I didn't think there was one. plus i think it would be pretty pointless considering everyone's motor is different.

There was one, Mike K did it. I don't have a link but I saved his post in my notepad. Here you go:

I don't have any dyno plots yet.. it's just a matter of me finding some time and scanning them on my friend's scanner.. but I've got all the dyno sheets in front of me.

Just a recap, two motors were tested.. each motor got like 8 to 10 runs on tuning. Cam gears, fuel PSI and V-AFC were tuned on both setups.

Motor 1:
B18C5
Head milled 12 thousandths
DC JDM header w/ test pipe
AEM intake and AEM cam gears
V-AFC
Stock exhaust

Cams tested on motor 1:
Toda Spec A
Jun 2 Intake cam / ITR exhaust cam
CTR cams

Bottom line is, the JUN combo absolutely PISSED on the Toda A's all the way from 4000rpm to about 7600rpm(where the JUN's peaked).. then the Todas gradually pulled up until about 8200rpm.. peaking at 184.6
Midrange is a no brainer. JUN2 intake cam is a phenomenal investment. Just wait til you see the chart. And NO, this is not biased at ALL toward the JUNs. Toda A was the only cam I believed in for the past year or so. I'm still in shock to tell you the truth. I mean, JUN2 intake cam with stock exhaust cam. That's HALF the investment of the Todas and it gives all the power where road-racers want it. Enough talking.. I'll just post the chart and you'll see.
As a comparison.. tuned CTR cams were better than the Toda A until about 6000rpm.. then the Todas pulled away hard.
Peak numbers and settings.
JUN2 intake- 180/131 (+6, +1, 44psi, VTEC 5100, timing 20)
Toda A's- 184/131 (+5, +4, 40psi, VTEC 5200, timing 20)
CTR- 179/132 (+4, -0.5, 38psi, VTEC 4900, timing 19)

Motor 2:
B18C5
Endyn 12:1 pistons in 81.5mm bore
Mugen JDM 4-1 header
OBD1 clip w/ Skunk2 P28
Test pipe, Tanabe exhaust w/ bottle necks removed
Portflow inner springs/retainers

Cams tested:
JUN3
Toda Spec B
Toda Spec A

This one is a matter of choice. Best torque was the Toda B with 133.3.. best hp was JUN3 with 195.6..
From 2000-4000rpm all 3 cams were damn close on the charts.
Toda Spec B held about 3-4 hp and ft/lbs over the JUN3 cams from 4000 to 6500.. then the JUN's took over by at least 8hp. The B's peaked a little over 8400 and started to drop.. the JUNs pulled away to 9000. It's pretty obvious to see that the B is for road racer and the JUN3 is for drag racer. Personally, I would pick JUN3 because the idle. That's my only gripe about the B's.
Even MORE shocking is the run with toda A vs. toda B. personally, i think this chart may have some impact when people see it. reason being.. from VTEC transition to about 66-6700.. the A's are AHEAD of the B's in hp and tq! Then, they stay about the same til 8200.. then the B's pull ahead..


peak numbers and final settings
Toda B - 190/133 (+7, +7, 28psi, VTEC 5700, timing 17)
JUN3- 195/130 (-1.5, +1, 48psi, VTEC 5700, timing 17)
Toda A- 186/138 <IMG NAME="icon" SRC="http://images.zeroforum.com/smile/emsmileo.gif" BORDER="0"> (+5, +3, 40psi, VTEC 5500, timing 15)

*FOR THE RECORD* On Motor 1, stock injectors were used with adjustable pressure. On Motor 2, 310cc were used on JUN3 and Toda B.. 270cc was used on Toda A.
I'll post charts soon..
