I don't know anyone with this manifold and running it with the twin dual throttle body opening. Everyone sticks to the 75mm, although I heard their is no difference in hp between the 2, i don't mind because it looks naaaiice!! I bought a 2001 bullitt jlt ram air kit, bbk 62mm dual throttle body, bullitt cruise control cable and throttle cable to make it fit. Yeah I spent a little extra money, but I can always sell what I have to make up for it. I will put it in next week during my spring break and I will have it dynoed sometime in May.

i hope you plan to rev over 7500 because they dont make power till you are over that

but it does look good

Yea, any tuner I've talked to said these intakes in general like to rev high on an NA motor, especially the oval TB style manifold.

Yeah i did my share of research. I dont expect much not, but in a few months i will get the tfs heads with a cms stage 2.5 cam and rev it high (i have a forged bottom end) so ill see what it can do

Im glad your doing that, i've been wanting to see a 2v revved higher for a longgg time, i bet they will do good.

yeah man, I been tempted to go forced induction, but I like to be able to say that I have a fast n/a car. A guy on the other forums has a carb 2v with 12.1 compression and he dynoed at 425hp with these heads (previously 384hp with fully ported stage 3 pi heads) and he revs all the way to 8000 rpm. I've read of others revving to 8500. I know it won't be too streetable but I also don't drive my car daily anymore so what the heck.
