1. Type the @ then tmoss. It will pop up his used name and tag him (or his son.)Well fellas based on what I am getting so far I am leaning heavily toward a tmoss ported lower cobra intake for my application. I really like keeping a car close to stock appearance and that cobra intake on top under the hood looks great to me. I have a dyno sheet on my current setup. I will try and find a way to contact Tmoss and when it is all done I will have another dyno done and we will see what we got. I appreciate all of your input!
Helpful.Just to add on to what I said earlier. I found the video I was talking about. I’ll spare you from watching all 30 mins.
Long story short. AL headed 302 with a GT40 intake vs system max. Just like I mentioned earlier. The long runner intakes make more power down low, but at 4750 they switch and the Holley takes off.
Gt40 in blue, Holley in red. Gt40 just runs out of steam around 5k rpm
Just for giggles. AL headed 302 with stock HO intake and edelbrock intake. As you can see, the HO intake even outperforms (not by much) the RPM II at low rpm, although the crossover point is much lower at 4000 rpm
GT40 family intake dyno tests
To sum it up:
1-2 HP differences between GT40 tubular and 93 cobra. 94-95 cobra was 5-6 HP less and explorer intake was down about 10HP from the GT40/93cobra. I know some publications out there claim there is no difference between the family, but i've seen enough evidence to convince me that the explorer upper will cost you a few ponies as compared to the tubular/93 upper.
All were run on an unported lower manifold. SOme of the comments asked for doing it with a Tmoss/Bigdogs ported lower. Richard has some other videos wherre he compares the GT40 family intake to aftermarket. The aftermarket intake makes more power, but at higher RPM (over 4500RPM or so) while the GT40 family intake made more power at lower RPM. So really selecting between the two comes down to if you want higher PEAK power at higher RPM (great for racing) or more power at a lower RPM (great for street driven cars).
I have Seen a lot of banter between big dogs and t moss . I wonder what the reality is. Miss’s have done it forever . He did my systemax for me .
I have seen big dogs claim they outflow anything that moss has . I’d like to see an unbiased party test it
Did the article/video run the Edelbrock RPM intake? Any other product with this name is a safe choice for a wide and useable power band. Engine Masters on MT ran the episode that tested carbed, dual plane intakes with an AL headed 351 again this morning.
I would like to also see what the ported lower GT-40 family intakes would have done in the same test.
