MAF and throttle body question

[AKfun4wheelin]

tryed this in the under the hood section but no luck so I am moving it here.
When going to a Granatelli MAF and a BBK throttle body is there any thing you have to do besides installing them and resetting the computer? they are basic bolt right on and thats it right? Any one had any problems after install like check engine light or something?

 

[ChuckyD]

Yup... should be a basic bolt on like you said... and i havent herd of any problems. I also herd that you shouldnt bother with the MAF. Send Alec a PM, He knows about the BBK.

 

[AKfun4wheelin]

Thank's! I thought they should be a strait bolt on, but I wanted to be sure.

Yeah, the only thing I don't understand is that BBK says that it's a 66mm thottlebody, but I measured mine (stock) the other day and it measured 66mm, so what does $250 get you then? Especially when EE says that it's "significantly larger than stock" or something to that effect?

 

[AKfun4wheelin]

yours is a second Gen X I think they my be bigger?

 

[DasFrem]

That's kind of sketchy then since they say it's for a 91-00 OHV engine. I was always thinking of getting one, until I was doing some work on getting my TB to get a more WOT and measured it. Has anybody measured their Gen I Explorer TBs?

 

[AKfun4wheelin]

just did tonight. the inner diameter right it the front is close to 65 mm, but as you go back to the butterfly it is only about 56 mm. so if the BBK is 66 mm at the butterfly it is bigger by almost 10 mm which is a decent difference

 

[DasFrem]

Ah Ha! So there is no conspiracy after all! Well I guess that piece is going back on my wish list.

me to working on the wife now!

:redexp: Never noticed any real change after bolting on the Granatelli. The BBK throttle body is another story all together - that thing made the ol' X jump! No problem with install of either component - both straight forward bolt-ons. I'd suggest getting a throttle body spacer as long as you are at it. Helix Power Tower was an easy install on my 96'.

everything i've heard here and elsewhere has been that throttle body spacers don't work on non-carburated applications so don't waste your money.

btw- signatures that spell out every little thing are annoying...
