OK so did a couple of rolliing starts against my friends stock '08 IS350.

I have to admit we were at about 20-25mph in first. I had a passenger and he did not.

1st run - he gave me the jump and boy was it, I jumped out and left him about 1 to 1.5 car lengths to about 110. Then we backed off. He was not really pulling on me at all. I actually felt bad that I got such a jump, but again I was in 1st at about 4500.

2nd run - I gave him the go but when I kicked it, I went right past him about a fender and we seemed to be pretty even, BUT he was pulling slightly all the way up. We let off again at about 100-110 and he had me by about 1 car.

OK so here is what I noticed, his car was faster for sure the 2nd run, but I guess most cars are these days - we joked that he had to "wake up" his ECU.

Oh yeah, I had 89octane in the tank- but didn't notice any detonation. Both cars have 78k miles too.

Just thought I would share - I guess a J-pipe is in order. Decided on the XLR8 unit.

bigteninch

Oops, forgot - both cars are AUTO.

So a bone stock base 5AT TL, with a passenger and 89 octane, was only a car behind a driver only IS350 at 110, after you gave him the jump?

You should probably dust off your flame suit because you're going to need it.

bigteninch

Hey man, I was surprised for sure. I was just posting up to see what others were experiencing, not to brag about it. He beat me so that is that, just not as bad as I expected.

I also held the car in first manually so when he "jumped" I quickly came around him by about a fender, just as my original post indicated. So on both runs he was coming from behind. And yes at 110 I was 1 car behind. My passenger was my wife at 115lbs. So I hope that makes more sense now.

The guy I was running was a friend of mine so we plan to make it a frequent event.

Thanks for your post though - just a reminder of why I don't miss forums, everyone is an expert and all knowing - pretty cool I guess.

On paper, you would lose, but real world racing... Anything could happen.
Maybe you have a factory freak machine. Just get one more run in with vid and head start jump. You'll be good till 90mph

Sonnick

5AT TL traps 95. IS350 on a bad day goes 100-101. Maybe he filled up on diesel by mistake?

bigteninch

Ha, yeah maybe this things just runs good. I have had other cars some ran strong, some got spanked. That is really why I posted 'cause I was surprised.

I will get a vid next time - didn't even think about it at the time. My friend lives out in the country so each time we head over for a cookout, we'll make it a tradition.

I do think I will sneak a J-pipe on and see what happens.

He could have filled up on diesel though for sure - Honestly, maybe his is just a slow one, who knows. I have a Performance Box so we can time 0-100 independently and compare.

yeah but the races were from a roll. Totally different story at that point IMO. From a 20-25 roll I think 1 car length at just over 100 mph would be realistic. Remember how much more the IS would pull from a dig because it's RWD, that really helps propel its 0-60 time to 5.1 (numbers courtesy of C&D, anyway).

I bet if they raced from a dig, the IS would just roflstomp the auto TL-S into the ground.

Sonnick

I'm talking strictly trap speeds, which is a good indicator of how a car will perform from a roll. Not saying it didn't happen, but it was a fluke. IS350s are much faster than a stock 5AT TL. I would've expected the IS to pull over a car length from 100-110 honestly.

anx1300c

iTrader: (2)

Hardly. This is a Base TL too, not a Type-S. Take a 95mph car vs a 102-103mph car (roughly median trap speeds) and then add another 1mph or so for the passenger. A 9 mph difference over the course of 25-110 is ugly, assuming both cars have traction.

Anything can happen though.

tommy020

Your stock auto TL is slow, your car is over a second slower on 1/4 mile than this Lexus. keep dreaming

AtlM5

Yea I'm not saying it didnt happen because Im sure it did but when I race my friends 350 he ususally pulls a bit. Its not too bad but hes definitely a good bit faster and I'm modded.

Sonnick

This x100. Let's even say it was 6mph. That's still ugly.

mazdaspeed3God

^ Yeah flame suit is in order.


OP, I am pretty sure you raced the IS250 not the IS350. They look identical except for the badge on back. I myself can't tell if it's IS250 or 350 until I get real close to the rear end of the car.

TL 5AT on a bad day can get you 0-60 in almost 7 sec. IS250 can get down to 7 sec also. IIRC, the quarter mile times are fairly close to each other. So your outcome is about right with the IS250. If it really was the IS350, he was just driving, not racing. Or playing with you.

dgsedan06

IS350s arent slow. I raced one with only an intake and managed 2.5 cars to ~100mph. And he had his gf in the passenger seat! Is your TL a 6MT?

easy, look at the brakes, thats what i do. the caliper/rotor size difference is really obvious.

Hotwired05

I hate to wake up an old thread, but I saw this and couldn't resist. I ran a few stock IS350's and we were usually neck and neck, depending on my start and how I control the wheel spin. Now on a few occasions I was able to get half a car ahead, that's on a type S with a 6 speed. I'm not saying this couldn't have happened, but I have my doubts that it was an IS350, the reason I'm saying is my personal experience and if that's now enough, check out this vid:

YUNG.MONEY

It definitely is NOT an IS250
i ran a 2011 is250 F SPORT with my base 5at STOCK and STILL destroyed it
ran from a dig and had 5-6 car lengths before i shut it down at 100mph.
Maybe the OP made a mistake and it was an ES350? because i cant see how a 5at TL stock can hang with an is350. i ran an is350 as well and it was ugly.

