Mods to 400??

[GTOphil]

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?

[DirtyD]

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.

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.

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?

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.

[Grandpa]

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.

Not sure what you are asking...but if you are talking about replacing the factory manifolds with shorties and high flow cats, I've heard people say that shorties compared to the factory manifolds aren't worth the price.

I don't think cams are worth it
Comp cams aren't worth it, but the mini CJ exhaust cams for these cars are definitely worth it.

You of all people know that comparing one car's dyno numbers to another's don't mean anything.

Mini CJ exhaust cams can be had for under $400....

[Grandpa]

My point was that his goal of 400rw NA is very easily achievable withminimal mods.

There is more than just the cams that need to be purchased for that installation, but there is also the cost of installation itself which is very costly. Even still, it's minimal gains for a lot of money.

[DirtyD]

Yes, it can be. But by not deleting the cats, he is making himself find a more difficult route to obtain that.

Yes, but even then, Frank bought everything he needed for the cam swap from Nic for $350. Cams and springs. Grant it he did the install himself, being a mech, I would imagine if you had a decent amount of mechanical knowledge, and offered to help while learning, someone would cut you a deal, or getting a buddy to help. It's still a setup that could be completed and installed for less than half what the Comp Stage 3 costs alone, for roughly the same gains.

380

[GTOphil]

I know everybody is going to say get rid of the cats...but I'm just not willing to do that right now.

When I have the money for a s/c then I'll revisit that, but it'll have to be high-flows for now.

I talked to Jason and got a price for LT with hf cats. Seems like that an cai is my best option to not spend a ton of money, but add some more power and sound for my street/family car since it'll be a while until I can actually add SIGNIFICANT power.

[DirtyD]

Getting a full 3" mid pipe, whether it be an X or H, might free up a bit of flow that the baffled and restricted stock mid-pipe takes away. Adding a CAI and a decent set of mufflers with a good flow through design might get you close to 400whp.

I can't agree with you. I'll just leave it at that

[DirtyD]

I can't agree with you. I'll just leave it at that
I'm just stating what I've heard echoed from people, that the Coyote doesn't really see much gain replacing the factory manifolds with shorty or equal length headers. Most people have gone LTs. I don't even think I've heard a single person running shorties on our motors.

Not saying all shorties don't do anything, just these motors.

I kinda agree with you on that lol I'm talking about the cams.

and I was talking about LT's with a SHORTY hpipe with cats. Not shorty headers. Putting shorty after market headers on these things would be dumb

[Bacadiesel]

Why do you want to keep cats tho? Mine passed inspection legally with longtubes, boss manifold, exhaust cams , off road x and tune making around 465whp.

Legality and hassle. I really don't want to keep having this fight. It's my car.

Places around here do visual inspection, you can get a ticket for it (I don't care if y'all say you never have) and I'm not the kind of person who's going to slip somebody money just to make something pass if it doesn't.

[Bacadiesel]

I didn't pay someone illegally to pass my car. I went to the nearest car inspection place and told them I need an inspection. It passed 20 min later. $39.75

Sorry not trying to be rude was just trying to help

Im actually with you on this subject. I dont want the hassle either. The problem is that if you do it "legally" its going to be more expensive and that is something we both have to come to terms with. Lol

Better break out your wallet.

Well...that's one. HAHA!

I'm going to spend the extra $300 or so for high flow cats, I'm fine with that.

I talked to Jason at Hypermotive and I've decided in a bit to go with some LT's and high flow cats. Then I'll add a JLT cai (not his suggestion, I just like it though I'd love to find a CF one for sale) and put them both on and get it tuned.

I know it might not be far over 400 and, yeah, I guess there's a chance it still doesn't but I'd like to think that with LTs, high flow catted h (x if I have to), CAI and a tune that it'd run with my old GTO.

That's really my goal. To get the car where I can enjoy the sound and extra power and not be slower than my old GTO for years until I can afford the TVS kit.

Think i'll just keep my ass in the sticks where it's still $14.50

LOL, but it costs you $60 bucks to go or anywhere that doesn't have cowtipping for entertainment. :rofl:

Eventually DFW smog will get bad enough to include the Tyler area in the smog testing zone and you will have to pay $39.75. lol

I'm sure they will consider Longview the same affected area. lol

What is inspection?
