CAT

It always makes me laugh when guys are so quick to point out that the parts for cat are more expensive. How many parts are you constantly throwing at your engine that this would be a deal breaker. You must be doing some pretty wicked stuff if you engine parts are factoring into your daily costs.

 

I think to run a single the IVA's have to be disabled, and the compression ratio is too high without them cracking the intake valves open.

 

Why would the IVAs have to be disabled

 

Too much back pressure in the intake.

 

Water pump, compressor, way more for a cat verses a detroit.
All engines that vintage are coming up on rebuild time, and the costs of an inframe, Cat verses detroit, are vastly different.
I wasnt dumping on cat, i liked my c15, pulled like a freight train, was a great engine. No need to get defensive, just pointing out the facts.

 

It's not defensive, to each their own. It's your money and business to do with as you please. It's just the first thing guys like to point out.....every one. Even if it is up for a rebuild, that's once every 8-10 years or so. The added cost isn't going to break you. Again, not even a factor. Get what pleases you. If the extra $2k is the deciding factor.....thats pretty sad.

 

I suppose that is possible . But for arguments sake, isn't back pressure in the intake just boost pressure really. There's always pressure in the intake. I dunno, just curious. Yours is the first answer I've ever got to that question

 

The high boost pressure that accerts are known for is a false reading. Some of that pressure is a result of the compression in the intake because of the IVA's. It takes two turbo's to overcome that back pressure and still force the air into the cylinders.

 

Nice try, but not accurate at all. Do some research on the miller cycle, that is basically what an accert is.

 

So explain it to us.
