I have an 07 tc with a s/c and 9.5psi pulley with the trd reflash of course. I want to get the Weapon R intake for it but people are telling me that the car will not run good and will run very lean and i might blow something up b/c of it unless I get a piggyback and get it tuned. Is this true or can i by this intake and just bolt it up and be good to go? thank you

 

Yes its true, however some people have installed an air and fuel gauge and seem to be getting good enough numbers, so if you must I would get an A/F gauge first, then put the intake in and see what you read, then you'll have the choice of leaving in or taking it off.

 

come on people
I have the same set up. Would like to hear about experiances with this weapon R intake.
Pros and cons.
Good thread brsciontc

 

I have an a/f gauge and an intake. Had it like that for a while now. What would you like to know.

 

you need a piggyback tune because at WOT, your a/f ratios will get alittle lean. so it is much easier and safer to just get some tuning done (which will also net a nice gain in whp) than it is to just bolt it on and take your chances.

 

Nah ah. I see high 11's under WOT.

 

he is asking specifically about the weapon-r intake, you aren't using the weapon-r intake, so it isn't quite the same thing. the weapon-r intake, when it came out, they released dyno's with A/R's and they were alittle lean for most people's comfort.

 

what were the af/r's with the weapon r under WOT?

 

I had the Weapon R s/c intake. WOT was OK since the MAF doesn't play as huge a role. Normal driving was terrible. Trying to maintain speed or light throttle and the AEM A/F gauge would read off-the-scale lean "---" and the car drove like crap. As soon as I stomp on the gas everything went back to normal, until I try to maintain speed.

the dyno's aren't there anymore, but people were arguing that 14.7 is "damn near perfect" while others were saying that anything over 12.5 to 13 is dangerous etc etc.

 

so the af/r at WOT was 14.7 untill 4000rpms? but what was it after that. And that is very very lean for WOT btw

 

Right now i have a k&N filter in the trd air box that came with the kit. I think im gonna stick with that for now b/c what you are saying the car is running very lean i might blow my motor so i dont think this intake is such a good idea.

 

I gave the intake to someone else and it worked fine for him. I just don't think it's worth the money for something that looks that ugly and is hit or miss, lol. I'd either stick with stock or modify one of the other intakes. You can even try one of the ebay short ram intakes. CAI isn't recommended on forced induction, and doesn't provide any benefit since the process of compressing air produces heat anyways.

 

I think before i get the intake i am going to get an air/fuel gauge to see what im running at now. Then i might try to find a cheaper one like you said and see how it is.

When you say you gave your intake to someone else and it ran fine did it still run lean and just good or were the af/r's also good?

 

well...there are gains made by swapping the factory air box with a conical filter, and while compressing the incoming air does create heat, sucking in colder air from outside the engine compartment than the hotter air inside. while it will get heated up by roughly the same amount, there would be a tiny net decrease in the intake temperatures wouldn't there?

 

As far as I know he didn't have any A/FR problems. He doesn't have the car or intake anymore though.

 

ok so..
if i get a wait to install the intake untill i get it tuned with the greddy emanage. i will be fine.
thats what im getting out of this

 

Most of the time tuning is for WOT. I was seeing problems when trying to maintain speed or during light throttle.

If the tuner is using a dyno like Dyno Dynamics he should be able to test the tune at light to partial throttle while on the dyno.

 

I can see where you're coming from. Not sure if there would be much of a difference. Something else to think about is how the length of the intake tubing could affect performance. I look at it like drinking through a short straw compared to one of the "crazy straws" and how it takes more effort to move the same amount of drink with the longer straw. I know it makes a lot bigger difference with turbos, but would imagine it could affect performance on a supercharger.

 

I was going to have Ptunning dyno tune my car. So what ever there process is? Is that something to ask for.
