Today, I got my RalliArt back from AMS. I had them perform Stage 0 & 1 and put in the Eibach springs. I am loving it. I wasn't sure what to expect, since, they mention that after Stage 1, the car will be more powerful than a stock Evo X. So, I drove it a bit aggressively and the car certainly responded well. The springs have made the ride a bit stiffer & I feel like the car handles better than before. With the Cat-back exhaust, its certainly roars instead of the normal purr.

Just one question for anyone who has already undergone Stage 1. I feel like before the car went to AMS, I could actually feel when the turbo kicks in. Now, I don't feel that. Is that normal result of Stage 1? I don't doubt what the folks at AMS have done, but just that I would like to know from others.

 

Almost forgot ... Does the car really have 305hp & 305lb of torque as AMS claims?

 

i assume that s the crank power?

 

I believe that 305 is crank hp and its like 285 or something at the wheels. That is what I wanted someone to verify.

 

It sounds like the HP could be at the wheels but the torque.. .with the SST, is mighty high even at the crank.

 

I can certainly live with that. I am planning to call up AMS tomm and ask them.

 

I doubt it's whp but it's still much better then stock IMHO.

 

if u take Stage 3 # and bring it to the "familiar" 300 whp and 300 wtq ... you can see the number shown on the site is at the Crank and they account 17% for drivetrain loss..

so if u take the Stage 1 # and x0.83, you will get what you *should* be getting at the wheel..

meaning 253whp/253wtq...

 

Where did you read the part with the 17% power loss on the AMS site? Apparently, I missed it when I was reading the details about the Stages.

 

pretty much hes saying is that the number you see is at the engine and then minus 17% loss is to your wheel output correct me if im wrong anyone but i sometimes have trouble explain it ... AHHH

 

aah ... i get it now (being a n00b ) ... Damn, I was hoping that whp would be a lot higher than 252 after spending all the $$. Well, at least, I am now ready for Stage 2 for next year ... or following ... or whenever the wife approves.

Is 17% always the power loss percentage or does that depend on certain parts? When i was leaving AMS yesterday, the rep explained to me that I should be getting around 280whp. I didn't put the car on the dyno so I'll have to approximate my gains.

 

Pwer loss depends on the drivetrain. We experience more loss due to the awd setup. 17%-18% is about average for our cars. FWD and RWD is usually much lower.

In terms of power, you would have to see the dyno result to be sure one way or another.

AMS claims 40whp increase over stock with just their tune. The stage 1 (vs stage 0) doesn't add much power, it's mostly small battery, CAI, and exhaust. So 252whp seems right to me.

 

im not saying its written anywhere.. it was a *pure guess*

because their stage 3 is the Evo X turbo swap... which ppl usually get 300-320 whp (DEPENDING on which Dyno ure on and who actually tune it...)

so you can "deduct" the drivetrain loss based on that ratio...
either way... a "whp/wtq" number is only relevant if you have ur baseline #...

most Stock RA has a baseline of 190-200 whp... (same thing here ... if u take 200 whp/237 at the crank claim by Mitsu... you get about 14% loss)

drivetrain loss depends on many factor..

 

17% to 20% is standard, and those are purely crank numbers listed on the site.

initial you mention 14% is the loss for 237 to 200, its actually 18.5 %, but 237 to 190 a number you quoted as low end base numbers is which is 24%

I agree, many factors contribute, but on our specific platform, 17-20% is a good range to use.

 

18.5 or 14, as long u can do cross product.. ull get the number uwant to know..
its an estimate anyway...

@komilp13
252whp is already alot .. considering u added 25% more power to ur car.. + im sure with the boost pill ur boost will hold alil longer..
