Hi,


Has any1 with a 2004-2008 Acura TL 3.2 put in the 3.5 2007-2008 Type-S cams in ?

Dyno , driving feel, cam spec difference.....


I have a 2005 Acura TL I'm planing on doing the IM/tb 3.7/zdx swap and do the 3.5 type-S cams upgrade.

Thanks,

 

we've named them "Hype-S cams"

 

Haha, I was going to ask the same question as TLOHTL.

Are they really that overrated Justin? I've done a ton of searching around and never really found anything (install guides or results for that matter).

 

well, they are hollow and lighter.
but I dont think the lift duration is that much aggressive.

if you're going to spend money to tear apart your engine, might as well go for a much more aggressive cam.
like the bisimoto reground cams.


these 2 threads are a nice read:

that is correct.

IMO, the only reason to upgrade your cams would be to allow for significantly better tuning opportunities. Going from base to type-s cams isn't going to give you much.

Not to mention, if you are planning to go with 3.7 mani/tb, etc. then you're going to get a lot more out of the car with Bisi cams that are going to have a truly more aggressive profile where you will actually see power gains. And again, a lot more room for tuning.

For a while I was contemplating stage 1 bisi cams but given all the rest of the work I've done to the car and with plans to port the heads and beyond, I think Stage 2 is the way to go as long as you can tune it.

What i'm saying is, really think about just how far you want to take the modification of the car before you start playing with cams.

 

Without knowing the specs on the Type-S cams, I'd guess they might be good for 7-8 horsepower on a 3.2. At $450, not a horrible value *if* you can change them yourself.

 

No one has done a before/after dyno. I'd say you would see a decent gain with them, but at the now increased price of $450, it's not all that worth it. I was 99% sure on them (wanted to stay OEM) and when I went to double check the price before I bought them, they went up 50%.

They are hollow and have more lift/duration than the stock cams. Paul NVA-V6 said the lift is 0.1mm higher than the stock 3.0/3.2 cams, but have a decent amount more duration. He said the gains would be worth it as long as you port the heads. I believe one person dyno'd on his 5AT J33. However, he did the TL-s cams/ported heads/11:1 CR (up from 10:1) and gained ~35whp if I'm not mistaken. Obviously when you combine mods the gains increase, but those are serious gains. However, I've never seen the dyno so I can't say for certain. TL-s cams for $450 or Bisi for $710... You make that choice.

I_love_cars hit it on the head. Decide where you want to go with your car. Once you make that decision, it will be an easier decision.

 

The lift is maybe 0.001" - 0.0015". Really, it's minuscule. On an N/A car, I doubt the gains would even be that much. And that's a LOT of money for those gains on this car when you can get PCD's for much less.

 

True, but if you've already got all the standard bolt-ons, plus the 3.7 manifold/TB swap and want to stay OEM and N/A, it gets even more expensive to make power. People pay $1,000 + for a catback that gets maybe 7-8 whp.

I personally wouldn't do it because I'm not leery of going with the Bisi cams, and that's the road I'll be taking, but I can understand someone being concerned and wanting to stick to factory grinds.

 

Sure, but there's just a point where it's plain stupidity to continue to dump that kind of money into the minuscule gains like that. If you've gotten to the point where you've offloaded something like $2k in these types of "upgrades" (and gotten a whopping 14hp out of it), then I suggest you take a step back and look at what you're doing and really analyze it.

There's spending money to make your car faster, and then there's spending money because you're too dumb to know any better.

A fool and his money are soon parted. Just my $.02

 

Wow, there are some excellent replies here!

It's too bad there are no hard numbers available to validate use of the "Hype-S cams". I was considering installing them when I do my 105,000 maintenance - as I would already have a decent amount of the engine bay apart and would further guarantee reliability through use of factory parts. (Although I'm not sure if there are any special provisions needed to make these cams work in the 3.2's cylinder heads.) I mean, I would love to use Bisimoto's regrinds, but I have no plans to install a J&R ECU in my ownership of the car which, if I'm not mistaken, would be the only way to take advantage of Bisimoto's Stage 2 cams.

My philosophy is to incrementally improve the TL's "experience" without compromising reliability or drivability (i.e, luxury features). Of course I'm willing to make exceptions to messing around with luxury features (such as 62A motor mounts) but, at the end of the day, I just want to put the clutch in and turn the key without throwing a check engine light or having to change maps because it's a cold day. Because of my estranged philosophy, I believe this rules out running Stage 2 cams in my TL.

Of course, if anyone could chime in on their experience with Bisi's Stage 1 regrinds, that would be much appreciated. Maybe they might strike a balance between reasonable performance and reliability, or maybe that would just be splitting hairs at that point.

Thank you all for your responses and insight. As it seems this kind of information is fairly rare, in the future I will be sure to post what I end up going with and my experience in doing so.

 

I had the Type-S cams in my 05 accord coupe and they definitely did help out in the 3.0 compared to the stock cams. I dont have exact numbers, but they did feel a hell of a lot different from each other. Decent power difference was made from the upgrade.

 

I don't know who Komet is, but I'm going to go out on a limb and guess he likes this thread!

 

I guess " some one " will just have to do this.
I'll have this done and report back.

 

Well Said I Now feel like a Fool becuase i do not know what to buy first HFPC or Bishi Cams

 

What about the 3.7 cam?

 

^ this don't fit. unless your talking about MDX 09 camshaft.

 

^ I think I have read some of your post about the 09 MDX camshafts being plug and play plus it has a better lift, duration, and are even lighter than the Type-S cams, correct?

 

Supposedly the RL cams are the way to go.

 

Flashpro

 

Thanks. I'm going to into that.

 

RL cams are quite a bit more expensive than the TL-S cams. I think like $700 for front and rear camshafts.

 

Anyone know tl s and rl cam specs... also part numbers for both.

 

09 mdx 325 for both,

 

09 mdx fit ?
Lighter ?
Specs ?

 

they fit in my built tls heads. . lighter. i measured both tls and mdx same profile but i dont have a degree wheel so yeah...

 

Best cams that fit a 3.2?

 

how muchndo you have. i can recommend billet camshafts

 

Specs are in this thread:

2007/2008 TL/TL-S



2005-2008 RL

 

Why are RL cams so much better? Correct me if I'm wrong, but isn't the 05-08 RL rated at same torque and only 4hp more than a type s?

 

^ power band is much fatter. It pulled from low to high. while the TL-S cams only shine when vtec is engaged

 

^because the RL is the superior car, it has the superior engine. i forgot all the little details, Family guy, but you can find the little differences by checking out Roberts thread. Yungone has taken apart many J-series engines and he knows them inside out. he list the differences in his thread, STATING that the RL has the superior parts. but more expensive obviously, thus why we compromise and take the TL-S cams
