Re: Throttle Body Discussion
I am new to the Typhoon game. Just picked one up and am still learning alot about these trucks. I know in the N/A game this would be an automatic upgrade to a larger and or ported throttle body for a small HP gain. With forced induction does a larger bore throttle body make that much more power or is it better to make the transition smoother with the air foil type mod, smoothing out flow into the throttle body just as good since it is forced induction?

Re: Throttle Body Discussion
What brand is that throttle body, and what is the cfm? If you don't mind me asking.

Tip in tuning on the monoblade is supposedly difficult.
I have one of these to eventually install onto my Pontiac intake.

Re: Throttle Body Discussion
its an ACCEL 74202S2 - ACCEL DFI 4150 Series Flange Billet Throttle Body. 1,550 cfm with a 4150 mounting flange...and you have to check throttle blade clearance.
$569.95

Re: Throttle Body Discussion
with that large of a cfm'd tb...i would imagine you'd need a slightly higher idle speed on our motors to avoid a tip in stumble. Was it mainly on easy starts from a dead stop that you found it to bog on you?

Re: Throttle Body Discussion
Part throttle (grandma driving) tip in stumble with the mono blade is tough to overcome from what I've seen even for the best tuner. For driveability, mine acts like a stocker for part throttle driving with the stock TB. Not sure how to calculate at what point our TB would be a limiting factor in a particular build with forced induction... Many variables to consider.

Re: Throttle Body Discussion
I have the Accel you listed. I found it to work just fine with a stock truck and the Ultimate chip after some messing with the IAC, TPS, and Idle settings using Datamaster to view the #'s to get it dialed in and work...It took some time to get it right and still had some "tip-in". It was excellent with Code59 and Tunerpro RT because you can make your own maps and it was seamless... no "tip-in" problems once I started tuning with Code59 they tuned right out.
I don't know if you would have an easy time finding an Accel. The one that RPM sells is nice and has the airfoil built into the front of it. Holley/NOS also makes a nice one that has a wet nitrous setup built into it called the "Body Shot" if you really want to go fast and end up on jackstands.:rotf:

Re: Throttle Body Discussion
just a stupid question...
if a 75mm throttle body will support 600hp
how much does the stock throttle body support ?
how much you planning to make mike ?
inquiring minds need to know :tup:

Re: Throttle Body Discussion
in a boosted app. on our trucks, i don't really think the throttlebody is the greatest let down.
sure you can pick up a few hp, and they look cool. and if you want everthing new, the upgrade is cheap.
but the air will be pushed. rather than sucked.
how far you wanna go?
first you need the heads flowing, than the exhaust and turbo size. than you can play with timing. and take some flaws out of it.
there is always a flaw
