Just for sharing information ,these are the dyno results of some engines that are running for super touring in my country.Please feel free to give inputs and comments
These are BHP !!



Below are brief description of the specs;

Mike spec :
1)JDM B18c5 with 81,5mm +5cc Wiseco piston and Peak performance H beam rod
2)PNP and milled head (39cc) ,Mugen headgasket andITR intake with 66mm bored TB
3)JUN 4 cams and valvetrain with stock polished ITR valves
4)DC sport titanium race header/ Ebay intake about 1m long
5)Motec M4pro with RC 370cc injectors

Sunny spec:
1)JDM B18c5 with Mahle +9 cc 81.5mm piston and Eagle H beam rod
2)PNP head (43cc) ,toda headgasket and ITR intake with 66mm TB
3)Toda C2 cams and Toda valvetrain with stock polished ITR valves
4)Toda B18 header with 2,5 inch straight pipe to the back and Ebay intake
5)MOtec M4 with RC 370cc injectors

Febril spec( i dont really know the specs of this engine):
1) B20 vtec with Wiseco slugs and forged rod
2)Jenvey ITB, unknown CR and head PNP
3)BC5 cams and Supertech Valves
4)Unknown header
5)Was running Motec too when i saw it last time

I dont really like Sunny graph and was wondering why his hp was downfalling at the top rpm, difference is that his head porting was about +7cc bigger than mine(Mike) on the intake and exhaust and his guides were cut away.Maybe header ? head port or cams ?

Very good info.

But it's difficult to draw any conclusions with the differences in the motors.

Its actually for comparing and learning by looking at the graph, Mike and Sunny were actually made and tuned in the same place but with different PNP and setup.At least i know that the cams and head didnt do good.B20 graph is for comparing powerband between the B18

Thanks for sharing, but imho there are too many variables.

Have mike and sunny swap cams and retune!

I'd expect the jun 4's to be comparable to the toda D's, not the C's.....

now here it is ! i missed the page

yeah im bit wondering why TODA C2 made less power even from the bellow to midrange up to the top rev.
did sunny got the same CR with mike??
or it must be overported so the flow doesnt have air speed &lt;-- if the CR was the same and all of setup exactly the same, so it could be the reason for it..

but anyway, back to your comment of my post , im still saying @#F$@C@# to ekos b20 time slip..
and his motor was very sounded unpowerfull, i dont know what happening if we compare with the graph that look so fat

steve, even your motor knock sunny almost 8hp accross the band, sunny will always knock your brother in the cornering
mike should practice harder, beware, sunny was a real fighter
thum ub for you both

carboy_honda

Consider the flight time of both driver , he has been racing for 15 years.I took it as a challenge,both teams have ups and down.It just sucks that we develops under the same roof, all the works and development thats done could be seen by the other car then copy it.Sunnys head when he bought was already ported by some crazy guy who heck everthing out to about 137cc (intake port) exhaust is around 95cc.Both motor CR is about the same ,he got +9cc dome and 43cc chamber while mine is +5cc dome and 39cc chamber.Anyone know the drivetrain loss % in Honda ?

nice to see some info on these cams...

Car Boy - I am considering getting the Toda C2. I was supposed to get a crower 403 but decided on the Toda C2. How does the car with the Toda C2 idle? Is it lumpy? I heard the old Toda C's were very lumpy. What was the compression like with the car with the Toda? I was thinking of putting ctr pistons if it needed it. But I would like to stick to my 11.1 comp ratio. I have a JDM ITR. Are you based in Jakarta?

Well its not very lumpy compared to non vtec engines running high cam, Iam running sequential injection with Motec so it idles like a stocker and C/R is around 13,4.Depending on your Ecu setup and Compression basically the lower your CR the lumpier it gets during idle with high cam.Are u daily driving the car ?Air con ?If yes then i recommend Jun 3(stocklike idle).Your C/R is not high enough for considerable gain to run the C2 in my opinion,you might want to consider Toda B or JUN 3(JUN 3 has more top end in my experience) Btw i am building another engine for my street race car with ac and they be running JUN 3 with 12,8 C/R.Yes iam based in JKT.

jt-sport

steve , could you list compare the specs between toda C and toda C2 ???

D0GMAN

yep every motor is completely different. but thats for sharing tho

carboy_honda

Have to find the specs to be really sure but it is the same centerlobe 102,5 if i remember correctly,intake exhasut open closing is the same too.Difference is the +5 degree duration.Btw the primary cam was off by 2,5 degree when dialling.

camlob

I'll using aircon and the car will be a daily driver. I was planning to put CTR pistons. Do you think the CTR pistons will provide enough compression for the Toda C2's? What is your opinion on the Toda A2's? Is it too mild? There are no Jun 3's available here. Can you recommend a dealer in Singapore?

emir

if u still prefer toda product then you can go with toda B, better midrange and a bit of topend. If u plan to take ur ITR until 8.5k rpm then toda b will works fine.
U can get Jun3 complete set in KL, if u want ...i got the contact

camlob

Emir - Thanks anyway. I'm in Sing now but will be heading to Bangkok on Sat. I won't have time to go to K.L. I'll just visit the toda dealer here in Sing. Looks like the toda b has the specs that seem good. I would want to get the intake closing ABDC to better calculate the crank pressure vs. stock.

Hi Steve,
I think Febril spec is:
85mm Wiseco (+8,1 cc)
H-Beam Eagle Rods
Cometic head gasket ( 0.73mm thickness )
40cc's B16A head
Mugen 4-1 B16A header
V-AFC apexi with H22A injectors

What is the difference between the new TODA C2 spec and the older TODA C? Anyone?

jt-sport

c2 more duration (arround 4 degree each) from the c

wheres the dyno graph? although its a very old thread.
