Congrats on the times, that's fkn awesome to hear of a 13 second CL.

Hah...there's soo many questions I have for the 3.5L's, the only thing I know is the fact that the motor is from an MDX.

Congrats again.

very nice..

congrats, thats a very very impressive time for an allmotor auto cl-s, your right up there with the s/c and n20 guys, are those all your mods in you sig

props once again

Chopsie

Wow, those are some great times Steve. Like the others, glad to see the hard work paying off.

I see you put the bitch on the slim fast plan

Ant7701

Nice times man...nice times. How do u like those tires when ur not at the track?? Noisy, wet-traction??

typeR

mods list current

Allmotor did you ever run with only the icebox installed and on sticky tires? I'm hoping for a 13.99999999999X this spring with my icebox & better driving with the dr's. Is that too hopeful?

BTW nce runs type-r, 13.3 is godamn flying for your mods.

mattg

you're not going 13.99 w/o headers

Joe5.0

We'll see, but I'm sure there would be alot of pissed off people if I did. lol

Highly doubt you can drop 3 tenths off an already impressive time. What was your 60' and how was your shifting?

Joe5.0

60' was a crappy 2.26, and i dont powershift but I "speed shift". I let off the gas, only because I dont want to risk hurting anything. I experimented with powershifting and it didnt help my times at all. I have springs/struts to put on, and I'm gonna experiment with some spring isolators if the susp mods dont eliminate the majority of wheelhop/weight transfer.

If I could get a 60' in the 2.1's and get close to 100mph, why wouldnt it be dang close to 13's? I want to try it at a real track also, because our local tracks are crap here in Michigan.

Again its just a goal, as long as it doesnt get any slower or lose power from the intake & I'll be relatively happy.

mrsteve

iTrader: (1)

With the same power you make now you'll need to drop about 1-2 full tenths off your 60' time to hit 13s. And Allmotor on slicks only ran a 2.0.

I'd love to see it, but I wouldn't bet the farm that it will happen.

Good luck!

Joe5.0

Well I just installed an icebox yesterday, that is where I am hoping to pick up a mph or two. I would hope that with the susp stuff it helps with my launches, but who knows.

mrsteve

iTrader: (1)

FYI I trapped at 101 MPH once and only ran 14.1 with a 2.19 60'

I ran 14.1 @ 100 many times with lower 60' times.

Joe5.0

Yeah, but yours is an auto. I have teh l33t 6 sp33d

j/k

I know it probably wont happen, but it doesnt hurt to set your goal a little high does it?

mrsteve

iTrader: (1)

Auto or 6 speed won't make a difference. whp is whp... and final drive ratio and weight is close enough not to make a difference.

Again, GOOD LUCK i'd love to see it!

ou sig

I was wondering what your 0-60mph times are now? I know those times dont really matter and the 1/4 mile run is a much better test at a cars real power, but it would be interesting to know just to compare to other cars.

anyone can chime in if they know - but preferably those with serious mods

Joe5.0

Steve I dont kno how of a diff it makes, but my dr's are ~ 1" shorter than stock, so that helps my gearing also. I figure since I have to shift into 4th anyways I might as well try to get into it sooner, as opposed to 50' before the traps, which is how it is with the stock tires.

And I agree that a auto & manual should be close if not identical if they both have the same whp. I'm again "hoping" for somewhere close to 230whp/210wtq, but again we'll see.

GAP!

very nice #....steve

nice!

The best I ran was a 14.10 @100.70 60t was 2.19 so were all running very close

chevyjase

Impressive times..congrats. Can't wait till the f-in snow melts here to test my CL-S 6sp at my neighborhood track, no mods yet but I like to test and tune gradually seeing what really works. I definately need drag radials and a CAI to start.

darrinb

whats next on your mod-list typeR, and did u get your unichip custom tuned??

typeR

good question

SCTL-SS

I am not surprised(impressed yes but not surprised) that you wanted to run me. That is just very impressive times. In the Na category that is almost untouchable!! Once again congratulations and thanks for raising the bar.... by lowering the ET
Maybe down the road we can meet up at the track. Hows that sound??

sp3shul

sorry...i know everybody is going to throw their popcorn at me but i am still new to the cl....can somebody explain the 3.5L concept to me...is it a 3.2 witha stroker kit...is it a "ls/vtec" type of mod...i saw somebody say something about a MDX bottom end. a little help please???

mrsteve

iTrader: (1)

MDX/Pilot/Odessey -> Crank, rods, and hardware (bearings, etc) Custom pistons to lower CR.

You don't have to use the actual block, the crank and rods will fit in both the J35 and the J32

typeR

best bet now is the RL short block as is or just the internals

mrsteve

iTrader: (1)

That'll bolt up with clyinders and everything?

