Taken from the ITB thread

Has anyone actually tried this? Hondata IMG + Larger Bore TB + Velocity Stack? What kind of tuning/EMS would be required for this? How safe would this be without tuning? What about heatsoak? Am I smoking crack?

 

Try it, I run a velocity stack on the end of my custom intake. but I have not tested what the effects of just the VS are.

I think if someone is going to go out and say the VS is better than XX intake, they had better have proof......

 

Is yours similar to the PRM?

 

I am actually using the PRM filter and velocity stack..... the Stack is very very cheap and flimsy...... I am working on getting a nice polished on or having the one i have painted

 

so then an open throttle body with a Velocity stack and NO filter would make the most power vs any possible intake setup?

 

says one person, no dyno sheets or evidence to back it up. I dyno'd my car once with nothing, just the Throttle body. no intake or Velocity stack, and the car made like -13 WHP vs having the stock intake....... I can not see a VS making that big of impact.....

 

In a couple of the older threads Ultimate Lurker was commenting on how with header and exhaust modifications he found the F20c to be "starving for air". He commented on the TB and plenum both to be too small.

I don't know enough to comment on whether one should be small and one large, I thought you want to eliminate any restriction.

I have also searched a jillion bolt on threads and I found one curious. I can not remember the thread, but one guy was posting dyno plots on his car from a dynojet with your average I/H/E mods and was consistantly several horsepower more than most people. (I know, I know, different dynos, different conditions) but the one extra thing he had was a spoon TB. I am sure any bored TB would do. But it makes me wonder if a bored TB would make that much difference on an NA car.

Msst FI guys say it won't but that old thread and UL seemed to give reason to think otherwise. Is he still posting on the board?

If ITB's can make power over stock by letting in more air, I don't know why changing TB and intake manifold could yield results somehow.

Anywho.....too bad there are no alternatives for intake manifolds to choose from. Only that carbon fiber one that looks kind of nasty.

IIRC that thing has some kind of issue clearing the hood?
