someone had posted some flow numbers a week or two ago and i can't remember who it was or find the post. but, what's the cfm ratings on our single barrel TBs? what is it on the 52(?)mm? anybody know what the stock intake and heads will flow? or what they are capable of with port work? tryin to get some ideas together here....

 

It was me. I posted in another forum about the 52mm being 300cfm's and the 62mm being about 430 cfm's.

To be exact-
52mm= 308 cfm
62mm= 435 cfm

Head specs- I have seen bench flow #'s from stock at 117cfm on the intake. 146 from a ported intake with stock 1.72 valve. All reports are that the intake side is what suffers because of the angle, and that a 1.8" intake valve would help greatly. The stock plenum on the MPFI also cuts the intake flow #'s down to 129 when installed and benchflow tested on the ported heads. This is why I built a custom plenum.

 

is the 52mm the one that we have stock?

 

Correct

 

hey everyone, well my cars engine was replaced a while ago with a 2.8 liter v6 and the guy who put it in didnt even kno what he was doing, he just wanted some money, and so he didnt hook up alot of the electrical so i just have little electrical things just hanging all over the engine and i have no idea what they go to, so if some1 would be nice enough to talk to me and like send me some diagrams or something that would be great thnx

 

rs1989, it would be more benifical to make a new topic then to reply to one. Also, since you just seem to be starting out on these, get a haynes manual or if you can afford it, order a helms manual. They are very useful.

Also, alot (not all) plugs only fit one part. Wont fit into others.

I also assume car is not running? If not, I wouldnt pay him a penny unless the agreement was he just swaps motors, and doesnt fix/finish the wiring.
