I thought Lenny's = DDP

am I mistaken?

wouldn't be the first time!

 

maybe..... i dont know. FYI at the time when they were new they were 900 but worth everypenny when compared to the old 370's in terms of cleanliness. wish i could have got don m to kick out some a buddy of mine had some don ms and they were cleaner than those stage 4s youve got but still those stage4s were really clean

 

So does anyone know how Don's Hot Rod 370's compare to DDP4's? Been thinking about going bigger but still undecided. Price is about the same...

 

I'm pretty sure Lenny's 4's = DDP4's

I realize washer thickness makes a considerable difference, but MAN these things are WAY cleaner than the 215's I pulled! my idle haze would put tears in your eyes and getting up to speed was a smoky affair.

I'm surprised the 62 cleans them up, but I guess 55psi w/ a ported head IS a decent amount of air

 

WOW! Well the HTB2 62 didnt even start clearing up the 435's
the 64 does a better job though.

The 435's are around 55 HP over 370's.
BTW i'd gladly lend my 435's to one who dynoed DDP's 4's to see dyno differences. as to burn clean i believe the DPPs are better!

 

well, I haven't really gotten a chance to hammer on it during the light of day without the streets being wet, but it seems to be cleaning up pretty good

 

Your good C.A.T. = Crazy A.. Texan
DDP = Dynomite Diesel Performance which = Lenny

 

I'm almost totally clean out the tailpipe at WOT

 

Does anybody know who has the cheapest prices on Dynomite Diesel DDP4's for a 12 valve?

I have put 2 hours in and can find nothing.

Seems like nobody discounts them from DDP's MSRP?

 

I might have mine for sale soon, I'm kinda wanting to go bigger

 

Bigger mine worked to over 600 on #2 only and mine are the old 4's you have more then enough injector

 

you've got twins though

I figure if I'm only making 1400*, I can use a little more fuel

maybe I'll just hit it w/ some water/meth

 

Here's what I don't understand about that....
You egt's are manageable right now... sure water/meth will help lower them but why make them unmanagable?

 

Any small injector with loads of rack travel will smoke like a coal train.

Adding the larger injector allows the fuel load to be injected faster, reducing smoke. Generally speaking, of course.

Much like increasing timing advance does with smoke control. Advancing injects the shot earlier in the cycle, so the tailing end of the shot is later.

As rack increases, pressure decreases per unit quickly after about 14mm's on the 215 P7100. Not only is the fuel injected later it is also injected with lower pressure. Things only get worse as you try to inject fuel into an already high pressure cylinder. Underpenetration and poor air utilization are the number 1 cause.

 

my last truck would bury the 1600* pyro quickly, but it seemed plenty managable to me

Don, what do you think a set of 191's would do for me? any actual gains at WOT? man, those 215's smoked at any throttle, not just WOT, so glad they're gone
