All you LML guys, check this out!! Simply amazing!!

Fleece performance and PPEI performance dyno'd 720hp and 1300ft/lbs of torque with stock injectors and cp3 conversion!! S468 turbo and built tranny.

Then fleece dyno'd his LML it made 740 with 100 over injectors only running stock pulse width LOL could double the injector duration wonder what his numbers would be!!! Can't wait to get an LML one day

So no lift pump on either one? If you go to the trouble of switching to CP3, why not lift pump too? I'm also curious as to whether this is with or without emissions in place.

Prokopchuk_9 · March 15, 2014

Fleece is just gearing that second truck up now, they'll hold rail pressure for a dyno pull. I'm sure once he's got it pulling or on the street hell have a lift pump. You would have too. I would say the first one he's talkin about has one, they usually don't mention that stuff because it's a supporting mod...something you just buy without question..

I doubt any emissions stuff is on there lol...highly doubtful. That cp3 concersion kit is pretty straight forward I've checked it out. Plus it supplies an extra 5k psi rail pressure than a cp4...

The first one, probly under$10,000 total in mods for 1300ft-lbs...pretty awesome

Yeah that's a lot of bang for your buck. The first thing anyone does around here is lift pump. Then get an Edge and think they're badass, followed by ruining their injectors lol.

I guarantee you if I had an LBZ it would have Maggy or MBRP system from the down pipe. They sound so much happier when they can flow.

Prokopchuk_9 · March 15, 2014

When mine was a single I ran a 3" diamond eye down pipe and 5" straight pipe, custom expander off the down pipe.

Prokopchuk_9 · March 15, 2014

Now I have 4" directly off the turbo and turns to 5" after a couple feet

Woah, they're supplying 34-35k rail pressure with a cp3?

It's a stroker pump, pretty sure they get an extra few k out of it...not entirely sure tho. The main reason for the swap is because the cp4's are prone to failure when running bigger tunes...

chrisuns · March 16, 2014

Just impressive is all. Cp3 is only rated for 26k, which by experience I know they can be pushed to 29-30ish (limited by rail pressure sensor and injectors). I just didn't know 35k was for sure doable. Granted, it doesn't really surprise me too much considering the cp3 is solid steel. From my understand, injectors have always been the main hold-back from high pressures like that.

Yeah, the cp4 is a worthless piece of crap IMO. - Prone to failure is speaking highly of it. They go out on stock jetta's and Powerstrokes like flies too.

I am surprised he put a stroker in it though, the big advantage is LML injectors return MUCH less fuel than previous systems. I would imagined 800-850 would be completely in the realm of possible with a stock cp3.

Ya those piezo injectors are pretty awesome...just the cp4 sucks. Somebody is selling a "fix" kit for them can't remember who...maybe fleece or alligator.

I'm not sure on rail pressure, i did the fuel rail shim kit. It will hold 26k-27k rail pressure even on the hot tune...I'm sure I've read a thread on DF were guys were getting over 30 with some stroker pump or something. I dunno...

Prokopchuk_9 · March 16, 2014

Was thinking about doing this with mine, I know a guy that did it. Turned out awesome!!

Those number are insane for the stock injectors.... So tempting, but I don't have any extra money right now!

Screw it Max out the visa hahah

chrisuns · March 17, 2014

Short of a complete redesign, I don't think the cp4 is "fixable". In hindsight, you probably could max out the r.p. to over 35-40k. - If you just "dead-hung" the pump, as it doesn't have any relief. The FPRV would pop open around 28k on LBZ-LMM though.- Not to mention limited by the dangers of building pressure passed the FRP sensor since it only reads 29k bar iirc. The lml fprv is controlled electronically and the rail pressure sensor will read to 31.9k. So it would be safe to run rail up to that.
