This.. Seeing as how my motor coming together slowly(WAY TO SLOWLY) is getting a s trim, I'm not so much worried about high rpm hp. Just want to make sure I can hit the tires off the line. To the OP, both TMOSS and fox lake both do porting on your lower. Fox lake's is much more intensive if you want it to be(involving welding, etc..), but people love TMOSS ported lowers. IIRC, TMOSS charges about $150 to port the lower. Worth giving a shot and seeing if you like it before you go all out and buy a new intake. If you don't like it, I'll buy it. I still haven't sent out my gt40 lower yet.
Come on guys, we all know it's not dyno numbers OR track times that matter. Ignorance is bliss. THINKING you know everything is enough to make most people happy. Soooo, you're running a centrifugal supercharger and don't care about high rpm power... That makes less sense than putting a gt40 on a 351. High rpm is how that kind of blower works. I wouldn't spend $150 to buy a gt40 intake, nevermind waste on porting the junk.
Wow, this thread turned into a pissing match real quick. I like how EVERYBODY has a chip on their shoulder over someone else's motor. In comparison to a roots or twin screw, yes. But a centri can be made to work on a low-revving street motor in the same way a turbo can- by sizing the supercharger, spinning it at the right speed, and matching the right components together. Its not a stretch either, otherwise Paxton, Vortech, etc wouldn't offer them for stock motor 302s. Anyway, I think the GT-40 intake argument is starting to be pretty compelling right now. At first I was against it, but now I'm curious to see what a fully ported unit could do on a 357.
Ahh, I've been looking for something like that for a LONG time! Look at that, the Explorer hangs right in there with the other two manifolds. We need to save that for all the Explorer nay-sayers. If anything, the tubular manifold seems to flow a little less than the cast manifolds.
I knew someone would appreciated it, especially with how many Explorer intake threads I see floating about on Stangnet. The aluminum uppers allow someone to extrude hone them (hopefully the lower as well) where as the GT40 is limited by the "tubes." 9 times out of 10...extrude honed parts beat ported parts...heads, intake manifolds, you name it. Here's a cobra intake combo Cobra Updates Marc Arnold's follow up about extrude honing and the hp gainged... extrude hone - SVTPerformance "I had my intake Extrude Honed back in 1999 with this combo: http://www.andersonfordmotorsport.co...rnold-302.html "We saw about 8 rwhp on my car. Worth it is a relative term. At the time I was trying to eek out every last n/a hp from my combo with the stock shortblock and still keeping emissons compliance. To me, it was worth it to keep the stock look. It was very expensive though, around $475 if memory serves." Even Marc recommended t-moss.

Getting the most out of a car and having something that satisfies you are two 100% totally different things. The guy looking for the most won't be running that intake on a stroker 351. The guy who wants to have a car he enjoys, likes the look of the intake and already owns one... he would run it.
OK Cats, here's the deal... MM&FF 1997 tech guide shows the difference between a tubular GT-40 non-ported lower and ported (extrude honed) lower in flow numbers. Stock lower flows up to 215 cfm Extrude honed lower 295 cfm Total intake upper and lower run on flow bench stock flowed a total of 238 cfm Ported lower flowed a total of 271 They did not lose any low-end grunt and gained all around by doing this mod.
