The statement "Theres no replacement for displacement" is faily accurate.... A modern fuel injected V-8 that puts out 280 HP will run better than a Turbo 4 or 6... with 280 HP. No Turbo lag and you dont have to wait for the engine to rev to 6500 rpm to make any power.....

Oh man, I had a '68 340 GTS.

That car was the greatest sleeper. Blew away more than my share of mid-eightes Z-28's and 5.0's that thought they were racing a granny mobile.But my buddy had a near stock 69 340 Dart...

civics are fast, actually i've seen civic beat a 10 second camaro on more than one occasion
Did you all forget about nitrous. I have respect for any car that can hang with an import 4cyl. running with NOS.
Yes, there was. I figure it's like 4-wheeler or MXA flame threads. Every six months or so you see a new one pop up.Wasn't there a "rice-burner/rice-rocket" flame a few months ago?

A turbocharger rotates 8 to 12 times greater than engine RPM. A typical Roots or Paxton supercharger rotates 2 to 3 times greater than engine RPM. The turbo is also exposed to exhaust temperatures as well as compressing air and operates at higher temperature than a blower. The oil lubricates and carries heat away from the bearings. When the typical turbocharged engine is shut down oil no longer flows through the bearings. The oil that remains is literally "cooked" to the bearings. In the application we were running, a VW "pancake" 4 cylinder engine, we'd shut down the engine at the end of the run. After five or six hard runs the bearing would sieze and the turbo wouldn't work. Sometimes this happened in the middle of a run. :eek: The solution would have been to run a "soak back" pump that continued to feed oil to the turbo bearings after engine shut down. Instead we yanked off the turbo and dropped back into the "naturally aspirated" classes.Originally posted by Rockrider300
... is that true about the turbocharger problem. Do the superchargers have some of the same problems.
Had forged pistons and 12 degrees initial advance... but 35 degrees total advance. Still ran in the mid-12's with three "bad" pistons though. :confused:Originally posted by KXKen
I believe that forged pistons and some retard on the ignition timing could have saved this one.

KXKen - You're right. I didn't build and set-up the engine to run on nitrous. I added the system later on to drop my ET into the low 12's. I dialed the system in per the NOS instructions. However I should have had the distributor "professionally" re-curved. The funny thing is the motor still ran fairly good. I'm not sure when the pistons melted or how long they were ran that way. At the time, that car was also my daily driver. You and I actually agree though. Nitrous set-up is very critical. Many people (including me back then) think it's just a matter of bolting up a kit. In reality it's more like trying to dial-in the carburetor jetting on your dirt bike..
If you read the owners manual for a turbocharged vehicle, they tell you to let the engine idle for a short period BEFORE shutting the engine down.

KLX - That is why there are fewer turbocharged passenger cars being sold today than 15 to 20 years ago, at least from Chrysler, Ford and GM.It was rare to find a customer that actually let the car idle before shutdown anyway, most people couldn't be bothered with the delay.
