HPI Throttle Body
I'm seeking some info on there HPI intakes and have a question about there latest offering...
its where they offer a 55mm T/B with a 58mm manifold attached to it...vs. the 58mm work of art they have available...
I'm getting all my information together for the 120R crate I plan on getting soon and was curious as the how well this unit performed?
Talking to the rep he mentioned that the 55mm-58mm would allow much more torq down low and in the mid range and with the 58mm it would have more torq at the top and not do near as well in the low end torq area...
with this said from what I have seen the 120R doesn't seem to be inadiquite in the bottom end when we speak torq...
Anybody got any views on this one and/or used it and can show a dyno sheet by chance...
Thanks

Have fun!
Much more torque down low? i have no idea.If you went with a milder cam(cyclerama 575 or a tman 590),i could see using the smaller bore.you could always use a 31 tooth pulley for a little extra down low.............
