Thanks BaBolt, I agree with you on every point as I know people who are manufactures and vendors and you never know, but some people get reputations. I live outside Detroit. There is a guy who works in the area that I know pretty well that has worked with intake manifolds and inlet designs on various blowers, as well as some Eatons. My strong suit is more traditional supercharged drag racing without the EFI etc. And basically I think of an engine as an air pump. And it all has to work together as a system in unison. Change one aspect and it affects the whole pump in some way. I think the most critical aspects of these engines is everything before the rotors and after the exhaust valves.

Thanks,
Darin

 

Darin,
Don't forget the heads, especially on the exhaust valve side.

 

what i'm worried about since i'm in the market for a single blade TB is this sticking issue. i've heard at least one instance where it led to great danger for the driver and the truck. are single blades more likely to stick? i've only heard this on a truck w/ an aftermarket unit so i dont know if this rules out the possibility of a factory TB sticking....

i know this may sound like a newb question but what do ya expect

 

I believe in the Geranimals theory. Everything must match. Bigger isnt better. That was proven back in the develop of go fast parts for the 5.0 302. Matching works a whole lot better then force feeding. BA, you still offering any products for us in the Lightning area?

 

so the difference in size is creating the sticking?

 

When i ran an Accufab on the Cobra, there was no sticking nor was there a big problem reported with sticking. I dont see why thiis affects only the Lightning. Is it the positon of height with the linkage? A 4.6 is much shorter in deck.

 

I had a problem with mine not closing all the way,
and may still have. I think that it was a manufacturing
glitch, and probably was just my particular T/B. The
fellas that installed it rotated the "blade" and filed the
end of it to relieve the closing area. Seemed to work
OK.

I don't know if there is a increase in HP, but the single
does seem to be a bit more "responsive" on the low end.

The issue of sticking or "stickion" is usually seen at the transition of closed to opening. It can happen to almost all types but in the better designs it is rare. The factory Ford items are very good high quality items (their function is excellent and they well go well beyond 100,000 miles) . The Accu-Fab units are quality items too and there is always a place in my heart for billet items.. There are other throttle bodies that are made (copied) but are not engineered that suffer a whole host of issues. It is not my point to list the faults with these other designs or to discuse a fix. To my friends I will provide free engineering services but you must remember one thing you get what you pay for . As for horsepower claims on an oval bore throttle body I always told people about 6 to 8 HP and Ft lbs. on a stock motor. What is noticable is the little kick in the pants on initial tip in. Also please note I do not advertise here and I am not looking to generate interest or sales. What I do not like to see is outragous claims and products that make "Lab Rats" out of customers. A customer should never be asked to hack and wack on their vehicles to fit an item and when it comes time for removal the added item should be able to be removed without destruction to itself or surounding conponents. Now please don't read a whold lot into this. I have seen the vendors at this site make some great strides and the product quality has improved a whold lot from the early days of 1999. It just needs to continue. Interesting article in the January issue of Hemmings Rods & Performance "Porting for Power".

 

I have sold over 300 T/B's in the last 2 years. A little over 200 were the FRPP unit that i would convert using a new Lightning specific cam lever. When they were discontinued earlier in the yr. I began offering the billet Accu-Fab. I have had one Accu-Fab returned to me for sticking. I wouldn't concern myself. As BaBolt has expressed, there are many reasons for sticking.
Also, I'll would also have to agree with him, on the point, that Bigger isn't necessarily always better. To big and it will fall on it's face.
