mr.almeida

Hey guys, I've been constantly debating in my head what would it take to get our cars into the 12's in a 1/4 mile, N/A. I have a 3rd Gen Type S so I'm thinking I'm already in the high 13's, 13.9 at least. Here's what I know I can do so far.

-Pro Cats
-Custom Exhaust (2.5" or 3" piping?)
-CAI
-Thermoblock Spacers
-Comptech Short Shifter

If there's anything else that you would suggest please add on. Now with all these mods I don't think I'll be able to break that barrier. I know it would probably take a lot of weight reduction to do so, but that's too extreme. Perhaps if Hondata ever gives us something to play with then it'd be more realistic.

Give me your thoughts and opinions about hitting a 12.9 N/A.

subinf

I'd stay away from 3" piping

ACCURATEin

I'm sure it's possible. But. You will need to shave about 800lbs off the car.

lookinco

lightweight wheels and good tires. UR lightweight pulley. CF hood.

mr.almeida

Lightweight wheels I have, 17" Volk TE37s, not really a fan of pulleys, CF Hood I wouldn't mind if I could find one.

BustedJack

Lose weight on the car, put the charger and other goodies.......... you'd hit 13.1 but high 12s very tough to do

lookinco

He wants N/A, so i guess no charger for him. I guess all you can really do is weight reduction.

ACCURATEin

And be sure not to run the car down the track on a hot and humid 85 degree day... as i learned the hard way. haha.

lifetimeofwar

Why are you not a fun of pulleys if you dont mind me asking?

Also to brake into the 12s N/A is going to be one hefty job. Good Luck.

I havent really ever seen a set of pullies do much myself, but this may be due to the fact that ive always modified turbocharged cars. Im now used to the supras, last cars were diesel trucks, a WRX, a twin turbo stealth, an fc rx7... I suppose with the ease of power production when it comes to those cars, considering the factory boost, the pully gain seems negligible.

I would however, go with the 3", you wont need it by a longshot, however, if all you like doing is drag racing, and a number is what you are after, then i would do it based on the fact that you need not worry about low end power production if drag racing's the thing. Any bigger however, and you may have problems, 3" at some rpm may do the same. With the larger piping, you may get some exhaust gas reversion. I would assume that a FWD 3500 ish pound car without a driver would need mid 300's to make 12's a regular thing. Most heavier cars, i.e. supra, 03-04 terminator cobra, SN95 mustangs, even the GS/SC300 are roughly that weight... Without gearing assistance being the issue, for instance gearing an SN mustang to run the traps on the rev limiter, most of those cars need at least 330ish wheel hp to do the 12's thing consistently with an average joe driving. Ill give the nod to the RWD crowd, as it is easier to get traction with them. The one thing i would be concerned with in the TL is gearing. Im not sure how good the new S is as far as 6mt, but i have an 05 and i havent spent too much time drag racing it. I would concentrate on the wheel/tire combo, and try to effectively alter the gearing to your benefit by playing with wheel, and of course, the all important tire height! Without an abundance of power, getting there will be tougher based on the overall difficulty of making the kind of power necessary based on the weight of the cars, especially with what ive found is a limited modification market!

Ill have to check back here, i would love to see a TL in the 12's to be honest! If you are in florida i can get you some 5x4.5 bolt pattern wheels that are enormous to strap to that thing if you would like!

Hope something ive said here is of use!

Take care

kyle-wdp

slicks, high rpm launch and about 300+ to the wheels.....good luck, id love to see it done but I dont think its possible in street trim.

ndabunka

Do the NSX's even run 12's? If not, then I don't think it matter HOW much weight you remove, it won't be enough.

JOES05tl

it aint gonna happen. Not saying its not possible, but you wont break 12's

Yeah, 12's are very unlikely. Good luck though.

againstallodds1

The best I got in my TL was 13.12 at 108 mph. That was with a blower and 50 shot of N2O, with BF goodrich drag radials. The key is in the 60'. You will have to cut at least a 2.09 to do it. That was my best 60' in this car

Black_05_TL_6SP

Stock, the NSX-R(Japan) runs 13.2 and the US NSX runs 13.6 Stock. Modified, I think it would make it into the 12's. The TL is going to need to be boosted to make up for the weight. Without striping it down to shell, it would be difficult to get into the 12's N/A.

With the limited parts right now for the TL, its hard to do much more then what has already been done.

It will help once the Clutch and lightened flywheel have been released, it will use all the power being produced and free up some that is already there from the flywheel.

If you are looking for every bit of power N/A, the Pulley is going to be needed.
If you are really serious about it, you will need to take the motor down and lighten the crank, rods and pistons even more then they already are.

Good luck, Jason

manual transmission

3.5L or 3.7L stroker

full intake, bored throttle body (can it be done on drive by wire?), ported/polished intake manifolds, thermoblok spacers, pulley, full exhaust, i recommend heat treating as many of the intake/exhaust parts as possible

cf hood, 15LB or less 17" wheels, sticky street tires, 2 piece rotors/brake kit

minor weight reduction (trunk linings and misc linings from engine bay), low tank of gas

i think the above would be entirely street legal and with a good driver catch a high 12

csmeance

Also getting rid of those 9LB boat anchors on the front and trunck of the car may help with the weight reduction.

