im completely fucken lost.

 

Putting a restrictor AKA welding tip provides a restriction and delays the onset of the wastegate actuating. This allows for more boost as less exhaust gases are bypassed around the turbine wheel. That is the "pill mod"
The vacuum tank delete is that on our cars, not the solstice or the sky, that we have this little expansion tank on the front of the engine. Theres a solenoid on the front of the block to which a vacuum line goes to our bypass (BOV) valves. Removal of this tank reduces lag as the total volume to which must be pressurized is drastically decreased so this is seen as an anti-lag mod.

 

Oh god... this is the last forum this should be posted on, lol.

Ok, I am glad its posted here, but there are gonna be some mad booooooost nooooobs coming in here blowin there cars cuz of this. I think you should just make a statement that if they don't understand, and they don't have HPT, then they should GTFO.

 

no custom tune=no pill mod

 

Yeah, you're right. I took down the pix, I left them on HPT for those that need them though.

 

Strange I have logs that show it pegged at 255 kPa until 6500 with my car and the MBC. I see 242 kpa at 7400 if I rev that high.

 

guys stop redneck modding ur new car and get a boost controler and do it right.

 

blowing up turbo ftw. lol because that means you have to get a new one and that means gt30 yay

 

And who says this isn't the right way to do it? Its the same damn thing as a boost controller, just operates a bit differently. You need to brush up on your knowledge of boost controllers.

 

lol i agree that it essentially is the same thing but still not something im going to push. Makes more sense just to get a gt30 and throw this k04 in the trash

 

I wouldn't be so quick to dispose of the K04. It really depends what you want to do with the car. Myself, I want to circuit race it, and need the low end grunt which the K04 has plenty of. If I were drag racing, then I would be looking other directions. I will be doing a K04+ build this winter that will put some of these GT30 cars to shame.

 

Enjoy your max of 22psi with HPT then.

And I agree Mkriebs with your post saying this shouldnt have been posted here, which is why I left it out of the guide. People will be trying to pill mod their stock cars...

And I agree, I hold ~22 to 6800 RPM no problem

 

I have a MBC but I took it off now because I actually like the ECM controlled wastegate better. It comes on smoother and harder in the lower gears. It made a little difference in acceleration in third gear but I hardly ever need to do a full third gear pull on the street. I might try the restrictor mod on mine with a valve that I can open and close.

 

^A .045 pill should net 25ish spike and stop the 30+ ones! Something to try out

 

i thought the stock turbo was small and didnt have any lag...or am i wrong?

this sounds like a fast way to blow up actually.

 

Funny, I have almost 10K miles on my pill mod. Put down 322/391 and trapped over 114 this past weekend. 0 KR

Edit: And what is the difference if you raise boost via a Table in HPT, a MBC or a restriction in the line?

 

I can get around the 22 psi from HPT. That won't be a problem. Logging it will be the problem. For now...

I will be running an AEM tru-boost controller in place of the stock solenoid, and installing a GMPP stage 1 for logging purposes (unless HPT comes out with OS tweaks which is not likely).

 

I have a E-01 in my attic that I thought about using, I just dont want the giant screen in the car LOL. Which led me to the pill mod.

 

You have a PM.

 

I might try it but I already have clutch slip issues at 22 psi.

 

Yea, I def hear you on that one! I reworked the timing tables for the MUCH higher load then the 200 in HPT and I feel like the car makes more power. Im certainly trapping higher then I used to!! Im afraid to goto the dyno again and hear my clutch crying tho lol.

What are you going to go with for a clutch if you dont mind me asking?

 

Pill mod with stock tune or any MBC with the stock tune is certain early engine death if you ask me. Even at ~15 psi the car knocks 3-4* in the midrange on the stock tune. The knock has a lot to do with the factory tune having the A/F commanded at 0.95 lambda (14.0 A/F for those who do not speak lambda) all the way to 4500 rpms. Running 20 psi or more at 14.0 A/F without using extremely high octane fuel ( C-16 or at the vary least a 50/50 mix of 93 and 110 fuel) is going to cause tremendous amounts of KR.

 

Well put! I still wouldn't try it without a tune, even if i DID want to destroy my engine.

 

And I def agree!!

 

i just find that unpredictable. at least with a boost controller u wont worry about suddenly overboosting.

U could make one for probably as cheap as ur welding tip.
