Wow, an excellent thread this is with great info and very good questions. Warr, congrads on the upgrades and happy to see your boost situation getting better.

 

Oops I got that backwards for whatever reason. I myself have a range colder and thought that you went back to stock heat range.

 

hmm Warr:

Just want to make some observations/questions that I know you may be able to answer.

Boost levels @347 whp were 28 psi?
I know it made 380 + tq but of course when the boost spikes it will boost the tq curve like hell, but did you saw if any an advantage of using the Forge WG actuator? I know you cant discuss the amount of timing on your ECU but all this is just making a quick comparison with my car recently and the dyno numbers

@22 psi my car made 340 whp on dynojet on pump gas no alky
@25 psi my car made 370 whp on dynojet on C16 race gas

AFR were at 11.2-11.4
This is just a comparison on different parts, not bashing anyone, Warr when you can send me a PM so we can discuss on this.

 

That's a very good question. In the past, I always shifted right after 7000rpm, but that was because I hit peak WHP at 6800rpm or so, and by 7100, it hadn't fallen off that much. Doing so allowed me to hit the next gear around 5600, which was always right in the sweet spot. NOW, however, my WHP peaks at 5750 or so, then declines slightly. The good thing is that even though it starts to decline, there is really no "fall off" whatsoever. I stop climbing due to just the nature of the stock cams or due to boost leaking up top, thus causing the turbo to blow hot air, and thus causing some timing issue (notice the wavy ripples at the end). I hope to remedy this by shortening the WGA arm, then re-installing with the turnbuckle tighter. The goal is to keep the BOV from opening so easily - it may be leaking out this high boost at rpm. If that is fixed, then you will probably see the same basic curve except that it won't start to fall at 5750. It should continue to climb all the way to 6500 or so before starting to fall off. If that happens, my whp will be noticably higher, and I would be able to rock out at the drag strip, since I'd have peak power in the middle/end of my gears when racing.

So, for now, I would probably shift right at 7k or maybe 6800, because that would put me back around 5300-5400 rpm, which as you can see, is where my nice WHP curve flattens out at its peak. That would basically give me no less than 330whp for the entire pull in each gear, except 4th, where I have to go to 7800 after power probably falls off drastically...

 

Don't think we need to take it offline. This looks like a good question or questions...

Yes, I was at 28psi for the 347/380, but 26psi for the 341/361. My PEAK whp was suffering on each alky run due to something causing the power to fade up top way earlier than it should. If you have your run file from the dyno, send them to me, so I can overlay. My guess would be that my 26psi run would have a very similar curve to your 25psi run up until 5750rpm where I run into some unknown issue, and you probably continue climbing. My peak WHP should actually be higher, because we never hit peak WHP below 6k rpm, but that's just another issue to resolve. The power curves leading up to that point are amazing.

Also, did you run your 114mph on pump gas (340whp) or race gas (370whp)? It could come down to different dynos, but I expect to trap higher than 114mph on my 26psi setup. If not, then it will mostly be limited by my 4th gear running out of breath without cams, since I have to pull all the way to 7800 (6spd).

 

Do you suspect the mysterious loss on the edge was you reaching the limits of your stock ignition? Or did the numbers appear to be keeping up?

 

It's very possible that it's due to the ignition, which is why Al suggested an HKS DLII. However, I'm not really making THAT much power, and there are others out there making much more power on the stock ignition with big boost on alky, so...

I will try the WG fix first, then if that causes my BOV to behave normally again, I will hit the dyno again. The cost starts to add up, but the results are worth seeing...

 

I ran the 114 on the 340 whp map, I havent been able to test the C16 map since last time was a dual event we made here in PR, first was auto cross (which I participated) and the drag event. I ran my car like if it was stolen on the auto cross so by the time I ran my 3rd pass on pump gas (I still had 1/4 of tank and was trying to get it lower to mix the C16) the clutch slipped, after that since I was organizing the event I parked my car and since December 3 I havent been able to hit the track to drag it again, I did run auto cross again on December 17, I expect to go to the track next week, I will go to the dyno tomorrow and find the last graph and send it to you. PM me your email, I'll get a print of the whp/tq graph. I think if my clutch holds together I can trap like 117 or close on the 370 map.

Good one, keep it coming.

 

Just send the electronic runfile, not the graph. I need the actual WinPep file if you have it. To send the email, click on my profile, then click "send email to Warrtalon."

 

ok!

 

Whew.. just read all your new threads finally.. good stuff.

You may want to check out he BR7ES or BP8ES for kicks. My car seems to like these a little better.

Sounds like you may be able to finally break into the 11's now

 

I'm using BR8ES. Did you mean to say that, or did you really mean to say BP8ES? I hadn't even heard of anyone using those yet (usually BPR8ES or BR8ES).

 

Yes I meant BR8ES.
