Alan Bowler Posted May 11, 2012 Share Posted May 11, 2012 Friend around the corner is building an Ultima. The engine has just been delivered, but he won't be ready for it to go in for a while. What class would I be in with.... 702 bhp / 645 ft lb? On Yoko A539 tyres of course. May need launch control too. 702 bhp is really just 189.99 in class 4 speak, right?

robmar Posted May 11, 2012 Share Posted May 11, 2012 on list 1a's I would have thought you would need more than launch control. Just de tune it to 189.9 for class4 . Probably just a tad over tickover for that BHP 😬 rob Link to comment Share on other sites More sharing options...
Mark Durrant Posted May 14, 2012 Share Posted May 14, 2012 AB I think you concentrate on making the most of the R300 engine before changing classes 😳 😬 Link to comment Share on other sites More sharing options...
Alan Bowler Posted May 14, 2012 Author Share Posted May 14, 2012 I just need a larger spanner to adjust the nut behind the wheel. The Corvette engine isn't very light - nearly put my back out dragging it into the garage. AB Link to comment Share on other sites More sharing options...
