I know a member has posted this dyno graph and i don't know who, but I'm not sure if this dyno is accurate or not and I'm curious to know how me made 210whp with stock head/block with good header/crome tuned/and m22x cams. I been looking around other threads and people haven't been making more then 190whp MAX. I'm still debating if i should run M22x CAMS or skunk2 pro 1's on a stock JDM ITR motor with basic bolt-ons (intake, header, exhaust, test pipe, hondata/crome, cam gears, supertech dual valve springs, portflow retainers).

anyways this is the dyno graph i found a while back.

 

I made 190/135 on a stock JDM 96 ITR w/ dc 4-1, hondata s300, rc 370's, 255 lph, 2.5 exhaust, and sucking thru a stock eg airbox. So i'm sure that if i had changed my cams, then i would have broken 200 whp too. Every motor reacts differently. You just have to find out what makes yours perform better for you.

 

or you can all go to high reading dynos

dyno numbers dont mean a lot comparing 2 different engines...

when will people learn...

 

yeah, did u dyno before the cams?

 

Couldn't be a "stock" head to run cams of that degree. Kind of would need to at least change the springs, no?

I hope the owner of that graph PM's me.

 

PM 92TypeR. I believe he is the owner of that car.

Head is the operative word, not valve train.

 

my friend just made 185whp on a 98spec ITR with Pro 1s, tri-y header and 2.5 exhaust, supertech spring and retainers.
same engine made 180whp completely stock on the same dyno a few months back

 

I bet the new setup kicks the old ones in the usable power area though. HP at 1 RPM doesn't mean jack.

Peak numbers ftw, look at the hump at the top of the run (2-4 whp)

I don't know why but I have a strong feeling that dynochart was tampered with.



See how the tq numbers are not lighter in color ?
Another thing I don't like is they list "actual horsepower & actual torque" instead of SAE numbers

I would like to see a simular setup on an unbiased dynojet at sea level.

Not my car. Was a customer's car tuned over a year go. Stock JDM ITR motor with RM M22X cams + valvetrain. IIRC, he had a J's style intake and 2.5" exhaust of some sort. Here is the original thread click

No reason to tamper with anything. I'm not getting paid and I'm certainly not benefiting from posting charts of tuned cars.

Elevation at INTEC is ~50ft. I got the same type of responses in the original thread a long time ago. There is nothing special or strange about the INTEC dyno, my car made 166whp stock, pretty typical for a stock USDM ITR. Other DynoJet 248c's in the area make within 2hp.

That second graph is my car, not the same car as the graph posted by the OP. Color's are screwed because it was a scanned paper graph, not pulled out of the WinPEP software.

SAE numbers on the customer's car were 207/130. We generally don't print SAE numbers for customers unless they specifically ask, mainly because they don't care what their car makes for power using some correction factor, only what their car makes that day in Seattle. As stated before, we aren't fudging anything.

Hope that clears things up.

 

^ thanks.

 

What's with that dip in the midrange? Couldn't that be tuned out?

 

That dip was due to the header.

The motor could have made great midrange if he wanted to stick with the 1.8L block and bought a 1.8L DTR header. The customer eventually went to a 2.0L bottom end, hence the 2.0L header.

 

Would you think that the Rage V1/Hytech replica header would cause that same dip there? I'm asking because I have a very similar setup to this one (see sig) and have the same dip at the same RPM only bigger.

I have no knowledge on that header. If the first primary step is too large, or too long, midrange can suffer.

If you want to stick with your setup, the best idea is to have someone who actually makes header systems design you one.

 

I might go 2L next year but keeping the same head and boltons. You think it's possible that the big dip in the midrange will smoothen out with the bigger displacement?

Hey, I just put a set of pro 1's in and had it tuned. 185, and 191 open header on a diff dyno. If youre looking for cams, Me and another guy's dyno graph was overlayed and he had practically the same exact setup but using BC lll's and made alot more hp from around 7 to 7.6 than my pro 1's. Roughly 3-5 whp. Mine had a bit more bottom torque. Keep in mind that these motors were not tuned by the same ppl but mine did have an a/f that looked like gator teeth on the graph as well. dont know how it wld do w a retune but feel pretty confident w my tuner but not sure about the a/f graph. A wide band was used(on the second dyno run where the a/f was taken from, awa it was tuned on wide band of course), but when on the dyno, the wide band was not installed on the header but was put in the exhaust. Not running a cat, but still wld fig that wld have something to do w my gator teeth a/f. Gator
