just check out my build thread... tons of pics. Some okay quality.

 

So last night we took it out on the street for a little datalogging to see how the tune was since the mivec sprocket and waterpipe incident. All checked out, but now realized that during my initial tune the mivec was most probably not working at all! Now, that the mivec gear was fixed it started to mess w/ my idle and midrange drastically. A/F was totally different. We ended up having to add alot of fuel during spool to compensate. Result? spool up now is 500rpm sooner! We were pretty excited about this... so we continued to dial in the mivec by moving the advance curve into the higher rpm region (since the basic JDM map is geared for a 16g curve). So advancing the cam from down low all the way to 6500rpm where my T4 is nearing peak boost and it broadened my curve greatly. I'll need to post a new boost log from the AEM. Then pulling back the cam right after up to my rev limit at 10krpm. The odd thing is normally you pull back to zero or near it by redline... but since i hit peak tq in the same area we had conflicting requirements for the cam phase. As of right now... we started to pull it back in the upper rpm region. But curiosity got the best of us... so we decided we'll put the car back on the dyno and see about keeping a little bit of advance in there as it seems to steady boost better and lean the car out (per aem logger). Having to add fuel is a good thing, as I can only assume that consuming fuel at the same AFR can only mean we're making more HP. But we'll see on the dyno for sure. (Currently we are tuning at a 12.1-12.3 AFR on C16 (about 42psi now vs 39psi we were originally at when i made 802whp)

Im having to play Mr. Dad all week... so Huy has the car and will probably be taking it to the dyno. One of us will post updated results. Not to mention another try at the track asap, lol.

 

That must be pretty exciting knowing there might be some power left on the table and your spooling the turbo almost a full 1000rpms sooner!!!

Good luck and get those updates...

 

updates:

we tuned out the mivec advance and got a slight improvement on spool w/ this 70mm turbo. We ended up using a different mustang dyno (late midnight tuning session). This one showed both uncorrected and corrected whp(per weather conditions). The best pull of the night was 820whp uncorrected / 760whp corrected. W/ the smoothing on it lowered to about 743whp. I am not really sure how it works, but the weather that night was 44 degrees. I was told the 820 is what hit the rollers but the dyno lowered the whp for weather correction, I am guessing to a more avg temp of 75-ish etc. Either way, i wasnt interested in peak numbers since we're using a totally different dyno. What we did want to do was dial in the tune. A/F in the 12.0 range on C16 and boost capped at 40psi (boost controller maxed out) i was hoping to push it to 44psi, but we can do that at the track.

btw... for the guys asking for street vids. There are a few, but obviously i cannot post on here. You can PM me for youtube links. (or simply search "inline racing evo" ) Mine is the black evo.

 

what kinda boost controller are you using? The AEM boost solenoid made for AEM EMS?

 

Earlier you mentioned that a (505HP) C6 ZO6 makes 360WHP on your dyno. This means that the dyno reads roughly 71% of the crank HP at the wheels.

With that said, your car must be making over 1,100HP to the crank if my simple math is correct. Granted, there are very different drivetrains but an AWD drivetrain will lose more power than a simple RWD setup so then I assume there's even MORE power unaccounted for. Is my line of reasoning wrong? We have more than enough geniuses on here so I'm sure someone will point it out if so.

Anyway, put it on a dynojet or do a street pull and log and plot to VDR!

 

^^^^you must be dyslexic.

 

no, your line of reasoning is not wrong, you're simply just can't read.

 

wat.

I'm missing your point. I said a 505HP ZO6 dyno'd 360WHP on his MD. Is that incorrect? Where's my dyslexia? Nothing is backwards as far as I can see.

 

there's no real way to measure my HP at the crank unless i yank the motor and put it on an engine dyno which isnt going to happen. Thats why i dont bother to theorize what its really making at the flywheel/crank. I dont think anyone does anymore really?

I basicallt used two different mustang dynos w/ different scenarios as far as setup when i got my readings. 802whp on the 1st mustang dyno w/ issues on mivec gear (which were unknown at the time). Then 813 & 820whp (uncorrected) at another mustang dyno w/ the mivec working. The temps were cold in the 40 degree range so w/ the weather station correction on, it lowered to about 740-760whp on several pulls. Im giving both figures since some like the uncorrected which shows what hit the rollers on that given day and some like corrected for weather.
Anyhoo.... That being said, its an 800awhp car on these mustang dynos. I have yet to be on a dynojet so I dont know how much higher it will be. And yes an engine dyno to read flywheel/crank would be even more higher.

So imagine what the guys that lay down 1000awhp really make! lol

 

so anyways, our next chance at running the evo at the track was at IFO (Import Face Off) in Houston, TX. It was a huge turn out (from what i hear / saw pics as i was sick w/ the flu and the shop took my evo to compete) but it rained out. Sucks because a lot of pros came out... even Tony Palo/ Chris Miller were going to have a shootout. There were probably 3x 9sec capable evos out there as well. Here are some pics when it rained out, lol.
Im having some serious bad luck in track attempts.

Anyways, i'll try again at the next test/tune session weather permitting.

 

That sucks man... Was looking forward to seeing how people do at IFO in Texas.

 

That's all my compliment was based on. The fact that a ZO6 with 505 SAE rated HP makes a low sounding number like 360 on your MD. It really is amazing that your engine, if measured at the flywheel, would be making possibly over 1,100HP.

Sucks it got rained out. Nice FD rims and slicks; I got the same setup and they're awesome!
