I have to agree with Bernd. Allot more flow with Bruce's unit versus
Hughes.

I was gonna say....Bruce has this thing "dialed in".

> Ok folks, I talked to Hughes Engines this morning and Dave has flowed the
4.7L 68mm TB in
stock form, and after his Stage I mod. and here are the DISSAPOINTING
results.

> 65mm TB (Stock) 400 cfm

> 68mm TB (Stock) 420 cfm (5% increase over stock 65mm)
> 68mm TB (Stage I) 454 cfm (1% increase over Stage I 65mm)

> Dave says the "entry radius" is to sharp and there is no material to
broaden
it. We may
have to add an "attachment" on the outside of the TB to extend this entry
radius. This
added piece would be part of the air intake system. Dave is still working on
the 68mm TB
at this time to see if he can make it flow better. I should have it back by
Friday or
Monday. I'll give final flow results at that time. I must add that Dave is
determined to
get the most he can out of the TB, so he's not giving up on it yet!
> A new billet TB, like Bruce's unit sounds like the best idea for major
flow
improvement at
this point. We'd need to compare flow numbers, and price to make a good
judgment.
