Hello,

i'm wondering what kind of gains people have gotten with a 70mm tapered throttle body (like SOS) vs a 70mm straight throttle body (like skunk2)

SOS has dyno charts proving up to +12whp peak on 6-7psi boost. has any1 dynoed before and after for a 70mm straight throttle body (and port matched IM) on a supercharged setup?

it makes sense that it might be more.. but some people have said otherwise and i can't find any solid results.

I just bought a skunk2 alpha for my car. Unfortunatly i will not be doing a back to back test. I am interested to hear if the alpha 70mm will even work on a S2000 intake manifold. I might be the first test dummy for this...

I thought the alpha was a tapperd tb, not straight through...

i believe its a straight bore 70mm

some people argue the venturi effect in favour of the tapered tb.

I'd like to see some hard evidence.

wish you were doing a back to back test... do you know what you would put down on a dyno now? for rough comparisons sake?

I was actually looking at this for the past few days. I am looking into Maxbore and getting the TB and IM done once im done with my turbo build.

fullblown 74mm port matched ftw!

I have been thinking about a throttle body lately for my Ptuning ap1 on pump/meth since its on a 3076 and i am trying to squeeze every hp out of the "small" turbo. The full blown 74 looks like a great piece dont get me wrong but is it really THAT much better than a skunk2 alpha for a thrid the price???

Full Blown Motorsports, you get a straight and tapered option just by swapping out a spacer, and its pretty.

I'd take Fullblown over Skunk2 any day of the week.

Do they have the full blown one for ap2?

What kind of gains can be seen from the full blown one? Does having a larger tb hurt anything ?
