One of the Indy Pace Cars - or - NASCAR Camaro or Firebird - used a Dual Quat Throttle Body . Someone on the Gm_efi list hipped me to it - can't find the note at the moment . Looking at building a Tri-Power TPS set-up for a 400cu.in. Pontiac motor- using the 7749 GM ECM. Just need to get correct cfm ratings - operates with MAP - so no MAF wire to work with. Might try & find some old dElL'OrTO carb bodies & core them out.......... dunno ....hmmm. Brien.

In fact you CAN do it yourself! Check out this site, http://www.bgsoflex.com/megasquirt.html I have one of these kits now that I have just started on. It will be used on my son's 78 Toyota pickup (it currently has a 410cfm Weber on it). I found an old "Iron Puke" donor car that I will be using to supply all the sensor's and TB. Bruce Hevner
