Hey I'm wondering if I hold the record for the most blow engines in 5 months.... o and yeah this sucks...

P.S. It never saw the track.....

 

Well at least you have a quick turnaround

 

 

***...

 

What's the reason for your engines being blown?

 

Yeah, you running too lean? Change your fuel filter out? That's just ludicrous..

 

Neither... Fuel filter is new... I'm almost at the point to being too rich... we're trying to come up with some other reason that its killing itself. My engine blew just after being turned on and pulling out of the drive way
This sucks

 

WHo is tuning your ECU?

 

I prefer not to say the co. name b/c I don't wanna give'm a bad rap or anything... I dunno... I'm running a PFC though and I know its a good map since I've seen it work on otehr cars.

 

who is building your engine... better question what is the cause of the engine failures. Apex seals, coolant seals, when you open her up maybe it can help you find the route to your problem...

shitty though.. stay in there.

 

we'll the 2nd time it was due to 2 much boost that was making to much hp for pump gas which detonated and killed the engine... but this time though its kindof odd

 

insted of paying for like 3or 4 more rebuilds get a nice haltec or something just my suggestion

 

I was thinking 302 j/k naw man no dough I'm broke from the last rebuild

 

hey at least mines a 5 speed when it runs

 

I'd switch over to a Haltech - they run singles better and it adjusts itself with the amount of boost you run. Unless you have datalogit and a fyno for the PFC I wouldn't recommend it for a single. Check your timing maps up high (6500 rpms) - should read 40-41 up that high but PFCs come with maps reading 61 at 6500 and higher - enough timing advancement to detonate! Sounds strange.

 

ryker,

from the little we talked it seems like it could be that something is happening in one rotor and not happening right in the other. IE something not firing right or the injector is clogged. the difference in a/f ratio would be easily detected using even a wide band O2 sensor b/c its after these two exhaust ports combine into one pipe and therefore one reading. im not sure if you can do it on your manifold but you might want to look into welding an EGT gauge into each exhaust port and/or getting the injectors cleaned and flow tested to start.

Get a new mechanic. Also, send out your injectors out to make sure it is flowing properly. As for your Power FC send it out to XS to have it retuned.

 

I dont want to be an "***" but I am having probs with my car but there small when I think of 3 engines in 5 months. BAD reprogram from M-2, fuel smell inside car, now blown turbo seal. I WANTED to set mine on fire and be done with it but not now. Thanks.

I dont wont to sound like as "***: either..but you mentioned too much boost...well to me it sounds like you are not even letting some of the motors "break in"...

 

Hmmm...I made have had a similar experience myself last year before my old engine blew. M2, eh?

 

Other cars that have the exact same mods as you do? If so, it couldn't be the PFC. If not...

 

are you breaking in your engine at all?

In any case, I think I would find a new mechanic.

 

Yes the engine was properly broken in! 1500 miles below 3k and after that no rev's above 5k. I was only on 8lbs of boost... that shouldn't cause any problems... I seems to be a consensus that it may be my primaries (550cc's). I am thinking about trying to get them out before it gets to the shop but... my car is sick and it is sitting in a Apartment complex.... and they don't like it when I pull off my manifold and work on my stuff here... dunno why .
