what yall think?

[el conquistador]

I've got an '97 OBS. I know i don't have a wastegate. I know i don't have an innercooler. I know the innercooler makes the air more dense and lowers EGT. etc...
My questions is, other than lowering EGT, What benefits do these do. I don't pull 20,000lbs regularly, I don't drag race or sled pull, which is better? A wastegated turbo, or what we got? A "non-wastegated turbo"? Just curious. never have had this question answered.
I always thought about getting an innercooler, which, i suppose, means i would need a wastegated turbo. Until Obama sends me my new stimilus check, that ain't happenin.
Don't get me wrong, truck runs great, but wonder if there is that much difference. do you need a wastegated turbo for the innercooler? WHY?
Thanks, just wanted some professional, real world advice.

Still running my stock turbo with the intercooler installed.

Don't worry about the wastegated turbo... get an I/C on there or water injection

the only purpose for the intercooler is for cooler exhaust temps , its not that big a deal really if you arent pulling ,racing ,etc. to need to worry about egt's , if its chipped and you are trying to get full potential then cooler egts do help with power some , but still no drastic differences, as far as wastegated or not that doesnt matter with or without intercooler

i appreciate the info. i have always wondered about it. I'd like to get an innercooler, but man, they are high!! i'd like to retrofit a 6.0, but again, HIGH!! I kinda like not having the cooler tubes cluttering up my engine bay anyhow. It's bad enough already.

I put an EGT gauge on my truck 6 months ago and it's after the turbo an pulling a hill the other day with 10,000lb, the EGT's wanted to go to about 1450!! So i let up on it. But i've got an Edge evolution and had it at 60 extra hp, and they say that it's safe for pulling without a gauge. Kinda makes me wonder how high they got the other times when i was cramming it up the same hill, pulling a load without the gauge!!

of course, Edge probably really only says that because the SD have an innercooler and "should" have no problem.
thanks for the replies guys.

1450 is bad.
(PS dump the edge!)

never listen to a company say its safe to put any type of performance upgrade on a diesel engine with gauges.... thats just rediculous...

first thing you have to do is get yourself a full set of gauges

second is take that edge off and get a custom tuned chip... TW or dp

then the IC kit...
