I'm dropping my car off on wednesday at Injen to haev them R&D their Cold Air Intake system...

They'll have my car for 3 days.. and stated that they will dyno the car before and after 3 times.... I cant wait to see the results.. Hopefully its something similar to the G35 Coupe intake they did that brought the motor alive...

Ill let you guys know how it goes..

Sorry, what's that?

jimthegreek

Cold Air Intake system..... Draws cold air from the lower front of teh vehicle and forces into the throttle body directly....

Its basicaly a whole new intake system for your vehicle.. Generally adds anywhere from 4-15hp on a vehicle depending on how restrictive the intake system on that vehicle is...

copter

Doesn't the TL have kinda a CAI???

rets

Thanks. jimthegreek.


To copter, I guess jimthegreek probably tries to get better performance from the newer system. TL has the similar system, but maybe it's not so efficient to match ppl's needs, and his new system could have better way to squeeze more HP by properly cooling and compressing the air.

Acura says,

COLD-AIR INDUCTION SYSTEM

Cool air is denser than hot air and allows an engine to make more power by packing more oxygen per given volume. To capitalize on this fact, the TL has a special cold-air induction system as standard equipment. Ambient air is picked up through an inlet in the left front fascia, and fed by a duct to the engine air intake. Depending on vehicle speed, this system supplies the engine with ambient air that is much as 15 degrees F. cooler than typical engine compartment air.

A new low-restriction induction system improves breathing in the new TL. In addition to providing more aggressive sound under acceleration, this new system flows 40 percent more air than the system in the '03 TL, and about four percent more than in the '03 Type-S.

jimthegreek

the new TL does not have a "TRUE" cold air intake. Its not attached from the front induction to the actual intake inlet.. So its not really forcing air into the intake system....

Putting colder air into the intake and throttle body improves HP and gas mileage, depending on how you drive it. Injen is shooting for about 12hp gain through the intake..

I'd like to see what they get out of it... anything over 5hp would be nice...

jimthegreek

The A-Spec Concept uses a similar intake with a more free flow exhaust system...

rets

Thanks. Please keep us update.

I think the same way. Your performance upgrade should be more efficient to make those cold air into the engine. With the proper ratio of cold air and gas, you could generate more HP for sure.

Good luck, let us know what happens.

Oh yea, could you post some pics of you ride. You have the color combo I'm looking to get in the 05. I also plan to lower with 19's as soon as I leave the dealer. I would love to see what it would look like.

jimthegreek

i posted pics of my car already somewhere...

Thats with the 18's on it

JPTLS03

Wow, that thing is sweet!

Cool I hope the gains are worth it. A true Cai on my 01 CLS mad a world of difference. I really need one for this car. I keep hitting the rev limiter cause I dont know the engine well enuff yet to be able to tell when to shift by engine tone.

jimthegreek

Initial dyno run this evening before i left showed 13hp.... their pushing for over 15hp... gonna re-do the bends and see if they can make it up...

im very happy with it so far...

Thats great news. Any Idea about how long before its released to the public?

jimthegreek

They are completing the final product today.... Running the final dyno tests and i get to pick the vehicle up. They want me to drive the car around for about 2-3 weeks to make sure i dont have any issues like check engine light, stalling or anything else. At that time, they want me to return the vehicle for a couple hours, do one more dyno, make sure the vehicle is still performing the same with the CAI, and from there, the intake goes to production and should be seen on the market in 2 weeks.. He told me that the intake should be available sometime around February 15, and a SRP of 249.99.. So i would say you'll be able to pick it up for about 210-220 from a vendor...

I'll take pics later today of the intake system and post up a copy of the dyno sheet..

Great news Jim

gordon_gekko

wow. that sounds pretty good. i'd definitely be interested in one down the road if it's worth it.

JPTLS03

So it dynoed with 15hp gains? 285hp?

Lore

Jim:

Do you get to keep the final product?

n3985

CAIs don't "make" more horsepower....they more just free up power that was restricted.

VTEC=happiness

Is there a noise increase with the CAI?? I definately wanna boost power a bit, but not at the cost of louder car

jimthegreek

So far, the vehicle tested at 13hp more... but the way it was setup wouldnt be C.A.R.B legal yet, they are revising the final product today, re-dynoing it and then i get to pick up the vehicle....

Yes, i do get to keep a final product for myself for free... They do that for letting them use your vehicle.. Taking teh car back at the end of the month for R&D for a full cat-back exhaust system as well.

The CAI only makes the motor a little louder, but thats only at over 5,000 RPM's, the motor starts screaming once VTECH kicks in..... other than that, you really cant notice a difference except the slight whistling noise that is normal with CAI....

Product should be available to the public around mid- feburary.

jimthegreek

Thats what their aiming for...

Lore

How do we get involved with having companies perform R&D on our cars? It's like beta-testing... fun!

jimthegreek

Just got to know people or make contacts......

There's really nothing else out there to R&D at the moment.. normally they go after sponsered vehicles(show cars) as they can use them to show off at shows.....

brahtw8

Not likely.

Assuming it gives a 15hp gain, which seems like a lot for an intake on a car with an already aggressive set up . . .

The 15 hp. gain probably does not occur when the car is making peak hp. of 270, but rather when it is making less horsepower, so you get 235 instead of 220 at 5500 RPM (just an example).

jimthegreek

Incorrect.

At the crank, the motor is pulling 281hp as of this morning.

brahtw8

If you were addressing me, 281-270 = 11. So, if it does give a 15 hp gain, it must be at a point different than peak horsepower, which is all I am trying to say.

jimthegreek

not all motors push at exactly 270hp.. mine peaks around 267-268

need4spd

Are they measuring wheel hp, then calculating crank? Or measuring crank hp (I would be surprised).

Also, when are you going to post photos with the volks, I have not seen any yet, your others are the ziggens - thanks!

jimthegreek

I havent put the volks on it yet, and i dont plan on rollin on those tires during these months and im traveling alot between LA and vegas so i want the better ride of the 18's

jimthegreek

i dont want to keep throwing these numbers out until i actually get the Dyno sheet in front of me.....

I keep getting these numbers by email or by phone... so once i pick it up tonight, ill just scan in the dyno sheet and you guys can see for yourselfs..

LVSBB6

Impressive gaines.

How loud is the Injen CAI compared with stock airbox?

jimthegreek

Noticable difference at WOT.... otherwise, its pretty mellow but always available with an extra1 or so stomp on the gas...

GoBig

It would be nice to also see the air/fuel ratio in the runs as well. This well help to see if the car runs lean with additional airflow.

Hope to see pics soon. Brahyw8 is correct in saying the max gains would not be at peak. The intake probably frees up some low to mid range power. Jimthegreek, you are one lucky sob for getting into r&d with Injen, good luck with the exhaust system. I dont think they will be able to make too much power with that and keep it carb legal. As far as I understand if the upgrade makes teh vehicle loose its ULEV status it wont be carb legal. Someone please correct me if I am wrong.

jimthegreek

If i cant get a substational gain of HP out of the exhaust, i dont care if its legal or not. As long as its not loud and obnoxious, ill be finw with it... i dont have to smog this car for 5 years anyways...
