Kgerrie157 Posted October 7, 2015 Posted October 7, 2015 Hi All, I thought I would join the forum as it seems like a place to meet Subaru owners. My first post is about the Dyno that I had done today. I have attached the Dyno Chart. The car is a 2006 WRX 2.5 5 Speed Is 316bhp and 380Lbft low with the following Mods? - Custom Map Forged Engine VF48 with Billet Wheel @ 1.35 Bar (Standard Actuator) Uprated STI TMIC GT Spec Headers DW 320lph Fuel Pump K&N Panel Filter 3 inch Downpipe with 2.5 inch to Prodrive Backbox Standard BOV/Injectors Other Mods- Just to introduce myself Alcon Front Brakes, BC Coilovers, TD wheels
quit Posted October 8, 2015 Posted October 8, 2015 Graph looks ok , kinda smooth flow Who mapped it ? Thought the vf48 could run more
Gaulson Posted October 8, 2015 Posted October 8, 2015 Welcome to the club and nice power output there. You are fairly local to me, where abouts you from in Cumbria? Be good to see pics of your car as well ;)
GeoffLeggy Posted October 8, 2015 Posted October 8, 2015 Nice power and torque peak. Doesn't like something up around 5k does it, power starts to wane then fuel goes nuts and power increases. Do you feel that?
confusedbrog Posted October 8, 2015 Posted October 8, 2015 Nice to see another cumbrian in here. You've got a bit less power than me but a bit more torque.
Kgerrie157 Posted October 8, 2015 Author Posted October 8, 2015 I am in West Cumbria the age blip was a wiggling probe on last run so you don't feel it yea I thought vf48 would flow 350bhp at least I think it may need to be ran at 1.5 bar to get 350 with a forge actuator and 3 port for more control injectors have duty left so plan now is to get that done and another map it was mapped by TD Developments in Leamington he is really good that was on 99 v power BTW
Tidgy Posted October 9, 2015 Posted October 9, 2015 welcome, summit wrong with the way it was run by the looks of it, bhp/ftlb crossing point is in the wrong place. should cross at 5200rpm ish
confusedbrog Posted October 9, 2015 Posted October 9, 2015 That's mine with a turbo back exhaust and remap
confusedbrog Posted October 9, 2015 Posted October 9, 2015 welcome, summit wrong with the way it was run by the looks of it, bhp/ftlb crossing point is in the wrong place. should cross at 5200rpm ish tidgy, his graph is misleading because the numbers on the left aren't the same for hp and torque like our graphs are
confusedbrog Posted October 9, 2015 Posted October 9, 2015 At 5200 rpm the power and torque are both almost bang on 300
savage bulldogs Posted October 9, 2015 Posted October 9, 2015 I don't know much about newage tuning and even less about the 2.5 ltr wrx stock injectors. What size are they ? As I think on a newage 2ltr at standard pressure 480cc max about 320 hp 300 flbs 550's max about 370 hp 350 flbs I know the 2.5 naturally has more torque but I think the bigger cc would probably use more fuel and therfore max out the injectors sooner ? The blip in the afr does suggest a posible fuelling change but that could be due to dyno load (what fuels been allowed in a different gear) and could be just from when it comes on boost
Kgerrie157 Posted October 9, 2015 Author Posted October 9, 2015 Yea, Looks very similar Confused, the mapper said there was loads of duty left, I suppose it is a cheapish solution when getting it mapped again to put a set of 750cc's in. (They are already 550cc in 2.5) Do you guys reckon that the 2.5 inch after the 3inch downpipe could be having an effect on peak power? - if so new list! Forge Actuator, 3 Port Boost Solenoid, 3 inch Cat back, 750cc injectors, another map Conusedbrog, What boost are you running?
confusedbrog Posted October 9, 2015 Posted October 9, 2015 Mines getting 1.49 on the digital gauge but the gauge only goes to 1.5. What fuel are you using? Scoobyclinic wanted me to get the car mapped on Shell but we decided to get it done on BP ultimate as it's a pain in the !Removed! getting Shell round our way, but even now the car I run it with BP with a bottle of octane boost or make the trip to penrith when I can be arsed
Kgerrie157 Posted October 10, 2015 Author Posted October 10, 2015 I run 99 pal v power I also have a full decat and get spec headers so should be getting 350 at least Yea I think it needs 1.5 bar and that should give me 350
Kgerrie157 Posted October 10, 2015 Author Posted October 10, 2015 Tbh should see more torque at 1.5 aswell
confusedbrog Posted October 10, 2015 Posted October 10, 2015 My gauge records the peak do it goes up to 1.49 only for a moment then settles at about 1.2 so maybe that number is more relevant I'm not sure
Tidgy Posted October 12, 2015 Posted October 12, 2015 tidgy, his graph is misleading because the numbers on the left aren't the same for hp and torque like our graphs are yeah fair call that. tbh i would sack the vf48 and chuck an aftermarket one on and swap out the injectors and then get it mapped, the graph on min is a sc46+ on low boost, forged 2.5, 3 inch decat, sti inlet manifold, sti top mount and perin inlet pipe. Injectors gave up the ghost at 330bhp though. May find its time to go aftermarket ecu as well, will be struggling to cope with it. can tell from my boost afr graph the ecu was struggling with the fueling as the boost came in
