309PUG 2 1 Cars Posted March 18, 2007 Quick update plus a thumbs up for Phil @ Power Developments. Phil finally mapped my 8v on DTA and what a cracking job he's done unfortunately his rollers need calibrating so wasn't able to provide a final power / torque figure but he recons around 180 bhp After yesterday testing at Blyton he said get a good feel for the engine and report back any miss givings, bring it back and he will put it back on his rollers after its been calibrated and maybe tweek the start up map a little and provide a power / torque read out. Can recommend this chap to anyone, down to earth, calls a spade a spade you get the picture, his premises are a little over run with cars of various conditions and state of tune. He verifys the output of all the 'Rear Wheel Drive BMW Challenge' cars. Chris Share this post Link to post Share on other sites

pug_ham 244 3 Cars Posted March 19, 2007 Looks & sounds good, nice to see they've fixed some of the potholes at Blyton (not). Graham. Share this post Link to post Share on other sites
smckeown 1 Posted March 19, 2007 nice one, may have a chat to you regarding using your map as my base map I have a question though, if the RR needs calibrating how can he verify the output on the race cars ? sounds odd Share this post Link to post Share on other sites
Sandy 191 Posted March 19, 2007 Nice! Got to love the 8v noise Front end a bit too hard though perhaps? Didn't look like it was digging in, hard to tell from here obviously. Share this post Link to post Share on other sites
Rippthrough 98 Posted March 19, 2007 Nice! Got to love the 8v noise Front end a bit too hard though perhaps? Didn't look like it was digging in, hard to tell from here obviously. I had the same thought, but then that is a rather bumpier track than most places. Share this post Link to post Share on other sites
309PUG 2 1 Cars Posted March 19, 2007 I think I have to agree about it being too stiff upfront, although Blyton is not the smoothest of tracks but its very cheap, local and quiet. Although it may be helped when I fit my super sticky slicks on for sprinting.

smckeown 1 Posted March 19, 2007 quiet a mild cam for such high compression; wouldn't mind seeing what the curves look like. Sounds fantastic and also sounds like the rev limit is high Share this post Link to post Share on other sites
Paintguy 0 Posted March 19, 2007 Oh, I see you went to Blyton after all then. After our conversation earlier in the week about the RR set backs, I understood you'd be getting back to me if this was still on, as I was looking forward to being there. Never mind, it must be something I've said... Share this post Link to post Share on other sites

309PUG 2 1 Cars Posted March 20, 2007 nice one, may have a chat to you regarding using your map as my base map I have a question though, if the RR needs calibrating how can he verify the output on the race cars ? sounds odd He did all the BMW Challenge cars for last season and checked that there were no flyers so to speak, since then he got all the bits to convert his rollers into 4WD, in the middle of all this I turn up for my mapping session, he told me prior to arriving that he wasn't in a position to provide actual figures. Hope that makes sense and clears up any mis givings Sean. Share this post Link to post Share on other sites
Paintguy 0 Posted March 20, 2007 Yeah it was We thought you were coming over too. I reckon you guys just didn't want me taking up valuable track space in my overweight, underpowered, mobile disco! Share this post Link to post Share on other sites
