HP support on a 5.0 Cobra intake

Anyone know how many cfm's a ffrp cobra intake flows?? Or how much horsepower it will support... Running 331 stroker with flowtech heads, bbk short tubes, cat-less h pipe, TFS1 cam, 42# injectors,calibrated MAF sensor,all MSD ignition with 6a box,255 fuel pump,bbk CAI,balancer ect. I'm wondering about how much more power I could make using a better intake

You could either get a new intake which would allow for more top end flow or you could get your cobra intake ported which if done well will match any new intake. Also remember all flow benches are not made equal just as dynos aren't

The Gt40/exploder/cobra intake flows 200 cfm in stock form and 240-250 when ported fully.

So fully ported it will flow a bit less than some of the intakes out there (trick flow)

Yeah but flow isn't everything. The Cobra ported is going to do better than anything else as far as street manners, low end etc... To a point obviously. If you've got a worked stroker you'll need the cfm to support it.

Check T Moss porting, he's got a wealth of knowledge and has years experience porting all the variants of the GT40's. he also has the stock and ported flow numbers posted on his site.

Where is he located?? I'm down in Alabama. Would need pretty quick turn around, and what does he charge ??

---------- Post added at 05:26 PM ---------- Previous post was at 05:22 PM ----------

Just wondering cause my car makes around 410 RWHP and was thinking that my intake is holding it back from the potential 450 hp I'm looking for. I do not race this car, I just play around and cruise it but, I do like to spank the occasional New car that's next to me.

I can't remember right off hand, maybe Scotty does. I'll try and look it up and post for you. As far as turnaround time, I'm sure if you call they may be able to work with you.

I had mine done in the mid 2000s so prices will probably not be accurate. IIRC it was $150-$250 for the lower fully ported. The upper already flows 250 cfm so any porting there is pointless.

thats gasket matching, a full port is much more intensive, hell gasket matching is easy, porting is an art

Send it to Tmoss. The only negative I had with the whole deal was the damn thing was so nice I wanted to mount it on the wall in my man cave lol. Yes the exploder intake is perfect to send off to have done. That is actually what I did to avoid down time. I bought a $100 1st generation exploder lower on the evilbays, sent it to tmoss and then just swapped them, only took a few hours.

Here it is atop the mega budget motor I built. You are looking at a sub $3k complete rebuild right thurr lol.





Thing made 301/325 to the wheels and that was with terrible old injectors and the MAC longtubes not matching up with the exhaust ports correctly. Probably had another 20whp in it at least. Was a fun car.

All I've heard is good things about Tmoss and how quick their turn around time is.

They also straighten the ports.

Scotty, 301/325 off a budget build is awesome! Im looking to do the same thing. I just sent an e mail to Tmoss myself to have my explorer intake done.

Yeah it was a self hone low mileage block, stock rods/crank KB116 dome pistons, used edel rpm heads, tmoss intake, used comp xe270hr-112, used 1.7s, I already had all the "bolt ons" and tune was done by radical in atco,nj. In hindsight I really should have just found a low mileage short block, swapped my Cobra hci over and just supercharged it... oh well live and learn. That was back in 2006.

I hear ya! Since I had one car HCI and one forced induction.... I think supercharged wins every time! I think that's my plan.... Freshen up a decent bottom end, throw on my fresh GT40p's with my Tmoss explorer intake, add in a decent cam (undecided which) with 1.7's, and either a V3 vortec, or procharger.

---------- Post added at 04:12 PM ---------- Previous post was at 04:10 PM ----------

Krazy horse, they've only gone up about $20 on the porting since Scotty had his done. $160-170 for a good port job is definitely worth it!

**** $160 for a tmoss port is TOTALLY worth it. You can find a complete explorer intake for $150 if you look. That's a $350 intake with shipping factored in that'll flow like the aftermarket ones and have way better low end/street manners.

As for the cam with the GT40 heads/tmoss intake and a supercharger... Stock GT cam. Great blower cam, free, stock street manners, stock gas mileage if you keep your foot out of it.

I'm at around 9k in the total build on the car body I bought for 400, had to change everything under the car including floor pans. Doing all work myself so saving lots of money, only issue is time, one say a week if I'm lucky to work on it
