Blue Line = JUN 3's

Red Line = Toda B's

just a comparison, nothing else, I have Toda B's

 

around 195 at the wheels with just those mods? that seems damn good, i wouldnt have expected that much.

 

red line all the way, baby.

jason- who is on the anti-peak power/respect the midrange campaign

 

haha!

The JUN3 make power fo sho. But I gotta agree with DV on the midrange.

-Dave, who is sick of typing "both JUN and Toda cams can make power"...

 

The Toda Car is gonna be the faster car cuz it has the better powerband, better area under the curve

 

You could use that arguement.. until the person shifts out of first anyways...

 

Is this the same dyno plot MikeK posted up awhile back?

 

yes

 

.....faster in what way?

The jun car can launch at a higher rpm since it's making less whp and tq lower in the powerband, and it will then get into vtec sooner and ultimately to redline sooner... Then after each shift, it will be in it's element - which is at peak for each shift after that.

The toda car will get wheelspin if it launches as high as the jun car, so it will accelerate a little slower, but then the midrange will have it pulling back on the jun car. 1-2 shift will see the toda car lose a little to the jun car... repeat for gears 3-5.....

This is a straight line, assuming equal drivers, cars, weight, etc...

Now on a road course or autox, there is a good argument that unless you are in the 2k rpms before the rev limiter, then the toda car will give you better results.

Now, what about a spec c car is my question... I believe the spec c's offer the best compromise of both worlds - good midrange AND good peak power.

Also, you guys left out the debate that the toda car seems to have been tuned for the midrange... You could tune for better peak on the b's and maybe take up some of the slack that is between the two plots in the higher rpms... But ultimately, the jun 3's will have better peak than spec b's - assuming equal time tuning and equal mods. (imho)

Well, yes,

imho both have a right to exist... It depends on the driving you do..
For me, I would prefer Toda B, though I`ve bought JUN 2 now. According to Toda my valvesprings are too stiff for Toda B`s.

Quartermile is not in my interest, I don`t like races beeing over after a few seconds

On a road/ralley track it`s midrange that counts. There is nothing greater than pulling strong out of the turn.

But I really wonder which one of both cams make better topspeed..
topspeed races are very common where I live. I guess the JUN.

 

I prefer JUN 3. I always try to stay above 6k rpm as much as possible. Toda has a bit more mid range, but JUN just dominates the top end. I still like JUN for all racing use.

Any plots for the Toda C ?

 

I have a question for you knowledgable Toda guys, I'm about to do the Toda B's.. I bought the B's a month ago and I'm having second thoughts. I was serioulsy thinking about the A's but I was like well if I'm going to do the work I might as well put the best cams I can in. I'm installing them at the end of this month. Now I'm going to be putting them in my GSR(mods listed below in signature) with the correct valvetrain components, electronic upgrades, and the only boost in compression is going to be a Spoon Sports Head Gasket(NO OTHER HEADWORK, ie. port, polish, shaving). So I maybe be able to get 10.4:1 Compression Ratio. I'd like to upgrade to higher compression pistons later on but the cams and components, electronic upgrades, and 90k mile maintenance is costing me $4000! (Breaking the bank) I wouldn't be able to save up for another year and half to build the bottom end. I'd love to get 185WHP and that would justify the upgrade. Current UNTUNED dyno chart(posted on my webpage) uncorrected was 154whp. Do you think I'm just setting myself up for a big dissapointment here?

 

yes.

206.9hp 138.1tq

 

The owner of this car never did any road race.. but he was consistently 2-3 tenths faster in the 1/4 mile with the JUN setup.

Here in Naples, we're stoplight confrontation/drag race *****.

 

FO sho dog knockin on the Riced out civic's

 

LOL... so true Dunno, but I love my JUN 3's and they do ptitty good at the lights... not that I do any street racing

 

I got 188/130 out of 10.6:1 compression with spec B's. I think there's more in it, so I'd say 185 is realistic for you.

 

ok i have to ask. What the hell is in the 90k service that costs $4k?????????????

 

Damn

nice results... for both Jun/Toda

they both have advantages/disadvantages

 

I like the Juns better for sure , i dont think my cars sees any less than 7000rpm around the track...

 

As he put in his post, the mods for the rebuild and his 90k service is going to cost 4k, not just the 90k service.

i4: what tracks are you talking about where you don't hit less than 7000rpm?

 

ummm...

 

I'm thinking that he means "drag strip" ( which is fine you damned Drag *****! )

 

If the think the B's are not making enough power for you I think you should go with the C's.
