Already shift at 7750 for 36,000 miles and 180 passes so no changes for me until I upgrade the springs

Over the boss?

Yes look around...Boss cars hover in the 420-430 range and CJ intake cars are 450-490 depending on fuel and throttle body and cai choice

I knew this mod had to have some merit.

Yeah, that's what I was wondering. I didn't remember you doing any valve train upgrades, but just asking anyways. It's going to be sweet.

Cant wait Derek!





Awww Nic...when I get rich I'll be your rich uncle in law three times removed

Haven't had the plenum in our hands yet (or one on our dyno), what's the reported torque losses coming out to?

From what I think I remember seeing on SVTP, TQ losses are around the same as the Boss....I'll have to go back and find it....but I don't feel like it. :lol:

Damn you, D!

I'm assuming torque losses beyond that of a BOSS? Basically an overgrown BOSS that picks up peak but drops TQ only more in both directions?

Pretty much. There is no way it makes the power that Brent thinks it does. 50hp over what a Boss does? He's trying to say people are picking up 70hp with just an intake change in a NA platform. LOL, no way.

Only a turbo car will truly be able to benefit from the CJ intake.

From what I understood, the intake only really picked up more power when spinning to the motor up to the 8100 mark like the CJ motor...which obviously can't be done on a stock GT.

Yeah I was going to say that but I didn't want to start shit cause I know how sensitive people are when I disagree with them.

All the cars that have this intake are in the 450-490 range SAE with full boltons some with e85 some with 91/93. You pickup HP and TQ across the board and lose no more TQ than what the Boss already lost. The key is NOT the intake but rather the throttle body choice and the cold air tube and MAF...I chose the largest of both ;)

I'm interested in seeing your results. That kind of power with bolt ons and a stock longblock would be impressive. The problem with it is having to rev the hell out of the stock valvetrain. In a couple more years I bet we start seeing a lot of cars running the Boss intakes spinning them in the upper 7k range starting to have valve/springs issues.
