How much do they charge for dyno and when are you going?
If you can provide a link that would be great.Not sure if they are still available but you used to be able to get rubber adapters for radiator hoses at the auto parts stores. If you had an odd sized outlet pipe on a radiator, you would slip the rubber ring on the outlet and then slip the larger radiator hose over the ring. Tighten with a clamp and you're done. Might give that a try on your throttle body or cold pipe.
65mm is the butterfly. Stock RS is 57mm, stock Mustang is 60mm.Thanks for all the measurements @nicklulu ! It's interesting that your FP inner (70mm) is the same size as the Mustang outer diameter. So it could also swallow that one, if the hose barb was removed.
Now we just need someone to get the BBK to complete this. I'm very curious if the "65mm" is the entrance or the butterfly. Based off the labeling of these other products, I'm thinking it might be the entrance.
You've measured the BBK? I was unsure about the advertised size of the BBK because different places seem to advertise throttle bodys differently, either by the entrance size or the butterfly size.... or some arbitrary value in-between. Like Damond says the stock Mustang tb is 63mm. Ford Performance's "70mm" throttle body has a 70mm entrance and a 67mm butterfly (according to @nicklulu).65mm is the butterfly. Stock RS is 57mm, stock Mustang is 60mm.
Here is one example but not the only mfg. that makes them. They come in a small number of sizes.If you can provide a link that would be great.
Thank you for the tip!
