Which smooth metal pipe is better for our engines in the long/short run?

Bonnevilles are restricted to air flow due to the radiator. We need to find out which pipe will help the car perform better! The long Pipe made for a Civic, etc. or the short Pipe made for 4 GM cars including Bonneville. Let us know what you have and how it has perfected performance! Thanks! Vote! and let us know what YOU think!

Short RAM needs a heat shield or true CAI setup to be effective, the longer RAM gets colder air already, but I would think you should keep the MAF screen in if you have longer RAM pipe to ensure laminar flow.

So..wouldnt both have there pros and cons?

I think both of us removed the maf screen and no problems. I can say it feels better for me. My maf screen was dented and messed up allready. I will try to get a pic of it up soon.

This is what I was talking about...

I've tried both the short pipe arraingement and the long pipe (I had each set up in there for about two weeks). Didn't have either set up as a true CAI. I haven't found either one to be any better than stock. This is by both seat of the pants feel and G-Tech data.

Reset the PCM in both cases and ran each for about two weeks. Still saw 135-140 HP best case on the G-Tech with the long pipe. I popped the stock intake back in last night and immediately saw 170HP. Seat of the pants feel was there also. G-Tech may not be the most accurate device, but it seems to follow what my seat of the pants feel tells me.

It was mentioned to me that perhaps a low restriction exhaust or 2.5" pipe might improve the response. Haven't had a chance to look into those yet.

Just my two cents.

The best setup would FWI, followed by CAI, followed by intake tubes, and finally stock airbox.

Both would have laminar flow.. flow gets distorted from bends and cinks in the tubing or stock accordian tube.. the length would affect the speed the air goes thru. from start to TB. That part I do not if longer is better. You will always need a heatshield IMO as even with the long pipe, you're still going to get heat as it radiates from the rad and motor.. the only time you don't need heat shield is if you're running FWI. If you want to go a lil more extreme you can also wrap your pipe up

I was wondering if the placement of my IAT sensor may be more critical than I thought. It was mounted in the rubber coupler between the pipe and the TB on the short pipe and I kept it there when using the long pipe out of convenience.

Do you think there would be a significant difference if I mounted it either in the pipe closer to the filter or in the back of the filter? Would it be noticeable if I moved it without also installing a good heatshield?

I think it would as it senses the tempreture of the air going in.. and having it close the the TB it would be subjected to more heat thus the computer would think the external air temp is hotter then it is. Running a leaner setting.
