The Death Trap - Street Build TRD Supercharged 2011 SR5

Yeah duder. Cold is amazing! Do you have a boost gauge?

 

Yessir! Hitting peak of 6lbs right now, but i only have a 2.8 pulley..

 

Right. Well that's exactly where I was too with the 2.8. Maybe a bit less a WOT, not sure why, supercharger getting to the point of needs to be rebuilt, maybe....

Also, can you believe I'm actually looking into getting a larger crank pulley made?... some guy who just started at my workplace has a side company that makes custom parts. Theoretically I could get 2-3psi more. Would be similar to the NST pulley that went OOP a couple of years ago.

 

Yeah i was at the same amount of boost on the stage 1 tune when i had all my cats and stock ypipe. Now with the stage 2 tune and no cats, its making the same amount of boost, but less restriction, so its making alot more power.

Lol hell yeah i can believe it! Youre already running a 2.0 pulley and thats obsurd

So bigger crank pulley means more s/c pulley rotations right?

 

Right. Spin the blower faster by either shrinking the blower pulley, or enlarging the crank pulley. NST's pulley was about 7" in diameter.

 

Also... stage 1 tune being OV tune?

 

Whats your plans if you end up blowing the motor? Do you have the ability to rebuild everything? Id be scared shitless running as much boost as you do..

 

No sir, stage 1 Ucon tune.. stage 1 is for stock exhaust with cats. Stage 2 is for no cats on the headers so it increases cam timing and ignition timing and more fuel from what i understand..

 

I should probably be more scared than I am, to be honest. But I think being wise about fuel, having a safe engine computer, and having water-meth injection makes it work. But yeah, I've thought about the possibility of catastrophic engine failure. I would probably remove the engine myself and take the block to get rebuilt with a lower compression ratio. Still we'd probably be talking a $2-$3k hit. I'd buy a $500 beater truck to drive around while the work gets done. I dunno. I like to think, if it hasn't blown up yet, after 4000 miles of having that pulley, it probably won't. And believe me, I'm not going super easy on it.

 

Oh I see. Good to know. I think it's high time I called URD and got them to tell my what duty my injectors are doing.

 

Sounds like a good backup plan. I think youre right about having fuel, a good tune/computer, and meth injection to keep things running cool. Those three go a long way to keep everything running well.

Definitetly do that! There is a section in Utune that shows the IDC and that it your duty cycle.. i dont know enough about it all to find it though. My truck is still running like shit, its starting to look like i may have to pull everything apart and go back through the install to make sure everything is right.

 

Oh... I didn't know you were having issues. What's been happening?

 

Truck was stuttering and running lean at wot in 3rd and 4th gears at 3k rpms (during WOT) before i put my headers and ypipe on. Now its just falling flat on its face at WOT at different rpms. Idk wtf is going on.. ive gone through just about everything, still no dice. Been having problems since the end of june

 

Oh man. That's outstandingly disappointing. Not sure what to say, could be a whole host of things. Did URD say anything about it?

 

Yeah man its been a pain in the ass since day one. Starting to get frustrated with it.. URD has been trying to help me, i even sent my ucon back to them to test it and it never acted up in their test vehicle. Something is definitely wrong mechanically with my truck

 

Man. So what happens? You floor it and it randomly cuts out? No codes?

 

@rjbiii

Sorry, didn't mean to imply you haven't looked at your codes, lol. I believe you when you said you went through everything, was just curious.

 

Pretty much, randomly cuts out at wot, no codes whenever this happens. I have had a P0353 a couple of times, and a P0111 once, but those are very intermittent and never occur when i am having any issues. The truck has got me stumped. Im starting to wonder if the cam gears are lined up properly. I remember having all the timing marks lined up 100% though during install. I feel like if they werent, something catastrophic wouldve happened to the motor by now since ive put about 5k on the blower and ucon since install.

No worries at all buddy, definitely didnt take it that way, i keep an ultragauge plugged in at all times to monitor engine coolant temp, intake temp, and to read any trouble codes it throws. So far it hasnt thrown many, relative to all the problems ive had. Although a few weeks ago it did start misfiring on all cylinders for no reason.. started out as a P0304 and then moved to all cylinders.. not sure what happened then, but sent my ucon to gadget for testing and he said it was good and that he couldnt replicate the problems. After putting the ucon back in my truck, it hasnt misfired since then.. just the stuttering continued until equal length ypipe and headers went on a week ago. Now it just falls flat on its face at wot. Im convinced theres something stupid and simple thats causing all these issues, its just a matter of time until i get it figured out. Hopefully i dont blow the motor in the meantime

 

@rjbiii wow. My mind is literally blown. That is such a nightmare. I don't think that it's the cam gears, I read a forum post a while ago where a guy installed his wrong, and it ran shitmazingly pretty much all the time. I think he'd bent some valves too. It doesn't make sense to me that it would only happen some of the time. But I can't completely rule that out either.

 

Yeah dude its a fucking mess. Im almost to the point to where i wish i wouldve left it stock.. if i can actually get it figured out though, the truck could be a monster..
