plenum spacer/ t.b. spacer
 

yes i know this has been brought up many times. and nobody makes them for our car, so i am going to make a lower to upper plenum spacer plus throttle body spacers.i plan on doing dynoed resluts before and after. maybe i am waisting my time but i think somebody needs to try.dont hate...

do it up. couldnt hurt

I swear I just heard someone say they were making this for the 370Z.... Let me 'retrace' my conversations and see if I can remember who I was talking to...

I think the reason no one has made one is cuz its already been done at the factory. Ours is already spaced. I dont think it will do any good like it did on the 350Z, as Nissan made it bigger to begin with.

exactly - it doesn't exist because the very design makes it useless. The 03-06 DE's had a sloped intake manifold with a single throttle body entry. The spacer evened out the airflow distribution from the front to rear cylinders. This was addressed from the factory with the introduction of the HR in 2007 (and carried forward to the 370Z/G37)

ok, so i ordered in the material i am going to make them with, should be done in a couple weeks then off to the dyno...

you are still gonna make them when you know its already been taken care of? The throttle bodies might but the plenum wont get you anything I dont think, other wise they would have been out by now. Trust us all these things have been thought about by performance coompanies. But it will be an interesting build to see. good luck.

doesnt hurt to try if hes got the time and money i guess why not.

yes i am still going to make them and yes it might be a bust, but i am into it for minimal money and a little time. who knows just might show a gain???

Ill be curious to see the final results, post some pics and all.

Good for you for self innovation - in for pics a write up, good or bad or what ever

Props for experimentation. In for the results.

the material came in , now try to fab a template of the plenum and throttle bodies. kinda tough sicne everything is sealed with rubber o-rings.

Nice man, keep the updates coming... Ill test em for ya ;-)

Really glad you're doing this! Props for sure! Will be good to find out once and for all how the new 3.7 responds to this mod.

:tup:

thanks for the postive reinforcement!!:tup:

Definitely, man. The people who don't try are those that'll never move forward. If it's a failure, we'll all know once and for all. If it makes power, then you've done us all a service. Good luck.

Old thread, but any update?

lol, not yet as i have lots of work inthe shop. I am also trying to work on the rear mounted turbo... just not enough time in the day.

GL. Subscribed.

Motordyne has released their M370 upper manifold the 370Z and are having good gains with it :)

Kinda, but not really.

Can we keep the shameless plugs out of informative threads?

ok ok...long over due, but the plenum spacer and throttle body spacer are made. It looks very good overall. It was difficult being that I am utilizing factory nissan oring gaskets. I do this so if a replacement gasket is needed , its no harder than going down to your dealership. I will be on the dyno this week. I am using a 100% stock vehicle, going to be doing 3 pulls for an average on with and without spacers. No i will not be using a modded car as there is just to many options. I dont wanna post up pics until after the dyno testing.

Sweet, Good luck hope you show some gains!

Good luck, as always appreciate trying things that haven't been done on the z34 before.

I have seen and held these spacers, they are pretty awesome!

Nice! In for dyno!

Nice man looking forward to hearing the results. Price on producing this product for others?

in for the dyno lets do this!

Awesome cant wait for the results! Props to you jnaut for putting in all the time and work.

Nice!!!!

Are they going for production or its just one of item?

Send them to me so that i can test them with M370 manifold.
i will be running the N/A set up at the track for at lesat a nother month.
may get me into the 12.3's
How do you think the spacers will work on my stage 2 SC ?
Z

any Luck?

I was just researching this and wondering about it. Awesome that you're doing it... reps for that!

Bump for update

If I use (2) spacers will it double the hp gain versus just using (1) spacer?

How much will this improve my 1/4 mile ET and trap speed?

What happened to this thread..

IT died then came back to life I think the spacers probably didnt do squat but props to op for trying
