To follow up on FP's excellent advice, I'd like to see some dyno plots to know how much hp each of the mods are going to get me. I don't know about anyone else, but I don't like to spend money on mods that do not have dyno-verified gains. All of the things in this thread make sense, but how they translate into actual hp is up for debate IMO.

So if anyone has any before and after dynos of any of the mods listed in this thread, please post up.

 

Anthony,

What web site are these part numbers good? I have tried several sites and the part numbers didn't work. At least for the Induction part.

 

I'm going to hold off on this offer until I test some changes with my intake and exhaust and run a dyno again.

Will keep you posted.

 

FP,
When you mentioned "I'm not sure there is any performance gains by replacing the injectors."are you referring as a stand alone mod (only injectors) or injectors +ECU tune up (i.e: LET Motorsports)


Salu2.

 

nevermind, looked it up in the manual

 

Also, looking at $45 each for a reconditioned set, anyone know where to get a better deal?

 

I was just going through this thread again after not looking at it for some time and I noticed a few things.
The first would be the part number of the engine cover (air box), it calls for part#A112 090 15 01. I had this part and I found that it touches the hood liner and marks it. The correct part number is A112 090 11 01 which gives about 1/2" clearance. It should be noted that this engine cover is a two piece assembly and requires the front part to make it look correct. It works without the front part which is only a cosmetic addition. This front part fits V6 and V8 air boxes alike. The part number is A112 010 04 67.

When I fitted the MAF unit above I replaced the sensor in it with the one from the original MAF unit on the Crossfire, I wonder if that was the correct thing to do. I always thought that the sensor would be tuned to the MAF it was in.
What are your thoughts?

My later post on the Mercedes engine cover mods are in this thread.

Maybe nobody noticed......

1. This thread was dead 2 years ago.

2. TVT Design was banned over a year ago.

 

It got revived and I noticed that it had some bad info on it and decided that the correct info should be noted.
I am aware that the OP was banned and that it is an old thread as I have been here a while, but bad info that may be misused is best corrected.
Look upon it as a public service.

IMO, the MAF sensor is calibrated according to the tube size that it fits in. However, the ECU does quiet a bit of compensating. Like what was said above, at first, the engine is a bit slugish and bugs down. It settles after about 15 mins. How about you switch back to the MAF sensor that came with your 74mm tube and report back your findings. I'm curious about your results

You did the right thing. dont use the V8 sensor, just the housing.

 

Would it be a bad idea to get these used/ junkyard? What are we looking at as far as power gains and throwing dtc codes? And last question ive read that its a challenge to "relearn" to drive a manual after upgrading the throttle body. Same here?

 

I tried using the 76mm MAF with the V8 sensor, but did not have good results. I ended up using the 68 mm MAF sensor in the 76mm MAF body, runs great. I plan on going back later and retrying the bigger sensor. I have since thought I may have had a leak on the rubber gasket. will post when I get around to it. I have been working on getting the 2.75" intake tubes installed correctly. I also made some home made devil horns, not quite the same as the ones you buy, but seem to work good. Have get some more clamps. Thinking about some way to insulate the tubes to keep temp down.

 

Swap the sensors, put the V6 sensor in the V8 housing.

 

let me get this whole thread straight, it started out as tvt trying to give us more horse power , came close then they were banned? why is all of this? are we swapping injectors or sticking with stock? im getting eurocharged any day now and soon a bigger throttle body as well as intake eventually

 

Why was tvt banned? , the hp numbers also sound a bit stretched , I've done euro tune dcai exhaust sp ig spark plugs 74 mm tb and I would highly doubt my crossfire would pull more then 240 atw on a dyno! I might get it dynod soon to see! 6.5 seconds 0-60 stock yet with my mods best I can do is around 7-8 seconds? 2004 model limited any ideas? What's your guys 0-60 times with mods or not!

 

There are a lot of TVT threads on here. As for the banning...I believe it was over an issue of Truth...

 

Truth (or lack there of) and the resulting consequences.

 

oledco2u what is your elevation? that can affect your acceleration drastically , me in AZ no problems well the euro tune hasnt been done yet , but they promise like 20 hp , and that is significant , i almost dont believe it , but 20 extra ponies would bring me up to supposedly 235 hp , i really just want to get close to what a v6 charger, challenger, or camaro can do , they are heavier and have 300 hp , but the acceleration numbers can be met , the camaro is 0-60 in 6 seconds stock , we are at 6.5 , im sure i can figure a way to shave off .5 seconds. or .6 ? if we could match a nissan 350z of the same years that would be legit! they carry like 285 ponies stock
