Like the title says. Has anyone on here done just a ported blower and throttle body without anything else? Based on these two videos, it seems some decent gains are to be had by simply porting the blower, even without a tune. It would be nice to hear from an owner that has actually done this rather than a shop.

I wouldn’t do it without a tune.

Yes, members here have done this and gained approx. 40 hp. I do not believe a larger TB is necessary for this build (my OEM TB made 725 wheel), but an updated tune is highly recommended.

When it comes to the stock blower my thoughts are this. If you are positively, absolutely, 100%, without a single doubt sure that you will be satisfied with the results from modding the stock blower (pulley, porting), then go right ahead and enjoy it. However, if you think for even a second that you will want more power, then do not touch the stock blower. Save up and upgrade to an aftermarket system.

Now the reason I say this is because in the past, there have been many people who have gone this route...they went with modding the stock blower and then swapping to a different one. End of the trail after looking over everything they all said the same thing...that the stock blower had cooling issues, was limited in power/potential, etc. And they all said that they wished they switched to a different blower before they spent all the money they spent modding the stock one. so just spreading that general idea from those who have gone this route, if you think you will want more, then just do it all the right way the first time and upgrade the blower.

Now if you are sure about upgrading the stock blower then there are several companies that offer good prices for going that route. Some are more popular than others but they all have roughly the same prices and results. I suggest you do some intense research, speak to some of the more qualified members on here who can explain exactly what you will be dealing with if you stick with the stock blower vs upgrading, and then make an informed decision based on your desires and what each route has to offer.

Whichever route or vendor you go with, good luck.

Thanks for the info. I don't even want to modify the car at all, I was gonna keep it stock, but if some gains can be had so easily, and not be detected, then what the hell. It's either some porting work if it's worth the gains, or nothing at all. Definitely don't plan on spinning the little blower any harder.

I see you have a GT500. LOVE that car, you just can't seem to come across one for under 90K

I'm sure some people have gone that route without a tune. But IMO you really would need a tune which will be detected and will void your warranty. Or they'll inspect the blower and find that it was ported and they'll void out your warranty. Trust me, these days these guys are pretty sharp when it comes to inspecting cars for major repair work. If the warranty is your concern then unfortunately you are stuck with simple mods like CAI and catback and that is pretty much all you can do.

I was under the impression that you had a GT500 also based on your avatar. Yea the Shelby is a really awesome car. It has tons of top end power and pulls like a monster up top. I was actually able to get mine for under $90K believe it or not. But mine is used so that might be why. All the new ones are selling for over MSRP. At best you can get a used one with very low miles at original MSRP. It is worth it tho for this car!!

lol you have wideband O2's with a little porting. more than enough for the car to self tune and be 100% safe.

[synolimit]

i dont think its worth $1700+. thats insane.

I’m assuming you’d be doing it for more power. You’d make more power if it’s tuned. Depending on how much it’s ported you could run the engine lean without a tune. Why take a chance on hurting your engine? If you only lightly port it you won’t see much if any increase in power. Hence my opinion, I wouldn’t do it without a tune. If I cared about warranty I’d leave it alone.

But you do you. Port it and run it if you don’t care bro.

Nah, I wish I did. Tried to buy one for a few years, I just can’t swing it between the mark up, then NY sales tax on the new, inflated price. The ZL1 is much cheaper, and still a car I like a lot. For the nearly 20K savings, the ZL1 seems like the better bargain

Well, for a "Furd" Shelby GT500 with a supercharged 760 HP engine, 7sp DCT, and comparably equipped to the ZL1 and HC RE. The HC RE is pretty much over $90K and when I optioned one out the way I'd like it, the price was actually $98K. So to get a GT500 that has similar features, is similar in the quarter mile, handles better, and retains it's value, to me that's a good deal. But to each their own. Once you own multiple platforms of high performance cars you will know more about them and be better able to compare how they are.

The ZL1 is a great car and I love mine. I'm also making considerably more power in my ZL1 than my other cars and it is by far the fastest one I have. GM hit all the right marks with the ZL1 and I always say I doubt any manufacturer can match what they did and at the same price.

But the GT500 is also a very awesome and powerful and fun to drive car. You can't go wrong either way if you ask me.

What is your experience between the two? What feels better or worse than the other? Just curious

I had a 2020 GT500 CFTP for about 6 months and stock for stock its better in every way vs the ZL1 but since it was worth 20k more than I paid I sold it for 125k instead of driving it.

For 70k the ZL1 is really hard to beat, I feel great about driving it as it won't cost me 20 grand in pretend inflation value if I put some miles on it. With a couple mods it really wakes up and of course with a lot of mods it can make 1000 just like the GT500.

I don't miss the GT500 one single bit and I enjoy driving the ZL1 quite a lot. It has its own advantages vs the GT500 also, just not sound/performance type of things. More like intangibles. It really reminds me of a 4 seater version of my Z06's but also doesn't handle as squirrely either. It's an awesome street car.
