Re: Dave's Evo X Build/The Life of Dave blog
I'm with hughes, there's better ways to spend the money...I think that golden donkey manifold looks like shyte compared to the stock X mani....unless someone shows some crazy awesome dyno numbers from it and then like 10 more people do to I officially give it a 'meh.'
MAP Rev3, mil.spec TB, aluminum driveshaft, and some misc weight savings would be a better investment...and less impactful on teh entire setup. |
Re: Dave's Evo X Build/The Life of Dave blog
Small brakes is a terrible idea.
So is changing the mani/turbo etc. Touch stuff you haven't already. |
Re: Dave's Evo X Build/The Life of Dave blog
I vote two piece rotors, alum driveshaft, and other rotational weight mods.
|
Re: Dave's Evo X Build/The Life of Dave blog
Dave,
Don't make me have to slap you in the nuts... Seriously let's try to drive this thing this next summer. Also, you forgot the most important mod to to invest in... the driver mod. Sincerely, Shawn |
Re: Dave's Evo X Build/The Life of Dave blog
I agree. just drive the car and stop modding it.
|
Re: Dave's Evo X Build/The Life of Dave blog
I say drop some weight off it too. Makes it more reliable and faster, win-win!

Re: Dave's Evo X Build/The Life of Dave blog
Any actual dyno results showing a power gain?
I know dsm's usually picked up some decent power with a SMIM. If there are proven results and you got the money laying around I say go for it! If no results don't be the test dummy and wait it out, intake manifolds can be swapped out pretty quickly so there wouldn't be much down time besides maybe modifying your upper intercooler pipe. Light weight stuff would help you go faster too as others have stated though. |
Re: Dave's Evo X Build/The Life of Dave blog
Ok, seems most people agree on the rotational weight stuff, that is easy and safe I think.
I was just toying with the idea of a full t3 kit but it seems like most people agree to stick with the EF4 haha. Zero results from that intake mani, so I will stick with the idea of doing the MAP rev 3 and milspec 64mm TB, those are proven. Shawn, driver mod is #1 on my list and in order to do that I do need the car working so I guess you win, no more "big upgrades". Intake mani and tb I'll do in spring before I pull the car out of storage. Seats are also on the list this year though. People have dropped almost 70 lbs from doing lightweight seats. Then after that I'll just workout more to lose some more weight maybe :) |
Re: Dave's Evo X Build/The Life of Dave blog
If you can pull just 100lbs out of the car, it will be like gaining 15-20whp at your power level/vehicle weight.
Shawn, no driver mod needed. It's an X. :) |

Re: Dave's Evo X Build/The Life of Dave blog
I just saw Ryan Gates post on FB that he now has his X down to 2550 race weight...jealous, that is like 1000lbs less than mine, I hope to get mine in the 3100 area so about 300-400 lbs less.
I haz no driver skills so I guess its good I have the X. |
Re: Dave's Evo X Build/The Life of Dave blog
Losing that much weight gets expensive.

From previous experience trying to save weight cheap, unless you're going for a full out race car leave the creature comforts, it isn't worth it in a street/track car |
Re: Dave's Evo X Build/The Life of Dave blog
Things I love:
-factory Recaros with airbags -cruise control -Bluetooth -Sirius radio -extra sound deadening -auto climate control w/A/C -navi -SAWC I'll keep my weight :) The only places I would consider losing it are with a lightweight driveshaft, BBS wheels, and 2-piece brake rotors. |
Re: Dave's Evo X Build/The Life of Dave blog

Something to consider, if you take out too many of the creature comforts, if/when you ever plan to sell, you just made your target market that much smaller. People like myself and most others as we all age will want them. |

So far all I have done for weight that would affect anything really was strip my trunk out, which did get rid of the sub. But I can put all that back in. The only thing I might do would be going to lightweight seats which could potentially bother another buyer but i will keep the stock ones. |
Re: Dave's Evo X Build/The Life of Dave blog
Buy my old IX, it's getting passed around down here like an underage sorority chick.

Re: Dave's Evo X Build/The Life of Dave blog
^lol, that would be awesome.
Murlo, go buy another now you have a year or so of internet experience behind you! |
Re: Dave's Evo X Build/The Life of Dave blog
I should have some new parts today that I will post up pics of when I get them for the Evo, nothing huge but some needed stuff in my mind to polish off the setup. Still too cold to install them in my non heated garage, but can't wait for it to warm up to start wrenching again!
On another note, this was just posted on Evoxforums. http://www.evoxforums.com/forums/att...1&d=1359695170 Twinscroll t4 ETS kit, 6466 turbo, ~1.0AR. Seriously, this spools identical to mine, faster really, makes almost 700whp on 26psi! This on 35psi would be almost 800whp! I know what I am doing if I upgrade....might have to sell my new gun for this shit! |
Re: Dave's Evo X Build/The Life of Dave blog
All the cool kids run a 6466...
|
Re: Dave's Evo X Build/The Life of Dave blog
its never too late to buy another 8/9
|
Re: Dave's Evo X Build/The Life of Dave blog
Leave it alone!!!
And if you do choose to sell ur gun, make sure I get my acog back. :) |
Re: Dave's Evo X Build/The Life of Dave blog
That's a fucking beast mode powerband, Dave.
What size motor was that on? |

