This definitely looks like something that could be DIY'ed.

Ya seriously thinking about saving myself 295$ lol the one that would be a pain is z1s lower plenum port the aluminum runners they offer that for 300$

The_Assassin

Where did you see that lower plenum port for 300$

rugbyforlife

You have to message or call z1 and aske for it but I heard about it from a guy doin it to his g37 and they offer it for the 350 as well

The_Assassin

did it make power?

The_Assassin

Guys I called z1 about gaskets and they said I won't need any. But my mechanic says I will. I cant seem to find throttle body gaskets for the hr. I found the plenum gasket on their website tho.

The gaskets are all oring style and reusable, you will be fine.

The guy I was talking to that did it on his g37 made 338 whp so it must have helped lol

The_Assassin

so this mechanic messed me up. I could have gotten tuned tomorrow. I guess he doesn't work on Zs all the time. I will go back to his shop today.

Not bad numbers lol. You ever ran him? what mods?

does anyone know if this mod requires a tune to run yet?

Just spoke with Z1, this mod will is NOT a tune ONLY required mod. You can run it like any other bolt on, gains will be made, but obviously you want to tune for MAX potential

The_Assassin

yea its just a bolt on mod. You will get gains but to get max benefit you will need a tune.

rugbyforlife

No he's a couple states away. I prolly wouldn't stand a chance! lol his list was a mile long! Lol

The_Assassin

Just got back from my mechanic guys it took him and his guys around 25 mins to put it on. Immediately after removing the stock plenum they compared it and was like" damn, thats definitely bigger" they all seem to think it was a good port job.

Getting a tune next saturday and I will report back with the results. Both on pros tuning mustang dyno and my local dyno jet that I did my baseline last year. If it works out well I might get z1's lower ported plenum also.


lol oh I see.

Any updates?

The_Assassin

In my opinion it works well. Mechanic was impressed with porting job. I got a retune after and went from 270 to 295 on a mustang dyno. The majority of those gains might be from the retune but the only part that was added was the ported plenum. Am guess maybe 10 whp from the port job. I already contacted z1 about getting the lower plenum from them also. I just bought diff mounts and some other stuff so in january or so i will purchase it from them. PreviouslyI was at 301 whp on dyno just before tune.

Just curious what power mods do you have?

The_Assassin

Top speed pro 1 test pipe, stillen y pipe, injen cai, z1 upper plenum, agency power single,, on that same dyno now that i made 301 a while back i shpuld be at arpund 315whp...you can look up my car on youtube if u like or view my thread

Good mod list man, I would ditch that stillen y pipe though. I've seen it lose power on about 6 diff set ups...../ gains when switched out to HR Y or xyz
