![]() Plus, the turbo I decide to upgrade to may or may not be compatible with the down pipe that I chose to put on now. ![]() You can get defensive, I'm just glad to postpone a $1,000 mod until its needed. I would bet that my car as it sits would go evenly against any other S3 car with similar mods and that have the DP. It's not just Adam, its really a general consensus that the DP for the stock turbo offer VERY little benefit (Ok, I'm willing to drop the loss of power argument). Well, the DP isn't exactly the type of mod that you can "try with and without" and switch back and forth. The Fiesta motor just happens to be different. Many a car and a few turbo cars at a whole different level (Evo X). And I am not new to modifying whatsoever. I was just very surprised to find the results of this and wanted to share. Just doesn't make any sense.Īgain guys, I didn't come here to be combative. Likewise, I can pretty much guarantee that if I that if I throw the OEM DP back on that it will show up as a loss-whether that's in a higher wastegate duty cycle or in actual measured hp/airflow losses.Ĭlick to expand.Well, the DP isn't exactly the type of mod that you can "try with and without" and switch back and forth. I can almost assuredly guarantee that there won't be any loss in allowing the turbo more breathing room, even though I don't expect to see any gains either. I can't personally qualify specific parts on my car because I installed them all at the same time, but I will eventually swap out my Cobb DP for a catless DP and will be able to see if any difference exists between the two. Not seeing a gain with a downpipe but seeing a 20 hp gain with just a catback is and should be very questionable. Maybe it's coincidental and maybe it's not, but his opinion and testing, as a vendor, was 180 degrees out of what the community had previously tested at the time it was presented. But beyond that, changes that are made can very much make a difference for the better or for the worse. I could go into exhaust theory for days, but the fact of the matter is that the turbo is always the most restrictive component in an exhaust.that's kind of the point of it. LSx experience is not necessarily relevant here. While I understand why you're taking the advice you're taking, you're still just passing along information that you don't actually have firsthand experience in. The community has had a lot of people parroting information lately that have little or no experience on the platform. And it's a great investment for those looking for a turbo upgrade.Ĭlick to expand.I'm not saying you're trying to argue this is simply a discussion. If you look at our turbo, that's not hard to understand. He's just saying that our stock turbo does not flow enough to warrant a bigger pipe. He is not saying an aftermarket DP is a waste. If you are not interested in his opinion, at least let others hear it if it can save them some money. Adam is a great guy and always answers questions. ![]() Unfortunately, not everything is logical. No one thought that their money spent on an big name exhaust actually could hurt performance. And Flowmaster, although extremely popular, actually flowed less than the stock GM exhaust (baffled designs are designed for sound, not flow). Some exhausts that were too big hurt performance. When I was doing research on exhausts on the LS1 engine with my Camaro group, we did in fact find surprises. If you want more info, contact Adam at Tune+. With all due respect, I trust one of the top Fiesta tuners experience and opinion that has tuned my car and countiess others before.
