Dyno graph w/ 5858 and GSC cams
heres my graph and video, tuning was done by Slowmotion Motorsports and on a Dyna Pack dyno, on the big pods
specs
-GSR block, 81.5 bore and stock sleeves
-manley rod, 10:1 CP piston block guard
-ITR crank and oil pump
-GSR head ported by me, supertech valvetrain, GSC 288 cams
-BWR topmount t3 manifold, journal bearing Precision 5858
-ID1000 inj. and BBK intake manifold
-this tune is on 93 octane and 16 psi
and a video

Re: Dyno graph w/ 5858 and GSC cams
i will post a correct final C16 video and graph tomorrow once its done being tuned, so far 25 psi and nearly 600 whp and 400 wtq stopping ~8k because we were completely out of fuel

Re: Dyno graph w/ 5858 and GSC cams
Im a GSC T1 owner myself. I'm just saying its completely abnormal for a Honda B series engine to increase in VE like that and create 60 more foot pounds of torque if manifold pressure is remaining constant. Unless there is something else at play like the timing advance is ideal only at redline but very soft in the mid range. The most logical answer is boost creep.
Im very curious now so any data you have would be appreciated.

Re: Dyno graph w/ 5858 and GSC cams
You can see after 6k on the pump gas dyno graph that something happens...
from 5000-5500 you can see a rather steady power curve trend developing then suddenly at 6000rpm hp and tq start to creep up in a very jumpy fashion, which says to me it's a creep problem.
are you sure your log is accurate? what about you map sensor and boost gauge?
I'm gonna have to side with Muckman on this one
and it's wild just how laggy a topmount manifold will make even the smallest of turbos when compared to the same turbo on a manifold with shorter runners

Re: Dyno graph w/ 5858 and GSC cams
I don't see why you guys are so focused on boost creep.... If the guy is happy so be it. Keeping the TQ lower at lower RPM prevents wheel spin on the street and can be adjusted through a PWM solenoid.
Spool isn't bad, makes 200TQ about 250RPM after my ram horn on a .63ar
Looks like the highest HP I've seen on a 5858 so far, great job!

Re: Dyno graph w/ 5858 and GSC cams
pump ran out on race gas tune around 600whp.
Not to shabby for stock lines, filter,fuel rail and FPR with just a drop in wally 255

Exactly, i love the powerband, wastegate (on pump) is open before 5k rpm and the 5858 is .82 A/R also, which could contribute to slower spool, but i love it up top

Re: Dyno graph w/ 5858 and GSC cams
And *UPDATE*
i put in a walbro 460 today, still on 25 psi, we maxed out my ID1000's at around 640
whp and 410ish wtq, i dont have the actual graph yet, just video and pic of dyno
screen.
I plan to get some 2200's and try and push it a little further, but that may wait till
spring, my intercooler is beyond maxed out, (when i started this build, i was only
planning on 400whp range haha)

i normally take it to 9k, but with my injectors maxed the tuner didnt want to go higher than 8500
