I've been long wondering if the RL is quicker than the tests the auto magazines post. My first test was when I just bought it against my own 06 TL with less than 30,000 on the TL and about 5,000 on the RL.

RL won hands down in the hands of my brother and there was nothing the AT TL could do about it.

After adding a short ram, UR underdrive pulley and lighter wheels I decided to test my luck on an 07 TL-S auto.

2 passengers each car, I've had at least 50 extra lb in the trunk (don't ask) and 50lb of extra weight over the passengers in the TL.

It all seems like nitpicking considering the RL is about 500lb heavier alone.

Well...we decided not to go over 60 for lack of better test location. Both cars were in S mode off a traffic light.

If anyone can explain to me why the TL jumps off the line and the RL pauses...

 

here's a rolling shot.

You should get a slight jump from a start because you are awd. durin acceleration sh-awd is almost rwd so this vid surprised me a little.

 

the TL-S is lighter, has basically the same amount of power, and lacks AWD, so it has less drivetrain loss. it should beat you.. off the line, from a roll, etc etc etc...

only place the RL might outdo it is in the turns where you have AWD and he doesn't...

i test drove quite a few TL-S before I settled on an RL..and I always felt the TL-S felt quite a bit faster... but it also torque steered... felt far less luxurious...was much smaller... and cost the same...

RL = more luxury less sport
TL = less luxury more sport

but they are pretty close

 

I drove my friend's 2007 TL-S AT recently, which has the exact same engine as my year RL (2005).

The TL-S was noticeably faster and felt so from the driver seat too. If I didn't know better, I would never have thought they were the same engine. TL-S is not a small car, but the firm suspension of the Type S did make it feel quite sporty.

 

actually, quite the opposite, TL is the one to jump. Also, Sh-AWD is mostly forward biased as that is where most of the cars' weight is.

 

think I figured out why my car didn't jump immediately in the first video. That was the delay going from foot on brake to foot on gas.

The other guy was brake torquing the first couple of runs so I guess he was still using one foot to brake and one foot for gas on the last run.

Guess I gotta start using two feet for more immediate launches...I'm such a n00b at this.

btw, I've tried brake torquing the car without launching it and it goes up to 2,000rpm and no more.

 

don't really expect to beat a TL-S

 

Negative bro. SH-AWD can send as much as 70% power to the front or to the rear. As hard as the Type-S pulled on you, I wonder how you'd fair against a Non- type S?

 

ParaSurfer, you are correct, RL can send the power back if there was a loss of traction in the front.

I was talking about flooring it off the line. It sends most power to the front, and I have the little graphs to prove it

As far as a Non Type S, I have done this comparison over a year ago against my own 2006 AT. TL wasn't even close no matter how hard I tried (I drove the TL while my brother drove the RL).

 

+1.

 

from personal observation, besides being slow from the start (might be my own fault for not using both feet), the TL-S wasn't rapidly pulling away.

To me, they seem closer than one would think considering 3600lb and 286hp vs 4100lb and 300hp and awd drivetrain losses.

 

I traded in my '07 TLS for my '06 RL. I really liked the TLS but it sucked in the snow so I went w/ the AWD RL. I'm happy with my choice but the TLS got the RL beat on a straight away all day.

 

I will keep everyone posted as I unload the trunk and try this again with no passengers

I really think they should be close once I get the two pedal "race start" figured out, lol

 

You just contradicted yourself. Let me tell you how. When you floor a car what happens? The weight shifts aft causing added loss of traction to the front tires dont have the weight over them so the sh-awd shifts power to the rear. At normal speed and braking, the sh-awd is more fwd biased.

 

Why not both do it again using paddles or was that what you did? The shift pattern is different when manual shifting. Can you too do runs starting at 50mph? Wondering if the RL gains ground at the top-end.

 

I thought the RL's sh awd was mostly front wheel drive minus times the ecu detects loss of tration and then shifts power to the rear?

I thought it was on the mid too?

