DaveR Posted August 28, 2015 Author Share Posted August 28, 2015 (edited) First progress update: All is running well. So far, after the initial AFR setup etc and just 2 runs, it's making 500bhp (with still only a 7200rpm Rev limit) on 1bar boost... I think we're going in the right direction!

DaveR Posted August 28, 2015 Author Share Posted August 28, 2015 nice one Dave that was a fast turn around was expecting it to be done in a few months It's been being worked on since the end of March!! This is definitely my favourite part though. Quote Link to comment Share on other sites More sharing options...
abtin90 Posted August 28, 2015 Share Posted August 28, 2015 Wow as above wasn't expecting this to be completed. Be very interesting to see what it makes compared to the old engine. Do you have a goal in mind? Quote Link to comment Share on other sites More sharing options...
DaveR Posted August 28, 2015 Author Share Posted August 28, 2015 Huh. Here's something we didn't anticipate. Romain has all but finished now; it turns out that the engine is now FAR too big (and capable) for the turbo, cams and probably FMIC as well. This means that essentially the car will probably make exactly the same power it used to because the turbo - which was obviously near its maximum capacity previously - simply can't flow the amount of air that the new engine can make use of.

What Cams, FMIC are you running ? So have you stopped at 1.6bar again ? Quote Link to comment Share on other sites More sharing options...
DaveR Posted August 28, 2015 Author Share Posted August 28, 2015 (edited) What Cams, FMIC are you running ? So have you stopped at 1.6bar again ? Still 264 cams with a Whitbitz FMIC. Boost is now 1.7bar with max torque at 4500rpm and max power at 7k rpm Edited August 28, 2015 by DaveR Monged it...

mattdavies Posted August 28, 2015 Share Posted August 28, 2015 Still 256 cams with a Whitbitz FMIC. Boost is now 1.7bar with max torque at 4500rpm and max power at 7k rpm That will keep you going for now then. Start saving to replace those items before another map or leave it as it and Enjoy ??

Had Whifbitz not informed you that this was a possibility when they began building the engine? Does that means a new turbo, cams and fmic are on the cards?

DaveR Posted August 28, 2015 Author Share Posted August 28, 2015 That will keep you going for now then. Start saving to replace those items before another map or leave it as it and Enjoy ?? Bit of both, I think. I'll see how it feels on the road (the most important thing after all) before I decide. Had Whifbitz not informed you that this was a possibility when they began building the engine? Does that means a new turbo, cams and fmic are on the cards? Uh, sort of. I knew that the turbo wouldn't be able to get the absolute most from this engine but I didn't expect SUCH a dramatic disparity. The cams being as underwhelming as they are in this set up is a real shock though, from the point of view of it never having been discussed...

jcbt Posted August 28, 2015 Share Posted August 28, 2015 Well she is alive again which must give you a smile. Understand the limiting factors are probably giving you some angst. As usual for us boys it's will be another dig in the pockets for required uprated parts. Hope you get it how you want soon. Quote Link to comment Share on other sites More sharing options...
Hemanhead Posted August 28, 2015 Share Posted August 28, 2015 Didn't think stroker kits made more power anyway? they just bring the graph left, same power with less rpm. Quote Link to comment Share on other sites More sharing options...
TheTurtleshead Posted August 28, 2015 Share Posted August 28, 2015 (edited) Still 256 cams with a Whitbitz FMIC. Boost is now 1.7bar with max torque at 4500rpm and max power at 7k rpm You sir need a precision Turbo! Mine made max torque @ 4200 RPM(640ft/lbs), max power by 6500, (708bhp) It's a stock block & head, with 256/264 staggered HKS cams. It's also a 62mm (6266 Gen 1 Journal). 6466 PT would bring it alive a bit more for sure, torque & power would probably come on harder and sooner as well.

Paul Whiffin Posted August 28, 2015 Share Posted August 28, 2015 It's the turbo holding the maximum power back Dave, the 264 cams and intercooler are good for 800bhp, we've proven that many times. And don't forget Dyno Dynmanics rolling road will show you a different figure to a Dynapak, you can't compare the 2. It must feel more torquey and better low down on the road than before surely?
