Davey Bee Posted January 8, 2002 Share Posted January 8, 2002 I'm thinking of fitting a close ratio box as maybe my next upgrade. I know that Quaife are a popular choice, however there is Caterhams six speed, SP Components five speed, and I'm sure a host of others. My car is a Vx with a 215bhp conversion, but at some time in the future I intend hoping to go for a 240bhp upgrade. It would be nice to know the advantages/disadvantages and experience that others have had with each type of box. Thanks Dave Link to comment Share on other sites More sharing options...

I reply to every thread Posted January 9, 2002 Share Posted January 9, 2002 I can only speak of the Quaiffe C/R HD straight cut box. I changed to one of these a couple of months ago. If you're going from the standard Type 9 the new ratios are a marvel, but you do tend to rev the nuts off it more than before. Pretty noisy, 5th being particularly "musical" but it is a great noise. Certainly less refined than the type 9 - but if you wanted refinement you wouldn't have a 7. All in all I'd recommend it. Credit to Phil Stewart for rebuilding the "Excellent Condition" box I bought! & Mr Webb for skinning his knuckles (& generally making an unnecessary fuss) putting it in. Oh & Redline for coming to the rescue in unsocial hours. Link to comment Share on other sites More sharing options...
oilyhands Posted January 9, 2002 Share Posted January 9, 2002 I've used a BGH (Brian Hill) Rocket 5 CR box in my seven for 5 years or so, it is helical and has excellent ratios (2.58 1st, .90 5th), a superb change and no undue noise.. it has also stood up to 185ft/lb and 250BHP with no problems and was a deal cheaper than the Quaife equivalent. I've had experience of Quaife boxes in the past and while very good they are expensive and noisy. Oily Link to comment Share on other sites More sharing options...
Paul Turner Posted January 9, 2002 Share Posted January 9, 2002 I agree with Oily, my BGH box has been in for 3 years (1800 x-flow) and is great, I just hope it will be OK with the 2 litre Zetec. I choose the sport as opposed to Rocket ratios as they were a bit cheaper, Brian Hill also said they were also totally silent, he was right, he also advised the HD build whatever that was. Previously I had used 2 four speed quaifes, the first a modified sport box was great and virtually silent but I changed it to a rocket pro when I fitted the all steel 1800. The rocket was indestructible (rated at 270hp) but was extreemly noisy. BGH is on 01580 714114. Paul Link to comment Share on other sites More sharing options...
