yea, but question.

are you guys gonna disassemable the engine? or lift it out of the bay?

how much labor can you expect to pay on this job (hours) ?

jdmspec333

the heads are already out of my car, i own a repair shop and i'm doing all the work myself!

mishar

Well, if money is not a problem it does.

Speaking about hollow camshafts, the difference is absolutely immeasurable. That hollow part has very small diameter, it is not much of difference in weight, especially compared to the rest of rotating parts and cams are twice slower than crankshaft.

Inaccurate

well, since we are pissing in the guys Cheerios... I just thought of something.

I don't think the S cam has longer duration. It is a hard fact that a longer duration cam produces peak HP and peak torque at higher RPM than a cam with less duration. And, from the published specs for the TLS, it produces peak HP and peak torque at the same RPM as the regular J32 cam.

jdmspec333

well, according to the 07 tl service manual (oem), between the j32 and the j35, the lobe heights are different. now i know we discussed this before, the profile largely depends on the duration and lift, but stating that it has different lobe height, its gonna be a different cam altogether. like it was also stated before, honda likes to interchange parts between platforms. so why would they (besides the fact that they're hollow) use an entirely different cam with different profiles (the duration and lift still unknown) in a car with basically the same engine (just bored or stroked) when the old cam is tried and true? oh and before the cams are installed, i'm gonna have the machine shop figure out the lift and duration for both the cams (type s and non) before they are installed. this will benefit us all because i don't think there is anyone doing a cam only install, so dyno testing after the few of us doing the cam install will be worthless for a baseline cam comparison. oh yeah, is there a v6 adjustable cam gear out there? i've done a few adj cam gears on stock cams, and they made a small, yet noticeable difference. (sohc and dohc applications)

Inaccurate

As a suggestion, have the tech to measure the duration at 0.050 inch of valve lift. The total duration of the cam measured at the plateau (0.00 inch of lift) is pretty much meaningless.

TL-S cams fit.

jdmspec333, you should def measure them, that way everyone will know for sure if they fit, no more hearsay.

blackura ny, you have to removed the heads, not cheap...you'll need a new headset also.

There are no V6 cam gears out there and to make an adjustable one, custom made, is over $1k from what I have been told by others who have tried.

jdmspec333

ur does cnc machining. if they mass produce it, i'm pretty sure it would sell. plus it would be good for multiple applications.

UR will make cam gears for us, i called and inquired, in fact they are about 15 mins away from me, but they said it would cost at least $2,000 to get the first set made.

johnny--2k

AHHH!!! $2,000 for the initial? That's insane!

jdmspec333

everybody pitch in a hundred bucks! we'll have two grand in no time!

3rdGenHybrid

for cam gears....or cams?? im hoping u meant cam's

jdmspec333

adj cam gears

3rdGenHybrid

2g's for adj cam gears....?

jdmspec333

well its two grand for the first initial set because they have to program the machine, and dial in all the specs. they would probably go through a couple chunks of billet before they get a final production ready peice. it's like we're paying for r&d. the peices that come out after that would probably be around 150-200 each

CleanCL

iTrader: (4)

basically.

Eoanou

We should all pitch in for the cam gears, that would be a decent mod to do. Also I'm surprised you didn't port your Throttle Body Ussi, since you were messing with the heads, it would have been worth your while.

$50 a person... 40 people. and we get the first 40 produced

i would be in.. .we should make a poll and get back to UR. they are right near me in LI, NY

jdmspec333

actually, it would be 50 a person, with 40 peoples, and one set (or gear) would be made... then it would be the 150-200 each gear thereafter.

HQTL6SPD

i wasn't planning on it, but if for $50 with 40ppl, then, i'd be in! $2000!? fogetaboutit

Eoanou

So if UR sold the cam gears for 150$ it would end up being $200 for the first 40 customers to make up for the $2000 r&d and then $150 for everyone else. Someone make a thread.


I didn't know UR was so close to me, I'll have to visit them one day.

jdmspec333

well someone should go and find out. how much would it cost to make (x) amount of sets fo a certain price including the r&d. then we'd all split it evenly. we'd send the money directly to ur to build the pool up.

I have a good relationship with UR. I could get this produced like I did with the Acura TL stock size crakn pulley. However, I would need to see a list of at least 25 ppl that were really interested.

Black_05_TL_6SP

This actually sounds pretty interesting. I loved the set I had On my Prelude. If any thing, it looks really cool when you cut the end of the valve cover so you can see them!! I would be down for this. Jason

i'm in! start the list! do it! cmon do it!

So what performance gain does the cam gear gives?

Does any of this info apply to the J30A4 03+ Accord engine? If so, I'm in.

i think we should start a new thread for the UR cam gears, this way we dont hijack the port&polish


i wanna see the results from P&P and TL-S cams too!! dyno sheets PLEASE!

I hate cars

You guys are forgetting the cam and heads should be matched as a pair. If the heads are being ported, the cam will make a bigger differnence if it complements the heads. I would definately go with a bigger cam if I ported the heads. You also have to think about emissions. While bigger power can be made with more duration, it effects emissions much more than higher lift. Now on a larger displacement motor like the 3.5L you could get away with a proportionately longer duration without hurting emissions.

As for polishing or not polishing, these cars are fuel injected, not carbureted. Polish the hell out of the intake. You don't have to worry about fuel fallout like on carbureted motors. The fuel injectors are aimed right at the intake valves. Not only that but this is a 4 valve motor. You're going to have all the velocity and such that you need.

50-60hp is not out of the question NA and the gains will be larger for the already supercharged cars.

What's the point of cam gears on a stock motor? They allow adjustability. Why would you need to change the cam timing of a stock motor? If using aftermarket cams maybe but otherwise they're a complete waste of money. If you believe these work, go buy that tornado air thing while you're at it.

i agree, i was just waiting for someone to post all the advantages of the cam gears.

mishar

By retarding camshafts you gain some power at higher rpm while loosing some at lower rpm.

I hate cars

Does the TL really need less low end torque? It's sort of lacking in stock form.

HQTL6SPD

+1

i was hoping more torque all around

BLACKURA_NY

iTrader: (6)

so if ya change just the cams, we are looking at low end torque loss? that wouldnt be worth it to me.

ussi, you still in the shop? getting it back soon? im sure we all wanna see those #'s.
