I looked at the base lancer and it has 148hp the RA has 237hp so is it 89hp... Does not seem right

 

What doesn't seem right? Yes, they are rated at 237 and put down about 190-195 to the wheels on an AWD dyno.

For reference on the same dyno:

Stock 03/04 evo = 190-210whp

Stock 05 evo = 210-215whp

Stock 06 evo = 220-230whp

Stock 08 evo = 215-230whp

 

does the stock turbo on a ralliart produce 89 horsepower

 

It's more than just the turbo that produces that difference. The whole engine is different from the NA version, and the ECU programming is different.

With just a tune you can make 40 wheel horsepower more than stock.

 

hmmm i dont think im saying this right... if the RA has 237hp and i put a turbo that adds 100hp the end result should not be 337hp because the original turbo has a certain amount of hp that its adding.

PS This is what im trying to figure out now but im going cross eyed... i dont have all the # i need as well

A rough way to compare turbos is to look at how much air they flow. This is usually reported in lb/min

"As a very general rule, turbocharged gasoline engines will generate 9.5-10.5 horsepower (as measured at the flywheel) for each lb/min of airflow. So, an engine with a target peak horsepower of 400 Hp will require 36-44 lb/min of airflow to achieve that target. This is just a rough first approximation to help narrow the turbo selection options."

The Garrett link is too general for you IMO.

Ask yourself, am i staying with a stock frame (evo x) turbo or changing it.

Assuming you stay stock frame, it will limit your number of turbo options. Step up to OEM evo X turbo or FP 18k?

Just going off of OP's line of questions, it sounds like he needs that baseline level of knowledge of how turbochargers function. There is application specific information for days on all the available turbochargers for the platform if he searches. Without that baseline knowledge though he isn't really going to be able to put that information into context.

OP, its not like a video game where you add a turbo and get X power. The whole power train functions as a system to pump air, you're power is constrained by the most restrictive part of that system. Simply adding a different turbo will not result in a direct increase in HP. As Razor said there are many other parts of the system that need to be accounted for when improving the air pumping capability of the whole system. As he explained even the stock turbo isn't the restriction in stock form. With just a tune (Software recalibration) the engine picks up significant power.

 

I really do appreciate all the advice, im trying to learn what im doing because believe it or not nobody in phoenix knows about ralliarts. i went personally to all the shops, the 2 of the that have worked on them were discouraging the one that does cobb tuning has a bad rep (but recommended by the company) and the other one uses the other program have done 2 but the last time they did one was 5 years ago and they wont tell me if they can work in my car...

I now know that maximum hp im aiming for is 350hp and very likely going to put the FP 18k. Cobb has some good tutorials on their site that helped me learn this mess a bit faster

 

The proven part path for an easy 350whp on an RA:

- MHI 18k or Garrett GTX3071R or Blouch Dominator 1.0XT (recommend MHI 18k)
- AMS upper IC pipe or equivalent
- AMS downpipe or equivalent
- AMS intake or equivalent
- ETS FMIC or equivalent
- ID1kcc injectors
- Aeromotive drop-in fuelpump
- Testpipe or highflow cat
- Whatever catback you want (recommend Magnaflow)
- ECU tune by somebody that knows how to tune an SST equipped Mitsubishi

300whp on the cheap:

- Evo X OEM Turbo
- Evo X OEM upper intercooler pipe
- Evo X OEM FMIC
- AMS intake or equivalent
- Testpipe or highflow cat
- ECU tune by somebody that knows how to tune an SST equipped Mitsubishi
