Throttle body flow specs..anyone have cfm ratings

[spyder7724]

looking for CFM ratings for the stock, GT500 and single blade.
-Also does anyone make a CAI or inlet tube that will mate to the GT500 T\B that is of the stock elbow design
thanks

IIRC the monoblade TB is 1,600 & 1,900 CFM

I think JLT's kit has what you are looking for...can the math be done for the stock TB bring twin 55's?

 

[spyder7724]

not sure but i can't imagine it flows more than 700cfm.
what i'm looking for is a bigger tube. the onei have matches the stock t\b but it's too sall for the gt500 t\b

Mike @ KB told me that their monoblade flows 1450 CFM... FWIW.

yeah i bought the gt500 tb and i ran into the same problem. the coupler out of the gt500 tb that comes with has to attached to the jlt tube which both are plactic causing it to collapse. does anyone make a brace that goes inside or like spyder said a different tube?

yeah that's similar to what i have now. just looking for a tube thats the same diameter as the gt500tb but made for a GT.....guess i gotta make something else huh..

i dont know on that. also one more thing is that when using that coupler and the tb adaptor it pushes the jlt to the front hitting the power steering reservoir.

yeah had that problem with the stock intake-gt500tb-spacer combo as well. with the JPCintake manifold i don't need the spacer since it's set up for the big t\b but that coupler necks down quick and i can'timagine it flows well into the inlet of the t\b....i may be wrong but i just don't like it.
maybe i can talk JJ at woodbine motorsports into doing a high flow tube that mates to the big t\b...he makes them for lightnings and stuff so i'm sure they can work something up for this since it's the same size t\b inlet.

sounds good. whatever you do let me know by this thread or pm.

There is someone selling a FRRP/Accufab TB that had CFM numbers listed for stock and the FRRP.

Flow will change depending on what they are bolted too.

 

[Greg Hazlett]

I assume the BBK 62mm will flow the same as the FRRP?

wow awesome!!!! thanks.
it's not surprising why the aftermarket t\b's don't make any morepower than a stock if it flows that well. highly doubt i need more than 1100cfm right now so no need to swap that out.
