paulgtt Posted November 28, 2015 Share Posted November 28, 2015 Took my newly acquired glanza on the dyno today at Noble Motorsport but was slightly disappointed with the figures tbh, the car drives absolutely brilliantly but I'm a bit puzzled by the boost.It's got a Blitz sbc boost controller and on it's max setting is set to 1.4 bar (it has gone up to 1.5bar on the display but I put that down to the colder weather), on the dyno there boost charts are showing a max of 1.2bar and the dyno operator did say that the controller was only showing 1.2bar max aswell. Now obviously as a result of this the figures seemed low, 235hp and 202ftlb @ fly, car was dynoed with previous owner at 218hp @ wheels which would equate to somewhere around 260ish?I know no two dynos are the same when it comes to power figures but surely the boost should be the same? I haven't got today's graph to hand but the boost is rock solid 1.2bar across the revs, the fuelling is rich at 0.6 lambda (I only know afr so not sure what that equates to) and at 7k rpm they seem to be picking up a slight misfire, curves are nice and smooth and it is still making power up the top end until the misfire, haven't noticed this miss when driving it though.Anyone any thoughts? And yes the controller was in it's highest setting lol! Quote Link to post Share on other sites
Socks Posted November 28, 2015 Share Posted November 28, 2015 What is a Quick Spec for the car? Did you setup the boost controller yourself? Get the graphs up bud so we can take a look! Quote Link to post Share on other sites

We turned it onto 1bar setting when I picked the car up as it was wet and then a couple of days later turned it onto the 1.4bar setting and left it on that since, I've not adjusted anything else that I know of. Won't be able to get the graph until next week as I left it there like a numpty! Everything on it looks fine to me, but the 0.2bar must be costing it a fair chunk of power.

ro55ifumi Posted November 28, 2015 Share Posted November 28, 2015 Paul Sent you the graphs when mapped at TD, have asked Will for a copy as can't find them on this pc.It was 218 on TD map and finished at 220 at Will's John Quote Link to post Share on other sites
paulgtt Posted November 28, 2015 Author Share Posted November 28, 2015 Cheers John, if you can get hold of the other graph aswell that would be good. Quote Link to post Share on other sites
AdamB Posted November 29, 2015 Share Posted November 29, 2015 (edited) 0.6 lambda is extremely rich! Surprised it even runs.That's about an AFR of 8 ish. That's like Ethanol AFR's. Edited November 29, 2015 by AdamB Quote Link to post Share on other sites
paulgtt Posted November 29, 2015 Author Share Posted November 29, 2015 There was a fair bit of over fuelling out the exhaust whilst it was on the dyno so I've left the car with them and they are going to tweek the emanage, hopefully it's not locked otherwise be start from scratch.

Rob H@RCH Engineering Posted November 29, 2015 Share Posted November 29, 2015 If it was that rich the plugs would be black, have you checked the plugs? When this was on the dyno at Wills there was an issue with the rocker cover breather pipes shorting out the king lead, check thats not happening again because that causes a miss fire under load and it would also make it run rich as its not burning the fuel properly.

paulgtt Posted November 29, 2015 Author Share Posted November 29, 2015 No as the cars not with me.I've left it with them to underseal it and they were going to look at the map at same time. They are calling Monday with what they find but if it is something simple like that then I'd investigate it myself before changing maps etc Quote Link to post Share on other sites
Rob H@RCH Engineering Posted November 29, 2015 Share Posted November 29, 2015 Like Adam said if it was that rich in the map it would not run properly and it would drink fuel, I think its something else causing the problem. >https://www.youtube.com/watch?v=WERU_oq9DvE I should have a dyno reading for it too but im struggling to find it too!

paulgtt Posted November 29, 2015 Author Share Posted November 29, 2015 I think it must be something else as it uses hardly any fuel and drives spot on, I've not noticed any misfire either.Im collecting next weekend so il see what they say about and then il check plugs, leads etc. Suppose it won't hurt to change the plugs whilst I'm checking them tbh. I would like to see the fuelling on the previous graphs to compare.Il probably take it to another dyno next year and see if that reads any different to Nobles. Quote Link to post Share on other sites

5e colin Posted December 11, 2015 Share Posted December 11, 2015 did you find the problem paul ?? did you get it remapped Quote Link to post Share on other sites
AdamB Posted December 12, 2015 Share Posted December 12, 2015 Try a different boost controller. Some of those SBC units are known for solenoid failures, and hence won't produce the desired boost pressure, that may be why the car is running rich because it's not getting the air its expecting.

paulgtt Posted December 12, 2015 Author Share Posted December 12, 2015 No I didn't get it remapped in the end as I wanted to check the plugs etc first.On the way back it was boosting up to the normal amount so I reckon it must of been something to do with the sensor at the dyno, also checked plugs when I got home and they looked perfectly fine too.Took the car out last night to pick the missus up from a party and it was boosting perfectly fine up to 1.48bar then aswell, so everything as normal!