Hmmm

Allout

I think there have been other discussions that the RL motor is different than our design. Don't think it'll work. Probably have to take the whole motor to work.

typeR

old RL was different thats what youre refering to...even if you dont know it...the NEW RL is a J series and all the parts WILL bolt right in

02AV6

Congrats TypeR Indeed great time for NA.

As far as new J-series RL block, it needs to be determined if there is enough piston clearance when installing CLS heads on it.

Ken1997TL posted this info on the 2005 RL motor in this thread:
http://www.acura-cl.com/forums/showt...hlight=2005+RL

Regarding the 2005 RL's engine compared to the MDX, this is what Honda officially has to say:

The 60-degree aluminum-alloy 3.5-liter V-6 of the RL features architecture that's related to that of the powerplant in the 2004 MDX. Few parts are shared between the two engines, however; comprehensive changes give the RL powerplant an entirely different character than that of the MDX.

The forged crankshaft of the RL is similar to that of the MDX, but with revised counterweights to accommodate the weight of higher compression pistons. With their taller, reinforced crowns, these new pistons raise the compression ratio (relative to the MDX) from 10.0:1 to 11.0:1. The previous generation 3.5 RL had a compression ratio of 9.6:1. The elevated compression ratio is a key element in the horsepower gain compared to the previous generation engine. Part of the reason this elevated compression ratio is possible is an oil jet system that sprays cooling oil on the underside of the piston crowns to keep temperatures in check. New steel connecting rods are forged in one piece and then the crankshaft ends are broken , creating a lighter and stronger rod with a perfectly fitted bearing cap.

Like the MDX and the TL, the RL uses cast alloy single overhead camshaft cylinder heads that incorporate tuned exhaust manifolds as an integral part of the casting. Made of pressure-cast, low-porosity aluminum, these lightweight components improve overall packaging, enhance exhaust flow and allow the optimal positioning of a primary close-coupled catalytic converter on each cylinder bank. To ensure positive sealing, the RL has a three-layer type head gasket like that of the MDX, TL and NSX. A single Aramid-fiber reinforced belt drives the overhead camshafts. The RL cylinder heads have 36mm diameter intake valves and 30mm diameter exhaust valves. As a point of reference, the MDX has 35mm intake and 30mm exhaust valves.

Acura VTEC(TM) (Variable Timing and Lift Electronic Control) is a new addition to the RL, and is a major contributor to the engine's large gains in horsepower and torque. The system operates the 12 intake valves in two distinct modes, so that the operation of the intake valves changes to optimize both volumetric efficiency and combustion of the fuel-air mixture. At low engine speeds, the intake valves have low lift and are open a comparatively short period of time during cylinder filling. At high engine speeds where breathing is critical, the valves switch to high-lift, long duration mode to deliver the best volumetric efficiency. The VTEC(TM) changeover point is undetectable to the driver and occurs at 4950 rpm.

The RL uses a 3-rocker VTEC(TM) system similar to that of the MDX and TL. This configuration allows each of a given cylinder's intake valves to be controlled by its own low-speed cam lobe, allowing for staggered valve opening and lift. (By comparison, with 2-rocker VTEC, a single low-speed cam lobe controls both intake valves for each cylinder).

Better mixing in the cylinders improves both combustion speed and combustion stability. When the engine reaches 4950 rpm, the powertrain control module (PCM) triggers the opening of an electric spool valve that routes pressurized oil to small pistons in the intake valve rocker arms. These pistons slide into position to lock together the three intake rockers in a given cylinder, which then follow a single high-lift, long-duration cam lobe. The intake and exhaust valve timing and duration is unique to the RL.

The 2005 RL uses a new dual-stage intake manifold that is designed to deliver maximum airflow, and accounts for 15 percent of the horsepower (out of 75 horsepower total) gained over the previous-generation 3.5 RL. The 2-piece cast-aluminum manifold is also very light. Compared to the one-piece, dual-stage unit used on the MDX, the RL manifold saves 2.6 lb.

If this information is accurate, more information is needed to know if the Crank and Rods are interchangeable. Block and Pistons do not sound interchangeable to me.

typeR

im not sure what you're hearing but i assure you the block and pistons as well as 99.9% of it will swap,for anyone that would want to do a 3.5 i would recomend the crank rods and pistons from the RL

mrsteve

iTrader: (1)

Would the pistons still keep the 11.0:1 compression that they do in the RL? That's the problem, seems like compressiong might get kinda high.

What's the CR of your motor?

Allout

The 2005 RL short block lists for $5,524.74 and the short block for my 2003 CL-S6 lists for $1,587.97. MDX short block lists for $1,613.17. Not sure what the difference is in the motors but 3.5 times the cost must mean something.

typeR

back on the subject...at 106 with upper/lower intake and throttle body,headers wrap possibly hi flow cat and b pipe,and a limited slip i really see the possibility for a 12 second pass on the motor

mrsteve

iTrader: (1)

Hmmm... do you really think all that is gonna add 35-45whp? That's what you are gonna need to run 12s
