what's the next big thing for the K23? cams a turbo ??? we have tuning now so what do we try to get next? cams would be less expensive for sure but a turbo would give much more potential. what do we as a community try for?

bluecarbonfiber

cams have a decent lope.. i would be curious to see what a bigger one would do though

TheWrench116

maybe send a set of factory cams to BC and see if they would make a set of (random number here) for the community that gets no love. we could pool some cash to lessen the hit for R&D costs?.?

...carbon drive shaft?

bluecarbonfiber

carbon drive shaft would be nice.. wouldnt mind something that could really handle the TQ.. honestly if you want to make a good improvement i suggest a better TQ converter.. it will give you better response specially with all that HP and TQ we are missing from the slushbox of an auto we have..

wonder if the stock carbon drive shaft from the RL would fit the SHAWD of the RDX

protoRDX

Why talking about drive shaft, cams or turbo if the biggest issue of RDX has not been solved yet?? I'm talking about heat soaking. Now we can tune the Flash pro. If we would be able to bring down the temp on the IC it will let us tune our comps more aggressively. This would be the biggest upgrade right now.
I vote for asking Richie to accelerate the development of the liquid-to-air set-up for us.

can some one with flash pro data log this out on the highway to verify this is a major issue? in no /lo air flow situations I know all air to air intercoolers have issues not really worried about it if im not moving.

ive had no issues in extreme summer weather (110+), repeatedly. ETS and manifold gasket work very well.

if I ever repeatedly floor it with the hood open and not traveling anywhere... maybe i'll be in trouble.

carbon shaft will improve mileage, acceleration, possibly braking distance, etc.. and shouldn't have a prohibitive R&D cost.

bluecarbonfiber

our drive shaft is pretty light to begin with.. sean church states in this video its around 30/35 lbs
carbon fiber would be about 15/20lbs due to metal parts being added.. so that works to about 10hp gained due power loss.. a good torque converter can give you that maybe more and probably cost less.. 1000$ drive shaft vs 600$ tq converter..

I do like the idea of beefing up the transmission ATI in maryland is a reputable company that makes good parts.

ivan_baez

for heat soaking I would recommend a methanol injection kit, easy to use and provides excellent results! (10°C below ambient temperature on my RDX using a 50/50 mix)

I plan to go visit ATI when I get home as they are local ish to me. I did send a letter to brian crower to see if they would be interested. so I guess we will see.

from ATI


We are a GM based v8 racing company; we have no support or offerings for import transmissions.
The transmission if you can find someone to build one that will handle HP it will be the same cost as a rally cross manual transmission, they are 25K.
If you do find a transmission the converter selection will only be OEM components and never perform properly. Unfortunately this is the cold fact. Be not falsely told of “new” or hardened parts I have seen even in the v8 overdrive world a “hardened” part is only an OEM part that has been heated. This might make a factory part a small % better but will still brake and most of the time the heat treat was done incorrectly and the part is brittle.

bluecarbonfiber

IPT http://www.importperformancetrans.com/index.shtml will beg to differ.. i know they would need the existing tq converter to rebuild since they dont have cores but they rebuild it and its proven..

I took the letter from ati as more of a F#ck you get lost type
thing.

bluecarbonfiber

i see it that way too.. just by the beginning of the letter.. we are a GM based V8 racing company so how dare you! haha some people still live in the past that unless its a v8 it means nothing to them which is pretty narrow minded and shows that they are just uncapable of working on anything that might require neurons..

I also wonder if the RL carbon shaft would fit, that would be cool.

bluecarbonfiber

it looks close... http://www.ebay.com/itm/05-12-Acura-RL-AWD-Carbon-Fiber-Drive-Shaft-OEM-LKQ-/190998397618?pt=Motors_Car_Truck_Parts_Accessories&fits=Make%3AAcura%7CModel%3ARL&hash=item2c786442b2&vxp=mtr#ht_3077wt_959
for 390$ its almost half tempting to see if it does fit.. you could always resell if later if it doesnt.. wonder how light it really is in comparison

ivan_baez

here are another two, a little bit cheaper:

bluecarbonfiber

someone buy one and compare =)

shivaswrath

I just posted above, if we do this, it's about $700 for fresh set over to get reground...is that the only R&D cost, or are we talking literally a new set of cams (that might be cost prohibitive for a company to do).

It’s about 65K to do the tooling to make the cam core so we just have to justify the demand before committing introducing a new cam line.

ok that sounds good. what kind of interest would it take to make a production run at this? albeit a small run but a run none the less.

Joshua,
Unfortunately we do not have any cams available but we can regrind your factory cams for $495 and 2 week lead time.

hello my name is joshua fletcher and I am the proud owner of an 08 Acura RDX Tech with SHawd. I have a majority of the equipment available for it from the aftermarket and am interested in what is next. I was hoping you would be willing to develop a set of cams for our under appreciated platform. thanks for your time sincerely Sgt fletcher

bluecarbonfiber

there are plenty of stage 2 and 3 cams out there for K series motor.. its just a matter of matching which would work best

TheWrench116

iTrader: (1)

I was under the impression that the cam lobe setup was different then the rest of the K family. that would be great if they are compatible.

Slow98teg

They are not compatible. Rdx's do not have 3 lobe cams. They have single on the exhaust and two on the intake. k20a3 and the k24a1 share similar cams. I believe people have already tried to compare the two when the rdx was first released. No go.

TheWrench116

iTrader: (1)

ARG... well there has got to be something that we can do. if I remember the heads aren't compatible either so we couldn't swap them either.

bluecarbonfiber

honda CRV is a dual lobe setup they make cams for that i think

TheWrench116

iTrader: (1)

if it works in another K series I believe we are sol. the link you posted was for a 3 lobe setup. for a k20a3 and k24a1 as stated in the product description.

bluecarbonfiber

no it doesnt read it again

well I sent them an email lets all hold our breath or not. cause if they fit ill buy them might as well with the intercooler coming off anyway right?

bluecarbonfiber

i sent them an email too.. just to see

TheWrench116

iTrader: (1)

maybe if everyone did that ^ we would get somewhere... :\

Slow98teg

Skunk2 cams suck. Fast ramp rates cause tensioner failures. The wear fast as well. I've personally seen grooves in the lobes and it wasn't from oil starvation either. Not even 10k miles on them.

TheWrench116

iTrader: (1)

what motor did you have a tensioner fail on?

Slow98teg

Me personally none. I refuse to run any skunk2 parts. Countless have failed via skunk2 cams. Browse over on k20a.org about their quality. They've made good power but don't last. Cheaper Chinese metals are used in the cores.

TheWrench116

iTrader: (1)

OH the factory tensioner in those motors is junk they fail on aftermarket cams of all kinds not just skunk 2. as far as their cams go I was unaware of those issues. definitely something to look for if they do in fact make something compatible with the K23.

Slow98teg

Not on IPS, Drag Cartel, Hytech, Web or even Brian Crower. A lot of big racers use oem tensioners with these mentioned cams with no problems. They see 10k rpms quite a bit.

Lanesky_OH8RDX

Any thoughts on a FMIC setup? That would help temps significantly. Also you would want to stick with a cam design for turbocharged engines due to longer valve duration. N/A cams could possibly degrade performance rather than upgrade it.

bluecarbonfiber

not much room for piping a FMIC.. plus youll get some turbo lag too
