to add this mod with jl ram air kit , do you have to have a performance chip ? or can i use stock program? thanks for any help on subject.

 

No chip needed for the t/b.

 

thanks for the info. i wanted to see what mods i can add safely before a chip.

 

is the throttle body acutally worth the doe i would be dropping in it...although i sure do like the way they look but how many hp or torque does it really add?

 

I'd like to know some stats on this mod also. Thanks, Suavy

 

I put on the BA Bolt T/B, which rocks, and 'r' pump and e-fan and dyno'd a 7 hp gain at the rear wheels with all that. BUT, throttle response is amazing now

 

I think it helps. Anything you can do to get more air in and out of the motor is good. No chip is required, but the gain from reprogramming the chip to richen the fuel would help gain even more HP.

 

Obviously someone who has no clue what they are talking about.

Whatever...:o

 

What soap is saying is richness looses power. Being Lean gains power. you have it backwards.

 

$400 for MAYBE 3 hp is tough to justify IMHO.

Throttle response is noticible however.

The FRPP fitment can be modified withthe L linkage in order to fit. LFP carried them ready to bolt-on at one time. Not sure if they do anymore.

best advice, pick one up second-hand unless $$ isn't a concern and you're looking for instant Bling Bling.

I hear what you are saying, running a little lean will make more power. Just to keep the post short, I suggested a chip reburn. You want to optimize fuel, timing, shift points to compensate for the added air flow. The Principals of Power: Increasing an Engine's Output Maximizing the power output of any engine is fairly basic in theory. Since an engine is fundamentally an air pump, taking in air (and a small dose of fuel), compressing and burning that air, and exhausting the leftover air, it stands to reason that any engine modifications that increase the amount of air flowing through an engine will increase power, and that's the basic theory behind most of today's engine performance parts: Move air into the engine, burn it completely, and move air out.

 

That is what a chip does in the first place........non of those parameters will be changed at all by adding a single blade.

This is semantics here, but sometimes I wonder if everyone really understands what they say. Here are some definitions:

Stoich: Operating with the chemically correct mixture of air and fuel.
Rich: More fuel than Stoich.
Lean: Less fuel than Stoich.
Richer: Adding fuel from where you are at.
Leaner: Taking fuel away from where you are at.

Peak power is definately made when running rich. From the factory, the truck is setup too rich (for reliability reasons) so going Leaner adds power, but still staying on the rich side of Stoich.

A throttle body is usually one of the most worthless mods you can do. A throttle body regulates the airflow going into the engine. When fully open, if the opening is large enough, there is only a small pressure drop accross the opening. Going to a large T-body is only necessary if there is a significant drop in pressure. Maybe for cases with large changes in airflow it is necessary, but only after everything else is done. Since everyone is claiming only small changes in power, that means that the factory throttle body isn't a significant restriction.

A chip can be used to get to more optimum operating points for fuel and air, and also the tranny stuff, rpms, etc. Gaining small amounts of air change (as in the case of upgrading throttle bodies) won't change cylinder pressures and temps enough for there to be a difference, so no chip is needed.

And it really bugs me when people say a throttle body helped out throttle response. It absolutely does no such thing. Since the throttle is larger, then for the same opening angle, it is letting more air and making more power. You can accomplish the same thing with the factory T-body by just pushing the pedal further. Its just perception since the same change in pedal position makes more power. If you go to a bigger T-body, you trade perception of better throttle reponse (than you can get anyway by just moving the pedal further) for controllability you get with a larger range of motion to regulate the air. Remember that the next time you have trouble controlling tire spin off the line!

 

I have to agree with you on everything White Lite. If the TB is one of the only mods to be done, then I probably wouldn't go with it because the stock TB is not a significant restriction, and for the cost of the new TB, not a lot of gain will be had. When I installed it with my combination at the time, however, I saw a 4 tenths and 2 mph gain. A lot of that would be attributed to the weather conditions though (10 degrees cooler and a little less humidity).
