What pulley size with these mods?

**rah575554eg** · 03-12-2010

I have a ported blower, ported LIM, ported throttle body, headers, TR8 NGK's, K&N air intake, high flow exhaust, 180* stat and Overkill PCM. I just wanna know what pulley would be fine to run with these mods? I want to run a 3.25" but I don't how well that would go over. Thanks!

You can run a 3.25" It just won't run very long. Go read the Safely Modding your 3800 thread. Then ask. I'd say a 3.4" but you never know until you scan it.

i wouldnt go 3.25 until intercooled...a 3.4 sounds good for yor setup though

I ran a 3.25" without methanol or an IC...actually a 3.0" for that matter until the injectors started to run static. Intercooler ISN'T required to run smaller pulleys

Right, I'm just talking about your intercooler quote. It wasn't correct...that's all.

yea just add some rockers to the list then id say run a 3.4, scan and tune and see if you have no knock. Then drop to the 3.25 and see what you can do.
