I feel sick after reading that. I guess you found the limit for the stock rods. I was kind of wondering why you where using the stockers. On a Plus side 526 on pump gas is awsome.

man that sucks! Sorry Swanny, I know how hard and how many late nights the whole crew put into that beast. I am sure you guys will get it up and running in due time, when it's all ready for the next step. Keep you head up, it's only a car.

I just have one question for you Swanny. Were you just trying to see how far you could push the stock rods? Because I can't think of anything other reason that you would leave them in considering the turbos you choose and the power you wanted to make. Just doesn't make sense.

Other than a bearing going I would have to assume it was detonating on pump gas on high boost. I know you said the A/F were good but you could have just been pushing the boost on that gas too much, or running too much timing.

Oh well I guess you will just have to diagnose it when you take it apart. Speculating is just that, speculation. Either way it sucks.

Of course he was checking the limits. I done heard it from the horse's mouth.

I just wish i could have gotten a ride first!! :)

good ruck!

For those that care:


Cylinder #3 doesn't like me anymore. Last night we made 519awhp at 22psi, very safe tune. Then we decided to turn it up a bit. It made 526 at 24-25psi...the car seemed to just go "flat" after spool-up. Safe a/f ratios, no knock, low timing (16 degrees advance), a very safe and monitered tune, almost like you'd see with doctors watching someone in the ICU wing of a hosptial.
16 degrees of timing advance on pump gas and 24-25lbs of boost is nowhere near "low timing" unless you are running a really low compression ratio (in the 7.5:1 range). Don't you guys think timing should have been set in the single digits when running that much boost on pump gas? I could see maybe 11-12 degress but 16 degrees just seems pretty aggressive to me for not using C16 at that boost level.

I've been running 15 degree's of timing with 26psi on 93oct for probably 8 months... at least 50 pass's down the 1/4 before switching to race gas. (only 4 runs then blew the tranny on a really bad wheel hop launch...lowered it 1000rpms due to really bad wheel spin didn't notice I was the 3rd car in line after they reprepped the track)

Thats great. But would you consider that "low timing"? I would consider 15 degrees at 26psi pretty aggressive. If he is running low compression then it could be considered "low".

Actually 15 is on the high side for me. I rarely get more then 16 at it's highest so ya 15 would be on the high side.

Anyrate hope you get things back together soon.

Before I left, before the injector O-ring thing:
Shrep thought he heard a miss-fire or some such on decel and idle. I didn't hear it, but it would mean that it's not your "power pull" that should be blamed. The pump tuning aside, that is nowhere near enough power to break things.
