Blower porting

[FirstOnRaceDay.]

what are the hp gains vs dollars spent on getting the stock m112 blower ported? i'm going from a fairly stock 96 cobra to the c head an eaton swap so the difference in power will already be noticable to say the least. i've seen the large keyhole cutouts on the bottom of some blowers, this seemed like that most cost effective way of going about it

should i just get the keyhole cut out of the bottom? porting the inter, tb, plenum and lower intake seems to yeild very little hp gains for what i hear people spending on their port.

tell me what you think


i'm not trying to pay for a $800 for 10 more horse power at the wheel you know what i mean.

keyhole port and pully the hell out of it?

Send it to a pro (Posi) and get 60+ hp depending on mods/pulley. A port is probably the most efficient $/hp mod you can get.

how much hp would the large keyhole housing port yeild? it would be something like $50 vs $500-800

If you want the port cheap and are capable of doing the work, look under posi post's, Hey has a DIY eaton porting thread.

Correct me if I'm wrong but isn't the inlet the one that is responsible for the majority of the hp?
