2018 GT Whipple and still waiting

[olaosunt]

The same thing happened to me with the heat exchanger. The correct one showed up Friday at the shop while I was there checking on the car. It is massive!

No issues with IAT’s with the non HD exchanger ...at least at current boost levels
IAT’s drop like a stone at WOT
Temps are in Celsius

I'm not sure what mods you have, but has anyone looked over your car, or listened to your motor with knock ears? You might just have phantom knock. Sounds like these gen 3's are pretty noisey. Could very well be the case.

Just a thought. I haven't even read through the whole thread etc etc etc, but phantom knock can produce very similar problems with pulling timing even though you're running what would normally be plenty of octane.

Below graphs are knock after and before boostane

And spark before/after adding boostane to 98 octane .

I guess that is possible but seems unlikely since it went to making max timing as soon as I added a can of boostane .
Only mods other than the whipple/OPG/CS are CF drive shaft ,BMR lock out kit and DSS axles.

Any one have suggestions on how to get the 60 down?
If I can get it down to the 1.6 range the car should go 10.3 as it sits .Tires are not spining . Just won’t leave hard enough varying rpm from 1800 to 2200.Tires are 28 inch tall and rear end is 3.55.

2 step ? The MSD is being advertised as 16-18 but per CJ pony it is not compatible with the 18’s .
Not sure if the N2MB WOT box will work .


2 relay transbrake is out of the question as I won’t even consider it for my “Hellion race car “ because of all the horror stories I have heard about cracking cases(the “built “auto swap I bought for my 12 had been subjected to one and I had to rebuild almost immediately ).

Judging by your logs, I think you're right. Doesn't look like phantom knock. Some engines are noisy enough anything is possible. Like Subaru guys sometimes end up just turning off the knock sensors completely (not good idea) because their valvetrain is just so noisy. I knew of an ej25 swapped car locally that was constantly dropping ignition timing because of that, and it was a stock engine. But in your case it looks pretty consistent. If it flashed back up to higher timing and then dropped back to lower timing, then it might be phantom.

Try other 93 sources in town. Maybe you can get some power back without running booster every time.

How to get the 60ft down? I would say converter. That's the best thing you can do. When you launch are you brake standing at 2200? Or are you flashing to 2200?

On a blower car a two step is not really worth much so I wouldn't bother with a wot box. If your stall is too tight you'll still push through the lights on a wot box.

Also a guy on youtube (michael mac, one of the few car people on youtube who isn't an actual sore c***, I can't stand 99% of them), runs the PBD Trans brake. Seems like you need HP tuners to set it up, but he's running 700whp+, on slicks and it seems to be doing just fine. Broke an axel. But trans is fine.

My vote is for a different stall, and then a smaller pulley. That should get you going at higher rpm, making more boost too.

Thanks for the advice . The knock on the logs was with Sunoco GT 250 that is supposed to be 98 octane . I did see the same amount of knock on 93 logs on the street (I usually on fill with shell VP)
93 is probably fine for daily driving but I will at least add a can of boostane for racing with the 3.75 pulley .
I think it will need more octane on the 3.625 and will either run Ms109 to race or add boostane to 98.
I don’t think there are any aftermarket converters out yet for the 10r80 .
I have used Lund to tune all of my other cars before this one but if/when I ditch the whipple tune I think I will give PBD a try especially if I am able to get a transbrake tune from them .

 

[GT2]

I would call lund. They seem to know these transmissions pretty well, and from what I know work with PBD to figure out more stuff. That's all stuff I've seen online, so I would talk to them directly. I'm sure they know much more than me about all the things they can do via software with the 10r80. As someone else said, lund get the midnight performance car to leave super well. They're hitting 3krpm before actually moving it looks like (). Lund tuned that car, it has a stock trans... I'm sure something could be done for you too. HP Tuners costs like a few hundred or more just to unlock the late model stuff, so I would avoid using it if possible.
And for the converter, I'm sure it's just a matter of time before circle D comes out with one. I've sent them a message to see what they have to say. Most likely they're working on one right now so.

Maybe with a smaller pulley you can get the flash stall up. Throw in some kind of software work up for 10r80 launch and you should get that 60ft down.

the msd works fine, you have to flip the wires on the 3 coil

Thanks .
Do you think the 2 step will help the 60 on a PD blower/stock converter car ?

it's possible with a trans brake for sure

 

[Mustang Mods]

How are you launching? 2 step on a stock converter is not a good fit for a PD blower.

Also I am a PBD dealer when you want to switch. Let me know if I can help.

Thanks man.
I have varied the launch stalling between 1800-2200 and 60 ft is fairly consistent 1.85.
I am trying to see how much I can get out of the stock stage 2 whipple tune and holding out for the possible stage 3 /E85 tune .

I am going to try pulleying down to 3.625 pulley and see how it does .
The 137 trap speed with the 3.75 pulley should have been good for a low 10 second pass but best is 10.70.
With the 3.75 pulley and 98 plus boostane (I think it may be same with 93 and boostane ) I am seeing max timing at 19* and -2 knock (I think that all the tune has )
I will run Ms109 or 98 plus boostane with the 3.625 pulley and considering adding a BAP to be safe but fuel looked real good on the 3.75 .

I will eventually do an after market tune when I ditch the cats but wanting to run it with stock exhaust for as long as I can .

Made 698rwhp today on 93 octane with 100+* heat index on the 3.8 pulley with SW catless longtubes through stock exhaust.

Nice numbers . Stage 1 or 2 ?
How much torque ?
If stage 2 , I am sure you are going to want a smaller pulley to get over the 700 hump but I don’t think numbers are your thing .
When are you doing your next 1/2 mile event ?

I just dropped down to 3.625 and still seeing -4 to - 2 KR with a can of boostane added to a full tank of 93 .
I am hoping to improve my ET this weekend but will run 98 plus boostane or MS109.
