B20 Dyno Numbers - 468whp
Uncorrected:
SAE:
Last year I managed to put out 417whp on this set-up with an inline pro manifold and 2.5" downpipe at around 23psi. Since then, the customer has upgraded to the peak boost manifold and 3" downpipe.
For some reason these boost controllers are really hating me lately. The TurboXS Dual Stage Boost Controller is having issues holding boost after 6700ish rpm's. On the last few runs the boost would fall from 24.5psi to 20-21psi unfortunately. As you can see from the last run, it would have kept making power but I noticed the injector was very close to being maxed out so I had to let off on that pull. So with that said, I decided that further tuning would not really do much good until larger injectors are installed and the boost issue is resolved. This was also done on pump gas. The turbo was JUST starting to make some good power too.
I was really wanting to break 500 with this set-up...
Pictures added:
Specs:
Sleeved Block
84.5mm pistons
9.0:1 compression
Eagle Rods (7/16 head)
PeakBoost EQ Turbo Manifold
3" Downpipe
750cc Injectors
Hondata s200 EMS
SC61 .60 E comp .63 ar t3 turbine
2.5" IC piping
Precision 600hp IC
OEM Headgasket and ARP Studs
Minor Head work
Crower dual valve springs and turbo cams
NGK 3330's
MSD Blaster Coil

Re: B20 Dyno Numbers - 468whp (PrecisionH23a)
awesome 
you should post this up in the LS turbo thread, not a LS but these guys would love to hear about the setup. Many of us are running 84mm+ blocks

why would he want that? when he's shifting down that track, a LS tranny will set him up perfect each shift. This motor doesnt need to stay in high RPM's to make HP or TQ. I personaly think a LS tranny would work great while a ITR tranny will have him running outta gear by the 1/8th.
anyways... when he is WOT shifting down that track, it'll stay in boost and fall back to the sweet spot that motor loves.

The powerband is larger than 1600rpms. If you read the post, on the last pull I let off because the injector was close to maxing out. Also around 6700rpms the boost started to taper off... I was going to most likely rev it to around 8000 if I could have had the boost hold steady at 24.5psi which would have given plenty of a large enough powerband.
Sleeved block, CP pistons, eagle rods (7/16 bolt), pump gas.

Re: (SOHC_MShue)
Crower valve train and turbo cams. I managed to pick up 19whp by playing with the cams on the dyno at 17psi.
The head was ported and polished but it's a horrible job. The ports are all uneven and look like ****.... so technically I wouldn't even call it a worked head.

Making good power even with the shitty ports

When I'm talking shitty... I'm talking shitty. The ports are a joke. The part where the ports split into 2 going to the valves the angles are completely off on all 4 ports. The split area isn't even straight... it's all crooked.
I'll have some pictures in a few hours.... I need to put some finishing touches on everything.

Just curious, how hard did you run the injectors (duty) before you cut back?
