redeagle

Did a run on Superflow 4wd dyno today after building 3" DP last night.
Setup:
1.6 stock engine 203t.km (rebuilded ~20t.km ago)
RX-7 460cc injectors
BEGI Cast manifold from Shanghai-S kit
3" DP
2,5" exchaust
MBC
Noname IC (2,5" inlet/outlet)
IC piping 2,5"
MSPNP
Coolant reroute
1.8 lightened flywheel and FM Level 1 clutch
Garret GT2860RS with 0.64 A/R
3" AEM airfilter

174,2kw(236,8WHP)\281,6Nm(207.7lb-ft)
Boost 17-18 PSI (still creeping 2-3PSI)
Not the createst one, but car pulls strong and fun to drive.
Will post proper dyno file, video and log/setup from MS over the weekend

Here's one of the log files from dyno (hope someone cares to comment it).
Also better graph on best run.

peak torque in ft-lbs should be

70 to 72 ft-lbs * 1.6L * (1+boost/14.7)

At 17 psi should be > 240 ft-lbs or 323 N-m

It is lower than most dyno pulls here.
I can think of 3 reasons:

1. Something wrong with engine/setup altough engine sounds healty and compression/leakdown shows no issues (headjob is unknow quality so might benefit fromthere)
2. Euro 1.6 has different cam profile
3. Dyno i used reads low, really wanted to do comparison on dynojet one we have here, but it's broken at the moment.

280hp on 460's seems high for the injectors. I was running out of injector at about 260 even with methanol.

I think these 460cc measured 490cc and dutycycle according to log is 79-80

I was reading it wrong thats 236whp thats sounds right i was thinking it said 280hp. Does seem a little low for that pressure and that turbo, but who knows with dynos honestly it could just be reading low. If you can take it the track and get a mph and time you would know what its making.

How much timing are you running in boost?

I saw your log and you AFR under boost are oscilate between 11.9 and 12.2 and as you increase on RPM is set around 12.1. Is it me or that a bit too lean for the boost he is running?

Yeah seems lean should be low 11's
