Ok guys [and dolls] I’m after some help with understanding throttle bodies and trying to find out if I can do what I want to. I hope you can help.
I want to fit a 2l 16v red top into a 1977 chevette saloon and as at least a starting point for increasing power run the lump on bike throttle bodies. It’s down to cost mainly…I’m still a part time University student and working the rest of the week to cover fees and car parts. I have some formula student contacts as well and so I can get a full set off the engines they get in year in year out, for relatively little monies.
Thing is, they’re off an R6, which if my research is right, have a diameter of 38mm over the R1 and I want to know if this is going to cause any unforeseen problems? As basic numeracy goes I think the following is right:
4mm difference per tb with four tb’s needed = 16mm less than provided by 40mm tb’s
40mm tb’s present 1600mm with four tb’s needed = 6400mm total
[16/6400] x 100 = percentage difference = 0.25% over the whole bank [not that much to make a huge difference right?…]
If anyone could help on this matter that would be great as I really am getting close to the stage where I want to put some money down on the power unit and have to factor in engine management and set up costs as well. I have been researching SBD motorsport and Bogg Brothers too, but don’t want to be going down a road that isn’t going to take me anywhere when I finally ring em up to see about a quotation.
If anyone has tried this before, or knows of someone else considering it then please, ‘fess up, and hopefully I’ll get to be rolling round in a sleeper come 2008 ;D
