hey guys.

whats up? ok. a few months ago i got my motor rebuilt on my itr. had new pistons installed, rods, mugen head gasket and tuned with hondata s300. now. i purchased some cams that were supposed to be RM m22xx's. but when my car got on the dyno, the numbers were low. i made 170whp. this set up should have made me close to 200whp.

anyways how can i tell what cams they are exactly. i know they are RM. i think they are the M24's. i am getting skunk2 pro2's installed this week. so i will be selling the other cams.


thanks

 

Pro-Is would suit your setup better.

 

There's a few rocket dealers floating around the All Motor forum.

And for a non-stock setup, your numbers are pretty bleh. I'd check that everything is running up to par before you blame it on the cams.

 

well. i know its the cams because my setup is similar to another H-T member. the only thing is the cams. the vtec on my car is set at 7200rpms. when it should be set at 6k or so. i have to rev the crap out of my motor 9200rpms to get 170? something is not right.

but anyways, i am putting the cams in this week. i will post the cams for sale on the calssifieds section

thanks

 

... Sounds like you should get a tuner, or a tuner who knows what he's doing.

 

the tuner that worked on my car has tuned alot of cars on hondata/kpro/custom setups. he even asked me, what cams are u running? looks like the are BIG cams..

 

Then why did he set the VTEC at 7,200RPM?

 

the vtec was set that high because any lowe. and the power curve dropped.. the higher we set the vtec crossover.. the better it was.. that was an indication of big cams he said.. might be meant for a 2.0 setup with really high CR.

 

What kind of dyno? What does a stock ITR put down on this exact dyno? 170whp would not be that low on a Mustang dyno.

 

sounds like something else is a little off to be honest


when i had my car tuned with Jun 3's on a stock bottom end, another guy there had specially organised with the head of Jun (can't remember his name off the top of my head) to receive Spec 4's.


with those, Wiseco pistons and god knows what else expensive parts, he made LESS power than me. same tuner, same dyno, same day


something was wrong. but it wasn't the individual parts or the tune

 

the car was dynoed on a dynojet.

 

You don't have the stock cams? Try dropping those in with another dyno. Then you'll know where the problem lies.

 

m22xx ctr pistons, 310cc 200 whp @ 8000 rpm for me

 

Email me some pics of the cams.

M24's would make more than M22X, but the powerband would be shifted up a good bit.

Who was your dealer for the cams?

 

Specs of your engine?

 

i will post pics today when i get the cams changed to the skunk2.

engine specs..98jdm itr motor. weisco 81.5mm pistons w/mugen head gasket= 12.0 CR. ARP head studs, eagle rods. rc 310 injectors, rmf header tuned with hondata s300

 

Here are the pics of the cams that were in my car.. Last week i got the skunk2 pro2's installed. i still need to get car tuned.

these cams seemed to be too BIG for my setup.. M24's?

let me know what you guys think

 

i think the pro 2s are too big for you engine,,i think you need at least 12.0 to 1 compression to run those..Is your bottom end stock or what

 

i have 12.1 compression. my bottom end includes weisco pistons and eagle rods., rmf header, 2.5 exhaust, tuned with hondata s300.

 

i still think that pro 1's would have been better for your setup, and yes with vtec at 7200 it seems those RM cams were too big for your displacement/compression

let us know how the pro2's do

 

Can you measure the cams secondaries? Can't tell by the pic if they are M22 or M24.

the way the secondary and VTEC lobes are so similar for lift remind me of Toda C's


looks like they'll make a shitload of swirl. too much? i'll let you be the judge

 

Something else is defnitely up. Vtec at 7200? Are you serious? Of course the tq curve will drop... that's how you tune the Vtec but I'm at 4100 myself... so I think something else is up BIG TIME other than just cams.

any work done to the head besides it being an ITR head ? .. intake manifold TB ? .. any idea what duty cycle the 310's are at right now ?
besides it being too big of a cam , it can also be because ur motor is not flowing enough , or maybe something physically is wrong with the motor .. btw , did the car get street tuned and break in ?

 

Could be an intake tract problem. I've seen a low velocity IM (CNC ported ITR IM...) do that. M22's only made a few more hp than stock R cams due to the IM.
