Just a quick update for you guys, the original engine decided it was time for retirement at 50k mile, and toasted a piston, turned out I had a crack in the intake manifold. So far new engine is in, and here is what its equipped with ;

Bottom;
Ross pistons .30 over 8:3.1 comp with coatings
Pauter connecting Rods
ACL tri metal bearings
All new oem pump,seals and oil filter housing
New arp hardware
Earls -10an 32 row oil cooler with -10 lines
Top;
Fully ported head with ferrea super alloys, and app goodies

Soon to come is pictures
I have changed other things on the car as well, got some 17x9 zigen zr+ rims with azenis rt615 245-45 17 tires, and a new suspension to boot.
This thing should scream fellas!

Crack in the intake manifold! What was the air fuel ratio when the piston cracked?

The log was all 11.5- 12.0 egt's were fine, no knock, on 15psi, i didnt figure it out till i pulled the head and the piston was missing the top of the crown, totally mystified me.:confused:

Any more updates, I love your car. Would also like to know how close to the 200 mph mark you got! :D

You can melt pistons and not knock, knock is a timing issue, at every a/f ratio there is a theoretical timing value that the engine will not knock at. You can run a car lean to melt and still not have a knocking issue which is why people run 4 individual EGT gauges.

As for the ARPs, good luck...i'd have dumped them a long time ago.

K man nailed it right on. As usual. This is why I frown when people overlook there EGT's and only rely on there wide band.

I'm PRETTY sure the cars running the Texas mile trapping 200mph+ are not running/monitoring EGTs' in every cylinder. I know the 228mph *record holding* Supra wasn't. EGTs are 90s technology. To me...they are pretty damn useless as far as tuning is concerned. I am sorry, but the tempt. reflected on that gauge (if placed in an exhaust runner) does NOT neccessarily depict actual tempt of the combustion chamber at that particular time. That's a big con on that monitoring device. Tune the car on a conservative afr and you will not have to worry about tempts high enough to melt a piston. EGT gauges are not a pre-requisite. Give me a wideband over a crappy EGT gauge anyday. :)

You need both. How are you suppose to tell if you are starving the other cylinders, having injector issues, fouled plug, etc, etc.

Duh...you inspect the plugs. :rolleyes: That will tell you everything right there.

Narrowband O2 sensor downward trace will also show/indicate misfires. No crappy EGT gauge needed there. :) Don't tell me "You need both." People have been tuning just fine without them. It's not the mid-90's. ;) :)

Breaking pistons and throwing chips of valves is not "just fine" Not all of us have black nitride coated valves.;)

I'm done cluttering some ones thread.

My first thought was "thats the worst 60ft time I have ever seen". Then I remembered your fwd and making crazy power. Didn't your car used to be a n/t 1.8l or something like that, I think I read that in an oldschool thread awhile back?

Does Mavisky know you swiped his flares? Dude might come looking for them.:D
