Thread: Nitrous Guys Step In!!

Any one else running nos that would like to add anything??

Neither GT's or GTP's come with forged pistons... it'd be awesome, but the only difference between the two types are bowl depth and connecting rod length for compression difference. Dropping from 9.4:1 to 8.5:1 was GM's only bottom-end change to fend off trouble.

If they were forged, alot of replaced engines wouldn't have been bought over the years due to issues like these...





And here's what a forged piston looks like when it fails...





The top doesn't fail like our stock ones do, it takes an extreme amount of leaning out to cause the failure, unlike the failures that even a moderately knocking 3.4" pulley setup can do to a stock motor.

Our connecting rods did improve with the Series 3 introduction, though. That's a proven fact that I've inspected myself on multiple builds (all '04+ supercharged cars, even Series 2's... and then they did it for all '05+ N/A 3800's).

On the topic of nitrous though, I'll be reading more from those doing it, since a local guy will be swapping his setup from the L36 he had, to the L67 he now runs. A handful of locals are thinking about it in the distant future, including myself on my forged RWD setup, so I'll be paying close attention to the tuning results.
