jpaero Posted February 13, 2009 Posted February 13, 2009 Hello people, recently purchased a 2003 350z. Alot has been done to the car, it has amuse ecu upgrade, apexi safc2, mapped etc but i put it on a rolling road and it came up with 250bhp. Can someone help me with this. This is way too low Quote
Stew Posted February 13, 2009 Posted February 13, 2009 Maybe posting the dyno curves would help. by the way. Quote
jpaero Posted February 13, 2009 Author Posted February 13, 2009 i havent got a scanner at the minute as i'm travelling in a mates car. I have the print out beside me though. Quote
N1SM0350z Posted February 13, 2009 Posted February 13, 2009 is that at the wheels power or..? as stew said post the charts up when you can Quote
jpaero Posted February 13, 2009 Author Posted February 13, 2009 thats at the fly. Its really annoyed me and i cant understand why it is so low Quote
jpaero Posted February 13, 2009 Author Posted February 13, 2009 it reads 250.2 bhp (110mph) 230.8lbft Need help urgently on this one Quote
M13KYF Posted February 13, 2009 Posted February 13, 2009 perhaps some thing have been taken off and a remap hasn't been done. Why the urgency Quote
jpaero Posted February 13, 2009 Author Posted February 13, 2009 its just annoying me and a need to get back tot the dealer i bought it off. I'm also going to another tuner to look at the apexi safc 2 to see if it is set correctly. Thought it might have been that but really not sure as i am not experienced in these cars at all. There was one thing. The boy got a new engine put in as there was a flood and flooded his engine. Could this have anything to do with it? Quote
jpaero Posted February 13, 2009 Author Posted February 13, 2009 was looking to see at least 300bhp. 250 is really low i thought?? Quote
rtbiscuit Posted February 13, 2009 Posted February 13, 2009 depends on where it was tuned, or if you have any other extras, if something was taken off and no retune was done then it won't be as high. are you running it on 98 ron fuel, if your putting bog standard in you can easily drop 15 bhp off the performance. also remember that the bhp guide of 276 on a 2003 is a manufactures guide, its not guarenteed they will actually be that. also remember that different dynos read differently, you'll never get the same read out on 2 different dynos no 2 different days.

jpaero Posted February 13, 2009 Author Posted February 13, 2009 everythin was done at rc developments. Alot of money was spent on it. The car is always run on super unleaded. Our cars are always put on these rollers as we have our rolling road days there so wouldnt think it would be the rollers. Need to get it resolved so i can get the max out of the car Quote

Need to get it resolved so i can get the max out of the car I think for a 2003 with no FI you'd be at the limit trying to reach 300bhp without spending a serious amount of money. Well over 10k. Quote
P15UL T Posted February 13, 2009 Posted February 13, 2009 i would have thought close to 300bhp would have been possible with a remappable ecu , exhaust , filter, plenum space, sports cats etc,, probably just need to remap the ecu, do the dyno tuners not offer this ? Quote

Was thinking about Adams car and the route he took and the expense Quote
3FIDDYZ Posted February 13, 2009 Posted February 13, 2009 Just on this, amuse dont recommend that there ECU's are used over here... something to do with the fuel maps that are in their ECU's... It may have come off an import car.... With regards to the engine swap, did they do an ECU replacement? It is low considering what you have but then the stock ECU can also overpower an add on over time if its not fitted right... Where you based? I would recommed taking it too another turner with a dyno like Gary @ GTart and see what they come up with.. Get the dyno up and lets see... Quote
M13KYF Posted February 13, 2009 Posted February 13, 2009 RC Developments are based in Warrington so I assume he's around there Quote
ZMANALEX Posted February 13, 2009 Posted February 13, 2009 If it was truly only putting out 250 at the fly you would definately know. Quote
Guest prescience Posted February 13, 2009 Posted February 13, 2009 What are the wheel numbers? If they didn't give you the wheel numbers, you've wasted your £££ Quote
Chris`I Posted February 13, 2009 Posted February 13, 2009 I thought RC Developement went under? Was a thread on the MLR just before Phil picked up his GTR? Also what fudge factor did they use to get from wheel to fly figures? Could it be they used a really low figure and hence fly figures are low? Quote
jpaero Posted February 13, 2009 Author Posted February 13, 2009 went to another tuner there. He got the car running as close as he can to perfect. Its now 260bhp, 228 at the wheels with 238lbft. He said that 2003 models he has had in are around the same. Your views? Quote
Ekona Posted February 13, 2009 Posted February 13, 2009 If other cars like yours are around the same figure, then I've got to say it's either the dyno or the operator. Without wanting to sound like a broken record, post the graphs up so we can all have a look at them. Quote
Trev-the-Rev Posted February 13, 2009 Posted February 13, 2009 I thought RC Developement went under? Was a thread on the MLR just before Phil picked up his GTR? Yeah sadly RC are no more Quote
