Mods to 400??
 

Alright guys I need some advice and/or suggestions.

I talked to the guys in the FB group (I know some of you are here) and I'm trying to get some ways to get just over 400 before I go with a supercharger.

I already know what kit I want, but it's smarter if I wait a few years until the car is closer to paid off until I drop $7k on it.

SO until then I'd like the car to have a little more. I have an '11 with an auto. I have a tune and axle backs and that's it.

What suggestions do you have and is it possible to get there and KEEP my cats. This is a big point of contention on FB that I'll "never" hit 400 without getting rid of the cats but I don't want to.

I don't want to deal with inspection (visual), finding quieter mufflers to go with an o/r pipe and I just really don't want to take them off and be breaking the law every day I drive it.

I'd appreciate any help guys. Thanks. :party36:

You could go cams, Boss 302 IM, HF cats and lightweight driveshaft. The driveshaft wont add HP but will be needed with the BOss 302 im for max gains/potential. YOu could always spray it. However since your just chasing a peak number there are way to get there since thats the only thing that matters.

I only need/want 25 or so.

Where can y'all point for me LT's with hf cats that won't rape my bank account?

Brandon makes a pretty good list.

You could replace the deleting the cats with a Boss IM, but to get better gains, find a set of mini CJ cams if you can. Getting full VCT control is going to be a big gain.

You can also just do Boss IM, larger CAI (Steeda, Airraid, JLT, C&L) and then spray a 50-75 shot and still be safe. lol But that's not a permanent solution, just when you have something in the bottle. Doing a lighter driveshaft and clutch will help to reduce the drivetrain loss, essentially giving you back power and TQ to the wheels you had previously been losing.

Long tubes delete the cats.

HF catted X is your best bet.

Agree.
this.

Reliable, cheap and fast. Pick two.


You get what you pay for in this hobby. Shortcuts or "cheap" almost always end up being more expensive than if you had done it right the first time.


My car makes 416rwhp/412tq with nothing more than a Lethal hpipe and a tune. It's not complicated.

Stay away from the Boss intake unless you get full bolt on supporting mods. It's a torque killer without them.

I actually agree.....:shakehead:

Yep, been here done this...just not with this car.

I won't delete the cats so high flow is my best bet.

I'm thinking LT's w/high flows and a cai. And back to HPP for an updated tune.



What can y'all tell me about he cams? I don't know anything about those in this car.

*clutch isn't going to do much since I have an A6.

Then what about the hi-flo catted shorty h pipes?

I don't think cams are worth it

Well, I will tell you this much. If you plan on boosting the car, you will need to ditch the cats at some point. The boosted set up will melt the cats, potentially clogging your exhaust and could blow your motor.

As far as the cams go, they aren't worth the money for the power return and tuning issues that come with them. The stock cams are very capable of making good power with boost.

They are if you find someone who knows what they are doing with the tune.

I agree. Unless an owner is trying to squeeze every bit of horsepower out of a car, they definetly aren't worth it. Clearly he isn't trying to do that if he's wanting to keep the car completely legit with the cats. It sounds like he's just wanting a fun street car that is "set it and forget it".

That $2000 bucks for the cams would be better spend towards a blower kit.

How much power does the car make now?
