mkirby Posted April 20, 2006 Share Posted April 20, 2006 Had my project 300 mapped the other day and it didnt produce the power i was hoping for which i know a few reasons why but still theres a niggling thing which bothers me and i cant call the mapper as he;s away for a few days now so thought i would get some advice on here. When he set up the dyno for some reason the barometer was reading really low pressure (700) and he even said its the lowest he has ever seen so he inputted this into the dyno to allow for it but when he had mapped it and we did some power runs the barometer was reading over 1000!? Now i know i'm looking for any excuse to make me feel better but i was expecting alot more than what i got so would this make any difference?? Many thanks Mike Quote Link to comment Share on other sites More sharing options...
lust2luv Posted April 20, 2006 Share Posted April 20, 2006 I'd say he needs a new barometer, it takes something like a cat 5 hurricane for pressure to dip below 900 at sea level. Or was the dyno on top of Mount Everest?! Quote Link to comment Share on other sites More sharing options...
mkirby Posted April 20, 2006 Author Share Posted April 20, 2006 but would if effect the power readings on the car or am i clutching at straws lol Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 21, 2006 Share Posted April 21, 2006 Fiddling with the barometer settings is one of the usual ways of manipulating the final 'adjusted' figures in the eternal struggle to keep the punters happy. (i.e. give abnormally large PUB figures) Looks like they got it wrong here, he he... Quote Link to comment Share on other sites More sharing options...

Cheers for that, so i am right in assuming that if the pressure was 30% higher than he set in the dyno then i will most likely have more power than was listed?? Dont get me wrong i'm not after a nice power reading to show off just a true reflection Mike Quote Link to comment Share on other sites More sharing options...
mkirby Posted April 21, 2006 Author Share Posted April 21, 2006 Heres a pic of the dyno read out http://www.kirbz-zed.co.uk/scan0001.jpg The mapper did say i am losing alot of power from 5000 revs due to the fact my intake pipework is not big enough to provide the turbos with enough air so from there it went very rich so he had to back the fueling off and at 6000 revs he couldnt back it off anymore as it was starting to dett so i suppose if you went up on the map to 7800 revs which it should be pulling hard to the redline with the turbos i have it should have made 550+ but it means i have to take out the engine....again!! to fit larger pipework!!! God i have tuning cars Must admit its bloody quick on boost and i did seriously doubt the power readings from having high power cars before so i may for reference take it down to thor for a hubs reading Mike Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 21, 2006 Share Posted April 21, 2006 If they dyno 'thinks' that you are on mount Everest (low barometric pressure) then it will multiply the real figure by a considerable amount in order to bring it down to earth standards. Same with ambient temperature. If it 'thinks' that it is extremely hot, it will compensate for human living conditions and not Vulcan. Look at this one from my site. 52C in central Scotland, the punter had a smile like the Chesire cat. More on the subject, along with relevant links.

mkirby Posted April 21, 2006 Author Share Posted April 21, 2006 Well its funny because he did say he could input it as a higher intake temp to fudge the figures, not that he would do it but it will be interesting to see with the right pressure settings what power she is making because theres cars out there that i know off running less boost, smaller turbos, less engine work etc and making 30+ rwhp more than i did so there must be something wrong lol Car does sound well at 1.5 bar with its 2 screamer pipes though Quote Link to comment Share on other sites More sharing options...

Yes, there must be:d ...particularly if they can't even get into the 12s on the 1/4mile Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 21, 2006 Share Posted April 21, 2006 ...The mapper did say i am losing alot of power from 5000 revs due to the fact my intake pipework is not big enough to provide the turbos with enough air so from there it went very rich I hadn't heard this one before:D So it's running rich at the top end because the intake pipework is not man enough. Wild guess: he can readily supply you with massive, bling pipework that will simultaneously increase airflow and fix your AFR 'problems' right?

John, you have to remember than tuning 300's is hard work!! and no one really does it so theres not many big power ones around so alot of what me and my mate are doing is all new!? so most cars that have got close to the 12's are all BPU bu this year there 3 or 4 300's coming out with reasonable power John, no he was right and never offered any items i took the car to a respected tuner to get their advice and they did agree that my 50mm intake pipework on my big turbos simply cannot supply enough air and the turbos will be working extra hard to make the boost. Terry, no that is Macca who has a very similar setup to mine but he is making more power than me at the moment. Mike Quote Link to comment Share on other sites More sharing options...

That does sound small, but you've got two of these, right? The zed is different kettle of fish compared to the inline six alternatives, that is true. The bleedin tight bonnet space doesn't make things any easier, does it? But it does look sleek and sexy:d If I had a zed it would be filled with water/meth injectors. I wouldn't bother blaming intercoolers or pipework, since everything is so tightly packaged. Quote Link to comment Share on other sites More sharing options...

I wouldn't bother blaming intercoolers or pipework, since everything is so tightly packaged. i think its also to do with the length of the pipework to the turbos as it comes from near the bottom rear of each side up and under the lights, makes a 90 degree turn and the filters are sat behind the fmic so i would guess a good 3 foot of pipe to pull air through!! so ive ordered a load of 76mm ali pipework to make some more up which will involve a little cutting but going to mount the filters where the side mounts used to be for a little more flow.

JohnA Posted April 21, 2006 Share Posted April 21, 2006 ... the filters are sat behind the fmic ... That's terrible, you've got to figure out a way to shield them from the heat. Cold-air intakes ideally. You could easily lose 5-10% bhp under full load because of this, plus you may be licking the detonation threshold for no good reason:Pling: Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 21, 2006 Share Posted April 21, 2006 480rwhp, thats not unimpressive. ~ 550 bhp? I guess you were hoping for 600 at the wheels? Quote Link to comment Share on other sites More sharing options...

I guess you were hoping for 600 at the wheels? yep i was, mainly down to the fact i know the smaller version of my turbos have made 600 at the wheels so bigger ones shouldnt have any problems?? but looks like i need to do more work to help it get there with regars to the filters behind the fmic, it was the only place we could get them without major fabrication as there meant to go there but its also meant to have smic so looks like its gonna be loads more work I do like the look of that supra engine conversion though Quote Link to comment Share on other sites More sharing options...

paul mac Posted April 22, 2006 Share Posted April 22, 2006 Mike i did all my own I/C pipe work routing (jonny got it welded up) and really sympathise after seeing the intake pipework on a zed if you want an intake pipework "party" you supply the tea and me and jonny could mull it over with you, 3 heads has gotta be better than 1 Quote Link to comment Share on other sites More sharing options...
