3500 plenum + boosted motor?

[Froggx]

I've seen things about the 3500 plenum helping top end on NA cars due to its larger size and shorter runners. I'm aware as well that plenum size is more irrelevant on a turbo motor. Would there be any point in going to the 3500 plenum on a turbo'd 3400?

Well, I got a good deal on one, So I will be trying it out. My 3400 will be supercharged though.

I went for the 3500 plenum, cause I liked the look of it and Also liked the fact that you can put a HUGE TB on it. 70mm

Will it help or hinder performance? I say we can sit here all day long and argue... but the facts will come soon enough. I hope to do back to back runs with both. So if you want rock solid evidence, wait about 5 months. :P

lol, 5 months is when I'm hoping to be finished with my car, so you can post your evidence then, I'll post mine, and hopefully they will agree, I figure for $90 why should I avoid it after all, hard facts are irrelevant

3500 Upper

I'm interested in trying this. Where is the cheapest place to get one from? I'd like to dyno with my current 3400 and then swap and see how this changes things.

Thanks,
Pat
