    Looking for a bit more power. Currently has 465whp with 2.76 pulley, Jlt intake, cat-less x-pipe, exhaust. Looking to do Mac longtubes and accufab Tb. Anyone have any idea what kind of power gains I will get with adding those two mods?

    I agree with putting your money into other mods. LTs give nice sound, which is why many go that route. But you can do much better with your money, power wise. You could consider porting your Eaton for a gain of another 50rwhp. If you have no intention of ever upgrading to another blower (ie. VMP, Whipple) then porting your Eaton is recommended. With a good tune, that would put you at around 500rwhp with that 276 upper. Add a 4 lb. lower to that combo and you're looking at maybe 520rwhp or so, depending on your tune (93 octane fuel). E85 fuel (not available everywhere) is a popular power adder, too. Bear in mind that as you progress up the ladder, you'll need to make more fuel system upgrades. If you're looking to just keep it as simple as possible, my recommendation is port your Eaton, add a 4lb. lower, do the requisite minor fuel system upgrades to handle increased fuel needs, and get a good tune.

    •Easy but likely to fail within a short time is a dry 75-100 shot or wet 150 shot. $1250 or cheaper, but it’s like fast and the furious, amatuers don’t use nitrous oxide.

    •Best choice money and gains, 2.3 TVS swap. Plan on $5k, you’ll have money left and feel very happy with the 600-700whp. Do fuel and cooling work, don’t go too cheap.

    •worst choice but my favorite (unless you can wrench very nicely and like getting your hands dirty) custom single 76 with flipped manifolds, and so on. This is not an option for a shop build and any semblance of a budget. It’s competent home build or get screwed out of $10k territory. But done right, you’re looking at your time/research and $2-3k in parts new and used. Upto 800whp+. The fuel, spark, and so on will dictate how much power it makes and how reliable it is. Difficulty rating 12.5/10 for anyone accept an experienced wrench. 6 or 7/10 if you know what a turbosystem does and have worked on them before.

    Bottom line, go TVS. Its medium priced to do it with fuel and spark mods, but is indeed the easiest and way to hit 600-700whp. The turbo approach can ultimately be cheaper and more reliable, but you have to have experience to get it right. Guys that have built a turbo Honda or srt4, then turbo Nissan Z or evo/sti then tackle a home turbo cobra do pretty much fine and don’t spend much at all compared to the results. Guys that buy the catalogue and pay a shop end up with complications and unhappiness more often than it “should” happen.

    Scratch the ported Eaton off the list. Gains are minimal. Look for a 2.3 Whipple or tvs there’s been some good deals.

    Thanks for the input! Been thinking of used blowers. My tuner actually said the same thing to skip a port job and go for a Whipple or vmp

    I just really like how the car feels right now and I'm afraid that upgrading the blower will take away from the drivabilty it has at the moment

    It won't. Well I never drove a factory blower car so there's that.

    But you wouldn't even know my car had a supercharger at all if I didn't get into it. I bought mine after a 5 min test drive and drove it from Fresno to El Paso. Smooth sailing on CC

    That's been debunked for almost 15 years now. That's the beauty of these powerplants, you don't have to mess with internal changes like ported heads or lumpy cams...those can remain 100% factory and you still make stupid power with a blower swap. As long as the fuel system and TUNE are up to snuff, you'll never know the difference until you mash the gas.
