Each set of cams were tuned..not just swapping. Here is the before/after of the Toda Spec Ds:



-Rod

 

Dam that can't be true with the Toda Ds. I would of thought they made more power than the skunk2's. There has to be a conspiracy!

 

looks like the stage 2 Skunk2 cam can keep up pretty well, thats good to know

 

Probably see more power with the D's and higher compression.

 

is that b19coupe's motor?

Taken from his signature:
Current engine-Benson sleeved GSR block with 84mm bore, custom JE 12.5:1 pistons,Crower rods, ARP head studs, stock head gasket bored to 84mm by GE. Portflow Type-R head,Toda "D"s, Toda valvesprings, TiN coated Portflow retainers, PE timing belt,Hondata Intake gasket. AEM cam gears, FPR, & CAI. Erick's Racing 70-68mm throttle body, RC440cc injectors, DC Sports JDM 4-1 header(soon? to be replaced by HyTech), Modified Type-R b-pipe, and stock Type-R muffler

 

i dont think theres enough compression and whats up with the head? is it stock?

 

But I could say the same thing for the Skunk type 3's..they are nearly the same size cam as the D's. 12.7 MM VS 12.9 MM??

So more compression is going to help the 3's alot more too.

The thing is, your going to be able to run more compression with the Skunk 3's than the D's because the D's are slightly bigger.

So the 3's might be even that much more better.

Thats the other side of the coin for the compression argument. Who knows which would do better on a 15:1 motor. For sure, all 3 here are going to be good.

I'm no NA guru, but is the fact that the stage 3's and the D's make peak HP at 7700 a little low?

 

Wow thats a shocker,i guess for his motor the skunks would be best for the price.Around $750 for a set of skunk 2/3's vs. $1150 for toda d's.Thank you guys over at IB's and the peps who participated for the dyno plots,i cant wait to see more

thats what i was thinking.
and a fully built 84mm motor making only 207 whp with 141 tq?

is there something wrong here?

So when is it going to be tested on a real motor with compression in that range...

The numbers at the bottom are MPH, not RPM...they may line up though...not familar with the exact trannsmission he's using.

 

This motor is not living up to it's potential. Either there is a problem with the head porting, the compression is too low, or a combination of both. The power peaks too early, and too low. While 207 is quite respectable, for the amount of time and money in this motor, it is disappointing to say the least. New higher compression pistons are now in this motors future, as well as other changes. I don't think that this motor gave the Toda's what they needed in order to showcase their stuff. I have to say that the Skunk2 Stage 3 cams impressed me, for the money, they are a great cam. One more thing in closing, the mid-range on the Toda's is very nice, and you can really feel it when driving the vehicle. I have to thank Jeff, he spent alot of his time dialing in these cams and playing with the A/F ratio, not to mention giving up his dyno for the day. Thanks again Jeff!

A header and exhaust will make a big difference.

 

Well even though the numbers seam shallow... It is still good information...

Thanx, I feel very comforted to know that the money I will put into stage 2's won't be a retarted descision...

 

We did try an SMS header and a IB modified JG header, and though they made more peak, it's not as though they kicked the DC's butt. There is something fundamentally wrong with the motor, which needs to be addressed.

 

have you ported and polished your head?erics does the best work he helped me with my setup,its not as aggresive as yours an eric said i should be making 215-230 wph.give him a call.

 

The thought crossed my mind. I got the cams from him,and I am getting a clutch from him. I need to get a different head, because this one has already been ported, by someone well respected in the industry. I am not going to say that the porting is the problem for sure, because the problem may lie elsewhere, but you can bet that we will find out where the problem lies.

 

the head is were the most power is going to be found especially in n/a motors. what head are you running?get the competion port and polish its like 1200$ but its worth it.

 

I think that Toda D's are meant for high RPM engines I tried Skunk 2/3 also jun 3's and they did not work for me, I still think that Skunk and Jum are good cams but you have to remember that deferent combinations are always going to be deferent from engine builders.

so what are you running now?

 

Toda D's

 

Ummm... Rob's GS-R with Skunk2 Stage 1's with Bolt ons, ECU, and some other stuff made around 190wHP with stock bottom end, stock pistons, and some other stock parts.

205wHP with Spec D's and all that other work is kinda weak if you ask me...

Maybe I'm missing something?

If you can read, I wasn't comparing Stage 3's and Toda D's you dumbass.
