In the midrange and up untill 5000rpms it was too rich. The cars behind him saw black smoke (fuel).

Did he get this done at the Drive-thru Dyno?

I'm not the best one to judge what really happened here, but something definantly sounds fishy here. Either way, I don't think the guy should have to pay for the engine repairs.

Engine builder says it was tuners fault, that should be addressed with the tuner. The tuner should be liable for something if he let it drive off his dyno with a crap tune. If it was running that rich, it shouldn't have run worth a flip, and pulling the appropriate amount of fuel should have cleared up some of the starving issues.

If nothing else, the work should be covered simply for a PR issue especially with all the bad PR going around for ya'll.

ARE tried to sort this out months ago, but I think we are finally getting somewhere. We're going to have to finalize this week to take care of Lyle. I wish we did this earlier. I have been emailing Quicken on the side. Thanks

I dont know how important this is... but it *doesnt* take that long to wash out rings. I'd say a 150 mile drive, at one consistent rpm, getting *way* too much fuel, would totally kill a new set of rings. Kill'em dead.

When I bought my new motor from MTI, I discussed break in with Jayson for 30 minutes. He warned me that running with a bad O2 can be fatal in 15 minutes (washing out the rings) and that I should not keep the car at one RPM for more than about 30 seconds (if I had to drive on a highway, speed up a little, slow down, change hears, etc... but he would rather I didnt)... otherwise I would create improper wear in on different parts of the cylinder. Also, he said if I wanted the engine to last for 100k miles, not to run over 4500-5000 rpm for the first 500-1000 miles.

Just as an observation... but that dyno and then the 150 mile drive could have killed the rings.

Yep, it won't take long to kill the rings and possibly mess the cylinder walls up running super rich.

Here is an example of a stock fuel pump car running deep 10's (10.3x as a matter of fact heads/Cam/Bottle) Seems like some year stock fuel pumps might handle more than we give them credit for.. https://ls1tech.com/forums/showthrea...447#post851447

I guess I should have learned more about projects like this, its really my fault I guess. I did ask Barry if the 150 mile ride home was OK for break in, or should I trailer the car home and break it in driving in the city. He said it was just fine on the HWY as long as I don't cruise at one set rpm for long, so I was up and down and all over the place with the rpm's all the way home. I just don't know what esle I could have done after the motor was tuned and run on the dyno and checked out fine as far as O2 readings go. Ed Wright and Mike spoke many times and they both say the tune was within the correct perameters, so I picked up my car and took it home.

Either way, Dave DiLuca has e-mailed me and told me what I need to do about having my motor possibly sent to them, I'll talk to Wade on Monday.

Look, I bought the motor from them because they build the baddest motors out there, having it repaired by them will make me happy as a clam.

Question:
How can a motor check OK on a dyno, wideband O2 and a scanner, yet still be rich enough to wash the cylinders?

Quickin

Thing is, Ed Wright tuned the PCM, Mike Norris just checked it on his dyno to make sure it was all good.

CHRISPY

You can run extremely lean at WOT and still wash the rings at lower rpms. Fuel starvation up top from not enough pump and too much injector without proper scaling down low and at idle.

Ahhhhhhhhhhhh...... that's what I needed to hear!

Now that makes sense!

Thank U!

Quickin

Hey Dave, I appreciate the help breaking the ice, Wade and I have made contact and it looks like I'll be sending you my motor for warranty repair.

You have no idea how relieved I am.

Thanks again

Glad you gave them a chance to look at the motor

Who else is better to work on it, right?
I feel lucky its working out, hope to be
again soon.

This is an argument for vendor consolidation, or as I learned from years of running computer departments, buy as much as you can from a single vendor. Great insight after the fact, but it leaves with far fewer butts’ to chew. It also lead to us building engines as well as providing the tuning, we had too many customers asking to get the whole package at one place.



Funny how a bunch of motorheads and car-guys understand the concept of avoiding being an integrator better than CIO's (Chief Information Officers) of huge companies do...

Quicken, no problem. I will get back to you regarding the nitrous email you sent me tonight. But that cam you have is identical to the one we went 9.25@155 in the C5 I suggest a TNT ring and 150HP to start, then maybe 200 later on. You won't need more then that.

We have A local customer has the exact 436 motor and cam you have with a stick C5. It was going high 10's on the motor at 130-131 and mid to low 10's at 142mph on that TNT 200 shot sideways down the track with tires on it. Can't hook it!
See if you can get a TNT ring and we'll help you out.

Scott, I like when a customer sends us the whole car for the motor and tuning. That way we know it is our setup when it leaves with a safe air/fuel ratio and everything checks out right. Thanks

Glad this has worked out for both parties.

Nice job ARE !

I agree it's good to see this working out.

Quickin

I don't know what a TNT ring is???
Where do I get one?

Dave,
I'm more interested in spraying from a roll, I'm not interested in the track much.
So, is that cam just fine for thatand how big of a shot can I go with from a roll?
I heard its better to have more exhaust duration than intake duration with nitrous.

Thanks.

Quickin,

Why are you even thinking about spraying? That ARE 436 should be devistate just about anything on the highway from a roll NA.

Spray is also a great way to blow stuff up if the tune isn't right and voids any warranty automatically.
