TTP-Engineering Tunes the 2009 Ralliart 4b11
You have three numbers, a minimum, a maximum and an average. On the dyno sheet present in this thread, it says maximum HP thus I compared maximum to maximum. If I compared the average for the Evo to the one value found here the Ralliart has more power than a stock Evo which we know to be wrong. No one is dissing the dyno or the results, we're just putting it into perspective before people start proclaiming that the Ralliart was underrated and actually has more power than an Evo stock.

Yeah stock Evos and STis make about 220 WHP around here on most "heartbreaker" dynos. We're amazed when people pass the 300 WHP mark and truly astonished when they break 400 WHP.

For comparison, if we take the max HP produced by a stock GSR, you have 256 WTQ and 252 WHP. Clearly this is a high reading dyno when we only see a ~30 HP difference between crank and wheel HP on a 291 HP vehicle. The Ralliart isn't underrated, the dyno is just very nice.
While it is true that the MR has launch control, it could be like the launch control in the GTR, ie. if you use it, you're on your own.
Edit: Sorry, I have the WTQ and WHP values reversed.

That's what he's saying. He'll agree with the boost number and every other parameter, but because the dyno number obtained doesn't follow his logic it's obviously high reading. In fact the higher boost reading actually works in his favor, that way he can tell everyone the car is almost completely maxed out. All dynos will be high reading until someone posts 170whp running on three cylinders, and the childish "I told ya so" stuff will pop up again.

Your opinion. You cringe at the fact it could be underrated so you say otherwise. Three dynos have given all similiar numbers, yet they're all "high" reading. I'm willing to bet you're waiting for the lowest possible dyno numbers to agree with. The SST has been pushed past 330wtq which is more then AutoBlog's 330 crank tq as its limit, but i'm sure you still believe AutoBlog, right?
This is exactly why I absolutely hate dyno numbers, 99% of people can't read them worth a damn. I don't care about the number, I care about how it compares to other cars (ie. reference points). The Ralliart could dyno 140 WHP but if an Evo dynos 170 WHP, the Ralliart is pretty close to the stated value of 237 crank HP.
What does 330 WTQ mean in that context? You need a reference point. I don't see why this is a difficult concept.
No I'm saying that the numbers are simply high. Dynos are not accurate and inaccurate, they are simply a tool. The value is arbitrary, what's important is how it compares to the reference values.

Ralliart
Crank HP 237
TTP WHP 220
TTP WHP/ Crank HP ratio- 0.928
Evo
Crank HP- 291
TTP WHP- 252
TTP WHP/Crank HP ratio- 0.865
If we make the false assumption that two cars will have identical powertrain loses despite having different powertrains, we can increase the Ralliart to 250 crank HP. However, this doesn't line up with the performance numbers. Moreover, that is bad logic.
Edit: Look at the WTQ numbers as well. Are we to believe that the Ralliart only has 14 less WTQ than the Evo (which is rated at 300 ft-lbs vs. 253 ft-lbs for the Ralliart)?

I'm just shocked that the RA is running 19 PSI, that doesn't give you much room to expand. It also doesn't translate for me, a WRX running 14ish PSI from a TD04-13T makes 224 HP (2.0 L model) yet a Ralliart running 19 PSI with a larger turbo makes about the same power? Something doesn't add up.
ps i know its spelt apples and
ps. apples and cannot
