spiderpigcity Posted August 17, 2011 Share Posted August 17, 2011 Any opinions on the above? does the billet really make 80-100 bhp more or is it just hype? Quote Link to comment Share on other sites More sharing options...
johnny g Posted August 17, 2011 Share Posted August 17, 2011 I'd just look at what pre-billet T67's were putting out - vs what someone like Ricky49 has put out. I don't think it's 100bhp, but it's worthwhile. Quote Link to comment Share on other sites More sharing options...
JamieP Posted August 17, 2011 Share Posted August 17, 2011 I went from cast wheel T67dbb .68 to Billet 6765dbb .81 and added a set of 256/256 cams, at the same boost level i gained 100bhp, went from 630 to 730 bhp on the same dyno. Quote Link to comment Share on other sites More sharing options...
Ricky49 Posted August 17, 2011 Share Posted August 17, 2011 Im on a PT billet Journal 6765 1.00AR and made 644 at the wheels @1.7bar and semi aggressive cams I don't know what a similar 67 DBB would of made though. Quote Link to comment Share on other sites More sharing options...
