whitestar Posted June 4, 2013 Posted June 4, 2013 (edited) What's the best power you guys have managed to get on ported OEM manifold? I've got almost all the required supporting mods for the 200hp setup, but my manifold is a stock one, only ported. I got 155hp on the fly and I'm thinking it might be the manifold that restricts the setup too much... I have: CT9 @ 1barPorted OEM maniJAM ecudecatFujitsubo catbackApexi filterIridium plugs and ultra leadsFMIC Edited June 4, 2013 by whitestar Quote
iamlegend Posted June 4, 2013 Posted June 4, 2013 (edited) my lord somthing is wrong there.. my old gt with the exact same mods minus the jam ecu (mine had stock) you have made 167 @ 0.8 bar... would get it mapped and mabys change the manifold making sure it is ported... as seen oem manis make good power Edited June 4, 2013 by iamlegend Quote
micky boy Posted June 4, 2013 Posted June 4, 2013 Same here i made 175bhp @0.8bar stock ecu Since fitting the blitz ecu i havent had it RR..Im running a stock ported manifold @1bar atm so i would like to see what bhp figher i make Quote
Foggy Posted June 4, 2013 Posted June 4, 2013 Dunno if that counts but i had a glanza that was mapped in japan on a f con.1.2 bar std mani and cat. Car went for 5years never an issue and went like stink. Quote
whitestar Posted June 4, 2013 Author Posted June 4, 2013 (edited) The JAM ecu makes it run stupidly rich when boostin full boost on higher speeds, might even show 10.0 AFR on my AEM. Here's the dyno graph:Might it be the way too rich mixture? Should I try lowering the boost to 0.65 and test it with stock ecu or could it just be the mani? Any other suggestions?Oh right and the mani is ported for sure, I had it ported myself. Edited June 4, 2013 by whitestar Quote
micky boy Posted June 4, 2013 Posted June 4, 2013 Might be worth trying another P&P ecu see if that helps Also you could try the stock ecu like you have said and see what AFR'S you are getting etc Quote
whitestar Posted June 4, 2013 Author Posted June 4, 2013 I asked JayJ if we could try swapping our JAM ecus so I could go for a test drive with it. He's actually my only hope as I don't know of any other JAM ecus in finland. One thing that might be behind these low power figures on dyno could be the dyno itself or the guy operating it. The car was dynoed in a local university.... Quote
Socks Posted June 4, 2013 Posted June 4, 2013 All dyno's are different... What sort of times can u reach 100mph with a good launch? Old vid of my car: Running similar spec to u! Quote
whitestar Posted June 4, 2013 Author Posted June 4, 2013 (edited) Here's a vid of mine going. https://vimeo.com/67005187 I remember easing out when the speedo was around 120kph, on 3rd gear (I shift to 3rd around 100kph when boosting like that ). So I think it's around the same as yours was? Edited June 4, 2013 by whitestar Quote
whitestar Posted June 4, 2013 Author Posted June 4, 2013 (edited) And that launch wasn't the best tbh Should have shifted to 2nd sooner. And actually your start is a bit rolling, my is stand still. Edited June 4, 2013 by whitestar Quote
AdamB Posted June 4, 2013 Posted June 4, 2013 Have you checked the valve timing and ignition timing. If these have been retarded by like 2 degrees you'll lose a fair amount of peak power. Quote
davehart Posted June 4, 2013 Posted June 4, 2013 Seems a bit low that. My stock EP runs 142bhp with no mods on it at all, only a japspeed system and air filter. Quote
whitestar Posted June 4, 2013 Author Posted June 4, 2013 Have you checked the valve timing and ignition timing. If these have been retarded by like 2 degrees you'll lose a fair amount of peak power. No I haven't. Propably I should take it to some workshop that could check those....Although it runs just fine and feels quite fast, even compared to my mates jap spec s2000 honda! I have to hop into JayJ's ride when he gets all his parts fitted to compare how it should feel. I still think it might be that it's running too rich so it loses power or then the dyno is piece of shit. Quote
Weyro Posted June 4, 2013 Posted June 4, 2013 You definitely sure its a flywheel figure and not a wheel figure? Quote
whitestar Posted June 4, 2013 Author Posted June 4, 2013 (edited) Yup, it's 124 from the wheel. In the graph: orange on top is torque, red is at the fly, blue is at the wheels, pink is boost and green is power loss. Edited June 4, 2013 by whitestar Quote
JayJ Posted June 5, 2013 Posted June 5, 2013 Could it be something to do with the power loss figure, as you lose ~30hp from your maximum power? Would be interesting to see other members dynographs showing the power loss figures. :-) Quote
whitestar Posted June 5, 2013 Author Posted June 5, 2013 Well, the power loss means the loss in between fly and wheels, so I don't think my transmission has anything to do with my fly output. :/ Quote
Weyro Posted June 5, 2013 Posted June 5, 2013 what kind of dyno is it? steady state or inertia? Quote
GAZ@A&G_TUNING Posted June 5, 2013 Posted June 5, 2013 my old old mk1 gt basic mods made 170 at hub's 0.9 bar with fmic and decat stock ecu Quote
maddox710 Posted June 5, 2013 Posted June 5, 2013 Pretty damn good results, i didnt belive stock intercooler and ecu could push out that much power. Quote
EPnick22 Posted June 9, 2013 Posted June 9, 2013 I haven't had my Gt dyno'd yet but i used to have a ported stock mani, with the basic mods, bought an sps mani and it almost scared me how much more power i had in higher revs the first time i took it out Quote
