COBB SRI/TIP problems?

[blackdragon0731]

Read on SU's site that some reviewers had an issue with the COBB SRI/TIP combo when they were used together, getting funky ass power surges up top in the powerband, I'm currently sporting a pro-tune, but don't want this issue. Has anyone else had this or heard of this? It was only 2 people who mentioned it in reviews so idk the credibility of it. I'm going to be investing in the COBB TIP soon. Any input would be awesome!

At least 30k miles with the full cobb set up and no problems what so ever.

Okay cool, and I am already running a pro-tune... so I'm hoping I wouldnt have the issue either. Good first response! Anyone else have input!???

I don't have that intake, so I can't personally respond. There are several threads on the MSF board about this issue. Those who were having the problem with power surge under load at high rpm seemed to have resolved the problem by removing the Cobb TIP, which seemed to be the issue, while keeping the SRI. They either went back to the stock TIP or used some other aftermarket inlet. Check over there if you are having the issue. If not, I'm a big believer in the philosophy of "If it ain't broke, don't fix it."

Well I haven't invested in the TIP yet but I want to, I'd like to have the whole Cobb intake setup, after that all it'll take is a turbo mani and I'd be fully bolted. So just trying to do my research.

Well it seems like the guys only have the issue without a tune... I have a tune, so I should be in better shape to start with. I'm pretty excited to get rid of the bad inlet that's on the car stock... I really dislike the design of that piece, plastic, stupid pancake design, terrible dents and bends in the pancake section to boot... *shudders* and most of those guys have said theirs was loose no matter what they did or how tight they got the clamp it could always just pop off. So, I'll go ahead with the Cobb TIP and finish out the full Cobb intake to turbo setup.

I recall some discussion that the Cobb tip and others like it that have significantly larger tubing size than the stock turbo inlet cause problems. Necking down a giant 3" TIP so it fits on the relatively tiny intake of the turbo housing causes turbulence and a loss of power. Ideally it should be the same size all the way to the MAF meter.

Ok the Cobb unit isn't one with this problem - I want to correct myself. The CPE unit - maybe.

Only other issue with Cobb and your setup is the air straighteners in some of their MAF housings were warped causing problems. They are molded plastic.
