I have been running the 09 IM on my 01 CLS for over a month there are large gains throughout the powerband.

Yeah well Ill consider this tried and tested. Air fuel ratio was ok so I wasnt running out of fuel. Just doggy off the line. Couldnt get the tires loose WITH the bottle when normally the tires tear off without the bottle! Good news is I saved you all lots of money!!

Craig... Maybe its the throttle body size that's causing the loss in tq... Regardless try out that mdx spacer that's guaranteed...
Oh by the way I uploaded that pic you sent me looked good

I didnt leave it off. Would have thrown a light. I wrapped it up to keep it isolated from the engine temps and left it plugged in. I cant imagine the little diff in the temp readings would of made that much of a diff to the power. I mean this car SUCKED. It pulled ok up top but from a dead stop it had no torque. I just think it was TOO much air. If the engine cant pull it in...its counterproductive.

how much gains do you guys actually expect from these things?
unless your running boost....dont expect anything with these changes...and in some cases, you can expect loss of power...and a big waste of money
there's a reason why the TB is bigger on the 09...but that wouldn't make the same difference for your 3.2 or 3.5....
obviously 09 model is a bigger motor in terms of Litters... and just making a bigger motor doesn't make power, unless you let it breath efficiently and add the needed fuel (yes yes i know, captain obvious) ....a certain motor will only suck so much air...all based on the bore and stroke.... just because your TB is now so much bigger...it wont help anything... you can install a 5 inch TB...and it wont make the kinda difference you expect.... think about the CAI and how much research the techs put into it (im talking about real companies, not some "backyard" company, bending a pipe, spraying it with some nice shiny chrome, and calling it a CAI).... all the sizing and bending, and size changing at different spots, the length, bends...all make a difference in the velocity....which is very important.... its not so hard for Honda to have just installed a much bigger TB on everyone of their cars.... but you dont benefit from that...in fact...too big of a TB will ruin the velocity of air inside your IM, causing power loss....the only way to take advantage of all this is...to keep going deeper....start port matching...runners, heads, bore out ur sleves, even go a longer stroke if you can... thats when youll take advantage of these "bigger intake components"...you will actually need them, if you started from the bottom...
and going bigger on ur IM.... just increased volume for air that wont be able to get sucked into...bcs again, it is sized based on the size of ur motor..... im talking about our cars here....especially Hondas....
dont look at american cars...u change an air filter on them and u get 30 whp... theyve got big motors with huge restrictions...in fact they're de-tuned by means of bolt ons... thats not the case with our cars...
now here comes forced induction.... and things change.... this is when you can take advantage of a bigger bore TB....larger IM, if possible ported, and port matched runners...and blah blah blah
in forced induction is where all this makes big differences... obvioulsy, the more air you force into ur motor...the more power you will make (assuming ur adding the needed fuel)
hope i didnt ruin anyone's motivation on this TB & IM issue... if nothing else...just let it be my opinion and dont let it get to you...
by no means do i wanna bash out on anyone... but 600-800 dollars on these things, is a hell of a lot of money for nothing....unless ur boosted!.......
for that money...id recommend, lighter crank pulley, IM heatshield, and a bigger aluminum radiator with a higher pressure cap! ull gain more from this...
and you wouldn't risk hurting performance for sure
again just opinions and thoughts..

The following is not opinion, conjecture nor wag, it is my experience:
I have:
P2R CAI,Thermal gaskets, 71mmTB TB coolant delete 09 3.7TL Intake Manifold & P2R adapter/spacer VSA delete DC Sport headers,RT Cat Magnaflow 2.5" exhaust UR Pulley set & Unichip.
My car has much more usable power from idle to redline. I don't care about HP numbers or dynos so I did not dyno teh car but can report that I went from 6.5 / 14.5 to 4.7 / 13.4.These are averages over numerous runs.
In real street driving my 01 CLS is transformed now it is pretty quick in addition to comfortable and reasonably economical (22/28) average MPG driven pretty hard.

That mustve pissed you off lol.... Sure man,,, I welcome opinions.
Just keep in mind that what I said is based on the expected gains vs. $800 lol ... Just like the ridiculous catback exhaust from comptech for $1200 for 7.5 whp gain. Which I'd never do if u put a gun to my head. I don't care if its stainless steel or gold for that matter.
Yea, you might bring up the question "how are you gonna gain any power, if u don't do these things"....simple, you do ur own exhaust at a good shop for half the price or less..u get the exclusiveness of having smth unique rather than what everyone else does..
At least its what I do and have done for longer than I care to remember

I agree 1200 exhaust & headers is outrageous, I got used DC Sports for 250 and with 80.00 per Magnaflow had a Corvette shop fab my catback to them for 250.00.
I did not pay 800.00 for the IM, I don't know where that number came from. I bought a 71MM TB with all sensors for 250.00 from P2R and got 50.00 back for my stock TB and got the 09 manifold & cover from my local dealer for 350.00
In all seriousness the IM really tied all of the other mods together it was the last thing I did and it made a huge difference.
The thread for the IM mod is here:

You did so much more that what these guys are talking about and I agree... But for me to just go and slap a bigger TB and expect what most ppl expect is also lying to myself...its just not that simple!!!

i have a question.
has any one tried only swapping the 09 throttle body on to a j35a8 intake.
the difference in the picture was HUGE.
i would like to know if it has been attempted. is it compatible with a tb spacer?
what is the compatibility ?

sorry opel but can we get this thread rolling again. i don't care about the cost but the hood clearance sounds good. will this mod hurt or help a ua7 with both 4g mani and tb? its been years since this thread first opened so prices have possibly gotten lower, if not theres definitely more 4g tls in yards now. i need more info!....... and more lab rats lol

Going down the rabbit hole of originally looking at bored out throttle bodies, it took me this direction and to this thread. Now, having read through this thread and seeing Opel's response, has anyone tried this setup on a supercharged ua6? I'd be interested in knowing if everything fits the same as the current stock manifold setup especially where the S/C bolts up to the throttle body.
