Free port and polish on your 287 lower collector intake runners if you can get it pre/post tested on the dyno.

And rather than you sending out your collector for it to be worked on and leaving you without a ride for several days, I'll make it easy. I'll send you a new brand new ported collecter and you can send me your old collector after you are finished switching it out.

The polished collector must be installed while on the dyno (or at least while at the shop) to directly measure its effects. Coolant temperatures must be monitored via OBDII scanner and controlled to 190'F for all runs.
Same day. Same dyno. Same tank of gas. ECU resets for each set of pulls.
Dyno data must be exportable in electronic format.

Pre/Post results will be analyzed and posted here on 350Z. You can also freely post your results.

If you want, you could do the pre/post testing with a plenum spacer but the "pre" testing would also have to include the spacer. With or without a spacer, the test objective is to focus on how the port and polish changes the dyno results.

The spacer isn't free but I can give you the GB price on it. Give me a PM if interested and let me know your mod list.

What kind of dyno? I'm interested. Email geoffbrown@comcast.net. Is this the lower part which goes into the heads or the middle runner part? What if the P&P makes less, can I keep my old one and send you back the ported one? Just put my car back to stock, so it would provide a good baseline.

 

Any kind of dyno will do as long as its reasonably repeatable. This would not be the "intake manifold" which bolts onto the heads. This is the lower collector or middle runners or what many call the lower plenum.

And yes, if it made less power you could simply return it.

I could do it on a dynojet dyno. I already have a 5/16th spacer.

 

I am down! Details

 

OK. Three should be enough.
Lets do it.

 

i have a lower intake manifold right now sitting in my living room that i am almost done porting and polishing, i am also direct porting nitrous into it, i plan on dynoing before and after, or at least get it on a flow bench next to my stock one first....

should be done by the beginning of next week

 

Awesome.
Lets see what this stuff can do.

 

What is a port and polish dyno tester??

 

It's the 3 people that answered before you....hahaha. But most importantly, it's not you.

 

if you need anyone else to test it, i'll do it im in so cal as well and have a good place that is also @ sea level

 

if you need any one with fi to see how that goes let me now im local.

 

Tony,
I am game here on the east coast (NJ) is you need any help also. Only mod I have now are a z-tube and K&N. Your spacer is on the way to me this week, I will have dyno time next monday and tuesday.
