I am currently running Rocket RE-GRIND cams from Kteller in my Type SH with TYPE-S pistons and Rocket's valve train. Would the JUN III's be a big improvement? Are the JUN's a good street able cam? This car is my DD.

 

I don't know the specs of the RM re grinds but I know some of their cams are more agressive than JUNs.
JUNs are just a great off the shelf cam and will provide an 8000rpm+ powerband.
They are very streetable and idle pretty near stock but are a little noisy.
I love mine, but every setup is different. I am running almost 11:1cr and have awesome power from 3500+.
They will also work great with the RM valvetrain.......
What are you tuning with and what power was made with the Rocket cams?

 

I haven't dyno'd the rocket cams, but it was street tuned with a VAFC2. I would like to keep my ATTS so an ECU swap is out for now.

Where did you purchase your JUN cams?

TypeS pistons and Rocket cams with no dyno?!
Man, street tuning that setup is just leaving power on the table.....power you spent thousands to obtain.

I bought mine used from a local club member....$800 and only used on the dyno. I run them with a SuperTech VT and GE cams gears.
Power starts dropping at 8300rpms or so.

Also, just a tid bit, no such thing as Jun III Cams for an H22.

Only way to know if the Jun Cams would be an improvement would to look up the Specs of each Cam and compare them. We don't know the regrind Specs of the RM-Cams off hand and I'm sure we can find the Jun Cam Specs if we had too. (At least I don't know the RM-Cams off hand.)

Find that out and then maybe you'll get your answer, otherwise, you could be buying a smaller cam than what you have. Don't waste time and money, do the research.

 

A guy dyno'd the Rocket H22 regrinds ages ago and produced a result that was basically identical to his stock JDM cams, iirc.

If he just has an AFC, though, it's not like he's tuning timing anyway. At least not intentionally

 

test them out and let us know

 

Yeah you really need a way to independently tune fuel and timing before you decide if the JUN are better. At the moment your not using those cams to their full potential, so if you think logically about it the cams, atm aren't really a bottleneck for you.

but if you can get the spec from your re-grinds, jun list their specs on their site so just compare and go from there, but you really need a better tuning solution to use either cam to close it's full potential.

unfortunately all the ones that come to mind would require an ECU swap and the loss of ATTS, thats always upgradeable by an LSD =P

 

what jun stage cams did use...i got a 97 sh....i live in california...you thinks what stage of cams should i put on my lude but be able to passed the smog....and what do i need with the cams so i will not have any problems....thanks ...

 

jun only has one profile for the h22

^^Maybe I should of just went right to the point.

The H22 doesn't normally have many production Profiles to choice from from manufactures.

 

i dont really understand regrinds, can someone explain. if im correct you send you stock cam cores and they are reground to different specs? wont you sacrifice lift for duration?

and if people would take a second to check out rocket cams, he would never compare regrinds to a fresh grind. the old comparison dyno was against the typeS cams and only showed a few hp over that. no BS from rocket.

 

no, they take a blank cam and grind their own specs.

 

then why is it called a regrind?

 

hmmm....well you got me there.

maybe they dont alter the peak lift and only the opening and closing ramps?

 

even he says its a little hard to understand. pretty damn old thread...

quite a thread there jacob.......

 

its amazing what you can find with that search thingey

 

HT politics go deeper than anyone can imagine.....

 

theres alot of rocket haters out there. but you cant compare apples to oranges.

the M21 regrinds are advertised as 274 duration and 11.6 left at 0mm lift, so probably like 260 at 0.5mm? and a JUN is what 296 duration and 12.2 lift on the intake and 11.9 on the exhaust. but they dont say at what height the duration is measured at. the JUNs are somwhere between the H22X and the H24X

 

rockets regrinds were just that , a regrind of a jdm h22 cam .

however he does make a full line of h22 cams out of blanks.

i never heard anything great about the regrinds , and goign from them to jun cams is goign to be a big difference

Reground stock cams...
From blanks they would just be custom grinds.
