I understand that dynos measure change and it's not the end all number of performance.

Am I using all the power? Not daily, of course, but there will be a few track days that I'm certain to attend later on. I enjoy super sport and a secluded WV mountain every so often though.

Unfortunately, e85 is out of the question in my area, the nearest station is 20 miles away... which would just be an awful purchase lol. I was considering fuel upgrades, but I didn't get to see where my IDC sat when he was tuning.

When I spoke to the tuner about the figure, he simply stated my next mod/s to make power would be a tubular manifold and a small GTX28 turbo, or something of equivalent size, and I know that would require fuel modification.

This car is supposed to be a quick DD with the occasional autox run and mountain fun. I have a track dedicated car already. With the mods done, I expected more change, not only in numerical performance, but in the butt dyno as well. I just feel underwhelmed, for lack of better terms.

 

Feeling underwhelmed is understandable in a X imo, especially with SST. I put my fastest times at HPDEs in my X MR for a reason. It was because the car was doing MOST of the work for me. I wasn't rev matching a clutch, I wasn't having to correct every corner, I didn't even have to switch feet as I can left foot brake.

Turn off traction control (have you tried off-off?), put it in manual mode and push the car. I know the car has the potential to hit 150~ on the right tracks, and scream around corners. One of the reasons I love the CZ4A is the cornering ability, I get adrenaline from hitting the corners hard.

If you're still underwhelmed, either you need a more raw feeling car or have outgrown the tuned stock potential -- time for a turbo.

 

off-off in manual mode is generally how I drive it. the less electronics messing around with the way I drive, the better imo.

A more raw car would be amazing, but out of the question. (read: my wife will shoot me after spending all this money on the evo to get rid of it)

I have no problem with a turbo upgrade, but the potential for things to start breaking freaks me out. i don't know this engine well enough to know how it performs under excessive stress, even with a good tune. Let alone the SST.

I've done my research, read up, but that doesn't dictate this particular evo's ability to not crap out under more power. I think that's what intimidates me the most to keep pushing the envelope. My STi (i know, apples to oranges) was a catastrophic failure after catastrophic failure. At least once due to me learning how to tune. Frankly, I don't want this to turn into another money pit just to keep it on the road.

I know this is all my choice, and what I want to do, and what risk I'm willing to assume, but damn.

 

Instead of getting caught up in the endless pursuit for more hp, maybe just get some light weight wheels (Volk RE30 look great on the X) and better tires. Shedding unsprung weight and adding grip will let you do more with the hp you have.

 

Truth!!

 

agreed on the weight savings for sure. I would like to pick up a set of lighter weight wheels, but I haven't done enough research to warrant a purchase, especially of that magnitude.

I have swapped out to RE-11's though, it's a great tire.


But it's posted above. stock puts out 230, I'll modify the OP

 

If you do decide to pull the trigger on a turbo, here is a member selling the new CBRD 7163 kit for the X https://www.evolutionm.net/forums/sa...-manifold.html

Its a nice bit of kit and he seems like a motivated seller. http://www.cbrdspeedfactory.com/cbrd...b-x-turbo-kit/

 

looks like it was sold, that was a hell of a price too.

 

MHI TF06-18K from Forced Performance would make you happy.

 

As to the weight savings, can't go wrong with RPf1s, ditching the spare (I'd rather get towed than drive on that thing), and coils.

As far as the dependability of the 4B11T, it can take a lot. And by a lot I mean another 200whp, 150wtq. ETS, Ryan Gates, AMS, English Racing have had success pushing over the 600 mark, I don't think that was sustainable though. Either way, you don't have to worry about adding another 100whp, you'll be fine there. What I'd be more worried about is the transmission. If you go beyond a stock framed turbo, you're going to need new clutches and an aftermarket SST cooler.

 

Ive been on 400whp+ for 7 months now and drag raced one my SST still feels nice. Make sure the torque stays under 350 or close and you wont need to replace the packs right away

 

I'm curious if my current setup is a bit restrictive. being a subie guy, I've come to love perrin equipment, but I just don't know about that downpipe configuration. I'm also not a big fan of megan products at all, but I installed it in the interim to free up a little bit before I started doing a build.

I think I should go with a straight test pipe option, and just swap the cat on for emissions purposes when necessary. I'm just not certain what, if any, gains I would expect for spending another 6-700 on exhaust components.

As far as a bigger turbo option, I've been looking at ETS mostly, I REALLY like the CBRD stuff as well. Seeing how I have no personal experience with either, it's going to be a crap shoot, but both seem like quality products. But a tubular manifold and fueling components will be in the mix as well.

When it comes to weight savings, other than wheels, I'm looking at lighter braking options as well. I think this may be too overboard for a DD, but whatever. 99% of the things I'm trying to accomplish can be installed over a weekend with some beer

Anyway, thanks to everyone for your input! I haven't really shown any gratitude, but I honestly appreciate each one of you!

 

Did you find out what a stock 10 puts down on that dyno yet?

 

it's in the OP

 

Ive ran your exhaust setup. The catback is very unrestrictive. The downpipe doesnt add much beyond having a hfc. It gains a bit over stock, but obviously not like a test pipe would. The downpipe adds nothing as it doesnt have the o2 housing. You arent going to get much more without doing a test pipe. I stopped running test pipes for many reasons. The 5-10hp gain wasnt worth smelling gas fumes and eyes burning to me. Plus i like to be nice to other people on the roads.

Turbos, it is going to be what your goals are. ETS makes big turbos. They are going to lag a bit more than CBRDs stick frame, but they will put out more power. I have a lot more experience with ETS but both are great options.
