Having pretty much established that the JRSC is out of puff at some ~360 hp (at the hubs), plan B was called for:
Yes, that's it, add a huge turbo! (Garrett GTX3582r), in a compound-charged setup blowing though the JRSC.
after a lot of messing about, ended up with this:
Blue line is the same car from last year, Red is current, (numbers are from TDi's Rotatest, at the hubs, DIN corrected.)
obviously, the engine is no longer a standard K20A2, it's been Datron'ed to 89mm with rods and pistons, then the std head put back on just with new valvesprings (built for us by Paul Exon of
Exon Race Engines).
The car belongs to Jamie Willson, who has been using it to win Time attack Club class in 2010, Club Pro in 2012 and now entered in Pro-Extreme for 2013.
After a bit of a false start at Cadwell, spent 2 days on TDi's dyno to get the bugs worked though, the engine package is just about there, and to be blunt, it's a monster!, can't belive how fast you have to pull the next gear, and remember this is with a full sequential gearbox with paddle-shifter (
Eliseparts box and
Geartronics shifter).
