If your going to port it use a dremel but but go easy the plastic will heat up, Then go over it by hand with sand paper. You know I have a ported M370 and a non ported M370 I would sell . possibly the Z1 also

 

Yeah I noticed one of your listings. I thought about buying the z1, but would rather spend the money on sway bars at this point in time. Maybe down the road when I decide to port / polish Tbs and lower plenum...

BTW what would one expect to pay to port/polish throttle bodys and lower plenum?

Thanks

 

Its about $200

 

My other lower has been delivered to Scott for porting on Friday

 

Got the lower from Scott and man it looks great! Installed yesterday and should have some driving notes this week. No dyno this weekend, Will have to be on the 13th. ;/

 

That looks great! Do you have any idea of how much material was taken off?

 

Idk if I'm aloud to say here cause I'm not a vender (all transactions were done on another forum admins) but I removed an *** load! His two halves with the casting marks were crazy off! Along with 100% removal of both bumps in each runner it was quite a lot. I could of removed more however but without the heads and upper it's hard to do or I could remove to much and cause a lip at the heads. Also you don't want to remove to much in the middle, which you could, because you'll have a small opening coming off the upper mani, have it open real big, then neck back down going into the heads. I'm not sure an hour glass shape would help flow.

 

Any update?

 

Oh wow man sorry guys was updating another one , Car made great power 302 WHP and 240 WHTRQ( Heart breaker) dyno, Also ran 13.5 @105 MPH at the track. I switched software also to ECUTEK.

 

What are the chances you know of a diy to swap the lower out? I've looked everywhere!

HELP!
