Few things...

1.) MIVEC head flows better, yes.
2.) Evo IX's take LESS timing by FAR compared to Evo VIII.
3.) Evo IX's on pump gas do GREAT around 11.8afr.
4.) Has the car more in it? SURE THING if it were aggressive. The fuel the car came in with, and the datalogs recorded showed the car loved what it was seeing. Timing was relatively conservative, so no this is NOT a ***** to walls setup.
5.) FYI, Similar setups run around ~350awhp on a properly calibrated Mustang dyno on straight pump gas, good timing and boost.
6.) Again, this is not a ***** to walls setup .

 

For a conservative pump gas tune that's not bad. Run some E85 and about 30psi!

 

that graph making baby jesus cry.

 

We could have smoothed it out to be as smooth as baby Jesus's *** but then we would loose a few ponies

 

Numbers look good get some e85 in that!!!

 

If the car made 366whp/310 lbft @ 23.5 psi, but only went to 370 whp/311 lb.ft @26 psi, I'd leave it at 23.5 psi.

 

Good to see some results from this setup. It's something i have been throwing around as a future setup for myself.

 

On this setup with all supporting mods. You should pick up 5-7hp per pound of boost. The turbo by no means is maxed out on this setup. On 93 11.5AFR the car should be safe and making power up to 28lbs. This imo, seems like a very mild tune.

OP:

Also, why did you only rev to 7k? I know your peak power on the green with your setup should be between around 6.8 (which it is), but you should rev it out. You have the cams and more than likely you will rev to 7.5-7.8 when racing. It's always good to see how you hold boost out the top (from peak to 7.8k). There are lots of tricks you can do to help hold better boost out the top. What kind of Wastegate do you have?

For example. On my stock turbo I'm holding more boost, making more power, and making more torque than most Greens that have a higher peak power than me. It this case my car will pull better from 6.5-8k rpms. Two nights ago, fastfreddie and I went out to datalog my car (running only wastgate/no boost controler right now) and at night I was spiking 34lbs and holding 28.5lbs at 7.6k rpms in 3rd gear.

 

Who said turbo was maxed? Who says on 93octane itll make boost "up to" 28psi? Boost is NOT the only part of the equation, AFR/Timing/MIVEC/Fuel all goes into play.

FYI, this turbo will make power even at 34psi.

Again to reiterate...

1.) MIVEC head flows better, yes.
2.) Evo IX's take LESS timing by FAR compared to Evo VIII.
3.) Evo IX's on pump gas do GREAT around 11.8afr.
4.) Has the car more in it? SURE THING if it were aggressive. The fuel the car came in with, and the datalogs recorded showed the car loved what it was seeing. Timing was relatively conservative, so no this is NOT a ***** to walls setup.
5.) FYI, Similar setups run around ~350awhp on a properly calibrated Mustang dyno on straight pump gas, good timing and boost.
6.) Again, this is not a ***** to walls setup.

 

I understand this. Most tuners should know this! There are some tunners that prefer to throw timing at a car instead of boost. I know how the "equation" works! What I'm saying is that with the right "equation" this turbo will make power upto 28lbs on conservative timing map and an agrresive MIVEC map. There are still a lot of tunners out there that have not mastered the MIVEC tunner and inturn are hurting power. Could be a reason why his friend made more power on a much more mild cam setup???

I also don't agree with you that this turbo will make power on 93 upto 34lbs. Maybe 93 + Meth, sure!

 

Exactly, with HKS 272's and less boost I made more on a pretty conservative tune with 11.0 a/f ratios and not crazy timing numbers. When Kuniiiizzzeee is saying that 8's can take more timing, sure, but 9's have MIVEC which should make up for that by far for stock frame turbos, especially since they can flow more air. I think the tune can be retuned for better power especially with the Kelford 272's and can be richened up a little so it's not 12.0 a/f ratios IMHO.

 

Sekula, again if you didn't read, take a look at what I said. Read #4 and #6. I KNOW there's more in it. I never said there isn't, I even told your bestfriend Eugene the same thing .

 

I'm curious to the timing. If someone could share what would be considered agressive, and what is conservative, at peak load and at peak RPM(what ever it may be). How does it compare to this tune?

 

3@3500->11degrees at the top end. AFR did not exceed 11.8 afr. Since then the boost WAS increased so things may have changed, (look at first post boost was not at where the car was tuned at -23.5psi and now at 26psi).

 

Looks good for street driving. That's about what I run at 26 psi. No knock even in a 98 degree dyno bay, with Florida humidity, and back to back to back pulls to verify.
