Well compared to the Dyno pack my ride was on before the Dyno Dynamics it seems like it could be a 20-30 whp difference in reading.

But anyway that also could mean on other types of dyno's on other days yadda yadda yadda the numbers can also be higher...

Oh and the Greddy rear, that one kit says you can "cover" up the other side so it is one exhaust looking... I am wondering what that is exactly, though anyway since I do have a single exhaust it is a kit I was thinking of... Either that or the Carbon Creations N-1 style


Yeah 402 somewhat around 9.5 psi. Spikes alittle during daily driving that I can tell from data logging... So maybe I could be making more or that is a result from going slightly over 9 psi (the 400 whp).

Oh well, pretty much doesn't matter compared to just running well overall

 

LOL...dude your car is sick...I can't get over the gains you got from the tuning. If I didn't have some BIG work going into the car in the next month I would just get the EU and work out a way to get it tuned. But it looks like right now there are some MUCH bigger things in the works for my motor and car

 

Thanks folk, without your help (along with other folks) car would have been gotten rid off a long time ago (def. at my loss). But instead things are good instead.

BIG THINGS huh? Will be looking forward to that Also any thoughts on the TurboXS UTEC? I think honestly that would be better overall.

 

Extracting the power isnt an issue..its there..trust me. We had a couple of issues to deal with. First, a faulty wastegate was causing some boost fluctuation at higher RPM. But most important, the CUSTOMER decides how much power they want...not me. Everyone understands that a 450whp motor will not last as long as a 400whp motor...even with a perfect tune. Kelly requested 400whp, and this is about what we delivered. And now, the car runs cleaning and smoothly all the way to redline, and pulls like a tank.

One last thing...9.5psi on a single T kit is signficantly less airflow that 9.5psi on a TT kit. This is why it takes more pressure to get the same power out of a single T kit. Airflow is the key factor...not pressure...in determining power output. We regularly get 400-425whp on the TT kits at between 6.5 and 8.5psi.

Hope that clarifies it.

 

After some thinking I have decided to go with the TurboXS utec, I am very curious to see what will happen!

 

Yeah I would have gotten it, if it was available... But instead the EU came up and I needed a solution to help my problem... And it did, so I am happy with the EU... But still would go with the UTEC if it was a available

 

Yes it does clarify things. I in no way meant any disrespect to you, CPR or Kelly and his car. I made a mistake in "assuming" he wanted the most power possible given the mods he was doing. I didnt know the details of the problems, or the fact that "all" Kelly wanted was 400whp. I am fully aware of the fact that 9 psi is much different on a ST kit compared to a TT kit. Thanks for clearing things up.

Sharif-if I or anybody came to you with the same mods as Kelly with a TN kit, EU, return fuel system, upgraded injectors, free flwoing exhaust, plenum. Do you think 420-430 rwhp would be possible at 9-9.5 psi? I know you were at SEMA, did you happen to see the Modified Mag Z with the TN kit? It had a dyno under the hood 45Xrwhp 500ft/lbs SAW corrected. I have no idea how much bost they were running or what they did but you wouldnt happen to have any info on that set-up would you? I was too hungover and tired to even ask about the car when I saw it

 

Intresting..... please someone inform us more about this Z!!!!!

 

That car is running boost in the 12-14psi range....MIA can probably tell you that amount of boost. Actually..maybe I was talking to Dave at AAM about that car...I cant remember.

I dont think 420-430whp at 9.5psi is going to happen very often on pump gas. It's just not quite enough airflow to do it safely. On Peking's can, we also ran between 85.-9.5psi and got a little over 400whp on his. If you run more timing, it will knock on 93 octane..on the road. Not on the dyno...but it will on the road in the higher gears. We always road test afterwards to confirm timing once more, and insure there is no audible detonation. I am not saying that I am the best tuner on the planet, so I am sure someone can get 430whp at 9.5psi...I just dont feel comfortable doing it to a customer car on pump gas..thats all.

We easily run 10-12psi on these cars and make that power safely. I've had the "how much power" conversation with several customers prior to tuning. But like everything in life, there is no free lunch. And many customers that daily drive their cars, would gladly trade 20whp for a larger margin for error, and greater engine longevity. Peking and Kelly's car cant hold traction in 1st or 2nd gear at all, and start spinning in 3rd on some roads Oftentimes, dyno charts are mostly for bragging rights aways...and I guess there is nothing wrong with that.

 

Just curious, did you replace the wastegate or did the boost controller take care of it?

 

CP changed the wastegate spring to the smallest 6lb spring, and we still had too much boost. The boost controller helped a lot, but we feel that wastegate is defective. AAM also ran a bunch of diagnostics on it as well, and we both came to the same conclusion.

 

Yep, my wastegate is toast and getting worse. Peaked 11.1 on readout on the boost controller the other night with it set at 8.5 PSI. I'm once again driving the car like a wuss until I can get this replaced. I have the peak warn set on both my Defi link-controller and the Blitz just to keep me safe. .

Car sure does pull hard though

 

is Turbonetics going to replace it? I am a little worried that mine is not working correctly either. I hit 10psi but have not had anyone try to tune it down yet.

 

You cannot "tune" the boost below the Wastegate spring pressure, so if you're getting too much boost and it's not due to a boost controller malfunction, your only option is to go to a lower tension WG spring and either leave it at that, or install a boost controller to raise the pressure above what the WG spring provides.

Oh, and yes, I spoke with Reggie a Turbonetics. They are going to send me a new gate in a week or two.

 

I have not installed a Boost controller yet. The shop said I would need a lower spring to use it anyhow. So I guess we will try that when they do the install.

 

When I was still using the ECU reflash, we tried using a 7 PSI spring vs. the 9 PSI spring that comes with the kit because I was generating almost 11 pounds of boost. The 7 PSI spring is the "next step down" from what I understand. It did nasty things to my power, dropping it into the 330's, so if your kit operates anything like mine did, a boost controller is likely in your future.

 

The kit is installed on a built motor and tuned via a piggyback. I wont divulge too much as I'm not sure if I can. I will tell you that it is the same turbo and kit everyone to date has installed. It is running 14 PSI I believe. The numbers were actually 470 RWHP and 500 ft/lb of tq with AFR dipping into the 10.5:1 range. it was made OVERLY safe as it was being tuned last minute for SEMA. Re-tuning will occur in the future but thats what it has for now.

 

Nice...I have no doubt this turbocharger can generate 500+whp worth of airflow.

 

yes sir

 

Kelly and Sharif, that's awesome dudes.
