Ok so to clear up here on the throttle body that I have been dealing with for the past 48 hours straight. Well I slept between 3am and 7am yesterday so I did take a break but I am exhausted. Here is the deal...

The throttle body is bored to 60mm from stock 55mm. We replace with oversized butterfly and set to stock idle position on the butterfly of 6.5 degrees.

We spent the last couple of day letting the ecu cycle over and over with the throttle body and totally stock tC, take its random samples of the air intake variances, and ran the car for a good 100 miles to see if it would throw any CEL codes. It didnt.

Then we hooked up our intake to force more air into it to see if this would finally throw any codes. It did. The code was for idle throttle position. Basically because the internals are bigger the ECU recognizes more air in the chamber and thinks the position is not at the 6.5 degrees for idle.

The part did yield 2-3 whp N/A , but where the part really pays off is when we have done tests with the turbo. Here you dont have to worry about the CEL because of the turbo system so there goes that problem. Also the amount of horsepower can be maximized and we have seen upwards of 10hp on the turbo system from the 60mm body. As a result our R+D recommended to keep for turbo only applications because of how labor intensive it is to bore out and be within the precise factory tolerances and all the general headaches with it.

Hope this helps to answer some questions...

so no for us non turbo'd?

 

hmm turbo... need some volunters........

 

Why not set it up fully closed and drill a hole in the throttle plate for idle? Start with a #60 drill bit and increase until it will idle and the computer will do the rest. just a thought....

 

or change the angle of the plate negative 1º or 2º ?
