I talked to Rick at Extrude Hone and we can get another GB on these with 6 people. Let me know if you guys would be interested.
Here are the details:
Cost - $285 no matter what 2.5L UIM you send
Flow #s - 193 cfm (25% more than stock)
Here is a flow-data breakdown on our UIMs:
stock manifold = 155 CFU
single honed (98-98.5 SVT) = 170 CFU
double honed (99-00 SVT) = 180 CFU
triple (some people) = 188-190 CFU
This new process: 193 CFU, possibly bit more.
FYI -- our upper intake manifolds are the biggest flow restrictor in the engine's intake air path.
Let me know guys. I want to get mine done and I would like to get that low price. Thanks alot for any help getting there!