Bender75

3" piping sounds way to big you'll probably get lag. I had 3" on a v8 that I owned and it was perfect. 2.5 sounds good for 6.

OMP Prelude

good luck on hitting 12s , you might just do it to prove some of us wrong, and do u really know who has the fastest n/a TL right now cause i want to hit 12s too n/a before i install the charger

chirik

No possible without HUGE weight reduction, skills, drivetrain and power.

I'm sure some of you have heard of 02AV6 with CL-S engine who post on CL and Accord forums, shared TONS of knowledge, etc. but most important ran 12.8@109mph. He made 331whp/273wtq SAE Dynojet on his '02 Accord V6 and his car weigh only 3100lbs.

I'm sure with smaller pulley and tuning supercharged TL peeps can reach his power but TL weight is what killing it and you must have track driving skills .

lookinco

Too bad he doesn't what the supercharger at all, so it would be even harder to reach his goal. It would be lucky if I can hit the 12s.

pohljm

I think the only way you will get there with a N/A TL would be to start timing it a full second into your run!

typeR

i think it's very doable...i hadnt touched the heads was on stock exhaust..street tires. the 150 lb each stock seats one wheel drive and i was knocking on the door.

topckret

Hey guys, I don't want to impede on the thread, but can you guys please just go on this thread and just add your names to the petition even if you guys already have exhausts, whether comptech or not, whether you want an exhaust or not, i need names (bodies) to sign up on the petition so we can get GReddy to manufacture us a catback...Thank you for your cooperation.

Didnt you have a crank in the car? If the displacement was larger, that should have helped a good bit!


By the way, 3" exhaust will not add "lag" to an N/A motor. The "lag" doesnt really even happen when you use oversized exhaust on a turbo car. It will lack some of the percieved low end torque, however, in most cases, the larger the easier it is to make power!

If its possible, i would like to see it, but ill still stick to the mid 300 whp range to get it done!

take care

EndofFile

I dont think its possible n/a without some serious engine work. Simple bolt ons won't push you into the 12s. I used to have a 350z and those guys struggle and continue to struggle to run 12s n/a. The TL is a bad platform for drag racing. Its FWD, 4 doors, and the engine outputs relatively low torque. If you want to hit 12s n/a, I suggest you get something with a V8.

Eoanou

With the TLs current market it's impossible if you don't do some form of weight reduction, well unless you use a 150shot of nitrous.

Hypothetically speaking what you could do to make it a 12sec car without weight reduction:
Race Cams
Ported Heads
Increase bore and stroke of the motor to a 3.7L
Improved lighterweight Flywheel
Improved lighterweight Clutch
Lightweight Wheels (Less than 17lbs)
Smaller Battery (One for sale is only 11lbs5ounces)
Cam gears
Vtec Controller
Run an open throttle body
Port the Throttle body
Improve the transmission
Improve the gear ratios
Raise the revs to around 9,000rpm
Drag Radials
Manufactuer a lightweight block
Manufactuer lighterweight internals (Pistons, valve train, crankshaft, connecting rods, etc.)
Bigger Fuel Injectors
Advanced Tuning
Smaller gas tank
Better bigger fuel pump
Better spark plugs (denso iridium)
Better spark plug wires
Run open heads

Maybe some more stuff, but essentially you will need to rework the motor, that should actually give you maybe 400hp, I'm not sure, but most likely it will, Mugen created the Acura Legend MAX. Essentially it's a project race car, that uses the RL body and probably the J-series motor, and I think it has around 400hp and probably has the same mods.

Eoanou

Also forgot to add a bigger radiator made out of aluminum and radiator hoses.

JOES05tl

make it a 12sec car without weight reduction:


- lightweight wheels?

- a lighter battery?

- lightweight block?

Black_05_TL_6SP

For the most part I agree, but the plug wires? The TL does not have Plug wires. It is a direct coil system. There is a coil mounted to each plug.

The only problem with undertaking a project of this nature, would be the cost involved. The TL was not meant to be a race car, and with the things done above, it would no longer be a reliable driver. It would be better to just go buy a 240 and drop in a RB25. Cost wise you would come out better, it would be turbo, and you could get it into the twelve’s without a problem.

The next problem is the tuning, as of this point, no one has been able to get a reliable ECU system to work with the car. Do the standard bolt-ons for the car, and be happy with what you are able to achieve at this point.

Give it some time, as the cost of this car goes down, and there are more parts and tuning options available, then you should be able to achieve the 12's. None the less, weight reduction is going to be the first major key to creating a 12 second TL.

Eoanou

Oh really, I didn't know the TL was a direct coil system, but anyway you're right that the car would lose it's drivability, but it'll still be luxurious!

dmb4325

You talk about a lightweight flywheel and clutch, but I dont think they exist for the 3G TL, but if you know of something that works, let me know...as far as getting the TL in the 12s would be unbelievable, but not probable. Honestly, I hope you prove all of us wrong cause that car would be badass...goodluck

fant0m_TL

take a huge 10 foot tall rubber band tied to two posts, throw throw you car in reverse (into the rubber band), then slam down the clutch... then you'll really "fly"
