just throwing it out there.. i havent heard anything about this.. anyone have an opinion? is it better than a spacer? will it fit under a strut bar? what about this with a spacer? just some ideas.

 

It is a great plenum. Very light weight, strong, and a good alternative to a spacer but it has been discontuined so that listing might be out of date.

 

i was looking at the tallboy at one point, know why it was discontinued?

 

don't do a tallboy + spacer, it's too much plenum volume. A spacer or tallboy is enough. I don't think the tallboy fits under a spacer, I could be wrong though.

 

a friend as it and loves it. It well not fit under a strut bar nor the engine cover

 

its been around for years... there were several: Crawford, Kinetix, APS + 1 or 2 others... basically plenum spacers have all but done away with the high plenums.

SportZ magazine (now Nissan Sport) did a plenum shootout a couple/few years back... the spacer was as good (actually better) than any of the plenums.

If you can find the article it will show you the dynos... I have the mag, but not going to take the time to dig it out and scan the article... you can PM DaveO - if he's feeling generous he might send you the data.

Bottom line is there is a reason you see so much about plenum spacers these days and not "tall plenums"... its because the facts were made clear a couple years ago (not just the plenum shootout article – many independent dynos, butt dynos and track results).

Happy modding.

 

Spacer will be cheaper and allow you to put a strut bar or engine cover on with it.

 

This might be a stupid question, but will this tallboy fit on my 08 G35? I have from my 350z which I traded in...
