Please Noize, Shiv, David, take it easy one me. I have been a DIEHARD and LOYAL Vishnu customer for 2 years. I have the Stage 1+ without the XEDE Flash. I only really post in the VISHNU forums because I respect the Vishnu crew and believe in Shiv. I have to say though that I am VERY dissapointed in the performance of my Stage 1+ and here is why. Im not going to talk dyno this dyno that.

I have a friend that has and EVO with the following mods: Turbo Trix mail in flash, HKS RS intake, Hallman MBC HKS 264's and lower intrecooler piping. I went over there so he could fix my clutch problem(the pedal just needed to be adjusted) and he said why don't we go for a quick run. Anyway to make a long story short we started in 3rd at 3k rpm. Well, he whooped my **** by 4-5 car lengths and that was by the end of 4th. He spooled quicker then me so he got and immediate half car from the punch. The he pull to about a car and a half at the end of 3rd and in 4th he go another 2-3 car lead. Now I don't have a custom map and neither does he. I made sure I was running the Stage 1+ 93 map. He just dropped in his cams a couple of days ago so he is not optimzied either but a 4 car legth is quite SAD. Does something sound wrong? Now before you dis me on my driving skills, it was from a punch and its not to hard shifting at 7k. Why may he car be so much quicker then mine and what can I do with my current mods to get a little quicker? I just dont understand why he spools so much quicker. I though that an open element intake does nothing?



I know this is going to hurt so go ahead. Im just kinda depressed.

my guess would be the cams... cams open up ALOT of power for the evo... nothing's wrong with your car IMO

 

See but I have cams too, HKS 272's

 

With the cams, it could be low end torque vs. peak hp that the 264's vs. 272's generate.

He could be running slightly better quality gas (93 octane != 93 octane everywhere). His car may be running a lot of advance because it's happier on that gas etc etc.

 

Tony has cams also...The MBC may be the difference since it actually allows the turbo to spool up quicker vs the xede controling boost in a smoother and linear way. The stg1+ base maps have waste gate duty cycle starting at ~93% and without the xedeflash you won't see any boost above 20-21 psi on pump. before xedeflash even on 100 program w/dutycycle across the board at 100% I rarely saw anything above 21-22psi. Xedeflash made a world of difference on mine even with the stock cat back.

Now I run a 3 in dumpback and see up to 27psi on 100oct (I'm a race gas junkie), fixing to go catless...

 

Well actually I am seeing 1.6 bar peak on my car. So thats around 24 psi. It spikes then tapers to aruund 18-19 psi. I do have the DYNOFLASH Stage REV. Just the flash that get rid of the top speed limiter and the Fuel cutoff. So JORGE what do you think the deal is?

 

Are you runing a base MAP?
Who did your cams?
What are the cam gears set at?
Witch exhaust do you have?
Do you have a Cat?
Are there any other issues with your car?

We can make you faster

 

he isnt tuned for the cams?

He may be running pretty lean

Get that ***** tuned and youll be kicking his ***. The torque diff between the 264 and 272's would not make that much of a difference.

go get it tuned, TUNING IS EVERYTHING!!

So i take it you're on the stock fuel curve?

How are you running cams with only having your fuel-cut and rev lim removed?

 

His boost at the top and his cams at the mid range may be the difference. BTW hope you weren't street racing full out in 4th you bad boys. Xedeflash should help you raise the boost as that along with bump[ing up the rev limit is it's purpose. What settings are you running on your cam sprockets, bottom end for faster spool up or top end for max peak power?

 

See the thing is that you need to know if somthing could be wrong with this guys car before you assume it's the tuning. I have seen alot of cam gears installed wrong and that does make a diffrence.

 

Slightly better gas (like what...a point or two oct. or are you talking one brand against another?) won't make 4 car lengths difference.

Even if the 264s made more torque at that point in the curve, the "better" top end of the 272s should have at least slowed or stopped the pull by his friend, and way up top he should have gained a little, if all that was different was cams.

If he was running that much more advance than in your engine, and made that much of a difference up top, you've got a sick engine...(you been flogging that bad boy?, check your compression and leak down lately?)

 

I'm just guessing here, but his mail in flash w/mbc may be more agressive(a/f, and timing) than the xede base stg1+ map you have.

 

That's not my experience. Even in my previous WRX, you would be surprised the differences that result in timing advance being dialed back from a tank of 93 octane at one gas station vs. another. And I am talking 2-3 car lengths difference. I doubt the EVO is much different, if slightly less aggressive with changing its timing advance multiplier.

That's totally possible, he might be running dangerously lean and not know it. If in doubt, get it professionally tuned and take it to a track and see what happens then.

Lastly...he might just have a stronger car than you, there's plenty of evidence for some cars being freakishly strong.

 

tony is right...cody's car is fast...i have custom tuned stage 1+ w/pwr fmic...and his car pulled on me prior to having cams.

 

Hey guys the car he is referring to is mine. I do not exceed 20.5 psi (tapers to 19) and run the same gas as Tony. So it is not the gas and it is not the boost. He runs more boost than me!

The things you are all mentioning could be valid, but we are talking about multiple car lengths. I easily pulled 2 car lengths each gear which is up to maybe 5 total. I was not slowly creeping away. I was kicking his *** pretty hard. I would also like to know what's up with his Vishnu setup. Thanks.

edit: And yes, asasin79 also knows the wrath of my Evo even before I was cammed. LOL!!