 

Yes, the MID shows me that most of the power goes forward when WOT.

We didin't have room to do any fancy acceleration beyond 0-60. I'll definitely try it out when I have room and a car to go against.

First video both cars were in S mode no paddles so I don't hit the rev limiter like I did in an unposted face palm video.

Paddles add for the driver factor which I wanted to eliminate and try to make it as equal as possible.

Then again...if he's using both feet and I'm shifting brake to gas...I lose time.

 

I liked the 0-60 Video. Pretty much what I expected. The TL-S is much lighter and puts more power to the ground. Even though the engines are the same with basically the same crank output the TL-S puts down more WHP and WTQ due to the less drivetrain loss. Hopefully you will post a 0-95 for a good 1/4 mile showdown!

 

This might have validity if done with controls, on a closed course or track.

Otherwise it only proves the shallow ego of an inconsiderate and irresponsible driver.

 

actually the RL is running a 3.7L engine and puts out 14hp more if not counting the mods which in theory should add 25 more.

 

you, sir, are a party pooper.

 

The RL will always loose against a TL-S in a straight line. It's pretty simple physics.

The TL is lighter than the RL and as well the 286 HP is divided between two wheels which allows for a 15-18% loss in power. The RL is heavier, outputs around 300 HP but has to divide the power into 4 wheels (all unequally) and as well has a 30-35% loss in power.

SH-AWD CAN send up to 70% of power to the rear of the car, and then out of that 70%, 80% to 1 wheel (MAX) during hard cornering. The SH-AWD system is configured to be FWD biased unless it is detecting serious slip such as in icy condition or sandy conditions.

 

small thing to note is that RL isn't stock and that so far the most gain the TL-S was making was off the line, after that it was gaining very slowly.

 

even with the mods I belive the RL is going to lose the TL-s off the line take it past the 0-60 and the rl might come out on top as it has great pull up top.

 

You are correct as far as crank HP is concerned but the TL-S loses less HP and TQ through the drivetrain due to its FWD setup vs your AWD setup. You have to look at WHP and not crank numbers.

Your mods help for sure but still not enough to keep up I believe. Love to see the races. Keep them coming!

 

haven't had a chance to put the car on an AWD dyno as those are kinda rare in the area.

Have no idea how much power it's putting down to the wheels, just know that it's a heavy beast.

 

Its not really a comparison to your RL but here is neuronbobs dyno of his 06 Acura RL 3.5L with I/E. I am actually very dissapointed as to how much drivetrain loss this car has with AWD. 201WHP and 176WTQ with I/E........ouch!

I think Bob only had the exhaust on his. not sure if we can compare directly but should be close enough in theory.

I know they updated the software for SH-AWD so I have no idea if they made it any more efficient.

 

Bob had a AEM CAI for the 3G TL 3.5, with a slight modification, and an a 5Zigen Fireball Mega designed for the KB-1, in addition to the A-Spec suspension and wheels.

 

guess the only thing I got that he didn't is the 10hp plus the pulley.

If that's 201hp with all those mods...that is pathetic.

 

Does anyone know why the RL makes 300hp and the TL-S only makes 286hp? Is it tuned differently or is something different inside the engine?

 

I thought it was pretty much established that you can't just toss SH-AWD onto a dyno. You have to unhook the rear drive shaft and dyno just the front wheels to get an accurate measurement of power.

 

In 2005, the Society of Automotive Engineers (SAE) changed the way HP was calculated. Most European and Japanese makes had to revise their figures downward.

The 2005 RL was measured under Honda's old method and got 300. The 2006 RL was measured under the SAE standard and got 290.

The TL-S was probably given 286 to make it seem lower than the RL for purposes of marketing. But the gap is not as big it may seem from 300 to 286.

 

RL is too heavy no brainer tl will win everytimeee

 

that is a good question. Ask neuronbob who had his RL dyno'd. im not quite sure. There are AWD dynos so I would assume that you should be able to dyno the RL on a AWD dyno.
