port and polishing heads/intake

[noslow5_0]

im thinking about gettin my windsor jr's and gt40 intake ported to try an get some power outta this motor before the power adder... think i could get at much as 40 more horses from porting and polishing this??? i know when i had the lower off the gasket was a lot bigger then the port opening.... i mean were talking about a good 3/8" difference all around....

I doubt u'll see 40 more like 15-25

Well technically you can port two ways. First is gasket matching were you just taper the opening to match the gasket. The other way is to port to match the gasket all the way down. If you do it the first way then I'd say about 15-20 horsies. If you port all the way down, I'd think you'd grab a few more.

u wont get 40...but porting IS the way to go

i think that 40hp on the motor and 30 to the wheels would be about right. the only thing is that----and if remember correctly---the gt40 intake cant be ported too much.

The Windsor Jr heads flow about 185cfm on the intake side - spend your money on porting the heads, the GT40 flows 205-210 cfm stock.

doesnt the GT40 flow as much as the cobra ?

i heard the GT40 flows a little bit better because of the tubular runners on the top ?

but it has the same lower as the cobra

In essence, they all flow the same. However, like anything else, each individual intake may be alittle better than another. I have a SF600 flow test of a GT40 and an Explorer, GT40 = 206cfm & Explorer = 209cfm.

yeah thats why im going cobra. GT40 IMO is kinda a waste of money

plus i think cobra looks better and something that was once on a explorer doesnt quite scream performance to me

you havent seen my polished explorer upper... its dam sexy... hahaha!!!! so 250 cfm huh tmoss??? how much power do you think that would yeild along with thumpers work??? think i could break 300 rwhp with the port work along with underdrives/electric fan???

[noslow5_0]

How much power you make depends on the WHOLE combination, and the cam and tune will play heavily into that. I can give you the potential for power in the intake, you have to do the rest. i.e. - some guys with my ported stock lower make 240RWHP and some make 260RWHP.
