What boost are you making? Depending on the amount of boost and the timing your running Wons are the weak link if going for more.OT AFR should be mid to low 11's. A stock 346 can make 500 plus force fed if the tune is spot on w/out much worry but the stock rod bolts & pist

AFR should be at 11.5 in boost.....I run a bit leaner from 1-3 psi

i am at 15psi 14*. But my afr is 12.5. I thinks its to lean. I wanted to see what everyone else was running on theirs.

That is WAY to lean....12.5 AFR is for NA motors

I know just think what it was in 3rd gear. i bet 13-14afr when the gasket poped.

You pulled on a stock bottom end with afr that lean

Your motor is going to explode soon if it hasn't already

haha no crap!

We all thought we where in 3rd gear when it was tuned but the shifter ended up being off a little and we where in 2nd gear. I would not have run the car if the afr was that high!!! I just hope i got lucky and blew a gasket and not something else!

think its safe to say the tune was off just a little bit.

We tuned mine way rich to be safe. It's stock top to bottom

AFR was 10.3
Boost 10.5 #s
Fuel E85

Made 500 rwhp through an auto and a 12 bolt. Prolly coulda made a little more by leaning it out, but better safe than sorry. Hopefully have a new motor soon anyway.

Was that with pump gas or race gas?

iTrader: (25)

I was wrong, on our last run he added 6% of fuel that gave me 11.8 afr. I was on 93 pump gas.

I guess cylinder pressure could have blew the gasket out?

PSI= ~8lbs on the gauge
Timing= I'm Sorry i don't remember the exact number, i know it wasn't crazy, tried to keep it safe.
Octane= 93 pump gas
AFR= ~11.0 WOT according to my wideband gauge
HP= 595
Turbo or SC= Procharger D1
Stock Head Gasket= Yes, GM MLS
Head Studs or Bolts= Bolts (not even ARP)

I had the tuner keep it rich and used 317 heads to drop compression a bit, trying to be "safe"
I used the EPP cam, so I used the Patriot Gold dual valvesprings (.650 lift) in the heads.
Heads are untouched other than the spring kit.

Stock bottom end has held up so far, i also don't beat the crap out of the car, and i have only been to the track a few times.

FWIW...

Went 10.4 at 132 with 6 speed and 12 psi with 1.48 60 foot.
Went 10.4 at 128 with Built th400 3200 stall with 12 psi with 1.40 60 foot.

Current setup in my rx7, L33 5.3...

PSI=18
Timing=14
Octane=e85
AFR=11.5
HP=686 (thru the auto)
Turbo or SC=? TC78 turbo
Stock Head Gasket=? ls9 gaskets
Head Studs or Bolts= head studs

Also had this combo before in my car and maxxmitchell's car, LM7 5.3...

PSI=11
Timing=20
Octane=e85
AFR=11.5
HP=560rwhp range through an auto at 11lbs
Turbo or SC=? TC78 turbo
Stock Head Gasket=? stock
Head Studs or Bolts= stock

When it was in maxx's car he ran 14.5lbs and 26 degrees timing, never pushed coolant on him. It finally pushed coolant on me at 13lbs and 20 degrees timing, but I think it was due to a tune change and missed something, got lean on us. Motor is still together and is my spare motor, after it pushed coolant I drove it another 1000 miles.
