hello everyone,

I will start by saying I searched, but I wanted to get some other peoples thoughts on this.

So I went to the track last night, and here is what I got. I know my 60' needs some work, but the car does not seem to be making any power. When the car was stock, I would go 13.8x with a 2.00 60'. Mods are:

3" tbe with high flow cat
injen intake with upper intercooler pipe
turbosmart bov

I have removed the bov and am going to take off the cat, but what could be causing the car to make less power then stock? Any help would be great. thanks!

60' 1.962
330 5.804
1/8 9.040
mph 77.21
1000 11.804
1/4 14.158
mph 96.79

 

flash lately? with an intake, that's usually recommended. . .is that bov vta or recirc? that would mess things up as well. . .

 

Well, you have mods without a tune, a cat, and it's the hot summer. You've basically done everything we DON'T recommend.

BOV and intake as first mods = terrible.
Injen Intake without tune = terrible.
UICP = bling only, no power
No boost control or tune = terrible.
TBE = good, but HFC = 10-15 less whp

What was your mph on the 13.8 runs when stock?

 

Warrtalon, I will pull up the old slip when I get home and let you know the mph.

The bov had the plate on it so it was vent to intake. I just took off the bov and I am removing the intake tonight to put all the stock airbox on the car. I will also get a test pipe and take the cat off. After I do this, do you think this will help me at all? I dont have a flash on the car yet, I planned on getting one shortly but wanted to get the mods on the car before I took it in to get tunned. Also should I do the boost controler and fuel pump next?

 

Please look around, there have been so many posts on this...or look at Warrtalon's sig for a good start..

 

I think we spoke last night, anyway, the first thing I would do is a boost leak test, its simple to do and free.

 

Hey alwaysinboost,

I am going to do the boost leak test this weekend as well. I am going to homedepot right after work. I hope somthing turns up with this.

 

let me know...

 

There really is nothing wrong with your mods, people are just being ****'s because everyone isn't the same. Your car could USE a flash, but it isn't the reason your car is running so slow. The post maf pipe from the intake is the only mod that could be hurting your performance.

Whatever you do dont buy more parts, find and fix the problem because there is something wrong. Until you get it running how it should DO NOT complicate the problem by adding more aftermarket parts. The biggest problem with your intake is actually the pipe after the MAF, so if you wanted you could remove the injen hardpipes (maf pipe+UIP) and still run the open element filter and try again

Like alwaysinboost said, a boost leak check should be your first priority because they are probably leaking.... so do that and post back

 

A boost leak should not be the first priority, because has not done anything to change the IC system. Yes, he could still have leaks, but he hasn't switched the boost lines or the IC pipes. The intake being untuned is the worst part. You are wrong to say only the MAF pipe can hurt, because the filter alone without a tune throws off the MAF readings.

He's already done a good job of returning to the stock intake and BOV (for now). He does not need to buy anything yet, but he should run how the car is now with just the TBE and HFC. Then, if he's still not even seeing 100mph, do a boost leak test. Or, he could do one beforehand, but like I said, he's much less likely than most to have leaks that weren't already on the car last time, since he hasn't changed anything that would leak other than the BOV, which is now back to stock.

People always talk about waiting on a flash until they have certain mods, but think about it. You didn't wait to go to the track, so why wait on the flash and make the car slow and untuned. If you have to, get a cheap mail-in flash or e-flash for what you have now, then when you have time to get the rest of the mods, get a discounted mail-in reflash or e-flash.

That BOV _should_ work fine when setup properly, and then the intake can work fine WITH the tune, so hang onto them. Or, you could sell both, use the stock intake, get a JDM MR DV, Forge UNOS MBC, and fuel pump with a flash and have a perfect setup.

 

didn't you read the first post, he has an UICP. Not having a tune with his intake isn't holding him back either. Its a boost leak that is keeping it from making power, and maybe the aftermarket BOV isn't adjusted correctly.

as far as the intake goes I think if you remove the section that connects the MAF to the compressor inlet you will be fine. The problem is that curved metal pipe will mess with the MAF sensors ablity to meter the air, causing problems. Just put the stock elbow back in there instead.

 

Thanks for the help guys, I am going to check for the boost leak today. I put the stock intercooler pipes, intake, and bov on last night and the car seems to be running a lot stronger. It is hitting 21 psi now instead of 19 (with the injen intake and bov). Is this a normal thing? All that is on the car now is a tbe with the hfc. This thursday, I will head to the track and test things out. I will let you know.

thanks again

 

Sorry Clay, but I couldn't disagree more. First of all a boost leak test should be the number one priority because he has installed an injen UICP, combine that with his unfarmiliarity with modding evo's and one could imagine hes got a nice leak.

Also the number one reason to blame intakes for running poorly on a stock mitsu flash IS the MAF pipe. Ask any respectable EVO tuner. The filter hardly changes anything at all. I also know this personally because I have datalogged this on my palm with ECU+ and backed that up with info I found by logging and timing back to back to back runs of a 3rd gear sweep starting @ 3500 and ending at 7500 on the same day with the same weather on the same part of the same road. I've spent a fair share of time comparing the open filter to the stock box and there is 0 power difference. I also breifly talked about this with martin musial of AMS at the NASA autobahn event and he basically confirmed the part about the MAF pipe. If any extra air is gained from the open element cone filter than the MAF will read it and correct for it.

 

Well if he had an Injen Intake/UICP that means that he did have a new MAF pipe so it could have been hurting abit without a tune. It could have been a combo of things as he mentioned he is also now able to hold 21psi instead of 19 after putting the stock parts back on, which could indicate a leak also.

 

so I went again last night and here it is. The car has all stock parts except a tbe with a high flow cat. Does this look right?
