737rwhp uncorrected for those that think chargers aren't affected by altitude.

Only made 52PSI on the dyno, and at the track it makes 59PSI peak. Lights in the building actually dimmed when Casper climbed up on the charger.

Certainly could use more fuel, and perhaps tuning. How much power does it really make? Not sure. A bunch though. The guys in the shop took cover.

Stock injectors, stock engine, PPE Dual Fueler, McRat EFILive Tuning, PPE GT42R, 4" exhaust, Edelbrock 1792, Mike L. Fuel Cooler, shimmed PRV, electric fan, Mike L. Frankie2/Suncoast trans.

This combo will certainly go over 750hp, but I just wanted to verify that the GT42R is 750+ hp capable, and still streetable.

Congratulations. That's simply amazing! I just wish we could reliably hold that kind of HP on stock internals. I would go that route in a heartbeat.

That sure says a lot about Mike L, trannies!

WOW!How long do you think it'll live?Awesome #'s.

 

[SmokeShow]

Frickin A man!!!!

What are the ultimate goals at hand here? Stock internals are likely on borrowed time so thats expected to be improved next. You have also pretty much maxed out the injectors (haven't you?) so they will likely be next to be tested, no? Then what? Heads??? Cams??? XXXX????

Just amazing all the testing you all do. Wondering why though? Is it just because? I'm not questioning why you do it, just wondering whats the driving force behind you all (McRat crew) doing this for no other apparent reason other than "just because" and to show the public what different setups are capable of.

Either way, its remarkable and certainly much appreciated on my behalf anyways. Keep it up. Its amazing just to track your threads.

Not sure. Far less HP has grenaded the drug trucks, and even Cummins have problems at that level with stock head studs.

I can certainly turn it up higher, but not sure what the point would be if we can't get it to hook up on the dragstrip already. More HP would just hurt our ET's even further.

No, it doesn't make alot of sense.

It's our family hobby, and the McRat Racing sales just allow us to test more stuff than we could normally afford. This is certainly not a "for profit" enterprise!

I predict 800rwhp will be the limits of the stock injectors based on our data, but I hate to even say that when some folk thought the limit of LiLLY injectors was 400rwhp.

HOLY **** PAT. Did the earth stop or start turning backwards? I must have been asleep. :grd:

 

[tarmacblack]

AWESOME!!! Very nice numbers!!!

Any chance we'll see a kit with the new Garrett 4094 in the future?

PS. I couldn't agree more with SmokeShow, it's awesome that you guys are doing this and sharing what you find!!

Someday the LiLLY's will be equal to the LB7's.

Awesome #'s..... !!! Congrads on the HP. Is it still a 6.6L or is it now a 6.2 liter or less???LOL

 

[Kat]

Is it still a 6.6L or is it now a 6.2 liter or less???LOL

:lol:

 

[Wooter]

now all we need is some magazine articles about you or some other high HP Duramax all i hear from my dodge friends is that i will never make high HP.

Hopefully find out later when I get my work done.

 

[Nasty Girl]

That is friggin INSANE Pat!!! Congrats to you and Kat!
Just another statement of potential for the Dmax.

 

[JOHNBOY]

Awesome Job guys!:ro)


For some reason my Wallet is getting sore!

It's going to be an interesting year, that's for sure.

I'll never be the fastest, or the most HP, so I'll just settle for moving the bar now and then.

 

[Lennart]

Way to go! Congrats...

 

[carcrafter22]

Damn you for making my mouth water!! I guess the kids dont really need a college fund.

Congrats McRat team!
