Brad-ManQ45 Posted July 28, 2004 Share Posted July 28, 2004 Chevy only used it for 1 year on the C4 Vette - 'nuf said? Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted July 28, 2004 Share Posted July 28, 2004 Wasn't it like two TBI type throttle bodys set at opposing sides of the intake manifold? The stumbling half step between TBI and TPI. Quote Link to comment Share on other sites More sharing options...
Guest Phil1934 Posted July 28, 2004 Share Posted July 28, 2004 Turbo City seems to do OK putting them on a 2 4bbl inline intake. The stock setup was poorly received. Quote Link to comment Share on other sites More sharing options...
Guest MistressMotorsports Posted July 31, 2004 Share Posted July 31, 2004 CHevy actually used it two years. In 82 on the last C3 Vette, and on the 84 C4 Vette. (There was no 83 model). I think early third gen F bodies had it as well, but I could be wrong on that. It was actually a pretty cool concept with two TBI units on a cross ram manifold. In theory it could provide the benefits of a much larger manifold while still clearing the hood of a space restricted Vette engine compartment. I had a buddy who got into the 12's with his when a stock Vette was in the 15s, not too bad. I think the biggest issue was not the TBI units, or even the restrictive intake, it was probably the ancillary hardware and computer capacity. I don't think it would be my first choice for an engine build today simply because there are so many reasonable priced port fuel systems around. Although, it would be unique, and could even be fast with some porting and a decent way to tune it. Mike Quote Link to comment Share on other sites More sharing options...
Guest plainswolf Posted July 31, 2004 Share Posted July 31, 2004 Another bad feature about the manifold itself is that it cannot be ported at all. It's almost as if it were cast that way deliberately. There is an aftermarket Crossfire manifold that is cast with slightly larger bores... Called the Xram I believe. you can get fairly decent power from them however it doesn't seem the most cost effective or parts available intake system ever put into production. Bottom line is that it can be made to work very well, but it definitely does have it's limitations.. Quote Link to comment Share on other sites More sharing options...
