Well, i never thought it would happen, but my peakboost manifold cracked last saturday.

I am posting this because I have had a very easy time dealing with www.cheapturbo.com (phoenix turbo) and wanted to share this with everyone.

I explained to them that I Really need the manifold by this friday (4 more days) and they are working with me to get me a new manifold by that time.

wow...that must have been a one-off fluke, I don't think I've ever come across anything negative about Peakboost's manifolds.

good to know they're doing what they can to take care of it asap

I bet any money something was hitting against it...

Look at your clearances, imagine the radiator or something tapping it every few seconds/minutes...that is what would have caused a break. At extreme temps, that would probably be one of the hottest spots too...

I believe it was placement, personally.

Goodluck getting it fixed/changed out, it shouldnt take long, they are good people at both peakboost and cheapturbo.com.

thats the first time i have heard anything negative on a peakboost manifold. How long have you had it? still thats only one broken manifold out of how many and how many reviews?

Does your wastegate plumb back to your downpipe? I could see how that crack could form with continuous cooling cycles esp. if there was a lot of tension on the wg after bolting down. It might be a good idea to revise that part of the piping so it doesn't happen again.

Either way the radiator tapping against the manifold shouldnt be enough to ever crack that manifold. The radiator is SOOOO much softer than that turbo manifold any tapping against the radiator would break the radiator a million times before the manifold should crack. For me ive seen a lot of "high end" manifolds crack and several times the makers have stepped back and basically said too bad. They should be replacing it for you for free since thats one of the reason everyone chooses a much more expensive manifold but if they make you pay then youre probably better off with a different brand

That just goes to show that even the best brands have their fair share of faulty products. It's the really good companies that know, understand and stand behind their products when someone does get a fualty one. Good to hear they are helping you out.

Yup they do..

Hmm, do you properly turn off your car all the time?

With turbo cars, you always have to wait 30 seconds and let it idle before turning off the ignition....bet ya didnt do that a few times....

Anyways, whats happened, happened, its getting resolved, dont worry about it.

Thread done, lol.

In all my boosted cars I let the wideband warm up before start, start the car and not move it an inch till oil pres builds up and the car warms up for a min or two.. then when I'm finished ready to park it, depending on how hard I ran it, I manually turbo time it [leave it running] for 30 sec - 2 min to prevent the oil from coaking up n the turbo.

Of course I could just be retarded.. Its just a habit, I'm sure someone told me do that crap when I first got a honda boosted and I've done it ever since.

Could have happened because of high EGTs... possibly..
I have had 1500f egt at end of the track for 10 or 11 runs steight with out any issues. Unless the manifold is getting really hot then getting hit with cold water, I do not see how EGT would effect this.

WAWA(92) 1300f usually
C16(116) 1150f usually

As t4 already pointed out, that has nothing to do with the manifold and everything to do with letting the oil drain from the turbo and prevent coking. Pretty basic turbo info.