What is different on your car that would allow you to reach the same boost level at less RPM than that one? Edit: Ah just saw in your sig you are 2.2L. |

I am not really trying to "keep up" with anyone at all. Just looking at the next step for improving my car. This is a slam dunk if I really want the whole big time turbo setup. But realistically its prolly not going to happen, not this year. Honestly, I just thought it was an AWESOME setup/powerband that got me giddy and wanted to share with everyone. Didn't seem worth making a whole thread for it. I have enough work on my current setup before I move up still. |
Re: Dave's Evo X Build/The Life of Dave blog
That twin scroll 6466 looks nice. I wonder if the 1.0 A/R exhaust housing would choke it at all at higher boost levels.
One thing though, even though it is fully spooled at 4000RPMs, it doesn't look like the motor is able able to due much with the air since the HP and TQ at 4000RPMs are nothing crazy even though it's spooled up. |
Re: Dave's Evo X Build/The Life of Dave blog
don't forget to differentiate 'spool' vs 'boost threshold' ....I'm sure it might have a decent boost threshold (4000rpm) but stomping on the gas at 4000rpm will probably be a pretty different experience in your car with the ef4 vs that one.

Re: Dave's Evo X Build/The Life of Dave blog
2.7L, do it!

Re: Dave's Evo X Build/The Life of Dave blog
Dont change your set up. Leave the poor car alone and just drive it. If you want to throw money at something. Join halon cornfed and I in build a monster dsm for the track and the street.

Guess I'm used to seeing the TQ line at least somewhat resemble the boost line, so this doesn't compute in my head. Usually I'm used to seeing when the boost line starts rising rapidly, so does the TQ line. Then when full boost is reached and the boost line tapers/flattens out, the TQ line isn't to far behind. I think if I was going after a very fast spooling setup, and I managed to get a setup to spool as quickly as that one does, just to find out on the dyno that even though it spools fast it doesn't matter... Random evo dyno charts as an example of what makes sense in my head: http://farm9.staticflickr.com/8431/7...9fbc93b4_o.jpg http://www.maperformance.com/img/EVO/evo-dyno.jpg http://i8.photobucket.com/albums/a48...Low_Boost1.jpg |
Re: Dave's Evo X Build/The Life of Dave blog
That engine is not efficient at the lower RPM & flow. This could be for many reasons, extremely ported head, really big cams, etc. You can tell it was built for high RPM as the power doesn't fall off at all up top.

People always get all hyped about variable vane turbos, spool valves, or other tricks, so they can have the dream 1000whp turbo that spools at 1500rpms. But even if you get that to happen, it doesn't mean the car will make any power. That dyno chart seems to be a great example. It obviously hits full spool well before it starts making good power. That's not a bad thing, since it's probably decently responsive or at respooling at higher RPMs for a turbo that size. Maybe that Evo has cams and and intake manifold that give up low/mid range power for top end. But anyways... Here is a helpful way to think about it. First off, a turbo is not like a roots style/positive displacement supercharger. It is not designed to make boost by stacking air and holding it it. A turbo makes boost inside the compressor housing and sends the air on it's way to the intercooler, engine, etc. So when you put a big turbo on a small motor and you get that turbo to spool really fast what happens? You get compressor surge. What is compressor surge? It is when the turbo puts out more air than the engine can take in and the air starts backing up and eventually backs all the way up to the turbo itself which causes the comp wheel to drastically slow down or stop(this is bad and very hard on a turbo). Compressor surge goes away as you go up in the RPMs because engine can finally use all that air. So what does an anti-surge/port shroud compressor housing do? It lets that excess air flow back out into the intake pipe in front of the turbo, so you are essentially just wasting some of the boost/air you worked so hard to build. It is also better to run a non-anti surge compressor housing if you don't need one, they usually make a little better power. In other words, you can't have your cake and eat it too. |
Re: Dave's Evo X Build/The Life of Dave blog
So it's an engine thing, not a turbo thing, is what you're saying? The engine is full more or less (air-wise), it can't use or do anything more with any more air at that rpm range.
So with that being said, really any turbo setup would not make more power at that RPM range either, whether it be a stock turbo, EF2, etc. Because this is purely an engine thing, and the PTE is already packing it as full as it can get with air. |

Re: Dave's Evo X Build/The Life of Dave blog
That is awesome, I say do it.
Is there anyone local making good power on a 6466? I haven't seen one outpower a 6266. |
Re: Dave's Evo X Build/The Life of Dave blog
You can get a 6266 or 6766 for half the cost of a 6466, so it's probably not going to be that commonly used.
