The factory turbo inlet pipe is shockingly bad. Even a stock car would probably benefit from an upgrade.

 

It's a very common thing for manufacturers to use the intake pipes as a way to limit power output. They are also very concerned with sound, and likely do some of the shenanigans with the piping to keep things quiet. The packaging there is also VERY tight, so that may play into it a little as well.

You should see the intake pipe on my CTS-V. It even has a helmholtz resonator tube built in to quiet blower whine!

 

Interesting and more good info. Could there perhaps be any rubbing issues as I'm running 12 inch rear wheels on fat 325 cup 2 rubber?

 

If it doesn't rub on the inner fender liner you're probably fine. I don't have mine sitting here to look at but I don't recall it protruding any further outside the liner.

 

How much labor/how hard is it to install just the pipes?

paint is a terrible idea. These days though, it may be more than paint. A fancy thermal dispersant coating is a solid upgrade on intercoolers. Many companies make them, and I'm not comfortable recommending one over another, but you can find many instances of independent testing finding these coatings useful on intercoolers.

 

12 inch rear wheels here and no issues with rubbing. As Rix said, the intake pipes don't even press against the inner fender lining. You'll be fine. They are a very nice upgrade over factory, and are part of why my car made nearly 660 whp on E85.

 

That would be awesome!

 

Yes, a lot of people may find that very useful.

 

+1 very useful IMI.

 

Hi everyone
I am new on this forum. I am busy making a list of the upgrades that I want to do on my 997.1 TT I have been doing a lot of research on the forums here. My question regarding the DO88 turbo inlet pipes - what is the difference between the DO88 and the other ones on the market example the ones from Evoms ?

 

No difference what so ever. Just the price is different

Only other ones you can get are the Werks 1 carbon pipes or the ES Motor intake kit but you will pay even more.

 

ahhhh ok - that thought kind of crossed my mind but was not sure - well I am putting that on my upgrade list for sure. Hear good things about upgrading the intake pipes.
Thanks for the info !!!

 

I think it's a worthwhile upgrade if you are going to use aftermarket turbos at a later date but the cost involved vs the BHP increase is probably negligible IMO.

Let's see if IMI does this dyno test as it will be interesting to see the difference as I have had a set of the Evoms hoses in their boxes sitting here for nearly 3 years.

 

I agree - will talk to the tuners who are upgrading my car here and ask their opinion and hopefully if there is dyno test results posted - I can show them also.

 

How much labor on the install? engine drop?
