Supercharged 2 Posted October 15, 2009 Very impressive for a non crossflow head... and fair play to Berno considering the hassle he's had with the engine (...and then he bought the broken half of Henny's one :lol: ) http://www.dubforce.net/forums/index.ph ... opic=18598 This is Sam's (Blue Joe's) old engine with Henny's big valve CNC head running a 62mm pulley and 4 branch etc... Vince did as much as he could mapping it but this would be capable of the magic 300bhp Sam was after if only RPM had built the engine to the correct compression ratio! Basically it's setup with virtually no advance - a spacer gasket of ideally different pistons should make this an absolute monster 8) Power output 3k - 135 bhp 4k - 188 bhp 5k - 244 bhp 6k - 264 bhp 6309k - 276.1 bhp (peak) 6776k - 250 bhp (max rpm) Torque output 2k - 188 lbFt 3k - 230 lbFt 4k - 245 lbFt 5k - 250 lbFt 6k - 240 lbFt Quote Share this post Link to post Share on other sites

Kevin Bacon 5 Posted October 15, 2009 Great spread of torque from 3 to 6K :salute: Never heard of RPM? Who are they? Doesn't sound like a place I'd want to take my car if they can c0ck up something as simple as compression ratio! Quote Share this post Link to post Share on other sites
Supercharged 2 Posted October 15, 2009 Race Power Motorsport - Sam had loads of issues with them and there is a lot of bad press if you have a google... Like you said, muppets! Quote Share this post Link to post Share on other sites

Supercharged 2 Posted October 15, 2009 Nah - just check every 10-12k - not that bad at all, regular servicing is key! I'm running a 10mm on mine - basically a bolt coming out of the charger with the belt wrapped round it :) Quote Share this post Link to post Share on other sites

CTWG60 0 Posted October 15, 2009 Ooops it's broke already, the charger that is! 62mm = too much! Well my lick continues, the FU*K**G charger went down this morning and developed a running fault. As soon as the engine started I could hear a tapping noise. Stripped the charger off in 15 minutes, Getting use to this now! Quote Share this post Link to post Share on other sites

mrbeige 0 Posted October 15, 2009 Isn't a 62mm pulley just asking for trouble though? Quote Share this post Link to post Share on other sites

CTWG60 0 Posted October 15, 2009 You find out how quickly your wobbly thing likes wobble! Being technical about it! 6800*1.7=11,560 with a standard pulley increase the wobbling by some 30-40% and your looking at more than 15000rpm, ouch! If it was kept below 6000rpm then he could of kept it within spec at 13200rpm. Quote Share this post Link to post Share on other sites

CTWG60 0 Posted October 15, 2009 :lol: Has it stopped eating clutches and gearboxes now? Yeah but it still has expensive tastes. I think he should start making it drink diesel and remove the spark plugs, I think it would be content that way. Quote Share this post Link to post Share on other sites

Neil VR6 0 Posted October 15, 2009 The way it would pick up from 2k RPM and not need to be revved to 4k RPM like the VR before the fun begins! :ignore: Quote Share this post Link to post Share on other sites
Jim 1 Posted October 16, 2009 I think with the G60, it was never a perfect design and things such as 62mm pulleys and tooth belt pulleys etc were well outside of the scope for which it was originally designed. I think some head improvements, a marginally smaller pulley, big FMIC and a remap are pretty much where you should draw the line between a healthy power increase and weekly trips to the garage to get things fixed.

dirtytorque 0 Posted October 16, 2009 Without trawling, what is the CR of that engine? No one knows. I will say that the dish looks similar to the dish on my new pistons. Obviously the 8v cylinder head has a much smaller combustion chamber. Quote Share this post Link to post Share on other sites
Henny 0 Posted October 16, 2009 When Sam had it built it was said to have a C/R of 9.5:1... but no-one's ever actually proven that... Mine had (before I sold the head!) a C/R of 9:1 and I had no problems with the compression ratio... Oh, and Race Power essentially built the bottom end of my engine too as JMR commissioned them to do the work to his spec when I got him to build the original 1940cc lump for me... (it's since been rebuilt twice for various reasons, and is about to be rebuilt again around a PG block instead of a 1H one! :cuckoo: ) Quote Share this post Link to post Share on other sites
