What i should do next for my car so i can run mid to high 11s on the stock turbo, but i also want this to be a street car. Its my daily driver. I have a evo 9 and i have been searching around here for awhile to see what i should do and most of the stuff i read is to add a methanol injection but i do not want to do that. This is what im getting so far

Air intake
Blow off valve(given to me)
Tbe
cams prob 272/272
exedy twin disk clutch
mbc(21-22lbs of boost)
reflash
fuel pump

What else should i do to make my car run 11s?

 

That should be 11's, but you don't need a lot of that stuff.

On an Evo IX you don't need a BOV the stock one is good just like the VIII JDM valve, and you don't need a fuel pump because the IX's have an upgraded on stock.

You'll need a custom tune, and RACE GAS. The IX's have revised and improved cooling passages in the block/head that make the engine more resistent to knock, so TURN UP THAT BOOST, 22 spi is pathetic even on pump for a IX.

w/o alky/meth or racegas there is no 11 second 1/4 mile run for you.

Other then that, you're good to go.

 

Yea i know i do not need a bov but it was given to mu otherwise i would not have gotten one, but i thought that you did need a fuel pump on the IX. I heard that it is better than the VIII but still not that great, but i could be wrong. Thanks for the info

 

Yeah you shoudl already be into the 11's with that setup. prolly due to the BOV you have on is why your not getting there. Do a few things.

Up the boost and use race fuel.
I dont knwo why you got a exedy twin disc for such a small setup. thats overkill mang
Take the BOV off and put the stock 9 one back on
Also cams arent out yet and when they do come out I think they will be 264's not 272's.
Also get a custom flash from dynoflash.

 

Exedy is not overkill for this setup, it is crutial w/ an 11 second goal in mind. Ask most-wanted.

Your fuel pump is fine, and your BOV i'm sure is fine.

He is right about the cams though, but i do know that TurboTrix already has something in the works, i think an intake cam or something. But it is pretty unbeneficial, and Most-Wanted ran mid 11's w/ pretty much intake, exhaust, racegas, and a tune.

 

Dude you ask a vendor for technical questions? Whats wrong with you they are just trying to sell you stuff. If you dont beleive me ask warr or Buschur. They will tell you its overkill for simple bolt ons on the stock turbo/IC/and engine.

The only time you need a twin disc is you are are pushing over 500awhp. And I am certain hes not going tp be pushing that on those mods.

 

It doesn't matter if someone gave you a BOV - that's no reason to use it. Use your stocker and sell the other one. If you already have the fuel pump, then use it. The cams are not available yet, unless you want to pay $900 to TurboTrix. We haven't seen much empirical evidence on those cams from customer cars, so I'd wait a bit. GSC is also releasing their IX 280 cams in a few weeks, but they will be less than $600.

If you don't want to use alky, then you'll need race gas to be in the mid-11s. Otherwise, the best you can hope for on pump gas daily driven is a high 11, and that's if you are a good driver.

 

So for the clutch now what should i got with a single disk? Im lookin for somethin that would give the stock feel maybe a lil stiffer, but hold my power for everyday driving. Also for the boost what can i turn up the boost when running on pump gas, and drive around as a daily driver.

 

the exedy twin is fine dont listen to skil, you'll thank yourself in the long run. Also not to hijack or anything but what octane was most wanted running for the 11.5 pass? I'm guessing 110 leaded?

 

On C16 race gas on our dyno the most you can push out is about 330-340whp on the EVO IX with teh stock 16G-9. At 330-340whp it's quite difficult to run high 11's, you'll need an excellent 60' time. The Exedy organic or hte ACT Street disc will hold this power for a few launches and retain driveability but they will wear out pretty fast. I actually do recommend the Exedy Twin plate because it is just so much more driveable and will hold the power longer. But no doubt it's a pricey clutch. I would stay away from the Exedy singles .

You can run a more aggressive non-Mivec exhaust cam. Helix will be releasing their EVO VIII and IX cams together in about 2 weeks. Pricing will be GOOD! Stay tuned

The stock EVO turbo is an excellent street turbo. You can see what we were able to do with the stock 16G10.5 with the smaller compressor. Definitely a torque monste.r The 16G with the larger compressor housing will spool a bit later but make more top end power.

The Exedy Twin is very good - use that.

Reno, Most-Wanted had a mix of 110/93oct.

GGEVO9, do 22psi on pump gas, but it depends on where you live and how you're tuned. YOu haven't filled out your location profile, so we have no idea what pump gas is for you. Is it 91, 93, or 94? Each one can run a different boost safely.

Gruppe-s, I don't know what 330-340whp equates to on your dyno, but Most-Wanted already went 11.5 without using C16, without any cam upgrade, without an FMIC upgrade, and without being custom tuned for race gas. I think an Evo 9 with all the bolt-ons and custom tuned on C16 would make plenty of power for mid-11s. It would still require good driving, but it wouldn't take Most-Wanted's crazy driving, since it would be even MORE power than he has.

 

340 on their dyno is like 390 on a dynojet. Most Wanted is likely putting down approx 370 on a dynojet with his race gas mix (probably 102-105 octane?). You dont need c-16 to run MID 11's on the IX though, that has already been proven. You just need the driving skills, track conditions, and a really nice clutch.

 

He would have to be driving very good for some 11sec times on simple bolt ons. However, the twin disc is not very streetable. However, if its just a track car then ok.

 

How is a twin not very streetable? Please explane!

 

Well drive one and then come back and tell me how it went.
