My last post in this thread, just look at the numbers, really examine them and make your own judgement. I hope that maybe these will change and when HKS finally does release the cams that specific for the IX, There will 400WHP stock turbo IXs all over the place, even with out the EVO VIII cam I still believe in the near future we will be seeing a stock turbo IX hit 400WHP.

Congrats to the author of this thread, your car is bad ***, and believe me I envy you and every other EVO owner on this board.

 

But he said he was at 21psi on the before-tuning run, so where did that come from? We have to assume he had boost control, because he said there was NO CHANGE IN BOOST after the 300/270 run with the mods installed. There are just some details missing/skewed is all...

 

Why are the curves so far off on this graph? The Peak HP and TQ dont match the graph numbers. Hope this graph wasnt manipulated to make a false point.

Anyway - back to the thread. My original pull (with mods) did have an MBC set at 21psi. It also bleeds down to about 18psi. This was all confirmed by recording boost with the DEFI gauges. So, although the boost curve isnt exactly like stock, it's fairly close.

Thanks to everyone who understands it takes a look of work to do comparisons - and to show the results in the fairest way possible. Comparison of Pruven's dyno to TopSpeed's dyno is difficult and no way a 1 for 1 match. According to Doug @ TopSpeed - their dyno reads low.

What I will try to do is continue to test different cams as they come out. For now, we have an idea what the 272 does (or doesnt do, for those pessemists).

Maybe I'll try a 280 next.

 

For all the IX testing by Vishnu and Topspeed - this doesnt jive - if we were talking about torque!

But you mentioned HP. My IX made 30 more whp than a stock IX - according to the first graph. In line with what you mentioned.
But that's not what we are talking about - its all about the torque. For some reason, one that Shiv only knows - the unflashed ECU keeps the power in check.

 

The torque figures were in line with the HP figures. The TQ comes from the boost anyway. The reason why unflashed cars WITHOUT MBCs end up with low power even with I/E is because the ECU still has control of the boost and lowers it accordingly. With an MBC, the ECU no longer has control of boost, so it cannot adjust accordingly.

This isn't something that only Vishnu knows. Al has been pointing this out for a while, and this is why he even has a new version of his Dynoflash that includes a new boost hose so as to overcome the ECU's attempt to lower boost so far. I believe Precision Dyno has done something to the same effect as well, but they're not really advertising it. The IX ECU is smart, but with an MBC, it can't lower your power.

As for the Pruven sheet, you just weren't looking closely. The forced scaling wasn't on, so the TQ (delimiters on the right) line is not on the same scale as the HP line (delimiters on the left). If you look at the numbers on the left and right, then you'll understand. Regardless, though, you're right that we can't compare these 2 dynos directly, even though they are Dynojets. You were both using uncorrected numbers, though, AND if you dyno'd 270/270 stock, then I contend that the TopSpeed dyno does not read low. As I already mentioned, the stock IXs down here are all doing right around 250 (244whp low/254whp hig, and that's on 2 separate Dynojets. 270/270 is on the upper side of what a stock IX can show on any dyno.

What we REALLY NEED is ciphermonks graph overlayed with yours, because he put down 340whp/329wtq on 93oct with the stock cat on the TopSpeed dyno. His mods were BR DP, HKS HI-power CBE, MBC, and EcuTek. If we could overaly your two graphs with the same correction factors (both uncorrected and SAE), then we'd have an apples to apples comparison.

 

The purpose of a new boost hose is so that it could be equipped with a smaller diameter wastegate signal line restrictor. This allows the factory boost control solenoid to have more of an effect on boost pressures. Especially at high rpm where the factory boost control system, with the stock restrictor, can only support 15-16psi at 100% boost solenoid duty cycle.

I can't wait to see the dyno numbers when Hks releases the New Mivec controller and cam for the Evo9!!! I'm hoping for 400whp with this setup!!!That would real be nice!!! Nice numbers B.T.W!!!

 

Hell yea, man. I appreciate the love.

The car is really a blast to drive - and so civil when you arent getting into it. Mash the gas and all 4 tires light up and the car literally leaps forward. Especially with the launch control.

 

where is this comparison?

 

Just to update, because I know this thread caused a lot of controversy, Turbo Trix did a dyno pull with out HKS 280 Exhaust Cam and one with the HKS 280 Exhaust Cam and the results were surprising, they experienced a gain of 31WHP. That is very interesting, and I do hope that this is the case with a Cam for the IX. I'm sorry I brought controversy to this thread, but in my opinion I really didn't see any gains from the Cam, if two pulls were done comparing the car with and without Cam then perhaps we would not be in the situation. As far as this thread, I am still unsure of the gains. I hope there are further tests in the future of the VIII Cam on a IX. TT is working on a Intake Cam for the IX, and release date of HKS Cams is still up in the air.

 

link to thread?

 

this thread gives me a WET TIP

 

I'm glad some folks out there took the time to debate my thread. It's why this forums exists.

You may have already noticed - I also gained 31hp (well.. 31.14 to be exact) with the addition of the 272cam v. without. Granted, this wasnt done on the same car - but the IXs put down similar #'s among different cars.

I havent seen a IX with nearly identical HP and TQ numbers as mine - 380/380. I think its the cam helping.

 

C16 leaded is out of pump too. Does that make it pump gas

100octane is race gas.

Pump gas is 97,89,91,93 (and 94 used to be).

 

I told you HKS 272 on Exhaust side can put out good numbers with a tune