YUNG.MONEY

the ES350's performance is quite similar to a base TL 5at STOCK just saying

Hotwired05

Ok I can see where someone can make a mistake between an IS250 and an IS350 but ES350?? I think you just called OP an idiot lol
Its a completely different body style, based on a euro Camry in essence, and mostly grandmas and grandpas drive it in the States. No offense, but if someone mixes those two up they shouldn't be allowed next to a car

YUNG.MONEY

Hahah i'm not trying to call anybody an idiot lol. Most people that post here are car enthusiasts and know cars pretty well but you'd be surprised how many people don't know a thing about cars. I'm just simply trying to make sense of this situation there's just no way a base 5at TL stock can pull an is350 especially with a passenger unless the driver is brain dead or there's something seriously wrong with the is350. It's as bad as saying that a stock is250 can pull a TL.

Donnell Turpin

SoundS a Lil sketchy to me

F23A4

I MOST cases, the smart money is on the IS350 vs a base TL with really on a 6MT (04-06 base or TL-S) being able to run.

With regard to the ES350 (as well as the Camry V6), its 2GR-FE coupled with that 6AT has enough pull to edge a base TL.

BEAR-AvHistory

You guys are forgetting both cars have over 78K miles. A lot of things can happen along the way. Something as simple as spark plug condition can make a big difference.

Is the 350 faster then the TL under as tested new conditions, yes. X years, miles & service updates down the road anything can happen.

anx1300c

iTrader: (2)

I don't know. In today's world of 100k + tune-ups and platinum plugs, I wouldn't put too much stock in that. I changed my plugs at 75k this past spring just because I'm anal, and they looked great. No difference in mileage/performance.

mazdaspeed3God

^ Yeah, the spark plugs these days last 100k miles easy.

Both cars in good condition the IS350 will smoke the TL 5AT, at any speeds.

Camry V6 is about as fast as base TL 6MT. Both base TL 6MT and V6 Camry will smoke the automatic TL.....

To the YOUNG MONEY guy.... The IS250 performs very close to the automatic TL.... both 0-60's and quarter mile. You can't go by the amount of hp only, the IS250 is a 6 speed transmission. It makes a lot of sense with the result here as the TL had a passenger, no passenger in the IS250. It's IS250 not 350...

Sonnick

^ I think the OP knows what car his friend has. With that said, the results are far from normal.

The 5AT TL would beat the IS250 from a roll. 0-60 and 1/4 mile is similar because the 250 is AWD. The TL has a solid 4-5mph trap speed advantage. I ran a modded IS250 in my car like 6 months ago and put about 63 cars on him from 45-110. I wouldn't do that to a 5AT TL.

mazdaspeed3God

Some people claim "friends" but they are just some stranger they don't really know... You have to keep in mind, that IS250 and 350 look so similar...


IS250 is available in both RWD and AWD trims. And the RWD is faster from roll... Looking at dragtimes the stock RWD is good up to around 90 mph trap. I know the stock automatic TL is around... 93 mph. But yeah, the TL is still a bit faster.

But things will change from 111 mph.


If you put 63 cars on an IS250 either the guy was just cruising (not accelerating) or just driving.

Besides, your car is a 6MT and is pretty fast for a V6 accord with all that mods you have on it. Your car is about as fast as a stock 2nd gen MS3 from roll.

Vroom vroom.......

YUNG.MONEY

I wasn't going by hp i'm basing it on real experience, i've ran a 2011 is250 fsport from a dig and pulled 5-6 cars by the time i shut down at about 100mph. Not what i consider a close race at all..even with a passenger there's no way that the is250 could pull

anx1300c

This might be your most sensible post ever.

And Sonnick was sarcastically exaggerating on the 63 car thing. You just need to tune up your sarcasm meter a little bit.

Sonnick

You know my car is faster than any stock MS3 lulz. Don't be silly, I've already raced a modded one with lightweight wheels.

Didn't know the IS250 also came in RWD. Not sure which one I raced, but it was ugly.

Always look at the front brakes!
the 350 will have a nonflashy bbk.
while the 250 has a ugly skinny 1 piston caliper.

mazdaspeed3God

You might have beat the driver by beating by 5CL... Gotta keep in mind that the IS350 is a night and day difference from the 250. It's not just the 100 hp difference. And I wasn't saying the 250 will pull on you... well, except for maybe roll racing from 100 mph.

lulz?
That was a lightly modded gen1 MS3. I also clearly told you that the gen 2 MS3 is faster from high speed roll. Your modded Accord should be about as fast as bone stock gen2 MS3 with two good drivers. lolz? lol..

Depends on the race application. IS250 comes in manual too, you didn't know that either din't ya.

Cute kid, not everybody on the street knows the difference.

you're not making sense.

People won't be able to tell if it's 250 or 350 until they look at the badge on the back. By looking at wheels I can't even tell if it's 250 or 350.... unless you park 250 and 350 next to each other.... If you just spot a 2IS you won't be able to tell it's 250 or 350. Catchin on now?
