Well, I just got off the phone with Rob from NeedsWings. He was on his way back from the Dyno and was pretty excited by what the results were.

I don't have the exact specifics, but just during the brief conversation we had it would seem he has a STRONG car in stock form to begin with, but none the less, here's what he told me. I'm sure he will be able to elaborate more once he has a chance to analyze all the info.

DynoJet Roller:

Best Run 100% Stock = Exactly 300 WHP

Best Run With his intake = 330 WHP

Consistent WHP with his intake = 322

By the way, this dyno was done while hooked up to a StarTech MB diagnostic Laptop that allowed the 5,000 RPM cutoff to be cleared for the runs. These runs, I assume were all the way up to 6,000 RPM. So, that seems about right, since most seem to be in the 280 ish range at 5,000, and peak power doesn't happen till 6,000 RPM. Mine came in today, and I'll be up at dawn installing it.

 

automatics don't have the dyno cut out, it's only the 6 speed cars that have this issue.

pretty impressive dyno, but I really don't trust them anymore, after seeing how inaccurate they can be from differing manufactures. Usually a stock srt6 is in the 250 hp range, maybe a previous owner had the ecu flashed?

 

Always the optimist aren't you... Either way, even if a Dyno isn't calibrated properly, an increase of that much is still significant. Even if it is off a little, it puts out more than any other Tuner Intake out there for 1/3 the price.

I'll let Rob tell the tail in detail, as I don't have all the facts...

 

I would agree 100% with those dyno figures. My car has gotten faster yet which I think is due to the ECU adjusting for the increased flow. My times prove it as well.

I would find it hard to believe this car dynos at 250 HP. My Z06 dynoed at 365 stock and was around the same weight. I would think if it really is 100% MB engine with the 349 HP then it would be right at 300 stock.

 

We have several dyno graphs of stock srt6's on the forum here, and they usually loose about 60 hp by the time it hits the wheels. Isn't stock power at 310 fwhp -.20% drag (60 hp) = 250 whp, so your Z06 is probably laying down 292 whp.

If his little intake pipe brings power up that high, I have to say that I'm impressed!

 

Is there a picture of this intake anywhere?

 

Yes. It is under a couple of threads: AFIAK . . . and Sneak Peek.

What? The SRT6 reportedly has 330 hp/310 tq. Truthfully, it probably has 349 hp/332 tq.
I have seen some SRT6 dynos at ~ 290-300 rwhp. Which makes sense. 20% power loss to the wheels: 349 - 69.8 (the 20%) = 279.2 rwhp.
I read that it is usually a ~ 16% loss. If that were the case, the SRT6s would be putting down ~ 293.16.

 

Couldn't find any picture, can you post a link?

 

Here you go.

Thanks. Looks good.

 

hello, yes we hit the rollers tonight playing with the intake, stock pulls were 295, 296, 300, with new intake swapped in we made 319, 320, 321, 322, 330, we also picked up 20 some ft /lbs of torque going from 28x to 307.

we also played with the octane settings in the ecu, tried base, 89, and 93 settings, 89 setting kept the hp around 280, base and 93 were consistent in the 300 neighborhood, so not gains there, sorry i was hoping to pick up power by turning the ecu cal to 93 octane but it did not make a difference over the "base" setting. all the pulls for the before/after intake pulls were done in the "base" setting.

i'll post the dyno graphs up hopefully later tonight, its been a long day so maybe tomorrow but i'll try for tonight if i can get the scanner dug out of the basement and hooked up, got a couple cell phone vids also, i'll have to get them onto the computer and se if the sound came out good enough to hear the supercharger whine with the new intake on the car. overall we are very pleased with the results and these will go on sale on our website as soon as we get our results back from our test fitters. thanks, rob www.needswings.com

 

Dude, seriously, if you have nothing constructive to add to this discussion then don't bother. And FYI the car is rated at 330 FWHP and it is actually 349 which is the same as the C32/SLK32, that has been confirmed. You don't even own a 6, why are you here?

I haven't dynoed, but with time slips, Math and Physics, taking into account for drag, weight, gear ratios etc... I have estimated that mine puts down between 280-290 WHP. Now account for the 20% drivetrain loss, that equals 350 ish FWHP. Math, Physics and Time slips don't lie.

 

That is correct. I ran 13.2@105 stock and then with the intake I ran 12.9@107. I think the car has gotten even FASTER since my trackday. My Z06 was rated at 405 HP and dynoed in the mid 360's. It ran a 12.6@113 stock.

Maxwell anyone who knows anything about Z06's know that they dyno in the 350-370 range stock. I don't know where you get 290 from...maybe that's on 6 cylinders...it would be hard to believe the SRT loses 100 HP on a dyno...not even AWD cars lose anywhere near that much.

You don't think intake can add 20 whp? Go over to the Mustang Cobra site and see what a good intake can do for those cars...

With a blower on the motor it's easy to assume the more air the more ponys.

 

Here you go, I took these about 30 minutes ago. Keep in mind this one isn't finished, its a test prototype. The production ones will be Powdercoated Silver to Match the Engine Cover.

 

Easy bolt-on HP with no worries. Sounds like a winner to me!

also

FFLores dynoed 289 stock for reference to WHP rating debate.

Here's some more. I'll take some on the car tomorrow.

 

Awesome numbers...

Are you still planning to do a 'intro price' for forum members?

Thanks Powa, for the link to reality. Now be gone troll... (not powa).

 

I'm looking to get a custom dyno tune done with my ASP pulley installed...is the dyno you went to capable of this?

 

Ha you just read my mind. I was thinking about what kind of gains we could see with the intake, pulley upgrade and a tune. I guess you are our #1 test pilot.
