Here is my attempt at digitizing the charts - it didn't come out all that well, but you can at least get some idea of what the curves look like.

Stock base run



Pulley, intake, throttle body, header, Magnaflow overlayed on the stock base curves



The above configuration with the Superchips ECU overlayed on the run without the ECU mod



These are average plots - a pretty good representation of some of what's going on. I have about 20 dyno plots, so I just pulled some to see if this method of posting them would work. I'll keep working on a better method to display them here.

Let me know if you have any questions.

Nice, but appears on the last dyno you are seeing the same waveness i was talking about.. in the upper rpms...4000+ any ideas' why?

 

It's hard to see, but it really isn't all that wavy - it's more where the two curves are overlapping. If you loook at the second picture with the stock and pulley etc. comparison, you can see that there really isn't any wavyness.

 

Randy,
I am glad I decided to back out of our 'adventure' when I
did. I'm having sugery on my eye on 4/14 and have been
advised by a neurologist to quit racing. I have a disk problem
in my neck and start physical therapy on Monday. But I refuse
to stop riding motorcycles until they pry the handlebar from my
cold, dead fingers.

 

i apologies its 5000+ and yours doesnt look quite as wavy as mine, i know my TA had a very smooth curve, but its Natrully aspirated, maybe thats some of the wavyness...

take a look at mine maybe you can see what im talking about...

Randy you have been the source for us hp seeking mcs owners.The data at mcshp is great but it's a collection of untested gains from the manufactures claims.I've done the Rogue air intake and the quicksilver exhaust;
but any further hp mods impact my warrenty,so I want to be very certain of the hp gains.I'd love to see real hp gains for each item individually.Does this data exist anywhere;or will we continue to be at the mercy of manufacturer and vendor undocumented claims?

 

Mike,

I've done most of that testing, but it would take an AWFUL lot to sort through it and post it all. You can see the results of accurate testing on my website. Most of what I have there is from my testing - although there are a few things I still have to correct.

With your set-up, you are looking at around a 13 horsepower increase.

Give me a call if you have any other questions.

Randy

 

I would quess your estimate of about a 13 hp gain is about right.But you've agreed with my comment of undocumented manufactures claims.I realize hp gains aren't cumulative:but quicksilver claims 13 to 14 hp gain from the exhaust alone,Rogue claims 9.3.We miniacs are spending a great deal of time and money;should we just reduce manufacturer's gains by half.I love the car and am happy with the mods,but I think the manufactures and vendors should be held to a true standard.

 

Agreed. One of the problems is how variable testing can be - it is very easy to make inflated numbers on a dyno (something we spent a day looking at on the dyno).

I have seen most, if not all claims deteriorate in an honest testing condition. Rosue is actually pretty close with the intake alone - I have seen one warm dyno run of 9 hp, but it averages around 7. When you start doing multiple mods, the numbers aren't additive. What I mean by that is the QS exhaust may make 10hp, and the Rogue makes 7, but when you put them together you only get around 13 instead of 17.

Again, if you have any questions about what products really do in a controlled environment, feel free to contact me.

Randy - Have you tested the intake + pulley + chip only? I know that you didn't get a great result with the chip on top of all your other mods, but a lot of us just have the intake and pulley. Given that several chip makers claim the above above combination is good for 200HP at the crank, I'd like to see a dyno run and wheel HP for that combination; it may be worthwhile if a person doesn't have the throttle body, exhaust and header like you.

Thanks!

 

evotech has run their chip, with the pulley and intake (last week). they got 179 hp and 156 ft-lbs. the car rev's to 7500 as well. (their baseline: same car, with chip and intake was 153 hp; with out chip, but with intake was 147 hp) their numbers seem what I would expect, using a dynojet and reading wheel hp.

they also exhibited the 6200 rpm torque fall off, where the curve takes an obvious change affecting what the "projected" torque would be by maybe 5-10%. My guess is that this is a detonation correction to the timing. My car showed the exact thing, (without the chip), Helix dyno.

I also think it is their standard chip, not something cooked up for the pulley mod.

As far as absolute value, 179 hp is one of the highest readings we have seen, and if the detonation, or whatever was not there, it might go up another 10hp. that would be pretty close to 190 at the wheels.

by the way, I just completed the aquamist water injection install, my attempt to thwart detonation, and will report. It is set up to start squirting at >10psi.

 

The highest I've seen on my car is 186.1

It sounds like the pulley made most of that difference as well. If you take the typical gain of 16 or so horsepower, add it to the 153 they had before the pulley, you come up with 169. That means the chip is worth 10 horsepower - and I don't know if the run was done cold in comparison (which could make a 10 hp difference on its own).

The trend is starting to say that 10 hp may be the ceiling for ECU tuning. What I am looking forward to is working directly with APR. They will tell me exactly what can be had from ECU tuning without false marketing claims. So far we've seen 6 hp form the Superchips software and 10?hp from EVOTech (not my test). If APR can read the Siemens, we will know what the possibilities really are.

Sounds great to me too!

 

As soon as I get the ECU package I'm happy with, I will do that test. It'll probably be on DiD's car . We'll just have to pull off his Magnaflow and put that anchor of a stock system back on at the dyno (he joined the Dark Side and got the Magnaflow ).

 

I wonder if there is a way to put you DYNO sheets into Excel or soemthing. The pics are fine, but it would be easier, I think.
