Well, once again I made a poor showing at Fontana and was embarrased by Sam a few times... I changed the setup and if my car holds up until the next street legal I'll be there.

I installed the FP2 Cams but couldnt get knock to disappear unless I ran 10.3 ~ 10.5:1 AFR's and 6* peak timing, all I can say is 91 oct sucks. I talked to Sam about running Meth vs E85 and I started doing some research, down in SD there is an E85 station on my way to work! GTFO!
The next day I ordered a set of FIC 950's and called FP to get their new HTA68 shipped to my door.
I decided it would probably be a good idea to tune the E85 with the E3 16g that was already on my car so I could see my gains from the HTA68.
After juicing up with E85 I was able to lean my mixture to 11.3 ~ 11.5:1 and advance timing to 15* peak and no knock, boost at 21psi and seeing 37lbs min on the 16g. I installed the HTA68 and saw 41lbs min with nothing really changed on the tune... I feel like the tune can be leaned out even more and peak timing advanced a few more degrees safely before I start seeing actual KNOCK in my logs, maybe I'll turn up the boost to 23psi and tune from there?



I do have a quick question though, hopefully someone has the answer. My WB reading and WB logs in link were matched up perfectly before I did the E85 swap. I noticed when I was doing my 3rd gear pull with the HTA68 that the WB was reading 11.3:1 and it was logging 12:1 in link. I have RawWB logged but I'm trying to figure out what a 11.6 ~ 11.8:1 AFR would look like in the RawWB voltage...

Thanks a bunch.

Did you notice a difference switching to E85. Smell is a lot different also huh

I'm sure he did. on my car we got 306 AWHP on 91 and then when we changed to e85 the first pull with no settings changed other than changing the injector global settings for the different fuel we made 325 AWHP and after tuning it in leaner and with more timing we got great gains out of the e85.

I can't wait to see your sexy ride at the drag strip again and hopefully on the dyno for some good tuning and numbers soon.

I am wondering what my PTE 50 trim will do as well. Unfortunately, you are having the oil pressure issues with yours. I still have my balance shafts and haven't had a problem. Wastegate starts tripping out anything above 26lbs of boost. Running e85 as well. Cory definitely has one of the cleanest DSM out there. Are you running your HTA externally gated??

You need to go higher in boost and add more timing. Basicly keep AFR flat, no matter what the AFR is, go for a flat fuel curve. From there you can raise or lower the AFR value all at once. I keep conservative on e85, its got a really small threshold. From there, when you have a flat, rich ish (like 11.4:1 guage value) I'd raise the boost. Shoot for as much as you are comfortable with, maybe 28ish. From there, go and add timing all over the WOT areas, untill you see like 1.4~2* of timing pull, then go back maybe 2~3*.

Bring it, I'll probabaly still be running that 16G next time, I still have a few tricks up my sleeves.

Sam your crazy, 25psi on the stock head bolts/gasket is PLENTY of boost... I'm nervous watching the boost gauge climb to 21psi so 25psi will be MORE than enough, if my car hit 28psi I'd probably shit myself. If worst comes to worst though and I'm up in Fontana grudging you again and its close I might just do a 28psi run so I can really show that Talon whats up... Its not my car that needs to make the showing, its the driver and everytime I race up there I can't for the life of me run a decent 60ft time.

I'll start twisting the MBC and get it to 25psi then advance the timing with a 11.5:1 AFR. The guys on tuners are saying 12.5:1 on E85 isn't uncommon but I cant imagine that being a safe AFR for a DD running 25psi with 20*+ of timing.

just start around 11.5. really, beyond 19* of timing the car doesn't pick up much more power, no point in pushing it.

For those of you interested in the gains that can be had from going from a 91 oct 16g setup to an E85 setup OR want to see the improvements of bolting on an HTA68 here are a few "go fast" results from datalogs I have...

91 octane with a E3 16g and FP2 cams...
AFR's - 10.5:1 Timing - 7* Max Airflow - 35.1 lbs/min. @ 7k Boost - 21psi HP est - 270 hp TQ est - 280 ft/lbs

E85 with a E3 16g and FP2 cams...
AFR's - 11.5:1 Timing - 13* Max Airflow - 35.2 lbs/min. @ 7k Boost - 21psi HP est - 324hp TQ est - 311 ft/lbs.

E85, HTA68, and FP2 cams...
AFR's - 11.8:1 Timing - 13* Max Airflow - 41 lbs min @ 7k Boost - 21psi HP est - 372 hp TQ est - 321 ft lbs

What about 91 oct. hta68?

I've done 330whp on a hta68 on 91 octane only @20psi. Impressive turbo.

With boost still hanging out at 21psi on the gauge and street tuning it my Horsepower est. in link is showing 430... wonder what 25psi will do? It feels like the cars trying to take flight, now its hard trying to watch the road/AFR's/boost/CEL while going WOT.

:yawn:

Man....it's tempting as shit to switch to E85 now. I just need some ARP's and probably bigger injectors. And cams . I have that money right now, I just don't want to spend it and probably break something lol

I don't know what it is about those FP cams. Normally people run the FP1's and FP2's with no problem. But as soon as they jump up to the "x" versions it goes knock crazy.

Good numbers none the less.

I would totally go E85. I am running E85 right now and man can I tell you it makes a world of a difference. I am running the PTE SCE5031 right now on 24lbs of boost with about 18-19* of timing. Ran a guy in a 350z twin turbo gt28 last night who told me that he ran me on a tune where he was at 422 hp. From 40-130 i had him by 1/2 a car to 1 car lead on him. Lot of this I can thank E85 for. Chris ran him on 91 with a better set up than I have (stock 7 bolt) and didn't win. Same lbs of boost. If its not your daily driver (cause mpg suck ass with E85) then go E85, if not I think Meth injection is the better way to go. You don't want to have to alway carry your laptop to switch your tune from e85 back to 91. Flowing about 47lbs/min right now. Just my .02

I normally always have my laptop with me but it doesn't matter. The E85 station in Brentwood is just up the 405 from me. And I'm awake at insane hours so filling up when there is no traffic isn't a big deal either lol. We'll see. I just wish there were MORE stations open
