, PRB, RBC, RRC is my current only k24a2. I have made more power HP/TQ on the RRC then any other. I would think the same concept will apply to the the DIC cams. The more air and volocity they air enters the head will result in more power.

I had drag cartel with RBC, ,but down the road I went back PRC, due to fact that PRC gives better lower power band, drag cartel dic when first put in on prb. Had a great mid power band.....
I think it all comes down to how it's tuned to your engine.

Hahah, I know what u saying dumb to go back to PRC when RBC makes more power.
My car is a daily commute car, not sure if u had u var up in dyno to get it tune.
Take a close look at lot of dyno sheets.... All that power everyone talks about comes into play around 7000rpm.
It be stupid wise to rev that high all the time just even drive down market or etc.....
PRC has better low Mid power band. Which make the car have more useful tq,HP for just daily cruise ...
I have been on dynapack three times and have actual proof to back up claims.

Lol..... Ok stick to ur prb. No problem...I have nothing against anyone...tuning a vehicle is to tune the vehicle to your needs...don't just always go by what you read on other post....every product you see always have .likes,nd hates from different members..
My info is off from my own install and actuall time on dynapack.....so please no need to make fun of my review...

That yr ago, well let see my car was at church automotive getting k24a2/k20 with built bottom, and drag cartel cams, getting tranny with all New carbon synchro, type r 4,5th gear.....PRC,RBC, back to back dynapack tunning session....
 
#13 ·
So if you think that's still funny.please enlighten me on your own actual test ... Not just based on what you read....
Many people get different results even if they use same product....
Don't just go off post that talks about PRC being same as prb !!!
Do more research and also see results of PRC ..

PRC is like throttle body spacer.
Majority of the members will talk crap,saying waste of money,it doesn't apply to fuel injection system..etc..
But many of them will be the ones who has never actually. Tried product... And people who have tried ,u will see .mix result.... They have actual proof of seeing gains on dyno..
But just adding bolt ons and gain 3-5 HP. You won't see your car knock off a half a sec or so...
Don't always rely on forums....
AsK ur self why did Honda R&D.design PRC when it same as prb?? They just stamp PRC to fool consumer on their Type r badge?? ,I doubt it!!!... Every single part on the dc 5 type r was ground up built just for type r.
And type r is a track car. Not a muscle car. PRC was design to work in all power band. Unlike rbc which is a hell. Of a gain. But t lacks on lower and lower mid band. .. In track you use more lower power band than higher rpm. Unless it's just a quarter mile straight run way....
$50 you can find a PRC, it's just a simple cheap upgrade. .
 
#17 ·
Damn... yeah I already bought the RBC and its sitting at home....so if I put the rbc and cams id loose a lot of low end but gain a lot up top....but if I found a prc intake manifold id most likely get the best of both worlds between rbc and prb
 
#18 ·
Not loose.,...I'm just saying each design has their own advantage over the others..... When manufacture design their intakes....to shine more on high power band u have to sacrifice the lower... Same goes other way....
My point is that PRC is not better than RBC. They are both great.. But they have differece ......
 
#19 ·
Prc won't give the best of both world.
Will give better than RBC. But in the mid upper. RBC will outshine PRC...
This is my opinion,... Just ask ur self.... How often you rev your engine to6500 rpm in 1,2,3 gear?
I rather have more tq in 2000-4500rpm... To get me around town....
 
#20 ·
Right...I just don't want to put on RBC and be disappointed. But ive already spent the money and everyone has already told me to go RBC + cams so I will and if I don't like it I can always go back to PRB or try PRC
 
#24 ·
Everything you say makes very good sense. Thank you for the advice. Yes I will be installing my Drag Cartel Drop in cams along with the RBC at the same time as well as getting it dyno tuned. I cant wait to see what the motor will do....I will also be replacing my short ram intake with a cold air intake

I believe I made about 230HP 168tq on k20...on dynapack..
But I'm running a oem type r complete exhaust system.... More power can be gained with race header.and exhaust....

Once you done try sAve up for a clutch....
I personally like clutchmaster fx 100....
And straighten motor mounts.
I tried the after market ...but it's just too much vibration....
And torque damper. Also , just too much..
I did some research and found out mugen. Made motor mount....
Oem quality and comfort... But not much improvement like the Other polyurethane mounts..
And mugen set doesn't come with rear engine mount. Like other brAnd..... I ordered a hardrace rear mount only...
They use rubber like one but littler more stronger rubber... And it seems like a good combo.... Had little vibration but after about 2 month or so no vibration at all.. . other poly mounts claims after it settles in vibration will decrease... .. It's just all b.s from my experience...... Had them for like 6 month .and during that 6 month I hated them.....

If u have any question AsK, maybe I can help.
I'm not an expert or mechanic... But I did lot of try and error... I can give u a personal experience on item that I have tried..
Many thread I read . many great info.... But I just see too much people talk non sense ,when they haven't even tried them for themself.
.
I myself still in process Seeking out for that last drp of juice.. But at same time keeping my car CA emission standard.
My next goal is to seek out type r upper cylinder...

Lot of co out there great port polish etc....
but during my early yrs in 90s found out many out ther who port cylinders.... But not up quality proven result....
Type r cylinder has only the intake side hand ported by Honda tech who brought us type r!... I know compare to some other not much better... But I know for fact it's proven and oem quality of type r badge...
Some will say why the hell. You wanna upgrade with oem??
K20.org has a cult who worship oem swap.... And proven data ... And most important. Oem quality and realibity. That we all came to love about honda

Tuneing a vehicle is to tune to ur needs.
I just see no reason why not to believe people who actually have tried item...you put a same part on same engine.. And possibility of getting different result is very high.
If I'm low on budget

Like many others here I trust my butt dyno... Haha.
 
#31 ·
I love honda for that reason too....simple reliability....
im looking to make around 230hp....i already have headers and hasport 88a motor mounts with a torque damper...

This graph is taken from another CRSX thread and it shows very minimal loss of mid range power between 4200-5800 RPM. If you look between 2500-4000 RPM it shows an even smaller dip in the powerband that should have no noticeable effect on power delivery. IMO, which is not the same as everyone elses, that small dip in those two areas is well worth the almost 20 HP bump this dyno shows at redline. It appears those little dips only equate to about 4-5 WHP which you would never notice in part throttle driving.

Dyno was taken from this thread.

If you read the thread it does say that the PRB and RBC tunes were done by different tuners so that could account for some of the losses and some of the gains but this is just visual support to help you make your decision.
