So I take the car out for a brief 10 minute ride a little while ago, before the big storm hits. I drive north a bit and see a few specks of rain on my windshield, so it's time to head home. I'm a mile from my driveway and it's warmed up, I'm in second and I just finished getting everything tuned up last week, so I think I'll stomp on it a bit. 4000 RPM, boost creeps to about 14 psi, and POP.

I do believe that was the end of that engine. No more boost, exhaust sounds like one rotor, and I got a nice tap tap of something trashing the rotor housing. At first I thought I blew a boost hose, but nope. I'm waiting for the car to cool down so I can pull the plugs and check the seals as well as to a comp. test, but it looks like beast v1.0 is officially dead for the summer.

 

sorry to hear that dude ...good luck with the rebuild.

 

Mods??

what are you using for a boost controller??

sorry about your engine,
Good excuse to get a large streetport and go single.
or 20B.l

 

N000B hes got a custom twin turbo setup... look in is avatar....


That sucks bout your motor, you gonna port it some(more?).

 

Ohh, man, not the new setup!!!

Don't have anything helpful to say, except that at least this road ahead has been paved with experience...

You stomped from 4k? Was it creep or one helluva spike? I'd go for the latter. What are...were you set to for boost?

 

Creep, spike, no. It was me playing with turning the boost up. I had everything stable and hauling *** at 13psi, I was going for 14. I got 14 allright It wasn't a det issue, I have plenty of fuel. I just think it was a tired motor... it was the original engine with about 70k. My boost controller is the custom made ball-spring type, with a ceramic ball. Works very well, very stable.

I did pull the rear leading plug and it sure is dead. I think I ate all three apex seals, cause I don't have even a puff from the rear. Front's fine tho. Oh well, I'm not at all upset about it... I was waiting for it to pop. Now it's time for a nice big port job. I actually hope that I ate the rear turbo, so I have an excuse to do twin GT28R's!!! It will be a while though, I don't have a lot of cash on hand right now.

 

im sure, ill be beating a dead horse..

but why???

why run two turbos nonsequentially, and do all the extra fabrication and work.
when you could have a very nice BIG single set up??

What kind of times were you running with the twin set up??
if you got that far.
