My motors snapped a tip

[bobert]

O yes its happened again.
I left my girlfriend’s house last night and I thought I would go out for a play for a play in my rex, after a bit I got board of driving @ .80 bar so I turned the boost up to 1.2. It all seemed good, the car was pulling hard and I was havin fun until I nailed it hard out of a corner and then it just died.
It was like someone had just flicked a switch and killed all my fun, I am 99% shore it’s snapped a tip and I will confirm this when I get home tonight.
I am gutted because the car was for sale.

What kind of fueling system are you running ?? Sorry to hear its happened again.

850cc primaries & 1600cc secondarys

I have not had it mapped above .80 bar. And I was running at 1.2-1.3 last night, my fault really I should of bought wide band then I would of known my a/f/r’s.
I’m shore its ran lean.
O well these things happen, the engine is coming out tonight.

[antnicuk]

its bad news its happened again,  but running 1.2 bar is risky enough but doing it without it being mapped is bound to end in tears.   1.2 is fine for the drag strip but constant use at that boost on pump gas and it wont last long.

I wouldnt run mine at only 0.9 until it was mapped when i changed the i/c, its just too risky with a rotary, you dont get a second chance like you would with a piston engine. First sign of det and its usually dead!

[bobert]

the engine is out.
i had a look through the exhaust port and one of the front rotor tips is missing its also made a mess if the rotor.
i am going to strip it down tonight to find out the real damage.:mmmm

damn someone who has more bad luck then me in the engine department, Rob from what im reading tell me if im wrong you drove it at 1.2BAR on a umapped boost zone?

yep
I didn’t want to push the boost past @ .08 bar after the rebuild, I haven’t been back on the dyno from then and I didn’t buy wide band.
Anyway I’m going half bridge :yes

[ashc]

i\'d love to be able to scoop my engine out as quick as that, good luck that man!

you areeee crazzzzzyy dude lol
If you going to go half bridge make sure you put a bigger rear exhaust housing on your turbo thats what killed my engine this time tooooo much heat build up due to my rear A\\R being too small for my half bridge

[bobert]

I stripped the engine down last night and I haven’t got away lightly:Grrr .
All three tips are chewed up, the housing is fooked and so is the rotor.

I’m now on the look out for some parts

[ianelvar]

You maniac! In the nicest possible way. I\'m glad other people do crazy stuff like that because they get bored. Sounds like something I could have done..

[bobert]

[Lum]

Thats almost identical damage to what i did at rotorstock mate!
Only i chipped a tip on the other rotor aswell!
Good work on turning the boost rite up!!  :King 0.8 bar to 1.2 cos you were bored! Excellent :3gears-rh

[Rixio]

You Mad B@stard! from 0.8b to 1.2b - Good to see your still in good spirits though :Thumbs-up

[gsb876]

Damn !!!

At least you know why it happened Rob, cant really run 1.2bar if its not mapped for it dude :Nono!

Hope you get it running again asap mate :cheers
