a lot of reasons. I laugh at you saying "you can only get 450whp with your kit and built motor." A legitimate 500 whp on a Z is about the limit for the street IMO.

 

Laugh all you want, but I wasn't putting you down. Sorry you took it that way.

Anyway you say EMS, but GRD is using the same EMS.
Low compression? I doubt your lower compression is costing you 70whp.
Goals? If your goal is only 450whp then why are you waiting for the APS EMS? For that matter why did you even build your motor? Seems like many of your APS brothers are pushing that power level and more on stock blocks with no problems.

 

When you drop compression it can easily cost you 70 hp. I am running 8.8:1 vs the stock 10.3:1 compression. I was also tuned to 92 octane vs 93 octane that GRD's car is on. Tuan had me to 460 whp on 93, so there is 10 HP right there. My goals were around 500 whp when I put my setup together. During the tune I could not hold my max boost to redline, due to not having enough fuel - not the actuators. Talking to Tuan, he thinks there is more fuel there, but is unsure how much as he has put in as much fuel as he can with the unichip. Once I move to a new EMS we will see.

Just because others are pushing higher numberst than me, doesn't mean I want to. My intentions from the start were not big numbers, though I am kind of knocking on the door. With the way my car is setup now, max boost at 14 lbs tapering to 11 at redline. I am looking to move to a new EMS mainly because I want to hold boost to redline - 14 lbs all the way. Whatever HP number that equates to is fine by me. I built my motor for a number of reasons. I wanted a somewhat reliable setup, if there is such a thing. If I wanted big numbers, I would have done headword, cams and a few other things.

Also, just an FYI, my car is pushing equavalent TQ numbers to GRD's shop car at 500+ whp. Also, if you check the boards, my car pushes as much tq as most APS setups in 500+ territory, some 550 territory.

 

The SFR shop car is sitting at 476WHP at 10 psi on 91 octane though.Bone stock motor,heads,cams,sparkplugs,clutch,etc...........No plenum spacers or anything else except for a turbo system and exhaust.This has also been dyno three different times over a period of one year, on two different dynos(Dyno Dynamics and Dynojet).

Tim, that is some good chit man... That is pretty damn impressive on a mostly stock car...

 

sounds pretty awesome. I was thinking there were 1 or 2 other people that had stock blocks and pushing over 500 and actually driving it at that level regularly. I think Bri was one and eventually he had head lift and now has a MONSTER of a built engine.

Ryan, (Metal Heart)
I think the question you asked needs to be defined a bit further to specify how much/many miles an engine has on its highest HP/Boost setting. In my case, yea I have 490whp @10 PSI, but I do not run that on a daily basis. Only at the track and when I want to play around on the street. SO, reality is I have like maybe 100 miles on the engine at that level, but most of those 100 miles are hard WOT runs. I have maybe 5,000 miles running about 425whp @ 7.5 PSI, with a good amount of heavy WOT thrown in there for street encounters. And say around 2 - 3,000 miles on the stock Greddy boost 375whp @ 5.6 PSI for highway cruising/trips.

I guess that is the advantage of having the boost controller and multiple maps tuned. I think there are probably a # of people who can say they are running 500+ on a stock block, but I very few actually drive that on a regular basis.

Brent,
I'll PM you. You may not know it. But you've met me already haha. I'll explain in the PM.
That being said. IIRC Brian (Big Bri) mis-shifted from 3rd to 2nd instead of 4th and over-revved the motor. It caused an oil leak and spun a rod bearing. I could be wrong, but thats what I recall. Might've been headlift, however with OverZealous' new mod for the head, this might be avoided in the future. My point being, bigbri was running 500whp on 91 with aquamist daily. But, he had cams/headwork. So he's out.

As far as the definition, I'd like to see at least 2000 miles of at max whp driving. In your case, 2000 miles of 502whp. Sounds like you need some more miles

 

Alright, just to keep you appeased I will set her to max boost for the drive down and back for the ZdayZ event. That should be at about another 1,500 miles in 4 days.... Is that dedication for you or what...?

 

Hahaha, I effing love you man
Definitely!
I assume you got my PM?

 

never tuned on 93 with this setup. I run the 100 octane map daily.

 

100 octane every day?
is this car your daily driver? or just a few times a week thing?

 

I bet you have a life sized naked autographed photo of TUAN....

That car isnt even close to being DD, quit BSin everyone here....that car is st8 up..."i was thinking about getting a turbo Mr. Tuan"..."okay, check out what you get".....go for a few passes down the block..come back TUAN HAS JUST BRAINWASHED YOU~!lol, If Tuan is the ultimate tuner how come chris' car blew up down the block after he tuned it , yeah im really gonna go there

And for the little ghey Jotech remark you made...were all one big family...im just the hot head...now go make me a chicken pot pie......

 

Yes.

Daily driver.

 

That is pretty nutz man... So, I gotta ask, you put 100 octane in for daily driving... Where do you get it, or are you adding some type of octane booster to normal 93 gas? Must be a Sunoco near you huh...

Have you seen any negative effects (other then the lighter wallet) from running a higher octane in daily traffic? Just curious.

the best is unleaded 109...MmmMMm...MmmM....good, put 3 gallons of that and pump.....call it a day

 

no side effects. Drives the same. Just a lot more power with the 100 octane map. I live near a 76 station with 100 octane at the pump. $4.89/gallon.

 

My car (G35) had 525whp@15psi on stock engine and did 11.0@125mph.

 

For how long?

 

Chris' car blew up because Chris completely F'd up his install. Bent his fuel line, left nuts in his IC piping, coolant leak, etc.

Say what you want, you obviously know more than me. Why don't you call GRD and ask them about their car and how many miles, dyno pulls, etc it has on it if you think I am BS'n everybody? Their car is definitely more daily driven than mine is.

 

LOL, thats a shop car, and from what i heard the motor is pulled right now. Lets look at some GRD's fine threads

hey if you cant tune it, sell them all new stuff

WoW, they couldnt even get your car right the first time

Ide find more....but i got zero2prove...lol

Tell Tuan whats up with the APS injector Kenny loaned Jason for the kit he sold him??? WoW never heard from the guy after that...its funny GRD dont pick up when people are mad....

So chris car ran fine for 3 weeks...then ...he went to GRD...right....3 blocks later "boom". Tuan being Mr. tuner shouldnt have touched that car or DYNO'd a car that he though was ****ed up.....Dont they check the cars before the put them on the dyno anymore??? So if it blows the customer cant blame them
