Lower intake
 

Has anybody done a port and polish or extrude hone on a lower intake? If so what type of gains did you receive.

Synolimit. Megan370z.

Thanks I will check them out.

Just got back my lower intake and installed it. It made a big difference in my engine response. Im getting on the dyno sept.3rd to see if it gave me any gains.

Finished product.

Do you have the Z1 plenum? I was thinking about doing this also

Will be interested in what happens with this also, I just installed my M370 and felt a NICE difference in the car and Z1 HFC's just went in 2 hrs ago. Looking to finish off my NA build

Looks great, I wonder if there is any merit in doing this on a boosted application. I doubt the gains would be as great.

I have an extra one for sale if somebody would like to do this but doesn't want their car down for lead time.

Yes I have the Z1 plenum and bored throttle bodies. The motor was very responsive before but after the lower intake got gasket matched and extrude honed it took it to another level. Getting retuned September 3rd.

Not any more!:tiphat:

Just got dynoed and my car out down 340 whp and 265ft tq. I think the lower intake mod was worth the money. I will post the sheet sometime this week.

Holy cow that is great numbers!! What mods do u have on ur Z?

Can you please tell me who did the work as well as the cost. Thanks

Extrude Hone in California. I sent them the gaskets and the intake and they did the rest. It cost me 600 dollars. I know that's expensive but it's another step done next is a stroker kit.
