Enjoy the interesting facts with a dyno to boot:
21 dyno passes were made on each cam to tune them. The 21'st run was very close the potential of these cams on the close to stock ECU we use. DFI or other better ECU's would surely net more power. Note: The JUN valve train, and JUN ECU were not used in this test.
5 were on timing,
6 were on Fuel pressure
6 were on Cam gear settings
4 were micro tuning fuel with a Apex V-AFC
The Toda's base lined at the starting, settings of: 39 PSI fuel on 310 injectors, cam gears 0.0 and timing at 17 degrees. They base lined at 210 at 131 lbs of torque.
The Jun Type 3's base lined at the starting settings at 217 with about 137 lbs of torque.
The Type-R cams base lined at about 202 HP, and the largest gain came when I moved the intake cam to +4, where it immediately gained 5 HP at the wheels. The exhaust cam ended up at +4 and that made the mid range on the type-R's jump up about 10 HP at the wheels....you can see by the chart...the Type-R cams just dominate up to a certain RPM.
This motor once again was a:
Ported GS-R head with ports re-shaped like a B16A
Type-R intake manifold
Type-R throttle body, 62 MM
Iceman primary intake piece and Advanced concepts secondary piece extending the 3" pipe out of the headlight with a K&N filter on it.
Custom header made my Atomic Performance (not for sale)
Muffler shop $80 special 2.5 inch exhaust, all the way to back, no cat.
Greddy 310 Injectors
Stock GSR oil pump, Stock GSR water pump
Morosso Cool can for fuel
Aftermarket radiator, thin (light)
AEM cam gears
The results did not come out as I anticipated, but I tried my best to make the test as fair as possible.
Looks like on our LS/VTEC Motor, the JUN 3's are a good choice for drag racing...obviously you want the Type-R cams for the street.
First 5 runs of each test were made on 92 octane.
Second 5 runs were made on VP 103 unleaded
The remaining 11 runs were made on C-12 leaded.
There was very little to no difference in HP or torque from using any of the higher octane gases over 92 octane pump gas. The C-12 netted a gain of about 1 HP or so above 7,000 RPM.
I hope you guys enjoyed this test as much as I did.
: What are the best cams for a motor with super high air flow?
: Apparently, the high duration of the JUN 3's works well with a motor that breaths very well.
BLUE LINE; 220.9 HP, 141.7 TQ =JUN 3
RED LINE; 208.3 HP, 141.1 TQ =Type-R
GREEN LINE; 215.2 HP, 135.6 TQ = Toda C
Note the color's of the torque lines for each cam. The JUN 3's torque at 8,000 RPM are clearly 5+ lbs of torque higher than either the Type-R or Toda Cams. The Toda Spec C's started to surpass the Type-R cams in HP and TQ at about 8100 RPM.
I hope you all enjoyed this review as much as I did doing it for you all.
For the dyno graph click here:
RATING: JUN Type 3's 96% Mid range could have been better.
RATING: Toda Spec C's 90% Good Cams, Good peak power.
RATING: Type-R 85% Great cams for the money. The best mid range power in our test, perfect idle, good torque.
Comments: JUN 3 cams, a great choice no matter what kind of head you have. The Toda Spec C's netted the 2nd highest horsepower reading at the wheels of all of the cams we have ever tested. So they are still a very good choice. Type-R cams? Honda knows what they are doing...look at that midrange power!
