Seen some 70mm throttle bodies on Ebay, just wondering if anyone has 1 of these and did it make a noticable difference???

funny you should say that i gained 1 psi for that reason today the hole the throttle body mounted up to was ofset by about 4mm to the throttle body and i dident realise so out came the drill and diegrinder bit all fixed nowon a stock engine i think you'll gain some throttle response. probably not much in actual total power output. on a blown engine it's probably a different story as anything in the path from the blower to the combustion chamber will quickly become a restriction
ahh kk man i though the acutrally part that connects to the pipe was bigger and aswell the metal peice the in the tbWogBoyz, it's only bigger on the inside makes no difference to the piping etc, but my car was running 9.101 1/8th miles on stock headers and a single cat. The next meeting I changed to pacemakers, twin cats and a 70mm throttle and ran 9.032 (it was actually slower over the first part of the track). A decent gain really when your chasing hundreths of a second like I am, but I'd take the bet none of that was from the throttle body. To put that in Perspective I went from a 9.4 to 9.2? on pretty much just a good CAI (and I allready had the factory one which in itself was worth serious tenths over the pod I bought it with)
